(1) Source of subject
In recent years, with the progress of the times and the rapid development of the economy, people's living standards have also been greatly improved. Therefore, the demand for materials and the quality of life have also undergone rapid changes. In terms of travel, China's car ownership continues to increase. For example, the current share of automobiles in our country has greatly increased compared to before. At present, China has become a major automobile consumption and automobile production country in the world. Relevant data show that during the period from 2002 to 2006 in China, the proportion of new cars accounted for 60%, and the number of private car ownership reached nearly 30 million, and the annual growth rate of cars exceeded 50%. The number of cars will reach about 60 million, and it is estimated that the number of cars owned will exceed 200 million by the end of 2017. So, that leads to half the cars being parked in disorder. While promoting urban development, parking lots have become an indispensable part, but problems such as too many cars and few spaces, and parking difficulties have also followed, which are particularly prominent. With the rapid development of science and technology, the rapid popularization of the automobile industry and the popularization and rapid development of various motor vehicles, people have put forward higher requirements for the supporting facilities of the vehicles, especially the parking lot. The parking lot management system came into being under such circumstances of. Public toll parking lot is an important component of static traffic. It provides a traffic place with zero speed for parking. The birth of the parking lot management system can not only effectively manage vehicles and solve traffic congestion. It also promotes the construction of regular transportation facilities, while also reducing the probability of vehicle theft. In terms of technology, it is combined with other information systems and matched with existing intelligent systems. It has good openness and scalability, and is easy to manage. Through the market research and analysis some time ago, I have a preliminary understanding of the advantages and disadvantages of various parking software. For example, some traditional parking lot software is generated from traditional data records to replace manual entry. These software can only be sighed in the face of intelligent parking lot management software. The disadvantages are as follows: ①The system is closed, unable to realize network management, let alone support e-commerce. Due to the backward technical background, traditional software cannot realize network management or only support partial network applications, let alone support e-commerce, and cannot adapt to the requirements of enterprises in the Internet age; , Traditional software cannot achieve real-time dynamic processing of inventory information, pre-forecast and forward-looking information; ③ little consideration is given to management. Software is still not free from the shackles of tradition, and external reporting is the purpose of its existence.
In recent years, the management of parking lots in our country has gradually matured. Applying the above technologies to the management of parking lots, combined with the management requirements of users, the parking lot management system has become an important part of traffic settings, providing users with a An efficient management method, convenient and effective service and a safe, comfortable and intelligent living space promote the development of the environment. In order to meet the customer's requirements, an easy-to-operate parking lot management system is designed. The system consists of the following major modules: system information management module, parking space information management module, IC card information management module, toll management module, ticket reading information management module, etc. Among them, the parking space information management module and the reading ticket information fully solve the problem of single information, and can dynamically process the information in the parking lot, and park and pick up the car efficiently. In response to the issue of little management consideration, the administrator sets permissions to prevent some people from abusing their power and making profits. In view of the closed system, network management cannot be realized, and e-commerce cannot be supported. When logging in to the system, you can choose whether to log in as a user or an administrator. The process is all network management.
(2) Research Status
Parking lot management is actually information management. In the informatization of the parking lot, it involves the informatization of parking space management, the informatization of car owner management, and the informatization of parking information management. Doing a good job in informatization will help improve the management efficiency of the parking lot and enhance the competition of the parking lot. force.
To improve competitiveness, we need not only a good hardware environment, but also good customer service, and the way to achieve these goals is informatization. This topic, aiming at some information in the parking lot process, carries out informatization processing on it. In the parking lot process, it mainly involves fixed parking space information, free parking space information, car owner information, parking information, etc. Through the informatization of the above links, the standardized management of files is improved, which lays the foundation for future inquiries and statistics.
The intelligent management of the parking lot is the collective name for the vehicle charging and automatic equipment replacement management of the modern parking lot. It is a high-tech electromechanical integration product that completely bases the parking lot on computer management. According to Luo Haijiang, the product manager of Hengye International Holdings Group Co., Ltd., it started in 2001, and now it is becoming more and more perfect. The functions are more and more oriented to the actual needs at home and abroad, and the system operation is more humanized. Nowadays, the intelligent management of parking lots has passed the stage of following and imitating foreign products in the early stage, and has entered a stage of product innovation, keeping up with market demand and growing continuously. At present, there are more than 400 domestic companies that generate listening and planning systems, among which domestic parking lot system products account for about 80% of the market share, and foreign parking lot system market accounts for 20%. In Europe and the United States, it is understood that the parking industry in some European countries has a history of 50 years, and has reached a virtuous circle and orderly development. The parking industry has also become a large industry with an annual output value of one billion dollars. The annual revenue of the parking industry in the United States has reached 26 billion US dollars, accounting for 3.25% of the national GDP. And our country's parking gear license plate recognition firmly occupies the position of the lead singer. The card reader plays an important role in the parking lot management system, and now it has developed from the early simple contact card (magnetic card/ID card, etc.), to the inductive IC card, and then to the RFID card. The RFID card has the most right to speak.
The entrance part of the traditional parking lot management system is mainly composed of card readers , vehicle detectors , parking lot controllers, automatic barriers , and vehicle detection coils. The card readers use inductive IC cards. Most traditional parking lots use short-distance For the card reading method, you must stop and swipe the card to pass, which is very inconvenient to use. You need to roll down the window and reach out to swipe the card, and some need to get out of the car to swipe the card. It is easy to get wet in rainy days , and swiping the card to park up and down the ramp is likely to cause accidents such as car slipping and collisions. Slopes are also very scary for new drivers. Swiping the parking card has the disadvantage of slow traffic speed, especially during the peak time of entry and exit, it is easy to cause congestion. The parking lot adopts the whole process of video surveillance and dynamic feedback information, and there is still a certain guarantee in terms of safety. Therefore, in terms of optimization, this system adopts the combination of cards and tickets. In terms of card readers, RFID cards are used to solve the problem of inductive short-distance IC cards and greatly improve efficiency. For vehicle entry, the license plate recognition function is added to recognize the license plate, enter and exit the parking lot, and is aimed at users who have members in the parking lot. For temporary users, there is a ticket reading function, which can dynamically reflect the current parking space situation. The whole process adopts video monitoring, which is omni-directional and has no dead ends as much as possible.
The traditional parking lot management system cannot handle real-time dynamic processing, cannot protect the owner's information well, and improperly handles the authority of the manager, etc. This system can handle these problems well. Among them, the functions of system information management, parking space information management, IC card information management and other functions have solved this problem well. System information management functions include adding role information, managing role information, adding user information, managing user information, managing role information and managing user information. The module can query, edit and delete roles and users. Parking space information management includes adding parking space information and managing parking space information. The management parking space information module can query, edit and delete the owner's parking space information. IC card information management includes adding IC card types and managing IC card types. IC card information management can query, edit and delete the owner's IC card information. Charges can be divided into cash charges and card charges. Generally, VIP users charge by card, temporary users charge by cash, and software management implements hierarchical authority restrictions. For the person on duty at the exit, he can enter the charge management after logging in, during which all charges for the exit will be automatically recorded in the name of the person on duty and stored in the computer database. Since the duty officer is limited by authority and cannot enter higher software menu items in the system, he cannot interfere with the data recorded by the computer; the superior manager can query, check or print a duty section or any period of time or even the entire parking lot at any time. work record. In this way, the loss of parking fees and errors in financial statistics are fundamentally eliminated. At the same time, the automatic operation of the system eliminates the economic losses caused by favored cars and Bawang cars. Design a series of simple but not simple pages, as opposed to functions, improve the speed and accuracy of information processing, and be able to query and modify the situation of the parking lot in a timely, accurate and effective manner, thereby improving efficiency.
Research objectives, content and means of the subject:
The research goal of the project is to realize a parking lot management system that integrates a series of functions such as querying parking space status, car owner information management, parking space information management, IC card information management, and charging management. The new parking lot management system perfectly combines electronic technology and life concept, and provides an intelligent, simple and practical humanized parking lot management system. Efficiently handle the entry and exit of the car, and the entry, storage, and deletion of various information, effectively solving the problems of parking difficulties, traffic jams, etc., the owner can clearly see the status of the parking space, save the owner's time, and avoid some unnecessary things occur, greatly increasing safety and solving traffic problems. Car owners can enter or leave the parking lot in a short time and enjoy a comfortable and fast life.
The research content is: a parking lot management system that realizes car owners entering and exiting the parking lot and related information processing. During the system implementation process, the data table will be designed around these core functions, and then the corresponding outline design and detailed design will be carried out, and finally the system will be tested. Then it will analyze the development background of this system, the current status of the parking lot and the advantages of this system; then conduct demand analysis and its corresponding data flow chart; system analysis and its functional structure, etc., including system information management, parking spaces Information management, IC card information management, fixed owner parking management, temporary vehicle information management, toll management, printing management, system function operation, etc. In system information management, including adding role information, managing role information, adding user information, managing user information, managing role information and managing user information modules can query, edit and delete roles and users; employee information will be set in it and permissions, etc.; in the management of parking space information, including adding parking space information and managing parking space information, the management parking space information module can query, edit and delete the owner’s parking space information; in IC card information management, including adding IC card types, managing IC card type. Management of IC card information can query, edit and delete the owner's IC card information, and process the smart swiping card to make it more convenient for users to enter and exit; in the parking management of fixed car owners, the parking information of car owners can be queried and deleted ; In temporary vehicle information management, the parking information of temporary vehicle owners can be queried and deleted; in charge management, including adding charge information and managing charge information. You can choose to be a monthly user or an annual user. Correspondingly, the management charging information can charge the car owner's fee, and can query and delete the car owner's charging information; in the printing management, print the information that needs to be printed, including the information about the fixed car owner and the temporary car owner Printing and printing of the ticket machine; in the system function operation, you can operate the main system, log out or log in. Then it will carry out overall design and system architecture design; database design and detailed design; system testing and its corresponding functions; system analysis; system maintenance; system evaluation and finally a summary of the paper.
When testing the system, it is necessary to test several situations and make corresponding records. The post-maintenance is also the top priority. A good software lies in whether the post-maintenance is perfect. Bugs are repaired in time, so that car owners can enjoy a high-quality life. Do not delay its time, and be efficient in the true sense. Summarize a lot and improve the deficiencies. Finally, the problem of difficult parking and traffic jam can be solved. In terms of database, it must be handled well to ensure the safety of car owners' information, double safety, car safety and information safety.
The methods and means used in the study: the topic is the design and implementation of a web-based parking lot management system, which is realized by combining the front end and the back end. The front end uses jsp. A cross-platform dynamic web page standard, using java as the scripting language, embeds java code into html code, separates web page code and web page logic, and realizes the functions required by dynamic web pages. The user submits the data through the form, the JSP obtains it dynamically, and accesses the database to dynamically create this web page [3]. In today's society, JSP is adopted by many large and medium-sized enterprises. JSP plays a vital role in Java and is an indispensable part of J2EE. JSP is the first choice for developing web applications, it simplifies the development of web applications and maximizes the benefits. The background is implemented with the programming language J2EE. As an enterprise-level application specification J2EE, it is an open platform for the public. It provides a multi-level distributed application model and a series of technical specifications and components designed and developed for enterprises to develop software, with good compatibility, portability and security. Different developers follow the basic specifications, and J2EE suppliers support different J2EE standards drawn up internally, which solves the compatibility of information products used by enterprises at the back end. Nowadays, this specification has been affirmed by everyone, and is used by most enterprises for practical operation to improve development efficiency.
The system adopts the MVC design pattern. The characteristic of this method is that its logic layer and presentation layer are separated, and the function module and the display module are separated. At the same time, it also enhances the scalability, portability, maintainability and reusability of components of the application.
The B/S structure adopted by the system is browser and server structure. Under this structure, the user interface is all implemented through browse, that is, the front-end implements part of the transaction logic, and the server-side mainly implements the transaction logic. The powerful functions are realized through the browser and the development cost is saved. For enterprises, the B/S structure is a better choice than the C/S structure.
Functional realization: When the car is not in the parking space, the related technology detects it and sends the information to the system. The system processes the information and gets the result. The parking space is free, and a reduced full page of the parking lot shows that the parking space is free on the page. On the contrary, when an empty parking space enters the vehicle, a car information can be entered into the system, and the system will process it and display on the page that it has been parked.

System Research Background and Significance
In recent years, with the rapid development of my country's economy and the continuous improvement of people's living standards, profound changes have taken place in material needs and lifestyles. Cars, which used to be luxury goods, have gradually entered the daily life of citizens. With the popularization of automobile consumption and the rapid popularization of various motor vehicles in a wide range, vehicles have put forward higher requirements for their supporting facilities, especially parking lots. Parking is "traffic with zero speed", and parking lots and ancillary related facilities are an important part of static traffic. The parking lot fee management system was born along with the new thing of the public toll parking lot.
Most of the current parking lots have the following problems, such as management loopholes, system reliability, strong independence, cumbersome charging process, high labor intensity, low parking lot utilization rate, and easy loss of fares. Aiming at these problems, the parking lot system is designed from the following aspects. It is optimized for management, using a combination of credit card consumption and cash payment, and the system is billed by time. Adopt Java high-level programming language and WEB related technologies to develop and design management system software to realize network management operations. The optimized system is easy to use, efficient in service, transparent in charges, prevents the loss of fares, improves reliability and improves the work efficiency of operators.
Research status
Parking lot management is actually information management. In the informatization of the parking lot, it includes the informatization of parking space management, parking information management, and car owner management. The development of informatization work is conducive to improving the management efficiency of the parking lot and enhancing the competitiveness of the parking lot.
To improve competitiveness, we must first have a good hardware environment and good customer service at the same time, and the way to achieve these is informatization. This topic, aiming at some information in the parking lot management process, carries out informatization processing on it. In the parking lot management process, it mainly involves fixed parking space information, temporary parking space information, parking information, car owner information, etc. Through the informatization of the above links, the standardized management of files is improved, and the foundation for future inquiries and statistics is laid.
Parking lot intelligent management is a general term for modern parking lot vehicle charging and equipment automatic management. It is a high-tech mechatronic automation product based on computer processing in the parking lot. According to Luo Haijiang, product manager of Hengye International Holdings Group Co., Ltd., it originated in 2001, and its development is becoming more and more perfect. The functions are more and more oriented to domestic and foreign needs, and the system operation is more humanized. Today's intelligent management of parking lots has gone through the early stage of imitation and learning of foreign products, and now it has entered a stage of product innovation, keeping pace with market demand. At present, there are more than 400 enterprises that produce listening and planning systems in China, among which domestic parking lot system products account for about 80% of the market, and foreign parking lot systems account for 20%. , It is understood that in Europe and the United States, the development of the parking industry in some European countries has a history of 50 years, and has reached a virtuous circle and orderly development. The parking industry has also become a large industry with an annual output value of one billion dollars. The annual revenue of the parking industry in the United States has reached 26 billion US dollars, accounting for 3.25% of the national GDP. And our country's parking lot license plate recognition firmly occupies the position of the lead singer. The card reader plays an important role in the parking lot management system, and now it has developed from the early simple contact card (magnetic card/ID card, etc.), to the inductive IC card, and then to the RFID card. The RFID card has the most right to speak.
The entrance part of the traditional parking lot management system is mainly composed of vehicle detectors , card readers , parking lot controllers, automatic barriers , and vehicle detection coils. The card readers use inductive IC cards, and most traditional parking lots use In the short-distance card reading method, you must stop and swipe the card to pass, which is inconvenient to use. You need to roll down the window and reach out to swipe the card, and sometimes you need to get out of the car to swipe the card. It is easy to get wet in rainy days , and swiping the card to park up and down the slope is likely to cause accidents such as collisions and car slipping. Slopes are also very scary for new drivers. Swiping the parking card has the disadvantage of slow traffic speed, especially during the peak time of entry and exit, it is easy to cause congestion. The parking lot adopts the whole process of video surveillance and dynamic feedback information, and there is still a certain guarantee in terms of safety. Therefore, in terms of optimization, this system adopts the combination of cards and tickets. In terms of card readers, RFID cards are used to solve the problem of inductive short-distance IC cards and greatly improve efficiency. For vehicle entry, the license plate recognition function is added to recognize the license plate, enter and exit the parking lot, and is aimed at users who have members in the parking lot. For temporary users, there is a ticket reading function, which can dynamically reflect the current parking space situation. The whole process adopts video monitoring, which is omni-directional and has no dead ends as much as possible.
The traditional parking lot management system cannot handle real-time dynamic processing, cannot protect the owner's information well, and does not properly handle the administrator's authority, etc. This system can handle these problems well. Among them, the functions of system information management, parking space information management, IC card information management and other functions have solved this problem well. System information management functions include adding role information, managing role information, adding user information, managing user information, managing role information and managing user information. The module can add, delete, and modify roles and users. Parking space information management includes adding parking space information and managing parking space information. The management parking space information module can add, delete, and modify the owner's parking space information. IC card information management includes adding IC card types and managing IC card types. IC card information management can add, delete and modify the owner's IC card information. Charges can be divided into cash charges and card charges. Usually VIP users charge by card, temporary users charge by cash, and software management implements hierarchical authority restrictions. For the person on duty at the exit, he can enter the charge management after logging in, during which all charges for the exit will be automatically recorded in the name of the person on duty and stored in the computer database. Since the duty officer is limited by authority and cannot enter higher software menu items in the system, he cannot interfere with the data recorded by the computer; the superior manager can query, check or print a duty section or any period of time or even the entire parking lot at any time. work record. In this way, the loss of parking fees and errors in financial statistics are fundamentally eliminated. At the same time, the automatic operation of the system eliminates the economic losses caused by favored cars and Bawang cars. Design a series of simple but not simple pages, as opposed to functions, improve the speed and accuracy of information processing, and be able to accurately and efficiently query and modify the situation of the parking lot, thereby improving efficiency.

MVC design pattern
MVC is the abbreviation of Model View Controller Model-View-Controller. It is a pattern for designing web programs. Model (model) is the part of the program that handles the logic of the code. View (model) is the part of the program that processes data. Controller (controller) is the part that handles data transmission and interacts with business logic. The parking lot management system adopts the MVC design pattern, which is convenient for developers to modify or debug code, and avoid code mixing together. Unable to locate quickly when encountering a problem. And MVC layering also simplifies development. Different developers can develop these three logics at the same time, which improves development efficiency and saves time for developers.
Introduction to JSP
JSP is actually a simplified Servlet design, an object-oriented dynamic web technology standard. It uses Java as the scripting language, and can embed java code into jsp pages to separate code from business logic and realize dynamic interaction. Users submit data through forms or hyperlinks, and the data is transmitted to the corresponding Servlet, which is processed by Java code to form dynamic interaction. JSP is used by most enterprises today and is indispensable for J2EE. It simplifies web development, increases efficiency, and reduces business expenses.
jQuery
Query means query, more convenient and quick query page control, simple syntax. jQuery is an excellent JavaScript framework following the prototype, compatible with a variety of browse (IE6.0+), not only can easily operate documents and DOM, handle events, realize animation effects, but also easily realize AJAX interaction, compatible with CSS3 [4]. jQuery also provides developers with the ability to create plug-ins on it, which encapsulates JavaScript functions, write less ..do more ... is the purpose of jQuery.
Intelligent function introduction
RFID card technology
RFID is radio frequency identification, which is a wireless communication technology. It converts radio electrical signals into radio frequency electromagnetic fields, and transmits the data attached to the tags on the items to achieve automatic identification and tracking. Unlike barcodes, it does not need to be within the range of the reader, and can also be added to the tracker.
Today, RFID technology is widely used in most industries. Attach the data label to a set of machines in production, so that the manufacturer can track the production progress online. At present, it can also be applied in the library, which is convenient for management and readers to find books and so on. It can also be used in the parking lot. The radio frequency transponder on the car can facilitate the charge management of entering and leaving the parking lot and avoid unpredictable problems. Improve the efficiency of parking lots.
License plate recognition function introduction
License plate recognition technology is a technology that monitors vehicles and automatically extracts license plate information for processing. License plate recognition plays an important role in the current traffic system. Based on graphic processing, pattern recognition and other technologies, it analyzes the image of the positioned vehicle to obtain the license plate number of each vehicle and complete the recognition process. Through some means of processing, the management of parking lot charges can be realized. The parking lot management system adopts this technology to manage the vehicles entering and leaving the parking lot more conveniently and quickly.
system analysis
Feasibility Analysis
technical feasibility
In the design of the parking lot management system, the MVC (Model-View-Control) design pattern runs through the entire system, and the framework adopts the combined structure of SpringMVC+JDBC.
- Model layer
The model layer is mainly logic processing. In this system, data persistence is provided, and JavaBean encapsulates business logic Service. - View layer
The parking lot management system uses JSP to realize the view layer. - control layer
SpringMVC technology is used to handle the interaction between the foreground request and the business logic layer.
The MVC design pattern is applied in the design of the parking lot management system, which is convenient for developers to design codes. Since these three logics can be carried out simultaneously, the efficiency is improved and time is saved, and because of the layering, the code is isolated, which is convenient for developers to operate. . And the parking lot management system adopts RFID card and other technologies to facilitate vehicle access, increase intelligence, and facilitate management. It can be concluded from this perspective that it is feasible to develop smart parking lots.
economic feasibility
It is mainly to evaluate the economic benefits of developing the system. According to the survey, most public places have problems such as parking difficulties and few parking spaces. The efficiency of the parking lot is very low, which leads to a decrease in the income of the parking lot and is not safe. In response to this situation, it is necessary to analyze the cause and process of the low efficiency of the parking lot, and propose improved countermeasures to improve the efficiency of the parking lot. After analysis and investigation, we found that the parking lot management system is quite useful. From this point of view, it is feasible to develop an intelligent parking lot management system. According to the time spent on consulting information and framework design time, it takes about 3 months to realize the basic functions. From January to April 2017, it takes about two weeks to realize the test of related functions and code implementation. For The interfaces written by the intelligent functions will wait for the technology to be introduced and then run in later, and the implementation needs to be determined. In general, the design can be completed in April. According to the system requirements, the system needs to cooperate with the camera, introduce RFID card technology, etc., and it will cost a certain amount of money, which is within the estimated range. From this point of view, it is feasible to develop a smart parking lot.
operational feasibility
The development tool used in the development is eclipse, which can support running on various computers, and is easy to operate and easy for users to use. Operators can use this system after a simple explanation. From this aspect, it is feasible to develop an intelligent parking lot management system.

system design
This chapter includes three parts: system class analysis, core business design, and database design. Among them, system class analysis needs to give system class diagrams and class descriptions. It should be noted that only core business classes need to be given when class diagrams are given. Auxiliary classes such as interface classes and database connection classes do not need to be given. If there are many classes involved (including the contents of the classes), the inter-class relationship diagram should be given first (the classes in the diagram have only names and no attributes and methods), and then give the class diagram of the specific class in the single class description, and the class diagram also needs to be drawn with WORD.
The core business design mainly describes the message coordination between classes when a specific business is completed, and is expressed in a sequence diagram. The sequence diagram can be drawn with other tools, but it cannot appear in other colors.
The database design mainly describes the objects that need to be persisted in the system, and an ER diagram needs to be given. If there are many entities (or entity attributes) involved in the system, the method of layered drawing is also used. The top-level diagram shows the relationship between entities, and the lower-level The graph is drawn specifically for each entity.

系统测试
停车场管理系统设计完之后需要进行一系列的测试，调试过程中内部环境和外界因素的变化，会影响系统的运行和操作，当系统适应这些变化后，慢慢趋于完善，达到预期想要的结果，这就是系统测试从头到尾一直要做的工作。
根据本系统的功能情况，以黑盒测试为主，白盒测试为辅。黑盒测试：将项目看成一个黑盒子，在不去考虑项目其他情况、只知道系统功能进行的测试。它的任务就是检测系统的每个功能是否可以正常运行以及操作结果是否正确。白盒测试：与黑盒测试相反，是将项目看成一个透明的白盒子，要求操作员必须知道项目流程、项目代码，按照规格说明书的规定检测功能是否符合要求，对操作员要求较高。

0 前言
停车场智能管理是现代化停车场车辆收费及设备自动换管理的统称，是将车场完全基于计算机管理下的高科技机电一体化产品。据恒业国际控股集团有限产品经理罗海江介绍，其兴起于2001年，发展的到现在日渐趋于完善，功能越来越面向国内外的实际需求，系统操作也更加人性化。如今停车场智能管理已经经过了从早期对国外产品的跟随和模仿阶段，进入到了一个产品创新，紧跟市场需求并不断壮大的阶段。目前国内听策划出系统生成企业有400多家，其中国产停车场停车场系统产品约占市场份额的80%左右，国外停车场系统市场占20%。而在欧美地区，据了解，欧洲一些国家的停车产业发展已有50年的历史，并且已经达到了一种良性循环和有序发展。停车产业也已经成为年产值十亿美元的大产业。美国的停车产业每年收入越达到260亿美元，占全美GDP的3.25%。而我国的停车挡车牌识别，牢牢占据主唱的位置。读卡器在停车场管理系统中扮演着重要的角色，如今它已由早期简单的接触式卡（磁卡/ID卡等），发展到感应式IC卡，再到RFID卡。而RFID卡是最具有话语权。
传统的停车场管理系统入口部分主要由读卡器、车辆检测器、车场控制器、自动道闸、车辆检测线圈组成，读卡器采用的是感应式IC卡，传统的停车场大多采用近距离读卡方式，必须停车刷卡通行，使用非常不方便，需要摇下车窗伸出手刷卡，有的还需要下车刷卡。下雨天容易被淋湿，上下坡道停车刷卡容易造成溜车、碰撞等事故，坡起对于新司机也是非常恐惧的。停车刷卡更有通行速度慢的缺点，尤其是在进出高峰容易造成拥堵。停车场采用的是全过程视频监控，动态的反馈信息，在安全方面还是有一定的保障。 因此，在优化上，本系统采用卡票结合的方式，在读卡器方面，采用RFID卡，解决了感应式近距离IC卡的问题，极大程度地提高了效率。对于车辆进入加入了车牌识别功能，识别车牌，进出停车场，针对于在停车场有会员的用户使用。对于临时用户来说，有读取票功能，动态的反应当前的车位情况，全过程采用视频监控，全方位，尽量做到无死角。
传统的停车场管理系统无法实时的动态处理、对于车主的信息也无法进行很好地保护、对于管理者的权限处理不当等问题，本系统都有很好地处理这些问题。其中的系统信息管理功能、车位信息管理功能、IC卡信息管理等功能良好的解决了这个问题。系统信息管理功能包括添加角色信息、管理角色信息、添加用户信息、管理用户信息、管理角色信息和管理用户信息模块可以对角色和用户进行查询、编辑和删除。车位信息管理包括添加车位信息、管理车位信息，管理车位信息模块可以对车主车位信息进行查询、编辑和删除。IC卡信息管理包括添加IC卡类型，管理IC卡类型。管理IC卡信息可以对车主的IC卡信息进行查询、编辑和删除。收费可以分为现金收费和卡收费，一般是VIP用户进行卡收费，临时用户进行现金收费，软件管理实行分级权限制。对出口值班员来讲，其登录后可进入收费管理，期间该出口所有收费均自动记入该值班员名下并存入电脑数据库。由于值班员受权限限制，不能进入系统中更高的软件菜单项，所以对电脑所记录的数据无法干涉;上级管理者可以随时查询，核对或打印一个值班段或任何一段时间乃至整个停车场的工作记录。这样就从根本上杜绝了停车费用流失和财务统计的失误，同时系统自动运行，杜绝了人情车、霸王车造成的经济损失。设计一系列简约不简单的页面，与功能相对，提高信息处理的速度和准确性，能够及时、准确、有效的查询和修改停车场的情况，从而提高效率。
