Design and implementation of taxi meter based on JAVA (attachment: source code paper sql file)

Summary

In our country, the taxi industry is a new industry that emerged in the early 1980s. With the emergence of taxis, taximeters also came into being. But at that time, there was no enterprise in the country that could produce it, so the meter at that time was imported from Taiwan. Taiwan is the main production site of fares, currently 90% of the world's fares are produced in Taiwan. Today, there are hundreds of companies producing taximeters in my country, mainly concentrated in Beijing, Shanghai, Shenyang and Guangzhou. In our country, the economy is still in the stage of development. Due to the limitation of people's living standards and road traffic, the ownership rate of private cars will not increase greatly in the short term, so taxis play an important role. The taxi meter is an indispensable and important instrument on the car. It is a special intelligent instrument responsible for the taxi's charge. The first enterprise in my country to produce taximeters was Chongqing Crane Factory. The earliest taximeters all used mechanical gear structures, which could only perform simple metering functions. It can be said that the early taximeters were just odometers. With the development of science and technology, the second generation of meter has been produced. It adopts the combination of hand-operated computer and mechanical structure, and realizes half-mechanical and half-electronic. At this time, it can also complete the work of pricing while metering. The development of large-scale integrated circuits has produced the third generation of fares, that is, fully electronic fares. Its functions are also constantly improving. When the single-chip microcomputer appears and is applied to the taximeter, the model of the modern taximeter is basically available. It can complete the basic tasks such as metering, pricing, and display.

As taxis are an important part of urban transportation, the health and development of the industry has also received more and more attention. The car meter is the transaction criterion between the passenger and the driver. It is an important symbol of the development of the taxi industry and the most important tool in the taxi. It is related to the interests of both parties to the transaction. A meter with good performance is necessary for both taxi drivers and passengers. Therefore, the research on the car meter is also very valuable. Taximeters can not only solve the problems of electronic system miniaturization, low power consumption, and high reliability, but also have a short development cycle and low investment in software development, especially for small batches and multiple varieties of products. Through the design of this topic, you can comprehensively use the knowledge you have learned about digital systems, C# language, etc., and learn how to use MyEclipse software editor and jdk software editor. Research content: The billing function can be realized according to the billing standard. The meter is a tool used for fair trade settlement between the operator of the taxi and the consumers who take the taxi. Therefore, whether the meter is accurate or not is directly related to the economic interests of the operator and the consumer. According to the relevant laws and regulations of the country, the taxi meter is one of the first batch of working measuring instruments included in the national mandatory inspection, and it is also one of the six key measuring instruments that the national quality and technical supervision department has strengthened management in recent years. As taxis are an important part of urban transportation, the health and development of the industry has also received more and more attention. The car meter is the transaction criterion between the passenger and the driver. It is an important symbol of the development of the taxi industry and the most important tool in the taxi. It is related to the interests of both parties to the transaction. A meter with good performance is necessary for both taxi drivers and passengers.

System development background

With the increasingly fierce competition in the taxi market, the taxi pricing business is facing an unprecedented development opportunity. Seizing the opportunity and responding to the market quickly is an urgent task for taxi companies to gain a competitive advantage. The rapid development of the information industry and the improvement of the technical level enable us to keep up with the development of the times, establish an advanced information processing platform, combine science and technology with the excellent management experience of the enterprise, and promote the progress and development of the enterprise.

Based on a deep understanding of the complexity and importance of taxi pricing business data management, we have launched a taxi meter system, which realizes the rational planning of taxi pricing business processes and the integration of basic data, providing comprehensive and efficient services for taxi companies. Timely and accurate business processing provides a basic guarantee, and at the same time provides a solid data foundation and analysis means for the company's internal management and decision support.

System flow chart

A system flow diagram is a graphical representation of the flow of information through a system, the flow of parts through a system, and the flow of ideas through a system. Flowcharts are mainly used to illustrate the flow of a process. This process is the management process necessary to complete a task.

The system flow chart of the taxi pricing system is shown in the figure


data flow diagram

Database flow diagram: From the perspective of data transmission and processing, it expresses the logic of the software development in a graphical way. For example: What is the thinking logic of the car rental pricing system? The main expression tool of the structured system analysis method is the data flow diagram, and the data flow diagram is a graphical method to represent the software model.

The system data flow diagram is shown in the figure


Hierarchical block diagram of system function modules

The structure of software sometimes becomes the architecture of software, which is the most essential thing in a software system. Good architecture means practical, efficient and stable. Hierarchy diagram is the most ubiquitous software architecture used in SD method.

Hierarchy diagrams are used to describe the hierarchical structure of software. A rectangular box in the hierarchical diagram represents a module, and the lines between the rectangular boxes represent the calling relationship between modules. The system hierarchy is shown in the figure

thank you

      Thank you for seeing this. I believe that the pretty boys and girls who see this have only one idea in their hearts: they want source code, papers, and database files. All the information can be received by "  private message " and I will give you a friendly reminder. After finishing the project, we must pay attention to one point, that is, the weight and format of the paper! Of course, if you have a cute little guy who just started programming and wants to practice, you can also " private message " me, the video course materials of Java and Python, as well as the learning roadmap and employment prospect analysis video can be used as a reference for you, everyone pay attention and Like! ! !
