Chapter 1 Introduction
This chapter first expounds the research background of this paper, deeply investigates the current situation of electronic tour guides at home and abroad, then introduces the purpose and significance of this topic, and finally proposes the main research content of this paper and gives the organizational structure of the paper.
1.1 Introduction to Research Background
According to the data in the 2011 China Tourism Industry Analysis Report, the number of domestic tourists in my country in 2011 was about 2.6 billion, a year-on-year increase of 12%; domestic tourism revenue was about 1.9 trillion yuan, a year-on-year increase of 21%; the number of outbound tourists reached 70 million, a year-on-year increase of 22%; the number of tourists and tourism consumption are rising steadily[1]. In 2012, my country's tourism industry will maintain its growth momentum, and its development is relatively optimistic. The role of my country's tourism industry will also become greater and greater.
my country's tourism industry has developed rapidly in recent years, and the ratio of total tourism revenue to GDP has increased significantly every year. The leaders of the State Council and the China National Tourism Administration are very concerned about and attach great importance to the development of the tourism industry. Shao Qiwei, director of the National Tourism Administration, and relevant leaders of the State Administration of Quality Supervision, Inspection and Quarantine have repeatedly stated in their important speeches that they must increase investment in the tourism industry, promote the diversification of tourism products, actively improve the service quality and level of tourism services, and shorten the gap with the international advanced level as soon as possible. In order to effectively implement the spirit of the State Council's "Opinions on Accelerating the Development of Tourism Industry", the functional departments of local governments actively responded to the call of their superiors, and made every effort to develop tourism resources and drive the development of energy production. It is known that by 2015, the number of tourists (including domestic tourists, inbound tourists and outbound tourists) in my country will reach 3.7 billion, and there will be a new standard for the quantity and quality of tourism, which must be in line with the international advanced level. The development of tourism will also drive the total income of tourism, and at the same time solve the problem of difficult employment. We believe that in the near future, my country's tourism industry will enter a new and unprecedented scale, and the tourism market is relatively mature, and is heading towards a new stage of winning and developing with quality.
With the rapid development of my country's tourism industry, traditional tourism methods can no longer meet the diverse needs of tourists. Some problems that cannot be ignored have emerged. For example, the number of tourists traveling by car is increasing year by year, so there is a problem. Assuming that tourists go to a very remote wilderness, their personal safety is a big problem. If there is a system that can wirelessly track and locate now, then they are in any danger
In case of danger, you can call the police wirelessly, ask for support, and get rescued. In addition, many tourists are willing to design travel routes according to their own preferences. If there is a system, tourists can design their own travel plans according to the number of people and characteristics of scenic spots, then the whole journey will be more humanized and convenient. With the development of technology and the arrival of 3G technology, the wireless bandwidth is getting higher and higher, and more content-rich applications can be run on mobile devices, such as video calls, Internet surfing, online listening to music, etc. Coupled with the development of electronic map technology, it also promotes the modernization of tour guide services at the technical level.
With the widespread popularization of mobile phones and the continuous improvement of hardware levels, the performance of mobile phones has also developed rapidly. Since the launch of the Android system in 2007, people have perfectly combined mobile phones and the Internet because of the openness of Android and the rapid development of wireless Internet technology. The mobile phone is not only an ordinary communication tool, but also has more powerful functions, and even the mobile phone can be used as a mobile computer, so the market share of smart phones is increasing year by year. The Android system has a rich graphics system, powerful multimedia functions and map control functions. According to data in November 2012, Android occupies 76% of the global smartphone operating system market, and China's market share is as high as 90%.
At present, the functions of the tour guide system used in various scenic spots are relatively single, and only some simple introductions of the scenic spots are recorded in a device in advance. Manually played by tourists when visiting, the content is relatively boring and not vivid enough, it is difficult to arouse the interest of tourists, and there is a lack of help for tourists in other aspects. There are great disadvantages in the use of such a tourism system: firstly, it is not universal and cannot realize the sharing of network resources; secondly, it does not have the function of automatic navigation, and the quality of these devices is uneven, the amount of information is not rich enough, and the application value in actual tourism is not high. And this article is to design and implement a tour guide system based on mobile devices, not only to make up for the above shortcomings, but also to further increase various practical tourism functions.
Android is an open-source operating system, which is developed in java language, and you can obtain the source code and develop SDK without paying any authorization fee, which has attracted many programming enthusiasts to have a strong interest in it. This article uses the Android platform to develop a self-guided tour guide system. The developed system mainly has the following functions: automatic navigation, scenic spot introduction, audio commentary, etc.
1.2 Purpose and significance of the subject
With the rapid development of science and technology, one of the important signs reflecting the level of a scenic spot is the degree of service informatization of scenic spots, and the main manifestation of the informatization of scenic spots is the application of various electronic tour guide systems. The use of the self-service electronic tour guide system will greatly enhance the level of informatization of scenic spots, marking that the service level of tourist attractions has reached a world-class level. The development and application of intelligent electronic tour guides are still in their infancy in China. The tour guide systems used in various scenic spots are only specially customized for each scenic spot.
The method is used in other scenic spots, the versatility is not strong, the lack of humanized services, poor interactivity, and relatively narrow service areas cannot meet the needs of various tourists. Most of the tourist attractions now use the old-fashioned, single tour guide system, which is not fully functional and cannot be used in other scenic spots. This kind of non-universal equipment has a high cost and does not have too many functions, so it has no value for further promotion. Designing and implementing a powerful and interoperable tour guide system software, which is now basically a smartphone, can not only reduce tourism and manufacturing costs, but also improve tourism quality and enhance the service level of scenic spot information.
This article is to use the Android system of the smart phone to design a self-service tour guide system that can realize the above functions, which can meet the needs of tourists as much as possible during the travel process, facilitate tourists to travel, and improve the quality of travel.
1.3 Status Quo of Application of Self-service Tour Guides
At present, some developed countries in the West basically do not use artificial tour guides in indoor exhibition halls such as museums, but replace some tweeters with a non-tour guide-style electronic interpreter. When visitors enter the exhibition hall, they can receive an explainer and manual at the entrance, operate the explainer to listen to the content according to the introduction in the manual, and put it back to the original place after the tour, so that the next visitor can continue to use it. Using this kind of equipment in the exhibition hall can create a quiet visiting environment, and there will never be any noise. This is the prototype of the electronic tour guide. Some cities in Canada have used a relatively advanced self-guided tour system in tourist attractions. When tourists pass by certain scenic spots during their play, this self-guided tour guide system will automatically play a voice introduction about the history and culture of the scenic spot, and can point tourists to the route to the destination, as well as which shops and accommodations are nearby [2].
In addition, a portable electronic guide device was invented in Massachusetts, the United States. This electronic guide device stores 35,000 items of data including major highways in the continental United States. People can use it to provide some help when making travel plans. The use of this electronic tour guide is very simple. Just input the state name, highway, direction and other information, and a series of information such as restaurants, gas stations, and tourist attractions around it can be displayed at a glance, so this electronic tour guide can be widely promoted and used by tourists. When visiting a scenic spot, as long as you hold an electronic tour guide, you can get the historical and cultural information of the scenic spot in the beautiful background music, which can meet the personalized travel needs of tourists.
In our country, the tour guide services using information technology are mainly websites that provide tourist information, and electronic tour guides are still a new thing. The use of electronic tour guides in my country first appeared in 2000, at the Lijiang River scenic spot in Guilin, Guangxi, and then some scenic spots in other places also introduced this kind of equipment. But its disadvantage is that its functions are relatively single, mainly digital button players and touch-type video explanation systems, such as the electronic guides used in Tianjin Museum and Shaanxi Yellow Emperor Mausoleum. These electronic guides are just a sound player or an information search station[3]. In 2005, the Temple of Heaven Park in Beijing used an electronic tour guide system for the first time. It has the functions of intelligent guidance and automatic explanation. At present, only a few famous tourist attractions in Beijing can provide this type of intelligent electronic tour guide system, such as Beihai Park and the Summer Palace.
Electronic tour guide is the inevitable product of the rapid development of my country's self-service tour guide industry. The earliest research and development of electronic tour guide system in my country was in 2000. The manufacturers who developed and produced this product include Qidong Yuanzhuo Computer Engineering Co., Ltd., Guangzhou New Fulcrum Electronics Co., Ltd., etc. [4]. In recent years, the development speed of the electronic tour guide system has been accelerating, and the functions of the products have been improved day by day.
1.4 The main work of this paper
This article is to use the current mainstream Android operating system, combined with wireless positioning technology, electronic map and other technologies to design a self-guided tour guide system to make people's travel more convenient and intelligent, and make it easier to play. The main function of the system is to provide services such as real-time positioning, scenic spot explanation, route guidance, itinerary suggestion, map display and other services for tourists, especially self-guided tourists.
The following is the main work of this paper:
1. Conduct in-depth research on domestic and foreign electronic tour guide systems, and further study several related technologies involved in this system.
2. In-depth study of Android technology and development interface, and how to use Android to realize some functions of this system.
3. The system mainly includes three layers, namely client layer, database layer and server layer. The server is mainly responsible for accepting and executing client requests and database access functions, while the mobile client is mainly responsible for making request commands, sending requests to the server, and displaying the data returned by the server to the user interface. It is mainly responsible for connecting to the server and command management. Android provides a wireless networking interface, and the server and the client transmit data through the wireless network.
4. This article also expands another identity management function: users with different identities can be identified on the device, including tourists and administrators. Every user who has registered in the system can use his own
The user name and password log in to the system, and the user enters the function interface after logging in. The tourist interface mainly implements some functions in tourism, and the administrator's function is to perform some related operations on scenic spots and tourists, for example, the administrator can add and modify the content of scenic spots.
This system adopts the C/S mode to design, the user client part is implemented on the Android mobile terminal, the server is implemented on a host, and the two transmit data through the wireless Internet.
