Key Technology And Application Of Public Transportation Information Service System

With the country’s economic development and people’s living standards improve, travel requirements are also increasing, the service requirements of urban public transportation system along with improved.Traditional public transport system infrastructure can not meet the needs of people travel.Application of information technology to provide public transport information service is an important means to enhance the level of service the public transport system, but also the development trend.Transit information services provide the means to have a variety of ways, one of the most important and most common means is the electronic stop sign,While many cities use electronic stop sign, but mostly rolling broadcast information to provide information services, passengers can only passively receive information, a general lack of ability to interact with the stop sign.If widely adopted outdoor touch screen mode, the construction costs, maintenance costs and equipment costs are unbearable loss.With NFC technology matures, smart phones generally support NFC technology features Ihat passengers interact with electronic stop sign provides an effective means of.Therefore, this paper focuses on the study of the application NFC (Near Field Communication) technology in public transport information service.Through this technology will enhance the ability to interact with electronic stop sign and passengers and reduce the construction cost electronic stop sign, for promoting public transportation information services to enhance the quality of great significance.This paper proposes the use of NFC technology with electronic stop sign NFC phones and application service framework for information exchange methods of public information services to achieve the application,Were investigated NFC service lifecycle management module, NFC service incubator module, making NFC services framework has the ability to change and upgrade.Through the development of data exchange standards and combine Java reflection, so NFC tag data is automatically converted into Java strongly typed data, the user can directly access to data of public transportation information via NFC tags Java objects.In the data access layer for NFC tag data link capabilities by introducing Activity reception and data access layers.On this basis, the overall architecture proposed NFC services framework, and the relationship between the thread resources occupied NFC services framework and the various threads were studied.Finally, under the Android development environment to build method demonstrates NFC Services Framework environment, describes how NFC services framework for efficient application development, and through the application of project-related functions and features to show the NFC services framework.This study on the improvement of public transport interactive information services and reduce the cost of public transportation information service building has a very important significance.
