| With the development of economy and technology,the owership of electric bicycles will continue to grow rapidly,and how to effectively solve its growing prominence of theft and traffic safety issues will increasingly become the users focus of attention.Compared with the traditional anti-theft method, the electric bicycle remote information sensing and monitoring system based on networking technology has the characteristics of safe, reliable, easy to use, low cost, etc, will become the mainstream of electric bicycle anti-theft.This paper presents an electric bicycle remote sensing information and monitoring system based on C/S and B/S mixed mode architecture,which integrates sensor technology, GPS positioning technology, wireless communication network, information transmission technology and dynamic web database technology, has the function of anti theft monitoring, displacement alarm, real-time positioning, status detection, safety warning and so on.In this paper, the overall framework of the. system are analyzed based on the research background, status, significance and key technologies of the system. The system is divided into three parts:the vehicle terminal, data transmission center and remote monitoring platform. The design and implementation of data transmission center and remote monitoring platform are studied in this paper. The test results are given from two aspects:function and performance. The data transmission center was developed based on Apache Mina network application framework, realizes the information exchange between the vehicle terminal and remote monitoring platform,and the system has a high TCP long connection number(31500),a shorter transaction response time(<0.29s), and more gentle system resource consumption curve (CPU usage, the available physical memory and the number of threads), namely:data transmission center is more stable and can basically meet the electric bicycle industry which demand of high concurrency high-intensive I/O operations and shorter transaction response time of applications. The remote monitoring platform hierarchical structure is designed by the Spring and Hibernate framework. The data storage layer, data access layer, business logic layer, control layer and view layer are built. The functions of user registration and login, status information display, terminal parameter configuration and vehicle remote monitoring are realized,and in the number of 300 concurrent users, the success rate of all types of transactions is more than 98%, the average transaction response time is less than 5 seconds, CPU occupancy rate curve and the overall number of available physical memory is relatively flat, its performance is relatively stable. |
