An Anti-theft Electric Bicycle Tracking System Supporting Large-Scale Users

Electric bicycle is one of the most common transportation means in China. To improve the safety of the bicycles, an anti-theft electric bicycle tracking system (ATEBTS) for large-scale users was designed to track electric bicycles by obtaining various information of bicycles' states and analyzing running conditions. In this system, a microprocessor with Global Positioning System (GPS) modules embedded in bicycles sends data in real-time through General Packet Radio Service (GPRS) and Global System for Mobile Communication (GSM), and an inner G-sensor can fetch real-time state information, such as acceleration and shaking signals. The system designed a message protocol to encapsulate and send these data to servers and also adopted distributed architecture, including Open Fire server cluster, cache queue cluster, database cluster and web server cluster. This specific architecture provides a better performance when large-scale users visit concurrently. To further improve query efficiency, relevant data are inserted into one single node in database indexed by the terminal serial number. With the increasing number of users, tables can be split into several tables according to different dates. And this system will provide services for more than 200 thousands users in Shandong Province this year.
