基于WSN的小区自行车防盗系统的设计

Design of bicycle anti-theft system for community based on WSN

针对小区管理的需求,将无线传感器网络引入到小区自行车防盗系统中。以ATmega128L单片机为核心扩展了断线检测模块和以CC1000芯片为基础的无线通信模块,设计了无线传感器网络的电子锁节点和Sink节点。规划了无线传感器网络拓扑,设计了具有较高稳定性的简单无线通信协议,基于监控主机以多线程的方式实现了防盗监控软件。实验验证了方案的可行性,仿真验证了多节点情况下,通信协议的稳定性。

In order to meet the needs of community management,this paper applies the technology of wireless sensor networks to bicycle anti-theft system for community. We use ATmega128L chip as microcontroller of WSN＇s node,and extend the break detection module and the wireless communication module with CC1000. On the other hand,we propose a simple self-organized protocol for wireless sensor networks,and then design anti-theft software on monitoring host using multi-thread technology. The feasibility of bicycle anti-theft system is verified by experimental conclusions,and the stability of the communication protocol under multi-node circumstance is proved by simulation results. The bicycle anti-theft system will be useful for community management.
