随着城市中各种功能的不断完善，各种井盖也越来越多，由于缺乏有效的监管手段及实时监测办法，城市中各种井盖的丢失或者损坏的现象时有发生。给人们的生活带来极大的隐患。该方案利用433MHz 无线网络，震动开关及 GPRS 技术实现了一种可大范围监测井盖状态的系统。无线智能井盖监测系统，可以实时监测井盖的状态，当井盖被移动时，发出报警信息到后台服务器的监管平台。系统是由传感器、无线传输模块及后台服务组成的实时监测系统。实际试点应用表明，本系统可以起到很好的监测效果。

The civic manhole cover problems such as being stolen or damaged are common phenomenon for the present, causing great inconvenience and danger to people's life. The system in this thesis applies the 433MHz wireless network, vibration-detecting switch and GPRS technology to monitor a wide range of manhole lids. Wireless smart lids monitoring system can monitor the lidsin real-time: when the lids is moved off their original place, the system will give alerts.The system consists of sensor,wireless transmission unit and real-time background service. The system has seen good monitoring effects in the pilot projects.
