地下综合管廊井盖检测报警系统设计

基于STC89C58RD+单片机,设计了一种地下综合管廊井盖报警系统。该系统采用nRF24L01无线通信和RS-485通信方式,通过主机设定并发送指定从机授权码,工作人员用遥控器向指定从机井盖发送相应授权码,则该从机井盖可以被合法打开；如果从机井盖被非法打开,井盖打开时触发行程开关,产生报警信号并发送到主机,主机显示被非法打开井盖编号,此时工作人员便可采取相应措施。试验测试结果表明：系统响应速度快,传输距离远,传输信号稳定,操作简单,安全性能高。

Detection and alarm system for undergroundcomprehensive gallery cover

A detection and alarm system based on MCU (STC89C58RD+) for underground comprehensive gallery cover. The system adopts nRF24L01 wireless communication and RS-485 communication, use theSmaster set up the authorization code, then send the authorization code to theSappoint slave, use remote controller to send accordingly authorization code to the appoint slave, the slave covers can be legally opened; if the slave cove be illegal opened, it will trigger theStravelSswitch, and produce an alarm signal and send it to the master, the master shows the number of illegal opened the slave cover, Then the staff could take appropriate measures. The test results show that the response speed of the system is fast, transmissionSdistance, transmission signal stabilization, simple operation and high safety performance.
