摘要
在此提出基于键盘扫描算法的多路断电预警系统的设计,通过设计相关的接口电路将断电信号接入AT89C51单片机,经过改进型键盘扫描算法检测后送往PC机监控软件,实现对机房电源的无人远程监控。该系统设计简洁,能对多路电源同时检测,并在PC机软件上进行分析得出结论,预警时效性高,准确性高,目前已在民航汕头空管站信标台机房投入使用。
A multi-channel outage warning system was designed based on the keyboard scanning algorithm.The power-off signal is sent to AT89C51 MCU by related interface circuit,and then sent to the monitoring software of PC after detection by the improved keyboard scanning algorithm to perform the remote monitoring of the power supply in the unattended equipment room.The system is concise,can detect multiple power supplies at the same time and generate the results from the analysis of PC software.Due to its high timeliness and accuracy,the system has been put into service in the omnirange radio beacon room of Shantou Air Traffic Management Station of Civil Aviation of China.
