摘要
电力线振动过快或共振会危害输电安全,而振动参数往往不易采集。为此设计了一个基于nRF24L01的无线振动检测系统。提出了从加速度信号间接获得振动频率的方法。解决了嵌入式Linux系统下驱动nRF24L01的问题。系统可准确监测视距100 m以内,提高巡检人员工作效率。
The excessive vibration and resonance of power line endangers power transmission, but the relative data of vibration is difficult to be collected. Therefor a wireless system for vibration monitoring based on transceiver of nRF24L01 is designed. Propose a method of acquiring frequency from acceleration. Resolve the problem of driv- ing nRF24L01 on Linux. vibration signal within 100 meters can be monitored accurately. It helps the inspector to increase work efficiency.
