摘要: 针对现有刮板输送机圆环链张力检测方法采用有线方式无法实时检测圆环链张力的问题，设计了一种基于RFID的刮板输送机圆环链无线张力传感器。该传感器选用电阻应变片作为敏感元件，通过电桥式应变测量电路将应变片检测到的应变信号转换为与圆环链张力相关的电压信号，电压信号经放大、滤波等调理后送入无线射频芯片nRF24LE1，通过nRF24LE1的无线发射模块发送到无线采集分站，实现对圆环链张力的实时检测与数据无线传输；根据实时检测到的圆环链张力及张力变化情况，可以判断圆环链的松紧程度，有效预测与准确判定圆环链的断链故障。实验结果验证了该传感器的可靠性。Abstract: In view of problem that existing tension measuring methods of round link chain of scraper conveyor could not detect tension of round link chain in real time by using wired method, a wireless tension sensor of round link chain of scraper conveyor based on RFID was designed. The sensor uses resistance strain gauge as sensitive element, strain signal detected by resistance strain gauge is converted to voltage signal relating to tension signal through bridge strain measurement circuit. The voltage signal is sent to nRF24LE1 after being magnified and filtered, and then it is sent to wireless collection substation by wireless transmission module of nRF24LE1, so as to realize real time wireless measurement of tension of the round link chain and the data wireless transmission. According to the real time tension and tension changes situation of round link chain, the sensor can judge the degree of tightness of round link chain, and can effectively forecast and truly determine broken chain fault. The experimental results verify the reliability of the sensor.
