Abstract本发明涉及一种非侵入式电机效率在线检测装置及其控制方法,包括:传感器单元,将电机线电流、线电压信号转换为弱电压信号;信号采集处理单元,对从传感器单元得到的电压信号进行数字化,再经过运算处理得出监测结果发送给通信单元;通信单元,将接收到信号采集处理单元输出数据通过无线网络发送给监测计算机;方法包括:上电初始化;进行原始数据采集;计算各个电机的监测参数;将监测参数的计算结果发送给通信电路板;修改电机的配置参数;判断是否接收到原始数据帧,如接收到,则采集相应原始数据,并发送;返回进行原始数据采集步骤,循环执行。本发明可以快速建立完善的在线电机状态监测系统、安装简单,减小了安装监测系统所需要的工作量。
Other AbstractThe invention relates to a non-invasive electrical efficiency on-line detection device and a control method thereof, and the non-invasive electrical efficiency on-line detection device comprises a sensor unit, a signal acquiring and processing unit and a communication unit, wherein the sensor unit converts line current and line voltage signals of a motor into weak voltage signals the signal acquiring and processing unit carries out digitization on the voltage signals obtained from the sensor unit and transmits the monitoring result obtained by operation process to the communication unit and the communication unit transmits the received data output by the signal acquiring and processing unit to a monitoring computer by wireless network. The control method comprises the steps of initializing in an electrified manner, collecting original data, calculating the monitoring parameters of each motor, transmitting the calculation result of the monitoring parameters to a communication circuit board, modifying the configuration parameters of motors, judging whether the original data frame is received or not, if so, collecting and transmitting corresponding original data, otherwise, going back to the step of collecting the original data, and performing circularly. The invention can build a perfect on-line motor state monitoring system rapidly, the installation is simple, and the workload required in installing the monitoring system is reduced.
