电动机故障录波监测装置通讯及通道校正方案的研究与开发

THE STUDY OF COMMUNICATION AND CHANNEL CALIBRATION SCHEME OF ELECTRIC MOTOR FAULT EQUIPMENT

电动机故障录波监测装置分析软件是运行人员分析处理故障的有力工具。为保证信息的可靠、快速的传递 ,采用基于 CAN总线的通讯网络。使故障录波监测装置的故障信息及时上报到后台 PC网络节点上。同时为提高装置的测量精度 ,提出了一种基于线性最小二乘原理的录波器通道校正方法 ,该算法具有简单、实用。

The analysis software of electric motor fault recorder equipment is useful tool for maintenance man to analyze and handle fault.The system use communication net based on the CAN bus to ensure that the fault message of recorder equipment can be transferred to PC net node fastly.On the other hand,to improve the measurement precision of motor fault recorder equipment, the paper proposes a channel calibration approach based on the linear least square method.The proposed approach is simple and practical and has high precision.
