In order to obtain the temperature conditions of switchgears quickly and accurately and to avoid temperature rise faults,the temperature rise conditions were analyzed.According to the Modbus-RTU protocol,a multi-channel temperature monitoring system was designed through connecting multiple measurement points.Serial communication between the microcomputer and many thermometer instruments was implemented.The software interfaces designed by Visual Basic are succinct and clear.And the system has flexible functions of parameter setting,data saving,temperature curve display,etc.The testing results show that the multi-channel online monitoring temperature error is ±0.5 K,the whole system runs well. And it is worthy of extension and application.
