Abstract: In this paper the design and development of intelligent motor monitoring system. The host computer using the "configuration" software to monitorthe lower machine using the electrical machinery intelligence protection device, between the two RS485 to RS232 communication method, RTU message transmit format of communicate with in order to Modbus communication protocol. Microcontroller integrated treatment for three-phase asynchronous motor overload, phase failure, over voltage, under voltage and other fault characteristics, protection, real-time monitoring and effective protection of the motor. Can not only improve the management level of factory automation, and mechanical and electrical equipment, at the same time-line monitoring of the conditions of the electrical and mechanical equipment in a timely manner to prompt the equipment failure and specific information, statistics, equipment run time and power consumption, suggesting that the management personnel of the equipment maintenance, management, access to equipment can consumption conditions, thereby reducing equipment accident rate, extend the life of the electrical equipment to protect the normal production of the factory.
Key words: Intelligent motor protective device; on-line monitoring; King view; Modbus RTU; RS485
