Design of Integrated Experiment System for Frequency Control Based on Industrial Network

Taking three-phase induction motor as the object of control,both design and realization of the network system which composed of different communication protocols were introduced,including the measurement procedure for motor speed,the communication program of industrial Ethernet and the read-write program of DP communication inverter;the speed control interface of host computer and touch screen were given to have smooth speed regulating of asynchronous motor realized.The system employs network technology for data transmission so as to benefit remote monitoring of enterprises and to improve the operation reliability of motors,as well as to promote the automation level of enterprises.
