Abstract:In order to achieve the user's intelligent control of electrical equipment and the purpose of saving electricity,an intelligent power terminal system based on family heterogeneous network is designed. Firstly,the function of intelligent power terminal system is described which is compatible with WirelessHART protocol,PLC communication and Ethernet communication. Then,the hardware and software design of the system is described in detail. Finally,the test results fully verify the effectiveness of the proposed design scheme.
