【Abstract】 This paper introduces the working principle of electric geothermal control system in intelligent building. Through the research of the electric geothermal system and the characteristics of the intelligent building,the industrial PLC controller is adopted to design the electric geothermal control system of the intelligent building.The lower computer of the system adopts the PLC control module and combines the sensor network to collect the controlled parameters,and the network communication adopts the Modbus bus communication.The upper computer of the system is developed by configuration software,and a visual monitoring subsystem is designed. The communication of the host computer adopts TCP/IP network communication. The system is debugged by programming software and configuration interface, and the debugging result proves that the system design is reasonable and feasible.更多还原
