This design uses the MCU to complete the automatic control of heat supply system with remote control, while saving energy. The design can be divided into the main pipeline installation in the main pipeline control system and installed in buildings room control system two parts. Two control system basically consists of the CPU motherboard, other peripheral circuit and electric valve. CPU motherboard main temperature acquisition, processing, pressure, flow measurement, storage, control, alarm, and other functions. The article uses the 77E58 single chip microcomputer as the core control device, realize the whole automation control. A hardware design discusses the controller basic module for example temperature detection circuit for DS18B20, I/O expansion port with 8255and converter using the AD694 chip type and function. Expounds the principle, and various functions of the interface between, extension, data transmission, communication protocol and drive. On the other ha
