Abstract:

High power consumption of large-scale public buildings has become the bottleneck in the development of China's building energy efficiency.A method based on 89C51 microcontroller and can-bus is adopted to achieve energy-saving temperature controller.The paper gives the general design and pins connect of the major circuit diagrams,and designs the system software in accordance with the functional requirements and the actual circuit with the detailed flow chart given.The software and hardware of the chip microprocessors are debugged to achieve corresponding functions.

Key words: temperature controller;89C51 microcontroller;can-bus;circuit principle diagram;system s software
