Design of Automatic Building Temperature Measure and Control System Based on CAN Bus |

| Abstract: | An automatic building temperature measure and control system based on CAN bus was designed. Taking single chip AT89S52 as its core, the intelligent node and network configuration of the system were set up by CAN bus technology and digital temperature sensor DS18B20. The total frame and key software flow of the system were given, and the test was done. The result shows that room temperature control can meet the design demand, with merit of simple frame, energy saving, good real time and high reliability. |
