Application of CAN2.0 Protocol in the Heating Energy Saving System

Heating saving energy is important in the study of saving energy. CAN is a high-performance and high-reliability build bus, transmission distance is very long, it can hang node on optional position in availability distance, the nodes are connected in parallel, and do not interfere with each other. By using the CAN bus technology, the control center connects CAN module, and the CAN module connects temperature sensor and valve controller. The temperature sensor gleans information that the control center controls heating valve according to the temperature information, and make room automatic control. The experimental results show that the system can stable operation. The system has been installed in our university.
