Communication Protocol Design of Temperature Monitoring System Based on CAN bus

Aiming at the temperature control problems of pressroom, using CAN bus as the core design a temperature monitoring system, and propose a communication protocol to apply this system. According to the system requirements, we can set the message frame format, identifiers assignment, communication mode and realization method, give the protocol of the hardware and software design and adopt multi-frame transmission and dynamic priority allocation mechanism to ensure reliability and real-time of data transmission.
