Abstract:
Measurement and control system performance is key to greenhouse crop high quality， high yield and efficient cultivation. In view of the current greenhouse measurement and control system needs to solve the problems， reducing cost， reducing power consumption， improving anti-jamming capability， improving real-time and communication. The paper proposed application of CAN bus based on microcontroller MC68S08QG8 measurement as communication profile， and introduced a single intelligent node of the hardware design and software realization in detail. A simple CAN application layer protocol was designed. The running result shows that the system has performances of simple structure， high reliability and strong real-time.
