Abstract: This paper designs and realizes group control system for greenhouse based on CAN-bus and introduces the communication structure of group control which uses CAN-bus. It analyzes the hardware and software design of greenhouse environment control system. Results show that the monitor of the I/O equipment and the stable running of greenhouse control system can be realized by the application of multiple hosts working mechanism of CAN. It runs the system in a greenhouse is presented and obtains good effect.

Key words: group control system, CAN-bus, communication structure
