Application of wireless communication technology in the measuring and controlling system for greenhouses

The structural characteristics of control system and design method for the greenhouse group based on the wireless communication technology were introduced. The control system is characterized by the hierarchical divergence and chain structure, as well as master-slave mode. The wireless communication technology, which does not require communication circuit, can shorten the initial building period and reduce the investment of the measuring and controlling system, and the system is constructed flexibly and upgraded easily. The hierarchical divergence and chain structure can make the system be able to be large or small and be transformed conveniently. The structure and design method of the measuring and controlling meter, whose key part is C8151F005, and the design method of interface circuit and controlling software of the industrial personal computer(IPC), which is the host computer, were described respectively. The methods make system simple, reliable and easy to control.
