Design and implementation of wireless monitoring and control system for protected environment

As the information monitoring and equipment control points for facility agriculture production environmental monitoring were scattered, a universal wireless monitoring system was designed with functions of self-organization jump and data transmission. With JN5121 module that has ZigBee wireless data transmission function as the core, sensor input and equipment control output interfaces were designed and front-end wireless nodes for local information acquisition and equipment control were developed. Host hardware with multi-resource interfaces based on ARM9 core was designed and monitoring function and man-machine interface were implemented using MiniGUI on Linux platform. Environmental information collection and analysis and integrated control of the equipment were accomplished through the unified coordination and command to the front-end wireless nodes. Results show that the system has characteristics of low cost, high universality, good expansibility and high reliability; and can be easily applied to environmental monitoring and control under different conditions such as greenhouse, field and animal house, to meet different needs of users.
