The Greenhouse Supervisory Control Systerm Based On Wireless Sensor Network

abstract:In this paper, the routing protocol and control protocol is built on the basis of ZigBee. It designed based on the wireless Sensor nodes deployment characteristics in the greenhouse. This system improves the environmental parameters of greenhouse more real-time monitoring capability, and greatly reduces the indoor wiring, make the whole monitoring system more flexible and effective installed in every corner of the greenhouse.In this paper, greenhouse wireless sensor network monitor system is based on the network layout characteristics of greenhouse, take into account of practicability, low cost, higher robustness.We adapt the idea of modular design, and mainly do the following jobs.Completed the digital circuit design of sensor data acquisition and processing module, wireless data transmission module, output control module, power management module, serial communication module.In order to meet the needs of a variety of sensors, obligate out a variety of hardware interface. The software of the system can realize5function module of wireless sensor network, node sensor data acquisition and processing, node output control, data wireless communication and control center software system. Focus on the terminal node, routing node and network coordinator of the network communication algorithm and routing protocols, put forward improved routing algorithm design and control algorithm design based on the the APTEEN agreement. Solve the network data transmission problem between the end nodes and network coordination. According to the system design node module, establish a control system, and experiments show that using ZigBee wireless sensor network to establish monitoring system for greenhouse breeding is feasible to monitor, it satisfies the needs of wireless monitoring, at the same time, provides a new solution for the realization of the greenhouse breeding intelligent control.
