Design And Implementation Of Greenhouse Remote Monitoring System Based On Embedded

In order to meet the demand of the crops growth and improve the economic benefits of farmers, the application of greenhouses is becoming more and more popular, and greenhouse monitoring system in our country is increasingly mature. The environment of the greenhouse is not suitable to layout wires, then wireless sensor technology is the best choice of information acquisition in greenhouse. Because of the high cost and the simple function,industrial control and micro-controller are not able to meet the demand of modern greenhouse.With the continuous development of network technology, and the expansion of smart phone used, APP remote monitoring is a trend of intelligent products. With the phone App remote control is applied in modern greenhouse control system, farmers can decouple from the scene,receive temperature and humidity parameters anytime and anywhere, and control shutter, fan and other actuators in greenhouse.This thesis designed and implemented a remote monitoring system of greenhouse based on embedded. The system applied wireless sensor network technology, embedded technology,Windows remote desktop platform and mobile phone APP remote monitoring. SHT10 sensors was used to collect temperature and humidity parameters, and a Zigbee wireless sensor network based on CC2430 will be established.The sink node conveys information to the controller through serial port. S3C2440 processor and Linux 2.6.30 operating system are used in the embedded controller, and the controller is also using LCD touch screen. The main program writen in the QT language has a good man-machine interface. Controller with DM9000 card is able to connect to the Internet through RJ45 meshes. Mobile phone APP and embedded controller connect to the PC server through the TCP/IP connection. PC server is responsible for the delivery of temperature and humidity parameters and mobile phone control commands, and the server also have a desktop remote monitoring platform, matching the Oracle database, it can also query the history of temperature and humidity value. The app have many functions such as real-time monitoring, the outside actuator controlling, inquiry of historical data, alarm, and setting the parameters in place of the functions of the LCD touch screen.The developed system has been tested in a simulation greenhouse. The temperature andhumidity parameters the different node collected can be accurately displayed in the LCD touch screen. And the peripheral actuators can be controlled through the touch screen. The server side can transmit information accurately, query history database,send control commands. The app can realize the function of remote monitoring.
