The Design Of Greenhouse Environment Information Collection System Based On Wi-Fi Transmission

In order to make the canopy management personnel can more convenient and fast to get inside the greenhouse environmental information, this paper used the embedded a serial port turn WIFI module for secondary development, design the greenhouse environmental information collection system based on wi-fi. Based on the position of the upper and lower body into the system within the greenhouse environmental information collection, under a machine by single-chip computer,sensor, display module, a serial port turn wi-fi transceiver modules data acquisition node; Each sampling node using single-chip microcomputer control temperature and humidity, then the acquisition through WIFI module and wireless router to the node’s environment parameter sent to the PC server.The main work is as follows:1. Analyzing the present pattern of greenhouse environmental information acquisition system, determine the overall design scheme of greenhouse environmental information acquisition system.2. The current commonly used wireless communication technology are introduced and compared, analyzed the WIFI network mode, determines the design of data acquisition based on wi-fi.3. According to the system function demand, lower machine information collection node for the design. Information acquisition nodes with low power consumption MCU STC12C5A60S2 systems and control, using a serial port turn wi-fi transceiver module for data transmission.4, PC monitoring software, and to verify this system. Designed a simple simple PC display interface, and chose two information acquisition node in the network data transmission was tested, the test result data collected information acquisition node can accurately display on the LCD and the upper machine, respectively. Show that the system design scheme is basically feasible, and has certain practical value.
