Greenhouse Data Acquisition System Based On Embedded Technology And Wireless Sensor Technology

As traditional sensor communication with cable, a large number of wiring would be very difficult in the green house and not conducive for farming. Wireless transmission technology could deal the problem. On one hand, many agricultural monitoring system use computer as controller.Computer need high level environment. On other hand there is also single-chip computer system as the central controller detects. Microcontroller's performance is limited, can not meet complex control strategies and video processing and conducive to the application of new technologies. In recent years, some system use wireless sensor to measure agricultural greenhouse, but the system only used in laboratory. For the above, a system for capturing greenhouse factors is designed and analyzed in this paper. The system performs the following functions:(1)Measuring Greenhouse crop growth environment temperature, relative humidity, CO2 concentration and light intensity and other environmental factors in real-time.(2)Storage, display, analysis and processing of real time data. This function is core of the wireless monitoring system, the main task is to store sensor data, for users to view historical data in future. Then fit the data, give a valid value, and display the data to the user in intuitive graphical.(3)Video monitoring plants in the greenhouse .User just stay at home can monitor plants in greenhouse with this function can find pests and diseases in first time.The functions of system meet the design requirements in practice. System to achieve the acquisition and data display and processing functions. The system use Linux as embedded systems, system is scalability.In the end, summarized the results, future research directions are discussed.
