Design Of Control System In Fungi Greenhouse Based On Cortex A8Platform

China is one of the largest producer of edible fungi in the world, Thecurrent greenhouse extended and applied continuously, it makes the greenhousecrop growth of fungi has been an important means to enhance the developmentof edible mushroom in china. But at present our country is a large part of theproduction of edible fungi are still in the traditional manual mode of low yield,small size. Vigorous development of the Internet of things technology makes theembedded system technology and wireless network technology to monitor cropsgrown in a greenhouse become inevitable means to modernize agriculture.Different fungi demand growth environment is not the same, the same typeof fungus growth in demand for different periods of the environment are not thesame. With respect to the fungi short growth cycle, growth phase and morefeatures, we need according to the law of the growth of fungus itself, takecorresponding control in intelligent environment, provide the most beneficial tothe growth of fungi in the external environment to achieve the purpose of funguswith high yield and good quality in greenhouse.Paper constructs embedded systems based on the ARMv7architecture,proposed a control system based on the fungus greenhouse cortexA8platform design. The perception layer collecting temperature and humidity, theconcentration of CO2, the environment of the scene data through ZigBeewireless network transmission and communication, the final realization of datadisplay and summary in the PC and embedded system development board,through the man-machine interface control device, so that the relevantenvironmental parameters are adjusted, to control greenhouse to fungi.Compared to traditional microcontroller based embedded control systemscortexA8fungus greenhouse platform with low power consumption, stronganalog video output, strong anti-interference and rich human-machine interfaceprocessing systems and so on. On the transmission side, compared with thetraditional greenhouse monitoring system of cable connection wiring difficultiesand disadvantages of agricultural operation, the ZigBee wireless transmissionmodule to help solve the problem of limitation of the cable system, and throughthe establishment of network nodes, to facilitate the overall display andintegrated management on a host or gateway. Through the above, we can realizethe intelligent control of greenhouse.The main work of this paper:Firstly, a stable and reliable embedded hardware and software platform wasselected as research, through the fungus greenhouse structures in the laboratorysimulation environment, measuring and debugging environment on the spot.Secondly, based on the Fungi m greenhouse system for inspection andanalysis, select the appropriate fungus plant as the research object, and complete the design and construction of the sensor module, data acquisition module,signal module and human-computer interaction module.Finally, through the study and development of the embedded developmentboard, completed the procedure of the software part, including the customizationand transplantation of the WinCE system, greenhouse control system softwareinterface design.
