| As long as the deepen application of the Object Network Technology in the facilityconstruction, a hot topics in research was coming out, that was how to achieve mobile operationthrough convenient and high-efficiency multiple resources utilization, in order to increase theproportion of the efficiency and output for the high tech facility in manufacture. The mobilecollection terminals could display, transfer and collect the information from wireless sensornetwork high efficiency. This terminal would play an important role in the Object NetworkTechnology application system, comparing to the others, it had such advantages of the goodman-machine interaction (MMI) and reliable communication technology. Regarding to theagricultural facility applications, we state our design theory. A mobile information collectionterminal basic on the wireless sensor network was developed, the information collectiontechnology adopts the APC240module of APPCON technology Co., Ltd. to realized the wirelesssensor data collection by the MODBUS Agreement; adopt the SIM900Awireless communicationmodule to transfer the GPRS data; MMI realized the screen touch operation through theSSD1963Driver, also transplanted theμC/OS+GUI making the operation more simply andunderstandably. This system was much convenience for more rural people to operate in dailywork and with more application in agricultural construction in the future.The wireless acquisition system mention in this paper could realize mobile operationconvenient and efficiency, the response time less than20s for data transmission, this would notonly reduce the cost but also improve the system reliability, meanwhile, the system maintenancewould become much easier and the acquisition system real-time would be much bettercomparing to the traditional collection terminal. It could be meet the requirement of monitoringin outdoor hostile environment for farmers. |
