Description: a wireless communication system, the system consists of a master station, a number of components from the station. Polling stations in the main collection of data from each group a transmission simulation data. 2, only two points from the digital signal. Transmission from which data from the main points decision. 3 and the design of wireless half-duplex transceiver modules, its frequency (400-500) MHz which to choose, the frequency transceiver modules relative accuracy (to the main points of the baseline frequency) is better than 10-4. All transceiver module fired power less than a w. 4, the main station transceivers from the antenna length of 1m, placed vertically. 5, the main station can send real-time display of data from the good points and its data. From the station can send real-tim
