无线通信系统

1、系统由一个主站，多个从站组成。主站以轮询方式收集从站的数据，每次传输一组仿真数据。

2、从站有两组数字信号。从站传输哪一组数据由主站决定。

3、设计制作无线半双工收发单元，其工作频率（400-500）MHz中自行选择，各收发单元工作频率的相对准确性（以主站工作频率为基准）优于10-4。所有收发单元的发射功率不大于1w。

4、主从站收发天线长度 1m，垂直放置。

5、主站能实时显示发送数据的从站好及其数据。从站能实时显示本站发送给主站的数据；从站采用电池供电。

-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
