Abstract
本发明提供一种油气井地面无线测试系统和方法，系统由N台无线采集器、多台无线中继器、一台集中接收器和一台控制终端四部分组成。其中各台无线采集器与无线中继器之间、以及无线中继器与集中接收器之间由无线电连接，构成多跳的树形网络拓扑结构，集中接收器与控制终端之间是短距离的有线连接。由于采集器与中继器以及中继器与集中接收器之间采用无线传输，不再需要布置大量的线缆，使用和维护都十分方便，并且不需要长距离的有线传输，传感器的输出不需要大电流的变送电路来实现长距离的信号驱动，功耗大幅度降低；同时由于无线采集器采用周期性休眠/唤醒机制，即只在数据传输时才需要启动射频电路，而发送的数据时间非常短，因此只需要使用普通锂电池供电就可以，这样就大大地降低了供电系统的安装成本和难度，且也大大降低了系统的运行成本。
