遵循AISG2.0协议的时分复用塔顶放大器控制单元设计
|
摘要
根据AISG2.0协议对时分复用塔顶放大器(Time Division Duplex-Tower Mounted Amplifier,TDD-TMA)的控制性能要求,提出了一种TMA嵌入式控制单元设计方案。设计了基于对数放大器和射频开关的OOK通信模块,有效解决了发送信号绕回到接收端的问题。设计了基于电流负反馈的可配置式电流告警电路,实现了告警电流的精确控制。给出了AISG协议栈和TMA故障检测与处理模块的软件实现方法。测试结果表明,该设计方案通信及控制性能符合AISG协议要求,状态监控功能完善,且当AISG通信故障时具备自动切换到电流告警模式的功能。
According to control performance requirement of Antenna Interface Standards Group(AISG) 2.0 protocol to Time Division Duplex-Tower Mounted Amplifier(TDD-TMA), a design scheme of TMA control unit was presented. An on-off keying(OOK) communication module employing logarithmic amplifier and RF switch were designed, and they effectively solve the problem of sending signal loop back to the receiver. One configurable current-alarm circuit based on current negative feedback was designed to provide exact control on alarm-current. AISG protocol stack design, TMA fault detection and processing module were also given respectively. The test results show that this design scheme matches the communication and control requirement of AISG protocol well, presents sophisticated state monitoring function, and also features its current-alarm function when AISG communication failure occurs.
