摘　　要：针对天线线上设备(ALD)安装调试工具普遍存在效率低下、操作繁琐的问题,提出了一种符合AISG协议要求的便携式ALD手持控制器设计方案.该方案采用基于对数放大器的检波方法实现了接收灵敏度可调节的OOK通信电路,分析了AISG协议的设备扫描方式,设计了一种区分ALD设备类型的四叉树扫描算法,实现了对AISG总线上不同类型ALD设备的快速识别.结果表明,本设计方案符合AISG协议规范要求,控制功能完善,具有协议兼容性好和扫描速度快的优点.Aiming at the lowefficiency and complicated operation problems commonly existing in the current installation and debugging tools of antenna line device（ ALD）,a portable ALD control equipment design scheme conforming to AISG protocol was proposed. A demodulation method based on the logarithmic amplifier was employed to realize the OOK communication circuit with adjustable receiving sensitivity. The device scanning method of AISG protocol was analyzed,and a quaternary tree scanning algorithm for distinguishing the ALD device type was designed,which could realize the rapid identification of ALD devices with different types on the AISG bus. The results showthat the proposed design scheme accords with the specification requirement of AISG protocol,exhibits the impeccable control function,and also has the advantages of good protocol compatibility and high device scanning speed.
