Abstract：Aiming at the low efficiency 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 show that 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.
