The invention relates to an II-type collector fault disassembling, sorting and detecting device which comprises a test board and a control cabinet connected with the test board, and the test board comprises a clock test module, a 485 communication test module, an infrared communication test module, a carrier test module and a test meter position system. The device has the advantages that the II-type collectors are uniformly mounted on the test board through the test meter position system, the control cabinet sets test parameters, carrier communication and micropower communication tests of thetype-II collector are tested through configuration of the carrier test module. Then, accurate test clock output comparison sources are provided for the testboard through clock test modules arranged onthe testboard respectively. The 485 communication test module provides an analog 485 communication test, and the infrared communication test module completes an infrared communication test function,so that online batch detection of various fault types of the fault collector is realized, the overall detection efficiency is improved, the cost can be greatly saved, and the waste of resources is avoided.
