Problems solved by technology
However, the internal self-test data of the transceiver module is unreliable. When the output of a certain indicator module is 1, the corresponding equipment part may not be faulty, and when all the indicator modules are 0, it does not necessarily mean that the transceiver module is not faulty. Therefore, there is a problem that the detection accuracy is not high and inaccurate

The invention relates to a fault detection method and system for a transceiver module of a communication extension, using the data of the internal self-test as a preliminary judgment basis, and then testing the data test points of the transmitting data encoding module and the receiving data decoding module connected with the transceiver module , through the performance test and fault diagnosis of the transmitting data encoding module and the receiving data decoding module, as the indirect data for judging the failure of the transceiver module, and comparing and analyzing with the data of the internal self-test, intuitively judge the failure mode of the transceiver module and complete the fault Positioning improves the fault diagnosis rate and fault location accuracy.
Description
technical field [0001] The invention relates to the field of communication extension performance testing and fault diagnosis, in particular to a fault detection method and system for a communication extension transceiver module. Background technique [0002] The original transceiver module of the radar communication extension can only perform fault judgment and location based on the output data of the internal self-test, which has the problems of low fault diagnosis rate and low fault location accuracy. The built-in self-test refers to the data that has been embedded in the equipment and has fault prompts on the outside when the equipment is produced. Self-inspection is a kind of inspection method that the equipment will run normally and automatically inside when it is working normally, and belongs to the existing technical means. The self-test data of the transceiver module is mainly the output of the three indicating modules. There are two types of outputs from indicator...
