Description
technical field [0001] The invention relates to the field of fault monitoring of signal acquisition modules, in particular to a system and method for automatically monitoring faults of signal acquisition modules. Background technique [0002] At present, the signal acquisition device is widely used, and plays a vital role in the circuit. When it is necessary to use multiple signal acquisition devices to collect signals, if a certain signal acquisition device occurs, the fault of a certain signal can only be judged through the fault phenomenon, and the signal acquisition device corresponding to the fault cannot be known. Offline after power failure, and disassemble the hardware to check one by one, the workload of troubleshooting is heavy, and the maintenance efficiency is low. Contents of the invention [0003] In view of the defects in the prior art, the purpose of the present invention is to provide a system and method for automatically monitoring the failure of the sig...
