Abstract

The invention relates to a self-checking method and a self-checking device of a vibrating table amplifier, which are used for performing self-checking on a vibrating table amplifier module mainly comprising a preposing module and a driving unit. The invention adopts as a scheme that the preposing module allocates addresses to each driving module in the driving unit and controls the turn-on and the turn-off of each driving module in an addressing mode; when the driving unit is abnormal, the preposing module selects more than one driving module, sends a detection signal to the driving module and receives a feedback signal sent by the driving module, and thereby judging the operating mode of the driving module by comparing the detection signal with the feedback signal; and then the preposing module selects other driving modules, and repeats the detection operation until all driving modules complete the self-checking, so that an operator can check and maintain the abnormal driving modules. The self-checking process of the vibrating table amplifier module can implement automation by utilizing the method and the device so as to reduce the workload of the operator and improve the working efficiency.
