Fault detection method and device, detection system and computer readable storage medium

Abstract

The invention relates to the technical field of fault detection, and discloses a method for fault detection, which comprises the following steps: acquiring a plurality of sampling values in a data bit under the condition that a control module receives an interference signal; acquiring a current working mode of the controlled device under the condition that the unequal sampling values exist; and obtaining a judgment result about whether the current working mode is normal. And sending a high-frequency analog interference signal to the control module through the interference module. And under the condition that unequal sampling values exist in the data bits, determining that the data received by the control module is interference data. And through the current working mode of the controlled device, whether the controlled device can operate normally under the current interference signal is determined. Therefore, the probability of fault reproduction is improved through the high-frequency analog interference signal, so that the time required for fault positioning is shortened, and the detection efficiency of the system is improved. The invention further discloses a fault detection device, a fault detection system and a computer readable storage medium.
