High-protection distribution box fault detection method and device

Abstract

The invention discloses a high-protection distribution box fault detection method, which comprises the steps that a distribution box circuit interface transmits a fault signal to a fault detection input end, the fault detection input end transmits the fault signal to a fault signal processing module, and the fault signal processing module performs preliminary processing on the fault signal; the fault signal processing module transmits the processed signal to a fault adjustment generation module, and the fault adjustment generation module adjusts a generation scheme after fault detection; and the adjusted generation scheme is transmitted to the distribution box circuit interface through a fault adjustment scheme output end. In the process, an analog-digital module receives output of the fault signal processing module and transmits the output to the processing module, the processing module sends a command to the feedback module after recognition processing, and the feedback module generates a feedback signal, transmits the feedback signal to the fault signal processing module and reconfigures the fault signal processing module. The invention further discloses a high-protection distribution box fault detection device applying the method.

Description

technical field [0001] The invention relates to the field of distribution boxes, in particular to a fault detection method and device for a high-protection distribution box. Background technique [0002] Traditional distribution box fault detection methods use a single solidified circuit detection, for example, a distribution box-based fault detection method and fault detection device disclosed in Chinese invention patent application CN201910908494.6, the method is mainly to obtain power distribution The image information of the electronic mechanism inside the box and the auxiliary mechanism of the electronic mechanism; based on the image information of the electronic mechanism and the auxiliary mechanism, it is judged whether the electronic mechanism and the auxiliary mechanism are abnormal; When an abnormality occurs in the mechanism and / or the auxiliary mechanism, an abnormal alarm prompt is given. The detection device includes an acquisition unit for acquiring image inf...

Problems solved by technology

The technology disclosed in this patent is a relatively common technology in the prior art. In actual detection, such technologies often encounter two problems. Problem 1 is that the fault circuit may affect the performance of the detection circuit, because the fault type of the fault circuit When the fault circuit is abnormal, the detection circuit electrically connected to it may also be abnormal and affect the performance of the detection circuit. Problem 2 is that the fault of the fault circuit is diverse and unpredictable. The traditional detection circuit is relatively solid and at least in the configuration The circuit itself on the detection circuit has been solidified, and the solidified detection circuit is essentially unable to meet the needs of detection diversity and unpredictability
