Device and method for fault detection of equipment line

Abstract

The invention discloses a device line fault detection device, which includes a sending module for generating an initial code and converting the initial code and sending it to the line to be detected and a judgment module, and a receiving module for receiving the fault transmitted by the line to be detected The initial code converts the signal, and generates a verification code, and a judgment module, which is used to receive the initial code and verification code information, and judges whether the verification code and the initial code are consistent, and a switch module, which is used to control the on-off state of the entire detection device, and The protection module is used for current limiting protection and static electricity removal of the whole device; the advantage of the present invention is that the internal circuits of the equipment can be detected separately, and whether the condition of each section of the circuit is checked one by one, which effectively improves the detection accuracy and does not require Waiting for the start-up of the electrical appliances and the debugging of various functions reduces the detection time and improves the detection efficiency.

Description

technical field [0001] The invention relates to the technical field of equipment line testing, in particular to an equipment line fault detection device and method. Background technique [0002] All electrical appliances or accessories of electrical appliances need to be tested for various performances after they are processed on the production line, the most important of which is the circuit inspection of electrical appliances. At present, the detection of electrical circuits is mostly carried out on the assembly line. The assembly line is connected to the detection station, and then the detection is carried out by the corresponding detection device. [0003] The functions of these detection devices on the market are relatively single, basically they just provide the total power for electrical appliances, and then observe whether the electrical appliances can operate normally. There are many uncertain factors in this detection method, it is difficult to detect whether the ...
