Problems solved by technology

This kind of discrete measuring instrument is not easy to move due to the large number of associated equipment, and cannot meet the diagnostic testing requirements of the commissioning workshop, troubleshooting site, and external test field.
Not only can it not be used as a diagnostic test equipment for cable harness conduction interference, but it may also bring new unnecessary interference to electronic products

Abstract

The invention discloses an on-site diagnosis and test device and method for cable bunch conduction interference. The device comprises a signal generation unit, a signal amplification unit, a frequencycollection unit, a control unit and a display unit, wherein the signal generation unit is used for forming an interference signal; the signal amplification unit is used for amplifying the interference signal and injecting the amplified interference signal into an electronic equipment cable; the frequency collection unit is used for detecting a detection signal of the electronic equipment cable through a collection probe when the interference signal is injected; the control unit is used for obtaining an interference detection result of the electronic equipment cable according to the detectionsignal collected by the frequency collection unit and transmitting the interference detection result to the display unit; the display unit is used for displaying the interference detection result transmitted by the control unit to a user. The on-site diagnosis and test device and method for the cable bunch conduction interference can achieve the mobility and portability of on-site electromagneticcompatibility diagnostic tests.

Description

technical field [0001] The invention relates to the field of cable bundle conduction detection signal measurement. More specifically, it relates to a device and method for on-site diagnosis and testing of cable bundle conduction interference. Background technique [0002] The formation of electromagnetic interference requires the joint action of three factors: interference source, coupling path and sensitive equipment, that is, the three-element principle of electromagnetic interference. Electromagnetic interference is divided into radiated interference and conducted interference due to different coupling methods. Conducted interference must have a complete line connection between the interference source and sensitive equipment, and the detection signal is transmitted to the sensitive equipment along the cable to generate interference. Among them, the cable, as an important component of the electronic system, is one of the main ways for the electromagnetic pulse energy to ...
