Portable aviation cable fault test system

Abstract

The invention discloses a portable aviation cable fault test system comprising a host and an adapter cable, an intelligent shorting module and a remote control work station which are connected with the host. The host is provided with a main control panel, a touch control human-computer interaction module, a test mode switching and A/D acquisition board, an open circuit/short circuit test module, a high-precision TDR fault locating module, an element parameter test module and a digital channel switching module. The main control panel receives the operation instruction of the user and the remote control work station to control all the modules to perform measurement operation. The human-computer interaction module and the test mode switching and A/D acquisition board are connected with the main control panel. The open circuit/short circuit test module, the fault locating module and the element parameter test module are connected with the test mode switching and A/D acquisition board. The channel switching module is connected with the open circuit/short circuit test module, the fault locating module and the element parameter test module. The adapter cable is connected with the digital channel switching module of the host.

Description

technical field [0001] The invention relates to the field of cable testing, in particular to a portable aviation cable fault testing system. Background technique [0002] The aviation cable is the nervous system of the aircraft, which transmits power supply, transmits control signals and data information to the aircraft's electrical, avionics, communication, control and other systems. In aircraft maintenance, accurate detection of aviation cable faults is of great significance to ensure aircraft quality and flight safety. [0003] The feedback information from the survey shows that during the assembly and commissioning of various aircraft (such as helicopters, fighter jets, etc.) and the use and maintenance of troops, there will be problems with the need to test the cables on the aircraft due to the abnormal operation of the airborne equipment. The current practice is usually to use an ordinary digital multimeter, connect a very long wire, and test each terminal point at bo...

AI Technical Summary

Problems solved by technology

The current practice is usually to use an ordinary digital multimeter, connect a very long wire, and test each terminal point at both ends of the cable by two testers. This method has many inconveniences:

[0004] 1) The distance between the two ends of the tested cable is likely to be far away, and it is very inconvenient to pull a long wire during the test;

[0005] 2) Two people must cooperate during the test, and they must communicate and coordinate with each other. The long distance makes communication inconvenient, especially when the ambient noise is high;

[0006] 3) Many of the tested cable heads are in a relatively dark and narrow space, and the testers "drill" to find small cable nodes in it, which is inaccurate and easy to fatigue;

[0007] 4) It needs to be tested point by point, and each point needs to be determined by two people, so the test speed is very slow;

[0008] 5) The test items are not comprehensive, only the on-off test can be performed, and the failures such as on-resistance, insulation resistance, withstand voltage and pin shrinkage cannot be tested
