Problems solved by technology

The wrong grounding wire of the power line for power supply of airborne equipment will cause the aircraft power supply equipment to be damaged due to overcurrent, and the misoperation of airborne equipment will cause damage due to the power line connected to the data line or control line of the airborne equipment. Cable conduction problems such as some circuits of the equipment occur from time to time, so the completion of the cable conduction and insulation characteristic test before the power-on inspection of the airborne equipment is a must-complete production process

Embodiment 1

[0034] Take the test of the conduction performance between XA1 and XA2 of the XA aircraft wiring harness as an example to illustrate:

[0035] 1. See figure 1 , Run the continuity test program on the display and control device 1, the display and control device 1 sends the harness continuity test command to the harness analyzer 2, and the harness analyzer 2 outputs a constant current and the address data of the tested harness after running the continuity test command Send to the address module 3; the address module 3 sends the constant current and address data to the tested wiring harness 6 through the interface adapter device 4 and the adapter cable 5;

[0036] 2. figure 1 When the address module 3 in the device sends the constant current and address data to the interface adapter 4, the constant current from figure 2 The M1 address module in is reached via the J1 harness, XA1 connector figure 1 In the tested wire harness 6, after the test is completed, the feedback current...

Embodiment 2

[0040]Take the insulation performance between X1 and X2 of the XJ-type aircraft wiring harness as an example to illustrate:

[0041] 1. See figure 1 , Run the insulation test program on the display and control device 1, the display and control device 1 sends the wire harness insulation test command to the wire harness analyzer 2, and the wire harness analyzer 2 outputs a constant voltage after running the insulation test command and sends the address data of the tested wire harness to the address Module 3; the address module 3 sends the constant voltage and address data to the tested wiring harness 6 through the interface switching device 4 and the switching cable 5;

[0042] 2. figure 1 When the address module 3 in the device sends the constant voltage and address data to the interface conversion device 4, the constant voltage is from figure 2 The M1 address module in is reached via the J1 harness, X1 connector figure 1 In the tested wire harness 6, after the test is comp...

Abstract

The invention provides a standing helicopter cable in-situ test platform, which comprises a display control device (1), a wire harness analyzer (2), an address module (3), an interface switching device (4) and a switching cable (5), wherein the display control device (1) is connected with the wire harness analyzer (2), the wire harness analyzer (2) is connected with the address module (3), the address module (3) is connected with the interface switching device (4), the interface switching device (4) is connected with the switching cable (5), the switching cable (5) is connected with a tested wire harness (6), the address module (3) comprises a plurality of switches and connectors, each switch and each connector pin are endowed with corresponding address codes, the interface switching device (4) is used for matching the address of the address module (3) with switching cables (5) of various types of machines to realize an address extension function, and the pins of the connector of the interface switching device (4) have the same address code as the switch and the connector in the address module (3).

Description

technical field [0001] The invention belongs to the cable digital conduction technology, and relates to a station-type helicopter cable in-situ testing platform. Background technique [0002] The connection of the helicopter on-board cable harness, the insulation of the relative ground wire, and the insulation characteristics between the cables are all closely related to the safety of the power-on of the on-board equipment. The wrong grounding wire of the power line for power supply of airborne equipment will cause the aircraft power supply equipment to be damaged due to overcurrent, and the misoperation of airborne equipment will cause damage due to the power line connected to the data line or control line of the airborne equipment. Cable conduction problems such as some circuits of the equipment occur from time to time, so it is a must-complete production process to complete the test of the conduction and insulation characteristics of the cable before the power-on inspecti...
