Distributed wire harness test system and method based on SCTP

Abstract

The invention relates to the field of wire harness testing, in particular to a distributed wire harness test system and method based on SCTP, the system comprises communication and measurement, the measurement part comprises LCR measurement, low resistance measurement, insulation resistance measurement, direct current withstand voltage measurement, alternating current withstand voltage measurement, diode withstand voltage measurement and on-off test, the system supports two-wire system and four-wire system tests, and the test accuracy can reach 10 micromhos. The system adopts a distributed layout, and can be freely combined and arranged according to the distribution of test points of the whole aircraft during large-range multi-point measurement; under the condition that the number of test points is large and the distribution range is large, a tester does not need to run back and forth to read wire harness test data, and the test data of all the test points can be read at the host end at a time through the connection of the test host and the slave; ethernet communication is used, an SCTP protocol is used, and distributed measurement and transmission of a large amount of test data can be carried out. When the system and the method are applied to wire harness testing, detection can be completed more quickly.

Description

Technical field [0001] The present invention relates to the field of harness tests, and more particularly to a SCTP-based distributed harness test system and method. Background technique [0002] In recent years, as the safety requirements of public facilities such as plane subway high-speed rail are continuously improved, the requirements for speed accuracy of the wire harness test are constantly increasing, and the cable of large equipment is distributed in all parts of the fuselage, so the number of cable measurements is huge and spread all over. At the whole body. In response to this feature, a distributed test scheme is used instead of traditional centralized measurements. [0003] Since the test speed is required, a large amount of measurement data and control data transmission are required. At present, the current test method performs a slower speed of detection when the data transmission of the harness test is slow, and the demand for fast detection cannot be met. Invent...

Problems solved by technology

[0004] The purpose of the present invention is to provide a distributed wire harness testing system and method based on SCTP, aiming to solve the problem in the prior art that the test speed is fast and a large amount of measurement data and control data transmission are required during the wire harness test. When dealing with the transmission of a large amount of test data in the wiring harness test, the detection speed is slow, which cannot meet the technical problems of rapid detection.
