Traditional manual testing is the main testing method, which has occupied the testing field for a long time. In the face of the rapid development of the main aviation industry and the accelerated industrialization process, the traditional manual inspection is no longer suitable for the large-scale testing needs in the development and production, and restricts the overall improvement of the inspection technology level. By analyzing the process and technical level of manual inspection, we can clearly understand its limitations. Control detection. The inspection needs to be carried out according to the drawing wiring table and wire number, which is very easy to cause missed and wrong measurements. The test is not comprehensive. On-resistance cannot be detected, components connected to the network, poor contact, unreliable contacts, and inductive effects cannot be detected. Insulation withstand voltage test. The limitation of the output voltage of the megohmmeter cannot meet the insulation resistance test of different automobile wiring harness designs, and the detection technical conditions and accuracy are limited; Pressure test, the test state cannot fully detect the withstand voltage characteristics. System software is the basis of test program design, providing test status display, test parameter setting and connector library establishment; the test program is established on the connection network of the tested chassis, and the running system software collects the connection relationship of the tested chassis and automatically generates Corresponding connection network. The adapter is the input and output of the test signal of the wiring harness tester and the interface of the chassis under test, and is the key to the test application. Consider scalability and practicality. The adaptation technology of the adapter determines the correct application of the wire harness tester, and directly determines the wiring harness tester and the tested
