Problems solved by technology

The traditional test method is to use a multimeter and an insulation meter to manually test the cable network point-to-point directly. This method has low test efficiency and low measurement accuracy, and there is a risk of physical damage to the cable network during the test. Obviously, manual tes

Abstract

The invention provides a cable net conduction insulation automatic testing system based on PXI. The cable net conduction insulation automatic testing system comprises a portable PXI cabinet combination, a relay switching combination, a programmed control insulation tester, a printer, and a testing cable. The portable PXI cabinet combination comprises a PXI embedded type controller, multiplexer modules, relay driving modules, a digital multimeter module, and a keyboard display combination. The relay switching combination comprises a high voltage resistant relay board, a power supply module, and a testing cable switching box. The PXI embedded type controller is the control center of the whole automatic testing system, and switching of conduction to-be-tested points is realized by controlling two multiplexer modules, and the digital multimeter module is used to realize cable net passive conduction testing. The three relay driving modules and the one multiplexer module are used to realize switching of insulation to-be-tested points, and the programmed control insulation tester is used to realize a cable net insulation testing function.

Description

technical field [0001] The patent of the invention relates to a PXI-based automatic test system for cable network continuity and insulation. It adopts a modular design concept and has the advantages of good work stability, high test efficiency, high reliability, and good scalability. The automatic test of source continuity test and insulation test has effectively improved the automatic test level and test efficiency of the cable network test, and the efficiency of the traditional test method has been increased by more than 300%. Background technique [0002] Before the cable net leaves the factory, during the cable assembly process and after assembly, it is necessary to conduct a passive continuity test and an insulation test on the cable net to verify whether its electrical performance is qualified. The traditional test method is to use a multimeter and an insulation meter to manually test the cable network point-to-point directly. This method has low test efficiency and lo...
