Cable testing system applied to minisatellite

Abstract

The invention discloses a cable testing system applied to a minisatellite. The cable testing system comprises a cable adapter module, a channel control module, a conduction testing module, an insulation testing module and a system self-inspection module. Cables to be tested with different port types are connected to internal channels of the system through the cable adapter module, the channel control module controls connection and disconnection of the internal channels, the conduction testing module measures conduction resistance value among the channels, the insulation testing module measures insulation resistance value among the channels, and the system self-inspection module inspects and calibrates the system. The cable testing system solves the problems of low conduction insulation testing efficiency, poor accuracy, long period and high strength in low-frequency cables on satellites and ground testing low-frequency cables, quick testing of conduction insulation characteristics of the cables can be realized, and the cable testing system is applicable to the low-frequency cables on the satellites and the ground testing low-frequency cables.

Description

technical field [0001] The invention relates to a cable test system applied to small satellites, which can be applied to the conduction and insulation characteristic test of low-frequency cables on small satellites and ground test low-frequency cables. Background technique [0002] Low-frequency cables are widely used basic materials in the aerospace field. The detection of cable wiring correctness, on-off status, and conduction and insulation performance is an important item in satellite testing. However, the different functional uses of cables, the number of cable cores, and the types of connector interfaces make cable inspection a work with high safety requirements, cumbersome inspection items, and time-consuming and labor-intensive work. In the small satellite industry, the cable detection method has not been greatly developed. The measurement of the conduction characteristics is generally measured point by point with a multimeter, and the measurement of the insulation c...
