Embodiment Construction

[0017] like figure 1 The schematic diagram of the system shown, the automatic detection system of the aircraft cable insertion status is composed of multiple distributed functional modules, including ground detection equipment, engineering telemetry interface unit, subsystem equipment manager and cable insertion status detection of K subsystem equipment Module, generally K is an integer greater than 2.

[0018] The ground detection equipment is equipped with dry batteries, and provides power supply for the detection system through the satellite-ground cable. The power supply objects include the satellite-ground interface module, control circuit, analog-to-digital conversion module, multi-way switch module, etc. contained in the engineering telemetry interface unit, and K sub-system equipment And the K+1 cable insertion detection modules included in the subsystem device manager. The power supply line is completely isolated from the on-board circuit.

[0019] The sub-system eq...

Abstract

The invention relates to an aircraft cable plugging connection state automatic detection system. The aircraft cable plugging connection state automatic detection system includes a ground detection equipment, an engineering telemetering interface unit, a subsystem equipment manager, subsystem equipment and a cable plugging connection state detection circuit; the ground detection equipment supplies power for the detection system through adopting a dry battery; the subsystem equipment and the subsystem equipment manager convert equipment cable plugging connection states into analog signals through the cable plugging connection state detection circuit; the subsystem equipment manager combines cable plugging connection state signals and subsystem telemetering signals of the subsystem equipment manager and the subsystem equipment into a telemetering output cable; the engineering telemetering interface unit converts the cable plugging connection state analog signals of the subsystem equipment and the subsystem equipment manager into digital signals sequentially; information is transmitted to the ground detection equipment through a satellite and ground cable; and the ground detection equipment automatically judges and reads the correctness of aircraft cable plugging connection states. The aircraft cable plugging connection state automatic detection system can automatically detect the aircraft cable plugging connection states with an aircraft unpowered.

Description

technical field [0001] The invention relates to an automatic detection system for the insertion state of aircraft cables, which is applicable to the field of aircraft system integration such as satellites, spaceships, and rockets, and is used for automatic detection of the correctness of the insertion states of aircraft cables except for bus cables, LVDS cables, and radio frequency cables. Background technique [0002] Aircraft development includes the initial sample stage and the positive sample stage. Due to differences in equipment maturity and development cycle, on-board equipment is installed in batches at each stage; Hardware and software upgrades; mechanical tests, thermal tests, special tests, etc. need to be arranged during the aircraft system testing process. The above reasons lead to frequent cable assembly operations during the aircraft system integration process. There are great differences in the plug-in status of the test cables under different test condition...
