Abstract

The invention relates to a disconnection control device for an electric connector for satellite testing and launching. The electric connector includes a detachment electric connector and a separationelectric connector. The disconnection control device comprises an industrial control computer, an adapter cable, a satellite-ground long cable, program-controlled power supplies, a photoelectric converter, an optical fiber, a switch, a switching module, a signal conditioning module, a multiplexer module, a multimeter module, an analog acquisition module, a state acquisition module, control software, a general control terminal computer, a test server and a monitoring terminal computer. The disconnection control device realizes adaptive control for detachment electric connector detachment control and separation electric connector separation control, performs statistical analysis on test data such as the voltage, current, disconnecting time and disconnecting times during detachment and separation and gives the performance variation trend of the electric connector in the form of tables and curves; and meanwhile, the disconnection control device has anti-misoperation prevention measures andredundant design means, and improves the safety, reliability and fault-tolerance of thedetachment electric connector detachment control and the separation electric connector separation control.

Description

technical field

[0001] The invention relates to a high-reliability disconnection control device for a shedding electrical connector and a separated electrical connector for satellite testing and launching. Background technique

[0002] The satellite drop-off electrical connector is used for connecting or disconnecting the satellite and ground power supply and distribution equipment; the separating electrical connector is used for connecting or disconnecting the satellite and the launch vehicle. Whether the satellite disconnection electrical connector can fall off normally will affect the timing of the satellite launch; whether the satellite separation electrical connector can be separated normally is related to the success or failure of the satellite launch mission. Therefore, it is necessary to carry out high-reliability disconnection control on the satellite shedding electrical connector and the separation electrical connector, so as to realize the normal shedding of the s...
