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...

AI Technical Summary

Problems solved by technology

[0003] 1. The design of the satellite drop-off electrical connector drop-off control interface and the separation control interface of the separation electrical connector is generally a single control channel, lacking redundant control means, and the control reliability needs to be further improved;

[0004] 2. There is no test of the voltage and current when the connector is disconnected, especially the test of the drop-off and separation time, lack of statistical analysis of the test data, and it is difficult to find the trend of the performance change of the electrical connector;

[0005] 3. Lack of means to prevent misoperation, especially hardware link failure, automatic judgment of satellite flight plug mis-insertion or missed insertion, and separation control of electrical connector separation during satellite launch;

[0006] 4. Lack of adaptive control strategy, it is difficult to realize one-button automatic adaptive shedding and separation control;

[0007] 5. It is difficult to adapt to the remote control and remote real-time monitoring of the shedding process of the ultra-long-distance shedding electrical connector when the satellite is launched;

[0008] 6. Lack of storage of original test data, it is difficult to reproduce test data and process without distortion
