Embodiment Construction

[0020] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0021] Such as figure 1 As shown, a power supply interface detection method for comprehensive testing of small satellites, the specific steps are:

[0022] Step 1: Connect the self-test cable and extension cable: the electrical connector interface array at one end of the cable transfer box is connected to the self-test interface at one end of the main cabinet of the system through the self-test cable, and the extension cable interface at the other end of the cable transfer box is extended The cable is connected to the extension cable interface at the other end of the system host, and the internal channel of the system forms a closed loop;

[0023] The cable transfer box includes an interface array, a signal conditioning board, a sliding baffle and an extension cable interface. Two sets of electrical connector interface arrays are installed on the front, which are co...

Abstract

The invention discloses a power supply interface detection method for a minisatellite comprehensive test. The power supply interface detection method includes 1, connecting a self-checking cable and an extension cable; 2, switching a system to a self-checking mode; 3, measuring standard voltage and performing data comparison; 4, connecting a cable to be detected with a system main unit; 5, powering up a minisatellite; 6, switching the system to a test mode; 7, measuring voltage of a cable to be detected on the minisatellite; 8, interpreting measuring data. The power supply interface detection method has the advantages that the traditional cable detection method is modified; compared with the traditional manual measurement method, the method of measuring minisatellite supply voltage and recording and interpreting the measurement data is greatly improved; during the minisatellite power supply interface detection, test process is simplified, and test efficiency is improved.

Description

technical field [0001] The invention relates to a power supply interface detection method for small satellite comprehensive test, which can be applied to the whole satellite power supply interface inspection item in the small satellite comprehensive test in the aerospace field. Background technique [0002] With the rapid development of the aerospace field, the complexity of satellite loads continues to increase, and the on-board power supply system has become more diversified, such as wider voltage ranges, more types of cable interfaces, and more complex cable interconnections. The power supply system is an extremely important part of the entire satellite. If there is a problem with the power supply, the satellite will not be able to operate normally, and the on-board subsystem will be burned out, or even completely scrapped. Therefore, the voltage correctness detection of the interface of the power supply and distribution subsystem on the star, referred to as the power sup...
