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 method for detecting a power supply interface for comprehensive testing of small satellites. The specific steps are as follows: the first step: connecting a self-test cable and an extension cable; the second step: switching the system to a self-test mode; the third step: standardizing Voltage measurement and data comparison; Step 4: Connect the cable to be tested to the system host; Step 5: Power on the entire satellite; Step 6: Switch the system to the test mode; Step 7: Measure the voltage of the cable to be tested on the satellite ; Step 8: Interpretation of measurement data. The invention optimizes the traditional cable testing method, greatly improves the measurement of the power supply voltage on the satellite and the recording and interpretation of the test data and the traditional manual measurement method. Improve test efficiency.

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...
