Embodiment Construction

[0048] The present invention will be described in detail below with reference to specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that, for those skilled in the art, several changes and improvements can be made without departing from the inventive concept. These all belong to the protection scope of the present invention.

[0049] like figure 1 , a satellite power supply shunt abnormal detection method based on power supply sequence analysis, comprising the following steps:

[0050] Step S1: Receive satellite-to-ground telemetry data in real time, and obtain all the voltage values ​​of the sub-arrays of the satellite power supply. During the ground test, the voltage of the sub-arrays can be obtained through the telemetry of the ground solar simulation array equipment and satellite telemetry. When the satellite is in orbit, the vol...

Abstract

The present invention provides a method and system for detecting abnormality of satellite power supply shunt based on power supply sequence analysis, comprising: step S1: receiving in real time the telemetry of the sub-array voltage of each satellite power supply, and grouping the satellite power supply sub-arrays into groups according to the shunt control type , carry out the power supply sequence shunt detection; Step S2: carry out the sequence monotonicity test for the S3R type power supply array, and judge whether the shunt is normal; Step S3: carry out the sequence ascending and descending sequence test for the S4R type power supply charging array, and judge whether the shunt is normal; Step S4 : Carry out sequence monotonicity test for the hybrid power supply charging array to determine whether the shunt is normal; Step S5: If all kinds of power supply sequences are tested normally and the bus voltage is stable, the shunt control is normal, otherwise the shunt is abnormal and an error is reported; continue to receive the next Take telemetry data and continue to cyclically monitor the power shunt status. The invention has good engineering application value.

Description

technical field [0001] The present invention relates, in particular, to a method and system for detecting abnormality of satellite power shunting based on power supply sequence analysis. Background technique [0002] The satellite power supply system provides energy supply for the work of various systems of the satellite, which directly affects the working life of the satellite in orbit. The present invention receives real-time telemetry of the sub-array voltage of each satellite power supply, and groups the satellite power supply sub-arrays according to the shunt control type, and performs the shunt detection of the power supply sequence; The shunt control is normal, otherwise the shunt abnormality will report an error; continue to receive the next shot of telemetry data, continue to cyclically monitor the power shunt status, so as to achieve real-time and efficient detection of power supply abnormalities, which has good engineering application value. [0003] Existing pap...
