Problems solved by technology
The above two methods mainly have the following problems: 1. The way of judging the power supply status through the unique upper and lower limit thresholds is too large and the granularity is too coarse, which can only reflect the basic functional status of the power supply; 2. It cannot be based on the actual status of the satellite. The working mode adjusts the discrimination range, and the specific power supply status of the power supply system cannot be distinguished, so the specific power supply status cannot be discriminated. 3. The fault mode can be inferred from the fault phenomenon. There are many times, the coverage requirements are very high, and there is often a problem that one fault phenomenon corresponds to multiple fault modes, and the fault mode cannot be accurately located; 4. It cannot predict the fault phenomenon of the satellite power supply status, and cannot diagnose the fault of the satellite in orbit Provide strong support and cannot buy time for ground fault handling

Embodiment
[0044] Embodiment: Taking a certain satellite as an example,
[0045] (1) According to the overall design status of the satellite, the flight attitude of the satellite includes two situations of normal flight and 20° sideways flight; the satellite load condition includes two situations of load standby (long-term) and load imaging (short-term); Period and shadow period; battery charging status includes two situations of charging and stop charging. One factor is extracted from each of the four categories and arranged and combined to form a combination as follows:
[0046] Combination 1: normal flight, load standby, light period, stop charging
[0047] Combination 2: normal flight, load imaging, light period, stop charging
[0048] Combination 3: normal flight, load standby, earth shadow period, stop charging
[0049] Combination 4: normal flight, load imaging, earth shadow period, stop charging
[0050] Combination 5: side swing 20° flight, load standby, light period, stop ch...

The invention discloses an automatic determination method of the satellite in-orbit power supply state. The method comprises the steps that an on-board computer acquires telemetry data of a satellite in a current flight state and generates a power supply mode word corresponding to the current flight state; the on-board computer sends the power supply mode word and the corresponding telemetry data to a ground test launch and control computer; the ground test launch and control computer identifies the power supply mode word and retrieves a pre-stored telemetry data criterion corresponding to the power supply mode word; and the ground test launch and control computer interprets the received telemetry data according to the telemetry data criterion to determine whether the current in-orbit power supply state of a satellite power supply is normal. The method of the invention realizes the objective of improving the efficiency and accuracy of determining the in-orbit power supply state of the satellite power supply.
Description
technical field [0001] The invention relates to the on-orbit operation and maintenance technology of spacecraft, in particular to an automatic judgment method for the on-orbit power supply status of satellites. Background technique [0002] Satellite power supply status discrimination is used to comprehensively and accurately grasp the working status of satellite power system during orbit. As a key subsystem of the whole satellite, the reliability of the satellite power system is directly related to the success or failure of the satellite mission. Therefore, the judgment of the satellite power supply status is one of the key links in the satellite's on-orbit operation and maintenance. [0003] The satellite power supply system mainly has three basic power supply modes: solar cell array alone power supply, battery pack alone power supply, and solar cell array and battery pack joint power supply. The working status of the specific power supply mode in each basic power supply m...
