Embodiment Construction
[0040] The preferred embodiments of the present invention are given below in conjunction with the accompanying drawings to describe the technical solution of the present invention in detail.
[0041] Such as Figure 1 to Figure 2 Shown, the satellite fault diagnosis method that the present invention realizes based on software comprises the following steps:
[0042] Step 1, the ground station sends a note number containing fault diagnosis information to the satellite;
[0043] Step 2. The on-board computer software judges the legality of the received bets. If it is legal, go to step 3. Otherwise, discard the bets and do not process;
[0044] Step 3. The on-board computer software enters the fault diagnosis telemetry mode, and downloads the fault diagnosis package to the ground until the downloading of all fault diagnosis packages is completed;
[0045] Step 4. The on-board computer software exits the fault diagnosis mode and resumes the normal telemetry mode.
[0046] The fa...

The present invention discloses a satellite fault diagnosis method based on software. The method comprises the following steps: (1) a ground station sends injection parameter(s) containing fault diagnosis information to a satellite; (2) the on-board computer software performs legitimate judgment on the received injection parameter(s), if the injection parameter(s) are legitimate, the program enters step (3), otherwise the injection parameter(s) are abandoned and not treated; and (3) the on-board computer software enters a fault diagnosis telemetering mode and downwardly transmits fault diagnosis package(s) to the ground until the downward transmission of all the fault diagnosis package(s) is completed. The method does not affect the conventional telemetering mode, the detailed diagnosis onthe satellite working state or the fault is realized, the availability and maintainability of the satellite are improved significantly, and thus the method plays an active role in prolonging the lifeof the satellite. Moreover, the method is flexible and practical, and thus the method is easy to be applied in engineering practice.
Description
technical field [0001] The invention relates to a satellite fault diagnosis method, in particular to a software-based satellite fault diagnosis method. Background technique [0002] Satellites orbit the earth in low-to-medium orbits, high orbits, and even operate in deep space exploration environments. When satellites fail, the ground needs to find faults in time and take remedial measures to improve the availability of satellites and extend the life of satellites. The channel of interaction between the ground and the satellite includes two aspects of telemetry and remote control. Specifically, remote control means that the ground (which can be forwarded through relays) sends commands or notes to control the working status and behavior of the satellite; telemetry means that the satellite is downloaded to the ground and used by the ground to monitor the working status or fault diagnosis of the satellite. [0003] At present, the measurement and control function of the satell...
