Problems solved by technology

However, the system can only feedback whether the working status is abnormal at that moment, and cannot locate and diagnose the abnormality, and cannot establish an effective and rapid processing mechanism for serious faults. In addition, the automatic interpretation method of the system has not been specifically explained

[0087]

[0088]

[0089]

[0090] The software implementation of the method is loaded in the computer, connected to the current test network, receiving and analyzing the front-end multicast telemetry frame and the remote control command sent by the MTP.

[0091] The solar array simulator is powered up, the uplink and downlink channel adjustment of the satellite is completed, and the satellite reaches the initial power-on state after the satellite battery is connected. The ground test system sends a remote control command to the satellite power supply subsystem through the console, and the satellite power supply subsystem receives the remote control command. After that, send the telemetry data to the ground test subsystem;

[0092] The software implementation of this method receives the real-time dow...

Embodiment 2

[0098] In a certain test of the same type of satellite, the test knowledge base is consistent with that of Embodiment 1, and will not be repeated here. Analyze the relevant telemetry parameters of the power pack, and obtain the initial telemetry values ​​as shown in Table 3.

Abstract

Disclosed is a satellite power supply health condition tracking and detecting method based on intelligent interpretation. A basic test knowledge base is firstly built, telemetry parameters of a power supply subsystem are collected, relevant criteria are summarized, the telemetry parameters are collected and processed, initial health condition checking is completed, health condition checking is implemented, and finally fault judgment and emergency operation processing are carried out according to the checking result. The power supply safety in the satellite testing process is monitored in real time, faults occurring in a test are analyzed and located, the relevant operation of alarming and power failures is executed in an emergency, misjudgment and wrong judgment of manual monitoring are avoided, fault losses are reduced to the greatest degree, and reliability and safety in the testing process are improved.

Description

technical field [0001] The invention relates to a method for tracking and detecting the health status of a satellite power supply, in particular to a method for tracking and detecting the health status of a satellite power supply based on intelligent interpretation, which is applicable to the satellite AIT testing stage. Background technique [0002] During the factory test phase of the satellite, in order to timely and effectively discover potential failures and hidden dangers, it is necessary to fully test and verify its various performance indicators. Among them, the satellite power system is of great significance in the type test work, which is directly related to the safety of satellite power consumption, and affects the life of the satellite in orbit and the realization of missions. At present, in the satellite comprehensive test, there is no unified standard for real-time tracking and detection of power supply health status. The interpretation and monitoring of teleme...
