Problems solved by technology

[0004] At present, the satellite ground station has a monitoring system, which can quickly alarm and diagnose faults such as equipment shutdown and offline, but it cannot quickly locate or diagnose signal abnormalities caused by frequency drift and abnormal power amplifiers, and the occurrence of such faults will affect the data relay. Transmission or measurement and control tasks have an impact, therefore, an effective fault diagnosis method is urgently needed to solve such problems

Abstract

The invention provides a fault diagnosis method and device for a satellite ground station, and the method comprises the steps: receiving a downlink signal returned by a satellite communication device through a signal receiving link of the satellite ground station, and determining that the downlink signal is abnormal through a signal processing module, under the condition of determining that the signal transmitting link of the satellite ground station does not have a fault, a fault test signal can be simulated and generated through the signal simulation terminal, so that a fault diagnosis result of the signal receiving link is determined based on the fault test signal; besides, under the condition that the signal receiving link is not abnormal, loops can be constructed between different components in the signal transmitting link and the signal receiving link, so that fault diagnosis can be carried out on the different components in the signal transmitting link through the different loops.

Description

technical field [0001] The present application relates to the field of communication technology, and in particular to a fault diagnosis method and device for a satellite ground station, a computing device, and a computer-readable storage medium. Background technique [0002] Relay satellites are called "satellites of satellites", which can provide long-term data relay and measurement and control services for satellites, spacecraft, space laboratories and other spacecraft, greatly improve the use efficiency and emergency response capabilities of various satellites, and enable resource satellites , Environmental satellite and other data are downloaded in real time to win more early warning time for major natural disasters. The relay satellite communication system consists of spacecraft user terminals, relay satellites, satellite ground stations, etc. Among them, the satellite ground station is responsible for receiving data such as instructions from the control center and send...
