Fault diagnosis device and method for remote sensing satellite receiving system

Abstract

The invention provides a fault diagnosis device and method for a remote sensing satellite receiving system. The method includes the steps that state information of preset monitoring points in devices of the remote sensing satellite receiving system is acquired; parameters of the devices in a servo system, a tracking channel and a data receiving channel of the remote sensing satellite receiving system are set according to a test type, and then an automatic test is finished; various kinds of task information recorded through the remote sensing satellite receiving system in real time in the data receiving task execution process is acquired; according to the acquired state information of the monitoring points, the automatic test information and the various kinds of task information, fault diagnosis of the remote sensing satellite receiving system is finished by establishing a fault diagnosis model and a fault diagnosis expert system. By the adoption of the device and method, fault information in the system can be acquired, found and reported instantaneously, the system fault model is established, and quick and automatic fault diagnosis of the remote sensing satellite receiving system is achieved.

Description

technical field [0001] The invention relates to the technical field of fault diagnosis, and more specifically, to a fault diagnosis device and a fault diagnosis method for a remote sensing satellite receiving system. Background technique [0002] As more and more remote sensing satellites are launched into the sky, the remote sensing satellite ground station undertakes more and more remote sensing satellite data receiving tasks, which puts forward higher requirements for the trouble-free and stable operation of the remote sensing satellite receiving system of the receiving station. [0003] Due to the complex structure of the remote sensing satellite receiving system and the tight coupling between the equipment in the system, as the automation of the operation becomes higher and higher, a fault in the system may cause a series of chain reactions, resulting in the system not working normally and affecting the satellite data. Receipt of resources. On the other hand, at presen...
