Distributed fault real-time monitoring and standby equipment switching method for satellite communication

Abstract

The invention relates to the field of satellite communication, discloses a distributed fault real-time monitoring and standby equipment switching method for satellite communication, and solves the problem of interruption of a satellite communication network caused by faults of node equipment in a large-scale satellite communication system. According to the technical scheme, the method is characterized by comprising the following steps that S1, a special management and control server is set for a satellite communication system to operate a management and control service system; S2, the management and control service system receives a fault alarm frame in the satellite network in real time through a narrowband control channel; S3, the management and control service system automatically completes state notification of the whole network equipment and the whole network service system; S4, the management and control service system generates network parameters for standby equipment to accessthe network; S5, the management and control service system automatically responds and sends a control frame switched to the standby equipment to complete troubleshooting according to the fault framesobtained actively and passively. According to the invention, real-time monitoring of equipment states of a central station and a gateway station can be realized, fault monitoring and switching are automatically completed by the management and control service system, the operation reliability of the equipment and the service system of the central station and the gateway station is greatly improved,and the problem of low efficiency of manual monitoring and switching is effectively solved at the same time.

Description

technical field [0001] The invention relates to the field of satellite communication, in particular to the automatic monitoring and control of multi-equipment and service system in a ground station based on satellite communication. Background technique [0002] my country is a country prone to natural disasters. Coupled with the large land area and the uncertainty of disaster occurrence, relevant units and personnel participate in rescue and disaster relief operations with great randomness in time and space. Satellite communications are not subject to geographical restrictions and are not subject to ground Due to network operator base station restrictions, communication quality is not affected by severe natural disasters such as earthquakes, and has become an important emergency communication method. [0003] In the face of a major disaster, in order to cope with high-frequency and random communication needs, the communication reliability of the command center (central statio...

AI Technical Summary

Problems solved by technology

[0004] At present, most of the satellite communication-based networks on the market require daily operation and maintenance inspections by the maintenance personnel of the central station, which cannot achieve real-time monitoring, cannot deal with sudden equipment failures or service system abnormalities, and cannot guarantee that the entire communication network is always working normally. state to deal with sudden centralized communication command needs
