Embodiment 1

[0033] figure 1 It is a flow chart of the method for automatic switching of satellite ground station links described in this embodiment.

[0034] refer to figure 1 As shown, the satellite ground station link automatic switching method described in this embodiment includes the following steps:

[0035] S1. Automatically detect the link of the ground station to determine whether there is any abnormality;

[0036] Exemplarily, the satellite ground station link described in the embodiment of the present invention implements the interconnection between the node devices on the link based on a switch matrix, such as figure 2 shown. In this way, to change the connection relationship of different devices between different link nodes, it can be easily realized only by changing the switch matrix, which can improve the system efficiency for ground station tasks with a large number of devices. through as image 3 The multiple different switch matrices shown are cascaded to connect mu...

Embodiment 2

[0069] On the other hand, the present invention also provides a satellite ground station link automatic switching system, such as Figure 8 As shown, the automatic switching system 800 includes:

[0070] The link detection module 801 automatically detects the ground station link to determine whether there is an abnormality;

[0071] The fault location module 802, if there is an abnormality, automatically performs fault location on the ground station link, and determines the fault node;

[0072] The link switching module 803 automatically selects a backup node to replace the abnormal node, and rebuilds the link.

[0073] Wherein, the ground station link is built based on a cascaded switch matrix; correspondingly, the re-establishing the link includes: re-establishing the link by switching the connection mode of the cascaded switch matrix.

[0074] Further, the automatic switching system 800 further includes: a link initialization module 804, which automatically extracts a lin...

Embodiment 3

[0077] On the other hand, the present invention also provides a satellite ground station monitoring and management device 900, such as Figure 9 As shown, the monitoring and management device includes:

[0078] The equipment monitoring module 901 collects the information of the equipment contained in the ground station, detects abnormalities, and controls the parameters of the equipment;

[0079] The link management module 902 manages link-related device resources, uses the device resources to build a link, and performs automated testing on the link;

[0080] The fault diagnosis module 903 analyzes the abnormal link and locates the faulty node in the link.

[0081] Based on the monitoring and management device 900, a corresponding satellite ground station link automatic switching method can be implemented, including:

[0082] S10, the link management module automatically detects the link of the ground station, and judges whether there is an abnormality;

[0083] S20. If the...

Abstract

The invention discloses a satellite earth station link switching method, which comprises the following steps: detecting whether an earth station link is abnormal; if so, carrying out automatic fault location on the earth station link to determine a fault node; and selecting a standby node to replace the abnormal node, and re-establishing a link. The system can finish all work of link test, fault diagnosis and fault recovery in a full-automatic manner without manual intervention, can ensure 7*24 hour all-weather operating of an earth station under an unattended condition, greatly improves fault-tolerant capability and adaptive capacity of the earth station system and expands application environment of the earth station system.

Description

technical field [0001] The invention relates to the technical field of satellite ground station applications, in particular to a satellite ground station link switching method and system. Background technique [0002] With the continuous development of information systems, the degree of automation in the field of ground station applications is also deepening. The requirements for industrial automation control systems are not limited to the basic function of automatically dispatching professional equipment to complete routine tasks according to established procedures. How to improve the overall efficiency of the system and how to improve the successful completion rate of tasks is a more concerned issue at present. [0003] According to the existing domestic ground station operation experience, when the receiving task execution fails, more than 70% of the reasons are due to the abnormality of the channel link. In order to solve this problem, domestic ground systems have adop...
