Satellite on-orbit telemeasuring data real-time monitoring system applicable to unidirectional communication network

Abstract

The invention discloses a satellite on-orbit telemeasuring data real-time monitoring system applicable to a unidirectional communication network. The system comprises an on-orbit telemeasuring data source end network monitoring module, a unidirectional network transmission module, an on-orbit telemeasuring data application side network monitoring module. The on-orbit telemeasuring data source endnetwork monitoring module comprises a telemeasuring receiving end, a data receiving server, a file server, an on-orbit real-time monitoring terminal and a database; the unidirectional network transmission module comprises a unidirectional network gate, a data synchronization server and a file synchronization server; and the on-orbit telemeasuring data application side network monitoring module comprises a file server, a message notice server, a database, an on-orbit telemeasuring monitoring terminal and a notice terminal. The satellite on-orbit telemeasuring data real-time monitoring system applicable to the unidirectional communication network provided by the invention can achieve real-time monitoring of the satellite on-orbit telemeasuring data of the unidirectional communication network, provides data storage services for two ends of the network, and provides a data synchronization mechanism to ensure synchronism of the data at two ends.

Description

technical field [0001] The invention relates to a real-time monitoring system, in particular to a real-time monitoring system for satellite on-orbit telemetry data suitable for a one-way communication network. Background technique [0002] After the satellite is in orbit, the monitoring and control tasks of the satellite are generally carried out by the ground station system. The satellite monitoring center of the satellite developer usually can only exchange data with the ground station system through a dedicated network, and the satellite developer often needs to connect the network with the ground station system. for logical isolation. Due to the particularity of this network, it is impossible to directly send the network data to the application side network of the satellite developer, which makes it impossible for the designer to perform real-time on-orbit satellite telemetry monitoring on the office computer, reducing satellite in-orbit failures timeliness of discovery...
