Description

Technical Field

[0001] The invention relates to a cross-domain ground measurement, transmission and control network real-time monitoring system and method, belonging to the field of digital transmission and communication of electrical measurement and control systems. Background Art

[0002] The launch vehicle ground test and launch control system realizes the test and launch of the launch vehicle on the ground. The terminal ground test and launch control network system provides the transmission link of instructions and status for the front-end launch vehicle and the back-end test and launch hall, so that the back-end test and launch instructions can control the front-end test equipment action, and the status of the front-end equipment can be fed back to the back-end test hall. At present, the working status monitoring of the traditional terminal ground test and launch control network system mainly realizes the network communication delay between the front-end and back-end equipment, the backbone network link on-off monitoring and the capture of key data flows.

[0003] With the implementation of the requirements for localization and independent control of ground equipment, the ground test, launch and control systems of various types of launch vehicles are undergoing universalization, productization and serialization research and development. At the same time, the remote test network of the remote control hall and the final assembly plant, XX launch site and XX launch site has been opened. The subsequent target range test network, final assembly plant test network and back-end remote control network will be "woven" into a large network, and this cross-domain and remote network monitoring work is becoming increasingly important. The traditional terminal ground test, launch and control network system uses commercially available software such as solarwind, sniffer, and wireshark to monitor the network system, but at present, such software cannot meet the monitoring needs of the ground test and control network after the upgrade, and cannot adapt to the cross-domain network monitoring work scenario, nor can it meet the existing localization and independent control requirements.
