Dual-network redundant Ethernet communication system for rocket ground control of carrier rocket

The invention provides a dual-network redundant Ethernet communication system for rocket-ground control of a carrier rocket. The system comprises an on-rocket switch arranged on the rocket, a front-end switch and a rear-end switch, wherein the front-end switch and the rear-end switch are arranged on the ground; dual-network redundant communication links are formed between the on-rocket switch and each on-rocket single machine as well as between the on-rocket switch and the front-end switch; a dual-network redundant communication link is formed between the front-end switch and the rear-end switch; the front-end switch is in communication connection with the front-end test emission control equipment; and the back-end switch is in communication connection with the back-end server, the measurement and control host and the data browsing terminal. According to the application, the capabilities of digital control between the rocket and the ground and on-line monitoring of mass system test data are realized, the rock
