Abstract

The invention provides an efficient and automatic communication satellite video monitoring and testing system. The system comprises a lower frequency converter, a receiving demodulator, a decrypting machine, a quick-view host, a router, a testing host, a radio frequency cable, an intermediate-frequency cable and network cables. A tested system is connected with the lower frequency converter through the radio frequency cable, the lower frequency converter is connected with the receiving demodulator through the intermediate-frequency cable, and the testing host is connected with the lower frequency converter through the router and a network cable. An image transmission frame is transmitted to the decrypting machine through the network cable by the router, intermediate-state test data are transmitted to the testing host through a network cable, the encrypted image transmission frame is decrypted by the decrypting machine, and the decrypted image transmission frame is finally transmitted to the quick-view host through a network cable and the router, and control and state reading of the receiving demodulator, decrypting machine and quick-view host are completed by the testing host. The efficient and automatic communication satellite video monitoring and testing system can complete integrated testing of the tested system and has good automatic testing ability and universality.

Description

technical field [0001] The invention relates to an efficient and automatic video monitoring and testing equipment, which is especially suitable for the video monitoring system in the communication satellite field. Background technique [0002] With the continuous development of communication satellite payload technology, super-large-aperture antennas have been applied in the field of communication satellites, which requires that the deployment of large-aperture antennas must be accurate enough in the space environment, and the traditional telemetry observation method is slow due to the slow download speed of telemetry data , Poor intuition and unable to ensure the smooth deployment of large-diameter antennas. [0003] Compared with the terrestrial video surveillance system, satellite video surveillance has the characteristics of ultra-long-distance communication, so a special channel coding method is required. For example, the Chinese patent CN201120550984.2 is named rail tr...
