The invention relates to a microwave digital image transmission system for mobile command of power emergency repair work. The system comprises a video signal collecting module, an image data compression processing module, a digital modulator, a microwave emitter, a microwave receiver, a digital demodulator, an image data decompression processing module and a video signal output module, wherein the video signal collecting module, the image data compression processing module, the digital modulator and the microwave emitter are connected in turn; the microwave emitter is connected with the microwave receiver through space microwave communication; and the microwave receiver, the digital demodulator, the image data decompression processing module and the video signal output module are connected in turn. The microwave digital image transmission system for the mobile command of the power emergency repair work can realize 'single-hop' direct communication between any two of stations in a network structure and avoids additional time delay caused by doubles-hop, so the microwave digital image transmission system is suitable for broadband communication services with high real-time requirements on video, sound and the like among a plurality of points because of the small additional time delay of the satellite communication between two stations in the mesh network.
Description
technical field [0001] The invention relates to a mobile command system for emergency repair of electric power, in particular to a microwave digital image transmission system used in mobile command for emergency repair of electric power. Background technique [0002] In the process of electric power emergency repair, the image information transmission of the accident scene is very important for the commander to organize and implement the emergency repair correctly, quickly and effectively. Since on-site image transmission is affected by the space environment, the image quality of general image transmission equipment often cannot achieve good results. To this end, a specific microwave digital image transmission system is selected, using the "reflection" effect of microwaves, through space diversity reception processing and digital processing, so that it can transmit images to the mobile command center ( command vehicle), which provides intuitive information for the command p...
