Description
technical field [0001] The invention relates to the field of satellite communication, in particular to a satellite communication device used for remote management and control of power grid infrastructure projects. Background technique [0002] At present, there are a large number of power system infrastructure projects, and the existing project management and control methods are on-site daily management of the project department, supplemented by regular and irregular on-site inspections by the superior competent department, or management of numerous project sites through wired video monitoring systems . Because the construction sites of power infrastructure projects are scattered, spanning a large area, and the terrain is complex and changeable, many project sites are located in remote locations, communication optical cables do not reach, telecom operators' network coverage is not perfect, there are many communication blind spots, and wired video surveillance cannot be reali...
