The traditional emergency command and communication system mainly uses satellite communication vehicles as the working unit, and communicates with the command center through on-board telephones, X-DO2401 985210203 voice dispatch terminals. On site personnel can only communicate with the satellite communication vehicle and the command center through narrowband voice equipment such as walkie talkies, and cannot provide all on-site information feedback to the command center, hindering the commander from making accurate decisions. Putian’s emergency communication live streaming solution has taken into account this “flaw”. Putian’s satellite communication vehicle has added HDMA broadband base stations, achieving direct communication between the site and the command center.

The Putian emergency communication live broadcast solution consists of satellite communication system, video and audio processing system, X-DO2401 985210203 on-site wireless communication system, and other components. The satellite communication system of the satellite communication vehicle mainly consists of antenna system (static or dynamic antenna system), power amplifier system, modem system, and other parts. The size of the antenna reflector and the power of the power amplifier need to be calculated through the link based on the actual geographical range of the satellite communication vehicle, the geographical location of the satellite and satellite ground station used, the size of the antenna reflector, and the amount of business data required for transmission. Other system equipment can be flexibly configured according to the actual usage needs of customers. At present, it has been widely used for rapid and timely information collection and emergency response communication in various public security, oil fields, fire protection institutions, logistics support, medical institutions, etc.
