The main functions of the emergency communication vehicle are as follows:
The ground command center and the emergency communication vehicle are equipped with independent dispatching systems. The dispatcher and the video server can exist as a master-slave relationship. The equipment in the field emergency communication vehicle can upload field data to the command center general server in real time as a secondary dispatch system. Or the conference venue of the video conference system; in the event of satellite link pressure or failure, the on-site emergency vehicle dispatch system is self-contained, which can completely conduct command and dispatch on the spot independently, and can hold local video through the on-site emergency communication vehicle's video server. Meetings, recording and storage of local video information can greatly reduce satellite link pressure. The two-level distributed scheduling system, which can work together, back up each other, and share pressure, is the advantage of the entire system.
Through the multi-service operation terminal video equipment and vehicle-mounted video terminal, the live image is uploaded to the emergency communication vehicle or command center in real time, and the video server of the emergency communication vehicle or command center will be output to the monitoring station for real-time display. The image is clear and the picture is smooth. The command center Leaders can make various real-time decisions based on live images.
The command center monitoring screen can monitor the scene situation through the on-board video acquisition terminal on the emergency communication vehicle, and can remotely control the monitoring direction and angle of the video terminal. Operators in the car can also monitor the camera screen synchronously to facilitate observation of the scene.
The command center communication equipment can establish a two-way voice call with the field communication equipment through the satellite link; through the gateway equipment, GSM and traditional public network telephone systems can be connected to the dispatch network; the command center dispatch platform can flexibly group all terminals and initiate at any time Voice scheduling instructions such as single call, group call, conference and broadcast.
Satellite communication can be selected from static communication or dynamic communication to meet the business needs in various situations. At the same time, it is recommended that the most suitable local satellite communication link according to different regions.
The emergency communication vehicle provides on-site wireless communication coverage through the on-board McWiLL base station equipment. Field workers can be equipped with hand-held or multi-service operation terminals, and emergency communication vehicles can be equipped with on-board dispatch terminals and on-board video equipment. These on-site terminals can communicate with each other through wireless links. On-site terminals can also be connected via McWiLL base station equipment. Realize voice and video communication with the communication equipment of the command center, and realize the upload and release of scheduling tasks. The on-site emergency communications vehicle's GS8 gateway can directly connect GSM and PSTN public network phones to the on-site support system.
