Solution of portable emergency communication system for flood control and rescue

　　6 Since the month , Many cities in southern China have been hit by rainstorms , Urban waterlogging 、 Road collapse 、 People trapped , The safety of people's lives and property is seriously threatened . In the face of the fierce “ flood ”, Local fire rescue team Wu Wen “ Flood season ” And move , Seize every minute and second , Spare no effort to rescue and evacuate the trapped people .

　　

 

　　 Beifeng communication aims at the existing difficulties in flood control and rescue , To create “ Different frequency relay station (BF-TR925)+ Cross section relay station (BF-TR925D)+ Digital terminals (BF-TD910)” Portable solution for networking architecture ：

　　① Temporary inter departmental communication

　　 Emergency rescue 、 Public Security 、 fire 、 signal communication 、 Electric power 、 medical and health work 、 Nearly 1000 emergency rescue teams such as transportation launched flood control and rescue , Due to different frequency points , How to ensure that the superior and subordinate within the Department 、 Cross departmental communication , At the same time, ensure no interference with each other , Become the primary consideration of emergency communication during flood control .

　　

 

　　 Regarding this , Beifeng communication adopts BF-TR925D The way to realize wireless link bridging , When one BF-TR925D When the communication distance cannot be met , The communication distance can be extended by adding cross section relay stations . In actual flood control operations , Realize the rescue team A With the rescue team B In none IP Cross band interworking under the condition of network .

　　② Fast team building without interference

　　 When the danger escalates or the dam releases flood , How fast the command center or unit leader 、 accuracy 、 Without interference, it is necessary to convey instructions to the front-line rescue personnel in the flood discharge area ? Beifeng communication through BF-TD910 The digital terminal locks a single channel , Conduct on-site team formation , It is convenient for the superior to set up a flood control and rescue team in real time according to the on-site situation .

　　③ Long distance signal support

　　 Flood situation caused by rainstorm , Most of them are accompanied by the destruction of power and communication equipment in local areas , Traffic jam, etc . The rescue team can only send a small number of rescue workers to the front line , Most need to provide data information transmission and support at the rear , There is a difficulty in long-distance communication without network . Beifeng communication aims at this situation , Set up base stations or piggyback relays between flood control points , The front-line personnel can flexibly transfer positions in real time , Expand communication distance . At the same time through BF-TR925(D) Relay station +BF-TD910 Composition of handheld terminal 5-10 Kilometers of backpack relay network communication , Realize the connection between the reservoir management station and the upstream of the dam 、 Real time communication between downstream rescue and patrol personnel .

　　

　　 Besides , The flood control emergency communication vehicle can carry BF-TR925(D) As a supplementary coverage of fixed base stations , It can also be networked independently , Used as a bridge interconnection of spans . Equipped with BF-TD910 The handheld terminal can make up for the distance pain point of the terminal product at the flood control site , Realize long-distance communication coverage , Meet the requirements of individual combat communication operation of field personnel , To ensure that in case of emergency 、 accuracy 、 Set up the equipment safely 、 Withdraw 、 Transfer work .
