In the face of major emergencies, how to build a scientific and perfect emergency communication support system, strengthen daily maintenance and timely and effective deployment and commissioning of emergency communication equipment in case of emergencies, and ensure communication security and stability has become an urgent problem to be solved。

Challenges and needs

挑战1：

In the case of sudden disasters, first-line rescue workers often face problems such as site infrastructure damage and public network communication system breakdown.

挑战2：

Independent use of traditional communication equipment is limited。Traditional network construction requires the erection of large communication base stations, and the deployment and construction of equipment need to master the terrain in advance, which takes a long time and costs high network construction, which is difficult to meet the emergency communication needs of rapid rescue in emergencies.

挑战3：

Fire and emergency vehicle, command vehicle and ambulance tracking system does not have GPS tracking system, can not immediately locate and track, accurately convey superior orders and report the scene situation;

挑战4：

The independent communication between the command network and the detachment requires a unified rapid response dispatching system in order to form cross-departmental and cross-distance interconnection。

solution

In the face of emergencies, fire command and dispatch is the primary link in fire rescue operations。So, how to ensure reliable and smooth communication between firefighters on the front line and the command center?How to keep firefighters in close contact with each other in complex environments?How to ensure that multiple teams carry out fire operations with clear orders and do not interfere with each other......

Beifeng Communication is the industry's leading provider of emergency scene converged communication solutions，Self-developed multi-level emergency scene fusion communication solution，It can realize wide and narrow integration of emergency rescue site, mobile base station deployment and multimedia cluster command and dispatch，Build a "one map" command communication network that can be heard, seen and adjusted：

1) The backbone network + detachment network is adopted: the backbone network sets up TR8500 relay stations to achieve the same frequency and broadcast coverage in a large range, and the detachment network connects the individual soldier fusion terminal to achieve the last kilometer coverage of emergency;

2) The on-site emergency box can communicate with the command center through the satellite portable station;

3) The command center realizes positioning, recording, GIS dispatching and other functions based on the command dispatching system;

4) The command center and detachment network use TR925D portable relay station to achieve cross-level command function;

5) Fusion communication gateway to achieve fixed line, mobile phone, shortwave radio, analog radio, cluster interworking and other communication systems。

Program highlights

贴Near actual combat, multi-relay flexible support

A series of rescue site communication support tasks, such as setting up fixed stations at the rescue site to provide communication support, and setting up satellite portable stations in different forest areas and mountains to provide real-time rescue pictures for the headquarters and the rear。In the actual operation process，Portable table equipment into the field，One key power on can be fixed network，Deploy narrowband AD hoc devices flexibly based on site conditions，Realize regional signal coverage and multi-network interconnection，Form a unified voice communication network，Complete emergency communication support tasks quickly, accurately and efficiently，The full coverage of front, rear, air, ground and three-dimensional communication support system is realized。

Dynamic allocation, multi-group online communication in real time

Due to the abruptness of emergency rescue and the urgency of time, the requirements for timeliness of communication are higher。When there is an emergency to report and transmit instructions, once the channel is busy, rescuers can only wait for the end of the last call, which seriously hinders the rescue process。In addition, how can multiple units (emergency, fire, public security, medical, etc.) ensure that each group performs its duties and that real-time unified command of on-site commanders is crucial!

The BF-TR8500 digital repeater can be used as a channel machine for SVT systems to manage base stations consisting of multiple channel sets through a dedicated channel controller。In the SVT system, the channel resources provided by all the channel machines will be uniformly managed and allocated。As long as the channel load is not fully occupied, the end user can make a call without manual switching。Field commanders can organize multiple intercom terminals into multiple groups as needed, and commanders can choose one group, several groups or all members to select calls, effectively meeting the emergency fire scene traffic density and a wide range of work groups。

Wartime operation and maintenance, professional alarm protection

In the emergency rescue site, the command and dispatch management platform at the rear of the corps is set up in the assembly area, and a relay portable station is set up in the backbone area to realize the rapid opening of the command and dispatch network and ensure the real-time smooth flow of video conferencing, wireless communication and actual combat command system。On-site maintenance of emergency communication equipment and maintenance of faulty equipment can ensure the integrity of emergency communication equipment。

The BF-TR8500 digital repeater features a professional-grade 19-inch 2U standard rack-mounted construction with an all-metal, rugged housing。Users can configure a proper duplexer based on the frequency of use and install it in the chassis. This eliminates the need for additional space, saving deployment area, and diversifying installation and deployment methods。When the device is dealing with various problems that may occur during operation, it prompts maintenance personnel to perform troubleshooting。The device built-in CF active cooling design can ensure that the product can work more robustly under high load conditions or lack of good room temperature environment。
