Beifeng Emergency Communication "small system" is a portable digital private network communication solution configured for emergency rescue scenarios in extreme environments. The system is composed of portable repeater stations and handheld terminals, with the primary goal of quickly forming a field communication command and dispatch system。
Fast mobility, flexible deployment
To solve the problem of narrowband signal coverage under complex conditions at the front line, the Beifeng emergency communication "small system" can set up a communication command organization structure such as "first-line combat detachment - front command network" in advance，Rescue members can directly "just go" in case of emergency，Quickly assign communication devices to related members，Immediately set up the on-site private network communication network。
The direct distance of a single walkie-talkie is usually within the range of 3-5 kilometers, and when the distance between the flood control points is far, the communication distance can be expanded through the backpack trunk, through the personnel to move the position flexibly in real time。Through the emergency communication "small system" (BF-TR925(D) relay station +BF-TD910 handheld terminal) to form a 5-10km knap-back relay network communication, to achieve real-time communication between the flood control command and management center and the upstream and downstream rescue and inspection personnel of the dam。
Beifeng Emergency communication "small system" is based on the mainstream DMR time division multiple access technology, and a portable repeater can support two rescue teams to talk at the same time, which doubles the coverage communication efficiency of the team network。
Beifeng portable repeater can also be transformed:
1. Become a Backpack ManIf the road is rough in remote areas (mountain/muddy paths, etc.), the portable relay can be equipped with batteries and backpacks, carried by the team members。
2. Become Car ManIf the mission area is in the front line with clear roads, the portable relay host can be loaded on the car dock, and the vehicle becomes a communication command vehicle。The modular design makes the portable relay adaptable to multiple mission scenarios。
Double section and double defense, both inside and outside the group: realize the systematic coordination of multi-unit operations
Front-line rescue and disaster relief teams are often divided into multiple teams to perform corresponding tasks at the same time according to different task requirements。How to ensure that the internal communication of multiple flood control teams in the process of disaster relief is smooth, and how to receive the instructions of the former commander in time?BF-TD910 handheld terminal in Beifeng Emergency Communication "Small system"，Its double segment double waiting function，Allows each team to have their own communication frequency at the same time，It can also wait for the communication frequency of the former commander at the same time，Make the "small system" realize the independent communication of each unit in the emergency team，And can communicate with the commander in real time，Ensure that instructions are uploaded and issued。
Digital-to-analog compatibility, one key to each other
In the process of flood relief, in addition to the local rescue and relief teams, there will be multi-department or cross-district support teams such as the military, armed police, health, and transportation to work together to contribute。At this time, how to quickly establish a common command and communication network across departments is the basic guarantee for the efficiency of flood relief organizations。
Beifeng emergency communication "small system", through the portable cross-segment repeater BF-TR925D, can realize different network networking of different functional departments, compatible with digital and analog intercom communication networks, on the basis of not adjusting the original communication frequency of each department, to achieve cross-department unified communication scheduling。At the same time, functional departments at all levels can realize one-click mutual transfer, so that the commander can directly communicate with front-line personnel, and improve the efficiency of instruction uploading and issuing。
