When there is a major disaster (such as earthquake, tsunami, flood, fire, mudslide, major traffic accident, etc.)，This is often accompanied by the destruction and breakdown of infrastructure such as communications，The usual means of communication are basically ineffective，The affected area is basically an information island，The rapid establishment of a powerful 370MHz emergency command and dispatch narrowband wireless communication network is a necessary condition for effective rescue and disaster relief operations,This is where emergency communication equipment comes in......

In the face of devastating natural disasters such as earthquake disasters, infrastructure including communication facilities, transportation facilities, power facilities, etc. are completely destroyed, and the disaster area is isolated to a certain extent, and all on-site information needs to be collected, sent and feedback in real time。Emergency command and communication support plays a key role in the smooth implementation of earthquake disaster relief work, and is a necessary means to ensure the efficient development of disaster relief and emergency command work。...

After the Department of Emergency Management was established，And issued the Strategic Planning Framework for the Development of Emergency Management Informatization (2018-2022).，It puts forward clear requirements and guidelines for the information construction of emergency management departments at all levels in the country，It is required to strengthen the construction of disaster monitoring and early warning platform network，Build a natural disaster monitoring system that integrates space, space and earth，Strengthen connectivity and data sharing，We will improve comprehensive monitoring of multiple disaster types and disaster chains, early identification of risks, and early warning......

In the face of sudden forest fires, how to scientifically formulate emergency rescue plans according to the disaster scene environment, quickly build emergency rescue communication links, and dispatch all rescue forces for joint rescue operations in the first time has become the key to rescue and rescue missions。

BF-9000 mission-critical emergency communication system，The overall design idea is to use BF-TR900 fixed digital repeater to cover the wide area，To ensure daily patrol personnel communication use，The BF-TR925 portable dual-band digital repeater can be used as a supplement to the fixed repeater，It can also be temporarily deployed in emergency situations when the fixed base station is down，Ensure intercom communication in the target area。...

In view of the current difficulties in flood prevention and rescue, Beifeng Communication has created a portable solution with "different frequency relay station (BF-TR925)+ cross-segment relay station (BF-TR925D)+ digital terminal (BF-TD910)" as the networking architecture
