Faced with the rescue situation of tall buildings and complex surrounding and internal environments, the rescue team has put forward higher requirements for the mobility of the communication system. BelFone Ad-hoc network equipment is easy to carry. When the building power is cut off and there is a blind spot in the public network signal coverage, firefighters can quickly and flexibly use BelFone Ad-hoc network to establish a voice transmission link from the inside of the building to the on-site command center. At the same time, with the help of BelFone Ad-hoc, the image signal is extended to the blind spots of high-rise and underground image transmission, which helps to ensure that the broadband and narrowband self-organizing network link can more smoothly transmit the situation inside the building back to the on-site command center and the rear command center in a timely manner.
The fire communication vehicle quickly sets up a temporary on-site command center. Outside the fire scene, the on-site commander can view the information sent back by the front-line in real time through the front emergency dispatch command platform, and can use the multi-mode fusion terminal, mobile command terminal, portable command center and other equipment carried by the firefighters for on-site command and dispatch, which effectively guarantees the efficient development of the front and rear dispatch and rescue work.
Emergency rescue in underground space
In terms of emergency rescue in underground space in cities, subways are fast rail transit built in cities. Their trains run on fully enclosed lines. The lines are basically located in underground tunnels and are often in communication blind spots. Once an accident or emergency occurs, it will greatly hinder emergency rescue work.
Emergency support personnel use narrowband self-organizing network mobile stations to carry on-site voice private network signal coverage, realize indoor confined spaces and external transmission links, and transmit real-time data information such as on-site voice and on-site situation monitoring, and carry multi-mode fusion terminals as communication terminals. Commanders use the on-site temporary command center built by the rear communication support group to control the on-site situation to the greatest extent possible. At the same time, the on-site commander transmits the on-site rescue information to the rear command center in real time through satellite links, and improves the rescue coordination capability and emergency operation efficiency through real-time information sharing.
Rescue in complex urban scenes
In rescue in complex urban scenes, it mainly involves concentrated local disaster scenes in the city, such as collapse, fire, explosion, harmful gas leakage and other emergency scenes in large buildings (including basements), underground spaces (tunnels, subways, etc.), hazardous chemical industrial parks, etc.
BelFone provides a public-private integrated emergency communication guarantee solution for disaster rescue in complex urban scenes: using the 370MHz wireless emergency communication system as the bottom-line communication, combined with the public network cluster for communication guarantee backup. First, the 370MHz wireless emergency communication system is based on daily cluster fixed stations (can be combined with cluster mobile stations when necessary) as the core backbone network for urban disaster rescue; secondly, through the characteristics of self-organizing network mobile stations that are lightweight and portable, and can be quickly deployed on site and used immediately, according to the needs of the rescue mission, it can be extended and blinded to indoor, underground, tunnel and other areas in real time, and an independent emergency communication network can be quickly established to ensure smooth emergency communication. In addition, the public network is used as a wireless interconnection method to realize the interconnection between the public network terminal and the cluster fixed station and the rear command center, and realize cross-regional collaborative combat capabilities.
