Wide-area emergency interconnecting method and device convenient for communication between disaster site and command center

Abstract

The invention discloses a wide-area emergency interconnecting method and device convenient for the communication between a disaster site and a command center. A plurality of satellite emergency communication vehicles are respectively configured with a trunking terminal, a trunking base station, integrated gateway equipment and satellite communication equipment so as to form a vehicle-mounted trunking system; and the emergency command center is configured with an integrated gateway and satellite communication equipment. According to the method and the device, a voice call network switch is modified, the terminal number of the vehicle-mounted trunking system is mapped into a corresponding port, which is connected with the integrated gateway, of the voice call network switch, and the vehicle-mounted trunking system is configured with the integrated gateway of the command center; and the trunking terminal number is mapped into the address of a base station controller of the vehicle-mounted trunking system, so that the direct command of the emergency command center on multiple vehicle-mounted trunking systems and the among between trunks are realized. The method disclosed by the invention is simple, and low in construction cost, and realizes the direct and uniform command and dispatch of the emergency command center on the disaster site, and the intercommunication among satellite emergency communication vehicles.

Description

technical field [0001] The invention relates to a wide-area emergency interconnection method and device for facilitating communication between a disaster site and a command center, and is suitable for direct intercommunication between a disaster site digital cluster user and an emergency command center, and between multiple disaster site digital cluster users . It belongs to the field of communication technology. Background technique [0002] Emergency communication is a dedicated communication to deal with sudden natural disasters and public emergencies. Emergency communication usually consists of two parts, namely the communication between the emergency on-site command post and the rear emergency command center, and the emergency command between the emergency on-site command post and the disaster site. Scheduling communications. The emergency on-site command post uses a satellite communication vehicle, and the rear emergency command center communicates with the emergency...

AI Technical Summary

Problems solved by technology

This method generally cannot meet the direct intercommunication between the digital trunking users at the disaster site and the emergency command center, and between the digital trunking users at multiple disaster sites, and cannot satisfy the direct and unified command and dispatch of the emergency command center to the emergency site. It is also impossible to realize effective communication between digital trunking users at multiple disaster sites

[0004] Disaster sites are often organized by multiple people within a wide area (such as a radius of 5km) for emergency repairs and rescues. Therefore, the on-site command communication mainly relies on the wide-area mobile wireless communication network to establish a mobile or portable command communication subsystem. To realize the communication between the digital trunking users at the disaster site and the emergency command center, this method generally cannot meet the direct intercommunication between the digital trunking users at the disaster site and the rear emergency command center, and between the digital trunking users at multiple disaster sites , so that the direct and unified command and dispatch of the disaster site cannot be carried out through the rear emergency command center, and effective communication between digital trunking users at multiple disaster sites cannot be realized
