Emergency communication system

Abstract

The invention discloses an emergency communication system. The emergency communication system comprises a main base station and a sub base station; the sub base station is connected with the main basestation and further connected with a monitoring system and an emergency communication module, the emergency communication is connected with the main base station through a transfer station, and the main base station is further connected with a command and dispatch center through a wireless router; and the emergency communication module comprises a fixed terminal which is connected with an IP phone and an information acquisition module, the monitoring system comprises a wireless module, an uncompressed decoding module, a processing display module and an instruction module, and the monitoring terminal achieves information receiving and sending with the sub base station through the wireless module. The emergency communication system can quickly recover communication and is accurate in positioning.

Description

technical field [0001] The present invention relates to the technical field of emergency communication, in particular to an emergency communication system. Background technique [0002] Emergency communication usually consists of two parts, the communication between the emergency command post and the rear emergency command center and the emergency command and dispatch communication with the disaster site. The rear command center and the emergency scene usually rely on the satellite communication network, and the emergency site uses a satellite communication vehicle; there are often many people at the disaster site organizing emergency repairs and rescues within a wide area (such as a radius of 10km). Establish mobile or transportable command and communication subsystems for the mobile wireless communication network in the field. [0003] Traditional emergency command communication is mainly based on public mobile network, conventional walkie-talkie or traditional digital tr...

Problems solved by technology

The method based on the public mobile phone mobile network does not support group calls, cannot form a group team to work together, and has no priority for calls. When the called user is in a call, he can only wait, which may delay the best time for communication; the method based on conventional walkie-talkies Unable to achieve wide-area communication, limited communication distance, does not support interconnection with wired telephone or satellite communication, and cannot achieve long-distance communication; while traditional digital trunking communication systems include large equipment such as base stations and controllers, such equipment is bulky and heavy , handling and transportation are very inconvenient; traditional digital trunking uses digital trunking to communicate, and the networking is not flexible enough
