Abstract
The utility model relates to a 3G offline base station-based audio/video communication system for fire-fighting and rescue scenes of fire fighting forces, which solves the problem that combatants cannot be in audio/video communication with commanders in real time because of communication blind areas in the fire-fighting and rescue scenes at present. The system comprises a 3G offline base station management gateway, a plurality of 3G offline base station terminals, and a plurality of mobile terminals special for the fire-fighting and rescue scenes, wherein the 3G offline base station management gateway is used for managing the plurality of 3G offline base station terminals; the plurality of 3G offline base station terminals are used for supporting three communication standards such as CDMA2000 (synchronization code division multiple access), WCDMA (wideband synchronization code division multiple access) and TD-SCDMA (time division-synchronization code division multiple access) and accessing the mobile terminals in the respective signal coverage range; and the plurality of mobile terminals special for the fire-fighting and rescue scenes establish wireless communication links with 3G offline base stations by means of scene 3G networks and realizes the audio/video communication between the mobile terminals and other combatants as well as the commanders in the system. According to the 3G offline base station-based audio/video communication system, the communication support capability of the fire fighting forces in the fire-fighting and rescue process is greatly improved, and the fire fighting and rescue efficiency of the fire fighting forces is effectively improved.
Description
Technical field
The utility model relates to the wireless audio and video communication system, relates in particular to a kind of on-the-spot audio frequency and video communication system of fire brigade fire fighting and rescue that is exclusively used in.
Background technology
Along with the develop rapidly of Chinese national economy, city middle-high building, hypogee, petroleum chemical enterprise grow with each passing day in recent years, and causing the calamity factor sharply increases, and fire or other disastrous accidents frequently take place.Because the uncertainty at fire fighting and rescue scene, the complexity of building are ensured for therefrom the on-scene communication of fire brigade fire fighting and rescue and have brought huge pressure.China's fire brigade is to utilize 350Mhz public security cluster net to carry out voice communication at the on-the-spot communication mode that is adopted of fire fighting and rescue at present; Communication mode is comparatively single; In some special disasters place (in the complicated building structure) taking place and meet with communication blind district through regular meeting, causes communication disruption.And also demonstrating the situation that rises year by year because on-scene communication ensures the ineffective economic loss that causes and fireman's injures and deaths.
The fire brigade of countries in the world adopts the cluster network of different frequency more at the communication mode of fire fighting and rescue field by using at present; Adopt the hand-hold type radio station to carry out voice communication between on-the-spot fighter and the commander; Because the attenuation characteristic of electromagnetic wave in the transmission course of space all suffered from a difficult problem that causes communication failure owing to the existence of communication blind district.
Summary of the invention
In order to solve the problem of above-mentioned existence; The utility model provides a kind of fire brigade fire fighting and rescue based on 3G off-grid base station on-the-spot audio frequency and video communication system; Realized that the on-the-spot region-wide non-blind area of wireless signal of fire fighting and rescue covers, and has ensured the real-time audio and video communication link between belligerent fighter and the commander.
The purpose of the utility model realizes through following technical proposals: the on-the-spot audio frequency and video communication system of a kind of fire brigade fire fighting and rescue based on 3G off-grid base station; It is characterized in that; This system comprises: a 3G off-grid BTS management gateway; Be used to manage a plurality of 3G off-grid base station terminals, bottom communication is realized the data exchange service between a plurality of 3G off-grid base station terminals based on the tcp/ip communication agreement.
A plurality of 3G off-grid base station terminals are supported CDMA2000, WCDMA and three kinds of communication standards of TD-SCDMA, realize its interior portable terminal access of signal cover separately; Set up with 3G off-grid BTS management gateway that data communication is connected and exchanges data.
A plurality of fire-fighting fire extinguishing rescue site special mobile terminal utilizes on-the-spot 3G network and 3G off-grid base station to set up wireless communication link; Realize communicating by letter with the audio frequency and video of internal system.
The beneficial effect of the utility model: through to 3G off-grid station technology and real-time audio and video Research of Communication Technology; Researched and developed the utility model---based on the on-the-spot audio frequency and video communication system of the fire fighting and rescue of 3G off-grid base station, this system is made up of 3G off-grid base-station gateway, 3G off-grid base station terminal, three parts in fire-fighting fire extinguishing rescue site special mobile terminal.Existing CDMA2000, WCDMA and the three kinds of communication standards of TD-SCDMA of China are supported in 3G off-grid base station in the system, have realized the non-blind area all standing of the on-the-spot 3G signal of communication of fire fighting and rescue.Solved the on-the-spot because problem of communication blind district of fire brigade fire fighting and rescue cause between on-the-spot fighter and the commander can't real time communication technical barrier, ensured the audio frequency and video communication link between the fighter and commander in the fire fighting and rescue scene effectively.Native system belongs to proprietary network at the on-the-spot 3G cordless communication network of setting up of fire fighting and rescue, separates with the 3G public mobile communications network, guarantees that it does not disturb.Fire fighting and rescue floor manager person and fighter can utilize fire-fighting fire extinguishing rescue site special mobile terminal to realize that real-time audio and video communicates by letter, and realize " on make descending " and " conditions at the lower levels report ", have greatly improved the fire fighting and rescue fighting efficiency of fire brigade.
