Abstract

The invention discloses an emergency communication system based on an intelligent terminal. The emergency communication system based on the intelligent terminal comprises the intelligent terminal which supports wireless transmission technology such as Bluetooth, wireless fidelity (WIFI), Zigbee or amateur radio, and software which runs on the terminals and supports an offline end-to-end communication mode, so that certain communication capacity can be kept under the condition that cellular mobile communication network infrastructure is seriously damaged, and rescue and relief work is convenient. By the adoption of the scheme, when traditional communication network does not work due to various natural disasters such as an earthquake, an end-to-end communication direct connection mode can be adopted, and a certain distance communication can be conducted when the network infrastructure is removed, so that a trapped person who is buried under ruins knows a position and a state by making a call and rescue and relief work is quite beneficial. Therefore, the emergency communication system based on the intelligent terminal has high economic value and social benefits.

Description

Emergency communication system based on intelligent terminal

Technical field

The present invention relates to wireless communication technology field, be specifically related to based on intelligent terminal, with the emergency communication system of end-to-end direct-passing mode establishment.

Background technology

Traditional cellular mobile terminal need to have the basic network facility to support, and could communicate each other, if when going out phenomenon and cause basic network to work because of various natural calamities such as earthquakes, just do not possess any communication capacity between terminal.And natural calamity happens occasionally at present, in case the basic network damage is serious, due to the support that has lost the communications infrastructure, the rescue and relief work progress is very difficult.

On the other hand, present intelligent terminal, the overwhelming majority has bluetooth and WiFi communication module, supports file transfer functions definitely.The communication software that carries of terminal just, the bottom linkage function is complicated, needs repeatedly to confirm repeatedly operation, uses very complicatedly, so few people use.Do not possess the function of carrying out voice, short message transmission yet.

Bluetooth, WiFi wireless communication module belong to the standard configuration of intelligent terminal substantially, but the defective that exists is that communication distance is very short, thereby the scope of application is limited.Comparatively speaking, at the application in the fields such as industry automatic control comparative maturity, cost is also lower, and communication distance is also long more a lot of than bluetooth at present for ZigBee technology.General Bluetooth communication distance is in 8～30 meters scopes, and Zigbee is in 100 meters scopes.With respect to bluetooth, WiFi and Zigbee, the communication distance of ham radio is just longer, thereby advantage is more obvious, be that present intelligent terminal is not also supported the transmitting-receiving of ham radio substantially, although some mobile phone terminal possesses FM receiver function, can only receive, can not launch.

Summary of the invention

The present invention proposes a kind of emergency communication system based on intelligent terminal, comprise: the intelligent terminal of supporting the Radio Transmission Technologys such as bluetooth, WiFi, ZigBee or ham radio, and the software of the end-to-end communication pattern of the support off-grid that moves on these terminals, so that in the situation that the serious damage of network infrastructure, can keep certain communication capacity, facilitate rescue and relief work.Adopt the present invention program, when going out phenomenon and cause conventional communication networks to work because of various natural calamities such as earthquakes, can adopt the direct mode operation of end-to-end communication, break away from network infrastructure and carry out the communication of certain distance, from the trapped personnel that is buried under ruins, make a phone call and just know it where is, what state, this will be highly beneficial to rescue and relief work.Therefore, the present invention has very high economic worth and social benefit.

Can be used for the communication technology end to end, mainly comprise the Proximity Wireless Transfer Technologies such as ham radio, bluetooth, WiFi, ZigBee.These technology have pluses and minuses separately, particularly for mobile phone terminal, some characteristic limitations of mobile phone the use of correlation technique.The ham radio technological merit is that communication distance is far away, and the penetration capacity of signal is strong, but the transmitting power that needs is very large, and mobile phone is not generally supported at present, need to compare large terminal transformation and upgrade; The Bluetooth technology advantage is to be operated in unauthorized frequency range, and nearly all mobile phone is all supported function of Bluetooth communication now, the communication security performance is high, shortcoming is that communication distance shorter (in 8～30 meters scopes) and power consumption are large, need to carry out repeatedly application and confirmation during connection, the connection of process more complicated and foundation is unstable; The WiFi technology is to develop in recent years very fast wireless communication technology.Smart mobile phone major part on market can both be supported WiFi communication.Its advantage is that communication distance is grown (in 76～122 meters scopes), stable connection, and message transmission rate is high, and shortcoming is that power consumption is very large, and fail safe can not be guaranteed reliably.ZigBee technology is a kind of close range communication techniques more widely of using in productive life.Its advantage is communication distance long (100 meters left and right), and power consumption is very low, does not generally support but shortcoming is also present mobile phone, need to compare large terminal transformation and upgrade.

Simultaneously, the system that generally uses according to mobile phone terminal, with Android, IOS and WindowsPhone platform as Software Development Platform.Based on Bluetooth technology, by api function, the function package of bottom, simplify connection procedure, to user transparent, convenience and the reliability used to increase the user.Based on the WiFi technology, to expand communication distance, by supporting the protocol infrastructure of end-to-end communication.Based on ZigBee technology, by external hardware module, be connected with intelligent mobile phone terminal with the Mini USB interface, further to expand communication distance, increase the availability of this technology.In addition, based on the ham radio technology, by external hardware module, the MiniUSB interface is connected with intelligent mobile phone terminal, to continue to expand communication distance.

In addition, usage data storehouse technology realizes the binding of device identification ID and user's mobile communication mobile phone number, can use phone number to search when searching the user, make the user in use convenient, more meet everybody use habit, experience to promote the user.

Generally speaking, by the present invention, make the intelligent mobile phone terminal that originally can only carry out voice, note business transferring under cellular network, can be in the situation that is badly damaged because of various factors generation basic network, by between mobile phone terminal not by means of the direct communication of basic network, build emergency communication system, very big convenient rescue and relief work.
