Description
Technical field
The present invention relates to a kind of emergency communication method and communicator, particularly relate to the emergency communication system and method for netting based on mobile cellular telephone net and Ad-hoc.
Background technology
China is the multiple country of natural calamity, and earthquake, flood, the natural calamities such as typhoon of passing by happen occasionally.Especially in recent years, the major disaster sexual behavior parts such as ice and snow is sudden and violent, special violent earthquake, extraodinary flood, mud-rock flow, mine disaster frequently occur, and cause massive losses to the life of the mankind and property.Current China tackles similar accident, and emergency communication technology mainly contains following several:
The emergency communication of landline telephone mode
The advantages such as landline telephone has wide coverage, and audience is large.Generally, fixed telephone network is all the preferred network of emergency communication, and reason is that its expense is lower, capacity is larger.The urgent calls such as usually said in us 110,119,122 are exactly a kind of traditional emergency communication means in fact.But its shortcoming is that landline telephone is subject to the restriction of cable, once in case of emergency cable is damaged, then communication will stop, and repairing efficiency is long.
Mobile cellular telephone
GSM and CDMA technology are the topmost access waies of current Emergency communication vehicle, and its advantage is that transmission speed is fast, and infrastructure is complete, and use cost is low, and transfer of data is reliable, and the error rate is low.Shortcoming is that bandwidth is less, and for special applications, as passed the image of high definition, or need the data transmission capacity of large bandwidth, GSM and CDMA technology just seem awkward.
Satellite emergency communication
Satellite communication have communication distance far away, cover region and extensively, by geographical conditions restriction, investment to have nothing to do with communication distance and the feature such as networking flexibility, being highly susceptible to realizing telecommunication, is a kind of important means of modern communications, obtains extensive use in the whole world.Have motor-driven, flexible, that implementation is good feature, when major natural disasters occur, when ground line is damaged, satellite communication often can play unique effect simultaneously.But the industry of satellite communication simultaneously exists some shortcomings, and higher to the requirement of technology and equipment, satellite equipment system cost is higher, and it is more high that satellite rents link cost, these problems have a strong impact on the universal of it.
Emergency set communicates
Radiothermy (, at 10-100m, frequency is at the electromagnetic wave of 3-30MHz for wavelength) carries out radio communication and is called short wave communication.The development of short frequency adaptive technique and application, drastically increase reliability and the validity of short wave communication.Self adaptation emergency set equipment volume is little, and easy transportation and installation are simple to operate, and be relatively applicable to mobile communication and use, shortcoming is that frequency resource is limited, and comparatively large by landform, landforms, weather effect, communication quality is difficult to be protected simultaneously.
We also do not set up a set of perfect emergency communication system at present, rescue technique development is slower, rescue communication equipment is also relatively backward, such as on May 12nd, 2008 Sichuan special violent earthquake rescue action, satellite communication network is in state of paralysis completely in early stage, and the early warning from satellite private network that all departments set up is one and is similar to closed system, because of independent separately, do not connect mutually, make domestic ten hundreds of satellite car become ornaments.Because satellite system and fixed network, mobile network disconnect substantially, even if the communication network in disaster area can be repaired fast, still there is whole process or large area and cover the problem being difficult to realize, seriously hinder the progress of the disaster relief.
How to successfully manage the accident that this kind of destructive power is strong, breakdown speed is fast fast, become the problem that pendulum is extremely urgent in face of us.Therefore, develop a kind of Emer-gency Communication that the functions such as real-time video transmission, voice call, GPS location can be provided in the presence of a harsh environment, set up the broadband emergency system that both pictures and texts are excellent, communication cooperates mutually, multiple business is merged, and " at ordinary times " and " wartime " two states can be provided, improving the very first time is that emergency command obtains in-situ data efficiency, promotion rescue work is carried out smoothly, completes whole rescue action tool and be of great significance.
