Background technology
Emergency communication equipment can have been accomplished the communication function (comprising voice, data and video) between emergent scene and command centre at present, but the delivering path that signal post needs all will rely on the dedicated communications network of existing every profession and trade, public mobile network, wideband satellite communication network or maritime satellite communications network.General emergency communication equipment does not provide satellite positioning functions, and the location external navigator of many dependences provides, and locating information is uploaded special use, the public communication network that needs to rely on other.
Present emergency communication equipment remains the defective aspect access way and locating information transmission.
1) from the emergency communication access way
The shortcoming of dedicated communications network: there is bigger limitation usually in dedicated communications network; General some conventional key areas that only cover enterprises and institutions, most of zones then do not cover, in case emergent accident takes place; Also need utilize wired, optical cable, wireless mode to extend to the place where the accident occurred point to transmission network from original communication network; Can increase time, the workload of emergency management and rescue so undoubtedly, and bring very big uncertainty, general on-the-spot optical fiber cable for field operation, the twisted-pair feeder of laying 1km; Consuming time all about 0.5h; If wireless microwave equipment need be built in the scene, the environmental condition of then dependence accident generation area, the complicated zone of a lot of geographical conditions can't utilize wireless microwave to transmit.
Rely on the shortcoming of common network: accident is when particularly natural calamity takes place; The destructive power of flood, landslide, mud-rock flow is often very big, and this moment, the mobile network of each operator was also destroyed probably simultaneously, for example in Guangdong in 2006, Hunan floods process; Beijing-Guangzhou Railway is burst by large tracts of land; And move, the base station signal of UNICOM also interrupts one after another, itself also need repairing, so emergency communication obviously can not rely on public network fully.
The shortcoming of broadband satellite network: mainly be that access device is more numerous and diverse, comprise satellite modem, satellite power amplifier, satellite antenna and power-supply device etc., weight of equipment generally is not less than 40kg, and the underdeveloped disaster of traffic environment zone is difficult to reply.The expense that a shortcoming in addition is exactly a wideband satellite communication is higher, and the expense of general 1Mbps bandwidth is 2000 yuan/h.
The shortcoming of marine satellite network: expensive, per minute cost of the phone call are 1 dollar, and data communication is 7 dollars/MB.
Emergency communication system based on above diverse network perhaps relies on the dedicated network that does not cover the position; The perhaps dependence common network that possibly in disaster, might occur interrupting itself; Perhaps rely on light and handy but expensive marine satellite network, perhaps rely on the broadband satellite system that expense is higher and access device is overweight.In a word; Existing emergency communication equipment remain or the network coverage not in place, perhaps network is fragile, perhaps expensive; The perhaps additional overweight defective of access device; Above defective might cause emergency communication equipment unavailable, perhaps uses inconvenience, and perhaps expensive is unfavorable for regular emergency drilling work.
2) see from satellite positioning functions
Most emergency communication equipment do not possess satellite positioning functions; The employing GPS location that also has; Adopt the shortcoming of GPS location: at first gps system only possesses the simple function of positioning oneself, and its locating information is uploaded needs to rely on other networks, its position otherwise the center commanding has no way of finding out about it.Second gps system lacks basic two-way communications capabilities, promptly has only unidirectional receiving function.The 3rd, gps system depends on the U.S..
