Description

A kind of emergency communication method and terminal
Technical field
The application relates to communication technical field, particularly relates to a kind of emergency communication method and terminal.
Background technology
China is vast in territory, and geographical geology, weather conditions complexity are one of countries that natural calamity is the most serious in the world, and natural calamity has following characteristics:
(1) kind is many, has almost included in the world various types of natural calamities.In all kinds of disasters, especially maximum with the harm of flood, arid and earthquake.
(2) frequency of disaster generation is high, intensity is large, loss is serious.China have saying of " three years old famine, declined in six years old, 12 years old famine ".According to the historical data statistics, in B.C. 206~1949 years 2155, floods occur altogether 1029 times, larger drought 1056 times, almost bloods and droughts has it every year, and the above disaster of maimed ten thousand people occurred once in 10~20 years.Over nearly more than 40 years, drought appears every year on average 75 times, flood 5.8 times, and typhoon 6.9 times, freezing disaster 2.5 times is all considerably beyond the average frequency in the world.In in the past 40 years, general time crops disaster area is 4,000 ten thousand~4,700 ten thousand hectares, and it is about 200,000,000 to be subjected to disaster to affect population, because of various natural calamity death toll from thousand to ten thousand people, and more than 500 hundred million yuan of direct economic losses.1989~1992 years 4 years, average annual loss are about 1/4 of 50,000,000,000 dollars of the whole world average annual losses of early 1990s.
(3) spatial and temporal distributions is wide, and the Areal Combination of disaster is obvious.The spatial distribution of China's natural calamity and Areal Combination thereof have very strong correlation with the area differentiation of nature and social economic environment.With regard to macroscopic view distributes, mostly occur the main separately cloth of the arid of spring, Qiu Liangji in the northwest, loess plateau and North China; The heavy rain, the flood that mostly occur in summer mainly are distributed in wide monsoon region, east, concentrate on 7 large river basins; Forest fire mainly is distributed in northeast and southwestern forest zone, mostly occurs at the Winter-Spring arid season; Earthquake mainly is distributed on the active structural zone in southwest, northwest and North China; Low temperature freezing-disaster and ice and snow disaster in the Qinghai-Tibet high cold current area particularly outstanding; Typhoon, storm tide mostly occur in the southeastern coastal areas.Southwest follows earthquake, heavy rain to cause that the cluster of landslide, avalanche, mud-rock flow and mountain torrents occurs.The spatial distribution of natural calamity also presents certain conjugacy.Change such as the power of, monsoon and to have caused drought in the north and flooding in the south or south drought north waterlogging, and area waterlog first rear drought or first waterlogging phenomenon after the drought.According to National Meteorological Bureau's statistics, the frequency on average occurs and shows a rising trend in various meteorological disasters, and be 19.56 the fifties in 20th century, and be 26.20 the sixties, reaches the eighties 28.18 times.
When the natural calamities such as earthquake, typhoon, heavy rain, severe snow occur, usually the ground Wireless Communication Equipment also can be damaged, thereby cause ground communication to interrupt, common land mobile communication terminal and some ground emergency communication private network system terminals can't be sent calling for help information, for rescue operation after the calamity has brought difficulty.This moment, satellite mobile communication system still can work, but it is larger to be based on the ICBM SHF satellite terminal volume, the present situation that communication cost is higher, and few people carry ICBM SHF satellite terminal.Like this in the face of the disaster of burst, trapped personnel still do not have effective means with own condition in damaged and position informing to extraneous, succour timely obtaining.
Therefore, when the satellite of combined ground portable terminal and ICBM SHF satellite terminal function and ground communication dual-mode terminal can effectively solve the ground communication interruption, can not receive and dispatch the problem of emergent message.Comprise earth module and satellite modules in satellite and the ground communication dual-mode terminal, because its satellite modules is according to complete satellite communication Functional Design, so the volume of satellite and ground communication dual-mode terminal is large, be inconvenient to carry that cost of manufacture is high.In addition, earth module and satellite modules are usually relatively independent, can not the intelligent suitable mode of selection process the emergency communication demand.
