The Analysis And Testing About The Disaster-tolerant System For Emergency Communication

In recent years, The earthquake always happened in worldwide, like WenChuan earthquake, Haiti earthquake, Chile magnitude quake, Taiwan Kaohsiung earthquake, and YuShu earthquake, all of there earthquake bring series natural disasters such as mud-rock flow , typhoon, flood, and more, Not only all kinds of inconvenience caused, but also Government undergo a terrible ordeal, at the same time, all kinds of communication system were damaged badly, the ground communication were interrupted completely, It made the disaster area became information island, people cannot connect with their friends, family member, It also influence government relief work to spread quickly, as we all known, the communication is very import for others to rescue, smooth communication can save lots of rescuing time and save more life, this article will suggest to set up a tolerant emergency communication safeguard system, make sure people in emergency can resort effectively and timely and government can provide more help in time ,but for our existing communications system which were not doing well in 2008 the WenChuan earthquake, so keeping security information flow is principal settlement problem for the disaster area, based on this kind of circumstance, set up an emergency communication safeguard system are more import and necessary.The main reason of causing the mobile communication network and external interruption is external backbone transmission link interrupted completely. In our country's existing communications system, transmission cable rely on the lineate light path mainly, although armored fiber optic cable and other protective measures are existing at present, but when the earthquake or other kinds of natural disaster were coming, even reinforcing steel houses were emaciated, armored cable fiber were more fragile, So this article would like to change transmission mode, starting with increasingly mature the satellite transmission technology as emergency communication of the basic means to illustrate and will tell you how to construct a communication safeguard system, ensure the daily life of people more convenience.This article will start from the general meaning of emergency communication, giving the detailed introduction of the concept of emergency communication after, by comparing the emergency safeguard communication with the traditional communications, and concluded that the difference between the related requirements, makes a detailed analysis about emergency safeguard communication and emergency communication related demand , from the requirements phase and demand exactly etc, starting on how to set up and analyzed a set of emergency communication safeguard system, and formulate emergency communication system construction principle, put forward the development strategy of emergency safeguard system Suggestions, etc.This article also introduce according how to deploy a satellite transmission emergency station and take an example with GuangDong province, analyzed how to regional deployment of satellite transmission emergency station and provide some station layout experience, in addition, in the article also combine with some of the typical natural geographical conditions in our country, and earthquakes, floods, debris flow disaster etc, give the suggest how to carry out the system of operation, together with the training.And summarize the communication security system effectiveness and applicability, at the same time, put forward future development of communication safeguard system of some Suggestions and prospect.This article combine the theory discussing and practice of the communication, make the construction and strategy about the communication safeguard system , although real implementation may need our telecommunication operators, and communication manufacturer collaboration, also need the national related departments to formulate relevant regulations, etc., but the author believe, as long as emergency communication have been set up completely ,it will bring more and more convenience for people's life and disaster area, to establish a set of air and ground of combining the three-dimensional emergency communication system and make the emergency communication safeguard system more perfect.
