Description
Technical field
The utility model relates to the urgent Public Address system of disaster field.
Background technology
The earthquake, flood, storm, volcano, the tsunami, freezing that more and more take place frequently, and under cosmic ray or the extreme disaster scenarios it such as terrorist attacks satellite, network, often as Chinese Wenchuan earthquake in 2008, Chinese Yuyao floods in 2013 ... power-off, suspension, open close letter, broken string road, break off a friendship logically, all advanced communications facilitys such as existing network, phone, TV are not brought into play effect substantially.The people that usually highly rely on modern high technology just seem helpless especially in face of natural calamity in this case! Blank out in people's brain, each responding agencies of government also feels unable to do what one wishes ... now, how to carry out in order rational command scheduling, various action indication informations are informed in time and interspersed among the disaster area helpless numerous common people everywhere, to avoid anxiety fear, to build up confidence, avoid confusion and turmoil ... reach farthest mitigation, the disaster relief and save oneself?
Famous Crisis expert Michael Regester is pointed out: in the time that tissue faces a crisis, whenever all seem than usual even more important with communication and the propagation meeting of relevant public.So, now should take which type of channel could reliably pass on disaster emergence message?
Make a general survey of present various public means of communication, the Internet architecture is the most complicated, high to countless intermediate equipments and circuit/optical fiber interdependency, having a power failure, broken string, hacker is terrified while attacking is the most slippery; Mobile communication system structure is also very complicated, middle wired/fiber optic network link is extremely many, is easy to cause that information is stopped up, equipment damages and can not effectively issue voice messaging in the time of incident; And present TV basic development become wired system, intermediate equipment and circuit are also extremely many.How is " village of village rings " " typhon " broadcasting engineering of just carrying out in Chinese countryside at present? they must manually be opened and could not have a power failure, and also must rely on the Internet! Above various supply lines, communication line and optical fiber are easy to be destroyed and cause systemic breakdown in the time that the disaster such as earthquake, storm, big flood, volcano and the attack of terrorism occurs as everyone knows! How is intercom so? regrettably this local message that can only be used for rescue personnel and commanding exchanges, and can not be used for disaster area victims of the disaster's large area and convey a message.
But we find, existing radio platform broadcast is a kind of universal and the most simple and reliable system of structure does not need intermediate link, does not also rely on satellite, and structure and the work in each radio station have independence, are suitable in emergency circumstances highly reliable broadcast.This has fully shown its unique feasibility in the Wenchuan earthquake disaster relief, and " broadcast " becomes one " continual lifeline forever ".But regrettably not subsidiary urgent broadcast status signal in this broadcast singal, its receiving terminal---broadcast receiver can only lean on Artificial Control, cannot realize burst and in emergency circumstances automatically open.
Obviously, as long as solve how reliably automatically start (accurately, reliably, start fast, and effectively opposing is terrified attacks) and be how the link of public's reception, this radio broadcasting---the simplest, the most original communication technology, in the time of burst fire-disaster, will become unique technology that can rely on, and make full use of the broadcasting station resource of the various places that distribute, directly take into account and hold wireless part crowd, and rural area, the part crowd that the public broadcasting facilities such as community cover, can be directly between each broadcasting station network with the reliable audio conversion broadcast mode of simple and fast the most, realizing effectively unified command scheduling and information issues.
On the other hand, not common people have broadcast receiver, and in fact most situations are that old man likes to listen to the radio at present, and some people listens vehicle-mounted radio.In the situations such as mountain torrents, earthquake, volcano, the attack of terrorism, have little time often early warning, also not free broadcast receiver is taken with oneself, and must have before the accident happened also movable or work out of doors of quite a few people, also can not be with it also with broadcast receiver.Therefore, obtain government's the condition of a disaster information by broadcast receiver listening to audio broadcasting station, can only solve the problem of few some people.To solve the public victims of the disaster's needs of problems just very and fundamentally, only have and set up automated wireless public broadcasting terminal by this broadcasting station in each area, for guaranteeing that high reliability also must receive all band signals such as frequency modulation, medium wave, shortwave, long wave, and covering whole disaster areas with the form of remote wide-angle typhon or similar loudspeaker, the voice messaging that just can at once early warning, alarm and action be guided directly conveys to the victims of the disaster.
Obviously, frequency modulation, medium wave, shortwave, long wave and amateur band, frequency band covers extremely wide, not only can cover nearly all general radio communication channel, in the time that disaster, even extensive electromagnetic interference occur total some can proper communication, have very high reliability, in addition, these frequency bands also can be easy to realize emergent transmitting by mobile model, pocket transmitter.
At present, even if the existing emergency system as the U.S., Japan also can only realize early warning system function, and can only utilize conventional media distribution information and utilize special siren to send alarm signal (but can not issue voice messaging), cannot after disaster occurs, also guarantee reliably to use---because this system depends on cable network and mains supply, but also must guarantee that user has opened power supply.
Finally, distinct with other industry equipment, after this individual system is built up, must carry out key one use after continuous maintenance just can be guaranteed for many years! Due to its distribute wide especially, install that landform is extremely various, quantity is huge especially, stand-by time is long especially, its regular maintenance just becomes the engineering of a very arduous and cost.Therefore, must seek modern high technology and solve this difficult problem, could just really allow this emergency system possess practicality and promotional value.
Hence one can see that, objectively urgently a kind of based on existing radio broadcasting radio station, be not afraid of power failure, be not afraid of suspension broken string, there is the burst fire-disaster emergency wireless Public Address system of high reliability, it must be at any time receives reliably emergent coded signal from public's radio broadcasting radio station of existing each wave band and/or interim transmitter, and fast automatic startup is devoted oneself to work, with the public broadcasting form (and being not limited only to individual broadcast receiver or television set or mobile phone) of the remote radiation typhon of wide-angle, by the early warning from government emergency department, the voice messaging that alarm and action are guided directly and is forcibly broadcast to all victims of the disaster, and networking and using method must be simple and reliable, in conjunction with national conditions, fully share existing resource, instead of duplicate removal is built or reconstruct on a large scale existing radio platform, with fast, low cost completes emergency system construction, and must take modern special technology will to be distributed in the whole nation significantly to reduce, maintenance difficulties and an expense of the huge especially wireless public broadcasting terminal of quantity!
