Duration is the scrambling information of 1/50ms.Again such as issue formal message for the previous period, just tactile
Send out the transmission of scrambling information, to take this channel temporarily, and when usually being not required to send formal message, by this
Channel is released to the public, improves the service efficiency of channel.
Because of the transmission of above-mentioned active interference message, cause that the channel of first frequency is occupied, other are uncommitted
User cannot normally using this channel, thus use instead other channels communicated so that worked as receive formal
Need when releasing news, need can release news is converted into the wireless signal of first frequency and is propagated.Specifically
, need to release news mostly acoustical signal, or letter signal, inverted for current signal after, plus vibration
Device is modulated into high-frequency oscillation signal through d/a, is sent by antenna.
Receive formal need to release news, can be to directly receive to release news itself, caching or storage should
Information, the need being simultaneously converted into first frequency release news, and store this information and can also repeatedly send, such as
Need the occasion notifying in emergency information.Preferably, release news as shown in Fig. 2 receiving formal need,
Can the start message issued of leading trigger message.This start message is used for notifying broadcasting terminals to start just to report
Formula information, only receives active interference message before receiving terminal, does not notify broadcasting terminals to process, and receive
To after start message, receiving terminal notifies broadcasting terminals, the need of the first frequency being successfully received is released news and turns
Chemical conversion word is issued, or changes into acoustical signal and issued by power amplifier.
Preferably, this start message also may be used to indicate unlatching broadcasting terminals.Sometimes broadcasting terminals may not be in
The area of normally open, especially power supply shortage.After receiving terminal receives start message, open and report eventually
The power supply at end, or broadcasting terminals are waken up from resting state, broadcasting terminals then send out by start to process receiving terminal
The need of the first frequency sending release news, the report of style of writing of going forward side by side word, sound and/or image.
Preferably, before the need sending first frequency release news, first to receive instruction active interference and become
The feedback message of work(.When can be to receive to release news or receive the notice needing to release news here, etc.
Treat whether it receives feedback information, as is shown in phantom in fig. 3, this feedback information is derived from and receives first frequency master

Disaster early-warning information, such as tsunami, hurricane, earthquake, heavy rain to landslide or mud-rock flow danger give the correct time in advance,
By wired or optical fiber solutions, early warning information is notified emission center station at county level, the village that emission center station has under its command
Fall 1 be this disaster need take precautions against severely afflicated area.
It can be the active interference information of f1 by timing transmission frequency usually that emission center stands in, not same
In the case that frequency disturbs, the receiving station being located at village 1 can receive the active interference information that frequency is f1, but
Need not process and respond, thus emission center stand in usually be not required to grasp f1 channel whether taken by other people (
In another embodiment, the receiving station in village 1 receives the active interference information that frequency is f1, and periodically sends
Feedback signal, emission center stands in and usually grasps whether f1 channel is taken by other people).
This emission center station receives 24 hours futures company of will appear from of city-level emergency information distribution platform offer
The forecast of continuous heavy rain, transmission frequency is that the information of f1 issues start message, and starts intervalometer timing.Fixed
When device triggering can by information issue start message send triggering (also can by receive will have emergency information need
The notice issued triggering, receive this notice simultaneously also trigger message issue the transmission of start message).Setting
In fixing time, emission center station does not receive feedback message, then use the active interference message that frequency is f2 instead.
Through interference (persistent period relatively waits the time length of feedback message) after a while herein, center is sent out
Penetrate the information with frequency as f2 for the station to issue start message to trigger feedback message reception intervalometer, receiving
After feedback message, emission center station is passed through vhf/uhf antenna and is sent heavy rain early warning information with frequency for f2,
After the receiving station in village 1 receives early warning information, inform full village resident by the loudspeaker in village broadcasting station, to carry
Early carry out strick precaution and dredge.
Emission center station can be last in the formal information issued, and carries end of message mark, or individually sends letter
Breath end (can be null message null), to notify this section of early warning information to be all sent to village and to connect
Receive station.After receiving station of village receives end of message message, whole section of early warning information of caching is sent to broadcasting terminals.
Or, according to embodiment above, according to the important of early warning information or emergency level, emission center can be set
Station stores after need to releasing news, and sends this period early warning information at interval of a period of time and (is such as spaced

After whole section of early warning information, through being received again by the discernible master such as random number sequence or regular pulses after a while
Dynamic interference message, acquiescence early warning information receives, and is transmitted to broadcasting terminals and carries out the modes such as voice or word
Report.
Have jurisdiction over the less area of scope in county, disaster alarm typically need to cover all counties linchpin village, i.e. each village face
Face almost identical calamity source, emission center station at county level can carry out accounting for frequency using same frequency to having each village under its command
Issue with information.Feedback message sending module is integrated in emission center station at county level, if accounting for frequency success, letter
The start message that breath is issued is received by each receiving station of village 1 to village n, and receiving station can start broadcasting terminals,
Carry out the preparation of emergency information issue.The frequency that accounts for using same frequency is issued with information, also makes each village to week
The situation enclosing neighbouring village can have and more fully understands, to arranging scheduling advantageously.
If territorial scope is slightly wide, and more targeted information is needed to issue on geographical position, can be to not
With the different reception frequency range of village setting.Connect above example, transmission frequency is f3 simultaneously at emission center station
Or the active interference message of f4 is taking the channel and village 2 between, when needing to notify village 2, village 2
Receiving station start message is issued to the information for f3 and f4 for the frequency can process, open the wide of village 2
Broadcast loudspeaker go forward side by side row information report.In the same manner in receiving station and the broadcasting terminals of village n.This example is equally applicable to
The information issuing system of similar networking structure.
Again so that information receiving device is as mobile device as a example, such as mobile handss platform, needing field or even depopulated zone
It is convenient for carrying in the environment of operation, report equipment and information receiving device are integrated on a hardware.In order to save
Save electricity, the state that report equipment is on ordinary days in standby dormancy or closes power supply, only receive in information receiving device
To information issue start information when, just will report device activation.
Hold the staff of mobile handss platform, can be according to the emergency notice of information distributing apparatus, such as cold wave is pre-
Alert, or the warning of front minefield, withdraw from danger zone in time.Because signal can be decayed with distance, information is issued
(microwave transmission) is transmitted for direct wave, if only need to be public in diameter tens between equipment and information receiving device
In even more a small range propagate, information distributing apparatus can pass through controlling transmission signal power, allow a small range
Receiving device receives information.So, through the decay of signal, the information distributing apparatus outside hundreds of kilometer and
Even if about between the information receiving device in kilometer, can be communicated using this frequency simultaneously, significantly be carried
High channel service efficiency.
Various radio traffics are defined by " radio frequency divides regulation " of China, and to right
The radio frequency answered is divided and has been assigned, and in the terrestrial broadcasting of wireless signal, typically adopts microwave to pass
Defeated, have focused largely on superfrequency (uhf) 300-3000mhz or very high frequency(VHF) (vhf) 30-300
Transmit in the frequency range of mhz.But the scene of the present invention other signal waves equally applicable transmission, such as hyperfrequency
(shf) or extremely high frequency (ehf) signal transmission, as long as be normal service needed, referred to
Join and carry out legal accounting for frequently for the frequency range that can use.
Although preferred embodiments of the present invention have been described, but those skilled in the art once know base
