The embodiment of the present invention is by before using a certain frequency to carry out radio communication, take the lead in sending active interference information, make improper use or have no right to use user or the equipment of this frequency channels, because its communication channel can't be normally used and be switched in interference, avoided having the right or just when using this frequency to carry out the problem of co-channel interference of equipment when releasing news of radio communication, need release news to be received the timely and correct reception of terminal.
Below in conjunction with Figure of description, the embodiment of the present invention is described in further detail.
Shown in Figure 1, the method for the information issue that the embodiment of the present invention provides releases news need and propagates by the mode of wireless signal, and the method comprises the following steps:
Send the active interference message of first frequency;
Reception need release news, and the need that are converted into first frequency release news;
The need that send first frequency release news.
Wherein, send the active interference message of first frequency, can continual mode send, active interference message is the formal message required frequency (herein be first frequency) of frequency for needing issue of scrambling signal, to take this channel.Preferably, can preset the time interval that sends active interference message, the lasting duration of transmission of setting and/or the transmission opportunity of setting.Such as sending a string scrambling signal every 50ms, can be the one group of random sequence that is generated by tandom number generator, or regular pulses.Be the scramble information of 1/50ms such as sending lasting duration every 10ms.Such as a period of time before the formal message of issue, just trigger the transmission of scramble information again, take this channel temporarily, and in the time usually need not sending formal message, this channel is discharged to the public, improve the service efficiency of channel.
Transmission because of above-mentioned active interference message, cause the channel of first frequency occupied, other uncommitted users can't normally use this channel, thereby use other channels instead and communicate, make when receiving that formal need release news, the wireless signal that is converted into first frequency that need can be released news is propagated.Concrete, need release news mostly is voice signal, and perhaps letter signal, after being converted into current signal, adding oscillator and be modulated into high-frequency oscillation signal through D/A, sent by antenna.
Receiving that formal need release news, can be that direct reception need release news itself, buffer memory or store this information, and the need that are converted into simultaneously first frequency release news, and storing this information can also send repeatedly, such as the occasion that need to notify at emergency information.More excellent, as shown in Figure 2, receive that formal need release news, in advance the start message of trigger message issue.This start message is used for the notice broadcasting terminals and begins to report formal information, be that receiving terminal receives only active interference message before, do not notify broadcasting terminals to process, and after receiving start message, receiving terminal notice broadcasting terminals, the need of the follow-up first frequency of receiving are released news to be changed into word and issues, or changes into voice signal and issue by power amplifier.
More excellent, this start message also can be used for indication and opens broadcasting terminals.Sometimes broadcasting terminals may not be in normally open, especially the area of power supply shortage.After receiving terminal is received start message, open the power supply of broadcasting terminals, perhaps broadcasting terminals is waken up from resting state, release news so broadcasting terminals begins to process the need of the first frequency that receiving terminal sends, the report of style of writing word, sound and/or the image of going forward side by side.
More excellent, before the need that send first frequency release news, first to receive the feedback message of indication active interference success.Here can be to receive in the time of need releasing news or receive the notice that need to release news, wait for whether it receives feedback information, as shown in the dotted line of Fig. 3, this feedback information be from the receiving terminal that receives first frequency active interference message.If receive feedback information, the need that will the receive need that are converted into first frequency that release news release news, otherwise continue to send the active interference information of first frequency, until receive feedback information, just transform.Can be also regularly to send active interference message, regularly receive the feedback message of active interference success, as receiving feedback information in Fig. 3 not necessarily receive need release news after, but one fix on the need that are converted into first frequency and received feedback information (regularly feedback or trigger feedback) before releasing news.
Or the start message that sends is first frequency, triggers the opposite end and sends feedback message.The opposite end is for receiving the start message receiving terminal herein.If active interference is success not, namely should issue the channel that need release news occupied, due to the co-channel interference of two signal sources, the receiving terminal that need release news can not receive correct need and release news.Can keep in the need that receive release news this moment, continues to send active interference message and account for frequently, until receive the feedback message of indication active interference success, the need that just begin to send first frequency give out information.
The opposite end that receives start message can be positioned at the receiving terminal that need release news, and start message was used to indicate simultaneously and opened broadcasting terminals or indicate broadcasting terminals to begin to report this moment.The opposite end that receives start message also can be arranged in the equipment of information issue, and this moment, start message was arranged in the feedback signal transmitting element of information distributing apparatus equally for triggering, and broadcasting terminals mostly is normally open.
If within the time of setting, do not receive the feedback message of indication active interference success always, except continuing to send the active interference message of same frequency, also can switch to another frequency and account for frequently.Such as using at the beginning second frequency to send active interference message, when not receiving the feedback message of indication active interference success in setting-up time, switch to first frequency and send active interference message, then receive the feedback message of indication active interference success, then the need that will receive release news and are converted into first frequency and send.
Again for example, use at the beginning second frequency to send active interference message, when receiving the notice that needs the formal information of issue, send the start message of second frequency, to trigger the transmission of feedback message, when not receiving feedback message in setting-up time, switch to first frequency and send active interference message, send again the start message of first frequency after after a while, to trigger the transmission of feedback message.Receive the feedback message of indication active interference success this moment, then the need that will receive release news and are converted into first frequency and send.Radio frequency in China is divided regulation, or in the radio regulation(s) of International Telecommunication Association, important public information, such as propagation channel emergent, early warning information, perhaps military or police channel, all ratified the frequency band (its bandwidth equals the twice that necessary bandwidth adds the frequency tolerance absolute value) launched, if fail to launch in the centre frequency of this frequency band, also can be in select transmit frequency around centre frequency.Generally, transmitting station transmits, except the main channel frequency, also supplemental channel frequency arranged, and the method for available similar frequency hopping herein, selective channel in the bandwidth range that is assigned with, the timely transmission that assurance need release news.
The embodiment of the present invention also provides a kind of equipment of information issue, as shown in Figure 4, comprises with lower module:
The active interference message transmission module is used for to the active interference message of receiving terminal transmission first frequency;
The information interface module be used for to receive and need release news, and need are released news is transmitted to information issue primary module; And
Information issue primary module, the need that are used for reception information interface module forwards give out information, and the need that are converted into first frequency release news and send to receiving terminal.
Above-mentioned active interference message transmission module comprises active interference message control unit and active interference message sending unit.The active interference message control unit is controlled the transmission frequency of active interference message sending unit, such as sending scramble information with first frequency or second frequency.Further, the active interference message sending unit sends lasting duration and/or the transmission time interval of scramble information, is also adjusted by sending control information by the active interference message control unit.For example, at the issue channel of other height emergence messages such as emergency information, continue transmission active interference message or interval transmission active interference message and continue to account in application scenarios frequently comparatively applicable.Perhaps, control by the active interference message control unit opportunity that scramble information sends, for example, will send formal need release news before a period of time trigger the active interference message control unit, comparatively applicable in the issue of weather forecast information, the non-height emergence message such as military or police or transmission.
The information interface module is the external interface of this information distributing apparatus, is used for receiving the need that external information promulgating platform (shown in outside the empty frame of Fig. 4) sends and releases news, and be transmitted to information issue primary module.Whether detection need release news by reliable sources, can be by external information promulgating platform by keyword being set or alternate manner is identified, or carry out encryption after identification, also can carry out examination and judgement according to the rule of setting by the information interface module, or determine to be encrypted after authentic and valid, the need of authentic and valid or need to be keep secret are released news is transferred to information issue primary module.
The need of information interface module forwards give out information and mostly are sound or text formatting, also might be picture format, and information issue primary module is translated into the radio signal of first frequency, sends by antenna.
In a preferred embodiment as shown in Figure 5, the equipment of this information issue further comprises the start message sending module, be used for need at first frequency release news be sent out before, to the start message of receiving terminal transmission information issue.
The embodiment of corresponding information receiving device, comprise the receiving element that need release news with it, and the need that are used for the reception first frequency release news, and send to broadcasting terminals to carry out the information issue; With the start information receiver module, after the start information of receiving the information issue that information distributing apparatus sends, open broadcasting terminals, or the indication broadcasting terminals begins report.
In this embodiment, the information interface module of the equipment of information issue is further used for, receiving when need release news (but buffer memory or store this and need release news) simultaneously, perhaps when receiving the notice that to issue formal information, indicate the start message of start message sending module transmission information issue.
The start information receiver module of information receiving device is received the start information of information issue, identify this start information and be different from the active interference message that receives before, so the notice broadcasting terminals is carried out formal information and is reported preparation, perhaps receiving terminal just activates the broadcasting terminals in dormancy, or opens the power supply of broadcasting terminals.
In another embodiment of information receiving device, when information issuing system does not provide the notice of start message as the log-on message issue, the equipment that is the information issue does not comprise in the scene of start message sending module, the need of the information receiving device receiving element that releases news is first identified the wireless signal of the first frequency that receives, if the sequence of rules that random number sequence or sending and receiving both sides reach an agreement, active interference message identification module is identified as active interference message.If not this type of message, the receiving element that need release news is identified as the formal message that need give out information with it and reports by broadcasting terminals.
Broadcasting terminals can for the broadcasting equipment (as loudspeaker) in broadcasting station, wireless interspeaker, mobile hand platform, wireless colony terminal equipment or other bands show or the wireless terminal of sounding etc., in the situation that mountain area or field lack electric power or power failure (can use storage battery under extreme case) occurs, by dormancy or close power amplifier unit and save electric power, in receiving terminal notice or when opening broadcasting terminals, broadcasting terminals is with the release news conversion or be reduced into the information such as sound, word and issue of the need of first frequency.In some occasions, broadcasting terminals and above-mentioned information receiving device are integrated on a whole hardware facility, this hardware set reception antenna, detection/demodulation, reproduction, power amplifier, sounding or be shown in one, as this section beginning for example.
In another preferred embodiment, the equipment of this information issue further comprises the feedback message receiver module, after being used for receiving the feedback message of indication active interference success, sends enabling signal to information issue primary module.After information issue primary module is received this enabling signal, the need need that are converted into first frequency that give out information are released news and send to receiving terminal.
If active interference success, active interference message successfully received by the recipient of active interference message, and beam back feedback signal, if the feedback message receiver module is received this feedback signal, can indicate that first frequency place channel can be as the information issue.Only receive enabling signal, information issue primary module just releases news to the need of information interface module forwards and carries out actual treatment, like this, information issue primary module could successfully will need the information of issue to issue receiving terminal, more can avoid the mistake of important or emergency message to send out and leak and send out.
The embodiment of the information receiving device corresponding with above-mentioned information distributing apparatus comprises the receiving element that need release news, and the need that are used for the reception first frequency release news, and sends to broadcasting terminals to carry out the information issue; And:
The feedback message sending module comprises Interference Detection unit and feedback message transmitting element;
Wherein, the Interference Detection unit, when being used for the start message when the information issue of the active interference message that successfully receives first frequency or first frequency, notice feedback message transmitting element;
Wherein, the feedback message transmitting element when being used for receiving the successful reception notification of Interference Detection unit, sends feedback message; The success of feedback message indication active interference.
Further, if do not receive feedback signal within special time, the feedback message receiver module of information distributing apparatus can notify active interference data publish module to switch the frequency of scrambling signal.In the preferred embodiment that comprises the active interference message control unit, feedback message receiver module notice active interference message control unit also can change active interference message control unit interference duration before or the interval of scramble information transmission (such as duration increases, reduce at the interval or cancel the interval) this moment.Such as active interference message after second frequency switches to the first frequency certain time length, receive that (perhaps active interference message is sent out the information issue start message of first frequency to feedback signal again after transmission a period of time, start the transmission of feedback signal), at this moment just can log-on message issue primary module, and the information of carrying first frequency on indication information, make information issue primary module that need are released news and convert first frequency information to and issue.
The recipient of active interference message can be the submodule that the equipment of information issue itself comprises, and can be also the receiving terminal that the need of first frequency release news.
First embodiment that obtains thus is that the equipment of information issue further comprises the feedback message sending module, comprises Interference Detection unit and feedback message transmitting element;
Wherein, the Interference Detection unit is used for notifying the feedback message transmitting element when successfully receiving the active interference message of first frequency; When the feedback message transmitting element is used for receiving the successful reception notification of Interference Detection unit, send the feedback message of indication active interference success to the feedback message receiver module.
Second embodiment that obtains thus is, information receiving device further comprises the feedback message sending module, comprise Interference Detection unit and feedback message transmitting element, the function of each unit is the same, also communicates by wireless mode with feedback message receiver module in the equipment of information issue.Difference is, first embodiment can realize closed loop feedback in the inside of the equipment of information issue, when the operating frequency of active interference message can not make it successfully take at operating frequency place channel, in time adjust the operating frequency of active interference message, and send the important information that needs formal issue with this frequency.And transmitting only needs small-power to get final product, even can be after the feedback message of receiving the active interference success, and the power amplifier of restarting transmitter carries out formal communication.

Do not go to detect whether successfully receive active interference message, information receiving device only when successfully receiving the start message of transmission information issue, sends feedback message.If do not receive this feedback message in feedback message receiver module setting-up time, the indication continuation sends with frequency active interference message and accounts for frequently, the start message that again sends same frequency after after a while detects, by whether receiving that feedback message judges whether successfully to account for frequently; Perhaps the active interference message of another frequency of indication switching accounts for frequently, the start information that again sends this another frequency after after a while detects, after receiving feedback message, the ability log-on message is issued primary module, makes it use this another frequency that need are released news and sends.This moment the start message sending module can with the direct communication of feedback message receiver module, perhaps not with the direct communication of feedback message receiver module, and the start message of notifying the start message sending module to send new frequency by the information interface module, namely shown in the dotted line in Fig. 6.
A kind of information issuing system that the present invention also provides comprises apparatus embodiments and information receiving device embodiment that above-mentioned information is issued, and the combination of broadcasting terminals.
In one embodiment, in information issuing system, the equipment of information issue comprises active interference message transmission module, information interface module, information issue primary module.Further comprise the start message sending module, be used for starting broadcasting terminals by information receiving device, or the announcement information receiving equipment, prepare to begin to receive the formal information that needs issue.
Perhaps further, the equipment of information issue comprises the feedback message receiver module.Accordingly, information receiving device comprises the feedback message sending module, regularly sends feedback message when receiving active interference message, points out successfully to account for frequently, perhaps the active interference message of receiving is not processed, only send again feedback message when receiving the start message of information issue.In a preferred embodiment, the feedback message receiver module notifies the active message sending module to continue to send with frequency scramble information according to whether receiving feedback message within setting-up time, or notice active message sending module switching frequency sends scramble information.Between feedback message receiver module and feedback message sending module, detailed interactive mode is mentioned in the above-described embodiments, repeats no more herein.
Whether in the embodiment of another information issuing system, the equipment of information issue comprises feedback message receiver module and feedback message sending module, carries out radio communication by antenna between both, taken by self in order to the channel that detects a certain frequency.
In the embodiment that does not have start message to send, active interference information is random sequence or sequence of rules, perhaps carries other signs that can be identified by information receiving device, but does not need further processing.Like this, when beginning to issue formal information after the feedback message receiver module is received feedback message, information receiving device also can identify the difference between useful information and active interference information, thereby begins to process useful information and reported by broadcasting terminals.
In the embodiment that comprises the start message sending module, active interference information need not to be done further processing by information receiving device, only when information receiving device is received the start message of information issue, the triggering receiving element that need release news is started working, broadcasting terminals or be activated (from resting state) or start is reduced into sound with wireless signal or word is reported.
Take the delivery system of emergency information as example, as shown in Figure 7, all there is the emergency information distribution platform of self in emergency information issuing unit at the same level (as weather bureau, water conservancy bureau, seismological bureau etc.) provincial, prefecture-level and at county level, can join by the network of special use between these platforms and (at county level) cell site, center and carry out networking, adopt the access way of wired, wireless or optical fiber.The equipment of information in above-described embodiment issue i.e. cell site, center herein.Be provided with the information interface module in the cell site, center, when information promulgating platform at different levels need to be issued emergency information through decision-making, all can directly need the emergency information (such as the emergency information issue page of logining the cell site, center carries out data publish) of issue to the transmission of cell site, center, also Ke Jing province-ground/city-county is transferred to the cell site, center step by step.
Active interference message transmission module in the cell site, center, the duration that the time interval that can self set and/or transmission continue sends scramble information, also can be subjected to the indication of the control information of emergency information distribution platforms at different levels, send scramble information with the time interval and/or the lasting duration of transmission of setting.
When the information interface module is received the message that needs issue, notice active interference message transmission module ends to send active interference message to abdicate channel, and notice start message sending module sends start message, be used to refer to receiving terminal and open broadcasting terminals, or the need that make broadcasting terminals begin to report through being converted into first frequency release news.
Fig. 8 has showed the prealarming process of a natural calamity, the system of the information issue that the embodiment of the present invention of having used Fig. 7 to show provides.When provincial or city-level emergency information distribution platform are obtained serious and abominable natural calamity early warning information, as tsunami, hurricane, earthquake, heavy rain to the landslide or mud-rock flow danger give the correct time in advance, notify cell site, center at county level by wired or optical fiber mode with early warning information, the village 1 that the cell site, center has under its command is the severely afflicated area that this disaster need to be taken precautions against.
The cell site, center can be the active interference information of F1 by the timed sending frequency usually, in the absence of co-channel interference, the receiving station that is located at village 1 can receive that frequency is the active interference information of F1, but need not to process and respond, so whether the cell site, center is taken (in another embodiment by other people usually need not grasping the F1 channel, the receiving station in village 1 receives that frequency is the active interference information of F1, and regularly send feedback signal, whether the cell site, center is taken by other people usually namely grasping the F1 channel).
The forecast that 24 hours futures will occur continuous rainstorm that city-level emergency information distribution platform provides is received by this subcenter cell site, and transmission frequency is the information issue start message of F1, and starts the timer timing.The triggering of timer can be sent triggering (also can be by receiving that the notice with there being emergency information to issue triggers, receive the also transmission of trigger message issue start message simultaneously of this notice) by what information was issued start message.In setting-up time, feedback message is not received by the cell site, center, and using frequency instead is the active interference message of F2.
Through interference (duration waits for that the time of feedback message is long) after a while herein, the information issue start message of cell site, center take frequency as F2 triggers feedback message and receives timer, after receiving feedback message, the cell site, center sends the heavy rain early warning information take frequency as F2 by the VHF/UHF antenna, after early warning information is received by the receiving station in village 1, inform full village resident by the loudspeaker in broadcasting station, village, take precautions against and dredge in order to carry out ahead of time.
The cell site, center can be last in the information of formal issue, and carry information finishes sign, or sends separately end of message message (can be null message Null), notifies this section early warning information all to send to village receiving station.After end of message message is received by village receiving station, whole section early warning information of buffer memory sent to broadcasting terminals.Perhaps, embodiment according to the front, important or emergency level according to early warning information, can arrange the cell site, center stored need release news after, send this period early warning information (such as the interval sent once in 10 minutes at interval of a period of time, send altogether six times), send at last ending message.Also or, after whole section early warning information received by village receiving station, again receive the discernible active interference message such as random number sequence or regular pulses through after a while, the acquiescence early warning information receives, and is transmitted to the report that broadcasting terminals is carried out the modes such as voice or word.
In the less area of linchpin scope, county, disaster alarm generally need cover all linchpin villages, county, and namely each village faces almost identical disaster risk, and cell site, center at county level can use same frequency to account for frequently and the information issue to having each village under its command.The feedback message sending module is integrated in cell site, center at county level, if account for frequently success, the start message of information issue received by each receiving station of village 1 to village N, and receiving station can start broadcasting terminals, carries out the preparation of emergency information issue.Use accounting for frequently and the information issue of same frequency, also make each village can have more fully the situation of neighbouring village on every side and understand, more favourable to arranging to dispatch.
If territorial scope is slightly wide, and need information issue more targetedly on the geographical position, can different reception frequency ranges be set to different villages.Connect the example of face, the cell site, center simultaneously transmission frequency be the active interference message of F3 or F4 take and village 2 between channel, when needing notice village 2, the receiving station in village 2 can process the information issue start message that frequency is F3 and F4, opens the loudspeaker in village 2 and carries out the information report.In like 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.
Be example take information receiving device as mobile device again, as mobile hand platform, even be convenient for carrying under the environment of depopulated zone operation in the needs fields, report equipment and information receiving device are integrated on a hardware.In order to save electric weight, report equipment is in the state of standby dormancy or powered-down on ordinary days, only when information receiving device is received the start information of information issue, just will report device activation.
The staff who holds mobile hand platform can be according to the emergency notice of information distributing apparatus, such as the cold wave early warning, or the caution of minefield, the place ahead, in time withdraw from the danger zone.Because signal can be decayed with distance, be direct wave transmission (microwave transmission) between information distributing apparatus and information receiving device, if only need tens kilometers of diameters even more among a small circle in propagation, information distributing apparatus can be by controlling transmitted signal power, allow among a small circle in receiving equipment receive information.Like this, through the decay of signal, even the information distributing apparatus outside the hundreds of kilometer and around it between information receiving device in kilometer can use this frequency to communicate simultaneously, greatly improved the channel service efficiency.
" radio frequency is divided regulation " of China, various radio traffics are defined, and the radio frequency of correspondence division and assignment have been carried out, terrestrial broadcasting at wireless signal, general adopt microwave transmission, mostly concentrate on the frequency range of superfrequency (UHF) 300-3000MHz or very high frequency(VHF) (VHF) 30-300MHz and transmit.But the scene of applicable equally other signal waves transmission of the present invention, for example transmission of hyperfrequency (SHF) or extremely high frequency (EHF) signal so long as be normal service needed, is carried out the legal frequency that accounts for and is got final product being assigned as operable frequency range.
