Abstract
The invention discloses a kind of method and information processor of broadcast message, it is characterized in that being modulated on the frequency modulation negative carrier and launching via broadcast transmitter with behind the information coding encrypting.Subscriber computer can in real time, uninterruptedly receive these information via information processor, and does not need expensive private wore network network, is suitable for exchanging of information such as stock exchange, financial market, forward price, electronic newspaper, magazine and mail.
Description
What the present invention relates to is a kind of method and processing unit thereof of broadcast message, is suitable for transmitting and receiving of RI radio intelligence.
Our world is just experiencing the huge explosion of information, and hundreds of millions information were confusingly to stepping on when every day was per, and how scientifically and rationally collection, good these information of processing and utilizing have major and immediate significance.
At present, the interchange of information has methods such as broadcasting, TV, newspaper, phone, fax, fax, computer networking in the world.The cost that these methods have is low, the cost height that has; What have is non intelligent, the intellectuality that has; The easy preservation that has, the difficult preservation that has; The real-time that has is good, and the real-time that has is bad.As broadcasting, cost is low, real-time good, but the information of receiving also need write down and could preserve.Newspaper and for example, cost is low, but real-time is poor.Computer networking for another example, real-time is good but with high costs.
For overcoming the shortcoming of above these information exchange methods, the purpose of this invention is to provide that a kind of to have real-time good, cost is low, the method for intelligentized broadcast message and information processor.
For realizing above-mentioned task, solution of the present invention is referring to accompanying drawing 1.Form by broadcast message platform and user terminal two large divisions.
The broadcast message platform is made of compound pair of carrier modulator of information input terminal (1) information station's central computer (2) (3) blender (4) and frequency-modulated broadcast transmitter (5).
The information of information input terminal (1) typing, enter the treated layout encryption of information station's central computer (2) and add subscriber-coded, form serial data stream compound pair of carrier modulator of input (3) in compound pair of carrier modulator, after serial data stream is modulated the carrier wave of different frequency for the first time, this carrier wave is that the carrier wave of paying of 67KHZ carries out frequency modulation(FM) to frequency again for the second time, forming modulated pair of carrier wave enters in the blender (4) with after normal broadcast program mixes again, to the radio frequency carrier modulation, launch by frequency-modulated broadcast transmitter (5) at last for the third time.This shows that in fact information is just launched after being modulated by three times.Therefore, the confidentiality of information is high, adds in information station's central computer and information encryption is handled, the extremely difficult steal information of disabled user.
The user sends in the subscriber computer (7) again and further analyzes, handles, stores after receiving and handle these information by information processor (6).
Because the present invention has adopted radio broadcasting in conjunction with computer technology, do not need expensive private wore network network, can carry out real-time information service to a large amount of users, can be widely used in the interchange of information such as stock exchange, financial market, forward price, electronic newspaper, magazine and Email.
Enforcement below in conjunction with 2 pairs of information processors of the present invention of accompanying drawing is described in further detail.
Information processor of the present invention (6) is by group amplifier (8), compound demodulator (9) microprocessor (10) user's autocoding converter (11) memory (12) battery (13) voltage detecting charge controller (14) mains switch (15) D/A(16) audio frequency amplifies (17) and forms, they are manufactured into a computer card, can directly insert in the subscriber computer (7).
Wherein group amplifier comprise that height is put, frequency conversion, in put; Compound demodulator (9) comprises first intermediate frequency (10.7MHZ) demodulator.Second pair of carrier wave (67KHZ) demodulator and data flow demodulator; User's autocoding converter (11) is made up of the flash memory access circuit, and their conversion can be by information station's central computer (2) remote control.Information station's central computer (2) sends and revises the order of user's autocoding when needed.After microprocessor (10) is confirmed, send into user's autocoding converter (11) and carry out subscriber-coded conversion.
Information station's central computer (2) is through frequency-modulated broadcast transmitter (5) emitted radio signal, after the antenna of information processor (6) enters group amplifier (8) amplification, by compound demodulator (9) demodulation, compound here demodulator (9) is corresponding to compound pair of carrier modulator (3), for the first time to intermediate frequency 10.7MHZ carrier wave demodulation, the unnecessary signal of elimination obtains the carrier signal of paying that frequency is 67KHZ bandwidth ± 8KHZ, to obtaining warbled signal after this signal demodulation, for the third time warbled signal demodulation is obtained serial data stream for the second time.Entering microprocessor (10) compares with user's autocoding converter (11), confirm whether send to oneself, if then send in subscriber computer (7) or the memory (12), under suitably software cooperates, to the information that receives classify, analyzing and processing.
Information station's central computer (2) is when sending information, if user computer is in off-mode, message handler (6) power supply is powered by the battery that carries (13), the information that receives is temporarily stored in earlier in the memory (12), after information is filled memory (12), microprocessor (10) output signal control mains switch (15) is opened the power supply of subscriber computer (7) automatically, and deposits information in the back powered-down.
When battery (13) brownout, battery (13) is charged by the power supply that voltage detecting charge controller (14) detects and output signal control mains switch (15) is opened subscriber computer (7) automatically.Owing to battery (13) and voltage detecting charge controller (14) are arranged, make subscriber computer (7) the whole day start also can in real time, uninterruptedly receive information.
When important information transmitted, information station's central computer (2) sent specific coding, and after microprocessor (10) was judged, the output digital signal was through D/A(16) and audio frequency amplification (17) output sound, the user reminded.
