Description

Speech calling memorandum indicator

The utility model belongs to technical field of telecommunications, is a kind of voice paging Adversaria prompting machine specifically.

At present the beep-pager that uses has only two kinds of digital display type beep-pager and Chinese display type beep-pagers.Though the numeric type beep-pager can be realized need not the operator and get involved paging person and can direct control finish paging, exists paging information digitlization to show, a large amount of information is difficult to express, and the inconvenient paged person shortcoming of reading; Though the available Chinese of Chinese type beep-pager shows a large amount of information, information to display must be by operator's input of typewriting, and this just makes paging be got involved by the operator, has brought inconvenience for paging person and paged person.

The purpose of this utility model then is the problem at above-mentioned existence, and a kind of voice paging Adversaria prompting machine is provided, and it need not the operator and gets involved, and can use the language performance paging information, and this machine also has the Adversaria prompting function simultaneously.

The utility model technical solution:

A kind of by wireless receiving demodulation machine, microcomputer control circuit, the voice paging Adversaria prompting machine that sound-compound-circuit is formed, the CAS1 that it is characterized in that T6668 in the sound-compound-circuit, CAS2, CAS3, the CAS4 signal is 1,2,4,5 pin are connected respectively to 6 of GAL16V8,5,4,3 pin, one the four negative or door of input is arranged in GAL16V8,6,5,4,3 pin are its inputs, 8 pin are its outputs, 8 pin are connected respectively to 12 pin of 1 pin and 74HC299, shift clock as counting clock among the GAL16V8 and 74HC299,15 pin of 74HC377 are output pin, and be connected respectively to 2 pin and 9 pin of 74HC299 and 26 pin of T6668 of GAL16V8, play reset T6668 and zero clearing GAL16V8,74HC299,8031 15 pin are connected respectively to 37 pin of T668,7 pin of GAL16V8,2 of 74HC299,3 pin, 14 pin (LD signal) were for low when its effect was played record for GAL16V8,8 times 14 pin of every displacement are just exported 1 positive potential pulse during playback, bidirectional interface is the way of output when recording for 74HC299, bidirectional interface is an input mode during playback, 15 pin of GAL16V8 are connected to 8031 13 pin, its effect is that every displacement just produces interrupt requests for 8 times one time, have no progeny in the microcomputer response by PI mouth read-write voice data, 14 pin of GAL16V8 are connected to 1 pin of 74HC299, its effect is whenever to move 8 figure places just the data of PI mouth to be inserted 74HC299,8031 14 pin are connected to 1 pin of 74HC377,16 pin of GAL16V8 are connected to 11 pin of 74HC377, its effect is to expand parallel port, 7 of 74HC299,13,6,14,5,15,4,16 pin be connected respectively to 8031 1,2,3,4,5,6,7,8, pin is used for the data of access 74HC299.

Advantage of the present utility model:

The utility model is realized need not the operator and is got involved, and promptly paging person directly sends into language in paged person's the beep-pager by getting through, and paged person can hear warm real paging person's sound.Paged person (person who want to call) can deposit memorandum information in this machine by sound-recording function simultaneously, then can remind you to emit memorandum information automatically when the prompt date of appointment.

Fig. 1 is the utility model electricity theory diagram.

Fig. 2 is the former figure of the utility model sound-compound-circuit electricity.

Voice paging Adversaria prompting machine mainly is made up of wireless receiving demodulation machine, microcomputer control circuit, sound-compound-circuit three parts, wherein wireless receiving demodulation machine is one one two a frequency conversion superheterodyne receiver, radio frequency signal is sent into band pass filter after the one-level change is put, filtered signal and local oscillator 1 signal carry out the intermediate-freuqncy signal that mixing produces 10.7MHZ, behind bandpass filtering, produce the intermediate-freuqncy signal of 455KHZ with local oscillator 2 signal mixings again again and carry out putting in the secondary amplitude limit after send into frequency discriminator, be admitted to comparator behind the frequency discrimination again and produce data.Also have voltage detecting circuit in the wireless receiving demodulation machine, will produce index signal and send into microcomputer when cell voltage reduces to 1.1V, power-saving control circuit is realized power-save operation under control of microcomputer simultaneously.

It is the Single Chip Microcomputer (SCM) system that core adds circuit compositions such as RAM with 80CL51 that microcomputer control circuit is one, the power-saving control operation cooperates external circuit to finish jointly by microcomputer, clock pulse is when being sent to CPU, also be sent to power-saving control circuit, produce the energising control signal through counting frequency division, timing, twice electrical pulse blanking time is less than the preamble synchronization sign indicating number duration, then enter normal running if detect the preamble synchronization sign indicating number during the energising, otherwise the end "on" position promptly disconnects receiver power supply and self power supply by system controlled by computer.Data processing operation is mainly finished decoding (being the effect and error correction of BCH code), the address code of data and is discerned (whether being this machine address promptly), the storage of data, processing (being that different BB sound is sent in different services) and the playback and the recording of alarm type.

It is the monolithic speech processing circuit of core with T6668 that sound-compound-circuit is one, and it is analyzed combiner circuit, D/A change-over circuit, sequential generation control circuit etc. by microphone amplifying circuit, bandwidth-limited circuit, ADM and forms.Playback is preceding by microcomputer elder generation energized, the speech-sound data sequence of RAM being analyzed in the combiner circuit is delivered to the D/A change-over circuit again, under the cooperation of sequential generation control circuit, convert voice signal to, sneak into the invalid element of voice signal again by the bandwidth-limited circuit elimination, become to grade such as frequency conversion, emit sound by power amplification and loud speaker more at last, signal after voice signal amplifies via the microphone amplifying circuit during recording is sent into ADM analysis combiner circuit and is realized touching number conversion, be quantized into numerical sequence signal through the conversion of D/A change-over circuit, and under control of microcomputer, deposit among the RAM.
