The utility model is designed a kind of full automatic voice paging operation platform embodiment that is used for the double-tone multi-frequency coding voice paging system, now is described in detail as follows in conjunction with each accompanying drawing:

Fig. 1 is the whole principle of compositionality schematic diagram of full automatic voice paging operation platform.Operating desk comprises bell signal detection device, relay, voice suggestion synthesizer, dual-tone multifrequency digit receiver, signal tone detector, speech circuit, automatic volume regulator, dual-tone multifrequency code sender, simulation switching matrix, two sleeve solid recording modules, launches driving amplifier, is manager (comprising monolithic computer and control signal transducer), nixie display, loud speaker and the keyboard that core constitutes with the single chip microcomputer.

Its operation principle is: under full-automatic paging mode (by the keyboard setting), when the caller puts through this operating desk phone, after ringing detector detects the bell signal 100 that telephone office transmits, to produce signal 101 and send manager, manager makes the relay adhesive with signal 102, and operating desk speech channel and telephone wire are connected, the beginning receiving and transmitting voice, manager starts the voice suggestion synthesizer with signal 103 simultaneously, points out the automatic paging platform to start working to the caller, asks the caller to dial in the paging plane No..

The number that the caller dials on own phone with keyboard is received by the dual-tone multifrequency digit receiver, is converted to signal 105 and send manager temporary.Caller's FD finished dialing, manager become the number received into speech through signal 103 sending voice synthesizers and feed back to the caller school and listen, and the prompting user: then begin to record by " # " key on the phone.If manager learns that by signal 105 caller is by behind " # " key, with providing signal 107 order simulation switching matrixs the recording input 303 or 304 of an idle cover recording module A or B is received the output 201 of automatic volume regulator, and with the speech of caller under signal 108 (recording piece A) or the record of 109 (recording piece B) order recording piece.Behind 10 seconds End of Tapes, manager is transferred to the transmitting terminal 302 of speech circuit to the playback end 203 or 204 of this recording piece with 107 signal command switching matrixs, broadcasts a recording with signal 108 or 109 order recording pieces to the caller again.This recording will send on the telephone wire through speech circuit.

After playback finishes, manager will order the voice prompt synthesizer again to user prompt: if can rerecord by " # " key; As by on-hook behind " * " key, then change this recording over to the wait transmit status.The key code that manager will be dialled in according to the caller that digit receiver is received is handled.If the user by be " * " key, manager will order switching network will just record the recording piece A of sound or B and speech circuit to disconnect, change playbacks to be launched such as backstage over to.To produce signal 112 before the emission sends to launch to radio transition equipment (or the management equipment after a plurality of such operating desk networking) and applies for.When emission or management equipment are sent emission here and allowed signal 111, manager will be transferred to dual-tone multifrequency code sender output 202 input 301 of launching driving amplifier with signal 107 order switching networks earlier.With signal 106 control signaling circuit,, send to transmitter then through the emission driving amplifier with the coded system and the time interval of paging plane No. temporary in the single chip microcomputer according to the speech beeper system regulation.After signaling finished, manager order switching matrix was the playback output 203 or 204 of emission amplifier input 301 reconfigurations to armed recording module, and carried out the emission playback in 10 seconds with corresponding modules A of 108 or 109 signal enablings or B.If it is a plurality of by the person of exhaling that same recording need not be transmitted to, once to launch after playback finishes, this recording module promptly changes idle armed state over to.Single-chip microcomputer will be made corresponding circuit and be recovered to handle.

Under the manual operation state, the paging plane No. of being exhaled is manually squeezed into through keyboard by the operator, then record down caller's speech launch or record down the voice transmission that the operator reports, its process and above-mentioned similar substantially is that every operation changes the on-shift operator into and carries out through keyboard.Single chip microcomputer is with signal 113 loud speaker of ringing, and notification operator is carried out manual operation, and can carry out audible alarm to the mistake in the operation.

Serial output signal 114 is used for carrying out communication with the management computer system that adds with Shen row input signal 115 and is connected.For public network, the paging plane No. that the caller dials in is passed on microsystem by signal 114 and is carried out legal inquiry and emission login.Query Result can be learnt by sealing in signal 115, if be the disabled user, manager will order VODER to use voice notification call person, and withdraw from current operation process, the signal tone detector is used for detecting the user and shifts to an earlier date the busy tone that telephone wire transmits after the on-hook, and corresponding reaction is monitored and made to manager 1 to its testing result 104 where necessary.

Single chip microcomputer is got in touch through signal 116 and control signal transducer.And the 117,118, the 119th, the contact signal of it and keyboard, display.

Fig. 2 is ringing detector and speech circuit schematic diagram.The telephone signal of being come in by local telephone line plug J4 is after L4, C27, C28 filtering high frequency radio disturb, and the bell signal that 25 He Zhi wherein 90 volts can pass through C20, R19.Through D12, D13 rectification, the DC level behind R72, the C24 smothing filtering is enough to make Zener diode D9 conducting, thereby makes photoelectrical coupler U4 (4N35) send ring detection signal/RIND to manager.DC level on the telephone wire is cut off by C20 at ordinary times, and can not make the D9 conducting after the less voice signal rectification of amplitude.

After manager is received ring detection signal/RIND, send the RELY signal and make triode Q2 conducting, relay K 1 adhesive makes the operating desk main body insert local telephone circuit (being equivalent to plain old telephone " off-hook ").The DC feedback that D2-D4 and D6 transmit local telephone always is added to speech circuit U5 (MC34014) by correct polarity.

U5 is typical electronic phone speech circuit.It links to each other with operator's telephone bandset (receiver and microphone) through J6.Be used for realizing the remote call person's of the operating desk and the local telephone other end conversation.Only be with the ordinary telephone set difference: the INHS signal that manager is sent when user recording can surpass remote call person's speech to prevent the slight noises such as breathing sound of operator through the signal of optical coupler U22 (4N35) rupturing operation person microphone; The voice signal of the recording module playback that the simulation switching matrix passes on, perhaps the voice suggestion synthesizer produces synthetic speech VOIA, be added to the TONE end of U5 through isolating transformer T2 after, manager sends/and the MUTE signal can make this voice signal be listened by the caller school that local telephone sends to a distant place through optical coupler U8 (4N35).The voice signal that local telephone is sent here is sent to automatic volume regulator, dual-tone multifrequency digit receiver and signal tone detector through TEL1 and TEL2 end simultaneously.Zener D5, piezo-resistance RV1 are used for lightning protection and limited strong voice signal.Q4 and peripheral circuits make operating desk operating desk under " on-hook " (not having the local telephone network calling) state obtain direct current supply, the operator emission of can recording voluntarily.Realize the operation of operator's transfer.

Main process block diagram when Fig. 9 is the automatic paging operation.Figure 10 is its 1/8 second timing interrupt service subroutine block diagram.The former mainly finishes caller's (user) incoming-call-reply and recording; The latter then when recording request emission is arranged, according to the form described in inventor's patent application (941,014 78.9), transmits catchword coding and recording with voice-frequency signalling to transmitter.For outstanding main points, (for example information shows) particular procedures is not described at large in the block diagram.

Among Fig. 9, under normal paging operation state, main program enters process block 1 after starting, and the initialization setting of complete operation platform is opened and regularly interrupted in 1/8 second.And give and establish working method and be masked as automated manner.

After entering process block 2, whether the requirement of modification mode is arranged with differentiating keyboard.In the process block 3 with correspondingly modification mode sign.Manual operation and two kinds of working methods of automatic operation have many public handling procedures, will rely on this sign that some details are carried out different processing, and these inessential processes are not showed in block diagram.

If the working method sign is not an automated manner, will change the manual operation handling procedure over to by frame 4, be omitted herein.

If be masked as automated manner, will change process block 5 over to, check whether idle recording module is arranged.If record information does not down all send in two recording modules, process block 6 will show " doing " information, be recycled to process block 2 waits, and up to a module being arranged after the free time, program changes frame 7 over to, shows idle information.Process block 8 detects the bell signal whether caller is arranged and arrives.Otherwise be recycled to process block 2.

In case detect bell signal, will change process block 9 over to, closed speech channel relay K 1 inserts local telephone with the operating desk main body.Open overtime monitor timer interruption and busy tone immediately and detect interruption.Subsequently be in caller (user) service process, if the caller surpasses that a specified time is not dialled or input command not, perhaps telephone office provides busy-back signal after the on-hook midway, all will cause service process to finish in advance, overtime monitoring interruption and busy tone detect and interrupt making program jump to process block 26, disconnect relay, recover all initial condition parameters, and get back to process block 2 (overtime monitoring interruption and busy tone detect interrupt routine and be omitted).

Process block 9 also orders the voice suggestion synthesizer to produce synthetic speech, and prompting caller (user) dials in by the person's of exhaling catchword.Process block 10 circulations differentiate whether receive a dialing.(, not giving unnecessary details down as mentioned above) if overstepping the time limit will withdraw from service process.Whenever receive an item, will send display also to be preserved, restart overtime detection by frame 11.Frame 12 judges whether to collect four catchwords.As collecting, frame 13 is closed overtime monitoring, takes out four items of receiving, listens to the user school through the retaking of a year or grade of voice suggestion synthesizer synthetic speech.Simultaneously can pass through serial communication interface (this function can be set it by switch and whether work), to the legitimacy of management computer system queries catchword.As be illegal the catchword, frame 17 will be used the verbal announcement user, close busy tone through frame 25 and detect, and ask user's on-hook again, and frame 26 disconnects relays, recovers parameter, and frame 2 is got back in the service withdrawed from; If legal catchword, frame 15 is reopened overtime monitoring, and begins recording with the voice suggestion user by " # " key.After frame 16 was judged the user and pressed this key, frame 18 was closed overtime monitoring and the recording module of a selected free time its recording input is connected to the output of automatic volume regulator through the simulation switching matrix, starts 10 seconds Recording Process.

Behind the End of Tape, frame 19 user waiting prompt school playback effects disconnect the output of recording piece and automatic volume regulator then.Frame 20 is connected to the input of speech circuit to the playback output of recording pieces through the simulation switching matrix, and playback recording in 10 seconds sends caller (user) school to through telephone wire and listens.

Finish after-frame 21 in playback and reopen overtime monitoring, will record piece playback output and speech circuit disconnect, and record again with voice suggestion user input commands " # ", or order " * " to change emission over to and wait for.

The order circulation that 23 couples of users of frame 22 and frame send detects, and is to get back to frame 18 to record again with decision, still enters frame 24, changes the emission queuing over to.

Frame 24 is closed overtime monitoring, recording module is masked as " expiring ", adds the emission queuing, transfers to 1/8 second timer interrupt routine and launches processing.Frame 25 prompting user on-hooks, and close busy tone and detect., recover all initial condition parameters of automatic working method, be circulated back to process block 2 after frame 26 disconnects relays.

Figure 10 is 1/8 second regularly interrupt service subroutine block diagram.Operating desk when work, in every time interval through 1/8 second, promptly enter this program once.

After entering break in service, process block 01 is at first preserved the main program parameter, and resets 1/8 second next time interrupt timing at interval.After entering process block 02, each interruption will be according to the different shift direction of counting decision of emission progress counter.Be cleared in the initialization procedure of this counter when main program starts.If do not begin to send paging information to transmitter, this process counting remains 0 always.Transmitting in coding and the voice process to transmitter, will add 1 every 1/8 second (promptly through once interrupting) counting, with statistics transmission progress.

If the process counting is 0, the expression transport process does not begin, and break in service will turn to frame 31 to check the piece queuing application emission of not recording.If no, will return by exporting behind the frame 04 recovery main program parameter; If queuing is arranged, frame 32 sends PTT signal application emission to transmitter.Frame 33, will return through frame 04 when not having transmitter of loopback to be ready to signal at transmitter (or a plurality of operating desk arbitration equipment when working simultaneously), and this moment, PTT still kept application status to judge when the next one interrupts whether transmitter is ready to again.

If beaming back a transmitter, external equipment is ready to signal, frame 34 will be selected the recording module that comes head of the queue, and take out the lowest order of the catchword sign indicating number of its correspondence, frame 35 order simulation switching matrixs are connected to the input of emission amplifier to the output of dual-tone multifrequency code sender, send the lowest order of wailing sign indicating number.After frame 03 adds 1 with progress counter, will return via frame 04.

In 8 Interrupt Process processes subsequently, the process counting is the numerical value between the 1-8, and interrupt service routine is only done the process statistics after frame 04 returns by frame 03, does not do other processing.Therefore it is that 9 o'clock ability is closed by frame 41 that last position catchword sign indicating number will continue to send to counting.Promptly describe, continue to send 1 and 1/8 second time by inventor's application for a patent for invention.

When process counting was 9, break in service will change frame 41 over to be carried out, and it will close code sender, and frame 42 takes out higher one that wails sign indicating number, prepares to interrupt next time sending, and the samely then returned after frame 03,04 statistics process.

In the process afterwards, when counting is 10,12,14, break in service will enter frame 51, send last higher one the catchword sign indicating number that interrupts taking-up by code sender.Return through frame 03,04 then, this catchword sign indicating number in Interrupt Process next time since the process counting will be closed by frame 41 by 11,13 or 15.Therefore, wail sign indicating number little-endian is sent, except that lowest order, everybody all continues to send 1/8 second time for other, and the interval between everybody also will be 1/8 second.Promptly meet the requirement of the inventor's application for a patent for invention.

When the process counting is 16, break in service will forward frame 61 to, and it will order the simulation switching matrix that emission amplifier input and code sender are disconnected, and reconfiguration is to the playback output of selected recording piece.Frame 62 will start the playback of recording piece.

When counting was between 17-95, break in service only by returning behind frame 03, the 04 statistics process counting, was not done other processing.Up to the process counting is 96, promptly passes through: (96-16) * 1/8=10 is after second, and emission amplifier and the disconnection of recording piece, frame 72 stops playback to, and the recording piece of having put sound is added " sky " sign by frame 71 order simulation switching networks.Can be by main program once more to its recording.Frame 73 is closed to the application signal PTT of transmitter, and with the progress counter zero clearing, is returned by frame 04 then.
