Embodiment
The controller of ringing a bell when the utility model provides the synchronous self-correcting of a kind of multimachine.Below in conjunction with drawings and Examples the utility model is further specified.
Figure 1 shows that system architecture diagram of the present utility model.Among the figure, central control unit (selecting single-chip microcomputer 89C2051 for use) connects ring detecting circuit, DTMF decoding circuit, timing chip circuit, bell switch control module respectively, manually automatic transfer switch/time is regulated button and watchdog circuit, and the input end of ring detecting circuit and DTMF decoding circuit also connects the back and is connected with telephone line interface; The timing chip circuit fills feed circuit with lithium battery and is connected, and the bell switch control module connects the electric bell power output interface.
Manually automatic transfer switch 4 is fixed on the front panel right lower quadrant of instrument, regulates button for the time below manual automatic transfer switch 4, is divided into minute adjusting button 2 and hour adjusting button 3.The front panel upper left quarter is immobile liquid crystal display screen 1 (shown in a front view among Fig. 2) also.
Electric bell power output interface 5 and AC power input interface 6 are fixed on the rear panel right-hand part of instrument, and telephone line interface 7 is fixed on the rear panel lower right corner (shown in b. back view among Fig. 2) of instrument.
In overall circuit schematic diagram of the present utility model shown in Figure 3, select for use single-chip microcomputer 89C2051 as central control unit, watchdog chip MAX813L is arranged, the power end of timing chip PCF8536 fills feed circuit with the lithium battery that is made of diode D201～D203, R201, C201 and is connected, 3 pins of timing chip PCF8536 link to each other with 7 pins of single-chip microcomputer, be responsible for regularly interruption pulse of output, 7 pins of PCF8536 are time data output, are connected with 8 pins of single-chip microcomputer.5,6 pins of timing chip connect with 13,12 pins of single-chip microcomputer respectively, are responsible for the data input and the pulse clock of timing chip respectively and import.When the controller of ringing a bell inserted external power source work, lithium battery began charging, and when ringing a bell the controller outage, timing unit is still kept work, and the assurance temporal information is not lost.The bell switch control module is responsible for carrying out the bell switch control signal that is sent by central control unit, triggers the relay switch of electric bell.The scale-of-two time data and look-at-me, housing face-plate left-hand seat auto-switching push button, minute adjusting button and hour adjusting button low level signal that the back sends that is pressed regularly of binary data, the timing unit of back output takes place in its ringdown, DTMF decoding circuit (HT9032D serves as by decoding chip) of being responsible for accepting the ring detecting unit in the ring incident; Send the control signal and the bell switch control signal of timing unit; Finish the processing of accepting data, ringing a bell is provided with and the current time such as shows at function constantly on liquid crystal display.Mainly be responsible for the ringing a bell timing of controller and interrupt to the timing constantly of ringing a bell.The low level electric bell trigger pip that 9 pins of single-chip microcomputer produce enters the bell switch control module through the BELLON end, by triode Q401, behind the big circuit of Q402 two merits, make diode D402, the D403 conducting, thereby make relay K 401 work, thereby electric bell power output interface BELL and ac power input end connection make and start working with the electric bell that is connected on the power output interface place.When after the duration of setting of ringing a bell, the single-chip microcomputer 9 pins cancellations low level signal of ringing a bell, the BELLON end recovers high level, diode D402, D403 ends, relay K 401 restPoses, and electric bell power output interface BELL and ac power input end disconnect, and inserts electric bell and stops jingle bell immediately.
The ring detecting unit mainly is responsible for the ringdown that is sended over by programme-controlled exchange is detected.When ring takes place, the AC signal of phone is through capacitor C 301, C302 is after straight, become direct current by the bridge type rectification circuit that constitutes by 4 diode D301～D304, be linked into the mu balanced circuit that voltage regulation resistance R303 and stabilivolt D305 constitute, because the voltage magnitude of the ringdown voltage during than the telephone wire on-hook significantly raises, make the voltage and current of diode D306 output terminal respectively through after R305 dividing potential drop and the R304 shunting, reach the state that can make triode Q301 saturated, triode Q301 collector output this moment TRIG end is drawn as electronegative potential, after single-chip microcomputer 6 pins that link to each other with the TRIG end detect this low level, be about to it as the ring detection signal.FSK frequency shift keying signal decoding unit and peripheral circuit thereof constitute, it mainly is responsible for the fsk modulated signal in the telephone wire is decoded, after control single chip computer 6 pins are caught the ring detection signal, the HT9032D decoding chip 5 pins decoding output that is connected with 11 pins is read.
