Block diagram with reference to shown in Figure 2 describes by the operation principle of this block diagram to timing control circuit.Described timing control circuit is by electronic alarm signal output device 1, optical coupling collection amplification and shaping negative circuit 2, input signal latch cicuit 3, oscillating circuit 4, counting circuit 5, timing finishing control and alert circuit 6, DC power supply circuit 7, control relay circuit 8, timing working indicator light circuit 9 is formed, described electronic alarm signal output device 1 links to each other with shaping negative circuit 2 with optical coupling collection amplification, optical coupling collection amplification links to each other with input signal latch cicuit 3 with shaping negative circuit 2, input signal latch cicuit 3 respectively with oscillating circuit 4, counting circuit 5, control relay circuit 8 links to each other, oscillating circuit 4 respectively with counting circuit 5, timing working indicator light circuit 9 links to each other, counting circuit 5 is with regularly finishing control and alert circuit 6 link to each other, regularly finishing control and alert circuit 6 link to each other with input signal latch cicuit 3, DC power supply circuit 7 respectively with optical coupling collection amplification and shaping negative circuit 2, input signal latch cicuit 3, oscillating circuit 4, counting circuit 5, timing finishing control and alert circuit 6, control relay circuit 8, timing working indicator light circuit 9 links to each other.During work, the quarter-bell signal of electronic alarm signal output device 1 is delivered to optical coupling collection amplification and shaping negative circuit 2, through gathering, amplify, shaping, after anti-phase, signal is delivered to input signal latch cicuit 3, then, latch cicuit 3 output signals drive the relay adhesive to control relay circuit 8, make socket electrifying, regularly begin, simultaneously, latch cicuit 3 output signals make oscillating circuit 4 starting of oscillations to oscillating circuit 4, the square wave of oscillating circuit 4 outputs is transported in the counting circuit 5 to be counted, simultaneously, the signal of oscillating circuit 4 outputs is delivered to timing working indicator light circuit 9, makes its relay indicating light flicker.After counting circuit 5 countings finished, output signal rang its buzzer to timing finishing control and alert circuit 6, and simultaneously, regularly finishing control and alert circuit 6 output signals make the 3 release zero clearings of input signal latch cicuit to input signal latch cicuit 3; Then, input signal latch cicuit 3 issues a signal to control relay circuit 8, and relay is disconnected, and timing working finishes, and simultaneously, input signal latch cicuit 3 issues a signal to counting circuit 5, makes counting circuit 5 release zero clearings.Wherein, DC power supply circuit 7 work that is mainly each parts provides power supply.

Circuit diagram with reference to shown in Figure 3 describes by the course of work of this circuit diagram to timing control circuit.Use the double D trigger of 4013 models in the circuit, first d type flip flop 4013-1 of this double D trigger is as signal latch usefulness, and second d type flip flop 4013-2 is as oscillator usefulness, and on the market, double D trigger has another name called two rising edge principal and subordinate d type flip flops.Counter uses the counter of 4040 models.When starting working, electronics alarm watch output quarter-bell signal, the quarter-bell signal is delivered to a not gate F1 of schmitt inverter 40106 after optocoupler is handled, and to the trigger end CP1 of first d type flip flop 4013-1, signal is latched after shaping is anti-phase; Then, the Q1 end output high level of first d type flip flop makes the relay K adhesive, socket electrifying, regularly begin, the high level of Q1 output is transported to the CP2 end of second d type flip flop 4013-2 of double D trigger 4013 again, makes CP2=1, promptly become high level, so, the oscillator starting of oscillation, can be regulated cycle of oscillation by potentiometer RP.Then, the Q2 end output square wave of second d type flip flop 4013-2 is after 40,106 second not gate F2 of schmitt inverter handle, deliver to the triggering pin cp of counter 4040 again, counter 4040 begins counting, stirs diverter switch SA1 and can beat on the QJ position, also can beat on the QL position, when counter 4040 count down to QJ end output high level, if this moment, switch S A1 also beat on the QJ position, then the high level signal of QJ begins to capacitor C 3 chargings, after about 1 second, the A point is a high level, the G point is a high level also, thereby makes the R1=1 of first d type flip flop 4013-1, i.e. high level, this first trigger is reset, at this moment, relay K disconnects, and regularly finishes; Simultaneously, Ql=1, thus making the CR=1 of counter 4040 zero clearing that resets, double D trigger 4013, counter 4040 all reset after the zero clearing; Then, the delay circuit that two not gates of the F3 of schmitt inverter 40106, F4 and C3, R3 form will be delayed time about 5 seconds, and in these 5 seconds, buzzer B will ring, and remind regularly and finish, and the user can cut off switch S A2 if do not need buzzing.When if switch S A1 beats on the QL position of counter 4040, and counter 4040 is when counting down to QL output high level, and the course of work is also with above-mentioned.When just switch S A1 beat on the QL position, timing range was 80 minutes-16 hours, and when SA1 beat on the QJ position, timing range was 10 minutes-2 hours.In addition, the F5 of schmitt inverter 40106, F6 and diode (LED) are formed the LED flasher circuit, and LED flash of light during timing working is being carried out timing working to remind.

This circuit power adopts transformer step-down and rectification, through arriving three-terminal voltage-stabilizing integrated package 7812 behind the capacitor filtering, exports 12 volts of direct currents again.The relay K normally opened contact is received on the live wire of civil power, and another contact K1-1 is connected on the pin of socket CZ, controls switching on and off of socket power by the folding of relay.Can also be connected in series fuse on the line, to guarantee Electrical Safety.The two ends paralleling switch SA3 of relay K contact closes up switch S A3, promptly becomes common socket, and cut-off switch SA3 promptly becomes regularly socket, easy switching.

RP in the circuit is as regularly regulating usefulness, the length that the size of adjusting RP can be regulated timing.Adopt the electronics alarm watch as the electronic alarm signal output device, make regularly the time started more accurate, and electronics alarm watch itself also can be used as demonstration time usefulness.
