Due to its be conventional technical means of the prior art, those skilled in the art it is to be understood that therefore the present embodiment this is not done it is superfluous
It states.
Specifically, signal amplification circuit generates electric signal, the high input resistance formed by phase inverter and related Resistor-Capacitor Unit
Anti- amplifier is amplified.Its phase inverter U3A is coupled with phase inverter U8A.Signal transformation circuit forms monostable circuit by door 5 and 6
Schmidt circuit is formed by door 7 and 8, the two circuits carry out shaping to circuit jointly.The port marked as 4 of phase inverter U5B
The 1 port connection of NAND gate USA.
Timing circuit is by forming based on 555 timer integrated circuits.Generate constant 0.1HZ square waves output.
It can be used as continual free oscillation clock signal source forever.This signal makes 555 normal timing oblique waves lay under tribute, and 555
The effect of amplifier or Schmitt trigger is only acted as at this time.The third foot of 555 timers in timing circuit passes through a resistance
It is connect afterwards with the third foot of timer chip U2.
The oscillating circuit that CP detection circuits are made of CC7555 generates the CP that clock pulses makees detection circuit.Signal detection electricity
Two JK flip-flops of routing are formed, and such as input password JK2 outputs high level identical with setting code, such as password bad, output
Low level.Countdown warning circuit is made of 74161 counters and a piece of 555.74161 are set as 3 system Counters, when input 3
Circuit is set to 0 during a pulse.High level is exported to 555 by Q2.555 form a multivibrator, output one loudspeaker alarm of termination.
Principle related description：
When the unlocking code for detecting " enabling " meaning of one's words is equal with the code set, circuit output unlocking signal makes lock
It opens.Sound beat is become electric impulse signal to be then amplified, shaping is transformed into the pulse signal of standard.It is the second is set
Code, such as 1101 this unlocking code detection circuit, the circuit is when there is 1101 code in detecting input pulse, i.e.,
Trivial signal is opened in output.The third is warning circuit, when discovery continuously has unlocking signal to arrive three times but does not succeed, alarm electricity
Road enters working condition, and realizes circuit automatic door opening.
Here formant circuit is the sequence detection circuitry for detecting " enabling " code " 1101 ", should be by synchronous sequence electricity
It designs on road.The design of " 1101 " train pulse detection circuit.
The first step：If input signal pulse is 011101100, the relation table between row input and output and state, state diagram
(Fig. 9)：
Second step：It row state table and does and simplifies (S1 with S4 states equivalent)
Compare two states of S1 and S4 it finds that, two states be mutually it is equivalent.Because from the two of S1 states
The switch condition (0/0,1/0) of bar state transduction pathway and the dbjective state (S0, S2) reached and two strips from S4
The switch condition (0/0,1/0) of state transduction pathway and the dbjective state (S0, S2) reached are corresponding consistent.Since S1 and S4
State is equivalent, then S4 can be merged into S1 states in state transition graph goes, and S4 states are then left out, and obtain state transition graph
To simplification.In state converts schematic diagram, original is absorbed from the two bar state transduction pathway of S4, and is directed toward one of S4 from S3
State transduction pathway alters course as S1.1101 train pulse detection circuit state transition graphs after simplification are as shown shown in 10.
Third walks：The excitation at the JK ends of each trigger is listed according to the state table after the characteristic equation and coding of JK flip-flop
Table.
I.e. by increasing the circuit inside machine, the semanteme of enabling is identified, can realize and provide voice certainly
The dynamic function of opening machine door.This function, children are strayed into household electrical appliances has Additional Protection, especially the few people in remote districts
The children looked after.By sound control, the outer action of people is also simplified.The program uses analog circuit device, and overall price is low,
Reliability is high.
The foregoing description of the disclosed embodiments enables professional and technical personnel in the field to realize or use the present invention.
A variety of modifications of these embodiments will be apparent for those skilled in the art, it is as defined herein
General Principle can be realized in other embodiments without departing from the spirit or scope of the present invention.Therefore, it is of the invention
