Embodiment
With reference to specific embodiment, the utility model is expanded on further, it should be appreciated that these embodiments are merely to illustrate this
Utility model rather than limitation the scope of the utility model.In addition, it is to be understood that reading the content of the utility model instruction
Afterwards, those skilled in the art can make various changes or modifications to the utility model, and these equivalent form of values also fall within application
Appended claims limited range.
Fig. 1 is the utility model structure diagram, and Fig. 2 is the utility model mechanism circuit block diagram, and the structure one kind can language
The cable number plate printing equipment of sound identification, include supporting structure 1, power supply 2, printer 3, singlechip control panel 4, touch display
Screen 5, the lower floor of supporting structure 1 are provided with printer 3, and supporting framework 1 upper strata is provided with singlechip control panel 4, power supply 3, supporting knot
The front side of structure 1 is provided with touch display screen 5, microphone 6.Single-chip microcomputer, voice pretreatment module are provided with singlechip control panel 4, is deposited
Module, acoustic control integrated circuit are stored up, acoustic control integrated circuit is connected with single-chip microcomputer, voice pretreatment module respectively, voice pretreatment mould
Block includes two-stage amplifying circuit, shaping circuit, monostable time delay circuit, light emitting diode, counter, and microphone is put by two-stage
Big circuit is connected with shaping circuit, and shaping circuit is connected with monostable time delay circuit, and monostable time delay circuit passes through light-emitting diodes
Pipe is connected with counter, and touch display screen, printer, memory module, power supply are connected with single-chip microcomputer respectively, are also connected with single-chip microcomputer
There is transmission equipment.
After microphone receives the voice signal of some strength, voice signal is converted to voltage signal, and amplitude very little is amplified
After shaping circuit, monostable time delay circuit is triggered, produces a broad-adjustable pulse signal, drives diode displaying.
Meanwhile this pulse signal is as gating signal, make rolling counters forward, and with numeral method delay time.
Fig. 3 is the utility model two-stage amplification circuit diagram, and two-stage amplifying circuit output voltage and input voltage are anti-phase, and is had
There is the ability of voltage amplification, voltage amplification factor can be adjusted by regulation resistance.Amplify through two-stage, after amplification can be exported
Positive pulse.
Fig. 4 is the utility model shaping circuit figure, and the electric signal that voice signal changes into duration after amplification goes back
It is shorter, is still the pulse signal occurred in a flash, in order that diode can be with stabilized illumination, therefore will be compared with using shaping circuit
Big positive pulse shaping turns into the negative square-wave signal of a standard, and this will use 555 chips to form shaping circuit, as apply close
Special flip-flop circuit.
The pulse signal of input is changed into the negative square-wave pulse signal of standard, next also to enter one through oversampling circuit shaping
Step extends signal time, and this will use monostable circuit, and negative square-wave pulse is converted into positive square-wave pulse, same to time delay
Long steady state time, to make diode stabilized illumination.
Counter is made up of decade counter 74LS90.After clock signal produces, counter should be accessed, due to typically adopting
Core 74LS90 is decade counter, at this moment to carry out counting the conversion of system, centesimal system is converted into by the decimal system,
Chip is cascaded.
Fig. 5 is the utility model acoustic control integrated circuit diagram, and device uses SK-III acoustic control integrated circuits, has four kinds of outputs
State, the pin of output end 11,9,6 are followed successively by high level, and during the 4th kind of state, several output ends are simultaneously low level.When microphone B is received
During to the first time sound, caused pulse voltage is coupled to A1 pin through C1, into its internal amplifier, makes the high electricity of 11 pin output
Flat, the conducting of VT1 positively biaseds, light emitting diode VL1 is bright, bidirectional thyristor VS1 conductings.Because VS1 T1 is extremely directly connected with power supply,
So the voltage highest being added on printer M, printer is in print state.When second of sound, A1 11 pin output is
Low level, VSl cut-offs；9 pin export high level, and the conducting of VT2 positively biaseds, VL2 is bright, VS2 conductings.Because VS2 T1 poles are connected on speed governing
The stage casing of device coil so that printer is in time-out printing state.During the third time sound, A1 9 pin output low level, VS2 is cut
Only；32 pin export high level, and the conducting of VT3 positively biaseds, VL3 is bright, VS3 conductings.Because VS3 T1 poles meet the end of speed change coil, institute
Maximum with reactance, printer is in holding state.When the 4th sound, 11,9,6 pin output low level.So far, VT1~VT3
It is turned off, VS1~VS3 is turned off, and printer is stopped.
