Manufacturing process, circuit diagram is designed, circuit diagram is drawn on the wiring board of hole hole with pen, with 30W electric iron selection
Element is welded on the hole hole wiring board circuit diagram of design, and connecting wire uses multiply thin copper wire, and the electronic component being welded is consolidated
Due in box body, power transformer is individually fixed in box body on floor, and loudspeaker are fixed on the left surface of box body, infrared sensor
The inductive head of HC-SR501 modules, switchs toggle switch, and sound pick-up electrostatic microphone is fixed on the panel of box body by certain position
On, the normally opened terminal contacts connection line of output of relay 1 is welded to sound circuit ISD1820 PLAYE pin, as automatic
Control, button and power indicator also are secured on the panel of box body, and button is record button, is connected to circuit I SD1820's
REC pin.
The course of work and component parameters, infrared sensor are the principle developments according to infrared reflection, pass through infrared ray
Principle of reflection, when the hand of human body or certain a part of in infrared spectral range, infrared sensor module HC-SR501 hair of body
Infrared ray that pipe is sent is penetrated because human body hand or body pick up gear and reflex to infrared receiver tube, passes through the micro computer in integrated circuit
Signal after processing is sent out, and being connected to the triode C9013 of amplifier 1 by designed lines carries out Current amplifier, makes output
Intensifying current voltage range expand, the triode C9013 of amplifier 1 output voltage make time base circuit NE555 pass through resistance electricity
The circuit for holding element composition is also referred to as monostable mode of operation（Time base circuit NE555 service behaviours）, make the 3 of time base circuit NE555
Pin exports the high level of 1/2 second, when relay NE555 1/2 second high level pass through and switch 1 toggle switch MTS-102 places opening
Position（Design 1 purpose of switch is in this switch of the fashionable closing of Speech Record, is not influenceed by infrared sensor）, make relay 1
Normally opened terminal contacts are closed 1/2 second, and the sound circuit ISD1820 of its contact portion PLAYE pin are contacted 1/2 second, and suitable human hand is pressed
Once sound circuit ISD1820 PLAYE playback pin buttons, sound circuit ISD1820 just ceaselessly loop play typings
Security warning language（Sound circuit ISD1820 service behaviour 3）, the security warning language signal to noise ratio of sound circuit ISD1820 outputs
It is smaller, pass through amplifier【3】The amplification of TDA2822 power discharging integrated blocks (【3】TDA2822 models are distinguished with bracket purpose, similarly hereinafter), make
Connected loudspeaker export loud and clear security warning language；When people leaves infrared sensor HC-SR501 module induction ranges, Huo Zheyong
The box body of small black covers infrared sensor inductive head, infrared sensor HC-SR501 modules, and no operating voltage exports, connection
Amplifier【2】C9015 is positive-negative-positive, designs its base stage and obtains negative operating voltage, amplifier【2】C9015 work, connection after
Electrical equipment 2 obtains operating voltage, and the sound circuit ISD1820 power supply circuits of its normal-closed end contact portion of the work of relay 2 break
Open, sound circuit ISD1820 cannot get working power, stop playing the security warning language of typing, if material is thus formed people
When body is in infrared sensor module HC-SR501 induction range, relay 1 works, its contact once voice
Circuit I SD1820 PLAYE playback pin, sound circuit ISD1820 output safety caveat always（Certainly security warning language is
The security warning language that staff inputs according to the environmental selection at scene）, when people leaves infrared sensor HC-SR501 module senses
Scope is answered, relay 2 works, and is disconnected sound circuit ISD1820 working power, and sound circuit ISD1820 stops output peace
Full caveat, the input of security warning language, push button and read safe term to living sound pick-up, you can safe term typing language
Sound circuit I SD1820, as long as not secondary typing, the security warning language persistence of former typing（Sound circuit ISD1820 work
Make performance）.
Power work principle：5W output voltage 15v step-down transformers 220V AC voltage by selection, are reduced to 15V
Alternating voltage, pass through 1N4001 diode bridge rectifications, the filtering of 1000 μ F/25V electrochemical capacitors, 7812 three terminal regulator voltage stabilizings
Into 12V DC electricity for amplifier, relay power, then by 7806 three terminal regulator voltage stabilizings be infrared sensor power supply.
Sleepy alarm power line is inserted 220V AC outlets during use, opens switch 2, the red LED of power indicator
Diode is lighted, closing switch 1, and the watchful voice of safety is manually entered by sound pick-up（Press the button pair on Sleepy alarm panel
Firmly the sound pick-up on panel reads safe term, you can safe term typing sound circuit ISD1820）, then switch 1 is opened,
When human body enters outside line sensor assembly HC-SR501 induction ranges（In the range of general 6-7 rice）, infrared sensor module
HC-SR501 exports certain voltage signal, 1 time service of short duration of relay, makes sound circuit ISD1820 loop playbacks always, passes through
Amplifier 3 amplifies sound, and loudspeaker sends loud and clear security warning language, and human body is in infrared ray sensor induction range, language
Speech circuit sends the sound always, until after human body leaves,（Beyond infrared sensor induction range）Be delayed more than a minute, relay
2 work, make phonetical circuit not send source of sound, and loudspeaker does not send the sound, and the prompting of " people is to remind, people walks to stop " being reached with this
Security warning language effect, during demonstration, the small lid of a black can be used, cover infrared sensor（Left equivalent to people infrared
The induction range of sensor）Reminiscences can send security warning language, and the small lid reminiscences for taking down black continues to play safety
Attention device stops playing for a moment.
It is easy that the utility model makes, and the electronic component of utilization is few, simple to operate, easy to use, according to different applications
Occasion, different language is changed at any time, reach the result of broadcast of required different demands, can be applicable to the field that all kinds of danger need to warn
Institute, there is very high the principles of science, there is certain society and promotional value.
