Piece machine GND pin and ground connection.
The effect of each group switch being related in the present embodiment is to facilitate user that the various functions of door and window warning device are carried out
Select and arrange, its operational circumstances is with reference to as follows：
Please continue to refer to Fig. 1, the using method of on and off switch 34 is:When up dialling, positioned at the main frame 10 main panel lower left corner
Battery case 30 in battery start to be each circuit in main frame 10 and component is powered, toward when setting aside, cut off described battery pair
Outer supply access.
Light path calibration switch 31 using method be：When up dialling, open light path calibration pattern, and control described light path school
Quasi- display lamp 38 (namely light emitting diode D6) is lighted immediately, if optical receiving circuit (photodiode D2) can be successfully received light
Signal, then control described light path calibration display lamp 38 to extinguish, otherwise light always；Once described light path calibration display lamp extinguishes,
It is believed that light path calibration completes.Toward when setting aside, close light path calibration pattern.Transmitting light path after the completion of light path calibration is then aforementioned
Default transmitting light path, meanwhile, receiving light path is then aforementioned default receiving light path, once door and window is opened, this default transmitting light path
Will be destroyed with default receiving light path, lead to light signal strength that change occurs.
Voice recording switch 32 using method be：When up dialling, open voice recording pattern；User can pass through main frame 10
The Electret condenser microphone 36 (Electret condenser microphone MK1 in corresponding Fig. 7) in the upper left corner carries out the recording of self-defined alarm voice.Toward setting aside
When, then close voice recording pattern.
The using method of speech selection switch 33 is：Toward when setting aside, once there being alert to occur, (becoming occurs in light signal strength
Change), the self-defined of user will be play by the speaker 37 (speaker LS1 in corresponding Fig. 7) positioned at Electret condenser microphone 36 right side
Recording.Conversely, when up dialling, once there being alert to occur, the built-in voice of Play System.
Described single-chip microcomputer master control set communication connects the switch conditions always according to light path calibration switch 31, controls described light path
Calibration display lamp is lighted or is extinguished；Switch conditions with according to described voice recording switch 16, control described audio record circuit
Voice recording；And the selection situation according to described speech selection switch 17, control described audio record circuit to play and correspond to
Alarm voice.
When SR 35 is pressed, it is possible to achieve the reset operation to single-chip microcomputer and audio record circuit.
The workflow of the present embodiment refers to Figure 10.
After start carries out single-chip microcomputer master control set initialization, single-chip microcomputer first carries out the judgement of self-defined sound-recording function, if using
Family starts voice recording function, then single-chip microcomputer master control set activates the voice recording work(of the audio record circuit in alarm device
Energy；After voice recording terminates, system returns again to carry out the judgement of self-defined recording.If user closes self-defined sound-recording function,
Program continues to run with, and single-chip microcomputer will produce square wave voltage signal VS, and drives optical transmission circuit with it.
Optical transmission circuit (light emitting diode D1) starts to launch pulsed optical signals, anti-through orthogonal plane speculum group
Penetrate, according to presetting, optical signal will be returned to entrance aperture after perforation hole outgoing, by optical receiving circuit and light intensity state decision circuit
Be converted to digital voltage signal VR and be input in the corresponding pin of single-chip microcomputer.
Now carry out the judgement of light path calibration pattern, if user starts light path calibration pattern, single-chip microcomputer master control set calls
Drive circuit of indicator in alarm device, if the digital voltage signal VR that detects of single-chip microcomputer impermanent be zero it indicates that lamp drives
The display lamp on galvanic electricity road extinguishes, otherwise, display lamp Chang Liang.Single-chip microcomputer master control set keeps the detection to voltage signal VR and light path
The state of activation of calibration mode, until user closes light path calibration pattern.
If user is not turned on light path calibration pattern, system will go into the state of deploying troops on garrison duty, and single-chip microcomputer master control set is to voltage
Signal VR is detected, if detecting in the high level lasting time of signal VS, signal VR does not keep constant high level, then
Single-chip microcomputer master control set, by the broadcasting calling alarm device to realize alarm voice, now carries out sentencing of self-defined alarm voice again
Disconnected, if user have selected the voice playing self-defined recording, control voice chip is play 5 points of the voice recorded in advance by single-chip microcomputer
Clock, otherwise will play built-in voice 5 minutes, play and enter reset system judgement after terminating；If single-chip microcomputer detects in signal VS
High level lasting time in signal VR keep constant high level be then directly entered reset system judge.
If reset system, return system initializes, repeat the above steps；If not needing reset system, return to certainly
Define the judgement of sound-recording function.
The present embodiment not only has stronger diamagnetism interference performance, also can simulate voice by alarm device and play warning
Voice, builds the sense of reality of someone in house, strengthens the deterrent effect to robber, can preferably ensure the person and the wealth of people
Produce safety.
Embodiment described above only have expressed the several embodiments of the present invention, and its description is more concrete and detailed, but simultaneously
Therefore the restriction to the scope of the claims of the present invention can not be interpreted as.It should be pointed out that for those of ordinary skill in the art
For, without departing from the inventive concept of the premise, some deformation can also be made and improve, these broadly fall into the guarantor of the present invention
Shield scope.Therefore, the protection domain of patent of the present invention should be defined by claims.
