Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
This specific embodiment is only to explain of the present utility model, and it is not to limitation of the present utility model, ability
Field technique personnel can make the modification without creative contribution to the present embodiment as needed after this specification is read, but
As long as all being protected in right of the present utility model by Patent Law.
Embodiment one, a kind of disclosed anti-theft alarm system, including control device of wireless 12 and be coupled to controlled in wireless dress
Put 12 and be controlled by the supervising device 1 of the keying of control device of wireless 12.
The preferably distance relay wireless controller, and model GD-RF012A of control device of wireless 12；Controlled in wireless
Device 12 includes remote control and control board, is provided with multicircuit relay in control board, will wherein relay all the way
Normally opened contact the current supply circuit of supervising device 1 is connected to control it to open and close；It can be completed to wireless relay by remote control
The control of device, and then control the keying of supervising device 1.
Supervising device 1 includes electric light, for detecting whether someone is in personnel's inspection that is indoor and exporting personnel's detection signal
Device 11 is surveyed, personnel's detection means 11 is coupled to and detects signal to control the control device 12 that electric light is opened and closed in response to personnel；
When the control supervising device 1 of control device of wireless 12 starts, personnel's detection means 11 detects indoor someone, then control device 12 is controlled
Make electronic startup.
Personnel's detection means 11 is preferably pyroelectric infrared sensor；Pyroelectric infrared sensor includes housing, optics and filtered
Mirror, FET Q4 and pyroelectricity element, housing are provided with through hole, and optical filter is connected in through hole, FET Q4 and heat
The enclosure interior that electric device is located at pyroelectric infrared sensor is released, and outside heat radiation is sensed by optical filter.Optical filter
Main function be only allow a wavelength pass through in 10 μm or so of infrared ray (IR wavelength that human body is sent), and by light,
Sunshine and other radiation are filtered, to suppress extraneous interference.Generally released by two heat in series or in parallel in infrared induction source
Electric device is constituted, and the electrode of the two pyroelectricity elements is on the contrary, ambient background radiation almost has phase to two pyroelectricity elements
Same effect, makes its pyroelectric effect produced cancel out each other, output signal is close to zero.Once someone's intrusion detection region
Interior, human infrared radiation is focused on by partial mirror, and is received by pyroelectricity element, because angle is different, two panels pyroelectricity member
The heat that part is received is different, and pyroelectricity energy is also different, it is impossible to be completely counterbalanced by, and output control is believed after processing circuit processes
Number.Pyroelectric effect is similar with piezo-electric effect, refers to the phenomenon for causing plane of crystal electric charge due to the change of temperature.Pyroelectricity
Infrared sensor is made up of ceramic oxide or piezolectric crystal unit, electrode is made on two surfaces of element, in Sensor monitoring
In the range of temperature when having △ T change, pyroelectric effect can produce electric charge △ Q on two electrodes, i.e., produce between electrodes
A raw faint voltage △ V.Because its output impedance is high, there is a FET Q4 to carry out impedance change in the sensor
Change.Electric charge △ Q produced by pyroelectric effect can be combined and disappeared by the ion in air, i.e., when ambient temperature-stable is constant
When, △ T=O, sensor is without output.Human body or the larger animal of volume have constant body temperature, typically at 37 degree, so meeting
The infrared ray of 10 μm or so of specific wavelength is sent, when human body enters detection zone, because human body temperature and environment temperature have difference, human body
10 μm or so of infrared ray of transmitting gathers infrared induction source (pyroelectricity element) after strengthening by Fresnel lens optical filter
On, infrared induction source will lose charge balance when receiving human infrared radiation, outwards discharge electric charge, and then produce △ T
And by △ T circuit outputs to the periphery, subsequent conditioning circuit handle after testing after with regard to personnel's detection signal can be produced to control control device
12 start.
Control device 12 is relay KM1, and relay KM1 coil is connected to FET Q4 source class, relay KM1
Normally opened contact be connected to electric light L current supply circuit.It is additionally provided with what is opened and closed for controlling it on the current supply circuit of supervising device 1
Controlling switch K1.
Specific work process is as follows：
When resident family is away from home, then supervising device 1 is controlled to start by control device of wireless 12；Pyroelectric infrared sensor is examined
When measuring someone, then FET Q4 is turned on, to cause relay KM1 coil to obtain electric, so as to control electric light L to start, with reality
The situation that now simulation someone turns on light.
Embodiment two, anti-theft alarm system also includes recorder, and recorder starts in response to control device 12；Recorder with
Time-delay mechanism 13 is also coupled between control device 12, time-delay mechanism 13 includes being coupled to control device 12 and filled in response to control
Put 12 be delayed output time delayed signal delay portion 131 and be coupled to delay portion 131 and in response to time delayed signal with control record
The drive division 132 that sound machine is opened and closed.
Delay portion 131 is 555 delay circuits, and the controlled end in delay portion 131 is coupled to relay KM1 normally opened contact to connect
Control signal is received, and exports time delayed signal, the controlled end of 555 delay circuits is power end, therefore relay KM1 normally opened contact connects
It is connected between power supply and 555 chips, when relay KM1 normally opened contact closure, then 555 delay circuit electric energy is provided, when connecing
Behind energization source, because electric capacity C1 is charged, that is, there is electric current and potential difference, so as to ensure the crus secunda and of 555 chips
Six pin are in high level, now the 3rd pin output low level of 555 chips, as electric capacity Cl charges up to charging complete, due to
Do not recharge, therefore in the absence of electric current and current potential, obstructed dc source by electric capacity C1 after electric capacity is fully charged so that
The current potential of the crus secunda of 555 chips and the 6th pin becomes low level, and the electric signal of output end output is overturn, i.e., output end is defeated
The signal gone out is changed into high level from low level, and is always maintained at down.Diode VD is for electric capacity C2 electric discharges after power cut-off
Set.
Drive division 132 includes being coupled to the output end in delay portion 131 and in response to time delayed signal to realize the switch of break-make
Element and in response to the break-make of switch element with control recorder open and close executive component；Switch element is preferably the three of NPN type
Pole pipe Q1, executive component is that inverse parallel has sustained diode 1 on relay KM2, and relay KM2 coil；Triode Q1's
Base stage is connected to the output end in delay portion 131, and triode Q1 colelctor electrode is connected to relay KM2 coil, triode Q1's
Grounded emitter；Relay KM2 normally opened contact is connected to the current supply circuit of recorder.
Specific work process is as follows：
When resident family is away from home, then supervising device 1 is controlled to start by control device of wireless 12；Pyroelectric infrared sensor is examined
When measuring someone, then FET Q4 is turned on, to cause relay KM2 coil to obtain electric, so that control electric light L to start, three poles
Start-up study portion 131 is turned on the time delayed signal for one high level of output that is delayed to triode Q1, triode Q1 simultaneously, relay
KM2 coil obtains electric so that relay KM2 normally opened contact closes to control recorder also to start, and realizes that simulation someone is in.
