Description
Technical field
The utility model belongs to microcomputer development field, is related to a kind of infrared warning device.
Background technology
With continuous progressive, the economic continuous development of social science and technology, people's living standard is greatly improved,
The protective awareness of private property is constantly being strengthened, thus new requirement is proposed to anti-theft measure.The present apparatus be exactly in order to
The family electric theft-proof system for meeting the antitheft needs of Modern Residence and researching and developing.
At present, equipping on the market mainly has pressure activated formula burglar alarm, switch electronic burglar alarm and pressure to hide
The various alarms such as light triggering type anti-theft alarming device, but these types of relatively common alarm is all there are some shortcomings, i.e., it is existing
The detection box alarm module of burglar alarm be visible, therefore cause that its concealment is poor, and confidentiality is not strong.
Utility model content
The purpose of this utility model is to provide a kind of infrared warning device；Using infrared ray as the triggering in alarm
Device, improves the concealment and confidentiality of the safety protection devices such as antitheft door.
The purpose of this utility model solves by the following technical programs：
This infrared warning device, including control unit, control unit are connected with reset circuit, and amplification module passes through first
Drive module is connected with control unit；Control unit is connected by amplification module with signal deteching circuit, and control unit passes through
Two drive modules are connected with warning circuit；The signal deteching circuit is infrared probe, and infrared probe is by the infrared of human body radiation
Spectrum is converted to electric signal.
Further, the features of the present invention also resides in：
Wherein signal deteching circuit releases sensor for the heat of double detection meta structures.
The output terminal of wherein signal deteching circuit is provided with voltage stabilizing element.
Clock circuit is wherein also associated with control unit.

Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings：
The utility model provides a kind of infrared warning device, as shown in Figure 1, including control unit 1, control unit 1 is
AT89C51 system module, control unit 1 are connected with reset circuit 2, and reset circuit 2 is manual key reset circuit or powers on
Automatic reset circuit；Control unit 1 is connected by amplification module 6 with signal deteching circuit 5, and signal deteching circuit 5 is infrared spy
Head, specific is that the heat with double detection meta structures releases sensor, its output terminal is provided with voltage stabilizing element；Control unit 1 passes through
One drive module 3 is connected with display module 4；Control unit 1 is also connected by the second drive module 7 with warning circuit 8.
The operation principle of the utility model is：As shown in Fig. 2, the power end of signal deteching circuit 5 is by connecting an electricity
Container and a resistance carry out stable operating voltage, while output terminal increase sets a voltage stabilizing element, exports signal stabilization；When
When detecting human mobile signal, charge signal amplifies by FET, output is changed into high potential after voltage stabilizing, then
Converted by NPN, it is low level to make output terminal；Amplification module 6 uses most basic amplifying circuit；One machine of clock circuit
The device cycle contains 6 period of state, and each period of state is 2 cycles of oscillation, so a machine cycle shares 12 vibrations
In the cycle, if the frequency of oscillation of external quartz oscillator is 12MHZ, a cycle of oscillation is 1/12us, so a machine
The device cycle is 1us；Control unit 1 after work RESET support it is continuous provide 2 machine cycles high level when can be complete
Operated into resetting, such as when the use of crystal oscillator frequency being 12MHz, then the reset signal duration should be not less than 2us.Display module 4
For the RXD pins being connected on outside multiple light emitting diodes in control unit 1, external power supply, after RXD pins set low level, shines
Diode is lighted, and plays display alarm function；The audible alarm that warning circuit 8 is a Speaker, triode and resistance form
Circuit.
