Abstract
An antitheft precaution device comprises a single-chip microcomputer, and a data acquisition module, a processing control module, an alarm circuit module, a radio frequency circuit module and a light-emitting display module connected with the single-chip microcomputer. The data acquisition module comprises a pyroelectric infrared sensor, and the processing control module comprises a signal detection circuit and an amplification comparison circuit which are connected; the signal detection circuit is connected with the pyroelectric infrared sensor, and the alarm circuit module comprises an alarm execution circuit, a buzzer and an automatic reset circuit. The pyroelectric infrared sensor can transform an infrared spectrum radiated by a human body into an electric signal, and the electric signal is transmitted to the processing control module to be amplified and compared and then is transmitted to the single-chip microcomputer to be processed and calculated; and then the alarm circuit module is driven to execute an alarm order and send out an alarm sound, and finally, a radio frequency follower sends an alarm signal containing a local address code to a mobile communication system, and after receiving the alarm signal, the mobile communication system immediately transmits the alarm signal to a mobile phone appointed by a user. Therefore, the purpose is achieved that the user can know the alarm instantaneously when being away from home.
Description
Technical field
The utility model relates to the monitoring field, particularly a kind of anti-theft early-warning device.
Background technology
Along with progress and the expanding economy of society, the people's living standard has had large increase.Some valuables of often using in the life such as notebook computer, Mp4, digital camera etc. all become the target of burglary.Therefore, a kind of making is simple, cost is low, easy for installation, and theftproof performance is more stable, and highly sensitive, antijamming capability is stronger, and it is just very necessary that safe and reliable burglar alarm is used for self-protection.The defective that existing traditional alert device is intrinsic and the backwardness of design concept make the traditional alert pattern present many drawbacks, as wrong report fail to report many, warning is single etc.Such alarm can't satisfy the security protection demand that changes day by day and improve at all.Have that a kind of safety and stability is reliable, response in time, realize the zero distance place reports to the police, the safety alarm system to put prevention first, become people's expectation.
The utility model content
For achieving the above object, the utility model provides a kind of anti-theft early-warning device, comprise single-chip microcomputer, and the data acquisition module that is connected with single-chip microcomputer, processing and control module, warning circuit module, radio-frequency (RF) circuit module and luminous display module, described data acquisition module comprises pyroelectric infrared sensor, described processing and control module comprises the signal deteching circuit that is connected and amplifies comparator circuit, signal deteching circuit is connected with pyroelectric infrared sensor, and described warning circuit module comprises warning executive circuit, hummer and automatic reset circuit.
Described processing and control module also comprises a door lock strengthening mechanism, and the control end of door lock strengthening mechanism links to each other with the output terminal of control and treatment circuit.
Described luminous display module is the LED active display.
Wherein the pyroelectric infrared sensor in the data acquisition module can be transformed into electric signal with the infrared spectrum of human body radiation, transferring to processing and control module amplifies, relatively is delivered to single-chip microcomputer and handles computing, drive warning circuit module execution alarm command again and send alarm sound, send the alerting signal that contains this address code by the radio frequency follower to mobile communication system at last, mobile communication system transmits alerting signal after receiving immediately on the mobile phone of user's appointment.
After panalarm is finished corresponding actions, can automatically terminate behind the presignal delay 6s, alert is eliminated the back automatic reset circuit resets system.
Further: described processing and control module also comprises a door lock strengthening mechanism, and the control end of door lock strengthening mechanism links to each other with the output terminal of control and treatment circuit.
Description of drawings
Accompanying drawing is block diagram of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in drawings, a kind of anti-theft early-warning device, comprise single-chip microcomputer, and the data acquisition module that is connected with single-chip microcomputer, processing and control module, warning circuit module, radio-frequency (RF) circuit module and luminous display module, described data acquisition module comprises pyroelectric infrared sensor, described processing and control module comprises the signal deteching circuit that is connected and amplifies comparator circuit, signal deteching circuit is connected with pyroelectric infrared sensor, and described warning circuit module comprises warning executive circuit, hummer and automatic reset circuit.
Described processing and control module also comprises a door lock strengthening mechanism, and the control end of door lock strengthening mechanism links to each other with the output terminal of control and treatment circuit.
Described luminous display module is the LED active display.
Specifically be that the shelter arranges a branch of infrared ray and can detect easily whether the someone comes in and goes out at home, its infrared probe on the monitoring point is transformed into electric signal with the infrared spectrum of human body radiation, transferring to processing and control module amplifies, relatively is delivered to single-chip microcomputer and handles computing, drive warning circuit module execution alarm command again and send alarm sound, send the alerting signal that contains this address code by the radio frequency follower to mobile communication system at last, mobile communication system transmits alerting signal after receiving immediately on the mobile phone of user's appointment.Automatically terminate after presignal delay 6s a period of time, also can remove alerting signal manually, reset circuit resets system after alert is eliminated, or has timer to realize eliminating automatically reporting to the police behind sound and light alarm 6s clock.
