Abstract

The utility model discloses an automobile anti-theft alarm comprising a human body sensing module, an infrared camera, a cellphone multimedia message sending device, a relay and an integrated circuit IC, wherein the human body sensing module is installed in a steering wheel and connected with a power supply module; the cellphone multimedia message sending device is used for sending an image signal picked up by the infrared camera to an automobile owner cellphone in a multimedia message form; a control coil of the relay is connected with the integrated circuit IC, a contact switch of the relay and the infrared camera are serially connected on the power supply module; and the integrated circuit IC is used for receiving a human body identification signal detected by the human body sensor and electrifying the control coil of the relay after operation. The automobile anti-theft alarm disclosed by the utility model has the beneficial effects of having good sensitivity, avoiding wrong judge caused by external collision or thundering and the like, alarming accurately, effectively playing an alarming role and preventing the automobile stealing behavior.

Description

Car alarm

Technical field

The utility model relates to a kind of warning device, particularly a kind of car alarm.

Background technology

The Along with people's growth in the living standard; Automobile has become requisite walking-replacing tool in the family, however the problem that automobile burglar has become car owners to be concerned about most, and mostly general cab warning is to utilize automobile self loudspeaker to send chimes of doom or utilize loudspeaker as signal source at present; Will send loud and ear-piercing chimes of doom in case there is the people to collide automobile; But there is some open defect in it: the one, and noise emission, especially at night, the Chang Yinwei wrong report; And the resident of motor vehicle environment is much troubled, had a strong impact on resident's physical and mental health; The 2nd, the situation of wrong report happens occasionally, thunderstorm weather particularly, and also to be not easy to judge specifically be the warning which vehicle takes place, and upset the car owner and lived normally; The 3rd, the warning poor effect, joyriding can cut off the loudspeaker power supply rapidly, and vehicle can't be reported to the police.

Summary of the invention

Be technical deficiency more than solving, the utility model provides a kind of warning accurately and timely, the effective car alarm of reporting to the police.

The utility model is realized through following measure:

A kind of car alarm of the utility model, comprise be installed in the bearing circle and all with the supply module bonded assembly: human body induction module; The infrared pick-up head; The cell phone multimedia message sending set, the picture signal that is used for the infrared pick-up head is taken sends to car owner's mobile phone with the mode of multimedia message; Relay, its control coil connects IC, and its contact switch and infrared pick-up head are connected on the supply module; And IC, be used to receive the detected human body identification signal of human inductor, and the control coil of relay got through after the computing.

Above-mentioned human body induction module signal output part and IC are connected with signal processing circuit, and signal processing circuit is used for the human body identification signal is eliminated clutter, increased power, stablizes and amplify.

The beneficial effect of the utility model is:

1. the utility model can be sensed the joyriding at the bearing circle place, and is relatively sensitiveer, avoided because external impact or thunder and wait the erroneous judgement that causes, it is accurate to report to the police; 2. cancel audible alarm, can not send loud ear-piercing chimes of doom, can not influence the life of surrounding resident; 3. in time send to the head portrait photo of car owner joyriding,, be convenient to seek even vehicle also can be stayed evidence steathily;

Description of drawings

Fig. 1 is the structured flowchart of the utility model.

The specific embodiment

Like Fig. 1, shown in 2, a kind of car alarm of the utility model comprises the supply module, human body induction module, infrared pick-up head, cell phone multimedia message sending set, relay, IC and the high voltage package that are installed in the bearing circle.

Supply module adopts the 12V power supply, power supply is provided for whole device.Human body induction module can be sensed near the joyriding bearing circle, and can produce the human body identification signal, and signal is sent to IC through the elimination clutter of signal processing circuit, after increasing power, stable and processing and amplifying.

The control coil of contactless switch connects IC, and its contact switch and infrared pick-up head are connected on the supply module.IC receives the detected human body identification signal of human inductor; And get through the control coil that makes relay after the computing electric, thereby the contact switch of relay is closed, and the infrared pick-up head is got; The infrared pick-up head is taken the image of joyriding; And send the cell phone multimedia message sending set to, and the image that the cell phone multimedia message sending set is taken the infrared pick-up head is forwarded on car owner's mobile phone with the mode of multimedia message, and car owner's very first time just can obtain the image document at scene like this.

The contact switch of the relay recording playback sound chip of can also connecting can increase recording/playing function.

The foregoing description is said to be in order to specify this patent; Though describe through specific term in the literary composition; But can not limit the protection domain of this patent with this; The personage who is familiar with this technical field can change or revise it after the spirit of understanding this patent and principle and reach equivalent purpose, and this equivalence change and modification all should be covered by the claim scope and define in the category.
