Abstract

The utility model discloses an automatic alarm based on infrared image recognition and mode match, comprising a digital signal processor, an infrared image sensor, a modem and an Ethernet interface, wherein the digital signal processor is respectively connected with the infrared image sensor, the modem and the Ethernet interface; the digital signal processor is connected with the infrared image sensor by a quick data change bus and infrared feature images of the human, the mouse, the dog, the cat and other animals is present in the digital signal processor and the infrared image sensor uses a CCD or CMOS type infrared array detector to extract the infrared picture and then the digital signal processor differentiates and alarms based on the infrared image recognition and match.

Description

Autoalarm based on infrared image identification and pattern match

Technical field

The utility model relates to the warning device technical field, relates to a kind of autoalarm based on infrared image identification and pattern match in particular.

Background technology

Present Infrared intrusion detector, mainly be based on the infra-red detection technology, in specific zone, detecting infrared ray will report to the police, in complex environment through regular meeting false alarm appears, for example have pet to enter guarded region, for example have mouse to be strayed into guarded region, frequent false alarm has caused alarm to perform practically no function; Traditional infrared alarming can only be reported to the police to personnel's turnover, can not realize warning to specific objective, for example the food warehouse does not need the people is reported to the police, but need be to pet, warnings such as mouse, traditional infra-red alarm is not just realized this warning function to special object, and traditional infra-red alarm do not have the mobile of monitoring objective, can report to the police to static target yet, traditional infra-red alarm does not carry out images match and identification, does not possess intelligent.

The utility model content

In order to solve the problem of above-mentioned existence, the purpose of this utility model is to provide a kind of and can reports to the police to specific target, and has the intelligent autoalarm based on infrared image identification and pattern match.

To achieve these goals, the utility model is by the following technical solutions:

Autoalarm based on infrared image identification and pattern match, be made up of digital signal processor, infrared imaging sensor, modulator-demodular unit and Ethernet interface, described digital signal processor is connected with infrared imaging sensor, modulator-demodular unit and Ethernet interface respectively.

Preferably, described infrared image sensor adopts the above infrared array detector of 2,000,000 pixels.

Preferably, adopt the fast data exchange bus to be connected between described digital signal processor and the infrared image sensor.

Preferably, described modulator-demodular unit is connected with the phone with automatic dialing alarm function.

Preferably, described Ethernet interface is connected with the inside Ethernet of capable of automatic alarm and configuration data.

The utility model is a kind of can the warning to specific objective, and has intelligent alarm.

Description of drawings

Fig. 1 is the utility model connection diagram.

1. digital signal processors among the figure, 2. infrared imaging sensor, 3. modulator-demodular unit, 4. Ethernet interface, 5. fast data exchange bus, 6. phone, 7. inner Ethernet.

Embodiment

Below in conjunction with drawings and the specific embodiments the utility model is made further description explanation.

Embodiment as shown in Figure 1, a kind of autoalarm based on infrared image identification and pattern match, this alarm is made up of digital signal processor 1, infrared imaging sensor 2, modulator-demodular unit 3 and Ethernet interface 4, and wherein digital signal processor 1 is connected with infrared imaging sensor 2, modulator-demodular unit 3 and Ethernet interface 4 respectively.

Digital signal processor 1 is exactly common dsp chip, infrared imaging sensor 2 adopts the above infrared array detector of 2,000,000 pixels, be connected by fast data exchange bus 5 between digital signal processor 1 and the infrared imaging sensor 2, digital signal processor 1 control infrared ray sensor 2 is taken the thermal photograph of surrounding environment with the speed that is not less than three of per seconds, then photo is transferred to digital signal processor 1 by fast data exchange bus 5, there are the mankind in the digital signal processor 1, mouse, dog, the infrared ray characteristic image of cat and some other animals, with artificial example, people's infrared ray characteristic image has following feature: four limbs and head are arranged, certain height is all arranged, after digital signal processor 1 obtains thermal photograph from infrared imaging sensor 2, extract characteristic: head, the height of four limbs, the human infrared ray characteristic image that has with inside mates, if meet, just begin to enter motion detection, because infrared imaging sensor 2 is uninterrupted shootings, when digital signal processor 1 lock-in feature target all from continuous several thermal photograph, and identified human infrared ray characteristic image, and several photo contrasts in front and back, find that this object continues to move, then report to the police at once; Equally, the warning object of setting also can be pets such as cat or dog, in case detect the infrared signature of pet: on all fours, head is littler than human, height and length are all little than the mankind, and just start and report to the police, also be the same to mouse, mainly the report to the police thermal photograph of object of these several classes has obvious difference, can discern by the infrared image of digital signal processor 1 and distinguish warning.

Which kind of specifically to report to the police to target, can be by on inner Ethernet 7, carrying out specific data configuration, inform digital signal processor 1, can be not only convenient but also conversion monitored object in real time efficiently, when the infrared ray characteristic image in thermal photograph that photographs and the digital signal processor 1 after the match is successful, just can transmit the instruction of reporting to the police automatically, also can send warning message to inner Ethernet 7 by Ethernet interface 4 to the phone 6 that is connected with modulator-demodular unit 3.

The utility model is not to rely on infrared ray separately to have and do not have and do simple judgement and warning, but adopt infrared imaging sensor 2, take infrared image, analyze with 1 pair of infrared image of digital signal processor, extract infrared signature image wherein, compare with infrared image in the specific digital signal processor Already in 1 and mate, and judge whether target moves automatically and report to the police, the degree of intelligence height, effectively reduced false alarm, and a tractor serves several purposes, not only can the monitor, can also monitor pet or other specific objectives.

Above-described only is preferred implementation of the present utility model; should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the invention design; can also make some distortion and improvement, these also should be considered as within the protection domain of the present utility model.
