Abstract

The utility model discloses an intelligent and digital security system. A singlechip acquires a picture video by a camera shooting module. The picture video is coded, and the data volume of a previous frame and the data volume of a next frame are compared; if the data volume is increased, the security system judges that an animated object exists in a video monitoring picture; at the time, the singlechip stores the video monitoring video by a memory card/hard disk and simultaneously sends a reminding short message to the mobile phone of a user by a GSM module so as to realize the purpose of monitoring immediately.

Description

The intelligent digital safety-protection system

Technical field

The utility model relates to a kind of intelligent digital safety-protection system, especially the intelligent digital safety-protection system of discerning about image intelligent.

Background technology

At present the safety-protection system of video monitoring is used for detecting whether mobile object is arranged mainly is to utilize infrared detection method, and this method need install infrared detection equipment additional beyond video recording equipment, increased cost, is difficult for integratedly, and equipment volume is big.The method that is used for video image identification moving object in addition at present mainly is the image difference point-score, and the image difference point-score needs each pixel of two width of cloth images is carried out calculus of differences, and data volume is big, and operand is also big, is unfavorable for realizing on non-PC host computer system.

Increasing image intelligent identification in monitor portion is the trend of safety-protection system development, because can bring more convenience to people like this.Sometimes have no talent as the inside, corridor, this time monitoring camera still constantly store video in hard disk, and the monitor staff also will constantly go to check whether the people is arranged, so not only data volume and operand are very big in Surveillance center, and increases the difficulty of data analysis.

Summary of the invention

The technical problem that the utility model solves is to overcome the above deficiency of prior art, has proposed a kind ofly to judge based on data volume size behind the encoding video pictures whether the intelligent digital of moving object safety-protection system is arranged in the monitor video.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of intelligent digital safety-protection system, comprise photographing module, single-chip microcomputer and memory module, photographing module and single-chip microcomputer are formed image acquisition circuit, memory module and single-chip microcomputer composition diagram are as the video data memory circuit, single-chip microcomputer is by photographing module images acquired video, image/video is encoded, and the data volume size of front and back frame carried out statistical comparison, if the data quantitative change greatly then judge that moving object is arranged in the video monitoring image, this moment, single-chip microcomputer was stored the video monitoring video by storage card/hard disk, send reminding short message to user mobile phone by gsm module simultaneously, thereby reach the immediately monitoring purpose.

This system also comprises synchronous DRAM, and single-chip microcomputer is cushioned the image/video data by synchronous DRAM by behind the photographing module images acquired video.

This system also comprises gsm module, and gsm module and single-chip microcomputer are formed note and transmitted and received circuit.

This system also comprises LCD display, and LCD display and single-chip microcomputer are formed liquid crystal display circuit.

The utility model handles to detect moving object in monitor video whether arranged by the photographing module images acquired to image by single-chip microcomputer, does not need external infrared detection equipment, saves cost, helps integrated design, the product miniaturization.

The utility model only just can store monitor video in the hard disk into when moving object is arranged, can regulate sensitivity voluntarily by the user according to different occasions, send information when monitoring object of which movement at once to the monitor staff, greatly reduced data volume and operand, helped on Single Chip Microcomputer (SCM) system, realizing.

Description of drawings

Fig. 1 is circuit theory diagrams of the present utility model.

Embodiment

The utility model proposes and realized that one judges the new method of moving object based on data volume size behind the encoding video pictures.Be subjected to this feature of motion effects of moving object in the image according to data volume size behind the encoding video pictures, only need that the data volume size of frame before and after the video coding is carried out statistical comparison and can judge whether moving object, the data volume of its image processing is few, operand is few, for the system of resource-constrained is the system of non-PC main frame especially is very important, helps realizing on Single Chip Microcomputer (SCM) system.

For being more readily understood below in conjunction with Fig. 1, the utility model illustrates.

The utility model comprises that shooting, image move detection, video recording and note and handle four parts.

Photographing module 1 is formed image acquisition circuit with single-chip microcomputer 2, GSM (Global System for MobileCommunications) module 5 is formed note with single-chip microcomputer 2 and is transmitted and received circuit, storage card/hard disk 6 and single-chip microcomputer 2 composition diagrams are as the video data memory circuit, with the Single-chip Controlling core, peripheral circuit is furnished with the photographing module circuit, the LCD display circuit, the gsm module circuit, storage card/hard disk circuit, SDRAM (Synchronous Dynamic Random Access Memory synchronous DRAM) buffer circuit, input keyboard, electric power management circuit.

The user can send by mobile phone and note is set to gsm module 5 and pass to single-chip microcomputer 2 set-up functions, as whether sending reminding short message, the number of transmission user mobile phone, the sensitivity of detection etc.

Single-chip microcomputer 2 is by photographing module 1 images acquired, cushion by 4 pairs of image/video data of SDRAM, 2 pairs of image/videos of single-chip microcomputer compress processing, because considered the image motion part in the image compression process, the moving object meeting to encoding video pictures after data volume produce corresponding influence, only need the data volume size of front and back frame is carried out statistical comparison, if the data quantitative change greatly then judge that moving object is arranged in the video monitoring image, this moment, single-chip microcomputer 2 was stored by 6 pairs of video monitoring videos of storage card/hard disk, send reminding short message to user mobile phone by gsm module 5 simultaneously, thereby reach the immediately monitoring purpose.

The user can shoot with video-corder as antitheft reminiscences by the self adaptation that mobile phone is provided with family and be in the state of deploying troops on garrison duty, and when detecting that there are objects moving, reports the information of abnormality by GSM to user mobile phone, records a video simultaneously.

According to actual needs, add that LCD display 3 can make products such as the DPF that has the security protection prompting function, media player, in real time the display video monitoring content.

The beneficial effects of the utility model are as follows:

Directly utilize the intermediate object program of video compression algorithm, can detect whether mobile object is arranged, the data volume that its image is processed is few, and operand is few.

Only just can be video storage in hard disk when object of which movement is arranged, and send at once information to the monitor staff, can regulate voluntarily sensitivity by the user according to different occasions.

Can whether be in the state of deploying troops on garrison duty by the mobile phone setting by the user, as be in the state of deploying troops on garrison duty when detecting that there are objects moving, report the information of abnormality by GSM to user mobile phone.
