Description of drawings
For content of the present invention is more likely to be clearly understood, below in conjunction with accompanying drawing, the present invention is further detailed explanation, wherein,
Fig. 1 is the described distribution substation room monitoring system of the embodiment of the present invention 1 structured flowchart;
Fig. 2 is the described distribution substation room monitoring system of the embodiment of the present invention 3 structured flowchart.
Embodiment
Embodiment 1
The described distribution substation room monitoring system of the present embodiment as shown in Figure 1, comprising: digital camera, be used for the video pictures in monitoring distribution station, and have well-determined IP address; The image difference extraction unit is built in described digital camera, receives each two field picture of the video pictures that described camera head monitor arrives, analyzes the otherness of two two field pictures in the setting-up time section, and the difference partial data of the image sets that there are differences of output; Transmission unit is connected with described image difference extraction unit, receives the residing described setting-up time section initial point of image sets that there are differences, the first two field picture of described digital camera output; Receive simultaneously the difference partial data of the difference group image that there are differences of described image difference extraction unit output; And with described the first two field picture and the output of described difference partial data; In the present embodiment, preferred described transmission unit is the GPRS transmission system, and adopts packet-switch technology, follows the IP data network protocol when the transmission of data; Graphics processing unit receives described the first two field picture and described difference partial data that described transmission unit is exported, restores frame by frame video image according to the first two field picture in the setting-up time section and described difference partial data; Monitoring system platform is connected with described graphics processing unit, receives described graphics processing unit and sends each two field picture and show continuously.As preferred embodiment, can select setting-up time is 1 second, and can analyze the otherness of two continuous frames image, and exports the difference partial data of the image sets that there are differences.
Because in the distribution station, the picture that digital camera monitors is almost static, therefore the data volume that the difference between two two field pictures comprises in the setting-up time section is very little, if we were 1 second in the preferred time interval, within the so short time, the difference of its two continuous frames picture can be less.Therefore in data transmission procedure, greatly reduced volume of transmitted data, can transmit how effective information in limited bandwidth.
Embodiment 2
The present embodiment is done following improvement on the basis of embodiment 1, described image difference extraction unit comprises: the picture portion module, be used for each two field picture is obtained M block according to identical partition method, M is natural number, each block is the picture element matrix that pixel forms, be each pixel configuration one parameter according to the brightness of each pixel, the parameter that all pixels in each block are corresponding forms the block counts group; Image comparison module, ((1＜q＜Q) compare one by one by middle corresponding block array with (q-1) two field picture for all the block arrays in 1＜q＜Q) to select the q two field picture; If the m(M of q two field picture〉m〉1) m block array in individual block array and (q-1) two field picture is variant, only exports the m block array of q two field picture; If all block arrays of q two field picture are all identical with all block arrays in (q-1) two field picture, output signal not; Described graphics processing unit is replaced m block array in (q-1) two field picture with the m block array in the q two field picture on all block arrays basis of (q-1) two field picture, obtain all block arrays of q two field picture, reduction q two field picture.
to transmit 24 two field pictures p.s., the size of every two field picture is that 100K is example, the size of the first two field picture is 100K, divide the block of every two field picture according to the resolution of described digital camera, digital camera take resolution as 1024x768 is example, the row of selecting when dividing block and the ratio of row are 1024/768, suppose every two field picture is divided into 8 row 6 row, each two field picture can be divided into 48 blocks, therefore the size of each block is 100K/48, the size of each block only has 2k many, this shows if the difference of two continuous frames image is several blocks, data volume is also very little.Therefore greatly reduce the data volume of the effective information of transmission.
As preferred embodiment, described image comparison module selects (2n+1) the individual block array in q two field picture and (q-1) two field picture to compare, wherein 0≤n≤︱ M/2 ︱; If the q two field picture is identical with (2n+1) individual block array in (q-1) two field picture and (2n+3) individual block array is not identical (2n+2) individual block array is compared, otherwise no longer (2n+2) individual block array is compared.Adopt above-mentioned comparative approach, can reduce greatly operand, be easy to expect, when the some blocks in the two continuous frames image changed, the block around this so greatly possible block also can change; Therefore if the q two field picture is identical with (2n+1) individual block array in (q-1) two field picture and (2n+3) individual block array is not identical (2n+2) individual block array is compared, otherwise no longer (2n+2) individual block array is compared, be that high accuracy rate is arranged, and maximum can reduce by 50% operand.Between the block that compares in the present embodiment, the interval is 1, also can select other interval, it should be noted that the accuracy of the excessive easy impact detection of interval choosing.
