Main control unit, infrared fileter switch drive circuit are connected successively with the infrared fileter switch, realize the switching to infrared fileter;
Main control unit is connected respectively with stepping motor driving governor, digital signal processing module and network interface respectively, realizes the mutual of the various control signals of video camera.
Working mechanism:
The image sensing plate can be followed the position that image sensing plate linkage is implemented in camera lens primary optical axis direction moving image transmitting sense plate, and the adjusting of the position on the primary optical axis direction of image sensing plate and linkage regulates for stepping motor driving governor control step motor by main control unit; Issuing on the one hand of main control unit regulating command can be undertaken by the manual adjustments instruction of network interface, thereby Jiao's remote manual regulating and controlling behind the realization gunlock, on the other hand, the automatic regulating command that can issue by network interface is also analyzed according to the image definition assessed value that digital signal processing module computed image transducer collects, pass through main control unit, the stepping motor driving governor, stepping motor, the final control chart of image sensing plate linkage carries out position adjustments as sensing plate in the primary optical axis direction, after the position changes, digital signal processing module is responsible for calculating the image definition assessed value, when the adjusting image definition assessed value along with the position reaches peak, think namely that also general image focusing reaches best focus, thereby realize the automatic adjusting that the back is burnt.
The present invention has the following advantages and good effect:
1. significantly improve efficient and the regulating effect of engineering construction period supervision control engineering construction, reduce the workload of high-altitude application, also can guarantee the effect that focal length is adjusted better;
2. in supervision control engineering uses, can realize the dynamic adjustments of the video camera depth of field by back Jiao of long-range adjustment rifle type web camera, thereby can meet the needs of the demand of the outer region-of-interest of the monitoring depth of field;
3. the present invention's high-definition network video monitoring that can be widely used in indoor places such as outdoor location such as road, square, park and bank, office building is used.
