Abstract
The utility model relates to a power station workshop video monitoring system comprising a digital camera, a first image processing device, a transmission device, a second image processing device, and a display device. The above design may prevent repeated transmission of images of some objects which are in a power station workshop and which have unchanged physical locations. Only a first-time image acquisition is executed and acquired images are transmitted at one time. Then, in accordance with the difference between image data of a subsequent frame and that of a previous frame, namely, the image data of a different part in cooperation with the image data of the previous frame, current image data is regenerated at the second image processing device in order to be used as the image data of the current frame and is stored to be used as the basis for generating the image data of a next frame. As a result, data transmission quantity can be greatly decreased; dependence on network bandwidth is reduced; and real-time video monitoring can be performed on the scene frames of the power station workshop under a low bandwidth condition.
