Abstract
The technical problems to be solved in the utility model is that the distance of existing video camera detection is limited, can not reach the object of complete detection fault, for addressing the above problem, a kind of crawl device video line carrier wave control device is provided, it comprises encoder, encoder input is connected with the video camera being arranged on crawl device, and encoder output is connected with remote control terminal by pair cable.The utility model adopts pair cable, utilizes encoder, can make the distance of signal transmission greatly increase.
Description
Technical field
The utility model relates to a kind of crawl device, is specifically related to a kind of crawl device video line carrier wave control device.
Background technology
Originally the video camera on crawl device is connected with remote control terminal by coaxial cable, because coaxial cable wire diameter is thick, in signals transmission loss decay serious, cause the crawl device 300m that can only creep at most, the distance that video camera detects is limited.
Summary of the invention
The technical problems to be solved in the utility model is that the distance of existing video camera detection is limited, can not reach the object of complete detection fault, for addressing the above problem, provides a kind of crawl device video line carrier wave control device.
The purpose of this utility model realizes in the following manner:
Crawl device video line carrier wave control device, it comprises encoder, and encoder input is connected with the video camera being arranged on crawl device, and encoder output is connected with remote control terminal by pair cable.
Described remote control terminal comprises the decoder being connected with encoder, and decoder is connected with controller.
With respect to prior art, the utility model adopts pair cable, utilizes encoder, can make the distance of signal transmission greatly increase.
Accompanying drawing explanation
Fig. 1 is structured flowchart of the present utility model.
Embodiment
As shown in Figure 1, crawl device video line carrier wave control device, it comprises the encoder being connected with crawl device leading portion video camera output, and encoder input is connected with the video camera being arranged on crawl device, and encoder output utilizes PLC technology to be connected with remote control terminal by twisted-pair feeder.Remote control terminal comprises the decoder being connected with encoder, and decoder is connected with controller.
Operation principle of the present utility model is: the video acquisition transmission that PLC technology is applied to endoscope is upper, and adopt twisted-pair feeder to carry out transmission of video, has realized the monitoring camera-shooting within the scope of 1km at least, and detection range is wide.
