Problems solved by technology
For high-definition video data with a large amount of data, the transmission speed is affected by the performance of the conductive ring wire, and the transmission speed cannot be increased, and the monitoring image is prone to discontinuity during transmission.
However, when the existing ordinary conductive ring transmits high-definition video data, its cost is low due to its ordinary transmission line, but it affects the speed of data transmission and the distance of transmission.

A data transmission device based on a conducting ring of the present invention is characterized in that the signal input end of the conducting ring is equipped with a serial data conversion module used for converting a video signal from a parallel mode to a serial mode, and the signal output end of the conducting ring is equipped with a parallel data conversion module used for converting the video signal from the serial mode to the parallel mode, and a conversion module control unit used for harmonizing the parallel and serial data conversion modules to work synchronously and harmonically. When the data transmission device based on the conducting ring works, a video digital signal corresponding to the video data is converted into a serial digital signal from a parallel digital signal via the serial data conversion module, then the serial digital signal passes the conducting ring, and then is converted and reduced into the parallel data via the parallel data conversion module. The data is converted and reduced separately via a parallel differential data conversion module and a serial differential data conversion module, so that the data transmission speed is improved, the phenomenon that the transmitted images are not continuous is avoided, and the requirement for the transmission line of the conducting ring is low, when the general conducting ring is limited by the transmission speed and transmission distance at data transmission.
Description
technical field [0001] The invention relates to the technical field of security monitoring data transmission, in particular to a video monitoring data transmission device, video monitoring system and method using a conductive ring. [0002] . Background technique [0003] In the technical field of video monitoring, because video acquisition devices, such as video cameras, are usually monitored dynamically, that is, they rotate. With the development of communication technology, the speed of data transmission is getting faster and faster, and the monitoring images are very clear, complete and continuous transmitted to the remote end. [0004] High-definition conductive rings and ordinary conductive rings are generally used in existing videobubble monitoring. For high-definition conductive rings, high-definition video data can be transmitted at 3G speed, but the cost is relatively high. For ordinary conductive rings, general data transmission requirements can be met. For hig...
