Design of Multi-channel LVDS Switching System Based on CAN
Abstract:Intelligent driving and intelligent network connection technology have become the trend of vehicle development. The data collected by video outside the vehicle, and the data collected by the vehicle monitoring and entertainment system need to be transferred to each computing module. In order to reduce the complexity of automotive electronic design and improve the reusability and robustness of interface, a video input switching control unit, including video data transmission module, CAN controller, power module and so on, will be designed. With the help of this control unit, multichannel input switch of LVDS video can be completed to output video stream on demand. The results show that the designed on-board LVDS video switching module runs well, meets the requirements of scenario use and considers the subsequent mass production.
