Description

Technical Field

[0001] The invention relates to the technical field of real-time transmission, and in particular to a real-time transmission system for motorcycle competitions. Background Art

[0002] The real-time transmission system for motorcycle racing is a comprehensive solution that integrates multiple technologies, aiming to achieve fast and stable transmission of high-definition video, real-time data and other information during the competition. The system usually includes components such as on-board video acquisition equipment, wireless transmission modules (such as 4G / 5G communication modules), real-time data processing and analysis platforms, and remote monitoring terminals. Through the collaborative work of these components, the system can capture the wonderful moments of the competition in real time, quickly transmit high-definition video streams and key data to the remote monitoring center or audience terminals, and provide all-round real-time information support for event organizers, audiences and the media.

[0003] For example, the Chinese patent with publication number CN213800010U discloses a panoramic camera system for motorcycles, including a hub, a transmission module, a server, a terminal and at least two cameras, wherein the camera is connected to the transmission module through the hub, the signal output end of the transmission module is connected to the signal input end of the server, the server is wirelessly connected to the terminal, one of the cameras is detachably connected to the rear bar light of the motorcycle through a first connection component, and the other camera is detachably connected to the front of the motorcycle through a second connection component. The panoramic camera system uses multiple cameras to collect images, avoiding the problem of blind spots in traditional single panoramic cameras.

[0004] The existing technology has the following problems:

[0005] When FPGA is used for video processing in the real-time transmission system of motorcycle competition, it is often not (used alone) generally configured with a central processing unit (CPU) for task scheduling. For the design of such a chip, the area of ​​the PCB board, the design difficulty, the power consumption will increase, the cost will also increase, and there will be bandwidth limitations between the CPU and the FPGA. A solution based on an IP network is constructed. In this solution, because the IP network bandwidth is too narrow, a video codec is needed to compress the image. After compression, the image will have a delay of several frames. The IP network itself is a packet transmission and switching network, so it will have a large transmission delay, so it is almost not real-time. This unreliable transmission leads to very poor image quality, large and unstable delays, and high costs. Real-time video transmission, as an important component, requires special attention. The use of real-time video transmission technology cannot effectively monitor the safe operation of the competition in real time, and cannot provide early warnings. There are still many deficiencies in real-time monitoring of the situation around the vehicle. Summary of the invention

[0027] The system can be used as a video receiving end or a transmitting end. When the system is used as a receiving end, the transmitting end can be a PC, which receives the video data transmitted from the Ethernet card 6 and outputs it to the display screen through the ultra-high-definition display 5. When the system is used as a transmitting end, the system collects data from the high-definition panoramic camera 1 and sends it to the receiving end via Ethernet.

[0028] like Figure 1 As shown, the ultra-high-definition display 5 is connected to the zynp chip 2 using an LVDS interface.
