Description

Technical Field

[0001] The utility model relates to the technical field of compression encoders, in particular to an on-vehicle video compression encoder for subway carriages. Background Technique

[0002] On-vehicle video compression technology can minimize the video transmission bit rate without reducing the resolution and frame rate of the original video stream, while effectively saving video storage space. It supports access through the IP network, supports GB-T28029.1-2020 "Rail Transit Equipment Train Communication Network", Onvif 2.0 protocol, and GB28181 "Technical Requirements for Information Transmission, Exchange, and Control of Security Prevention Video Surveillance Networking Systems", supports standard H.264 / 265 encoding, and supports real-time compression of resolutions such as CIF / 360P / 720P / 1080P / 4K. Existing on-vehicle videos need to be stored for 90 days. Only disks can be added to on-vehicle storage, but the on-vehicle space is limited and it is not easy to add. By using video compression technology, the video can be directly compressed by 3 times, and the compressed video can be directly stored on the original on-vehicle storage to achieve a 90-day video storage. Currently, the number of on-vehicle videos that need to be synchronously transmitted to the station is small. To increase the number of video channels for vehicle-to-ground transmission, the vehicle-to-ground communication network needs to be expanded, but it is difficult to replace network equipment. By using video compression technology, the video bit rate of the camera can be directly reduced by 3 times, and 3 times the number of camera video channels can be transmitted based on the existing vehicle-to-ground network. The traditional method of adding disks to solve storage requires a large amount of capital and occupies a large space in the vehicle. By using a video compression device to compress and store the video, there is no need to add disks. The video compression device is only a 1U device and occupies little vehicle space. Updating network communication equipment to solve vehicle-to-ground network communication problems requires a large amount of capital, and a full replacement has a great impact on vehicle operation. By directly using video compression to reduce the transmission network bandwidth, vehicle-to-ground network communication can be ensured.

[0003] As disclosed in the authorized announcement number CN208638508U, a high-definition video compression encoder is disclosed. The present utility model overcomes the problem that the traditional video codec placed in the living room affects the beauty of the living room in the prior art. The present utility model includes a housing of the encoder. A plurality of multimedia interfaces are provided on the side of the housing. The multimedia interfaces are connected to a video compression and encoding module inside the housing. The video compression and encoding module is also connected to a storage module and an FMC interface module. The multimedia interfaces are also connected to the FMC interface module. The FMC interface module is connected to an FPGA. An electronic clock is provided on the surface of the housing. A main control chip is provided inside the housing. The video compression and encoding module and the electronic clock are respectively connected to the main control chip. The present utility model has the advantages of beautiful appearance, simple structure, strong practicability and convenient use. However, during its use, its volume is too large and it is inconvenient to use in a vehicle. Therefore, we propose a vehicle-mounted video compression encoder for subway carriages to solve the problem that the traditional device has too large a volume and is inconvenient to use in a vehicle.
