High-bandwidth low-delay vehicle-mounted audio and video transmission system based on 5G communication

Abstract

The invention discloses a 5G communication-based high-bandwidth low-delay vehicle-mounted audio and video transmission system, which comprises a central main control board, a communication board, an MCU exchange board and a video board, and is characterized in that the communication board comprises an embedded development board, and the embedded development board is electrically connected with a first 5G communication module, a second 5G communication module and a Wifi module through a USB connector; the embedded development board is electrically connected with the central main control board, and the central main control board is electrically connected with a plurality of RS232 connectors, a plurality of CAN connectors and an RS485 connector. The system can be connected with a 5G communication network, a hotspot can be transmitted to other equipment for use through the Wifi module, the network can be used anytime and anywhere, videos can be transmitted to background software through the HDMI, a plurality of paths of aviation heads can be accessed to meet the access of different vehicle-mounted modules, various interfaces are arranged in the system, the system can be in butt joint with most vehicle-mounted equipment, and the system is simple in structure and convenient to use. And the operation condition of the vehicle-mounted equipment is uploaded in real time, so that information interaction with an emergency center or a command center is facilitated.

Description

technical field [0001] The invention relates to the technical field of ambulances, in particular to a high-bandwidth and low-latency vehicle-mounted audio and video transmission system based on 5G communication. Background technique [0002] At present, the medical equipment data is reported to the medical center through the phone of the medical staff in the car, and the data transmission cannot achieve continuity and multi-path. The number of supported medical equipment causes a lot of work pressure for the medical staff, and the data of the cameras inside and outside the car is stored first. In the hard disk in the car, it can be retrieved separately when necessary, or periodically copied from the hard disk of the car to the medical center through the medium for data storage, which cannot be observed and commanded in real time; simple treatment of patients in the car requires remote assistance from experts and In the hospital, medical staff conduct simple communication thr...

Problems solved by technology

[0002] At present, the data of medical equipment is reported to the medical center through the telephone of the medical staff in the car. The data transmission cannot achieve continuity and multi-channel. The large number of supported medical equipment has caused a lot of work pressure for the medical staff. The data of the cameras inside and outside the car are stored first. In the hard disk in the car, it can be retrieved separately when necessary, or copied from the hard disk on the car to the medical center for data storage on a regular basis through the media, so real-time observation and command cannot be achieved; simple treatment of patients in the car requires remote assistance from experts and In the hospital, the medical staff conduct simple communication through mobile phone communication or mobile video (unstable and cannot be supported for a long time). The vehicle-mounted OBD system transmits the information of the vehicle to the command center and dispatch in real time through a separate communication system, and monitors the speed of the vehicle. GPS location, driver status, etc., to facilitate vehicle command and dispatch in the background

For the network connection of vehicle-mounted medical equipment on the market, the data of multiple vehicle-mounted medical equipment, the data of cameras inside and outside the vehicle, the data of vehicle-mounted OBD, and the audio and video high-definition communication data of vehicle-mounted 5G smart terminals are connected to emergency centers or command centers through 5G at the same time. There is no communication equipment in the center, which cannot meet the high-bandwidth and low-latency characteristics of emergency vehicles through 5G communication, and achieve the purpose of real-time transmission of multiple data streams
