on september 18, according to the website of the ministry of industry and information technology, in accordance with the overall arrangement of standardization work, the application for the mandatory national standard formulation and revision plan for "vehicle-mounted wireless broadcast reception system" will be made public, and the deadline is october 25, 2024.
the document shows that the technical responsible units of the project are the ministry of industry and information technology of the people's republic of china and the state administration of radio and television; the drafting units are china automotive technology and research center co., ltd., huizhou desay sv automotive electronics co., ltd., shenzhen hangsheng electronics co., ltd., china automotive research and development institute automotive inspection center (tianjin) co., ltd., china automotive research and development institute new energy vehicle inspection center (tianjin) co., ltd., byd co., ltd., great wall motor co., ltd., etc.
the vehicle-mounted wireless broadcast receiving system is an important infrastructure to ensure that the public can quickly and effectively receive authoritative emergency information in an emergency state. on august 14, 2023, the state administration of radio, film and television, the ministry of industry and information technology, and the state administration for market regulation jointly issued the "notice on further strengthening the management of vehicle-mounted audio and video", deploying and promoting the installation of wireless broadcast receiving systems in the automotive field. the wireless broadcast receiving system has unique advantages in proactively releasing sudden natural disasters (such as earthquakes, floods, etc.) and other safety information to drivers and passengers. the coverage radius of fm radio transmitters exceeds 100 kilometers, and the coverage distance of medium-wave radio stations can reach thousands of kilometers. the transmitters are far away from car drivers and passengers, and the possibility of being affected by the same disaster is small. the wireless transmission distance from 2g/3g/4g/5g cellular receiving terminals to base stations is from hundreds of meters to thousands of meters, and the possibility of car drivers and passengers and base stations being affected by disasters at the same time is very high. therefore, when cellular base stations are damaged due to sudden emergencies such as earthquakes, floods, and typhoons, the wireless broadcast receiving system on the vehicle will play a key role. it is of great significance to formulate relevant standards for vehicle-mounted wireless broadcast receiving systems.
in addition, this standard applies to vehicle-mounted wireless broadcast receiving systems. the main technical content includes its test and evaluation system, specifically the technical requirements and test methods for the functions, performance, vehicle-regulatory environment reliability, and electromagnetic compatibility of terminals and antennas.
