The high-speed shouting system integrates a digital broadcasting control platform, front-end digital broadcasting control terminals, high-speed directional speakers, and is a complete solution tailored for the transmission/playback of informationized audio on highways. It integrates intelligence, informatization, and modularity, uses distributed computing architecture, and fully considers the reuse of existing equipment. It is currently the best overall solution for newly built and upgraded highway audio systems.

Parameters of high-speed directional warning speaker and broadcasting control box
One of the core devices of the directional shouting system for highways and tunnels is the high-speed directional warning speaker. The directional sound system on highways can be divided into three categories: ≥ 140dB, ≥ 130dB, and ≥ 120dB
Level of sound pressure. This speaker adopts digital beamforming technology, which can achieve directional propagation of sound and avoid interference to other areas. It has high volume and long-distance transmission
Ability to quickly transmit sound information on highways, reminding drivers and passengers to pay attention to safety. At the same time, the speaker also supports multiple communication methods, such as 4G and Ethernet cables, which can
Fast and stable communication with the digital broadcasting control platform to achieve remote control and voice interaction functions. The high-speed directional warning speaker is a crucial component of the directional shouting system for highways and tunnels
It plays an important role in improving road safety and management efficiency.
