Highway and tunnel directional propaganda system
Product overview
One of the core equipment of the highway and tunnel directional propaganda system is the high-speed directional warning speaker. Highway directional sound can be divided into 140dB, 130dB and 120dB. The speaker, using digital beamforming technology, can achieve directional transmission of sound and avoid interference to other areas. It has the high volume, long-distance transmission ability, and can quickly transmit sound information on the highway, to remind drivers and passengers to pay attention to safety. At the same time, the speaker also supports a variety of communication modes, such as 4G and network cable, which can be fast and stable communication with the digital broadcast control platform, realizing remote control and voice interaction and other functions. High-speed directional warning speaker is an important part of the highway and tunnel directional propaganda system, which plays an important role in improving road safety and management efficiency.
major function
The construction goal of the highway and tunnel directional propaganda system is to improve road safety, driving efficiency, emergency response capacity, management efficiency and service quality, while promoting energy conservation and emission reduction and the construction of smart city.
Improve road safety: through the directional propaganda system, important information can be timely conveyed to drivers and passengers, such as road closure, traffic congestion, emergency rescue, etc., to avoid accidents and improve road safety.
Improve driving efficiency: the system can timely transmit the traffic situation to drivers and passengers in expressways and tunnels, so as to help them make better driving decisions and improve driving efficiency.
Enhance the emergency response ability: in case of emergency or emergency, the system can timely transmit information through the directional propaganda function, guide drivers and passengers to evacuate and take shelter, and improve the emergency response ability.
Enhance road management efficiency: the system can realize remote monitoring and management, without the presence to convey important information, improve management efficiency.
Promote energy conservation and emission reduction: through the directional propaganda system has the function of power amplifier automatic shutdown, and no audio source input can enter the node mode, which is conducive to energy conservation and emission reduction.
Promoting the construction of smart city: The expressway and tunnel directional propaganda system is an important part of the smart city construction, which can provide more intelligent and efficient support for urban traffic management and public services.
System composition
Digital broadcast control platform: the platform is the core of the whole system, responsible for the control and scheduling of each equipment. It can receive and send information through the network or 4G communication mode, and at the same time can realize the real-time monitoring and management of the working state of the equipment.
High-speed directional warning speaker (supporting 4G and network cable) is one of the key equipment of the system, which can accurately transmit the sound to a specific direction through directional sound technology. Speaker speakers usually support 4G and network cable and other communication modes, which can carry out fast and stable communication with the digital broadcast control platform.
Other accessories: These accessories may include power supply, network switches, communication modules, etc., which provide the necessary support and guarantee for the normal operation of the system.
