1. Solution Description
Safety is one of the most important topics in people’s daily life; but in recent years, there have been frequent sudden crises in society, such as
Natural Disasters
Hazardous Chemicals
And Major Public Emergencies
But what we can do when such major disasters came to us?
City is an area with dense population. When major disasters arrive, we can only avoid them and evacuate the scene as much as we can. Therefore, our company has designed an emergency broadcasting system according to this situation. It is a broadcasting system combining wireless and network, and it can provide a fast and rapid message transmission channel. The system host can transmit wireless signals to the terminal equipment through a wireless transmitter, or can also transmit directly through the network to the scene, and the disaster news or the possible damage caused by the disaster can be passed to the people in the first place, so that they can know immediately what happened, how to evacuate, avoid risks, and minimize the loss of life and property.

3. Attainable Functions
1. Wireless and Network PA Functions
The system host can support both wireless broadcasting and network broadcasting. You can choose the suitable broadcasting method based on the site construction environment. For example: you can use wireless broadcasting in forests or highways that can not be covered with lines; while you can use network broadcasting in parks or squares that are convenient for installation and wiring to save costs.
2. Background Music (Prompt Tone)
In the host room, the host can be connected to multiple audio sources, such as FM, CD, MP3 and other audio source devices. You can also connect your computer to an audio acquisition card to play the audio on the internet. Besides, you can play different background musics in different areas of the city. For example, you can play background musics in squares, warning voices such as no open flames in forests, and warning signs like “Keep Safe Distance” in highways.
3. Zone Settings
Through the host, you can set different zones in the city broadcasting system for convenient management of public places with dense population such as parks, pedestrian streets, and squares; broadcast to a designated area or multiple areas through remote paging microphone; extend the zones in the system, and choose the wireless broadcasting or network broadcasting based on the needs of the site. It is easy to construct, fast to install, simple to maintain at a later stage, saving costs and eliminating unnecessary wastes.
4. Unattended Operation
The system host has a timing function, which can make a timing program for playing. The system will run according to the program pre-programmed by the broadcast staff under unattended operation. You can play the schedule tone of various sound source types every day manually or regularly. Besides, you can set different programs and different zone volumes at the same time in different timing zones. During the epidemic, you can broadcast the epidemic prevention knowledge and the latest epidemic situation regularly to the residents of the city.
5. Remote Sub-control and Level-to-level Administration
The system has remote control function. The computer in the system network equipped with the control software of this system can operate and modify this system through remote control. The user can make level-to-level administration within his permission according to his actual needs in different places, for more effective real-time broadcast or emergency notification. The system can call the system host for broadcast or temporary emergency broadcast.
6. Emergency Help and Priority Functions
Emergency broadcast is always related to sudden warning information and immediate emergency notification. Under the emergency state, emergency insertion can be realized at all levels of the system according to the principle of emergency broadcasting priority, so that the public can receive those emergency information immediately. There are emergency help buttons on parks, urban roads or highways. You can also use those devices to ask the broadcast center for help in an emergency.
