4G Wireless Emergency Cloud Broadcast System & CCTV Linkage for Early Warning


1. System Connection Diagram
The combination of DSPPA 4G wireless emergency cloud broadcast system and CCTV system can be used to effectively prevent drowning accidents and ensure the safety of people’s lives, as well as early prevention and timely processing, focusing on prevention to mainly prevent various potentially harmful behaviors and incidents, and the timeliness of emergency response to take timely and effective measures to the incident. To a certain extent, the loophole of limited manpower has been made up. Cooperated with video surveillance and traditional patrol mechanisms, it can form a joint defense mechanism of “civil defense + physical defense + technical defense”, which can further reduce or even eliminate the occurrence of drowning accidents and other emergency events, and guarantee the safety of people’s lives and property. It can be used in reservoirs, scenic spots, coasts, stations, tunnels, traffic command center and other occasions.



Using high-speed wired and wireless networks, and combined with high-definition cameras and personnel identification technology, the anti-drowning equipment can use the configured column speaker or horn speaker to alert people who are close to dangerous waters to stop wading in time after this conduct is monitored by the camera. At present, the system has been installed and used in many reservoirs, river channels and beach scenic spots. Take the reservoir for example. By setting up fences for the monitoring range of high-definition cameras, when young people are found playing or swimming by the water, the supporting column speaker will automatically or remotely broadcast to alarm and warn the people close to the water to stop wading, effectively preventing the drowning incidents of park visitors and young people around the reservoir. The application of anti-drowning monitoring has won unanimous praise from tourists and surrounding residents.

4. System Functions
1. Integrated broadcast management platform:
DSPPA 4G wireless emergency broadcast system can realize broadcasting and paging to zone, fixed point, fixed area, and all zones. In an emergency, the monitoring command center can combine with the monitoring system to guide the emergency evacuation of the accident site through broadcasting and paging, and deal with the emergency in time, reducing casualties and property losses. It is also possible to monitor traffic congestion to channel traffic in a timely manner, and reduce the number of on-site attendance of road administration or traffic police. The simplified system can not only save investment, but also effectively improve the efficiency of the monitoring center.
2. Combination of wireless broadcasting and CCTV cameras to prevent drowning and emergencies
Using high-speed wired and 4G wireless networks, combined with CCTV, high-definition cameras and personnel identification technology, the system can use the configured column speaker or horn speaker to alert people who are close to dangerous waters to stop wading in time after this conduct is monitored by the camera. Its working principle: When the camera detects that a person is approaching, the camera will send a network linkage trigger signal to the main server, and the host will automatically play the preset or recorded audio, and make announcements to the scene or initiate a paging in the control room through the paging microphone to ask him to leave, in order to deal with emergencies or dangerous situations in a timely manner. Also, it can be used to realize the management of stations, parking lots, construction sites, scenic spots and other areas, which can avoid emergencies, and deal with emergencies in time.
3. Information release, zone management, and timing functions:
It can support timing broadcast for zones, all zones, a single zone, and a single terminal; support real-time shouting function, which can call a single terminal or multiple terminals; support settings for a single zone, multiple zones, and all zones and cycle settings; release text, pictures, audio and video information to the managed visualized extensions.
4. Support secondary development and support docking with third-party systems:
This system platform can be used for docking with third-party equipment on the market, such as VOIP telephone system and SIP protocol intercom system. After the system is set, the other party’s system point terminal can directly broadcast and talk to the system terminal. This system can also provide the SDK secondary development package, which is compatible with multi-party systems (fire system, and monitoring system), and can realize the centralized control and unified scheduling of the integrated management platform.
5. Intelligent and safe broadcasting, controllable and manageable
4G wireless emergency broadcast system can support wired IP and 4G wireless network installation, and can realize the controllable broadcast of all addressable broadcast receiving terminals, and the whole broadcast system has the “controllable and manageable” function. The system has the ability to upgrade and expand in the future, with extremely low cost after operation, and simple and convenient maintenance.

5. Applications

Adopt a completely innovative software platform service model with a new cloud architecture SaaS



Feature:
1. Platform architecture:
The system platform adopts the B/S (Browser/Server, browser/server model) architecture design. This model unifies the client and centralizes the core part of the system function to the server. The browser can interact with the database through the Web Server.
2. Docking advantages:
The system can directly connect with the higher-level intelligent broadcasting platform, accept the control of the higher-level broadcast control center, and forward the emergency broadcast information sent by the national and provincial emergency broadcast systems.
3. Traceable records:
The system platform can record system log occurrence time, operator information, operation content and other information, record system alarm information and its occurrence time, and process alarm information.
4. Equipment network management monitoring:
Equipped with front-end equipment network management, it can remotely monitor and set the working status and working parameters of the equipment, and automatically prompt the failure of the monitored equipment.
5. GIS map supervision:
It has a map interface to manage terminal coordinate information, providing more intuitive online, offline, and terminal statistical information.
6. Security:
The audio signal adopts a digital audio coding format, and the audio signal and control signaling must be authenticated and encrypted for transmission, with anti-attack and anti-tampering mechanisms. The receiving terminal has the advanced anti-interference function, effectively preventing illegal broadcast insertion and intrusion.

Note: (1) A server is provided if you purchase the platform software, which can carry less than 100 terminals. If more than 100 terminals, it is recommended to buy an ordinary server (like DELL R740).
(2) Bandwidth algorithm
Fixed public network IP plus one terminal 0.1M, so 100 terminals corresponds to 10m/bit upstream bandwidth.
2. Rent a cloud server:
The cloud server is open to the DSPPA cloud platform, and customers can rent our servers every year. We charge every year according to the number of terminals. We provide accounts for customers to log in (if you want to rent servers, we recommend renting our own servers).
