Emergency Command System Solution

Industry background


The frequent occurrence of natural disaster, terrorist attack and public security incidents in recent years needs the relevant departments making the rapid and correct decisions or disposals. Traditional emergency scheduling is limited by the network and focuses on listening and speaking in short distance. With the rapid development and mature deployment of 3G/4G network, the new generation emergency command communication requires the combination of video and audio.

Adopting digital voice communication, high compression video coding and 3G/4G network transmission control, deploying emergency command terminal in the front end and platform in the command center, the solution realizes the unified coordination and command of all departments and personnel.

Device access

Accessed devices include: emergency suitcase device, Android individual emergency command terminal, emergency MPU, mobile DVR, and the relevant accessories. Upload the video to the network, and report the situation to the command center.


Bearer network

Bearer network is divided into two parts: operator’s network and private network.


Service management platform

The platform is responsible for data receiving and distribution, system management and decision making, user application, scheduling policy establishment, data storage, etc. According to the independent and organic unity principle, it is a full-featured excellent-performance service management platform composed by central management service, stream distribution service, user access service, device access service, storage service, location service, database service, etc.


User application

User application layer includes PC client application, mobile phone client application, dispatching console, large screen display. The specific functions and demands are reflected in user application layer.
