Background of the project
The Emergency Command Center is an organization that enhances the government's protection of public safety and the handling of public emergencies. Its status is extremely special. In addition to the need to grasp and analyze important information in a timely manner, it is necessary to uniformly receive police and accept major and major public emergencies. It is also necessary to establish an emergency response assurance system, comprehensive coordination and related organization management work.
In order to improve the social early warning system, effectively respond to various risks, safeguard the lives and property of the people, and maintain social stability, it is imperative to establish a highly intelligent emergency command center that integrates communication, command and dispatch.
Application requirements
The provincial emergency command center has a number of functional areas such as the command hall, the duty room, and the conference room. The command hall is divided into an extranet and an intranet. The whole system not only needs to meet the transmission, switching and display of audio and video signals in the area, but also must support internal conferences and remote conferences for work command and dispatch. Therefore, the construction of the project needs to meet the following requirements:
First, support common signal access
The center has a variety of signal sources, including cameras, video terminals, computer signals, cable TV, satellite TV, DVD, etc. The system needs to be compatible with different types of signal access and processing, in the command hall, duty room, meeting room, etc. The terminal output is displayed.
Second, with graphics image stitching processing capabilities
The system needs to have the splicing processing capability of graphic images to meet the functions of large-screen full-screen display, multi-window display, screen cutting and splicing, etc. The staff can grasp the situation of local cities and counties as a whole, and can also monitor the local areas. .
Third, the screen can be previewed back
The system needs to preview all video signals in real time on the PC client and touch screen, and can also view the screen at any time according to the needs.
Fourth, remote signal access management
The signal network of the command hall is divided into an intranet and an extranet, wherein the intranet is used for internal conferences and the extranet is used for remote conferences. The system needs to support the access management of local conference signals, facilitate the internal conferences, and support the access management of remote conference signals. It is convenient to quickly start emergency video conferences, dial the prefecture-level city and county sub-sites, and issue emergency measures.
Five, a variety of control methods flexible operation
The traditional PC operation, with a single staff and fixed seats, can no longer meet the requirements of the command center to respond quickly to emergencies. Therefore, the system is required to provide a variety of control methods to make the control more flexible and convenient.
Project proposals:
CREATOR fast graphic image intelligent digital integrated management platform is a new generation audio and video integration solution developed by CREATOR. The solution can efficiently and uniformly manage and distribute the distributed nodes and display systems of the control command center, and support the seamless connection of various service private networks and various video surveillance systems; with excellent image stitching, window roaming, overlay, window Features such as random scaling or stretching; extremely intelligent in detail design, the preview card PMAX-PR LINK can be used to preview the video before switching, ensuring the accuracy of the switching screen; and the advanced control card PMAX-Con ETN5 provides A variety of types of control interfaces enable control and command reception for a variety of peripherals, downloadable, updated, information query and keyboard operations for controllable programming.
The project includes the construction of multiple areas such as the command hall, the duty room, and the conference room. It uses multiple PRO series hybrid splicing matrices as the core of the system to realize comprehensive management of all audio and video signals in the center. Among them, the inner and outer networks of the command hall are equipped with a 144-channel input and output PRO series matrix, and the duty room and the conference room are equipped with a PRO series matrix of 72 input and output respectively. In terms of management applications, four programmable central control systems are used to achieve centralized control of signals in each functional area and improve system operation efficiency.
Program characteristics
First, multi-format signal hybrid access
It supports mixed access of many different signal types such as VGA, DVI, HDMI, SDI, etc. It is compatible with common various resolutions and can be customized for resolution display. At the same time, the use of optical fiber signal transmission solves the problem of geographical dispersion of functional areas and ensures lossless transmission of signals.
Second, the signal seamlessly switch in real time
The internal hardware design of the device adopts high-definition signal processing mechanism to solve the black field interval problem when single or multiple signals are switched. The switching process has no flicker, no black screen, no jitter, no crack, and meets the requirements of real-time monitoring of signals by users.
Third, large screen splicing
Large-screen splicing processing can achieve image stitching, window roaming, overlay, window size scaling or stretching, etc., while reducing engineering costs, to meet the different needs of business processing.
Fourth, visual operation management
Users can preview all video signals in real time through the PC and touch screen, and quickly and accurately display the correct video content on the big screen, reducing the occurrence of misoperation and improving work efficiency.
5. Scalability, reliability and stability
The core PRO series matrix of the solution adopts modular structure design, supports hot plugging and is scalable, and has redundant power supply design, strong fault tolerance and good recovery capability; the main equipment adopts dual machine or mirror backup. Work mode to ensure stable operation of the system.
