Command center large screen Command center large screen is a display scheme specially used in remote command and dispatch center and other occasions, usually using LED large screen or LCD large screen two products, with some control equipment, to achieve a remote monitoring and command system from the front-end monitoring to the back-end display. This kind of command center screen is widely used in public security, traffic police, production enterprises, urban management and other fields, is an efficient management program. At present, the composition of the large screen scheme of the command center is basically divided into three parts, namely the signal system, the large screen, and the control system.
The signal system mostly refers to the signal source of the front-end, usually contains two categories, one is the monitoring, the other is the data and other information on the computer, such as a city, you can transmit the images collected by the monitoring points dozens of kilometers away to the back end and display them on the large screen, and you can call up the monitoring images at any location. In addition, the signal source can also be the computer of the command center, such as displaying data on the computer and web page information.
Secondly, the core of the large screen display system of the entire command center is the large screen, which is responsible for the display and presentation of the entire content.
LED large screen is often said LED display, is currently used very frequently a large screen display products, it is a commonly used in the command center, the advantage is no seams, high brightness, many types of point spacing specifications, strong selectivity, like P2 or so products are used more in the command center.
LCD large screen is the LCD splicing screen, it is spliced into a large screen through multiple screens, its advantage is high definition, the display monitoring image is very suitable, and a long time is not dazzling, see for a long time has no effect on the eyes, at the same time good stability, can be continuously turned on for a long time, which is suitable for the front-end command center based on monitoring images.
In addition, there is also a command center with a large screen that is DLP, but it is used less now, and the cost performance is average.
Finally, the command center large screen scheme also includes a control system, that is, between the signal source and the large screen, there must be an image processing system, which is responsible for processing and switching the front-end signal source, realizing various display functions, generally using more image processors, matrices, Decoder, etc., the specific use depends on the type of signal source at the front end and the display effect you want to achieve, in addition to some command center large screen systems that require hierarchical management, distributed systems will also be used to realize data sharing and retrieval.
