In recent years, led small spacing display screen has developed rapidly, which has the trend of sweeping the whole LED display industry. Led small spacing display screen usually refers to the indoor LED display screen with the LED point spacing below p2.5mm. Today, with the rapid development of information, led small spacing display screen is very popular and shows a rapid development momentum because of its seamless splicing, low brightness and high gray, high refresh rate, ultra-high definition, low energy consumption, long life and many other characteristics that comply with the market demand and the advantages of energy-saving economic development. At present, led small spacing display screen has become an indispensable role in the fields of public security, command and dispatching, safe city and smart city. As the high-end market of the pyramid of the LED display market, the command and dispatching center market has strict requirements on the overall application. The small spacing LED display greatly meets the use needs of the command and dispatching center with its obvious advantages.
Main market distribution of command and dispatching
What is command and dispatching system? Command and dispatching refers to the collection of equipment that comprehensively uses computer, network, communication and automation technologies to transmit command and dispatching instructions and information. It takes the information exchange platform as the core platform to exchange the information of all participating units non blocking and fast point-to-point, point to multipoint and multipoint to multipoint through the information exchange platform, Realize the rapid upload and release of command and dispatching instructions and information. The command and dispatching system can be divided into power command and dispatching system, military command and dispatching system, traffic command and dispatching system, emergency command and dispatching system and production dispatching system of industrial enterprises according to the application occasion. Therefore, the command and dispatching system is widely used in many fields, such as railway, urban rail transit, national defense, electric power, coal, emergency command center and so on.
(1) Field of emergency command center
In the traditional security system, video conference and video surveillance do not interfere with each other and operate at the same time, which means that in order to ensure the normal use of the security system, it is necessary to invest corresponding maintenance costs in the two systems, which virtually increases the use burden. The video command and dispatching system integrates video conference, video monitoring and command and dispatching, and truly achieves “seeing, hearing, calling, accurate information, accurate positioning and fast response”, so as to ensure that the information collection is fast and accurate and the instructions are issued quickly, which greatly improves the response speed and processing efficiency for emergencies. It provides long-distance and high-speed wireless real-time transmission for fire command, rescue, fire and reconnaissance, which greatly improves the speed and efficiency of emergency command and dispatching.
(2) Military and national defense
“If you want to do a good job, you must first benefit yourself.” strengthening the army through science and technology is an important direction of China’s military construction in the new era. The video dispatching system is suitable for the requirements of military combat training and plays a powerful visual real-time interactive command ability in various military training exercises. Through this platform, the command post, training field and even field exercise site can be connected as a whole, combined with the field situation of military exercises, so as to realize the close combination of theoretical training with real troops, real equipment and live ammunition. At the same time, the military modernization management of military airports and military terminals puts forward higher requirements for comprehensive management. The application of command and dispatching can enable relevant leaders and personnel on duty to timely grasp all matters occurring at the airport or terminal site in their own office, so as to provide a strong basis for timely handling relevant situations and decision-making.
(3) Urban Rail Transit
As the most important public transport facility in the city, rail transit has the characteristics of large traffic volume, short departure interval and fast speed. In order to ensure the normal operation and maintenance of rail transit, the role of command and dispatching system is particularly important. Therefore, the application of urban rail transit emergency dispatching command system mainly uses information technology to improve emergencies and improve the efficiency of train dispatching command, emergency disposal and emergency response.
(4) Power field
Sufficient and stable power energy supply directly affects the operation and development of social economy and the well-being of people. It must rely on a mature and stable modern power professional dispatching command and control system, which includes power grid dispatching command center, power production command center, power monitoring center, power trading center, etc., and undertakes the real-time monitoring of power grid data Power production order issuing, power grid operation dispatching, emergency handling and other important functions.
