LED sports event screen classification and design requirements
The LED sports event screen has become an essential facility for modern large-scale sports stadiums. It can clearly display the results of the competition before the audience. So what are the common LED sports event screens? What do they need to pay attention to in the design and installation process?
LED sports event screen classification:
The LED sport event screen is generally divided into two parts: dot matrix and timing. The computer network control system is used for data processing to control large-screen display content and provide real-time data for the network system and radio and television systems. The special competition evaluation system is a variety of sports competitions. Get basic rating data infrastructure.
1. Full color LED screen
It is used to play exciting scenes on the arena (including other competition venues) at the competition site, or to replay lively close-up shots in slow motion, etc., or to represent the tournament and a certain event in a three-dimensional animation.
2.LED fence screen
The LED display next to the stadium is not only used to play commercials, but also to playback the wonderful shots on the field, so that every exciting moment can be savored. The LED fence screen is formed by connecting a plurality of individual boxes. For each box weight control, the boxes are connected by snap-type connectors. This design enables manual and quick disassembly and installation, and is easy to maintain. Each box body has a separate support foot behind it. Through the support feet, the angle between the screen body and the ground can be adjusted to ensure the audience's viewing angle.
3. Timing scoring LED screen
It is connected with the timing scoring system of the game, playing the player's performance and related information. From the game's point of view, the timing scoring screen is more important, and some stadiums can not have a large video screen, but they can not be useless. Time scoring screen. The key to the timing and scoring screen is the immediate accuracy and clarity, and on this basis as far as possible to achieve vivid and stronger expression (such as animation, etc.). The scoring screen mainly displays the player's performance, data, or other information in text or text plus graphical animation. Its color can be monochrome, multicolor, or full color.
LED sports event screen design considerations:
1. Security and Reliability
The crowd density of stadiums is large, and the safety performance of the stadium equipment should be placed first. Under normal circumstances, the safety performance of the stadium LED display should meet the 5.4 requirements of the SJ/T11141-2003 standard, and the reliability should meet the requirements of the 5.10 standard. The choice of materials requires the selection of good flame retardant polymer materials (including LED module housings, LED module fillers, PCB boards, power cord jackets, etc.). At the same time, in the power supply design, the stadium LED display must be separate Power supply and meet the requirements of 5.8 in SJ/T11141-2003; the acceptance of cable line construction is required to meet the requirements of GB50168, GB50171; the project quality should meet the requirements of GB50303. In addition, sporting events LED display should have smoke, lightning protection, automatic fire alarm and automatic off screen function, distribution cabinet should have overload protection, leakage protection and step-by-step power-on.
2, the installation location and the number of requirements.
The installation position of the LED display of sports events needs to ensure that more than 95% of the viewers in the fixed seats in the stadium can watch effectively, and have wide viewing distance and wide vision. At the same time, it is required that the display contents of the led display screen allow the athletes, coaches and umpires (except the scoring referees in the diving competition) on the scene to easily and clearly see.
3. Maximum line of sight and character height requirements.
Outdoor sports events LED display brightness requirements 5000cd / square meters or more; dual-color display 4000cd / square meters or more; monochrome 2000cd, square meters or more. Indoor stadium full-color LED display brightness requirements above 1000cd/m2; dual-color LED display above 300cd/m2; monochrome above 120cd/m2. At the same time, in terms of character height requirements, each character of the LED display screen of the swimming pool and diving hall with an independent building structure is at least higher than 0.2 m. The LED display screen of the swimming diving hall integrated with the building structure is at least higher than 0.28 m.
4. Optical performance requirements.
The led display of sporting events requires a wide viewing angle, a large visual distance, a uniform brightness, and an adjustable brightness. When the background illumination is less than 20lx, the contrast of the LED display should be able to reach 100e1. The white field color coordinate is adjustable within the color temperature of 5000K-9500K according to the use environment, according to the CIE1931 colorimetric system, the tolerance is △x∣≦0.030, ∣ △ y ∣≦ 0.030.
5. The display content can be controlled in real time.
It is required to have a rolling timer for real-time display of the game; scrolling of the score of the game can be displayed; the game performance can be displayed by turning pages; the displayed text can be automatically and manually switched. For full-color LED display screens with graphic and video display functions, text and pictures, animations, and live broadcast images should be able to automatically and manually switch between them.
It is also worth noting that the display system of the gymnasium should be able to clearly, timely, and accurately display the information of sports competitions, and show the reality of the competition through multimedia technology, to underline and create a tense and enthusiastic atmosphere. At the same time, it requires a simple, clear, accurate, and convenient man-machine interface, supports a variety of sports competition projects, meets the requirements of various sports competition rules, and is easy to maintain and upgrade.
