LED 디스플레이를 사용해 본 고객은 LED 디스플레이가 맞춤형 제품이라는 것을 알고 있습니다. LED 디스플레이를 구매하는 것은 다른 전자 제품과 다르며 체계적인 솔루션이 필요합니다. 사전 판매에서{0}판매 후{1}}, 설치에서 유지 관리에 이르기까지 기업은 완료해야 합니다. YONGS LED 디스플레이가 오늘 현장 조사 내용에 대해 이야기하러 왔습니다.
① The state of the wall where the display screen is installed, the installation method (inlaid, floor-standing, hanging, wall-mounted, support, pillar) and stress conditions. And according to the specific size of the display screen, confirm whether there are obstacles on the installation site hindering the installation of the display screen. In the case of inlaid installation, whether the reserved installation slot is suitable; if there is a decorative partition on the wall, you must ask the user about the condition of the wall; in the case of column screen installation, you must understand the geological conditions.
② On-site power supply. The capacity of the equipment room or AC transformer, whether the cables need to be rearranged, or whether the wire diameter of the cables already laid out meets the requirements; in the case of single-phase power, whether there is a ground wire; in the case of three-phase power, whether it is three-phase five-wire . If rewiring is required, the length of the power cord in the field needs to be accurately measured.
③ Know the control position of the display screen and whether the communication line is smooth. The length of the communication line required on site, and whether there are other devices with lines that need to be connected to the display control terminal or to understand the switching method of the on-site signal channel; if the user does not understand anything, at least need to understand the user's application requirements, especially the theater class user. If the user has already wired, inquire whether the length and quantity of the wiring are appropriate; the normal synchronization system uses the Cat5e network cable should be less than 120 meters, and the length of the non-category fivee network cable should be lower; if the number is not enough, the corresponding number of network cables must be increased. If it is too long, you must use a suitable optical cable, use multi-mode fiber within 500 meters, and use single-mode fiber for more than 500 meters. There must also be spares in terms of the number of network cables and optical fibers.
④ Tools that need to be carried, such as tape measure or laser ruler. Whether scaffolding is required or user-provided. Whether the computer is provided by the user.
⑤ The external environment of the site. Whether it is installed indoors needs to pay attention to moisture-proof, whether installed outdoors needs to pay attention to the details of waterproof and lightning protection measures; whether the location is close to the sea or a chemical plant, and the degree of air salt, alkali and acid. In addition, outdoor screen users need to observe the viewing distance of the audience, the height of the display screen, and the direction of the sun.
⑥ Try to take pictures of all the situations encountered on the scene with a camera, and take pictures of different angles and details in place.
⑦ Whether the user has special requirements, if there are special requirements, whether it can be realized and the engineering difficulty.
⑧ If the business is responsible for the construction, it is also necessary to go to the local area to understand the specific location of the steel market and building materials market.
