First, the safety shows
1. LCD splicing screen switching power supply
Please use the single-phase three-wire system with a protected area to communicate with the AC 380V switching power supply, and ensure that the system software of all engineering projects applies to the same protected area. Switching power supply without protection zone cannot be used, and the grounding device pin of the power plug cannot be destroyed.
2. Turn off the power
When moving machinery and equipment or other work that must turn off the power, turn off all switching power supplies, including the main power switch, unplug the power cord, etc., to ensure the safety of the machinery and equipment.
3. Cable
Do not place objects on cables such as power plugs, power cords, communication cables, etc., and prevent the cables from being crawled or squeezed to avoid risks such as power failure or short-circuit failure.
4. Splicing screen power cord connection
When plugging or unplugging the power cord from the machine equipment, the machine equipment must be turned off to prevent damage to the machine equipment. The damage caused by plugging and unplugging is not covered by the warranty.
5. Heat exhaust hole
There will be perforations for heat removal on the outer surface of the machinery and equipment, and there is no need to block this perforation to prevent heat accumulation, damage to the machinery and equipment, or risk of fire accidents.
6. Machine and equipment installation
The machinery and equipment should be installed effectively, such as installed in a standardized sound card rack, main cabinet, server cabinet, or placed on a firm and level operating table surface to avoid falling of the machinery and equipment.
7. Natural environment
The natural environment of machinery and equipment should be dust-proof and waterproof, especially to avoid liquid intrusion and splashing into the interior of the machinery and equipment.
8. Overhaul
All maintenance work should be carried out by technical professional maintenance personnel, without learning and training, you do not have to try to repair the machinery and equipment by yourself. In order to avoid the risk of high voltage shock, it is not necessary to open the case privately.

The bandwidth of the image network reaches 500MHZ, the extremely fast response speed, the use of LVDS differential signal transmission technology, strong anti-interference, the system software of the control board has strong adaptability and good compatibility mode, which is the best choice for the central nervous system of large-screen splicing.
3. Monitoring software
The LCD splicing screen video surveillance system software not only shows the best LCD splicing screen for customers, but also develops special mobile phone software for user-friendly LCD splicing screen operation.
According to the RS232 (RJ485) protocol, the LCD splicing screen operation management system software can complete powerful functions such as remote control of the LCD splicing screen display information wall, display information management methods, and video signal management methods. The program is installed on the customer's operating PC, and various management methods are carried out on the splicing screen according to the customer's PC. The operation panel is friendly and visualized, simple and convenient, and it has changed the disadvantages of traditional TV background wall such as complicated actual operation.
4. Server cabinet (sound card rack)
According to the wall display information specifications and appearance specifications, the design plan can be developed according to the installation natural environment and customer regulations in actual application.
5. Various cables
Various cables will be customized according to the total number of on-site installations and length and other data information.
Three, splicing large screen installation guide
1. The total number of large splicing screens of installation staff arriving for qualification review
1. Under the precondition that the new project can be installed, the installation staff will install and adjust on the spot. After arriving on the spot, the first check the splicing large screen model specifications, the unpacking project acceptance, and the total number, quality and documentation of the project acceptance according to the product details. Server cabinet quality, complete sets of installation parts, etc.
2. Determine the installation natural environment
1. According to the installation regulations of the new project, the installation engineer integrates the design drawings to determine whether the splicing large screen placement position of the natural environment on the spot and the natural environment specifications are in compliance with the installation regulations. Determine the following:
①Determine where to place the large splicing screen;
②Accurately measure the length and aspect ratio of the placement part, compare the proportion of the new project drawing, whether it meets the regulations, if there are special circumstances, it must be pointed out to confirm such as: when there is an anti-static floor, make sure that the anti-static floor aspect ratio matches the installation engineering drawing ; When it is wall-mounted installation, it is necessary to determine whether the wall is a solid core wall or can be uniquely fixed; if it is installed on the wall, the opening specifications of the wall should be determined;
③Determine the power supply system conditions (power socket specifications, grounding devices, power supply, commercial insurance, load, etc.) inspection. If the power supply system has not been shown, the customer (on-site staff) should be required to supply the system immediately to ensure that all new projects are installed normally ;
④ Determine whether the video signal input is timely, that is, whether the power cord is routed to the designated location. If it has not been done, the customer (on-site staff) should be required to immediately enter the power cord to ensure the normal installation of the new project;
2. The natural environment of the installation location is considered: sunlight, heat rejection (natural ventilation) standards, robustness, interference signals, bumps, vibrations, children's touch, dense smoke, wind and sand, dampness and cold, vapor, oil stains, top Natural environmental standards such as suspensions or decorations.
3. After-sales service will not be shown for server cabinets and bases that are not manufactured by enterprises or made by directors. If the customer adheres to the regulations, the after-sales service can be presented. However, if the LCD splicing screen is dropped or dropped due to the quality of the server cabinet, base, and hanger, which causes the LCD splicing screen to be damaged, the installation engineer and Skyworth Qunxin will not Take all obligations.
3. Splicing large-screen server cabinet server cabinet (sound card rack) installation
1. Just start the installation after unpacking the wooden shelf, and install the server cabinet (sound card rack) first. When installing, first connect the base from the first group on the left to the right (from right to left), then install the upper group of server cabinets from the first group on the left to the right (from right to left), then install the face frame, and finally Connect the fixed aluminum fittings of the 46-inch screen module, 2 fixed in each row. Install the server cabinet according to the new project engineering drawings. Assemble the components of the server cabinet to make sure it is firm and stable.
If it is a wall-mounted installation, remove the relevant objects at the installation site, clarify the location of the fixed fixing hole, perform clean openings as much as possible, fix the mounting frame and adjust the position and level, carry out on-site removal and cleanliness, and install splicing large Screen.
Unique installation surface installation: The unique installation surface refers to the concrete, hollow brick wall surface, and the pre-installed steel frame structure support frame. The installation surface is paper-faced gypsum board, perforated brick, veneer board, marble slab, glass or suspended in the air For lifting, attaching to the top, embedding on the mounting surface, special support frame, movable support frame, etc., splicing large screens should not be installed immediately on a unique surface.
Note: The actual installation is carried out according to the engineering drawings of the new project. After installation, check the tightness of the installation to ensure the safety and firmness of the installation.
2. Assemble LCD splicing screen module. The LCD splicing screen module is composed of an LCD display, a watch core, and a fixed bracket. The LCD splicing screen module is assembled before the LCD splicing screen module is installed in the server cabinet (sound card rack).
