【 Weak current College 】 LCD splicing system environment design and requirements

<br> In order to guarantee the LCD splicing system running smoothly, installation site shall meet the following conditions: <br> <br> 1. installation requirements <br> <br> (1) install ground requires flat solid, load-bearing .ability, not deformed. <br> <br> (2) base General direct contact with antistatic floor to ensure long-term load-bearing surface. <br> <br> 2, the operations console (e) the decoration and equipment location .requirements <br> <br> (1) operational control computer's location should be in the mosaic screen opposite, require the operator to facilitate intuitive see mosaic screen operation. If you have a dedicated partition operations control room, the operator control room with large screen .display suite should have the transparent glass, facilitate the operator's view. <br> <br> (2) control of the computer should be as positive in mosaic screen, and the opposite direction and the mosaic screen suitable distance, which makes it easy to .debug, color adjustments, and so on. <br> <br> (3) image controller display should be on a screen next to the wall or rear channel (Cabinet), should be as close as possible to the projection box interface, reducing .the distance RGB alignment. <br> <br> 2. light requirements <br> <br> (1) lighting recommended not concealed downlight, light direction, directly on the screen the screen maintain 3 metres away, so as not to affect the .projection effects. <br> <br> (2) if the control room of the window is large, you should avoid direct sun light, shade, curtain curtains should be dark. <br> <br> 3, alignment and trunking requirements < .br> <br> (1) power cable (RGB, video, networking, serial port, mouse and keyboard extension cable, etc.) should be separated with the strong electric cable alignment, avoid signal interference. If you go Groove, you cannot .share a trunking, share different walk separate trunking alignment. <br> <br> (2) if the floor brick, the composite wood flooring, fixed ground, requests from the signal source (computer RGB signals, video signals) and control the PC .to the graphics controller (or projector) between walking distance trunking, alignment less suitable. <br> <br> (3) if it is antistatic floor, the alignment of the exit should stay cable hole, export. <br> <br> .4. air conditioning requirements <br> <br> (1) mosaic screen behind the maintenance access to good temperature control and thermal measures. If you have central air conditioning into, outlet, if there is no central air conditioning, additional specialized air conditioning ., air conditioning, power sizes depending on the large screen size. <br> <br> (2) maintenance access to temperature and mosaic screen control room, the room temperature should be controlled and remained the same. <br> <br> 5 .. power supply <br> <br> Considering that the system may experience exceptional circumstances occur breakpoints and then power on the storm, add-on unit itself has the power to protect design to ensure that the equipment normal safe operation. <br> < .br> (1) the system of power supply for AC220V ± 5%; for the protection of Earth wire; three eye socket outlet with Mosaic screen number. <br> <br> (2) the concatenation system and image controller and control PC .requirements with phase supply. <br> <br> (3) the power supply voltage to a stable, reliable, and in particular to prevent the power off immediately and, therefore, in principle require the power of the concatenation system must undergo corresponding power .UPS power supply. <br> <br> (4) system device to have a good grounding, grounding resistance "2 Ω to ensure lightning and other special conditions encountered when the equipment is not damaged. <br> <br> 6. system .environment <br> <br> (1) on the back of the concatenation system is maintenance access, maintenance channel width is generally not less than 0.60 m <br> <br> (2) large screen room requirements better temperature and humidity control. .Working environment temperature: 23 ° c ± 5 ° c, relative humidity 20% to 80%. There is air conditioning behind to stitching. <br> <br> (3) mosaic screen front and rear air conditioning temperature and humidity should be transferred .to the same scale, to ensure that the mosaic wall thermal and stitching the flatness of the screen. <br> <br> (4) mosaic screen room requirements to maintain a clean, dust-proof. <br> <br> (5 .) fire sprinkler as far as possible away from the mosaic wall, and you want to use the spray extinguishing agent. <br> <br>.
