Seoses kasvava nõudlusega sotsiaalkindlustuse järele suureneb ka nõudlus seireseadmete järele erinevates inseneriprojektides ning vedelkristallekraani ühendussein on väikese energiatarbimisega, kiirguseta ega virvenduseta ning keskkonnasõbralikum, tervislikum ja stabiilsem kui eelmine CRT jälgimine. Seetõttu kasutab seda enamik inseneriettevõtteid.
In view of the details that should be paid attention to during the installation and implementation of the LCD splicing wall project, the following is introduced by the splicing screen manufacturer: the basic composition of the LCD splicing wall
Cabinet LCD splicing unit image control processor control software various wires.
User-self configuration: Video/VGA matrix (distributor) to control the computer (any configuration, the motherboard with RS-232 communication interface)
Süsteemi keskkonna disain ja nõuded vedelkristallide ühendusseinale
Projekti tõrgeteta kulgemise tagamiseks ja süsteemiseadmete normaalse töö kaitsmiseks peab seadmete paigalduskoht vastama järgmistele keskkonnatingimustele:
1. Installation requirements
1) The installation ground is required to be flat and strong, with strong bearing capacity and no deformation.
2) The base is generally in direct contact with the anti-static floor to ensure that the ground does not deform under long-term load-bearing force.
2. Operation console (room) decoration and equipment location requirements
1) The position of the operating control computer should be directly opposite to the splicing screen, and the operator is required to see the operation of the splicing screen conveniently and intuitively. If there is a specially partitioned operation control room, there should be transparent glass between the operation control room and the large-screen display room to facilitate the operator's viewing.
2) The control computer should be located as far as possible in the direction directly opposite to the splicing screen, and at a suitable distance from the splicing screen, so as to facilitate the adjustment of color adjustment and other operations.
3) The image controller should be placed in the channel (in the cabinet) beside or behind the screen wall, and should be as close as possible to the interface of the projection box to reduce the VGA wiring distance.

3, light requirements
1) It is recommended to use a built-in downlight for lighting. The light should not be directly aimed at the direction of the screen. Keep it 3 meters away from the screen to avoid affecting the projection effect.
2) If the windows of the control room are large, avoid direct sunlight and use curtains to block the light. The curtains should be dark.
4, wiring and trunking requirements
1) Weak current cables (VGA cable video network serial port mouse keyboard extension cable, etc.) should be routed separately from strong current cables to avoid signal interference. If you use a cable trough, you cannot share a cable trough, and you should separate the cables into different troughs.
2) Kui tegemist on fikseeritud maandusega, näiteks põrandaplaatide komposiitpuitpõrandaga, peab signaaliallika (arvuti VGA signaali videosignaal) ja juhtarvuti vahel graafikakontrolleri (või projektori liidese) vahel olema juhtmestik. ja mida pikem on juhtmestiku vahemaa Lühike, seda parem.
3) If it is an anti-static floor, a hole should be opened at the cable exit, leaving the cable exit.
5, power supply
Considering that the system may encounter special circumstances, the current impact of breakpoint and re-energization will occur. The LCD splicing unit itself has a power protection design to ensure the normal and safe operation of the equipment.
1) The power supply of the system is AC 220V ±5 percent ; use a three-eye socket with a protective grounding wire; the number of sockets is related to the number of splicing screens.
2) The splicing system, image controller and control PC require power supply in the same phase.
3) The power supply voltage should be stable and reliable, especially to prevent the power on immediately after a power failure. Therefore, in principle, the power supply of the splicing system must be supplied by the corresponding power UPS.
4) The system equipment must be well grounded, and the grounding resistance should be less than 2Ω to ensure that the equipment will not be damaged when encountering special conditions such as lightning strikes.
6, system environment
1) The back of the splicing system is a maintenance channel, and the width of the maintenance channel is generally not less than 060 meters
2) Large-screen rooms require better temperature and humidity control. The working environment temperature is 23 degree ±5 degree , and the relative humidity is 20 percent -80 percent . There must be air conditioning behind the splicing.
3) The temperature and humidity of the air conditioner before and after the splicing screen should be adjusted to the same scale to ensure the heat dissipation of the splicing wall and the flatness of the splicing screen.
4) The splicing screen room must be kept clean and dust-proof.
5) Keep the fire sprinkler as far away as possible from the splicing wall, and spray fire extinguishing agent.
