Introduction:
To ensure the smooth implementation of the project and to protect the normal operation of the system equipment, the on-site installation of the equipment must meet the following environmental conditions:
1. Installation Requirements
1) The installation ground must be flat, solid, and have strong load-bearing capacity, and it should not easily deform.
2) The cabinet base generally comes into direct contact with the anti-static floor to ensure that the ground can withstand gravity without deformation over the long term.
2. Operation Console (Room) Decoration and Equipment Location Requirements
1) The position of the operation control computer should be directly opposite the splicing screen, allowing the operator to conveniently and intuitively see the operation of the splicing screen. If there is a specially partitioned operation control room, there should be transparent glass between the control room and the large screen display room for the operator’s convenience.
2) The control computer should be as close as possible to the opposite direction of the splicing screen, with an appropriate distance from the splicing screen to facilitate debugging, color adjustments, and other operations.
3) The placement of the image controller should be next to or behind the wall (inside the cabinet), as close as possible to the projection box interface to reduce the RGB wiring distance.
3. Lighting Requirements
1) It is recommended to use recessed downlights for lighting, and the lights should not be directed at the screen; they should be kept at least 3 meters away from the screen to avoid affecting the projection effect.
2) If the control room has large windows, direct sunlight should be avoided, and curtains should be used to block light, with the curtains being dark in color.
4. Wiring and Conduit Requirements
1) Low-voltage cables (RGB, video, network, serial, mouse and keyboard extension cables, etc.) should be routed separately from high-voltage cables to avoid signal interference. If using a conduit, they should not share the same conduit but be routed in different conduits.
2) If the floor is made of tiles or composite wood, there should be a conduit from the signal source (computer RGB signal, video signal) and the control computer to the graphic controller (or projector interface), with the wiring distance kept as short as possible.
3) If using anti-static flooring, there should be openings at the wiring exit for cable outlets.
5. Air Conditioning Requirements
1) The maintenance passage behind the splicing wall must have good temperature control and heat dissipation measures. If using central air conditioning, there should be air supply and return vents; if not, a dedicated air conditioning unit should be added, with the power size depending on the size of the large screen.
2) The temperature in the maintenance passage and the control room for the splicing wall should be controllable and kept at similar levels.
6. Power Supply
Considering that the system may encounter special situations where power interruptions occur and then restart, the splicing unit itself has a power protection design to ensure the normal and safe operation of the equipment.
1) The system power supply is AC 220V ±5%; it should use a three-pronged socket with a protective ground wire; the number of sockets is related to the number of splicing units.
2) The splicing system, image controller, and control PC require the same phase power supply.
3) The power supply voltage should be stable and reliable, especially to prevent immediate power restoration after a power outage; therefore, in principle, the power supply for the splicing system must go through a corresponding power UPS.
4) The system equipment must have good grounding, with a grounding resistance of <2Ω, to ensure that the equipment is not damaged in the event of lightning strikes or other special conditions.
7. System Environment
1) The back of the splicing system is a maintenance passage, which should generally be at least 0.60 meters wide.
2) The large screen room should have good temperature and humidity control. The working environment temperature should be between 0℃-40℃, with relative humidity between 10%-90%. There should be air conditioning behind the splicing wall.
3) The temperature and humidity of the air conditioning in front of and behind the splicing screen should be adjusted to the same level to ensure heat dissipation from the splicing wall and the flatness of the splicing screen.
4) The splicing wall room should be kept clean and dust-free.
5) Fire sprinklers should be kept as far away from the splicing wall as possible, and they should use spray extinguishing agents.
