4. Regular checking and inspection of consumables.

 

 

 

The projection room is the place where projection equipment is installed. It is necessary to consider the installation of digital film projector and the setting of relevant film stereo equipment. Therefore, the technical requirements of digital projection equipment should be considered in the design, layout, installation, connection and debugging of projection room. The main contents include: projection window, power supply capacity, machine layout, elevation angle, network lines and related interfaces, equipment pipelines, exhaust fan fire fighting facilities and so on.

 

 

 

For the current high-end 4K projection equipment, their voltage requirements are AC 200 V to 240 V, 21.5 A to 18 A, 50/60 Hz, single-phase power supply. Therefore, voltage requirements play an important role in the stability of projection equipment. Therefore, when the engineer is inspecting, it is necessary to test the voltage of the equipment to prevent insufficient or over-voltage supply.

 

 

 

At the same time, the power supply to the computer room should be as independent as possible, and the same power supply should not be used with large air-conditioning system and motor system to prevent interference. When the source is brought to the computer room, it should be installed in an independent distribution box, which is convenient for wiring and is close to the distribution cabinet of the projection equipment. After inspection, Universal International Studios and Zhongying Lushan International Studios meet the voltage requirements.

 

 

 

In addition, it is suggested that the projection equipment should normally be powered by three-phase four-wire system, and equipped with protective ground wire and weak signal ground wire. The supply capacity of the computer room should be sufficient and there should be a margin.

 

 

 

For the projection room, it is always necessary to have all kinds of wires: net wires, wires and so on. In this regard, engineers suggest that the connection between equipment is usually in two ways, pipeline or slot, which can be designed according to the specific situation of the computer room. The advantages of pipeline embedding in the ground are beautiful, concealed and good shielding effect. The cable groove is laid out or under the movable board, which is easy to maintain and repair. Either way, attention should be paid to preventing rats from gnawing on the connection.
