2.2 Power Distribution Renovation
2.2.1 Construction Scope
Since the current power distribution in the conference room cannot meet the power requirements of the LED display system, power needs to be drawn from an adjacent distribution box in the same building. The main construction contents are as follows:
(1). The existing distribution box in the conference room is too small and shall be replaced;
(2). Draw two 3*6 mm² cables from another distribution box in the same building to the conference room distribution box, add circuit breakers, and supply power to the LED large screen;
(3). Relocate the existing two cabinets and UPS power supply to the adjacent control room, and draw cables from the conference room distribution box to the cabinets to supply power to the cabinet equipment and the UPS power supply.
(4). Lighting control renovation: renovate the existing ring-shaped light strip control circuits to enable independent control of the podium ceiling lights and the east/west wall light strips, facilitating lighting control for different meeting scenarios and achieving better video capture and display effects in the venue. Carry out lighting circuit renovation and add new control switches for controlling the podium ceiling lights, while the existing switches control the east/west wall light strips.

2.3 Cabinet Relocation and Audio/Video Network Construction
2.3.1 Requirements Analysis
2.3.1.1 Cabinet Relocation
Convert the current Room 267 into an equipment control room. Relocate the cabinets and backend processing equipment of the video teleconferencing system and daisy-chain conference system to the equipment control room, achieving relative isolation between the conference hall and the control room. Perform maintenance, servicing, and commissioning on existing reusable equipment such as the video teleconferencing system and daisy-chain conference sound reinforcement system to ensure their continued performance. Add an equipment operation console (equipped with control host, mixer, etc.), monitoring speakers, monitors, and other equipment in the equipment control room to facilitate maintenance and operation.
2.3.1.2 Audio/Video Network Construction
On the west side of the rostrum near the large screen area, reserve 2 network ports and 5 HDMI high-definition video teleconferencing interfaces; on the east side of the rostrum in front of the desks, reserve 4 audio channels (2 primary and 2 backup, for dual-line audio capture for rostrum principals), 6 HDMI (4 primary and 2 backup), 2 VGA, and 2 DVI video floor-box interfaces, with the rear ends connected to the equipment cabinet.
On the east wall of the conference room, reserve 2 network ports and 2 HDMI high-definition video teleconferencing interfaces, with the rear ends connected to the equipment cabinet.
Add audio floor-box interfaces at multiple points inside the conference room for daisy-chain microphone deployment.
Modify the existing audio equipment wiring to achieve zone-based control of 2 column speakers and 6 ceiling speakers through the mixer processor.
Replace the two existing speakers on the north and south sides of the west wall with more concealed, better-performing column speakers (embed the column speakers into both sides of the rostrum, wrapped within the columns); replace the 2 speakers on the east and west sides with 6 ceiling speakers (remove the central ceiling light in each small compartment of the conference room ceiling and use those positions for ceiling speaker installation), improving overall sound quality.
Add 2 surveillance cameras, fixedly installed at the top of the east and west walls. The surveillance cameras are normally used for monitoring, and can also be decoded via an added video decoder and connected to the video teleconferencing system for use as conference video.
Add 2 65-inch 4K mobile TVs, using aluminum alloy mobile cart floor TV stands with telescopic adjustable columns.

2.3.2 Construction Plan
2.3.2.1 Sound Reinforcement System Renovation
The conference room dimensions are: 18m×12m (length×width), with a floor-to-ceiling height of 3.3m (from suspended ceiling to floor tiles). The existing sound reinforcement system in the conference room includes 1 mixer, 1 audio processor, 1 daisy-chain conference system (4 chairman units and 26 delegate units), 2 power amplifiers, and 4 sound columns. The conference room dimensions and the existing layout of the 4 sound columns are shown in the figure below:
To improve the overall sound quality, this plan provides 2 sound reinforcement system renovation options.
Replace the two existing speakers on the north and south sides of the west wall with better-performing speakers (embed the speakers on both sides of the podium, enclosed within columns), and change the 2 speakers on the east and west sides to 6 ceiling speakers (remove the central ceiling light in each small compartment of the conference room ceiling and use that location for ceiling speaker installation), to improve the overall sound quality.
The list of newly added equipment is shown in the table below:

2.3.2.2 Cabinet Relocation and Integrated Cabling
For cabinet relocation and integrated cabling, meet the audio/video needs within the conference room, and provide audio/video interfaces, network interfaces, etc. for the conference room.
Using fiber-optic transmission equipment for cabling offers the following advantages:
(1) Using fiber-optic transmission equipment for cabling involves laying optical cable from the conference room to the equipment control room, with fiber-optic transmission equipment at both ends providing video/audio and network interfaces.
(2) Fiber-optic construction involves less workload; the fiber-optic equipment at both ends can be replaced later, making upgrades and expansion convenient;
(3) Fiber-optic transmission uses uncompressed transmission, with no distance limitation, ensuring high-definition, high-quality video transmission.
