On September 28, 2021, the Sichuan Cultural and Tourism Development Conference (hereinafter referred to as the "Sichuan Cultural Tourism Conference") will be held in Jiuzhaigou County, Aba Prefecture. This conference is the first time that Jiuzhaigou is fully open to tourists after more than four years of reconstruction.

At the same time, in addition to the attractions, it is even more noticeable that the conference introduced a variety of contemporary high-tech equipment. Among them is the first challenge in the country for outdoor fixed mechanical lifting + foldable screens.

The large LED screen stands at the entrance of the scenic spot. Outdoor P7.8 foldable screen: 13 meters wide X 8 meters high

Mechanical difficulties: The diameter of the two lifting columns is about 0.8 meters, and the span between them is about 10 meters. It is necessary to ensure the synchronization of the lifting level between the two lifting columns. The most difficult part of this project is the folding of the machine and the screen. Mutual cooperation between the machine. No manual intervention is required when the machine is lifted and lowered, and remote operation is realized.

 Highlights of LED folding screen:

1. The screen is composed of 13 units, each unit does not need cabinets and air conditioning to dissipate heat, and the connections between the screens are all connected by wire ropes.

2. The control card is embedded: the control system of the screen is all embedded in the module, and the screen is ultra-thin and foldable.

3. Centralized power supply mode. There is no power on the back of the screen. The power supply adopts Huawei‘s top module technology. All the power supplies are supplied through the 48V transmission power supply method, which can guarantee that the screen will not have power supply failure for 10 years.

Fourth, wind resistance level 10. The screen is located at the entrance of the scenic spot, which is also where the wind vent is. The screen is ultra-light and ultra-thin. The back of each single screenless screen adopts 4.0 steel wire rope + track for traction. It not only protects the screen‘s lifting and lowering, but also protects the screen‘s resistance to wind.

5. Control method: Considering that the site is a steep mountain, the control room is arranged under the screen and the operation is not humanized, so the latest cloud control technology is adopted. Implement remote operations at a distance of several hundred meters.

6. When the screen is not in use, it can be stored in the storage box under the bottom to prevent the rocks from falling off later and causing damage to the screen.

 In addition, according to the editor‘s understanding, the scenic spot has invested a total of 12.86 billion yuan, of which Aba Prefecture has invested a total of 5.35 billion yuan, and 11 key cultural and tourism projects have been completed. Road access, comprehensive carrying capacity, supporting services, and disaster prevention and mitigation capabilities have been significantly enhanced. The reconstruction of 26,600 square meters of three-dimensional tourist service facilities at Mizoguchi can pass 10,000 tourists per hour through the double-layer three-dimensional building. The congestion of tourists entering the scenic spot during the peak tourist period will be greatly eased. The total number of reconstructed roads in the scenic spot is 65 kilometers. , Widen the plank road by 60 kilometers, and add multiple parking lots, rest pavilions, environmentally friendly toilets and other infrastructure.
