It is understood that the shooting project has high requirements for lighting, and even one lamp damage may affect the event. Sun Zhenhua, manager of the power facilities of the Beijing Shooting Project Venues, said that he is now fully protected.
Secret 1 use longevity lamp
The lighting facilities in the shooting hall use metal halide lamps, which have good color rendering and long life and can be used for about 1000 hours. These lights are mainly installed above the venue of the qualifiers and finals shooting venues (target roads) and above the audience seats.
Secret 2 install uninterruptible power supply
Shooters are sensitive to light and shooting venues to extinguish a lighting facility can affect the event.
Sun Zhenhua introduced that a three-pronged approach has been taken to prevent power outages during the race: two power sources were introduced from two different locations, and a generator was also activated. If one of the two power supplies is powered off, the other will be connected to the viewer with a blink of an eye. The middle light will not blink. Sun Zhenhua said that UPS (uninterruptible power supply) has been installed for each lighting facility in the venue. If the two power sources are powered off at the same time and the generator is faulty, the UPS can guarantee that the lamp will remain for 30 minutes.
Secret 3 protection work in place
Today, athletes from about 103 countries will be formally trained at the National Shooting Range.
According to Sun Zhenhua, the security work of the venues has been fully in place, and it is currently the running-in between media broadcasters and competitions. For the broadcast effect, the broadcaster hopes that the light will be as bright as possible, but the competition should consider the athlete's ability to bear more.
Secret 4 Difficulties are the media area
Sun Zhenhua said that it is difficult to control the media area. Journalists will bring laptops and some equipment. The insertion and removal of equipment may cause a power supply to trip. Sun Zhenhua said that reporters have been required to use electrical equipment that meets the standards during the event, and the use of unqualified electrical appliances will be restricted.
It is understood that problems in the region will not affect other regions.
