On the afternoon of the 16th, the No. 22 typhoon 'Hawthorn' officially landed in Guangdong. The maximum wind force near the center at the time of landing was 14 and it became the strongest typhoon in China this year. According to the latest report, as of 20:00 on the 16th, the typhoon 'Hawthorn' has led Two people died in Guangdong Province, and 15 people were injured in Macau. It is really sad!
In the past two days, the news related to 'Hawthorn' has blown up the circle of friends, which has aroused the attention of the people of the whole country. At present, the high-speed rail in Guangdong Province has been suspended, and a large number of flights have been cancelled in Shenzhen, Zhuhai and Guangzhou airports, and many stops have been suspended. Always maintain the wind-proof class I emergency response, continue to go all out to do the typhoon 'mangosteen' defense work.
In the face of natural disasters, life always seems to be vulnerable. The arrival of the 14th typhoon is not only a strong wind force, but also a huge threat to the personal safety of pedestrians. In the storm, the text ads installed at high places brand, LED display , LED light boxes, etc. Outdoor Advertising The card also lurks in a huge crisis. Especially in Guangdong, where the economic level is among the best in the country, the number of outdoor LED advertising screens covers two-thirds of the national advertising market share, large and heavy. LED display Once the screen is fired or dropped, it will have unpredictable consequences.
The arrival of typhoon weather, for outdoor LED display The performance of all aspects of the screen brings great challenges. In the outdoor environment, in order to ensure that it will not be eroded by rain, the LED display itself needs to have a high degree of waterproof protection, and the module must be filled with glue, and the waterproof box is selected. The waterproofing rubber ring is used to connect the module and the box; at the same time, the outdoor LED advertising screen is installed in many places, and the installation method is also very diverse, with wall-mounted, inlaid, column-type, hanging type, etc. Typhoon In order to prevent the LED advertising screen equipment from falling, there is a strict requirement for the load-bearing steel frame structure of the display screen. This requires the engineering unit to strictly design and install according to the typhoon-resistant standard. The seismic capacity, in order to ensure that the outdoor LED display will not fall, causing secondary harm to personnel.
More importantly, in the typhoon season, the impact of lightning on the LED display is fatal. If it is hit by lightning, the display will be seriously damaged. Therefore, the outdoor LED display must be equipped with lightning protection lightning protection equipment such as lightning rods. Grounding, install the power supply lightning arrester in the distribution box, and then ground, to ensure the safety of the outdoor LED display.
In order to confront the typhoon 'Hawthorn', two days before the typhoon landed, all areas in Guangdong were inspecting safety hazards. In Guangdong, Foshan and other places, relevant departments conducted comprehensive investigations on various outdoor advertising facilities, and found outdoor advertising. If the facilities are outdated, incomplete, falling off, collapsed, and not in accordance with the approved specifications, form settings, etc., immediately notify the setter to rectify in time, immediately take the forced removal if the rectification is not in place or refuse to rectify, and impose penalties according to law to fully protect the citizens' personalities. And property security.
However, there are disadvantages in everything. Although the outdoor LED display has certain dangers in typhoon weather, with the improvement of technology and the return of the quality consciousness of LED manufacturers, the safety factor of all aspects of LED display has been greatly improved. It not only reduces the incidence of accidents, but also has the advantage of high resolution and diversity of communication information, and has become a powerful 'small horn' against the typhoon war. For example, before the landing of 'Hawthorn', Dongguan At the border checkpoint, Changping station passed the LED display screen to play the customs clearance reminder to release the travel reminder to the passengers. When Typhoon 'Maria' was logged in, relevant departments passed various measures such as LED rolling promotion, WeChat group sending, etc. Predict and early warning, strengthen pre-judgment prevention, and firmly grasp the initiative of flood prevention work.
According to the release of the Central Meteorological Observatory, after the typhoon 'Hawthorn' landed, it continued to move toward the southwest Yangjiang River, and the wind continued to weaken. The Guangdong Provincial Defense General lowered the wind-proof Class I emergency response to Class II at 20:00 on the 16th. In any case, prevent the problem forever It is the best. In the season when the typhoon is frequent, the outdoor LED advertising screen is relatively fragile as an electronic device. If the outdoor LED advertising screen is damaged due to failure to protect it, it is not only economic loss, but also may cause personal injury. Therefore, there is no small matter in safety, and we must deal with all kinds of sudden natural situations.
