“A warning was issued 6 seconds after the earthquake in Yibin. A notice was sent to 101 communities in Chengdu nearly one minute ahead of time.” Beijing News: What time did the early warning system discover the Yibin earthquake? Wang Wei: An early warning was issued about 6 seconds after the earthquake. The Beijing News: How long is the preparation and decision before the warning?Wang Wei: It is calculated by the early warning system. When the warning intensity is greater than the set value, an alarm will be issued, and an alarm of different sounds will be issued according to the magnitude of the intensity. Beijing News: How to judge the scope of earthquake warning notice? How many kinds of warning notices have been issued in this form?
At the time of the earthquake, the earthquake warning network simultaneously issued earthquake warning information to the unspecified public such as the government and emergency departments, towns, communities, schools, television, mobile phones and media. According to preliminary statistics, 212 schools in Yibin City, Leshan City, Chengdu City, Liangshan Prefecture, Deyang City, Meishan City, Ziyang City, Ya'an City, and Zhaotong City of Yunnan Province issued early warnings from 0 seconds to 57 seconds. 101 communities in Chengdu issued an early warning 57-68 seconds. A total of 79 districts and counties in 13 cities and prefectures such as Yibin City, Leshan City, and Chengdu City have opened TV earthquake warnings or warnings in areas where radio and television and Internet TV earthquake warnings have been issued. Four rural towns in three counties, including Zhaotong City of Yunnan Province, Yibin City of Sichuan Province and Ya'an City of Sichuan Province, issued an early warning from 7 seconds to 65 seconds.
Yibin City, Xian County, Nanxi District, Xingwen County, Pingshan County Hospital (health hospital), Leshan City People's Hospital, etc. received an early warning 4-43 seconds. Major projects such as Xichang Satellite Launch Center, a nuclear reactor, Pengzhou Petrochemical, Chengxiang Chemical, Chengdu Railway Bureau, Chengdu, Ya'an and Liangshan Power received early warnings 10 to 78 seconds in advance. "The system response time is globally leading. In the future, at most 3 seconds early warning." Have you evaluated the effect of this warning? For example, how much life and property have been saved?
Wang Wei: Property is not necessarily, because the general warning does not directly control the property, it can only be said to save people, so that people can avoid danger. Yesterday's warning effect completely met expectations from a technical point of view. First, after the alarm was issued, whether it was a TV, a mobile phone, a big horn, or other forms, the people should have received it. Second, many people have carried out emergency hedging after receiving warnings. Third, after the people received the warning, they did not know that this was an earthquake warning. This is the lack of our science, and the next step is to strengthen science. Of course, through yesterday’s incident, the people knew the earthquake warning, and they have already been popularized. However, this kind of popular science is a bad way. It should be well-organized and can effectively use earthquake warning in the event of a disaster. .
The Beijing News: There is a voice that the earthquake warning is up to 61 seconds early, and some 20 seconds earlier. The time is too short. It is too late to transfer or evacuate. It does not seem to solve the problem. What do you think of it? Wang Wei: This is determined by the principle of the early warning system. It is not how much you want to advance. The warning time of this early warning system is already the best in the world, and we have not done it in other parts of the world that we can't do. The Beijing News: Compared with Europe and the United States, this system is mainly in which aspects, which technical indicators are leading?
Wang Wei: Our technical indicators are in a leading position in the world, mainly reflected in higher response time and reliability than foreign countries. Beijing News: Can we predict the earthquake earlier? For example, ten minutes in advance? Wang Wei: Two or three seconds is possible. It is not enough to advance more. The system covers the Jiucheng earthquake zone.
Beijing News: At present, how many areas and populations have covered the system? What is the estimated size of the application? Wang Wei: Covering 90% of the population in China's earthquake zone. The Beijing News: In the past warnings, is there any error? If you report an error, is it more panic? Wang Wei: I haven't got it until today, but I don't rule out coming tonight. Because there is a possibility of false positives in probability. We must continue to improve our technical level so as to ensure that earthquake warning technology will not be misreported in the future.
The Beijing News: There is a voice that the land earthquake warning effect is not as effective as the ocean earthquake. Is this the case? Wang Wei: This view has always existed. The principle of earthquake warning is very simple, it is shock wave, there is no scientific principle. But it can minimize casualties. Beijing News: What are the blind spots in the application of earthquake warning technology? Wang Wei: Yes, the warning speed in the area close to the epicenter is zero. The blind spot is probably within 21 km of the epicenter. People within 21 km will feel the earthquake before receiving the warning.
Beijing News: I downloaded the "earthquake warning" APP and found that I can't register? And the reminder value of the magnitude and intensity is not very high, about 5 levels? Wang Wei: You can use it without registration. In addition, our main work direction is to connect the earthquake warning function to other large APPs, such as WeChat, QQ, Alipay, etc. After all, our own APP is no better, the people will not care too much, and usually will not go. Download, so you have to add this extremely low frequency function to the usual APP. “The results of the research institute are transformed into Vision Technology, and we hope to build the first listed company in the field of disaster warning in the country”
Beijing News: The relationship between Chengdu High-tech Disaster Reduction Research Institute and Vision Technology? Wang Wei: Because earthquake warning involves both public welfare services and major basic research and international exchanges, it is very suitable in the name of disaster reduction. Earthquake early warning also involves some commercial work, such as installing earthquake warning terminals in schools, communities, and factories. The hardware of receiving terminals for installing earthquake warnings is charged. Because the Institute is a private non-enterprise unit, in this case it is not possible to charge, it is to transform this achievement in the magic technology.
Beijing News: Is it considering listing for the Fantasy Technology Financing? Is there a timetable? Wang Wei: There is no timetable. We especially hope to build the first and even the world's first listed company in the single sector, so it will be a work direction in the future. The Beijing News: Can you say that you want Vision Technology to become the first commercial earthquake company?
Wang Wei: We can't say that disaster warnings are not only public, but also commercial and industrial. In fact, we must grasp its own laws when doing anything, not what I want to do. After many fire incidents in Tesla and Weilai Automobile, the Chinese government is asking new energy vehicle manufacturers to strengthen the safety investigation of electric vehicles. This has raised concerns about the safety of battery-powered vehicles.
The Equipment Industry Development Center of the Ministry of Industry and Information Technology of China stated that enterprises need to focus on the waterproof protection of sold vehicles and inventory vehicles, high-voltage wiring harnesses, vehicle collisions, vehicle power batteries, vehicle charging devices, battery boxes, mechanical parts and wearing parts. Safety hazard investigation work. Major new energy vehicle manufacturers need to submit inspection results by the end of October.
In China, the world's largest new energy vehicle market, a series of fires have occurred in electric vehicles. Weilai ES8 has had three fire accidents in the past two months. On June 14, a Weilai ES8 burned in the parking lot of Hanxi Building Materials Market in Wuhan, Hubei. On May 16, a Weilai ES8 spontaneously ignited in the underground parking garage in a residential area in Anting Town, Jiading, Shanghai. Earlier on April 22, a repaired ES8 in Xi'an Weilai authorized service center burned.
On April 21st, the Tesla electric car suddenly exploded in Shanghai, causing many luxury cars in the garage to burn or be damaged. A few weeks later, there was a report that a Tesla Model S caught fire in Hong Kong. The specific cause of the fire is currently under investigation. As market demand rises, electric vehicles are increasingly using high-density lithium batteries to extend mileage. Subsidies and preferential policies have pushed China's electric vehicle sales to more than 1 million units last year.
According to data from the State Administration of Markets, in 2018, at least 40 fire accidents involving new energy vehicles occurred in China. New energy vehicles include pure battery electric vehicles, hybrid plug-in vehicles and fuel cell vehicles. The regulator has asked for a review of the quality of new energy vehicles and recalled more than 130,000 vehicles last year.
Of course, China is not the only place where electric cars are on fire. On June 10, Audi said that due to the risk of battery fire, the first pure electric vehicle sold in the United States will be recalled. Approximately 540 E-Tron SUVs were actively recalled because of the risk of moisture penetrating into the battery through harness failure. Audi spokesperson Udo Ruegheimer said last week that he is negotiating with the German authorities on possible European recalls.
According to a US report in 2017, electric vehicles are no more prone to accidents or fires than gasoline cars, and there may be fewer possibilities for a fire. But the report also pointed out that battery technology is still evolving, and there are no defects in the design of the safety system. In Japan, in order to make people more aware of what is garbage classification, every time you move to a community, the property will give you a thick handbook of garbage dumping, with pictures and texts, and the details are as high as 500 items. For example, the carton must be taken apart and laid flat and bundled; the wire plug must be bundled with the appliance; the length of the stick should not exceed 50 cm; the kitchen waste needs to be drained and wrapped in newspapers; the barbed or sharp items should be used. The paper is wrapped and labeled; the used spray can has a hole to prevent explosion; the edible oil needs to be wiped clean with a rag, and the bottle must be sealed with a newspaper...
This is the Japanese, both serious and true. There are some rules that are simply unbelievable. For example, a used envelope cannot be counted as waste paper because it has residual glue. Before throwing off the can lid, the rubber pad embedded in it should be removed first. Discarding a bicycle must be attached. The last note "This is what I don't want"; socks, only one is combustible, if there are two and "not worn, left and right feet" then upgrade to "old clothes"...
If the above details have already made you crazy, then the following treatment of liquid waste will definitely make you madly scratch the wall - in Japan, after eating, the dishes must first use the waste newspaper (Reassured, Japan The ink is made of soybeans. It is cleaned and then cleaned. This prevents oil that is not easily decomposed from flowing into the sewer and also reduces the use of chemical detergents. Japanese supermarkets even specialize in selling a coagulant for kitchen oil stains. Just squeeze a drop and the oil will condense into a piece of amber. Amber is a "burnable garbage", but it must be wrapped into a flat angle with waste paper before it is thrown.
Behind the tutorial, there is also a rainbow calendar – each color represents which type of garbage can be thrown on that day. For example, non-burnable garbage will be collected on Monday morning, and resource garbage will be collected on Tuesday morning. It seems to be orderly and reasonable, but for the residents this means the fish that was eaten on Monday, until the bones can be spit on Thursday, and the clockwork must be tightened at that time - because even on that day, it is not any Time is fine. Many communities stipulate that garbage will be thrown before 8 o'clock in the morning. Because there are many Japanese crows, the garbage bags will be smashed to cause secondary pollution. If you miss the time, you can only take it home for a week of reincarnation.
Many foreign students who are new to Japan are too troublesome, and they are lucky enough to throw litter, but they don’t know that Japan is full of monitoring teams, all of which are composed of volunteers. Their duty is to search illegal garbage bags and send illegal garbage back to the owner. Home, and remind the owner to deliver in the right way. In the face of such a shameful thing, international students can't even excuse themselves not knowing Japanese, because Japanese, Korean and Chinese are clearly printed on the trash cans in the manual and in the community! Every time I move, the agent and the landlord will explain the garbage classification Dafa with the tenant patiently and in detail, and make sure that the other party understands and guarantees the execution. Only then can the key be handed over and then squatted deeply. Just ask you."
There is very little occupational discrimination in Japan, but if you don't dump garbage and destroy public health, you will be blinded. Generally, foreign students have never had the will to be heard after they have been knocked on by the monitoring team. After all, garbage is small and it is a big problem. The most impressive thing was that once from the izakaya, the boss gave a congratulation to the back and found a girl on the side of the road crying. Next to it was an eye-catching Akita dog, who did something wrong and pulled his head. The boss knelt down and asked the girl why she was crying. The girl’s shoulders said something, the boss smiled and turned and took a bottle of water and a pack of paper from the store. The girl saw it, and immediately burst into laughter, and kept acknowledging.
My friend told me that the girl’s Akita dog had a diarrhea, and the paper and water she carried with him was not enough to clean the floor, so she was so anxious to cry – in Japan, every dog who walks the dog must bring “four treasures”: paper , water, clips, plastic bags. This means that the dog owner can't just pick up the poop and finish it, but also clean the floor water to be a merit. Although the trouble, but the harvest is also obvious - people who first arrived in Japan will be surprised that the city is clean and tidy, even the water on the rainy road is crystal clear, even if you accidentally splash the rain on the trousers, don't worry, the sky is clear, They have no trace.
Once, I went shopping with a Chinese friend who lived in Japan for a long time. My friend looked at a simple coat and hesitated. I only know that this jacket has no pockets and it is not convenient to go out. The first thing that the Japanese go home is to change the shoes while picking up the garbage from the pocket: tickets, toilet paper, orange peel, bags, Beverage bottles... There are a lot of people, Lala is mixed, and then they do not bother to sort them out, and then merge the same items. Finally, they are thrown into different garbage bags. This set of movements is done as a natural and smooth way by friends.
