The hottest new and high technology integrated int

  • Detail

High and new technology integrated into the Expo robot solar energy and other exhibitions national strength editor's note: the World Expo has been a platform to display new technologies since its birth. Let's see what kind of surprise Shanghai will bring in 2010. Robots, solar energy, LED lighting, energy-saving buildings, RFID, which you may have heard but have not seen, and which you may have seen but have not experienced, will be displayed in the 2010 WorldExpo

come to the Expo to watch the technology show! Robots, solar energy, LED lighting, energy-saving buildings, RFID, which you may have heard but have not seen, and which you may have seen but have not experienced, will be shown in Table 3 of the 2010 WorldExpo. Moreover, every technology is not robot, solar energy, LED lighting, energy-saving buildings, RFID, which you may have heard but still high-grade digital incremental sensors often adopt sinusoidal waveforms. New things you may have seen but never experienced will be displayed in the 2010 WorldExpo. Now the delicate exhibits of "do not touch" in the booth are practical technologies that can be seen everywhere in the Expo Park

the future WorldExpo will present an overall picture in front of the audience. High and new technologies have been integrated into the means of expression, telling their own stories. Therefore, cultural themes, high-tech and beautiful landscapes converge here into a unified perspective, and become the "products" of various countries. Japan's world leading robot technology, Germany's effective utilization of waste, the advanced holographic images of the United Arab Emirates and South Korea, China's large-scale application of solar energy technology, and the country's scientific and technological and environmental protection strength are fully displayed here

just as the Eiffel Tower is the commemoration of the 1889 Paris World Expo, the large-scale application of Expo technology is also an opportunity to promote the technological level and municipal facilities of the host city. It will refresh the face of the host city and change the lives of 18million people in Shanghai in the future. "I don't know whether the new technology displayed after the WorldExpo can make the car exhaust emission less and drive more smoothly? If only the LED lighting in the WorldExpo garden could be used for the street lamp at the door of the home! Will the solar cells in the promotional film be widely used in Shanghai in the future? Will more domestic robots come into our lives after the WorldExpo?" although there is still more than a year to go, However, in the Baidu Post Bar of the 2010 Shanghai WorldExpo, some people are already discussing their concerns and looking forward to the convenience that the WorldExpo will bring to them

indeed, the high-tech show of the WorldExpo should not be just a show. It is the tradition of previous WorldExpo that technology is people-oriented. While counting the many technological applications of this WorldExpo, we also hope to meet them unexpectedly in our daily life on March 17 after the WorldExpo

led lighting

both the lighting of the whole Expo Park and the pavilions of some countries and enterprises all choose led. Will it become popular in Shanghai and even in China? Let's wait and see and make suggestions

it is almost certain that the Expo venue at night will be more charming. The bowl shaped British Pavilion will change colors with the breeze. The pavilion is embedded with LED tentacles extending in all directions, and the small light source is sensitive and diverse; The "sky light" of the Taiwan Pavilion is intertwined with light and shadow through the transparent and luminous outer wall and the huge LED sphere

yes, it's LED. This technology, known as "next generation lighting", is accelerating the "revolution" of light sources. Not only landscape lighting, but also many indoor lighting of the Expo will use LED lights. Nearly 70% of the lights in the whole park will use LED lighting. The night view of the park will also be divided by the intensity and color of LED lights

LED lamps with a life of 66.7 times that of ordinary incandescent lamps only need 1/6 to 1/8 of the electric energy of incandescent lamps under the same illumination. Because it is electronic diode light-emitting, the cold light source and strong shaping ability of LED also lay the foundation for its first application in display and aesthetics. For people looking for the current application direction of LED, led tentacles and led spheres themselves are a good test ground

however, LED lamps encounter the problem of manufacturing cost in the promotion process. The price of ordinary commercial LED lamps is still about 2000 yuan, while fluorescent energy-saving lamps only need about 100 yuan. In China, what is more serious than technology upgrading to reduce costs is that domestic led enterprises are generally small in scale and have little systematic investment in technology research and development. They can only sit back and watch the rapid improvement of LED lighting efficiency in Philips and Ge research laboratories

the holding of the Olympic Games and the WorldExpo has also brought updates to the urban infrastructure. LED street lights and billboards have entered the government plan. Accordingly, the Expo will also become a stage for domestic enterprises to show their strength, but how to strive for a larger market after the Expo is what they need to consider more

resource recycling

in addition to collecting sunlight and using rainwater, the pavilions in Germany, Finland and other countries use biodegradable and recycled materials. After the Expo, they can be easily removed, and even "evaporated from the world"

the Japanese pavilion in the shape of "lying silkworm" has a huge semi-circular dome and an outer membrane containing solar power. At the same time, the pavilion has the functions of lighting and rainwater collection. Not only a single venue, but also the whole Expo park takes "symbiosis with the environment" as an important concept. The six 35 meter high "sunshine valleys" on the Expo Axis are not only beautiful, but also introduce sunshine, air and rain into the underground space of the Expo venues. The purified rainwater can be used for flushing the facade and toilet

the Expo Axis sits on the Huangpu River, and uses the river water as the cold source of heat pumps and geothermal heat pumps to provide cold and heat sources for air conditioning. In the air conditioning system of the Expo Axis, the replacement rate of tap water reaches more than 50%. After 2010, most of the Expo venues will be demolished, and many of them will use recyclable materials to build "temporary buildings". For example, 12000 square meters of innovative building fabric used for the outer wall of the German Pavilion can be transformed into small sunshades and even handbags. The 16 meter high red curtain outside the Finnish Pavilion is mainly made of soybean fiber fermentation, which can not only generate electricity, but also degrade naturally. It is a pure natural protein material


workers no longer hold handheld terminals to identify QR codes pasted on containers, but only install readers at the door of the warehouse. The system automatically reads storage and transportation information, and even knows the source, nature, destination and other contents of goods

rfid is a kind of electronic tag. Through radio frequency identification technology, the data stored in the tag can be identified by radio signals. RFID has become a revolutionary product of electronic tags because of its manual work, large amount of recorded information and ultra-low misreading rate. The most successful application was in the 2006 German football World Cup. For the first time in the history of the world cup, there was no fake ticket for the month long match. By the 2008 Beijing Olympic Games, the slow admission of spectators caused by anti-terrorism measures has always been the focus of public concern. However, the Olympic Committee adopted chip embedded tickets to successfully solve this problem. When entering the competition venue, ticket holders only need to brush their tickets on the ticket checking instrument, which greatly improves the anti-counterfeiting screening ability and ticket checking speed. Moreover, Olympic tickets also record the purchase time, place, admission time and seating area of tickets, which is more conducive to the safety management of the stadium

RFID will continue to play its role at the Shanghai WorldExpo. The Shanghai Municipal Commission of Commerce revealed that in addition to the application of tickets, RFID technology will also be used in the process of food production, processing, storage and sales. After all, this kind of system that can comprehensively track food from origin to table is a major guarantee for food safety

rfid came to the stage with the help of big events, and people have more expectations for its application in daily life, such as "unmanned store". Because each product is equipped with RFID tags, the management is no longer worried about theft. Only RFID is needed to input the product price to the credit card system for checkout, and even the customer's consumption habits can be statistically analyzed through the product information collected by the RFID system

however, the high manufacturing cost is still a shackle to the promotion of RFID. For electronic labels alone, the general price is more than 200 yuan, while the commonly used QR code is almost zero cost and still meets the requirements of ordinary applications

holographic image

at the WorldExpo, whether it is the "desert oasis" of the United Arab Emirates Pavilion or the "miniature Seoul" of the South Korean Pavilion, are all stages of holographic technology, and the organizers will interpret their own stories through the combination of physical objects and images

at the 2005 Aichi WorldExpo, Japanese life movement, which pays attention to details, explained the experience of visiting. The "landscape dream" pavilion has a 360 degree angle of view, with images on the floor and walls. The public can freely change their sights to browse Japan's famous mountains and rivers. These precious experiences come from "holographic imaging technology". This technology uses the principles of interference and diffraction to record and reproduce the real three-dimensional image of the object. The hologram is like a complex grating, which records the light information of each point on the object in each part, so it can reproduce the original object. With the evolution of holographic technology in recent years, holographic images that allow the audience to take off their glasses appear

and the image carrier has also developed from the original large screen to a variety of media. For example, fog screen imaging is to use the principle of aerodynamics to create a plane fog body, and then let it become a light carrier to create an illusory three-dimensional image out of thin air. People can even shuttle through the image at will. Some time ago, the holographic image of "sanshuishui" at the closing ceremony of the National Games took more than 3000 thin lines hanging from the height of the stadium as the "screen"

straw house

real estate enterprise Vanke will build a house with straw, which will become a part of Vanke exhibition hall. This is not a fantasy. Compressing straw into boards with qualified hardness and density can not only save wood, but also protect the environment

On July 29, at the foundation laying ceremony of the Vanke Pavilion of the WorldExpo, Wang Shi, chairman of Vanke Group, pointed to a pile of straw and announced that he would use them to build a house here and show it to 70million tourists from around the world. Is Wang Shi going to use a thatched cottage to demonstrate Du Fu's song "thatched cottage broken by autumn wind"? Of course not. Behind the largest real estate enterprise in China, stands a small enterprise, lindson board in the Netherlands, which has just been established for less than three years. This company has a unique patented technology, which can press wheat straw into plates with higher density than wood

its research center invented the technology called "directional straw structural board". After the cylindrical straw is split into strips, it is arranged and compressed in a certain direction, and combined with the bonding of a special zero formaldehyde glue, the produced board is equal to the hardest and densest board on the market in terms of hardness and density, so it can completely replace any wood. This is almost a perfect solution - it can not only turn straw into treasure, but also solve the problem of formaldehyde volatilization of most composite boards in the market, and protect the forest

new energy

although China has become the largest producer of solar photovoltaic cells, it is obvious that its domestic promotion is not enough. Extensive in the Expo Park
