The hottest industrial manufacturing moves towards

Industrial manufacturing moves towards green and smart

as a barometer of the trend of the world's industrial industry, this year's Hannover Industrial Expo highlights two major themes of green and smart

building a smart metropolis

rapid and efficient communication between transportation systems, energy systems, water systems, public service systems and building systems

the 21st century is called the urban century. It is expected that 70% of the earth's population will live in cities by 2050. Rapid urbanization, economic globalization and climate warming are superimposed on each other, putting pressure on the urban ecosystem. It is estimated that the current urban area accounts for only 1% of the earth, while the annual energy consumption accounts for 75% of the world. European Union Regional Policy Commissioner Hahn pointed out that China faces the most serious challenges in this regard, so cities must become more intelligent

last year, the Hannover Industrial Expo launched the metropolitan solutions Exhibition for the first time, which was widely welcomed by all walks of life. In hall 26 of the current Industrial Expo, the ideas and products of industrial enterprises on urban transportation, construction, energy, water and other issues were intensively displayed

Wilms of the infrastructure and City Department of Siemens said that there is a huge gap between the planning of many cities in the world and the sustainable development goals. Therefore, Siemens established the infrastructure and City Department last year and launched the green city index to comprehensively analyze the indicators of urban water, energy, government governance, air quality, transportation facilities and other aspects. He stressed that the urban green index is not simply good or bad, but to help urban decision makers develop more sustainable solutions

Wilms demonstrated Beijing's green index score: water quality is higher than the world average, carbon dioxide emissions and air quality are lower than the average, and the overall score is medium. Beijing has made great efforts to protect the environment while economic growth, but it still faces environmental challenges. He believes that cities must find a balance between environmental quality, people's living standards and maintaining economic competitiveness, and none of the three is indispensable

Siemens is providing consultation for many cities to find the best balance point or determine the priority development strategy of cities. Barcelona, Spain, for example, accepted the proposal and introduced hybrid buses

why should entrepreneurs do the mayor's job? For this problem, rajile of Schneider Electric Company said that the metropolis solution requires the long-term cooperation of various stakeholders, which also breeds endless business opportunities. There are five systems in the city: transportation system, energy system, water system, public service system and building system. The intelligence of the city is the intellectualization of these five systems, and they communicate with each other quickly and effectively. He said that modern infrastructure is the key to meeting urban challenges, and the first areas to be concerned are energy, water and waste treatment, urban transportation and environmental protection

the French aubar Coastal Development Agency introduced their sustainable regional development plans. In 2005, four coastal cities in France, Dunkirk, Calais, Boulogne and St. Omer, jointly established the aubar Coastal Development Bureau, giving priority to logistics and environmental protection related industries. At present, there are 154 industrial parks in this region, covering offshore wind power, bioenergy, water and waste treatment, ecological materials and other fields

some enterprises and research institutes led by ABB in Switzerland cooperated to demonstrate the smart house system. All electrical appliances in the smart house are controlled by one terminal and communicate with smart electricity to obtain changes in power load and electricity price at any time. In case of power shortage, the terminal can automatically suspend the operation of washing machines and other household appliances; When renewable energy enters electricity, or the electricity price drops, the terminal automatically starts household appliances. Using smart house system can not only reduce carbon dioxide emissions, but also save electricity for families. It is reported that the system has been introduced into the Royal port area reconstruction project in Stockholm, Sweden

improving efficiency means environmental protection

the success of technology in the global market today depends on economic efficiency, quality and safety. Tomorrow, the essence of technology will be the use of resources. There is a product that can help mix glass and nylon efficiency

in many exhibition halls, improving resource efficiency is a banner of green environmental protection. Dr. Feng Ruishi, chairman of the board of directors of Hannover exhibition company in Germany, pointed out that the heated discussion on sustainable development and energy transition is accelerating the process of global industrial innovation, and the global industry is also determined to turn the challenges it faces into development opportunities. Only by skillfully combining efficient processes, environmentally affordable materials and sustainable products, can industrial enterprises remain competitive in the dynamic international market

according to the report of the German electrical and Electronic Manufacturers Association, 80% of the energy from output to consumption is lost in the process of use, transmission and conversion. To reduce this loss, we need to combine energy-saving methods with cost saving measures. Among them, only using process automation can save 15% energy on average

taking cement production as an example, the high energy consumption of the cement industry mainly comes from rotary kilns, in which the ground raw meal is calcined at a high temperature of 1450 ℃. By continuously measuring the contents of oxygen, carbon monoxide, carbon dioxide, nitric oxide and sulfur dioxide with a modern gas analyzer, the best energy-saving value of the rotary kiln can be calculated. At present, more than 200 rotary kilns around the world have adopted this method to optimize the combustion process and reduce carbon dioxide emissions by 20million tons

at present, about 300million motors are used in industrial production worldwide, with an annual growth rate of 10%. Using intelligent automatic energy control, modern energy transmission and electrical components can reduce energy consumption by 30%. This is equivalent to saving 1.7 billion kwh, that is, the annual power generation of 290 nuclear power stations. Toshiba Mitsubishi Electric has recently launched tmdrive mvg2 high-voltage inverter, which further improves energy-saving efficiency

Paulson of the innovation Department of Germany ContiTech told this newspaper: energy saving is income generation. The company introduced an industrial thermal insulation rubber with a working temperature between minus 50 ℃ and 250 ℃. Compared with ordinary thermal insulation materials, its biggest feature is that it can deform freely and is easy to repair, which is suitable for complex surrounding pipelines

Paulson compared a 20-30 cm long pipeline and said that some machines transmit high heat. Assuming that it maintains a high temperature of 200 ℃ for 365 days a year, without any insulation materials, the heat loss caused in a year is equivalent to 500 euros. Using their thermal insulation materials, the material cost plus the labor cost of one hour is more than 100 euros, and the heat loss can be reduced by up to 70%. This calculation can save 250 euros a year

efficient use of resources requires the guarantee of a set of technical standards. In an interview with this newspaper, Dr. Manfred Blaine, the current CEO of TUV Rheinland, said that the core issue of technology in the past was technical safety. Today, its success in the global market depends on economic efficiency, quality and safety. Tomorrow, the essence of technology will be resource utilization efficiency. The focus of industry will increasingly shift to technical solutions to improve the efficiency of resource utilization, including the efficient use of raw materials, energy and industrial raw materials, as well as financial and human resources, as well as the efficient use of time. Ultimately, while improving efficiency, human society and the natural environment will benefit

Blaine said that China has determined the strategy of building a resource-saving and environment-friendly society, and vigorously cultivate green manufacturing and renewable energy industries. In this regard, TUV Rheinland Group has technical testing experts in related fields. At present, 60% of photovoltaic products in the world are subject to their technical testing. The laboratory in Shenzhen has started the testing service of electric vehicle batteries, and the company in Shanghai is also equipped with testing experts for electric vehicle charging systems and auto parts

electric transportation is hot

the common problem faced by the development of electric vehicles is that the battery capacity is insufficient and the price is high. The construction of infrastructure such as charging stations is also crucial

charging stations store electricity through wind and solar power generation to charge electric vehicles, which is an ideal model of zero emissions for green travel in the future. In the electric transportation exhibition area of Hannover Industrial Expo, from various electric vehicle models and concept cars, to renewable energy charging stations, and then to supporting intelligent electrical systems, products and concepts in all links can be described as everything, and the concept of green and intelligent has been expressed in various forms

the small two seat pure electric concept car code named EO displayed by the German artificial intelligence research center appears to be very small, flexible and intelligent. With the signal communication system, each such electric vehicle can be connected in series as a single body to form a connected one-piece vehicle. After being connected in series, the single car with insufficient power can also obtain power from other cars in the same group. After the automatic driving function is added, the control of the vehicle will also be intelligent. After arriving at the destination, passengers can give instructions to the vehicle to find a parking space by themselves

electric vehicles can become a part of the future energy production and distribution that may affect the detection differences of equipment in the operation process, and after the deep-seated adjustment of the consumption structure. In a future home energy intelligent distribution and control system demonstrated by Karlsruhe Institute of technology, electric vehicles are not only power consumers, but also play a role of 12% The function of force storage and adjustment. The home energy control center analyzes the peak and trough data provided by electricity, and decides whether the battery of electric vehicles is charged from electricity or supplied to electricity. This can reverse the instability caused by renewable energy power generation such as wind and solar energy

not only the major traditional automobile manufacturers, but also some enterprises, universities and scientific research institutions in related industries participate in the research and development of electric vehicles. Siemens, a German industrial giant, exhibited the pure electric vehicle samples developed in cooperation with RUF, a German Porsche car refitting enterprise, which are mainly used to test and study the charging stations and other supporting facilities of electric vehicles in the future

the future of electric vehicles is very attractive, but there is still a long way to go to realize this ideal. Wallersheim, an expert of the German Association of electrical and electronic manufacturers, told this newspaper that although major automobile manufacturers are launching pure electric vehicles, the common problem faced by the development of electric vehicles is the lack of battery capacity and high prices. Fisher, another expert, said that electric vehicles are the development trend, and it is unclear how they will be realized. In airports, ports and communities, this relatively small-scale application of electric vehicles has been well promoted

in view of this, battery life should be considered in the design of electric vehicles. The pure electric postal concept car exhibited by Volkswagen belongs to the larger model of electric vehicles. The number of batteries has been increased, and it is designed only for driving in urban areas. The Nils single seater concept car, which belongs to Volkswagen, is designed for office workers who commute between urban and suburban areas. Its body is small and light, reducing the burden of batteries. Its 100 km endurance mileage can generally meet the requirements of commuting between urban and suburban areas

infrastructure construction such as urban charging stations is crucial to the development of electric vehicles. Brandenburg in Berlin is one of the four pilot areas of electric transport in Germany. 22 charging stations have been built, with 100 charging piles at each station,
