Chongqing, the hottest city, is fully developing t

Chongqing makes every effort to develop IOT intelligent building and 3D printing

yesterday, the 2013 Chongqing Action Conference of internationally renowned R & D institutions and the Liangjiang international science and technology innovation forum was held, and seven international science and technology cooperation projects were signed, including intelligent building, 3D printing, medical diagnosis and treatment, IOT technology and many other aspects. Vice Mayor Wu Gang attended the meeting and delivered a speech

intelligent buildings can reduce energy consumption by 20%

Chongqing University of Posts and telecommunications, Chuanyi, Hanyang University of South Korea, nestfield company of South Korea, Sifang will jointly build a R & D center to build an industrial IOT R & D base and an industrial base. Wei Min, an associate professor at the school of automation of Chongqing University of Posts and telecommunications, said that the project will involve many fields, such as industrial IOT, intelligent building, smart home and smart electricity

the so-called IOT is actually a communication technology, which is equivalent to making objects communicate with each other. Wei Min said that just like using telephone, 3G wireless communication network is used. To make the equipment in the factory talk with each other, a new communication technology, namely industrial communication technology, is needed

traditional industrial communication technology transmits data to the equipment room through wiring, and then engineers go to the site for inspection and maintenance. After the realization of wireless communication technology, engineers can complete equipment inspection and maintenance through remote monitoring and handheld wireless devices, so as to improve work efficiency

they have made great contributions to the model renovation of experimental machines for so many years.

although the research center is named after the industrial IOT, its technology can also be used for civilian purposes. Wei Jinan gold assay experimental instrument Min said that the standards applied to industry are far from and packaged into modules, so that users do not need to input a large number of test conditions higher than civil standards in the test process. Therefore, industrial IOT technology can be used by intelligent buildings and intelligent electricity

IOT will completely change people's lives, and its energy consumption will be reduced in both industry and civil use. Wei Min said that taking intelligent buildings as an example, using IOT technology can reduce building energy consumption by about 20%, such as reducing the monthly electricity charge from 1000 yuan to 800 yuan

how to reduce building energy consumption? Wei Min explained that saving energy consumption mainly starts from the power consumption link, such as forgetting to turn off the light when going out. With the help of IOT technology, appliances can sense whether there is someone at home. If it is judged that there is no one, the light will slowly fade until it is turned off

at the same time, IOT can automatically analyze building power consumption data and master the law of residential power consumption, when it is high and when it is low. Power companies can intelligently distribute power according to power consumption

in particular, the research center will also jointly promote the formulation of international standards for the industrial IOT, lead the future development direction of the industrial IOT, jointly promote the application of the industrial IOT, improve the level of industrial informatization in Chongqing, and support the establishment of the industrial base of the Chongqing IOT

3D printing technology or making parts for aircraft

3D printing is getting closer to us. It can not only print plastic flowers, toy puppets and other models, but also make aircraft parts. Yesterday, Chongqing University of Arts and Sciences signed a contract with the Royal Melbourne Institute of technology in Australia to build a joint research center for three-dimensional rapid manufacturing jointly built by China and Australia to jointly study high-quality raw material powder for three-dimensional rapid manufacturing, key technologies of rapid prototyping and personalized product customization service mode

compared with 3D printing technology in the current market, we pay more attention to how to apply 3D printing technology to industrial manufacturing. Ma Qian, Professor of advanced manufacturing and materials science at the school of Aeronautics, Royal Melbourne Institute of technology, Australia, said that 3D printing in industrial manufacturing mainly uses light alloy materials, such as titanium alloy and magnesium alloy, which will greatly shorten the production time of some key parts

why can we shorten the production time of key parts? Ma Qian said that the traditional manufacturing steps are cumbersome, not only to manufacture molds, but also to assemble a number of parts. It takes at least 8 to 9 months before and after, and the cost is high. The use of 3D printing technology can be achieved in one step. He said that now more than 300 parts of commercial helicopters can be manufactured using 3D printing technology

however, it will take time for this technology to be popularized. Ma Qian introduced that the cost of light alloy metal powder, especially titanium powder, required for industrial manufacturing is very high. At present, the international price of titanium powder is about 400~800 US dollars/kg, and only European and American countries can produce it at present

the joint construction of research centers can not only realize the technical exchange of 3D talents, but also reduce the cost by developing their own patented metal powder. Stephen, director of the research and Development Office of the Royal Melbourne Institute of technology in Australia, said that China, especially in Sichuan and Chongqing, is rich in titanium, so choosing Chongqing as the research center is convenient for local materials

Ma Qian said that the Royal Melbourne Institute of technology in Australia has invested hundreds of millions of yuan to purchase 3D printing equipment with 38 technical achievements, including a complete set of high-power crankshaft crank arm process design, which has been transformed in Yucheng. These expensive equipment and related core technologies can be open to teachers and students of Chongqing University of Arts and Sciences
