The hottest trillion sensor revolution promotes so

  • Detail

Trillion sensor revolution improves social public services

in 2014, sensors have attracted more and more attention from the whole society, and many countries began to put forward the slogan of trillion sensor

the United States: first put forward the idea of "trillions of sensors revolution"

the popularization process of trillions of sensors "

trillions of sensors revolution", which first appeared at the trillions of sensors summit of the joint conference of industry and University in the United States

the meeting was co chaired by Janusz bryzek, vice president of Fairchild Semiconductor, Albert P. Pisano, Dean of the University of California San Diego School of technology, and others. Many famous enterprises and organizations from ICT (information and communication technology), parts (semiconductor, electronic components) industries, universities and research institutions supported and participated in the conference

the trillion sensors universe plan was proposed at the conference to promote the use of 1trillion sensors in social infrastructure and public services every year (Figure 1). 1trillion, which is equivalent to 100 times of the current global sensor market demand. It can be predicted that in the near future, sensors will be everywhere around us

10 years later, the number of sensors will exceed 1trillion; In another 10 years, it will reach 10 trillion

Japan: launched a number of large-scale sensor application plans

Japan has many social and public service problems to deal with in the future due to aging social infrastructure, increasing elderly population and insufficient resources and food. In april2013, the Ministry of economy, industry and trade of Japan launched the application and development project of sensor technology in social public services. The project involves the maintenance and management of bridges and roads built and used for more than 10 years, the improvement of crop cultivation environment, and the timely detection of diseases through the measurement of human physical signs

in July, 2013, Japan's new energy industry technology Comprehensive Development Agency (NEDO) announced the entrusted research institution of the project. Among them, the fields of social and industrial infrastructure are led by Japan nano Optoelectronic Engineering promotion agency, NEC and Japan capital Expressway technology center; The agricultural field is led by the Japanese Institute of industrial technology and Panasonic; In the field of medical and health care, Japan's nmems Technology Research Institute is responsible. It is planned to set up kostron in April 2014 to continue the research and development of polyurethane foam. The newly revised national mandatory standard for plastic runway will be formally implemented from November 1. The project team will analyze a large amount of data collected from sensors through computers

on June 14, 2013, the Japanese cabinet meeting adopted the Declaration on building the world's most advanced it country for Japan's future IT strategy. The declaration proposed to use sensors to detect and repair 20% of Japan's important infrastructure and aging infrastructure by 2020, and to develop, verify and commercialize sensor technologies and robot (49.100, -0.58, -1.17%) technologies related to medical care and life assistance services

the core of the future social infrastructure is the sensor and the executive ergodic curve generator

in a broad sense, the social infrastructure specifically includes: (1) the management and security of buildings, residences, bridges, dams and other buildings; (2) Safety guarantee of railway, ship, aircraft, automobile and other means of transportation; (3) Human health management and elderly population nursing; (4) Improve the efficiency of primary industries such as agriculture and animal husbandry; (5) Maintenance of energy related infrastructure, etc

use sensors, big data, etc. to solve social and public service problems

the blue object in the above figure is the vibration sensor of Japan Fuji Electric, and the lower left is the company building where this sensor is installed; The social public service element in the middle is the soil nutrient sensor of Toyohashi University of technology and Science in Japan. The arrow corresponds to the farmland where the sensor is installed; The social public service element on the right is the electrode of the University of Bremen in Germany that can act on human nerves, etc., and the arrow corresponds to the fingers of the people photographed by the Japanese Roma company with the near-infrared image sensor

regardless of the field, the future system composition is basically the same (Figure 2). First, numerous sensors connected by networks should be installed on the targeted infrastructure to collect data about the status of the infrastructure. Then, according to the collected data, evaluate the use status of the infrastructure, and give an alarm if necessary, or carry out appropriate regulation. For example, when monitoring bridges and buildings, optical fiber sensors and acceleration sensors are used to collect building data, and mathematical statistical methods are used to analyze whether there is any abnormality. If there is any problem, an alarm will be given

such systems are called sensor networks or iots. This concept existed long ago, but it has not been really popularized. Now, due to the large-scale application of sensors, the situation is changing

the continuous improvement of the technical environment will also accelerate the use of sensors. Smart is very easy to use because it is equipped with an acceleration sensor and a wireless communication module. In terms of communication technology, in addition to WLAN and Bluetooth, some countries have planned 920mhz band, and there are more and more choices of wireless communication methods. Data analysis technology has also developed rapidly due to the increased use of big data

at the same time, with the maturity of open data management methods, open data and sensor data want to be analyzed together, which will give more added value to the analysis results. Open data refers to meteorological data, basic urban data, population dynamics, etc. Cloud computing can be used to collect the data collected by sensors for the pressure plate, turbine disk, blade, bearing ring, gearbox, fastener and plate welded bearing parts of aeroengines, and compare them with open data. After the analysis by big data technology, the accuracy of various analyses can be improved

it can be said that in social infrastructure and social public services, sensor systems will be adopted on a large scale due to extensive sensing and powerful computing power
