The hottest trillion sensor revolution improves so

Trillion sensor revolution improves social public services

in 2013, sensors received new attention from the whole society, and many countries began to put forward the slogan of trillion sensor

United States: first put forward the concept of the trillion sensor revolution

the popularization process of trillion sensors

the trillion sensor revolution, which first appeared at the tsensors 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 and components (semiconductors, electronic components) industries, universities and research institutions supported and participated in the conference

the trillion sensors universe plan was proposed at the meeting to promote the use of 1trillion sensors per year in social infrastructure and public services (Figure 1). 1 trillion, which is equivalent to 100 times the current demand of the global sensor market. It can be predicted that in the near future, DC electromechanical speed control and feedback conditioning will be full of sensors around us

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

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

aging social infrastructure, increasing elderly population, coupled with the lack of resources and food, Japan needs to deal with many social and public service problems in the future. In April, 2013, the Ministry of economy, trade and industry of Japan launched the application and development project of sensor technology in social public services, which 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 to restore the research institution entrusted by the project. Among them, the fields of social and industrial infrastructure are led by Japan's nano Optoelectronic Engineering promotion agency, NEC and Japan's 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, Japan's nmems Technology Research Institute is responsible, and plans to establish a special project team in April 2014 to 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, which proposed the goals of using sensors to detect and repair 20% of Japan's important infrastructure and aging infrastructure, and the development, verification and commercialization of sensor technology and robot (49.100, -0.58, -1.17%) technology related to medical care and life assistance services by 2020

the core of the future social infrastructure is sensors and actuators

in a broad sense, 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

solve social public service problems by using the lead screw feature introducer and big data of the sensing hydraulic universal testing machine

the blue object in the above figure is the vibration sensor of Fuji Electric in Japan, and the company building where this sensor is installed is on the lower left; The social public service element in the middle is the soil nutrient sensor of Toyohashi University of technology and Science in Japan, and the arrow corresponds to the farmland where this 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 human finger photographed by the Japanese Roma company with the near-infrared image sensor

regardless of which field, the future system composition is basically the same (Figure 2). First, countless sensors connected by networks should be installed on the infrastructure as an object 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 or carry out appropriate regulation if necessary. 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 are abnormalities. If there are problems, an alarm will be sent

such a system that supports domestic enterprises to participate in international competition is called sensor network or IOT. 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. Intelligent is very easy to use because it is equipped with acceleration sensors and wireless communication modules. 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, the combination of open data and sensor data will give more added value to the analysis results. Open data refers to meteorological data, basic urban data, population dynamics, etc. Cloud computing collects the data collected by sensors and compares it with open data. After being analyzed by big data technology, it can improve the accuracy of various analyses

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.
