Since the "13th Five-Year Plan" has been released, the smart city and the Internet of Things construction plan once again put the sensor on the cusp. Taking into consideration the current situation, both China and the rest of the world, building a smart community has become an irreversible trend. In this environment, the sensor as a smart city "bridge", will inevitably usher in the industrial explosion.

It is predicted that in another decade, the global smart city will reach 40 billion sensor terminals. There is no doubt that smart cities will become another one hundred billion market in the sensor industry. In the various fields of urban life such as smart grid, intelligent transportation and intelligent security, the substantive construction and pilot planning of relevant smart cities have been gradually carried out.

Application of Sensor in Smart City Construction

The basic requirement of a smart city is that the objects in the city are connected to each other, and each corresponding object needs to be installed on the object that needs to be identified and managed. Therefore, the upgrading of sensors has become the key to the rapid development of smart cities.

Sensor in the application of automatic driving

Let us talk about the hottest nowadays automatic driving area, the use of sensors are up to hundreds of billions of dollars: Auto is almost without human intervention, you can automatically drive the car, it is likely to represent the driving trend of the future. According to IHS Automotive Research, the automotive sensor market that helped create this engineering miracle has now emerged and will maintain its rapid growth in the coming years.

For example: Speaking from the most basic part of the autonomous driving field, according to the 2016-2021 China high-end sensor market demand and investment planning analysis of the data, parking sensor and lane departure warning sensor, but will appear in the automatic driving applications The two types of sensors in the next five years are expected to grow strongly each year.

Sensor in the application of intelligent transportation

The intelligent transportation system can enhance the information, intelligence, integration and networking of the transportation system by intelligently changing the traditional transportation system and collecting traffic information, traffic, noise, pavement, traffic accidents, weather and temperature intelligently so as to protect people, Vehicles, roads and the environment of mutual exchanges, and thus improve the transport system efficiency, mobility, safety, accessibility, economy, to protect the environment and reduce energy consumption.

The sensor network formed by the sensor can provide an effective means for the intelligent traffic system to collect information, detect the vehicles in the direction of each intersection, and improve the simplification, signal control and traffic efficiency according to the test results, so as to truly solve the problems of urban traffic safety , Smooth and other issues.

Sensor in the smart grid applications

The application of the sensor in the smart grid is to use the sensor to make quick and direct measurement of the quality and fault location of some power products and carry out on-line monitoring. Currently advocated smart city, the concept of smart grid, its fundamental: the establishment of smart grid terminal power information collection system, largely refers to the construction of sensor networks, smart grid, directly led the sensor market, at the same time, in order to Is to meet the future needs of smart grid upgrade, power system sensors are also thinking of intelligent, systematic and networked.

Smart city construction typical case

Since the early 21st century, the United States, Britain, Germany, Japan and other countries carried out the first step of the practice of smart city, and many classic cases were born. Next, Xiao Bian will come to you a brief introduction of several smart city case, let you get a glimpse of the status quo and future of smart city construction abroad.

Songdo, South Korea

South Korea has been at the forefront of countries applying new technologies, which have the world's fastest-growing consumer Internet and whose culture is also very much in favor of new technologies. Therefore, it is not surprising that South Korea became one of the first countries to try to create a smart city by tapping the potential of the Internet. In 2001, South Korea took the lead in establishing a high-tech city for people to live in through the reclamation of the sea: Songdo. In Matsushima, full access to networked power facilities not only provides city managers with usage information on current capacity, but it also helps local residents control their electricity usage. Traffic information sensors are also pre-installed on public roads in Matsushima in order to provide specific details of traffic conditions to urban transport authorities and allow traffic managers to intelligently reset traffic lights to reduce the incidence of traffic jams and traffic accidents , While enabling traffic and flow to achieve the optimal configuration. These "smart roads" are connected to the central control room via the Internet and can play an early warning role before the earthquake.

Santander, Spain

Santander, Spain is a medium-sized town. To reduce air and noise pollution, Santander has started looking for technological help and has become one of the pilot cities for large-scale sensor configurations. By launching the Smart Santander project, the city has deployed about 10,000 electronic surveillance equipment. Each device includes two radio transceivers to communicate with other devices, GPS and sensors to monitor the city's carbon dioxide emissions, noise, temperature, ambient light and even parking in a particular area. Each monitoring device communicates in real time over the Internet so drivers can find the next suitable parking lot via mobile application or smart signal.

United Kingdom Gloucester

The most striking feature of this small British town in building a smart city is its full use of sensors and the establishment of a Smart Home pilot.

In Gloucester City, sensors were installed around the house and the information returned enabled the central computer to control a wide range of home devices. Smart house equipped with computer terminals as the core of the monitoring and communication network, the use of infrared and inductive cushions can automatically monitor the elderly walking around the house. Equipped with medical equipment in the house, the heart rate and blood pressure can be measured for the elderly, and the measurement results are automatically transmitted to the relevant doctors.

American Dubuque

As the first smart city in the United States and also the first smart city in the world, the city of Dubuque is characterized by its emphasis on intelligent construction.

Summary

With the vigorous promotion of smart city construction, the sensor industry will also form a larger market. Experts predict that the next five years, China's sensor market compound annual growth rate will reach 30%. It can be said that the Internet of things, smart city will be the main application of the future market sensor.
