Since the publication of the 13th Five-Year Plan, the construction plan of smart cities and the Internet of Things has once again pushed the sensors to the forefront. In the current situation, whether it is China or the world, building a smart community has become an irreversible trend. In this environment, the sensor as a "bridge" of a smart city will inevitably usher in an industrial explosion.

It is predicted that in the next decade, the number of sensor terminals connected to smart cities worldwide will reach 40 billion. There is no doubt that smart cities will become another billion-dollar market for the sensor industry. In the fields of smart grid, intelligent transportation, intelligent security and other urban life, the substantive construction and pilot planning of relevant smart cities have been gradually carried out.

Application of sensors in the construction of smart cities

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

Sensor application in automatic driving

Let's talk about the most popular auto-driving field at present. The sensor usage scale is more than 100 billion yuan: Auto-vehicle refers to a car that can drive automatically without manual intervention. It is likely to represent the driving trend of the future. According to IHS's automotive research report, the automotive sensor market that has helped create this engineering miracle has emerged and will continue to grow at a rapid rate in the next few years.

For example, from the most basic part of the autonomous driving field, according to the data of China's high-end sensor industry market demand and investment planning analysis report for 2016-2021, parking assist sensors and lane departure warning sensors will only appear in autonomous driving applications. Two of the sensors in the world are expected to grow strongly each year for the next five years.

Sensor application in smart transportation

Through the transformation of the traditional transportation system, the intelligent transportation system enhances the informationization, intelligence, integration and networking of the transportation system, intelligently collects traffic information, traffic, noise, road surface, traffic accidents, weather, temperature, etc., thereby protecting people, The interaction between the car, the road and the environment, thereby improving the efficiency, mobility, safety, accessibility and economy of the transportation system, and achieving the effect of protecting the environment and reducing energy consumption.

The sensor network composed of sensors can provide an effective means for information collection of intelligent transportation systems, detect vehicles in the direction of each intersection, and improve simplification, improve signal control and improve traffic efficiency according to the detection results, and truly solve the problem of plaguing urban traffic. , unobstructed and other issues.

Sensor application in smart grid

The application of sensors in smart grids is to use sensors to quickly and directly measure the quality and fault location of certain power products and conduct online monitoring. At present, the concept of smart city and smart grid advocated is fundamental: the terminal power information collection system needed to build a smart grid largely refers to the sensor network, the construction of smart grid directly drives the sensor market, and at the same time, It is to meet the needs of smart grid upgrades in the future, and power system sensors are also thinking about smart, systematic, and networked.

From the US spending on smart grids in the picture below, we find that the domestic smart grid still has a large market space, and the application of sensors on the smart grid has just begun!

Typical case of smart city construction

Since the beginning of the 21st century, the United States, Britain, Germany, Japan and other countries have carried out the practice of smart cities first, and many classic cases have been born. Next, Xiao Bian will give you a brief introduction to the case of several smart cities, giving you a glimpse of the current status and future of smart city construction in foreign countries.

Songdo, South Korea

South Korea has been at the forefront of the application of new technology countries, the country has the world's fastest consumer Internet, and its culture is also very recognized for the application of new technologies. Therefore, it is not surprising that South Korea has become one of the first countries to try to build a smart city by tapping the potential of the Internet. In 2001, South Korea took the lead in building a high-tech city for people to live in the future: Songdo. In Songdo, a fully-connected power facility not only provides city managers with information about current electricity usage, but it also helps local residents control their electricity usage. Traffic information sensors are also pre-provisioned on the public roads in Songdo to provide specific information on traffic conditions for the urban transport department, and allow traffic managers to intelligently reset traffic lights to reduce the incidence of traffic jams and traffic accidents. At the same time, it can optimize the configuration of traffic flow and people flow. These ¡°smart roads¡± are connected to the central control room through the network and can play an early warning role before the earthquake.

Santander, Spain is a medium-sized town. In order to reduce air and noise pollution, the city of Santander has begun to seek help from technology and become one of the pilot cities for large-scale sensor configuration. By launching the "SmartSantander" project, the city has deployed about 10,000 electronic monitoring devices. Each device includes two radio transceivers to communicate with other devices, GPS and sensors to monitor urban CO2 emissions, noise, temperature, ambient light and even parking spaces in a particular area. Each monitoring device communicates in real time via the Internet so that drivers can find the next suitable parking lot via mobile app or smart signal.
Gloucester, United Kingdom

The most prominent feature of this small British town in the construction of smart cities is that it has fully utilized sensors and established a ¡°smart house¡± pilot.

In Gloucester, sensors are installed around the house, and the information returned allows the central computer to control a variety of home devices. The smart house is equipped with a monitoring and communication network centered on the computer terminal. The infrared and inductive cushions can be used to automatically monitor the movement of the elderly in the house. The room is equipped with medical equipment to measure heart rate and blood pressure for the elderly and automatically transmit the measurement results to the relevant doctor.

Dubuque

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

In cooperation with IBM, the City of Dubuque plans to use the Internet of Things technology to digitize and connect all the resources of the city, including water, electricity, oil, gas, transportation, public services, etc., through monitoring, analysis and integration of various data intelligence. Respond to the needs of the public and reduce the city's energy consumption and costs. The city took the lead in completing the data construction of hydropower resources, installing CNC hydropower meters for residents and shops in the city, not only recording resource usage, but also using low-flow sensor technology to prevent resource leakage. The data recorded by the instrument will be reflected in the comprehensive monitoring platform for analysis, integration and public display.

summary

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