Smart City Sensor Solutions
Sensors, as the "bridge" of smart cities, are indispensable in the construction of smart cities.
Smart city internet of things
The centralized application of the Internet of Things in the smart city makes the technology of the Internet of Things better. It is a larger demonstration project composed of N functional units of the Internet of Things. It carries and contains almost all related technologies such as the Internet of Things and cloud computing. It is the constituent element and basic unit of perceiving China.
Smart cities can be combined horizontally and vertically according to the size of the city and different needs to form a smart city system with system size, function emphasis, and key points.
A smart city cannot be achieved overnight, any one is an open system, which can continuously add functions, gradually improve and continuously upgrade the process.
A "smart city" needs to have four characteristics: comprehensive and thorough perception, broadband ubiquitous interconnection, smart fusion applications, and people-oriented sustainable innovation.
The first is to have a comprehensive and thorough perception: through sensing technology, to achieve monitoring and comprehensive perception of all aspects of urban management. Real-time intelligent recognition, three-dimensional perception of all-round changes in urban environment, status, location and other information.
Of course, it is also the inevitable result of the development of sensor applications!
Application of Sensors in Smart City Construction
The basic requirement of a smart city is that everything in the city is connected, and every 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.
1. Smart parking improves traffic efficiency
Traffic congestion is the number one problem facing modern cities, and as cars search for parking spaces on city streets, they increase emissions of carbon dioxide and other exhaust gases, which in turn affects urban air quality.
Smart parking technology promises to change that. The technology can provide real-time parking maps and parking space information to nearby car owners through the GPS data of smartphones and sensors embedded in the parking space, making the parking process more efficient and environmentally friendly.
2. Smart street lights make cities safer
Street lights are an important infrastructure of a city. Through the Internet of Things technology, street lights can become an important part of smart cities. Through street light sensors, real-time information on urban streets can be collected and analyzed, and real-time data on urban operations can be provided to managers, making urban management safer and more efficient.
Smart street lights can improve the safety of city streets and save governments a lot of electricity bills. Use energy-saving LED bulbs to replace old street lights, and through a wireless connection, when passers-by approach, the motion sensor of the bulb will be activated to provide illumination for passers-by, and when passers-by leave, it will automatically turn off. And when the bulb needs to be replaced, a reminder is sent to the management through the sensor.
3. Intelligent transportation improves traffic safety
Intelligent transportation systems include everything from self-driving cars to smart traffic signals. Through sensor analysis and communication between systems, intelligent transportation systems aim to "relieve congestion, improve traffic management, minimize environmental impact, and benefit commercial users and public transportation."
Cities around the world are using sensors linked to traffic lights and surveillance cameras to improve pedestrian safety. For example, at intersections, data collection technology is used to collect and analyze various traffic data through cameras, LED street lights, and sensors, so as to adjust road design and signal light time to improve pedestrian safety.
4. Smart energy changes the urban environment
Modernizing the grid with smart grid enhancements "is an integral step towards smart cities. The use of renewable energy sources such as rooftop solar can help bring about "sustainable change" that improves the environment and safeguards public health.
In the future, cities will realize zero-emission transportation, and in an emergency, electric vehicles that act as electric energy storage devices can provide cities with emergency electricity.
Smart grids also allow residents to access their energy data and enable utilities to offer new pricing plans that improve energy efficiency.
5. Intelligent management of resident medical care
Through the Internet of Things, smart cities can realize the possibility of connecting everything. People, buildings, transportation, and the environment will all be included in the entire data network, thereby improving urban services. At the same time, this connectivity, in turn, can help improve the health of residents.
6. Smart cities need smart environments
As smart "green" buildings increase in cities, cities need to consider how they can use new technologies to improve the environment more broadly.
Sensors Converge is known as the largest and most professional sensor and test and measurement exhibition in North America, and it is also one of the most influential industrial exhibitions in the world. It has a history of more than 30 years.
