What is Internet of Things? What does it have to do with our lives?

Recently, word "Internet of Things" has become popular, but many people do not know what Internet of Things is. Today I will introduce you to Internet of Things.

What is Internet of Things

The currently accepted definition of Internet of Things is: through radio frequency identification (RFID) devices, infrared sensors, GPS global positioning system, laser scanners and other information gathering equipment, according to an agreed upon agreement, any element connected to Internet Network that connects , exchange information and interact to realize intelligent identification, positioning, tracking, monitoring and control.

What is Internet of Things? What does it have to do with our lives?

In layman's terms, when each element can be uniquely identified, use technologies such as identification, communication, and computing to create a network that connects various elements based on Internet, which people often refer to as Internet of Things.

Internet of Things is a typical interdisciplinary subject, and its main technologies include IPV6 technology, cloud computing technology, sensor technology, RFID intelligent identification technology, wireless communication technology, etc. So, from a technical point of view, mainstreams of Internet of Things include: computer science and engineering, electronics and electrical engineering, electronic information and communications, automatic control, remote sensing and telemetry, precision instruments, e-commerce, etc. .

Internet of Things Applications

So, how does Internet of Things, which includes so much high technology, affect our lives?

Internet of Things applications mainly include electronic license plates and electronic toll collection (ETC) systems in smart transportation, smart grids, smart healthcare monitoring, smart cities, environmental protection, and smart agriculture.

What is Internet of Things? What does it have to do with our lives?

Electronic license plate

E-License Plate is an IoT application for smart vehicles. It is a new RF auto-identification technology with characteristics of high-speed identification, dismantling protection, magnetic field protection, encryption, storage, etc. The public security traffic management department can apply this technology. Accurately and comprehensively obtain traffic information, regulate vehicle use and driving behavior, keep vehicles from occupying lanes, changing lanes, speeding and other illegal activities, and can effectively deal with illegal vehicles. such as hit and run, cloning and related cases.

Smart Grid

In power generation channel, smart grid organizes sensor monitoring points for conventional units, tanks, and new energy wind turbines; online monitoring of vibration, temperature and wire slack, power line deflection from wind, power line image and video, tower tilt. and early warning, etc. make full use of sensor technology. The power distribution line also makes full use of various detection and identification technologies to monitor status of power distribution equipment, control operation of distribution network on site, and intelligently control.

Smart Health

In intelligent health care medical monitoring application, various sensors can be installed on medical guardian to monitor parameters of human health and transmit them to corresponding medical center in real time. The health center will remind you via mobile phone. Go to hospital for a medical examination to achieve real-time monitoring, intelligent analysis and automatic early warning.

Smart City

In smart city building safe city app, global eye monitoring probe deployed in streets and alleys is used to intelligently analyze image sensitivity and interact with 110, 119, 112, etc. Communication between people . sensors and alarms to create a harmonious and safe urban environment.

Environment Protection

In environmental protection applications, wireless sensing technology is used for environmental monitoring, population biological surveys, meteorological and geographic surveys, flood and fire detection. Such as tracking habitats of rare birds, animals and insects, monitoring water levels and related water resources and pollution information in various regions, layingka a large number of nodes to monitor fire danger inside forest area at any time, habitats - water quality, atmosphere, electromagnetic radiation, noise, precipitation, soil geology, natural disaster detection, etc.

Smart Farming

Smart agriculture will automatically organize various sensor nodes to form a sensor network, collect real-time information about farmland through various sensors, and provide timely feedback to farmers so that farmers can monitor status of farmland in monitoring area without leaving from home and without leaving home. information. In addition, farmers can also remotely control equipment through mobile phones or computers. The automatic control system reduces number of workers for irrigation and crop care, and improves production efficiency.

In fact, not only these aspects, food safety, library management, financial payments, smart home, etc. are gradually being included in IoT application map. It can be said that Internet of Things has gradually penetrated into all aspects of our lives. Due to blessing of AI, big data, etc., development of Internet of Things has also become more intelligent.
