How the Internet of Things is impacting people s lives

In a simple way, 4 minutes will allow you to thoroughly figure out what an IoT device is, what is the Internet of Things, and what is the use of the Internet of Things.

The Internet of Things has brought great changes to our lives, first of all, it can achieve precise management and control, for example, home intelligent devices can realize remote management of the family, and can control the family environment anytime and anywhere; Secondly, the Internet of Things can promote data analysis, and then realize learning and implementation, find problems in time, get twice the result with half the effort, and make life more convenient and efficient; Finally, the Internet of Things can also enable resource sharing, increase the utilization of related resources, reduce costs, and improve the quality of life. In short, the Internet of Things has brought great changes to our lives, making life more convenient and efficient.

With the touch of a button on your computer or mobile phone, you can see the condition of an item or a person's movements, even from thousands of miles away. Send a text message and you'll be able to turn on the fan; If someone trespasses into your home, you'll also receive an automatic alarm. Such an intelligent scene is no longer unique to Hollywood science fiction blockbusters, and the Internet of Things is approaching our lives step by step.

All of this is possible because there is a key technology in the "Internet of Things" called Radio Frequency Identification (RFID) to store information about objects. For example, embedded RFID-SIM card in the mobile phone, the "information sensing device" in the mobile phone can be connected to the mobile network, this mobile phone, not only can confirm the identity of the user, but also pay the fee, make an appointment to visit, realize the query and payment of mobile phone bills, water, electricity and gas bills, lottery betting, airline booking and other services.

It can be seen that the "Internet of Things" has a wide range of applications in personal health, smart grids, public transportation, etc. As long as a specific object is embedded in RF tags, sensors and other devices, after being connected to the Internet, a huge network system can be formed, and on this network, people can easily obtain and control the information of objects even if they are thousands of miles away.

The application of the Internet of Things is not just a concept, it has been used in many fields, but it has not been used on a large scale. Common use cases are:

1. The Internet of Things sensor products have been first applied in the anti-intrusion system of Shanghai Pudong International Airport. The airport anti-intrusion system has laid more than 30,000 sensing nodes, covering the ground, fences and low-altitude detection, which can prevent people from crossing over, smuggling, terrorist attacks and other offensive intrusions. Not long ago, the Shanghai World Expo also signed an order with the Wuxi Sensor Network Center to purchase 15 million yuan of anti-intrusion micro-nano sensor network products.

2. Zigbee street lamp control system lights up Jinan Garden Expo Park. The application of Zigbee wireless lamp lighting, energy-saving and environmental protection technology is a highlight of the Garden Expo. All functional lighting in the campus is controlled by Zigbee wireless technology.

3. Intelligent transportation system (ITS) is the use of modern information technology as the core, the use of advanced communication, computer, automatic control, sensor technology, to achieve real-time control and command management of traffic. Traffic information collection is considered to be the key subsystem of ITS, which is the basis for the development of ITS and the premise of transportation intelligence. Whether it is traffic control or traffic violation management system, it involves the collection of traffic dynamic information, and the collection of traffic dynamic information has become the primary task of traffic intelligence.

Some experts ** within 10 years the Internet of Things may be popularized on a large scale and develop into a trillion-scale high-tech market. At that time, the Internet of Things will play a role in almost all fields such as personal health, traffic control, environmental protection, public safety, safe home, intelligent fire protection, industrial monitoring, and elderly care. Some experts say that in just three to five years, the Internet of Things will fully enter people's lives and change people's lifestyles.

First of all, the Internet of Things will make life more convenient. The Internet of Things (IoT) makes it possible to "smart nannies", which can help us with tedious household chores, including purchasing, laundry, cleaning, etc., and can also protect the safety of the home through connected monitoring.

And voice technology can also realize human-computer interaction, so that the "smart nanny" becomes a "confidant companion Qing Li Hong", the elderly can talk to them, and the honor book can even tell their hearts and so on. At the same time, they are not only able to accompany the elderly emotionally, but also to monitor them in health care. The application of sensors and other technologies can not only monitor their heart rate, blood pressure and other physiological indicators, but also give instant alarms in case of emergencies such as falls. ”

The Internet of Things (IoT) is a new technology that implicitly refers to the interconnection between various sensors and the existing "Internet".

The technical idea of the Internet of Things is to "connect everything according to demand", with perception technology and network communication technology as the main means, to realize the ubiquitous connection of people, machines and things, and to provide infrastructure for information perception, information transmission, information processing and other services.

The origin of the Internet of Things refers to the real-time collection of any object or process that needs to be monitored, connected and interacted with through various devices and technologies such as information sensors, radio frequency identification technology, global positioning system, infrared sensors, laser scanners, etc., and collects various required information such as sound, light, heat, electricity, mechanics, chemistry, biology, location, etc., and realizes the ubiquitous connection between things and things, things and people, and realizes the intelligent perception, identification and management of items and processes. The Internet of Things is an information carrier based on the Internet, traditional telecommunication networks, etc., which allows all ordinary physical objects that can be independently addressed to form an interconnected network.

The Internet of Things is connected with the built-in smart chip of the object through the Internet, which becomes the Internet of Things. For example, if you are about to go home and the weather is very hot, you can turn on the air conditioner through your mobile phone and feel cool as soon as you get home, so as to achieve the purpose of smart life.
