The Internet of Things technology highly integrates and comprehensively applies the new generation of information network technology to realize the ideal of interconnectedness of all things and make the world a virtual reality. "Holistic" has become an important direction and driving force for a new round of industrial revolution. Because of Internet technology, all aspects of society have been significantly improved, and technology has a lot of application space. However, do you understand the five core technologies of the Internet of Things that permeate every aspect of our lives?
1. Radio Frequency Identification (RFID) Technology
Radio Frequency Identification (RFID) is to identify specific targets through radio signals and read and write them. Wireless communication technology for related data. This technology has many advantages, such as non-contact automatic identification, all-weather, strong identification ability, no contact wear, and the ability to automatically identify multiple items. To realize the ideal of "connecting the world", we can rely on radio frequency identification technology to track and share items around the world.
Nowadays, the RFID technology market is gradually mature and the cost of tags is low. However, since this technology generally does not have the function of data collection, it is mostly used for identification and attribute storage. In our country, the application fields of this technology are mainly in the fields of ID card recognition, electronic toll collection and logistics management.
2. Network communication technology
Network communication contains many technologies, among which 4G communication technology and 5G communication technology are very popular. wireless communication technology and M2M technology. Different technologies are used in different fields and play different roles.
In the field of control, the air conditioner 4G remote controller uses 4G communication technology to remotely complete the control process of the air conditioner. In wireless irrigation in smart agriculture, LORA wireless communication technology is used to complete automation. irrigation. In the field of intelligence, through M2M communication technology, intelligent, interactive and seamless connections between people, machines and systems are realized, enabling timely communication and operation between machines without human intervention.
3. GPS Technology
GPS technology is also called the Global Positioning System. A new generation satellite navigation and positioning system with all-round real-time three-dimensional navigation and positioning capabilities on land, sea and air. GPS technology can be combined with wireless communication technology to achieve global positioning, playing an important role in our logistics intelligence and intelligent transportation. It is reported that the earliest GPG satellite positioning system is about to reach its service age, and my country's Beidou satellite has begun to be used. Similarly, as a positioning system, one is about to be retired and the other has just started. Future development can be expected.
4. Computer Technology
In the Internet of Things, computer technology has been fully popularized and widely used. In the 20th century, computers As one of the most advanced scientific inventions, Internet of Things technology originated from computer technology. Computer technology has developed again based on the Internet of Things, making everything interconnected and providing many conveniences to society, and has been generally recognized. In smart agriculture, smart cities, weather station monitoring stations and other equipment, computer technology is used to detect data from sensors and then upload it to the environmental monitoring cloud platform.
5. Sensor technology
In the Internet of Things, computer technology is its brain, communication technology is its blood vessel, and GPS technology is Its cells, RFID technology are its eyes, and sensors are its nervous system. Sensors can sense all information from the outside world and transmit the sensed information to the brain.
Sensor technology is widely used in the intelligent field:
In the testing field: there are 86 LCD temperature and humidity transmitters, industrial-grade temperature and humidity transmitters transmitter, indoor temperature and humidity transmitter, waterproof housing temperature and humidity transmitter, etc.
In the field of smart agriculture: there are light carbon dioxide temperature and humidity sensors, wind speed and wind direction sensors, multi-functional blind boxes, etc.
In the field of wireless irrigation: there are soil pH transmitters, soil temperature and humidity transmitters, soil speed testers, etc.
The application field of Internet of Things technology is particularly broad, covering almost any industry. It is everywhere in environmental monitoring, logistics and transportation, commercial finance, and aerospace. Perhaps in the future, there will be more Powerful technology has surpassed it, but now, it still meets the strategic needs of the development of the times.
