The Internet of Things (IoT) originated in the media field and is the third revolution in the information technology industry.
The Internet of Things technology refers to the collection, transmission, and control of information between things and things and between people and things based on information content sensing devices. What are the main technologies of the Internet of Things?
In the Internet of Things, computer technology is its brain, communication technology is its blood vessels, GPS technology is its cells, RFID technology is 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.
Radio Frequency Identification (RFID) Technology
Radio Frequency Identification (RFID) is a wireless communication technology that uses radio signals to identify specific targets and read and write related data. This technology has many advantages, such as non-contact automatic identification, all-weather, strong identification ability, non-contact wear, and automatic identification of multiple items. Achieving the ideal of "word association" can rely on radio frequency identification technology to track and share information on items around the world. RFID has broad application prospects in automatic identification and item logistics management.
Embedded System Technology
Embedded system technology: It is a complex technology that integrates computer software and hardware, sensor technology, integrated circuit technology, and electronic application technology. It makes traditional electromechanical products intelligent, has various functions such as fault diagnosis, automatic alarm, information transmission, remote control, etc., and realizes the informatization and intelligence of product use and management. Because of the small size, strong function, and low cost of embedded systems, they are widely used in smart homes, the Internet of Vehicles, and other fields.
Network communication technology
The radio communication technology applied in the Internet of Things is divided into two categories: short-range communication technology and wide-area network communication technology. Scenarios; WAN communication technologies mainly include LoRa, NB-IoT, 4G, and other technologies, which are suitable for scenarios with a wide area, large data volume, many connected devices, and remote use areas.
By implanting intelligent systems in objects, objects can have certain intelligence and can communicate with users actively or passively, which is also one of the key technologies of the Internet of Things.
Nanotechnology: It is to study the properties and applications of materials with a structure size in the range of 0.1 to 100 nm, mainly including nanosystem physics, nanochemistry, nanomaterials, nanobiology, nanoelectronics, nanofabrication, nanomechanics, etc.
GPS technology, also known as Global Positioning System, is a new generation of satellite navigation and positioning system with real-time three-dimensional navigation and positioning capabilities of sea, land, and air. GPS technology can be combined with wireless communication technology to achieve global positioning, which plays an important role in intelligent logistics and intelligent transportation. It is reported that the service age of the earliest GPG satellite positioning system is about to arrive, and my country's Beidou satellite has begun to be used. Also as a positioning system, one is about to be retired, the other is just starting, and future development can be expected.
In the Internet of Things, computer technology has been fully popularized and widely used. In the 20th century, computer technology was one of the most advanced scientific inventions. The Internet of Things technology originated from computer technology, and computer technology developed again relying on the Internet of Things. It makes everything interconnected and provides a lot of convenience for society, which has been generally recognized. In smart agriculture, smart city, weather station monitoring stations, and other equipment, computer technology is used to upload sensor detection data to the environmental monitoring cloud platform.
The application field of Internet of Things technology is particularly extensive, covering almost any industry. It is widely used in environmental monitoring, logistics and transportation, commercial finance, and aerospace. Perhaps in the future, there will be more powerful technologies. Beyond it, but now, it still meets the strategic needs of the development of the times.
