What Is the Internet of Things Technology?
- By:Iris Liang
The Internet of Things technology is: through radio frequency identification (RFID), infrared sensors, global positioning systems, laser scanners and other information sensing equipment, according to the agreed agreement, any item is connected to the Internet for information exchange and communication to achieve A network technology for intelligent identification, positioning, tracking, monitoring and management.
What is the Internet of Things technology?
The core and foundation of "Internet of Things technology" is still "Internet technology", which is a kind of network technology that is extended and expanded on the basis of Internet technology. communication.
There are three key technologies in IoT applications.
1. Sensor technology, which is also a key technology in computer applications. As everyone knows, most computers deal with digital signals so far. Since there are computers, sensors have been needed to convert analog signals into digital signals for computers to process.
2. RFID tag is also a kind of sensor technology. RFID technology is a comprehensive technology integrating radio frequency technology and embedded technology. RFID has broad application prospects in automatic identification and item logistics management.
3. Embedded system technology: it is a complex technology that integrates computer software and hardware, sensor technology, integrated circuit technology, and electronic application technology. After decades of evolution, smart terminal products featuring embedded systems can be seen everywhere; from MP3 around people to satellite systems for aerospace and aviation. Embedded systems are changing people's lives and promoting the development of industrial production and the defense industry. If the Internet of Things is used as a simple analogy with the human body, sensors are equivalent to human senses such as eyes, nose, and skin. The network is the nervous system to transmit information, and the embedded system is the human brain. After receiving the information, it must be classified. deal with. This example vividly describes the position and role of sensors and embedded systems in the Internet of Things.
Application of IoT technology
The Internet of Things is an extension of the Internet and an important part of a new generation of information technology. The Internet of Things realizes the interconnection of objects and objects, and the interconnection of objects and people. It has the characteristics of comprehensive perception, reliable transmission, and intelligent processing. It enables humans to manage production and life in a more refined and dynamic way, thereby improving the informatization capabilities of the entire society.
The Internet of Things generally refers to the interconnection network and applications between things. It is widely used in transportation, logistics, security, electricity, home and other fields. It is divided into three parts: perception layer, network layer and application layer. The perception layer mainly includes various Perception devices and terminal equipment. Perception devices include RFID tags, QR codes, various sensors, cameras, etc. The network layer is divided into two parts: access and transmission, and the application layer includes various application service platforms. More mature application areas include smart logistics, smart transportation, smart grid, security monitoring, smart card systems, etc.
Characteristics of IoT technology
Internet of Things technology has the characteristics of identification and communication
Although the Internet of Things is established on the basis of the Internet, it is still very different from the Internet. The objects of the Internet of Things are objects. The composition of the Internet of Things includes different types of sensors. The information collected by different types of sensors The format and content will also vary, and the collected information is real-time, which requires timely updates to the collected information.
The Internet of Things technology has the characteristics of intelligence
The ultimate goal of the implementation of the Internet of Things is to automatically control related equipment through an intelligent platform. The Internet of Things is a combination of sensors and intelligent information processing technology, through the calculation of the collected information, and then using various key technologies. Relevant management and operation are controlled to meet the different needs of different users. These controls are not restricted by time and region, so that the purpose of users' intelligent operation is achieved.
Internet of Things technology has the characteristics of the Internet
The use of the Internet is achieved through various protocols between networks. The information collected by the sensor is transmitted through the Internet. To ensure the quality of information transmission, various Internet protocols need to be well supported.
Application of IoT technology
The application fields of the Internet of Things technology are very wide, involving government offices, medical care, food, military, transportation, agriculture, forestry, smart grid, and logistics, etc., and have played a pivotal role in these aspects.
Application of Internet of Things Technology in Industrial Production
The application of the Internet of Things in transportation is mainly manifested in monitoring production data and operating procedures. When there is an abnormality or error code in the data, the technical teams of both parties can intervene in the production line as soon as possible to avoid losses or safety accidents. Hangao Tech (SEKO Machinery) is the first manufacturer to apply IoT technology to stainless steel industrial pipe producing machine line tube making machine. The promotion and popularization of this technology helps our customers to more effectively control equipment maintenance costs and obtain more efficient after-sales service.
Application of Internet of Things technology in logistics transportation, management and distribution
The Internet of Things technology will play a very good role in the process of logistics transportation, logistics storage, and logistics distribution. In the process of logistics and transportation, the Internet of Things technology combines global positioning technology, geographic information technology, sensor network technology, mobile communication technology, etc.
First, global positioning system, geographic information system sensors, and mobile communication equipment are installed in transportation vehicles. In this way, marketers and users can accurately understand the location of the vehicle. It is also necessary to install sensors in the carriages of the goods. Using sensor network technology, marketers can accurately understand the temperature and humidity of the goods.
The quality of items can also be monitored. This ensures the quality of the goods being transported. For example, when the temperature and humidity in the transport truck decrease or increase, the sensor will transmit the information to the marketer in time through wireless information technology, and the marketer will respond to the vehicle after receiving the information.
The temperature and humidity inside are controlled. In the process of storing items, it is possible to store items with containerized properties through the Internet of Things technology, radio frequency technology and bar code technology. Paste barcodes in the items, and add electronic labels to the item trays, and put the same variety and the same number of items on the trays. When the entire tray is in and out of the warehouse, the reader will read multiple trays, which speeds up the product. The speed of entering and leaving the warehouse. When a pallet is not full, barcode technology is used to scan the item.
In the process of goods transportation, the traffic guidance system will be used to understand traffic information. The traffic guidance system is a product of the combination of traffic control system, Internet of Things technology, and information technology. It enables vehicles to establish contact with the traffic system and exchange information with customer terminals through wireless networks.The driver can understand the road information in time, and the traffic system can make the best driving route for the user, so that the goods can be delivered to the customer in time.
