Functions of Internet of Things Message Transfer Protocol

Technical Characteristics of Internet of Things

1. The basic characteristics of the Internet of Things are as follows: Fully aware of the information collection and acquisition of objects anytime and anywhere by means of radio frequency identification (RFID), sensors, locators and two-dimensional codes.

2. The basic characteristics of the Internet of Things: comprehensive perception, that is, using RFID, sensors, QR codes, etc. Get item information anytime, anywhere. There are many methods of data collection, which are multi-point, multi-dimensional and networked.

3. Compared with the traditional Internet, the Internet of Things has its distinctive features: the Internet of Things is a wide application of various sensing technologies. A large number of different types of sensors are deployed on the Internet of Things. Each sensor is an information source, and the content and format of information captured by different types of sensors are different.

4. It has the important characteristics of common object equipment, autonomous terminal interconnection and universal service intelligence. The Internet of Things is a complex and diverse integrated network system. According to the process of information generation, transmission, processing and application, the Internet of Things can be divided into perception and recognition layer, network construction layer, management service layer and comprehensive application layer.

5. The characteristics of the Internet of Things are as follows: From the communication object and process, the information interaction between things is the core of the Internet of Things. The basic characteristics of the Internet of Things can be summarized as holistic perception, reliable transmission and intelligent processing.

6. The basic characteristics of the Internet of Things are universality, real-time, interoperability, autonomy, intelligence and security. Universal Internet of Things connects all kinds of physical devices, sensors and intelligent devices to realize information sharing and interaction between things.

What functions does the Internet of Things Gateway have?

1. Therefore, this gateway has the key talent similar to API gateway, that is, it can access and adapt different types of protocols provided by various sensing devices at the sensing layer, and after protocol access, it can be converted into standard interface protocols and interact with the communication layer.

2. Hongqiao Internet of Things Gateway has multiple protocol conversion functions to provide efficient data transmission.

3. Manageability Strong management ability is very important for any large network. First of all, we should manage the gateway well, such as registration management, authority management, state supervision and so on.

4. Internet of Things gateway can realize protocol conversion between sensor networks and communication networks and between different types of sensor networks; Both wide area interconnection and local area interconnection can be realized.

5. A gateway is a device that uses different protocols to connect two network segments. The function of the gateway is to translate and convert data using different transmission protocols in two network segments.

6. The Internet of Things gateway mainly completes three tasks: one is to collect the data of sensor nodes; Secondly, data protocol conversion is carried out; Finally, the data after protocol conversion is sent to the public network quickly and effectively. In addition, the Internet of Things gateway also has corresponding management and control capabilities.

Key technologies of internet of things

1. The key technologies of the Internet of Things include sensor technology, network technology, cloud computing technology, artificial intelligence technology and security technology. Sensor technology: The core of the Internet of Things is to collect all kinds of data through sensors, so as to realize the Internet of Everything. Sensor technology includes measurement and detection technology, communication technology, data acquisition and processing technology.

2. The key technologies of the Internet of Things include: RFID technology; Sensor technology; Wireless network technology; Artificial intelligence technology; Cloud computing technology. Among them, RFID technology is the key technology in the Internet of Things, and RFID tags have standardized and interoperable information.

3. The Internet of Things is a collection, and technologies such as various sensors (such as radio frequency identification), various wireless sensor networks and intelligent linkage are the foundation of the Internet of Things. Sensor technology, computer technology and communication technology are also called the three major technologies of information technology.

4. Key technologies of the Internet of Things: 1) and radio frequency identification technology: Radio frequency identification, commonly known as "electronic tag", is the main source of information collection in the Internet of Things. Attaching an electronic tag to a target item can track and identify it on a global scale.
