Mobile IoT is a kind of network technology built on the basis of Internet, communication network and wireless LAN in order to realize the mutual transmission of data and data, which is mainly divided into three layers, as follows:
1. Application layer: The application layer is the channel connecting the two between mobile IoT and the physical world, which needs to be combined with multi-domain industries and used to realize the intelligent application of mobile IoT technology in the real world. Usually, the lower end of the mobile IoT application layer is divided into two sub-levels
Application layer, which is generally used for data and information processing in various fields, covering mainly mobile medical, mobile device communication, e-banking, traffic monitoring, etc.
Terminal equipment layer, this level covers a variety of mobile terminals, can realize the direct dialogue between the system operator and the device, and will be accepted in the application guide after analysis of the information data, effective processing, and finally sent to the human brain
2. Network layer: The network layer of mobile Internet of things covers multiple systems and technology platforms, for example, wireless communication, wired communication and other network technologies, its main function is to be able to sense the data information on the system guide through a variety of network transmission means to the server, in general, the network used for data transmission is mainly divided into local area network, 3G mobile network and enterprise intranet, etc.
3. Perception layer: Mobile IoT perception layer is the main place for information collection and identification, sensors are the key core technology, but also has RFID tags, two-dimensional code, reader, sensor and other equipment
The working principle of mobile IoT
The essence of IoT technology is a fusion network system based on wireless Internet, using sensors, RFID radio frequency identification technology, wireless data communication, GPS and other technologies, whose main function is to achieve information interconnection and sharing. In the whole system, all items are able to interact with each other and are not interfered by other factors
Generally speaking, the working principle of mobile IoT can be roughly divided into three parts, which are attribute identification, attribute reading and information processing in order
1. Attribute identification: the identification of object information attributes, generally divided into dynamic and static attributes. Static attributes can be directly stored in the RFID tag, while dynamic object attributes need to be monitored through sensor technology in order to store them
2. Attribute reading: read the object attributes through professional identification equipment, and convert the relevant information in the object into a form that can be transmitted to the network
3. Information processing: Information processing is a relatively late step in the work of the mobile Internet of Things, the object information that has completed the form of conversion is transmitted to the information processing system, the system to carry out real-time calculations of its information, the form of calculation is generally divided into two kinds of centralized computing and distributed computing
