The basic characteristics of the Internet of Things are from the perspective of communication objects and processes, and the information exchange between things and people is the core of the Internet of Things. The basic characteristics of the Internet of Things can be summarized as overall perception, reliable transmission, and intelligent processing.
Overall perception - Various types of information about objects can be perceived and obtained using sensing devices such as RFID, QR codes, and intelligent sensors.
Reliable transmission - By integrating the Internet and wireless networks, real-time and accurate information of objects is transmitted for information exchange and sharing.
Intelligent processing - Using various intelligent technologies to analyze and process the data and information perceived and transmitted, achieving intelligent monitoring and control. Based on the above characteristics of the Internet of Things and the perspective of information science, the functions of the Internet of Things in processing information can be summarized around the process of information flow:
(1) The function of obtaining information. It mainly refers to the perception and recognition of information, which refers to the perception and sensitivity to the state and changes of things' attributes; The recognition of information refers to the ability to express the perceived state of things in a certain way.
(2) The function of transmitting information. The main task is the process of transmitting, transmitting, and receiving information, which involves transferring the obtained state information and its changes from one point in time (or space) to another. This is commonly known as the communication process.
(3) The function of processing information. It refers to the process of processing information, using existing or perceived information to generate new information, which is actually the process of making decisions.
(4) The function of application information. The process of information ultimately exerting its utility, which has many forms of expression. More importantly, by adjusting the state and transformation of objects, the object is always in a pre designed state.
