The core and foundation of the Internet of Things is still the Internet, which is an extension and expansion network based on the Internet. Its client extends to any object and exchanges and communicates information, that is, object information. The Internet of Things digitizes the real world and is widely used. On the Internet of Things, everyone can connect real objects online with electronic tags, and their specific locations can be found on the Internet of Things.
Through the Internet of Things, machines, equipment and people can be centrally managed and controlled by a central computer, and household equipment and cars can also be remotely controlled, and they can also search for locations and prevent items from being stolen, similar to automatic control systems. At the same time, by collecting the data of these small things, it can finally be aggregated into big data, including re-designing roads to reduce major social changes such as car accidents, urban renewal, disaster prediction, crime prevention and epidemic control.
Functions of the Internet of Things:
Online monitoring: This is the most basic function of the Internet of Things. Generally, the Internet of Things is mainly based on centralized monitoring, supplemented by control. Location traceability: generally based on sensors, mobile terminals, industrial systems, building control systems, home intelligent facilities, video surveillance systems and other GPS (or other satellite positioning, such as Beidou) and wireless communication technologies, or only relying on wireless communication technologies, such as positioning based on mobile base stations, RTLS and other alarm linkage: mainly providing event alarm and prompt, and sometimes providing linkage function based on workflow or rule engine. Command and Scheduling: Command, scheduling and scheduling functions based on time scheduling and event response rules. Pre-plan management: dealing with events arising from events according to preset rules or regulations.
