-First, we should briefly introduce the concept of the Internet of Things, and then explain its constituent elements-
The Internet of Things is a huge social information system project composed of perception layer, transmission layer and processing layer, with a huge industrial chain, involving all walks of life, society and life of the national economy. Among them, the perception layer is mainly responsible for object identification and information collection, the transmission layer is responsible for network access and information transmission of various devices, and the processing layer is responsible for information analysis, processing and decision-making, so as to realize or complete specific intelligent applications and service tasks.
Since the focus of the paper is "construction", you have to think about it? Then why build it? How to build it?
-Let's talk about why we built it-
Personal opinion: This is a trend that reflects the society after the technology develops to a certain stage. The Internet has been fully popularized, and the fundamental technology of the Internet of Things is RFID. So why doesn't RFID say XOR sensor network of Internet of Things? In fact, if you look at the science and technology news, you will find that there are not many, but not many, which have not yet risen to this general trend. Then building the Internet of Things can be said to be a social trend, and it is also a global village in the concept of the Internet of Things. So you see, why didn't you mention it before, but now it is because RFID and the Internet have developed into a node, which conforms to the concept of global village, and the Internet of Things is booming ~ ~ (purely personal, please don't cross it).
-And then how to build-
Because there are many forms of architecture, I have chosen four general directions for you. Give different examples of industrial construction, which can be understood in detail.
I composition and function of enterprise internet of things enterprise internet of things has two parts: local area network internet of things and wide area network internet of things. The internal supervision that is beneficial to the enterprise's operation and development, such as automatic operation management of equipment, internal monitoring management of enterprises, and factory safety monitoring management, all belong to enterprise LAN IOT. With the help of LAN and Internet of Things, enterprise managers can effectively monitor the production and living conditions of enterprises through computers within a certain range, automatically receive abnormal accident alarms in real time, issue emergency instructions and take emergency control measures. For example, in order to reduce potential safety hazards and energy waste, programs such as three-minute unattended automatic alarm and flashing red indicator light are designed for a large equipment. Then, when the equipment runs unattended for more than three minutes, the monitoring computer will automatically give an alarm, and at the same time, the red light on the display screen will flash to remind managers to pay attention and take corresponding measures. For another example, there is an emergency stop button at the bottom of the monitoring interface of a large device. When we find through the monitor that the equipment is or will soon enter a dangerous operation (such as injury) state, we immediately click the emergency stop button on the screen to stop the equipment from running. For those non-automatic running equipment with simple and changeable operation and long running time, we can control the operation through remote centralized monitoring. In medical treatment, it can realize the centralized feedback of multiple physiological real-time information of patients and the remote control of medical care equipment. Wide-area Internet of Things is based on the local Internet of Things, which realizes the transmission and management of remote information through wired or wireless wide-area networks.
Two. Composition and Function of Social Internet of Things Social Internet of Things refers to a social security management network that takes community public areas, streets, public venues, public transport, large-scale trade markets and other public venues as units, and collects, manages and publishes information beneficial to the public interest such as forest fires, environmental pollution and air quality. For example, the escape route of criminal suspects, the escape trajectory of accident vehicles and the timely discovery of forest fire risks.
III. Composition and Function of Personal Networking Personal networking refers to a link system for exchanging personal services (such as tax payment, logistics, communication, savings, currency trading and operation state control of household appliances) and information about its operation process through a wide-area wireless network. For example, after the control means of household appliances are preset, the air conditioner can be turned on in real time under remote monitoring, rice can be washed automatically for cooking, or predetermined meals can be delivered to the dining table through the automatic safety entrance.
Four. The composition and function of the administrative Internet of Things refers to the real-time centralized supervision, review and processing of application forms such as office space, financial statements, personnel statements and quality inspection reports of subordinate departments and enterprises by administrative departments. Timely feedback information to the grassroots, issue instruction documents, and convey the spirit of superiors.
Finally, I wish the paper a success.
