Anonymous users2024-02-06Through perception and recognition technology, allowing objects to "speak and release information" is an important part of the integration of the physical world and the information world, and is the most unique part of the Internet of Things that distinguishes it from other networks. The "tentacles" of the Internet of Things are a large number of information-generating devices located in the perception and recognition layer, including RFID, sensor network, positioning system, etc. In the book "Introduction to the Internet of Things", the author believes that the data perceived by the sensor network is one of the important information of the Internet of Things.
Moreover, the China Internet of Things School-Enterprise Alliance believes that the rapid development of sensor networks is of great significance for the progress in the field of Internet of Things and the realization of the Internet of Things.
Since August 2009, Premier Wen put forward the "perception of China", the Internet of Things has been officially listed as one of the country's five emerging strategic industries, written into the "first work report", the Internet of Things in China has received great attention from the whole society, and its degree of attention is incomparable in the United States, the European Union, and other countries.
There are many people to expand the meaning of the sensor network to include the Internet of Things, there is some truth in this statement, Premier Wen's speech "Sense China" began with the focus on the sensor network, but at present, people tend to use the word Internet of Things (see the index chart on the right), the scope of the Internet of Things is greater than the sensor network, so in many occasions there is a "Internet of Things (sensor network)" mention, and this seems to have become the "official" mention.
As you can see from the graph, IoT and M2M are used more frequently than sensor networks, and the Google Trends chart in English shows the same results. This is probably the reason why the Internet of Things, not the sensor network, is written into the **work report.
In the book "Internet of Things: Technologies, Applications, Standards and Business Models", the author lists the sensor network as one of the four major technologies and applications of the Internet of Things, which has been recognized by some people in the industry.

Anonymous users2024-02-05The three basic characteristics of the Internet of Things: comprehensive perception, reliable transmission, and intelligent processing.
Reliable transmission: Through the integration of various telecommunication networks and the Internet, the received perception information is transmitted remotely in real time, so as to realize the interaction and sharing of information, and carry out various effective processing.
Intelligent processing: Using various intelligent computing technologies such as cloud computing and fuzzy recognition, it analyzes and processes massive data and information received across regions, industries and departments at any time.

Anonymous users2024-02-021. Sexual maintenance.
**Sexual maintenance**Sexual maintenance has always been one of the most significant roles of the industrial Internet of Things, using sensors to monitor the temperature, vibration, power consumption and other data of each part of the machine, users can find the abnormality of the equipment at any time, and maintain the shutdown time in advance to avoid unexpected downtime affecting production. Even users can build the corresponding scene through the built-in **or self-uploaded** through the simulation scene function, display the collected data in the corresponding position in the scene, and monitor the equipment status at any time through the changes in the data and ** in the scene.
2. Automatically control the data collected by general sensors.
The data collected by the automatic control general sensor often needs to be displayed on the computer or man-machine interface, and the staff manually controls the start-stop or lifting power of the equipment after observing the data status. Through the logic control function of the Yiyun system, the logic can be directly set up between the equipment and the equipment to be controlled, and the operation status of the equipment can be automatically adjusted according to data changes through PLC or other control methods, reducing time waste.
3. Dig out the connotation of data.
Dig into the data. The data collected by the sensor and the data after the feedback from the equipment are finally analyzed and studied, and become beneficial information for the enterprise, which provides decision-making support for the enterprise. For example, the analysis of the monitoring and limb measurement data on the product side can find the weakness or failure of the machinery, and strengthen it in order to improve the process and improve the product quality and competitiveness.

Anonymous users2024-02-01A sensor network is defined as a randomly distributed network of tiny nodes integrating sensors, data processing units, and communication units in a self-organizing manner.
Internet of Things: Through the SIM card, sensor, etc. installed on various objects, it is connected to the wireless network through the interface to give intelligence to the object, and can realize the communication and dialogue between people and objects and between objects.
For details, go to the mobile M2M portal** to see the specific application examples to clearly understand!

Anonymous users2024-01-31Personally, I feel that the sensor network is only a part or an aspect of the Internet of Things. The Internet of Things is a newly proposed concept that encompasses a wide range of things, and the Internet of Things is an industry, not a technology.
1. Industrial IoT devices are manufactured based on the industrial environment and have higher requirements than consumer IoT devices. >>>More
The Internet of Things refers to the real-time collection of any object or process that needs to be monitored, connected and interacted with through various devices and technologies such as various information sensors, radio frequency identification technology, global positioning systems, infrared sensors, laser scanners, etc. >>>More

A recruit went out to study, and the train happened to be on the way from his home, and he passed ** 1 hour early on the train and made an appointment to meet at the train station. Recruits enlist in the army for training is a very bitter thing, people are always tired of homesickness will be stronger, three years of obligation to be a soldier, three years to see relatives almost no chance, by their own experience is more than half a year to see relatives, learning opportunities passing by the door is a once-in-a-lifetime opportunity, how can you miss it? The young man was tormented for him in an hour, every minute and every second, and his heart had already flown to the arms of his relatives, while people were pacing up and down the train. >>>More
In a simple way, 4 minutes will allow you to thoroughly figure out what an IoT device is, what is the Internet of Things, and what is the use of the Internet of Things.
