Whether internet or internet of things are an indispensable part of life, how to apply internet of things technology to industrial automation and production and life is a big test we face because the internet of things can not only realize the total energy saving and emission reduction in our country Goals, but also to change and improve the production management mode, so we only break this challenge to the Internet of things technology, high-quality, high-efficiency applications to the field of industrial automation.
First, the Internet of things in the industrial automation for the key technologies
Internet of Things in the process of industrial automation involved in the three main layers of technology, one is the perception of information, identification and positioning, the second is the network access and data and signal processing, the third is the industry application and so on. Among them, the perception, identification and location of information are the basic layers in the process of development and application of Internet of Things. In this process, RFID technology, sensor technology and control technology play a major role in this process. This layer The main technology. The network access and data and signal processing, mainly rely on the existing communications and wireless networks to achieve the development and application of this technology, and through a variety of devices and communications network connection to receive the data uploaded To the Internet, in order to achieve the network data transmission process, and in the process of transmission of data, storage of data, network information management technology is the main technology at this level. The third point is that IoT technology can provide more users with more rich, better and more efficient services after it has been processed by the above two technologies. In this process, the data uploaded to the Internet is processed Layers of the main technology.
1. Internet of things identification technology
All things that are exchanged in the Internet of Things have a unique, globally unique identification code, which in turn may be its unique identification code within a certain range, which may be permanent Sex-specific, may be temporary specific, it is also possible in a matter of the body there are several different identification code, the code of these different things, there may be an ID, it may be an IP, and in the Internet of Things Technically, in the process of object exchange, there must be a fixed device to identify these different identification codes. In some cases, an object may be composed of many different small objects. This requires that a large device be installed on the large object itself to identify the codes of these small objects. The device needs to establish a framework for sharing data rules with the Internet Device.
2. IoT architecture technology
The so-called IoT architecture technology is actually a kind of interoperable relationship reached between the providers and demanders of services in heterogeneous information systems. There are many ways to achieve this relationship One of the most direct and effective methods is to establish a shared model of resources, information and data between the two. In this sharing model, the service providers and demanders However, this sharing of resources is a non-lingual sharing, in order to ensure a more open space between service providers and demanders. The key to our design of the Internet of Things is that we Said "things" and their environment must be scalable, modular, scalable, and interoperable features.
3. Internet of Things data and signal processing technology
In any area of ​​production, IoT's data and signal processing technologies are integrated into the production process and sales process. In the IoT era for industrial automation, automation of production and sales, and analysis and output of all data through the network platform, etc., we still have to follow the semantic interoperability on the issues of data and signal processing in the Internet of Things Through the identification of intelligent devices and application of information technology to promote the application of the standard information technology to process all the data and information analysis and so on.
4. Internet of Things technology for industrial automation problems
Our research shows that IoT technology faces some of these technical challenges in the application of industrial automation. One of the most critical technical problems is to study the new sensors and sensing devices when it has a higher demand for it, the sensor technology and hardware systems for further miniaturization and intelligence, so as to energy acquisition Technology is handled more closely. Then there is the industrial wireless network technology, the Internet of Things technology for industrial automation applications, the most crucial technology is industrial wireless network technology, which includes communication technology, networking technology, network infrastructure services and network management and planning Technology, it is mainly through the transfer of information, information processing and application of information technology to achieve.
Second, the Internet of Things technology in industrial automation applications
IOT technology in our continuous development has been applied to all sectors of our production process and manufacturing industry, industrial restructuring, and constantly promote the various industrial enterprises in energy-saving emission reduction, improve production efficiency and improve product quality, Safety production, improve production and economic efficiency and so play an obvious role. Therefore, the application prospect of IOT technology in China's industrial automation is extremely broad, and the application technology in this aspect has become a hot technology in the application field.
1. Internet of Things technology industry application direction
Based on the existing integration of human society and various applications, it is further expanded in the fields of space and time and application through the communication and integration of things in the new dimension. This is another expression we call today the Internet of Things. Networking technology is a very systematic and broad-ranging technology. Its industrial application not only solves the problems of wired and wireless networks, but also solves the problems of application systems.
2. IoT technology in the field of energy saving and emission reduction
Now the Internet of things technology has been widely used in electric power, chemical and other high energy consumption, high pollution industries, and in the process of application effectively played the role of energy-saving emission reduction. In these industries through the application of IoT technology, using one of the sensing device to monitor it, and for the production process of electricity consumption monitoring and control, which effectively played the role of energy-saving emission reduction. In addition, they also set up an automatic pollution source monitoring system through IoT technology to monitor and monitor real-time monitoring of pollutant emissions from industrial processes and provide an important data basis for optimizing purification systems.
3. Internet of Things technology in the field of product information applications
The so-called product informationization means that the product information management, through the information to understand the product, promote the product
