2. Equipment compatibility technology: In most cases, enterprises will build industrial Internet of Things based on existing industrial systems. How to realize the compatibility of sensors used in industrial Internet of things with the sensors already used in existing equipment is the Industrial Internet of Things Promotion Office. One of the problems faced. The compatibility of the sensor mainly refers to the compatibility of the data format and the compatibility of the communication protocol. The key to compatibility is the unification of the standard. At present, the Profibus and Modus protocols commonly used in industrial fieldbus networks have solved the compatibility problem well. Most industrial equipment manufacturers have developed various types of sensors and controllers based on these protocols. In recent years, with the increasing popularity of industrial wireless sensor network applications, the current industrial wireless WirelessHART, ISA100.11a and wIA-PA3 standards are compatible with the IEEE802.15.4 wireless network protocol, and provide a tunnel transmission mechanism compatible with existing The communication protocol enriches the composition and functions of the industrial IoT system.
3. Network technology: The network is one of the core components of the industrial Internet of Things. Data is transmitted through the network between different levels of the system. The network is divided into wired network and wireless network. The wired network is generally applied to the cluster server of the data processing center, the local area network of the factory and part of the field bus control network, and can provide a high-speed and high-bandwidth data transmission channel. Industrial wireless sensor network is an emerging technology that uses wireless technology for sensor networking and data transmission. The application of wireless network technology can greatly reduce the wiring cost of industrial sensors, which is conducive to the expansion of sensor functions, thus attracting domestic and foreign The attention of many companies and research institutions.
The traditional wired network technology is relatively mature, and has been verified by many applications. However, when wireless network technology is applied to industrial environments, it will face the following problems: strong electromagnetic interference in the industrial field, open wireless environment makes industrial machines more vulnerable to attack threats, and some control data needs to be transmitted in real time. Compared with wired networks, industrial wireless sensor network technology is in the development stage. It solves the shortcomings of traditional wireless network technology used in industrial field environments, providing high reliability, high real-time and high security. The main technology Including: adaptive frequency hopping, reliable communication resource scheduling, wireless routing, low overhead high precision time synchronization, network layered data encryption, network anomaly monitoring and alarm, and device network access authentication.
4. Information processing technology: Industrial information has exploded. The large amount of data generated in industrial production is a challenge for industrial Internet of Things. How to effectively process, analyze, record and refine the guidance for industrial production. The result is the core of the Industrial Internet of Things, and it is also difficult.
At present, there are many big data processing technologies in the industry. For example, SAP's BW system solves the problems brought by big data to the production and operation of enterprises to a certain extent. The development of data fusion and data mining technologies has also made massive information processing more intelligent and efficient. The ubiquitous perception of industrial Internet of Things makes people become the object of perception. Through the analysis of environmental data and the modeling of user behavior, one person, one machine and one machine in the process of production design, manufacturing and management can be realized. Behavioral, environmental, and state perceptions between machines more realistically reflect changes in detail in industrial production processes in order to produce more accurate analysis results.
5. Security technology: Industrial IoT security mainly involves data collection security, network transmission security and other processes. Information security plays a key role in enterprise operations. For example, in the metallurgy, coal, petroleum and other industries, data collection requires long-term continuous operation. How to ensure the accuracy of information during data collection and transmission is the premise of industrial IoT application in actual production.
