Industrial Internet of Things is the continuous integration of various acquisition and control sensors or controllers with perception and monitoring capabilities, as well as mobile communications, intelligent analysis and other technologies into all aspects of the industrial production process, thereby greatly improving manufacturing efficiency, improving product quality, and reducing products. Cost and resource consumption will eventually achieve a new stage of upgrading traditional industries to intelligence.

technical problem

The research of industrial Internet of Things technology is an interdisciplinary project, which involves the fields of automation, communication, computer and management science. The wide application of the Industrial Internet of Things needs to solve many key technical problems.

Sensor Technology

Inexpensive sensors with good performance are the cornerstones of industrial Internet of Things applications. The development of industrial Internet of Things requires more accurate, smarter, more efficient and more compatible sensor technologies. Intelligent data acquisition technology is a new direction in the development of sensor technology.The ubiquity of information puts forward higher requirements on industrial sensors and sensing devices.Specifically, miniaturization: the miniaturization of components requires saving resources and energy; intelligence: with artificial intelligence technologies such as self-calibration, self-diagnosis, self-learning, self-decision, self-adaptation and self-organization; low power consumption and energy Obtaining technology: The power supply is battery, sunlight, wind, temperature, vibration and other methods.

Device compatible technology

In most cases, companies will build the Industrial Internet of Things based on existing industrial systems. How to realize that the sensors used in the Industrial Internet of Things can be compatible with the sensors already used in the original equipment is one of the problems facing the promotion of the Industrial Internet of Things.

The compatibility of the sensor mainly refers to the compatibility of the data format and the compatibility of the communication protocol. The key to the compatibility is the unification of the standards. At present, protocols such as Profibus and Modbus commonly used in industrial fieldbus networks have solved compatibility problems. Most industrial equipment manufacturers have developed various sensors and controllers based on these protocols.At present, protocols such as Profibus and Modbus commonly used in industrial fieldbus networks have solved compatibility problems. Most industrial equipment manufacturers have developed various sensors and controllers based on these protocols. In recent years, as industrial wireless sensor network applications have become more and more common, the current industrial wireless Wireless HART, ISA100.11a and wIA-PA3 major standards are compatible with IEEE802.15. 4 wireless network protocols, and provide a tunnel transmission mechanism to be compatible with existing The communication protocol enriches the composition and functions of the industrial Internet of Things system.

Industrial safety production management

"Safety production" is the top priority in modern industry.Industrial Internet of Things technology can monitor the safety status information of operators, equipment, machinery and surrounding environment in real time by installing sensors in dangerous operating environments such as mining equipment, oil and gas pipelines, and mining equipment, and obtain all-round safety elements in the production environment. , To upgrade the existing network supervision platform to a systematic, open and diversified comprehensive network supervision platform, effectively guaranteeing the safety of industrial production.
