The Internet of Things is integrating into the industrial automation system

In the field of industrial automation, with the transfer of applications and services to cloud computing, the main models of data and computing locations have been changed, which has also brought disruptive changes to the field of embedded devices.

The proposal of the Internet of Things provides a new breakthrough for the further solution of the integration of two technologies. The development of new manufacturing industry is based on the application of automation technology. The application of the Internet of Things has changed the passive information collection method in traditional automation technology, and has realized the automatic, accurate and timely collection of production parameters in the production process. The traditional industrial production adopts the M2M (Machine to Machine) communication mode to realize the communication between machines, while the Internet of Things realizes the intelligent, interactive and seamless connection between people, machines and systems through the communication mode of ThingstoThings, thus making the connection between enterprises and customers and the market closer, and enterprises can perceive the rapid changes of the market.

For example, in the iron and steel industry, the existence of the Internet of Things enables management and decision makers to grasp the changes in price increases and raw materials in real time, so as to make accurate and reasonable adjustments to production; The management concept based on ERP has changed the management concept, thus improving the management efficiency.

Driven by the development of computer, communication and network technology, the development of industrial communication technology has gone through the stages of analog instrument control system in the 1960s and 1970s, distributed control system (DCS) in the 1980s and 1990s, and field bus control system (FCS) at the end of the 20th century. It is developing towards intelligence and networking.

Formally, the integration of the Internet of Things and factory production equipment can monitor various pollution sources generated in the production process of the factory in real time. When the sensor is applied to equipment and oil and gas pipelines, it can sense the safety status information of workers, equipment and machines, surrounding environment, etc. in dangerous environments. It can also monitor the transportation of dangerous goods and describe the characteristics of each batch of transportation and each batch of materials. In this way, raw materials in each container or bulk cargo can be tracked to provide more security.

In addition to the whole process tracking and monitoring of hazardous chemicals, the factory must be more cautious than before in terms of the demand for water, oil and gas transportation and remote control of equipment during the manufacturing process due to the rising trend of oil and electricity. RFID can be used to track and manage the transmission link between oil and gas resource facilities, improve the safety of oil and gas transportation, and can be used to remotely control the valve switch of oil and gas pipelines, balance the oil and gas flow, thus making the equipment management more intelligent.

The application of the Internet of Things in smart factories has a fairly broad application prospect, with obvious economic and social benefits. The smart factory introduced into the Internet of Things can realize at least the following five functions, namely: electronic work order, transparent production process, controllable production process, accurate capacity statistics, and electronic signage in the workshop. These five functions can not only realize the visualization of manufacturing process information, but also have many effects on production management and decision-making.
