The new generation of advanced intelligent sensors will become the heart of industrial automation. "Intelligent factory" refers to the use of Internet of Things technology and equipment monitoring technology to strengthen information management and services on the basis of digital factory, clearly grasp the production and marketing process, improve the controllability of production process, reduce manual intervention on production line, timely and correct collection of production line data, and reasonable production planning and production progress. The realizable technologies of intelligent factory include wireless sensor, networked control system and wireless industrial communication. Some product quality indicators (such as viscosity, hardness, surface finish, composition, color and taste, etc.) are quickly and directly measured and controlled online. Sensors fused with intelligent technology can solve the above problems very well.
Sensors are widely used. All components of industrial production need to be monitored by sensors, and the data are fed back to the control center in order to intervene in time for abnormal nodes and ensure the normal operation of industrial production.
It is generally believed that the heart of industrial automation is a new generation of advanced intelligent sensors. It enables the product line to run continuously and connect to high-performance programmable logic controller (PLC) and human-machine interface (HMI) systems through low latency and real-time network. Of course, for manufacturers, time is money. As long as the manufactured products can reach the required quality level, the production line will continue to run as fast as possible, and the importance of smart sensors is highlighted.
At present, as the most influential and promising high-tech in the 21st century, smart sensors are attracting great attention from the electronic information industry at home and abroad. The Optoelectronic Industry Development Association (OIDA) predicts that the international market sales of smart sensors will grow at a high rate of 20% per year, and smart sensors will play a more important role in the era of industrial automation.
Internet of Things (IOT) technology has brought changes to industrial automation. At present, industrial production is indeed changing to automation on a large scale. However, with the continuous commercialization of Internet of Things and cloud platform applications, the development of automation in industrial field tends to upgrade to a higher level, that is, intelligent production.
