System principle and design analysis of industry 4

Introduction: to achieve industrial 4 is likely to take 10 years or even 20 years, but has affected the system design of every hue. The connectivity of the factory floor will drive the continuous improvement of the software and algorithms, greatly improving the productivity and forecasting ability.
OFweek industrial network: in the automation industry, everyone heard a buzz word: industry 4. The concept of the industry indicates that the high level of integration, automation and flexibility of the future plant, the plant will be fast and efficient delivery, to meet market demand.
Obviously, the fourth manufacturing and process automation revolution will occur in the backbone of the system interconnection: sensors, actuators, control systems, etc. all through the internet protocol to connect to different types of network. Once all machine / sensor data is located in the cloud, it is able to perform a profound analysis of the meaning of production optimization, fault prediction, develop maintenance plans, automatic replenishment of inventory, and even customized end product indicators to meet the dynamic changes in the market.
We believe that the current fourth industrial revolution is taking place, and that the connectivity of the factory floor will drive the continuous improvement of the software and algorithms, greatly improving the productivity and forecasting ability. This is indeed impressive, practical. However, we must solve many system design problems before the infrastructure and the real outbreak of the revolution. This paper focuses on some of the key system design challenges.
System level design considerations for industry 4
The realization of industrial 4 is likely to require 10 years or 20 years, but has been affecting all kinds of system design. The automated process shown in Figure 4 shows that when we move towards industry three, we must implement the 1 key design.
Figure 1 Industrial 4 is driving the three aspects of the basic industrial system requirements: distributed computing and control, pervasive sensing, authentication and security systems.
Distributed computing and control - a key trend in the beginning is the localization of the calculation and control system. In order to improve the flexibility of the complex assembly line, reduce the control delay and alleviate the pressure of the main PLC. In the next generation, it will become more and more popular. The size of PLC will continue to shrink, and the number of processed I/O channels is increasing, including analog and digital. PLC will have to support a variety of different I/O protocols, including new protocols, such as IO-Link standards.
Ubiquitous sensor - how to deal with each sensor? The basic premise of industry 4 is to share manufacturing data, but this means that we must first collect the growing volume of data. Mass data come from the explosive growth of the number of sensor systems, including factory and process equipment, and throughout the remote operation. Even if the process parameter does not affect the users current control algorithm, it is necessary to collect the data for future use. It can be expected that the fast and explosive innovation of the cloud operating algorithm may eventually "create a new" process parameters to predict the important system failure mechanism. In the industrial field, a word that describes the rapid growth of the sensing scheme is called "universal" ".
