I would like to share with you the main performance of the application of computers in realizing industrial automation. I believe that most people do not know much about it, so share this article for your reference. I hope you will gain a lot after reading this article. Let's learn about it!

The application of computer in realizing industrial automation is mainly manifested in real-time control; real-time system can be divided into real-time control system and real-time information system, the main difference between them is the service object and the requirement of response time; real-time control system is usually a computer-centered process control system, also known as computer control system.

The application of computer in realizing industrial automation is mainly manifested in real-time control.

Process control of modern industrial production. A real-time system is a computer system that can perform calculations or process transactions and respond to external events within a certain period of time.

Real-time system can be divided into real-time control system and real-time information system. The main difference between them is the service object and the requirement of response time. Real-time control system is usually a computer-centered process control system, also known as computer control system.

(Concurrent Control) in the form of direct supervision, control is carried out while the work is in progress, while correcting actions and correcting problem deviations, such as aircraft positioning systems. With the development of industrial modernization, the production scale continues to expand and the production process is becoming more and more complex, which requires not only superior control performance, good performance / price ratio, but also high reliability, flexible composition and simple operation methods. So find a more effective control system.

The most important feature of the basic controller is its real-time performance. The so-called "real-time" means that the microcomputer processes the input information at a fast enough speed and reacts or controls within a certain period of time. Beyond this time, the timing control loses its meaning.

Real-time performance

The real-time performance of the computer control system refers to the characteristics that the computer system should have in industrial control, which can respond to external events in a limited time.

In the computer control system, the way in which the production process is directly connected to the computer and controlled by the computer is called online mode or online mode. In the production process is not connected to the computer, and is not controlled by the computer, but rely on people to contact and do the corresponding operation of the way called offline mode or offline mode. According to the working principle of the computer control system, the computer control system should carry out real-time data acquisition, real-time control decision-making and real-time control output. In the production process, the system should track and make CPU/MEM man-machine interface system support board analog output (AO) channel analog input (AI) channel digital input (DI) channel digital output (DO) channel actuator disk adapter controlled object electrical switch internal bus measurement to industrial control computer PIO equipment production process real-time response Therefore, the computer control system should consider real-time.

Real-time system

Real-time system (Real Time System) is another kind of special multiprogramming system, which is mainly used in fields that need to respond and deal with external events in time.

Real-time system can be divided into real-time control system and real-time information system. The main difference between them is the service object and the requirement of response time. Real-time control system is usually a computer-centered process control system, also known as computer control system. It is not only used for automatic control in the production process, including automatic data acquisition, production process monitoring, automatic control of actuators and so on. It can also be used to monitor guidance control, such as guidance of weapons and equipment, traffic control, autopilot and tracking, launch of missiles, rockets and aerospace vehicles, etc. According to the different control objects, such control system can also be divided into open-loop control and closed-loop control. The real-time information system usually refers to the real-time information processing system, which can be a host-type multi-terminal online system, a remote online (Online) information service system, or a network interconnected information system.

As the information processing computer receives the service request from the end user or the remote end user, the system retrieves, searches and processes the data and information by category, and feedback it to the user in time. The development of real-time information system is inseparable from the specific application fields, such as air ticket booking system, information retrieval system, information query system and so on.

The above is all the contents of the article "where is the application of computers in realizing industrial automation?" Thank you for reading!
