Industrial Automation Control System Solution
With the rapid development of Industry 4.0 and intelligent manufacturing, industrial automation control systems are playing an increasingly important role in the production process. Ring network transmission technology, as an important communication method in the field of industrial automation, has the characteristics of high reliability and fast response, and has therefore been widely used in industrial automation control systems. This article will introduce an industrial automation control system scheme based on switches forming a ring network transmission to improve production efficiency, reduce energy consumption, and ensure system stability. The following is a specific plan
Scheme description:
System Overview
The equipment of each production line is controlled by a main PLC, and each main PLC needs to communicate with other main PLCs and data servers through optical fibers to complete
the automation operation of the entire production line. During the construction and operation of the production line, there may be limited space, vibration, electromagnetic interference,
and other impacts. In such an environment, it is important to ensure accurate data exchange between the front-end and back-end. So the communication products that need to be
installed on the production line have good anti vibration and impact effects, good anti electromagnetic interference capabilities, and are small in size and easy to install.
Project networking
The access layer adopts gigabit ring network industrial grade Ethernet switches, and establishes regional gigabit ring network redundancy on a production workshop basis. The workshop
ring network is connected to the central aggregation core switch based on the characteristics and specific needs of the carried business. The second layer ring network of the access
layer adopts our company's own fast self-healing protocol SC Ring, with a network self-healing time of less than 15ms, ensuring uninterrupted switching of the network.
The aggregation core layer adopts gigabit/ten thousand optical devices. Design a reasonable network capacity and select appropriate equipment based on the actual size of business
data traffic. Security management: Logically close all unused network ports of the access switch.
Advantage analysis
High reliability: Ring network transmission technology can ensure network connectivity, avoid system paralysis caused by a node or link failure, and improve system reliability.
Fast response: Ring network transmission technology can quickly respond to changes in the network, ensuring the real-time and accuracy of control instructions. Core switches
and access switches should have high-speed data transmission capabilities to achieve rapid response.
Ease of Management: Core switches and access switches should have simple and easy-to-use management functions for administrators to configure and manage. At the same
time, the network management system should also have a user-friendly interface and powerful management functions to improve management efficiency.
Low energy consumption: Terminal devices should have low-power design to reduce the energy consumption of the entire control system. At the same time, core switches and access switches should also have energy-saving designs to further reduce energy consumption.
