What is the difference between an integrated automation control system for industrial production pro

The automated manufacturing system includes rigid manufacturing and flexible manufacturing, and the meaning of "rigid" means that the production line can only produce a certain type of product or a certain type of product with a similar production process, which is manifested as the singleness of the production product. Rigid manufacturing includes combined machine tools, special machine tools, rigid automatic production lines, etc.

"Flexibility" refers to the diversity and variability of production organization forms and production products and processes, which can be specifically manifested as the flexibility of machine tools, the flexibility of products, the flexibility of processing, and the flexibility of batches. Flexible manufacturing includes flexible manufacturing unit (FMC), flexible manufacturing system (FMS), flexible manufacturing line (FML), flexible assembly line (FAL), computer integrated manufacturing system (CIMS), etc. The following is classified according to the production capacity and intelligence of the automated manufacturing system.

If it is divided into two parts, it can be divided into two parts: mechanical equipment and control system;

If the automation system itself is divided, it can be divided into drive system (i.e., motor, hydraulic pump and other equipment), power cabinet (used to control power output, generally including frequency converter, 380V output circuit, etc.) and control cabinet (used for system control, including PLC, various relays, etc.);

If it is divided according to the voltage level, it can be divided into low-voltage electrical part (380V and below) and high-voltage electrical part.

With the continuous development of science and technology, automatic control theory and computer network technology have also developed rapidly. In the process of automobile manufacturing, the control of a single motor can no longer meet the process requirements in the actual production process, and more and more processes require multiple motors to be controlled at the same time, especially in large coating lines. The synchronous control of multiple motors has become an important topic in the development of the industry.

Among the commonly used AC speed regulation methods, frequency conversion speed regulation has good characteristics. It is widely used and is also the most researched AC speed control technology. The control principle and application of automatic production line are briefly introduced, and the speed synchronization method and actual speed synchronization adjustment of the production line are classified.

The basic design ideas and theories of single-chain multi-machine synchronization and multi-simple collapse chain synchronization technology are introduced in detail.

A complete set of industrial automation control system consists of five parts:

Mechanical body. Control section.

Dynamical system. Sensor actuators.

PLC DCS, (control system) measuring elements (e.g., flow meters, thermometers, pressure sensors), control elements (various regulating instruments), and actuators (e.g., control valves, actuators) are mainly composed of these.

Machinery manufacturing and automation is a large discipline or refers to the characteristics or conditions of the entire industrial industry, including many theoretical studies and technical routes. Biased to the "macro". It is not limited to the manufacture of a specific product or commodity.

The automation of the production process generally refers to the level of automation in the production and manufacturing process of specific products or commodities in a specific enterprise, which is "micro".

That's the main difference. Of course, there are some similarities between the two on the surface, such as the advanced level of equipment, equipment, automatic control systems, etc., but one is a macro object, and the other is to solve micro problems.

Machinery manufacturing and its automation are mainly biased towards mechanical design and mechanical application, and those who understand and contact some automation processes, applications and technologies are mainly at the technical level.

The automation of the production process is mainly biased towards the production automation scheme, and the production process management is mainly biased towards the paperwork and management.

Machinery manufacturing and its automation refers to the automatic nature of the machinery itself, while process automation refers to the automatic control and monitoring of the production process in reproduction.

The automation of the production process refers to the direction of instrumentation.

Machinery manufacturing and its automation refer to the direction of production of CNC machine tools.

I don't know about the large range of industry, but I understand the integration of DCS automation control system in sugar mills.

Generally, it is composed of a controller, an actuator, a control object, a detection and transmission part and a comparison part. These are the building blocks.

The control quantity signal, the dust output signal, the measurement signal and the given value of the letter brother filial piety flow between the parts. All of this is combined into a conventional closed-loop control system.

Of course, the actual system must not be able to produce a power supply and other devices.

The general composition is: setpoint - control algorithm - actuator - control object - measurement transmitter - setpoint, cycle repeatedly.
