DCS development trend, what is DCS

Are you talking about distribution control?

Summary. DCS, distributed control system is a new generation of instrument control system based on microprocessor, which adopts the design principles of decentralized control function, centralized display operation, autonomy and comprehensive coordination. Distributed control system is referred to as DCS, which can also be literally translated as "distributed control system" or "distributed computer control system".

DCS, distributed control system is a new generation of instrument control system based on microprocessor, which adopts the design principles of decentralized control function, centralized display operation, autonomy and comprehensive coordination. Distributed control system is referred to as DCS, which can also be literally translated as "distributed control system" or "distributed computer control system".

It adopts the basic design idea of decentralized control, centralized operation and management, and adopts a multi-level hierarchical, cooperative and autonomous structural form. Its main feature is its centralized management and decentralized control. DCS has been widely used in various industries such as electric power, metallurgy, and petrochemical.

Qinghai Qianyi Warehousing Insurance Company is a dry piece.

The Company's business scope: General items: general cargo warehousing services (excluding hazardous chemicals and other items subject to license approval); Chain management services; technical services, technology development, technical consultation, technology exchange, technology transfer, technology promotion; storage of refined oil products (excluding hazardous chemicals); information consulting services (excluding licensed information consulting services); **Brokerage; Domestic****; Leasing of non-residential real estate (except for projects subject to approval in accordance with the law, independently carry out business activities with a business license in accordance with the law).

Pros: Anything can be achieved in a large control room in a factory, you don't need this, so what do you use?

Cons: Expensive wow! There are many configurations of hardware and software, and there are many things to learn.

A hierarchical and progressive structure is usually adopted, and each level is composed of a number of subsystems, each of which achieves a number of specific finite goals, forming a pyramid structure. Its main feature is its centralized management and decentralized control.

DCS, the so-called distributed control system, or in some sources as a distributed system, is relative to centralized.

DCS is a distributed control system.

To put it simply, it is distributed control management, and the early instrument control system is also in use now.

DCS is the English abbreviation of distributed control system, which is also called distributed control system in the domestic automatic control industry. That is, the so-called distributed control system, or in some data called distributed system, is a new type of computer control system relative to the centralized control system, which is developed and evolved on the basis of the centralized control system. It is a multi-level computer system composed of process control level and process monitoring level with communication network as the link, integrating computer, communication, display and control and other 4C technologies, and its basic idea is decentralized control, centralized operation, hierarchical management, flexible configuration and convenient configuration.

Personal understanding: DCS is just a concept, and it is relatively simple to apply it in practice, which is to realize the process of automatic or remote manual control of the equipment on the site through computer hardware and software.

DCS refers to a complete set of digital equipment that uses a mouse to control the rotation and stop of electrical, instrumental, and mechanical equipment. See the encyclopedia for details.

The landlord reads the encyclopedia himself, I don't want to say it.

The following views are purely personal opinions: If there is any inappropriate wording, netizens should not attack!

Up to now, there have been a lot of DCS manufacturers in China, both large and small, but I personally think that it is better to be in Hangzhou and Lysys, Zhejiang University Central Control, and Zhejiang VIA! It is regarded as the three most powerful and prestigious in China.

Hollysys diversified development, performance is mainly concentrated in the power industry and the northern region, DCS is just a division of Hollysys.

Zhejiang University Central Control, whose performance is mainly in the south, has done well, but I heard that it may follow the old path of Shanghai Xinhua - to be sold. Finally disappear.

Zhejiang VIA, I heard that it only does DCS, and does not do anything else, the company is very professional and has good performance. It's just that the company doesn't grow so fast.

Zhejiang University has too little performance. It was acquired by Chint and became Chint Zhongzi, which basically existed in name only.

Shanghai Xinhua was acquired by GE, and there was basically no one left, and a company suddenly became a department.

There are also some other companies in Guodian, which are not on the list, basically they are small companies that have just been established for 1-2 years, not to mention the performance.

As for foreign DCS, there are many brands, and the quality is not bad, but it is too high, if the domestic general project, it would be good to use the domestic one, there is no need to spend so much silver, after all, the domestic DCS after almost 20 years of use, technology and quality are worthy of everyone's trust. Support domestic products!

The information on the first floor is outdated.

The current situation that I have been exposed to and understood is:

There are many DCS brands in China, but they all have their own strong professional range.

There are several famous brands, Zhejiang Central Control (the original Zhejiang University Central Control), now the development is very good, the new ECS700 system can be said to have made great progress, mainly for the chemical field, and will expand to the direction of power in the future.

Hollysys: The profession is concentrated in the power industry, the performance of power is good, and the stability and reliability of the system have gradually caught up with foreign countries. However, it is not as fast as Zhejiang Central Control.

Shanghai Xinhua: After being acquired by GE, some of the technical staff have now started to develop the DCS system again, and are now working hard to develop the DCS system.

Zhejiang VIA: In the past few years, DCS manufacturers have been very well-known, known for their stable and reliable quality, but in recent years, there seems to be no new products launched, and the pace of development has gradually lagged behind.

The FB-300MCS launched by Zhejiang VIA in 07 is used in our resin project: the quality is stable and good, and there have been basically no problems in 08. Support domestic products, but a little advice for VIA is:

In addition to DCS, we should also develop other control systems or instruments to diversify our development, after all, the market competition is very fierce. Isn't the diversification of Hollysys and Zhejiang University Central Control developing very well? Peers can learn from it!

Zhejiang Central Control, and Lexis.

These two should be doing better in China at present, with different industry priorities and their own strengths.

As far as engineering services are concerned, Zhejiang Central Control Service is relatively good with Lishi.

Distributed control.

to the system. DCS is the English abbreviation of distributed control system, which is also known as ZHI distributed control system in the domestic automatic control DU industry.

It is a new type of computer control system relative to the centralized control system, which is evolved on the basis of the centralized control system.

The backbone of DCS—the system network, which is the foundation and core of DCS. Because the network plays a decisive role in the real-time, reliability and scalability of the entire DCS system.

PLC: Programmable Logic Controller is an electronic system designed for digital operations in industrial environments. It uses a programmable memory to store instructions for performing operations such as logic operations, sequence control, timing, counting, and arithmetic operations, and controls various types of mechanical equipment or production processes through digital or analog inputs and outputs.

DCS is the abbreviation of distributed control system, which is generally called distributed control system in China. It is a multi-level computer system composed of process control level and process monitoring level with communication network as the link.

Features: high reliability, openness, easy maintenance, coordination, complete control functions.

DCS is the English abbreviation of distributed control system, which is also known as the distributed control system in the domestic automatic control industry. Capacity is a new type of computer control system relative to the centralized control system, which is developed and evolved on the basis of the centralized control system.

PLC: PLC (Programmable Logic Controller) is a device used to replace sequential relay circuits used for motor control. The PLC controls the closure and opening of its output points by checking the status of the input.

The user enters a program (usually via software) and the PLC gives the corresponding result. The figure below shows a typical PLC system, which consists of a power module, a CPU, and a signal module.

DCS also has another meaning, distributed cache du

Distributed Cache Service in English.

Keyuan NT6000 decentralized control copy system is based on more than ten years of technology accumulation.

"Easy to use outside, strong in the core; Unlimited speed and control; Digital interconnection, information presentation" brand appeal embodies Keyuan's understanding of the essence of DCS products and unremitting pursuit, more reliable, easier to use, more advanced, strict and progressive requirements will achieve ambitious leading products.

DCS is the English abbreviation of Distributed Control System (BAI).

dudistributed control system), in the domestic automatic control industry again.

Zhi calls it a decentralized control system. It is a new type of computer control system relative to the centralized control system, which is developed and evolved on the basis of the centralized control system.

It is used in industrial control and is widely used in petrochemical, chemical, electric power and other industries. In short, through the operation of the computer in the control room, the control of field equipment and materials is realized. The reason why it is called a discrete control system is because its principle is "centralized control, disperse risk".

The knowledge to be used, including the knowledge of control principles, automatic detection technology, instrumentation, electrical, etc.; In terms of software, each company is different, but it is basically based on the Windows platform and database technology.
