The Development History of DCS
After the 1960s, with the large-scale and complex production engineering, a centralized control system with centralized computer monitoring and control was born. Centralized control facilitates monitoring, operation, and management, as well as highly concentrated hazards. Once the system malfunctions, the impact and danger to the device are significant. With the birth of microprocessors, unparalleled conditions have been created for the opening of new control systems. In 1975, with the continuous development and improvement of computer, communication, control, and CRT 4C technology, Honeywell in the United States launched the distributed control system tdc-2000 to the world. Since the birth of DCS, the DCS system has gone through three stages of development.
The period from 1975 to 1980 was the initial stage. Due to limitations in software and hardware technology, the performance of the dcs system at this time is not yet very complete, and the hardware structure is not yet very mature.
The second stage was from 1981 to 1987. During this period, fault-tolerant and redundant technologies have become mature and widely used, with high system reliability and superior performance, and a variety of control functions. At this stage, dcs developed from simple industrial process automation control to production management automation. This generation of dcs mainly introduces lan (local area network) technology, greatly enhancing the network functionality of dcs.
1987 has been the third stage of development. Manufacturers adopt the Open Systems Interconnection (OSI) architecture of the International Organization for Standardization (ISO) to generate Manufacturing Automation Protocol (Map) standards to address the interconnection issues of different models. The DCS system uses more advanced CPU and redundancy technology in hardware, greatly improving storage capacity and communication speed, and using a universal operating system in software. At this stage, DCS organically combines control, supervision, and management scheduling to achieve automated management of various production and operation information.
3.3 Characteristics and Functions of DCS
(1) The main characteristics of dcs. DCS has the following main characteristics: separation of control and display; Adopting network communication technology; A complete open system; High reliability; Having comprehensiveness and professionalism; Implemented human-machine dialogue technology; Flexible system expansion; Strong management skills.
(2) The main functions of dcs. The dcs system can effectively complete industrial continuous control, loop instrument control, etc. Its years of practice have shown that it has become a mature technology and a complete control system in the field of continuous control. At the same time, its friendly human-machine interface, reliability based on redundant technology, powerful network functions, single database, flexible configuration, and other characteristics have been praised by a large number of users.
3.4 Development Trends of DCS
Dcs holds an extremely important position in the field of continuous control. So far, there have been many controversies about the future development of dcs, but the following issues are the ones that most people believe are urgently needed to solve in dcs;主营产品，优势供应，足够库存：

 The video image sensor collects video image information under the control of FPGA. After receiving the acquisition command from the PC, the MB86S02 starts to collect video signals. FPGA, as the core control unit of the system, is not only responsible for the collection of video images, but also for the preprocessing of video image information and data interaction between various unit modules of the system. In response to the large amount of video image data, in order to ensure the real-time requirements of the system, the system uses a large capacity off chip SDRAMR to cache the collected video image information. The SDRAM controller is implemented by FPGA, and after the video image information is cached by SDRAM, it first needs to be filtered and processed by FPGA to eliminate noise interference in the image information. In this system, median filtering is used to process the collected video information, The filtered data enters the DSP through the internal FIFO of FPGA for the next step of compression processing. After the DSP is powered on, it first performs self loading of the boot program and waits for the FPGA to send a request. After receiving the request from the FPGA, the DSP establishes an EDMA channel to obtain video data from the FPGA. After storing a full frame, it starts JPEG compression processing of the video image. After the compressed video image information is cached in FIFO, it is written into the data cache area of the USB interface controller under the control of the FPGA and waits for the reading request from the PC, After receiving a reading request from the PC, the USB interface controller writes the data to port 1 of PDIUSBD12 for the PC to read the data in the next step.
Dcs holds an extremely important position in the field of continuous control. So far, there have been many controversies about the future development of dcs, but the following issues are the ones that most people believe are urgently needed to solve in dcs;
(1) Openness. Regarding openness, this issue is a significant constraint on the development of DCS. Due to the strict confidentiality measures taken by DCS manufacturers for their network protocols and system software, it is impossible for PLCs or other control devices from other manufacturers to seamlessly connect to the DCS control system, often requiring complex protocol conversion, resulting in unsatisfactory communication rates and capabilities, For example, communication between Honeywell's TPS system and AB's PLC5 series PLC requires the use of serial ports and auxiliary equipment developed by both parties for communication. However, when the communication volume is large, the timeliness is greatly reduced, which hinders the application field and competitiveness of DCS. At present, some DCS manufacturers have realized the seriousness of this problem. In addition to communication issues, there are also open issues in operating systems, databases, human-machine interfaces, control strategy configurations, and other aspects. Therefore, with technological progress, the openness of DCS needs to be gradually strengthened, and its characteristics should also be utilized to liberate decentralized computer control systems from traditional DCS and enable the scheduling and management layers of DCS and CIPS systems The decision-making layer (auxiliary decision-making layer) seamlessly connects and uploads relevant information of DCS, enabling real-time database
