Product Description

Distributed Control System is abbreviated as DCS, Distributed distributed, so the Chinese meaning of DCS system is "distributed control system" and also called distributed control system. The DCS system is a system to meet the requirements of large-scale industrial production and increasingly complex process control. From the perspective of integrated automation, process control and process monitoring are integrated together, combined with 4C technology, computer (Computer), communication (Communication), display (CRT) ) And Control, a new type of control system developed. The design concept of the DCS system is: decentralized control, centralized management, hierarchical management, flexible configuration and convenient configuration. Features of the DCS system: Reliability The design of the DCS system basically adopts a redundant design. The meaning of redundancy is to design the important equipment of the system, CPU and various modules in the form of one-use and one-backup. When a certain CPU Or when the module fails, the standby equipment will work immediately, or you can choose to work at the same time, so as to reduce the system breakdown caused by the failure of key equipment. The open system adopts an open platform, systematization, modularization, and standardization. Each interconnected computer system can realize centralized interconnection and mutual access through communication methods such as Ethernet. When there is a need to increase or decrease the system, it can directly control the modules of the system. Increases and decreases are more convenient for system design and maintenance. The modular DCS system has developed to the present, and it is more inclined to modular design. All core equipment has become modular design, such as CPU, power supply, I/O module, communication module, AI/AO module, these devices, All are designed as independent modules. Assembling a cabinet, you only need to install the base of the module and install the corresponding module on the base to realize the hardware installation. Each module integrates its own CPU, with processing functions, the processing speed is faster, and at the same time, the modules do not interfere with each other. If a problem occurs in a module, it will not affect other modules, and it supports hot swapping.
