Embodiment Construction

[0031] In order to make the purpose, content and advantages of the present invention clearer, the specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0032] This embodiment proposes an industrial control system design method. The technical solution is to divide the industrial control system into three parts: the production process control layer, the signal acquisition and transmission layer, and the data information reading layer for design, and each layer implements different responsibilities. . The specific technical solution of the present invention is: (1) The production process control layer is responsible for the near-end and remote control of industrial production, and uploads information such as copying and shunting sensor signals, CPU control instructions, etc. to the upper network space; (2) the signal The acquisition and transmission layer is responsible f...

Abstract

The invention relates to an industrial control system, which belongs to the field of industrial control. In order to overcome the problem that the existing network protection technology is difficult to meet the requirements of industrial control for simplicity, low cost, and easy operation of the system, and the designed industrial control system should have a good network security protection function, a layered design is adopted. method, the industrial control system design product production process control, information collection and transmission, and data information reading are three layers, and the analog and digital signals in the production process of the product are introduced into the shunt, and the production process control and data of the product are controlled by the photoelectric coupling isolator. The information is isolated from the external link process. The layered design method adopted by the present invention and the introduced shunt and photoelectric coupling isolator can effectively ensure the real-time performance of information transmission, and at the same time, can isolate the penetration attack of the external network on the control process of the product production process, so it can greatly improve Security protection for modern industrial control systems.

Description

technical field [0001] The invention belongs to the field of industrial control, and in particular relates to an industrial control system. Background technique [0002] With the deep integration of industrialization and informatization, security issues of industrial control systems are constantly emerging, and the number of security incidents in the field of industrial control has remained high, involving industries such as transportation, energy, and public utilities. Industrial control system security risks will bring about the loss of physical assets such as equipment and products, and pose a serious threat to the industrial foundation and economic lifeline. Once the industrial control system is breached, it will directly affect the product production control process in the real physical world, and extremely serious accidents will easily occur. [0003] At present, the infiltration attack on the industrial control system has changed to start from the infiltration of the...
