Embodiment Construction

[0020] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0021] The present invention designs a safe industrial control system based on a safe intelligent controller. The specific method is to embed the safety protection function from each unit of the system to realize the automatic control of the local industry and the data communication with the upper computer; Such as figure 1 As shown, it includes the PLC controller and the input and output modules. The input and output terminals of the PLC controller are connected to the designated equipment in the local industry through the input and output module. The control logic performs logical processing on the collected signals, obtains control signals, and feeds back the control signals to each designated device for automatic control.

[0022] In practical applications, the input and output modules support discrete and analog in...

Abstract

The invention relates to a safe industrial control system based on a safe intelligent controller, which is composed of a PLC controller, an input and output module and a host computer. The encryption system realizes security protection from the main body of the infection, and cooperates with the input and output modules and the host computer to form a set of industrial control system with pure security protection. This industrial control system is in each link of the host computer, PLC controller and input and output modules All have a security protection system to achieve multiple protections. Even if one link is attacked, there will be no major accidents such as misoperation. The other two links will comprehensively check and judge, make fault handling, and immediately take safety measures to prevent accidents from expanding.

Description

technical field [0001] The invention relates to a safe industrial control system based on a safe intelligent controller, belonging to the technical field of intelligent controllers. Background technique [0002] Industrial control systems are widely used in various industries. From a broad perspective, any occasion where industrial control equipment can be applied can be called an industrial control system. Whether it is manufacturing or processing production, it is inseparable from the industrial control system. Especially in critical infrastructure, such as chemical industry, water conservancy facilities, financial services, commercial facilities, defense industry, food industry, communications, emergency response, government facilities, key manufacturing, energy, public health, water treatment , information technology, nuclear reaction facilities, transportation systems and other important sectors that support modern society. It is precisely because of the importance of...
