Problems solved by technology

[0004] Regardless of the anti-hazardous core or the anti-hazardous shell, they only isolate key equipment for danger prevention. The actual industrial control system is a complex network, and there is an interdependence between each equipment. The operation of one equipment will inevitably affect other equipment. impact, the hazard prevention for independent equipment often fails to meet the overall hazard prevention requirements

Embodiment Construction

[0023] In order to make the object, technical solution and advantages of the present invention clearer, specific examples are given below to further describe the present invention in detail.

[0024] The single-point state rule divides the entire real number field into seven intervals through the low-risk line, low-critical line, low-warning line, high-warning line, high-critical line, and high-risk line, such as image 3 shown. They are marked 0-6 from left to right, indicating single-point status. The states of all single points in the system are arranged in the order of single point IDs to be single point vectors. Run the single-point rule to get the single-point state vector.

[0025] figure 2 is a bitmap matrix used for user state judgment. In this application example, a 7*n bitmap matrix is ​​used to judge the user status. Among them: 7 represents the seven state quantities after the discretization of the analog quantity, corresponding to {0, 1, 2, 3, 4, 5,...

Abstract

The invention discloses a method for quickly judging an anti-danger state based on a bitmap. In order to improve the efficiency of anti-danger system state judging, a method of bitmap computing is used to avoid the cost of user state rule searching. Through proper initialization, the information of user state rule is converted into a bitmap which is stored in a state bitmap matrix. The design of a bitmap matrix data structure is shown in the abstract drawings. During state judging, the result of state judging can be obtained by taking out the bitmap corresponding to each single point from the state bitmap matrix according to the state vector of the single point and then performing bitwise AND operation. By adopting the method for quickly judging an anti-danger state based on a bitmap disclosed by the invention, the efficiency of state judging can be effectively improved.

Description

technical field [0001] The patent of the invention belongs to computer engineering application software, which is applied to the judgment of the danger prevention state in the industrial control danger prevention safety system. Background technique [0002] With the improvement of information technology and industrial automation, industrial control systems are becoming more and more complex, and errors are becoming more and more difficult to detect and avoid, and often lead to industrial accidents, endangering industrial production, national economic security, and the safety of people's lives and property. Aiming at the security problems existing in the industrial control system, using technologies such as complex network analysis, data forecasting, expert analysis, and self-adaptive upgrading and downgrading, a system including global security, active security, real-time security, autonomous security, and security certification is proposed. The industrial control system cri...
