Embodiment Construction

[0033] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0034] Such as figure 1 As shown, a nuclear power plant digital alarm classification partition method, the method specifically includes the following steps:

[0035] Step 1, classify and partition the alarm trigger signals of the nuclear power plant;

[0036] Step 1.1, carry out hierarchical processing to the alarm trigger signal of the nuclear power plant;

[0037] Divide the collected and obtained alarm trigger signals into three levels, among which, the first level is the alarm trigger signals of nuclear island (NI) and conventional island (CI), and carry out color, display shape, font and action behavior on the first level alarm interface The second level is the combined alarm trigger signal, which is displayed through the combined alarm interface; the third level is a specific trigger signal in the combined alarm trigger signal...

Abstract

The invention relates to the technical field of nuclear power plant digital alarm design, and specifically discloses a nuclear power plant digital alarm grading and partitioning method. The method includes: 1. Carrying out classification and division of the alarm trigger signal of the nuclear power plant; 2. Obtaining the alarm trigger signal; 3. Using the alarm trigger signal to trigger the third-level alarm interface; 4. Using the third-level alarm signal to The second-level alarm interface is triggered; 5. Use the second-level alarm signal to trigger the first-level alarm interface; during normal operation, the operator can view the latest alarm through the latest alarm area and take corresponding actions. Corrective measures; when a large number of alarms occur under transient conditions, the operator can quickly locate and give priority to important key alarms through key function partitions or system partitions, so as to make accurate judgments and avoid unit state deterioration; at the same time, the alarm Displayed on the big screen in the main control room, it is intuitive and eye-catching.

Description

technical field [0001] The invention belongs to the technical field of nuclear power plant digital alarm design, and in particular relates to a nuclear power plant digital alarm grading and partitioning method. Background technique [0002] The alarm system is the main component of the main control room of the nuclear power plant. Its function is to promptly remind the operation in a special way (color change, sound and light alarm) when the process system of the nuclear power plant or the instrument and control system is abnormal. Operators, so that operators can take effective actions and corrective measures to avoid deterioration of equipment status, and even threaten the safety of the power plant. [0003] With the development of digital technology, the traditional analog alarm system is gradually replaced by digital alarm system. Digital technology is beneficial to enhance the function of the alarm system, but if the man-machine interface is not designed properly, it wi...
