Problems solved by technology

[0002] The alarm system plays a vital role in ensuring the safe production and high-efficiency operation of coal-fired generating units. However, the common problem at present is that there are too many alarm signals, and sometimes hundreds of alarms, causing operators to be unable to deal with these alarms in time, and to ignore the alarm information, or even shut down the alarm system.

Abstract

The invention discloses an alarm optimization method and device based on a single analog quantity and an alarm delayer, wherein the method includes determining the alarm delay parameter n and the alarm threshold xtp as optimization parameters of the alarm system, and setting the false alarm rate and missed alarm rate and the average alarm delay as performance indicators, wherein, n is a positive integer; fixed alarm delay parameter n or alarm threshold xtp, obtain the effective interval of the corresponding alarm threshold xtp or alarm delay parameter n of the above three performance indicators; Calculate the intersection of the effective interval of the alarm threshold xtp or the alarm delay parameter n, if the intersection is empty, then enter the next step; if the intersection is not empty, then get the optimal value of the alarm threshold xtp or the alarm delay parameter n; based on the above three According to the requirements of each performance index, determine the range of the alarm delay parameter n, and then solve the optimal value of the corresponding alarm threshold xtp for each alarm delay parameter within the range of the alarm delay parameter n. The invention improves the performance of the alarm system and the efficiency of alarm processing.

Description

technical field [0001] The invention belongs to the field of signal processing, and in particular relates to an alarm system optimization method and device for a single analog quantity and an alarm delayer. Background technique [0002] The alarm system plays a vital role in ensuring the safe production and high-efficiency operation of coal-fired generating units. However, the common problem at present is that there are too many alarm signals, and sometimes hundreds of The operator cannot deal with these alarms in time, and ignores the alarm information, or even shuts down the alarm system. Because the alarm system is very important to the industry, when the performance of the alarm system cannot meet the requirements, that is, the false alarm rate, false alarm rate and average alarm delay cannot meet the system requirements, it is necessary to redesign the performance parameters of the alarm system. Contents of the invention [0003] In order to solve the above problems,...
