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, ignoring the alarm information, or even shutting down the alarm system.
In order to judge whether the performance of the alarm system meets the requirements, it is necessary to correctly evaluate the performance of the existing alarm system, but currently there is a lack of accurate definitions and calculation methods for the evaluation indicators of alarm performance.

Abstract

The invention discloses an alarm system evaluation device based on a single analog quantity and an alarm delayer, wherein the method includes: using a Markov chain to describe the delay alarm mechanism of an alarm system with preset alarm delay parameters; In the alarm mechanism, the alarm state corresponding to the alarm signal sampling time is determined according to the comparison between the single alarm signal sampling value and the alarm threshold; according to the alarm state and its occurrence probability described by the Markov chain, the performance index value of the alarm system is obtained; Comparing the obtained performance index values ​​of the alarm system with the corresponding preset performance index standard value ranges, so as to judge whether the performance of the alarm system meets the requirements. The invention can quantitatively evaluate the performance of the alarm system, judge whether the performance meets the requirements, and provide a reliable basis for optimizing the performance of the alarm system, thereby reducing interference alarms, improving the efficiency of on-site operators in handling alarms, and ensuring production safety.

Description

technical field [0001] The invention belongs to the field of signal processing, in particular to an alarm system evaluation method and device based on 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, ignores the alarm information, or even shuts down the alarm system. In order to judge whether the performance of the alarm system meets the requirements, it is necessary to correctly evaluate the performance of the existing alarm system, but at present, there is a lack of accurate definition and calculation methods for the evaluation indicators of alarm performance. Contents of the invention [0003] In order to solve the above problems, the first object of the pre...
