Embodiment Construction

[0042] The preferred embodiments will be described in detail below in conjunction with the accompanying drawings. It should be emphasized that the following description is only exemplary and not intended to limit the scope of the invention and its application.

[0043] One purpose of the present invention is to add data filtering on the basis of automatic alarm suppression, and at the same time, adopt process historical data optimization design for alarm processing parameters, thereby overcoming the lack of operator information if a certain alarm is automatically suppressed for a long time . When determining the alarm processing parameters, the optimal design of process history data is adopted to ensure the practicability and accuracy of the method.

[0044] The steps of the present invention are:

[0045] Step 1: Use the historical data of the variable process to optimize the design of the variable alarm processing parameters, and store the obtained optimized filter window,...

Abstract

The invention discloses a repeated alarm processing method based on data filtering, and belongs to the technical field of alarm management. The method comprises the following steps of: optimally designing variable alarm processing parameters by virtue of variable historical process data, and storing the obtained optimal alarm processing parameters in an alarm parameter database; acquiring real-time process data from a real-time database or a distributed control system (DCS); then obtaining window filtering parameters from the alarm parameter database, and filtering the real-time process data;and finally carrying out repeated alarm judgment on the filtered real-time process data, automatically inhibiting the repeated alarm if the repeated alarm is judged, and otherwise displaying alarm information. The repeated alarm processing method has the beneficial effects that the noise effect in the real-time process data is eliminated, the quantity of occurrence of repeated alarms is reduced and the purpose of alarm management in the process industry is achieved.

Description

technical field [0001] The invention belongs to the technical field of alarm management, in particular to a method for processing repeated alarms based on data filtering. Background technique [0002] Alarm systems play an important role in the process industry. When an alarm is activated, the operator should find out the cause of the alarm and take corrective action to eliminate the abnormality and return the device to normal state. With the emergence of DCS (Distributed Control System), the alarm setting becomes easier, which makes the number of alarms in the alarm system increase sharply. Due to the lack of effective management of the alarm system, it is easy to generate a flood of alarms under abnormal working conditions, which has a negative effect on the operator's correct handling of device abnormalities. Flooding of alarms to operators from a poor alarm system is often one of the leading causes of accidents. Historically, major accidents such as the explosion at T...
