Embodiment Construction

[0055] Provide the concrete implementation method of the present invention below. The input data for alarm limit calculation generally comes from real-time data on the industrial site, data once every 5 seconds or once every 10 seconds is enough, and data with too high frequency is not required. Under normal circumstances, the calculation of the small period is performed once an hour, and the calculation of the large period is performed once a month.

[0056] In the initialization phase, the values ​​of the following calculation parameters need to be initialized:

[0057] Data sampling frequency: default 5-10 seconds

[0058] Number of data partitions: 20 by default

[0059] Number of extended partitions: default 3 (extend three intervals at the top and bottom)

[0060] Upper and lower overrun alarm interval data threshold: default 0.25%

[0061] Upper and lower limit alarm interval data threshold: default 5%

[0062] Normal data interval (from low limit to high limit) da...

Abstract

The invention discloses an industrial process data-based method of an alarm limit self-learning system, belonging to the technical field of automatism of industrial manufacturing. The industrial process data-based method comprises the following steps of: firstly, dividing date into different intervals according to different algorithmic rules; secondly, computing a data accumulating amount according to a certain cycle and a frequency value for the data in each interval; thirdly, continuously processing according to the cycle till the end of a major cycle, and computing to obtain an accumulating value of the whole major cycle and the data distribution condition of each interval; and fourthly, computing alarm limit information by using an algorithm according to the accumulating data and the frequency data. The industrial process data-based method of the alarm limit self-learning system has the advantage that the limitation that the alarm limit is set manually is overcome and a method for computing the alarm limit on line can be realized.

Description

technical field [0001] The invention belongs to the technical field of industrial manufacturing automation, and in particular provides a method for an alarm limit self-learning system based on industrial process data, so as to intelligently correct the alarm limit in order to predict the production state more accurately in the production field. Purpose. Background technique [0002] In the current industrial manufacturing industry, the production process is very complicated, and various sudden production failures and errors are inevitable in the production process. In order to effectively capture and display this information, most of them have introduced computer monitoring systems. In the monitoring system Generally, a built-in alarm module is used to capture abnormal production information, provide warnings for production schedulers, and allow them to take timely measures to make reasonable adjustments to process equipment and production rhythms to avoid losses caused by p...
