Mechanical equipment vibration alarm information pushing method

Abstract

A mechanical equipment vibration alarm information pushing method comprises the following steps: 1, collecting a vibration signal, and determining whether mechanical equipment vibration needs to be alarmed or not according to a vibration alarm threshold value; step 2, judging the relationship between the vibration magnitude vib obtained in the step 1 and the vibration magnitude previb which is previously triggered to give an alarm and pushed; step 3, judging whether the time difference between the acquisition timestamp ts corresponding to the vibration vib and the acquisition timestamp prets corresponding to the vibration magnitude previb which is previously triggered to give an alarm and pushed is greater than or equal to a set timing pushing time interval threshold value or not, and judging whether the alarm triggered in the step 1 needs to be pushed to an alarm receiver or not. According to the alarm pushing method provided by the invention, the focusing degree and attention of thealarm information are effectively improved, and the problem of alarm storm is effectively solved. Through the application of the invention, the effective purification and filtering of the vibration alarm information of the mechanical equipment can be realized, the alarm data with more attention and analysis can be pushed, the alarm pushing amount is reduced, and the alarm accuracy is effectively improved.

Description

technical field [0001] The invention belongs to the field of mechanical equipment state monitoring and predictive maintenance, and in particular relates to a method for pushing vibration alarm information of mechanical equipment. Background technique [0002] Among the mechanical equipment failures, the failures caused by excessive vibration account for a very high proportion. Vibration is an important factor affecting the safe and stable operation of mechanical equipment. Vibration can directly reflect the health status of machinery and equipment, and is an important indicator for the safety assessment of machinery and equipment. When a unit is running normally, its vibration value and vibration change value should be relatively small and stable. Once the vibration value of the unit becomes large, or the vibration becomes unstable, it indicates that the equipment has a certain degree of failure. Therefore, it is very necessary to monitor and warn the vibration in the vibr...

AI Technical Summary

Problems solved by technology

In the field of mechanical equipment status monitoring, the use of this alarm method will cause the alarm receiver to fall into an "alarm storm". The receiver can not distinguish the key data from the excessive number of alarms received, and finally cannot effectively focus on the alarm data that needs attention. As a result, it is impossible to understand the abnormal state of mechanical equipment in time, and the best time window for maintenance of mechanical equipment is missed, causing safety problems
