Problems solved by technology

[0003] However, in the process of detecting the vibration state of rolling mills in the iron and steel industry, due to the existence of rolling processes, the amplitude of the root mean square index will increase during rolling, which will trigger the monitoring threshold of the characteristic indicators, often resulting in the rolling process. Causes a large number of false alarms, reduces the effectiveness of vibration alarms, and increases the workload of diagnostic engineers and on-site staff

Abstract

The invention discloses a device-based vibration signal alarm identification method and a computing device. The method is suitable for being executed in the computing device. The method includes the following steps that: the vibration signals of a device at a current time point are collected, and a root mean square index amplitude corresponding to the vibration signals is calculated; whether the root mean square index amplitude exceeds a preset first real-time threshold is judged; if the root mean square index amplitude exceeds the preset first real-time threshold, a rotation speed, a gear failure index, a bearing failure index and a power frequency failure index corresponding to the vibration signals are obtained; whether the rotation speed, the gear failure index, the bearing failure index and the power frequency failure index all meet their respective invalid alarm states is judged; if the rotation speed, the gear failure index, the bearing failure index and the power frequency failure index all meet their respective invalid alarm states, it is determined that the state of the device is normal, and no alarm signals are issued, otherwise, it is determined that the state of the device is abnormal, and alarm signals are issued.

Description

Technical field [0001] The invention relates to the field of equipment monitoring, in particular to a vibration signal alarm recognition method based on equipment and a computing device. Background technique [0002] In the field of equipment condition monitoring, currently, monitoring indicators are mainly obtained from the collected vibration signals, and monitoring thresholds are set for the indicators. When the amplitude of the collected vibration signals exceeds a predetermined threshold, a vibration alarm is triggered. At present, when detecting the vibration state of equipment, it mainly relies on the root mean square (RMS: Root Mean Square) index amplitude, that is, the root mean square value extracted from the vibration signal. It is a relatively classic vibration index, which can More effective response to the magnitude of vibration. [0003] However, in the process of detecting the vibration state of rolling mills in the steel industry, due to the rolling process, the a...
