Abstract

The invention discloses a device state detection method. The method is executed in a computing device and method includes the following steps that: the vibration signals of a device to be tested in aplurality of unit time periods during a current detection interval are acquired, and the vibration time-domain waveforms of each unit time period are determined according to the vibration signals; thepositive envelope waveforms of the vibration time-domain waveforms of each unit time period are determined; the time-domain indexes and frequency-domain indexes of the device to be tested in the unittime periods are determined according to the positive envelope waveforms; and the time-domain index and frequency-domain index of the device to be tested during the current detection interval are determined according to the time-domain indexes and frequency-domain indexes of the device to be tested in the unit time periods; and the state of the device to be tested is determined according to the comparison results of the time-domain index and frequency-domain index of the device to be tested during the current detection interval and the time-domain index and frequency-domain index of the device to be tested during the previous detection interval, and the comparison results of the time-domain index and frequency-domain index of the device to be tested and the time-domain indexes and frequency-domain indexes of other devices. The present invention also discloses a corresponding computing device.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment health management and fault diagnosis, in particular to an equipment state detection method and a computing device. Background technique [0002] Whether industrial production can be carried out efficiently depends to a large extent on whether the mechanical equipment in the production system can operate safely and stably without interruption. Therefore, it is necessary to detect the health status of each mechanical equipment in the production system. [0003] Existing equipment status detection usually includes real-time monitoring and periodic detection. The real-time monitoring solution monitors the vibration amplitude of the equipment. When the vibration amplitude exceeds a certain threshold, an alarm is issued. The engineer will verify the fault and judge whether the equipment needs to be repaired. For the regular inspection plan, the engineer will give the health status and ma...
