AI Technical Summary

Technical Problem

In the existing technology, oil leakage problems in coil-type equipment are difficult to detect in a timely manner. Manual inspection is inefficient and prone to subjective misjudgment. Existing detection devices are costly and not easy to widely implement.

Method used

The monitoring equipment regularly captures images of coil-type equipment, and determines whether the oil level and oil temperature exceed the normal range by observing changes. After multiple confirmations, the terminal host performs intelligent diagnosis and issues warnings. The monitoring equipment is shared with existing surveillance camera equipment, reducing construction and costs.

Benefits of technology

It enables timely and accurate early warning of oil leak risks, reduces construction complexity and costs, and improves the timeliness and accuracy of oil leak detection.

Abstract

The invention discloses a coil type equipment oil leakage detection method and device, and relates to the technical field of oil leakage detection, and the method comprises the steps: carrying out the photographing and sampling of the oil level and oil temperature of coil type equipment through monitoring equipment, and recording the oil level and oil temperature as reference values; regularly shooting images of the coil equipment; oil volume and temperature changes are judged according to the image of the coil type equipment, a normal oil level range is determined, and early warning is given out when the normal oil level range is exceeded; if the oil level exceeds the normal range, collecting for at least three times to confirm abnormity; after frequent confirmation, taking the oil level and the oil temperature after abnormity as references for retesting, and if abnormity occurs again, judging that the fault is an oil leakage fault; the oil leakage risk of the equipment can be informed in time, the risk can be accurately diagnosed, and the method has a good application effect in the aspects of timeliness and accuracy. The problems that manual inspection is not timely, and subjective misjudgment exists in defect discovery are fully solved.
