AI Technical Summary

Technical Problem

In existing technologies, the accuracy of monitoring and identifying abnormal fuel consumption of construction machinery equipment during operation is low, making it difficult to accurately identify abnormal fuel consumption.

Method used

By acquiring the measured return oil pressure value and engine parameters of the construction machinery equipment, the calibrated value of the return oil pressure is determined. Based on the comparison results between the difference and the threshold range, combined with the difference between the measured fuel consumption value and the theoretical fuel consumption value, it is possible to identify whether the fuel consumption in the fuel tank is abnormal.

Benefits of technology

It enables accurate identification of abnormal fuel consumption in the working state of construction machinery and equipment, improving the accuracy and comprehensiveness of fuel consumption monitoring.

Abstract

The disclosure provides an oil consumption monitoring method, device, system and engineering machinery equipment, and relates to the technical field of engineering machinery equipment. The oil consumption monitoring method comprises the following steps: obtaining an oil return pressure measurement value of an oil tank of an engineering machinery equipment in a working state and an engine parameter of the engineering machinery equipment; determining an oil return pressure calibration value corresponding to the engine parameter according to the engine parameter of the engineering machinery equipment; and determining whether the fuel consumption in the oil tank is abnormal according to a comparison result of a difference between the oil return pressure measurement value and the oil return pressure calibration value and a first threshold range. Through the above method, the abnormal oil consumption condition of the whole machine during work can be accurately identified.
