Method and device for processing oil level curve data

Abstract

Embodiments of the present invention provide a method and device for processing oil level curve data. The method includes: reading the original oil level data of the current statistical cycle, and obtaining the first oil level data after preprocessing; combining the base oil level data with the first oil level data Combining the level data to obtain the second oil level data; removing and / or correcting the abnormal data in the second oil level data to obtain the third oil level data; The third oil level data is used to calculate the harmonic average, and the corresponding oil level harmonic average data points are obtained to obtain the fourth oil level data. The embodiment of the present invention makes the generated oil level curve smoother through the cleaning process of the numerical range and the cleaning process based on the mean value algorithm and the sliding window, and reduces the influence of individual abnormal values ​​on the generated curve; it is convenient for secondary analysis and more effective. It is beneficial to identify characteristic processes such as refueling, pumping and consumption.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a method and device for processing oil level curve data. Background technique [0002] The oil level sensor is a pressure sensor that measures the oil level. Based on the principle that the measured hydrostatic pressure is proportional to the height of the liquid. The static pressure is converted into an electrical signal, and then converted into a standard electrical signal after temperature compensation and linearity correction. The liquid level data collected and reported by the oil level sensor will fluctuate in a small range due to electromagnetic interference and sports driving interference. This kind of fluctuation generally fluctuates up and down within a reasonable range of the real liquid level, so it is difficult to distinguish. [0003] Due to economic cost considerations, most current oil level sensors do not have additional data storage space to store and...

And this kind of fluctuation generally fluctuates up and down within a reasonable range of the real liquid level, so it is difficult to distinguish

[0003] Due to economic cost considerations, most current oil level sensors do not have additional data storage space to store and process contextual oil level data. They simply process and report the currently collected analog signals, and do not calculate oil level data according to time series. Reasonability, even without filtering some obviously abnormal values
