Accordingly, unless otherwise indicated, features of the various embodiments may be additionally combined, separated, interchanged, and/or rearranged without departing from the technical concept of the present disclosure.

The use of cross-hatching and/or shading in the drawings is generally used to clarify the boundaries between adjacent components. As such, unless otherwise noted, the presence or absence of cross-hatching or shading does not convey or indicate any preference or requirement for a particular material, material property, size, proportion, commonality between the illustrated components and/or any other characteristic, attribute, property, etc., of a component. Further, in the drawings, the size and relative sizes of components may be exaggerated for clarity and/or descriptive purposes. While example embodiments may be practiced differently, the specific process sequence may be performed in a different order than that described. For example, two processes described consecutively may be performed substantially simultaneously or in reverse order to that described. In addition, like reference numerals denote like parts.

When an element is referred to as being "on" or "on," "connected to" or "coupled to" another element, it can be directly on, connected or coupled to the other element or intervening elements may be present. However, when an element is referred to as being "directly on," "directly connected to" or "directly coupled to" another element, there are no intervening elements present. For purposes of this disclosure, the term "connected" may refer to physically, electrically, etc., and may or may not have intermediate components.

For descriptive purposes, the present disclosure may use spatially relative terms such as "below … …," below … …, "" below … …, "" below, "" above … …, "" above, "" … …, "" higher, "and" side (e.g., "in the sidewall") to describe one component's relationship to another (other) component as illustrated in the figures. Spatially relative terms are intended to encompass different orientations of the device in use, operation, and/or manufacture in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as "below" or "beneath" other elements or features would then be oriented "above" the other elements or features. Thus, the exemplary term "below … …" can encompass both an orientation of "above" and "below". Further, the devices may be otherwise positioned (e.g., rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

As shown in fig. 1, a method S100 for echo correction of a fill-level measuring device comprises:

s102: obtaining a reflected echo signal measured by a level measuring device;

s104: judging whether the reflected echo signal needs to be corrected or not;

s106: selecting a preset correction mode according to the reflected echo signal under the condition that the reflected echo signal needs to be corrected;

s108: and correcting the reflected echo signal according to the selected preset correction mode so as to obtain a corrected echo signal, wherein in the corrected echo signal, the noise signal in the reflected echo signal is eliminated or reduced.

And the method also comprises amplitude operation correction, wherein in the amplitude operation correction, the amplitude of the reflected echo signal is corrected, and/or the amplitude of the corrected echo signal is corrected so as to at least reduce the amplitude of the noise signal.

Wherein, in the amplitude calculation correction,

In the corrected echo signals, the reduction amplitudes of the noise signals at different positions are different, and the amplification amplitudes of the calculated echo signals at different positions are different.

The preset noise modification curve is a continuous curve or a curve formed by connecting different straight line segments or curve segments.

And in the process of editing the preset noise modification curve, determining an editing point, modifying the amplitude of the editing point, and connecting the editing points with modified amplitudes to form a modified noise modification curve.

The method comprises the steps of editing a preset noise modification curve, determining the amplitudes of partial editing points in the process of editing the preset noise modification curve, enabling the amplitudes of the partial editing points to be in the same horizontal position, and connecting the partial editing points to form the noise modification curve.

The method comprises the following steps of calculating and editing a preset noise modification curve, selecting more than two preset curves in the process of calculating and editing the preset noise modification curve, and performing mutual calculation on the selected preset curves to form the noise modification curve.

And during the amplitude editing and correction, determining the corresponding modified signal amplitudes one by one for the reflected echo signals.

The amplitude editing and correcting method comprises the steps of determining corresponding modified signal amplitudes of partial signals of the reflected echo signals, wherein the partial signals are signals at the same horizontal line position, and the modified signal amplitudes of other signals at the same horizontal position are determined based on the modified signal amplitudes corresponding to the partial signals.

Wherein, judge whether reflection echo signal needs the correction, including judging through whether triggering condition satisfies, triggering condition includes: more than one of the amplitude of the reflected echo signal, the position of the reflected echo signal, the amplitude of the noise and the position of the noise reaches the trigger threshold value corresponding to each.

Further, the parameters related to the trigger condition may also be changed according to external conditions, such as the amplitude or length of the noise modification curve.

As shown in fig. 2, after the echo curve is modified by the noise modification curve, a modified echo curve is obtained. The correction may be addition or subtraction of the echo curve with a plurality of such noise correction curves once or a plurality of times, or may be multiplication or division of the echo curve with a plurality of such noise correction curves once or a plurality of times. The starting point of the echo curve may not be the entire measurement range, and may be a certain part or several parts of the measurement range. The noise modification curve may also be a replica of some short-time echo curve or a part of the echo curve after modification. The echo curve can be operated with the noise modification curve to obtain a new echo curve, the effect is that the noise signal of the empty tank curve or the non-echo part becomes simple or smooth, or level, or is reduced, or the echo signal can be more easily identified in the noise when the echo signal is at different distances, and finally the amplitude of the echo signal is more stable. Specifically, the noise reduction at different distances is different in amplitude, and the signal increase in amplitude or amplification factor is different in different regions. The noise reduction amplitude may be a curve with distance, may be a plurality of straight lines or a plurality of connected line segments or curve segments.

As can be seen from fig. 2 and 3, the echo correction method provided by the present invention can make the echo correction mode flexible and diverse, and is convenient for a user to select an appropriate correction mode according to actual needs, so as to achieve a denoising effect suitable for different application occasions, and make the amplitude of the corrected echo signal more stable and have strong usability.

As shown in fig. 3, the amplitude editing and correcting method for correcting the echo curve or the noise modifying curve may be a method of setting the position and the amplitude point by point, moving the point by point up and down and left and right to determine the point, and then connecting a plurality of points to form a line. For different points on the horizontal line, only a part of the points may be edited, such as editing one point or two points, thereby reducing one editing point, and then connecting the lines by a plurality of points.

As shown in fig. 4, an echo signal processing method S200 includes:
