Detailed Description

The inventor of the invention finds that the actually obtained indicator diagram is often not a regular convex multi-quadrangle, the process is very complicated by adopting a mode of calculating the area of the diagram by integration, the area of the indicator diagram is reduced, and the calculation of plastics is further influenced, so that the oil well yield measurement, the fault diagnosis of the oil pumping unit and the like are realized based on the area of the indicator diagram. In order to solve the problems in the prior art, the inventor provides an area division method for calculating the indicator diagram area, namely dividing the indicator diagram into a plurality of regular graphs, and calculating the areas of the regular graphs to obtain the indicator diagram area.

Referring to the schematic diagram of the indicator diagram shown in fig. 1, it should be noted that the points constituting the indicator diagram are not limited to the points given in fig. 1, and this embodiment is only described by taking this as an example, the inventor tries to divide the indicator diagram into a plurality of triangles, and since the indicator diagram is a closed graph generally composed of 144 points, the inventor selects any point as a vertex and connects it with other points, and can divide the indicator diagram into 152 triangles, and then, the areas of the 152 triangles are calculated according to a triangle calculation formula by using displacement data and load data of each point, and the areas of the 152 triangles are summed up, so that the area of the indicator diagram can be obtained.

However, since the indicator diagram is not necessarily a convex polygon, as the indicator diagram shown in fig. 1, the current indicator diagram is divided into graphs, and the obtained gray triangle part exceeds the indicator diagram, and the area of the indicator diagram obtained according to the above calculation method is larger than the area of the actual indicator diagram, that is, the area of the indicator diagram obtained by dividing the indicator diagram into a plurality of triangles is not accurate.

In order to quickly obtain the indicator diagram area, the inventor also proposes a Monte Carlo method (also translated into a Monte Carlo method) to obtain the indicator diagram area, wherein the Monte Carlo method is a numerical calculation method based on the theory and method of probability and statistics, and can be used for calculating the area of a region besides calculating the probability, such as randomly generating a plurality of points, and approximately calculating the indicator diagram area by the proportion of the points and all the points in the coverage range of the indicator diagram, but the actual experiment finds that the calculation efficiency of too many points is very low, and the approximate calculation is not the actual indicator diagram area, and a certain error exists, which affects the accuracy of specific application based on the indicator diagram area in each application scene.

After the above-mentioned various attempts, the inventor of the present invention continuously changes the angle of the straight line for dividing the indicator diagram, and finally finds that the graph division is performed on the indicator diagram by using a group of parallel lines parallel to the coordinate axis of the indicator diagram (for example, a group of parallel lines parallel to the load coordinate axis as shown in fig. 2), which does not exceed the area of the indicator diagram, so that the area of the indicator diagram is calculated more accurately by using the areas of the plurality of graphs obtained by the division, and the problem that the area of the indicator diagram calculated is inaccurate due to the vertex connection method and the monte carlo method which are described above and attempted by the inventor is solved.

Moreover, according to the dividing mode, the divided graphs are regular graphs, the area of the regular graphs can be rapidly and accurately calculated by directly utilizing a mathematical area calculation formula, the calculation amount of the area of the indicator diagram is greatly reduced, and the calculation efficiency and the calculation accuracy are improved compared with the traditional integral calculation method.

Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

Referring to fig. 3, a flowchart of an indicator diagram processing method provided in an embodiment of the present invention is shown, where the method may be applied to a computer device, such as a terminal device or a server with a computing function, and the embodiment does not limit a product type of the computer device, and may specifically include, but is not limited to, the following steps:

step S11, acquiring indicator diagram information;

in combination with the analysis of the above background art, the indicator diagram is generally a polygon surrounded by a plurality of points, and can represent the production condition of the oil field and the working state of the pumping unit, generally, one indicator diagram can be drawn for each stroke, and a large number of indicator diagrams will be obtained in the process of generating the oil field.

Therefore, the indicator diagram information acquired by this embodiment may at least include: the displacement data and the load data which correspond to a plurality of points forming the current indicator diagram respectively, namely the horizontal and vertical coordinate data of each point forming the current indicator diagram, are used for determining the position of each point, the relative position relationship between each point and the like.

It should be noted that the present embodiment does not limit how to acquire the displacement data and the load data of each point. In general, the displacement is related to the acquisition time interval of a load sensor of the pumping unit, and in one stroke, the displacement is divided according to the stroke and the acquisition time interval to obtain the corresponding displacement during each load return.

Step S12, dividing the current indicator diagram into a plurality of regular graphs by a group of parallel lines parallel to the coordinate axis of the current indicator diagram;

as described above in the analysis of the core idea of the embodiment of the present invention, in order to avoid that the divided graphs exceed the area of the current indicator diagram and reduce the workload of calculating the area of the indicator diagram, the embodiment may divide the current indicator diagram into a plurality of regular graphs by using a straight line parallel to the load coordinate axis, such as the indicator diagram division manner shown in fig. 2, but is not limited to the division manner shown in fig. 2.

Step S13, calculating the area of each regular pattern by using the displacement data and the load data of each point forming the regular pattern;

in this embodiment, the divided regular patterns may include regular quadrangles and triangles, the areas of the regular patterns generally have a general mathematical calculation formula, and the time taken for obtaining the areas by using the mathematical calculation formula is far shorter than the time taken for directly integrating the indicator diagram to obtain the areas.

When calculating the area of each graph, the corresponding parameter in the area calculation formula may be obtained by using the coordinate data of each vertex forming the graph, for example, for the transverse span, the difference between the displacement data of two vertices may be calculated, and the like.

In step S14, the areas of the plurality of regular patterns obtained are calculated to obtain the pattern area of the current indicator diagram.

In this embodiment, the manner of dividing the current indicator diagram adopted in the step S12 is different, the obtained regular patterns are different, and the method of calculating the area of the current indicator diagram by using the area of the obtained regular patterns is also different, which may specifically refer to the description of the corresponding embodiment below, and this embodiment is not described herein again.

In summary, in order to obtain the area of the current indicator diagram quickly and accurately, after the indicator diagram information is obtained, a set of parallel lines parallel to the coordinate axis of the indicator diagram is selected based on the displacement position relationship among a plurality of points forming the current indicator diagram, and the current indicator diagram is subjected to graph division, so that the obtained regular graph is prevented from exceeding the current indicator diagram, the area of the current indicator diagram obtained by calculation is ensured to be accurate by using the area of each regular graph, and the area of the regular graph can be obtained by directly using a simple area calculation formula without using an integral calculation, so that the calculation amount is greatly reduced, and the calculation efficiency and the accuracy are improved.

Further, the inventor of the present invention found that some acquired indicator diagrams have displacement symmetry characteristics, such as the indicator diagram shown in fig. 4, except for the maximum displacement point and the minimum displacement point in the indicator diagram, the displacement intervals of other adjacent moments are the same, and the displacements of two points symmetric up and down on the indicator diagram are the same, based on this characteristic, the inventor proposed that the intermediate displacement points except the maximum displacement point and the minimum displacement point are divided into (144-2-2)/2-70 quadrangles, the maximum displacement point and the minimum displacement point respectively form a triangle with the adjacent displacement points, that is, the indicator diagram is divided into two triangles and a plurality of quadrangles, and the areas of these regular graphs are calculated to obtain the areas of the indicator diagrams.

Specifically, referring to fig. 5, a schematic flow chart of an indicator diagram processing method according to another embodiment of the present invention is provided, where this embodiment mainly processes an indicator diagram (such as the indicator diagram shown in fig. 4) with displacement symmetry characteristics, and may specifically include, but is not limited to, the following steps:

step S21, acquiring indicator diagram information;

the indicator diagram information at least includes displacement data and load data corresponding to a plurality of points constituting the current indicator diagram.

Step S22, detecting the relationship among the displacement data of each intermediate displacement point forming the current indicator diagram, and determining a plurality of pairs of intermediate displacement points with the same displacement data in each intermediate displacement point;

wherein the intermediate displacement point is a point other than the minimum displacement point and the maximum displacement point constituting the current indicator diagram. The present embodiment may detect whether the current indicator diagram has the above-mentioned displacement symmetry characteristic by means of the step S22.

For the indicator diagram shown in fig. 4, by analyzing the displacement data of each intermediate displacement point constituting the current indicator diagram, it can be known that the displacements of the vertically symmetric intermediate displacement points are the same, and the displacement intervals at adjacent times are the same, which indicates that the intermediate displacement points are connected to form a quadrangle, and at least one set of opposite sides of the quadrangle are parallel, and the indicator diagram having the characteristics can be processed by adopting the graph division method described in this embodiment, so that the area of the indicator diagram can be calculated more quickly.

Alternatively, in this embodiment, the minimum displacement point and the maximum displacement point may be determined from a plurality of points that constitute the plurality of indicator diagrams by comparing displacement data of the points, and at this time, a point that constitutes the current indicator diagram except for the minimum displacement point and the maximum displacement point may be regarded as the intermediate displacement point. For convenience in describing the subsequent processing steps, two intermediate displacement points having the same displacement data may be referred to as a pair of intermediate displacement points, as shown in fig. 4, two upper and lower intermediate displacement points on one vertical line may be referred to as a pair of intermediate displacement points, and the current indicator diagram may be composed of a plurality of pairs of intermediate displacement points, a minimum displacement point, and a maximum displacement point.

And step S23, dividing the current indicator diagram into a plurality of quadrangles by using connecting lines between every pair of middle displacement points with the same displacement data, and forming a triangle by using the maximum displacement point and the minimum displacement point and the adjacent middle displacement points respectively.

Referring to fig. 4, for the indicator diagram with displacement symmetry characteristics, in addition to the triangle divided at the two ends of the indicator diagram, the middle area may be divided into several quadrangles, that is, according to the analysis of the characteristics of such indicator diagrams, a set of parallel lines parallel to the load coordinate axis (i.e., the connecting lines between the middle displacement points of each pair of displacement data) may be used to divide the current indicator diagram into a plurality of quadrangles, as in the above calculation manner, if the current indicator diagram is composed of 144 points, 70 quadrangles may be obtained according to the above division, and in some cases, the quadrangles may be parallelograms.

Moreover, for the maximum displacement point and the minimum displacement point in the current indicator diagram, two triangles may be formed with the middle displacement point having the same displacement data as the adjacent pair of displacement points, such as the triangles formed on the left and right sides in the indicator diagram of fig. 4.

It should be noted that, for the indicator diagram with displacement symmetry characteristic, the graph dividing manner described in this embodiment is not limited, and in general, if the overall shape of the resulting indicator diagram extends laterally, in the manner described in this embodiment, the graphical division may be performed by a set of parallel lines parallel to the load coordinate axis, if the overall shape of the resulting indicator diagram extends longitudinally, a set of parallel lines parallel to the axis of displacement coordinate may be used for graphical division, in which case there are multiple pairs of intermediate load points with the same load data as the intermediate load points of the indicator diagram, according to the graphical division concept of this embodiment, the indicator diagram can be divided into a plurality of quadrangles by using connecting lines between each pair of intermediate load points with the same load data, and a triangle is formed by the maximum load point and the minimum load point and the adjacent middle load point respectively.

Therefore, for different overall shapes of the obtained indicator diagrams, the graph division of the indicator diagrams is realized by utilizing the corresponding displacement symmetry characteristic or load symmetry characteristic and correspondingly adopting a group of parallel lines parallel to a load coordinate axis or a group of parallel lines parallel to a displacement coordinate axis to obtain a plurality of quadrangles and triangles, and the graph division flexibility and accuracy are improved. The determination of the overall shape of the indicator diagram may be based on a displacement data difference between a maximum displacement point and a minimum displacement point, and a load data difference between a maximum load point and a minimum load point, and the determination method is not limited in this embodiment.

Step S24, calculating the area of the corresponding quadrangle and the area of the corresponding triangle by using the displacement data and the load data of each point forming each quadrangle and each triangle;

still taking the indicator diagram shown in fig. 4 as an example, the triangle area is 1/2 (bottom x high), and x is used _i Indicating displacement data of the ith point, y _i Load data representing the ith point, triangle area S _{Triangle shape} ＝1/2[(y _i+1 -y _i )*(x _i+1 -x _i )]Square area S _{Quadrilateral shape} ＝(y _i+1 -y _i )*(x _i+1 -x _i ) In this embodiment, the area of each divided quadrangle and each divided triangle can be calculated by using the area calculation formulas of different figures, which is not described in detail.

And step S25, summing the areas of the plurality of quadrangles and the areas of the plurality of triangles to obtain the graphic area of the current indicator diagram.

In this embodiment, as shown in fig. 4, for the indicator diagram with displacement symmetry characteristics, the inner region of the indicator diagram is directly divided into a plurality of quadrangles and triangles in this embodiment, and compared with the way that the inventor originally thinks of dividing into a plurality of triangles, the regular graph obtained by dividing in this embodiment does not exceed the whole region of the indicator diagram, so that the areas of the plurality of regular graphs obtained can be directly summed to obtain the graph area of the current indicator diagram, which is simple and convenient, and the accuracy of the current indicator diagram area is ensured, and the calculation efficiency is improved. Compared with the traditional integral calculation mode, the method greatly improves the calculation efficiency and accuracy. As another embodiment provided by the present invention, in practical applications, the obtained indicator diagrams do not all have displacement symmetry characteristics, and for such indicator diagrams without displacement symmetry characteristics as shown in fig. 6, the graph division method and the indicator diagram area calculation method described in the above embodiments cannot be adopted, so that for such indicator diagrams, the inventor proposes an area difference method to calculate the area of the indicator diagram, and for the areas of two regions for performing difference calculation, the two regions may be divided into a plurality of trapezoids, the areas of the corresponding plurality of trapezoids are used to obtain the areas of the corresponding regions, and then the difference between the areas of the two regions is calculated to obtain the graph area of the indicator diagram.

Specifically, with reference to the graph dividing manner shown in fig. 6, referring to a flowchart of the indicator diagram processing method provided in another embodiment shown in fig. 7, the method may specifically include the following steps:

step S31, acquiring indicator diagram information;

Step S32, acquiring the maximum displacement point and the minimum displacement point which form the current indicator diagram;

step S33, dividing the current indicator diagram into a first line segment and a second line segment by taking the maximum displacement point and the minimum displacement point as critical points;

referring to the indicator diagram shown in fig. 6, the displacement data of the upper and lower points on the same vertical line are not the same, and the current indicator diagram cannot be processed according to the indicator diagram graph division method provided in the above embodiment.

Specifically, in this embodiment, the indicator diagram may be divided into an upper portion and a lower portion by the maximum displacement point, that is, the points constituting the indicator diagram are divided by using the minimum displacement point a and the maximum displacement point B as critical points, so as to form an upper line segment and a lower line segment, which are respectively marked as a first line segment and a second line segment, for example, the first line segment corresponding to the thick solid line and the second line segment corresponding to the thin solid line in fig. 6. At this time, the two line segments and the two coordinate axes, and the vertical line passing through the maximum displacement point may form two closed regions.

It should be noted that, in the present embodiment, for the indicator diagram shown in fig. 6, the overall shape extends transversely, and the first line segment and the second line segment, and the two line segments described in the upper section, are determined to be located in the respective regions in the manner shown in step S33; if the indicator diagram extends longitudinally in the overall shape, according to the concept of the present embodiment, the current indicator diagram may be divided into the third line segment and the fourth line segment distributed left and right by using the minimum load point and the maximum load point as the critical points.

Of course, the mode of dividing the indicator diagram in the present invention is not limited to the two implementation modes described above, and may be determined according to the characteristics of the actually obtained current indicator diagram based on the core concept described above, and the present invention is not listed here.

Step S34, dividing a first line segment, two coordinate axes of the current indicator diagram and a first area between the first straight lines into a plurality of first trapezoids by using a group of parallel lines parallel to the load coordinate axes, and dividing a second line segment, two coordinate axes and a second area between the first straight lines into a plurality of second trapezium coordinate axes;

wherein the first straight line is a straight line passing through the point of maximum displacement in the set of parallel lines parallel to the load coordinate axis, and the rightmost straight line is a straight line parallel to the load coordinate axis as shown in fig. 6.

Still taking the indicator diagram shown in fig. 6 as an example, as described above, the area where the first line segment located above (i.e., the area filled by the line segment at an acute angle to the displacement coordinate angle in fig. 6) is located covers the area where the second line segment located below (i.e., the area filled by the line segment at an obtuse angle to the displacement coordinate angle in fig. 6) is located. It should be noted that, when determining the two regions, it is also possible to use a vertical line passing through the minimum displacement point, if necessary.

For convenience of description, in this embodiment, the area between the first line segment, the two coordinate axes, and the first straight line may be referred to as a first area, the area between the second line segment, the two coordinate axes, and the first straight line may be referred to as a second area, and the two areas are distinguished by oblique lines with different angles in fig. 6.

As for any of the above-described regions, taking the first region as an example, as shown in fig. 8, the first region is divided into a plurality of trapezoids by connecting points on the displacement coordinate axis of the same displacement data as those on the first line segment, and each of the trapezoids in the first region shown in fig. 8 is referred to as a first trapezoid and each of the trapezoids in the second region is referred to as a second trapezoid in order to distinguish the trapezoids obtained by graphically dividing the first region from the second region.

It should be noted that the division manner of the current indicator diagram is not limited to the division manner described in the present embodiment, and as described above, the indicator diagram may be divided into a third line segment and a fourth line segment, in this case, a point on the load coordinate axis where the load is the same as that on the third line segment (i.e., the left line segment) may be connected, the third area and the fourth area obtained in the manner described in the present embodiment may be divided into a plurality of trapezoids, the division manner of the diagram is the same as the division manner described in the present embodiment, and the present embodiment is not described in detail herein.

Step S35, calculating the area of the corresponding first trapezoid and the area of the corresponding second trapezoid by using the displacement data and the load data of each point forming each first trapezoid and each second trapezoid;

still taking the indicator diagram shown in fig. 6 as an example, after the indicator diagram is graphically divided in the above manner, since the first region and the second region may both be composed of corresponding trapezoids obtained by division, the areas of the corresponding regions may be obtained by accumulating the areas of the corresponding trapezoids. According to the trapezoidal area calculation formula: s _{Trapezoidal shape} The area of each trapezoid can be calculated as 1/2 (top + bottom) high.

Refer to the coordinate data (x) of each vertex of a certain trapezoid shown in FIG. 8 _i ，y _i ) Combining the above trapezoid area calculation formula, the trapezoid area S can be obtained _{Trapezoidal shape} ＝1/2*(y _i +y _i+1 )(x _i+1 -x _i ),. According to the calculation mode, the area of each trapezoid in the two regions can be calculated, namely the area of each first trapezoid and the area of each second trapezoid are obtained.

Step S36, summing the obtained areas of the plurality of first trapezoids to obtain an area of a first region, and summing the obtained areas of the plurality of second trapezoids to obtain an area of a second region;

following the indicator diagram shown in fig. 6 given above, the area S of the first region _{First region} Or the area S of the second region _{Second region} It can be calculated according to the following formula:

and step 37, performing difference operation on the area of the first region and the area of the second region to obtain the graphic area of the current indicator diagram.

After the area of each region is obtained based on the above calculation method, as shown in fig. 6, the first region includes the current indicator diagram region and the second region, and therefore, the area of the second region subtracted from the area of the first region is the graph area of the current indicator diagram, i.e., S _{Indicator diagram} ＝S _{First region} -S _{Second region} 。

It can be seen that, in the present embodiment, for the indicator diagram without the displacement symmetry characteristic, a calculation mode of an area difference is adopted, the area of the current indicator diagram is quickly and accurately obtained, and in the obtaining process, the current indicator diagram is divided into a plurality of trapezoids, so that the area of the region is calculated, instead of adopting a triangle division mode, an integral calculation mode is not adopted, the efficiency and accuracy of indicator diagram calculation are improved, and further, the accuracy and efficiency of the analysis result of the subsequent application scene based on the obtained indicator diagram area are improved.

It should be noted that the area difference calculation method proposed in this embodiment is also applicable to the calculation of the indicator diagram area with displacement symmetry, but it cannot achieve the rapidity and accuracy of the graph division and indicator diagram area calculation method corresponding to fig. 4 and 5. Therefore, the area difference calculation method proposed in this embodiment can be applied to the calculation of the graphic areas of more indicator diagrams, that is, the application range is wider.

In summary, in the present invention, the indicator diagram with displacement symmetry characteristics can be divided into a plurality of quadrangles and triangles, and the graphic areas of the indicator diagram are obtained by summing the graphic areas; for the indicator diagram without displacement symmetry, the areas of the plurality of trapezoids divided by the divided different regions need to be summed to obtain the corresponding region area, and then the area difference between the two region areas is calculated to obtain the graph area of the current indicator diagram.

Therefore, for different types of indicator diagrams, different graphic division modes can be flexibly selected, the current indicator diagram is subjected to graphic division, after a plurality of regular graphic areas are obtained, the graphic areas of the indicator diagram are quickly and accurately obtained by adopting a summing or difference-solving mode, complex operation of integral is not needed, the calculation workload is greatly reduced, and the working efficiency and the accuracy are improved.

In addition, in practical application, because the indicator diagram area is an important basis for judging the working state of the pumping unit, after the current indicator diagram area is obtained according to the above modes, whether the pumping unit normally works can be judged according to the current indicator diagram area, of course, the working state of the pumping unit can be determined by utilizing the area change of a plurality of indicator diagrams obtained within a period of time, the petroleum development progress and the like can be determined according to the area change, and the obtained indicator diagram area can be further processed according to actual requirements.

In general, this embodiment may store the area of the current indicator diagram obtained each time, and when it is necessary to count the area change of the indicator diagram, may obtain the areas of a plurality of indicator diagrams obtained within a preset time from the current time to determine the area change of the plurality of indicator diagrams, and then obtain the meaning of the indicator diagram area change representation according to a preset judgment criterion.

It should be noted that, the present invention does not limit how the calculated graph area of the indicator diagram meets the application requirements in each application scenario, and a corresponding processing method may be determined according to actual needs, which is not described in detail herein in this embodiment.

Optionally, in practical applications of the foregoing embodiments, for some special reasons, sometimes the first point and the last point of the indicator diagram are not coincident, that is, sometimes the obtained current indicator diagram is not a closed graph, in this case, the present embodiment may manually supplement a last returning point to ensure that the last point and the first point are the same in position, that is, the displacement data and the load data are the same.

Therefore, on the basis of the foregoing embodiments, referring to a further schematic flow diagram of the indicator diagram processing method shown in fig. 9, after obtaining the current indicator diagram information, and before performing the step of determining the graph division rule of the current indicator diagram based on the relationship between the displacement data respectively corresponding to the multiple points, this embodiment may further include the following steps:

step S41, obtaining displacement data and load data of a first point and a last point which form the current indicator diagram;

the present embodiment may determine the first point and the last point constituting the current indicator diagram according to the generation time of each point of the indicator diagram, but is not limited to this determination.

step S44, dividing the current indicator diagram into a plurality of regular graphs by a group of parallel lines parallel to the coordinate axis of the current indicator diagram;

optionally, in practical application, each time an indicator diagram is generated, the indicator diagram may be output, and a worker may visually see whether the indicator diagram is a closed diagram, and if not, may manually make up points in time, so that the computer device may obtain coordinate data of the make-up points input by the user in time, and update the indicator diagram information.

Of course, in this embodiment, the computer device may also compare the coordinate data of the first point and the last point of the current indicator diagram to determine whether the two points are overlapped, if not, output a prompt message to remind the operator to perform point compensation, and update the indicator diagram information of the current indicator diagram by using the obtained coordinate data of the point compensation.

Step S45, calculating the area of each regular graph by using the displacement data and the load data of each point forming each regular graph;

and step S46, calculating areas of the obtained plurality of regular patterns to obtain the pattern area of the current indicator diagram.

In addition, referring to the flowchart shown in fig. 10, in combination with the two indicator diagram dividing methods proposed in the foregoing embodiment and the description of the corresponding indicator diagram area calculating method, in a general case, the indicator diagram has a displacement symmetry characteristic, a plurality of quadrangles can be obtained from the middle displacement point of the indicator diagram in the manner described in the foregoing alternative embodiment, and then the area of the indicator diagram is obtained by calculation.

Optionally, as for the obtained indicator diagram, a special situation as shown in fig. 11a may also occur, which is often a case where a pump of the pumping unit has a serious fault or other problems, resulting in a serious abnormality of the obtained current indicator diagram, where the current indicator diagram often appears as shown in fig. 11a, and for convenience of research on the current indicator diagram, the obtained indicator diagram may be simplified into the indicator diagram shown in fig. 11 b.

Based on the above, after the graph area of the current indicator diagram is calculated according to the above method, whether the graph area is a negative value or not can be judged, and if the graph area is the negative value, fault prompt information can be output to inform workers that the oil pumping unit or other equipment has faults at the moment and needs to be overhauled.

Certainly, this embodiment can be through a large amount of experiments, the indicator diagram area of each negative value, the corresponding beam-pumping unit trouble condition of predetermining, like this, when detecting the graphic area of current indicator diagram and being the negative value, can confirm what rank trouble is to present beam-pumping unit according to the corresponding relation that prestores to determine the beam-pumping unit of serious fault from this, inform the staff to overhaul it, solve the beam-pumping unit participation work of trouble, influence work efficiency, reduce the oil pumping volume etc..

In summary, after the current indicator diagram information is obtained, according to the displacement characteristics of the current indicator diagram, the corresponding graph division rule is selected, the current indicator diagram is subjected to graph division, and then the areas of the plurality of divided graphs are subjected to simple mathematical operation, so that the graph area of the current indicator diagram can be obtained, an integral mode is not required, and the calculation efficiency, the accuracy and the flexibility are improved.

In addition, in the process of dividing the current indicator diagram into graphs, the present embodiment does not adopt a triangle division mode proposed by earlier research of the inventor, but adopts a quadrilateral division mode or a quadrilateral + triangle division mode, so that the problem that the area of the obtained graph is larger than the area of the actual indicator diagram due to the fact that the current indicator diagram is directly divided by triangles is solved, and the accuracy of calculating the area of the indicator diagram is improved.
