Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is further described in detail below with reference to fig. 1-8 and the embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

The embodiments of the present invention will be described in further detail with reference to the drawings attached hereto.

Example 1:

referring to fig. 1, an embodiment of the present invention provides a method for monitoring production of corrugated cardboard, and a main flow of the method for monitoring production of corrugated cardboard is described as follows:

step 100: and acquiring initial test parameter information and initial warping degree information.

The initial test parameter information is parameter information that can be adjusted and is involved in the first test, for example: temperature, roller speed, humidity, glue amount, etc. The acquisition mode is obtained by inputting in advance, that is, before the test is started, the worker performs operation control according to the specified test parameters, and it should be noted that, if necessary, the worker performs measurement on some measurable data in the middle of the test, for example: the temperature may be measured by a thermometer. The primary warping degree information is information on the warping degree of the corrugated board produced after the test is performed according to the primary test parameter information, and in the present embodiment, the warping degree information is a positive value when the corrugated board is warped from the lower side to the upper side, and the warping degree information is a negative value when the corrugated board is warped from the upper side to the lower side. The acquisition mode can be any one of measurement modes, such as a warp gauge.

Step 101: and performing matching analysis according to the adjustment direction, the first test parameter information and the first warping degree information stored in the preset direction database to determine the adjustment direction corresponding to the first test parameter information and the first warping degree information, and defining the adjustment direction as the first adjustment direction information.

The initial adjustment direction information is the direction which needs to be adjusted and is judged according to the initial test parameter information, and the adjustment direction corresponding to each parameter is included. For example, if the lower surface is warped from the lower surface to the upper surface, the moisture content of the lower surface may be lower than that of the upper surface, and the adjustment direction may be such that the upper surface is preheated more and the moisture content is reduced, or the lower surface is preheated less and the moisture content is increased. The direction database stores the mapping relation between the initial adjustment direction information and the initial warping degree information, and in the database, the judgment can be carried out only by the positive and negative values of the warping degree information. The database is supported by the staff in the field according to the past experience and the experimental data and is input into the database. And when the initial warping degree information is obtained, the system automatically calls corresponding adjusting direction information from the database.

Step 102: and randomly selecting one parameter in the initial test parameter information to perform random adjustment according to the initial adjustment direction information.

After the adjustment direction information is determined, it indicates that adjustment is needed, and since the size of the amount to be adjusted is not known in the initial adjustment, the adjustment is performed arbitrarily, and it should be noted here that the adjustment range is within a reasonable range that meets the economic benefits of the production line.

Step 103: and acquiring secondary test parameter information and secondary warping degree information.

The secondary test parameter information is the information of the parameter after one parameter in the arbitrarily selected primary test parameter information is arbitrarily adjusted according to the primary adjustment direction information. The secondary warping degree information is information of the warping degree of the corrugated board produced after the production line equipment is set according to the secondary test parameter information. The obtaining method is consistent with step 100, and is not described herein.

Step 104: and judging whether the secondary warping degree information is preset leveling information or not.

The leveling information is information that the measured corrugated cardboard is flat, for example, the measured heights are all consistent. The judgment mode is numerical comparison.

Step 1041: and if the secondary warping degree information is leveling information, outputting and recording the secondary test parameter information as leveling parameter information.

If the secondary warping degree information is the flat information, the corrugated board is a flat board and meets the requirements, and the corrugated board does not need to be adjusted again. The leveling parameter information is information of a flat paperboard produced by the corrugated paperboard when the corrugated paperboard is output according to the parameter.

Step 1042: and if the secondary warping degree information is not the leveling information, calculating the proximity degree information according to the leveling information, the primary warping degree information and the secondary warping degree information.

The approach degree information is information of the degree of approach this time calculated from the secondary warping degree information. If the secondary warping degree information is not flat information, the secondary warping degree information does not meet the requirements at the moment, adjustment is needed to be continued, adjustment is carried out according to the proximity degree information, the warping degree information obtained through theoretical calculation can be close to the flat information, efficiency is high, and accuracy is high.

Step 105: and calculating the predicted adjustment parameter information according to the primary test parameter information, the secondary test parameter information and the proximity information.

The predicted adjustment parameter information is calculated according to the proximity information and the parameters of the two tests, namely, when the predicted adjustment parameter information is set according to the parameters, the corrugated board with the warping degree information close to the flatness information can be theoretically produced.

Step 106: and performing matching analysis according to the parameter range stored in the preset range database and the predicted adjustment parameter information to determine the parameter range corresponding to the predicted adjustment parameter information, and defining the parameter range as reasonable parameter range information.

The reasonable parameter range information is a reasonable range value of the parameter to be adjusted, and is influenced by the economic benefit of the production line and the conventional implementation means. The range database stores the mapping relation between the reasonable parameter range information and the predicted adjustment parameter information, and is a result obtained by workers in the field according to common knowledge and multiple economic benefit tests. When the predicted adjustment parameter information is calculated, the system automatically extracts the type of the parameter from the information, and then selects a corresponding reasonable range from the database according to the type of the parameter.

Step 107: and judging whether the predicted adjustment parameter information exceeds the parameter range information.

The purpose of the judgment is to determine whether the adjustment can be performed according to the expected adjustment parameter information.

Step 1071: if not, adjusting the corresponding parameters according to the predicted adjustment parameter information and continuously judging whether the parameters are leveling information or not.

If the parameter does not exceed the preset range, the parameter is adjusted according to the predicted adjustment parameter information, and the parameter does not exceed the reasonable range of the parameter, and the parameter can be adjusted according to the parameter. However, since the predicted adjustment parameter information is a theoretical value, it is necessary to perform a re-judgment and a re-adjustment.

Step 1072: if the parameter exceeds the preset threshold value, the corresponding parameter is adjusted according to the critical value of the parameter range information, another parameter is adjusted randomly according to the initial adjustment direction information, and then whether the parameter is the leveling information is judged continuously.

The parameter range information includes a range of values of the parameter, having a critical value. If the parameter exceeds the preset value, the parameter is not adjusted according to the predicted adjustment parameter information, the parameter can be adjusted to a critical value to enable the corrugated board to be closer to a flat state, and then another parameter needs to be adjusted to enable the corrugated board to be continuously flat.

Referring to fig. 2, the primary warp degree information, the secondary warp degree information, and the flatness information are collectively referred to as warp degree information, and the warp degree information measuring method includes:

step 200: the method comprises the steps of obtaining longitudinal angle curve information when a sliding roller moves along the conveying direction of the corrugated board and transverse angle curve information when the sliding roller moves perpendicular to the conveying direction of the corrugated board, wherein the longitudinal angle curve information comprises longitudinal position information of the sliding roller on the corrugated board and included angle information between a supporting rod of the sliding roller and the vertical direction, and the transverse angle curve information comprises transverse position information of the sliding roller on the corrugated board and included angle information between the supporting rod of the sliding roller and the vertical direction.

The longitudinal angle curve information is the information of the curve of the rotating angle change of the supporting rod on the sliding roller when the sliding roller moves along the conveying direction of the corrugated board, namely after the corrugated board is discharged according to the specified length, the sliding roller moves on the upper side and the lower side of the corrugated board and is always abutted against the corrugated board, and the sliding roller can not influence the warping degree of the corrugated board due to the fact that the sliding roller is light. The information contains a graph formed by the angle and the position of the slide roller during the movement, namely the warping degree of the point can be obtained through the position, and the information can be obtained by any angle measuring device, such as an optical theodolite. The transverse angle curve information is information of a curve of the rotation angle change of the supporting rod on the sliding roller when the sliding roller moves in the direction vertical to the conveying direction of the corrugated board.

Step 201: and analyzing the highest point and the lowest point in the curve according to the longitudinal angle curve information, defining the highest point as longitudinal maximum height information, and defining the lowest point as longitudinal minimum height information.

The longitudinal maximum height information is a point with the maximum height corresponding to a point with the maximum rotation angle amplitude in the longitudinal angle curve information, and can be obtained by calculation according to the angles of the support rods at two positions and the length of the support rods. The longitudinal minimum height information is a point with the maximum height corresponding to a point with the minimum rotation angle amplitude in the longitudinal angle curve information, and can be obtained by calculation according to the angles of the support rods at two positions and the length of the support rods.

Step 202: and analyzing the highest point and the lowest point in the curve according to the transverse angle curve information, defining the highest point as transverse maximum height information, and defining the lowest point as transverse minimum height information.

The horizontal maximum height information, the horizontal minimum height information, the vertical maximum height information, and the vertical minimum height information are similar, and are not described herein again.

Step 203: and calculating longitudinal difference information according to the longitudinal maximum height information and the longitudinal minimum height information.

The longitudinal direction difference information is information of a difference between the longitudinal direction maximum height information and the longitudinal direction minimum height information, and represents the degree of warpage of the corrugated board to a certain extent.

Step 204: and calculating the transverse difference information according to the transverse maximum height information and the transverse minimum height information.

The longitudinal difference information is information of a difference between the transverse maximum height information and the transverse minimum height information, and represents the degree of warpage of the corrugated board to a certain extent.

Step 205: and judging whether the longitudinal difference information and the transverse difference information are both 0 or not.

The purpose of the judgment is to determine whether the corrugated cardboard is flat or not.

Step 2051: if yes, outputting the leveling information.

If the two curves are both 0, the two curves are both flat curves, and the sliding rollers in the two directions do not move up and down, so that the corrugated board is flat.

Step 2052: if not, defining the longitudinal difference information or the transverse difference information which is not 0 as the warping degree information.

If the difference values are not all 0, the occurrence of the warping is only possible in one direction due to the characteristics of the corrugated board, and therefore, one difference value is 0 inevitably, and the other difference value is not 0, the difference value which is not 0 is defined as warping degree information, and the warping degree information has a certain reference value.

Referring to fig. 3, if there is warp degree information, the method for arbitrarily selecting one parameter of the initial test parameter information to arbitrarily adjust according to the initial adjustment direction information includes:

step 300: and acquiring relative position information corresponding to information which is not 0 in the longitudinal maximum height information or the transverse maximum height information.

The relative position information is information of a position on the corrugated cardboard corresponding to a height other than 0 out of the longitudinal maximum height information or the lateral maximum height information. The obtaining method is the same as that of step 201 and step 202, and is not described herein again.

Step 301: and performing matching analysis according to the warpage type and the relative position information stored in the preset warpage type database to determine the warpage type corresponding to the relative position information, and defining the warpage type as warpage type information.

The warp type information is information of the shape of the corrugated cardboard after the occurrence of the warp. The mapping relation between the warping type information and the relative position information is stored in the warping type database, and is obtained and stored by workers in the field according to the working experience of the workers. That is, the warp type information can be accurately determined according to the data of the longitudinal maximum height information or the transverse maximum height information and the difference of the positions of the maximum points, for example: the maximum height information in the longitudinal direction is not 0, and the maximum height information is located on both sides, which indicates that the warpage type is bending in the longitudinal direction.

Step 302: and performing matching analysis according to the influence parameters stored in the preset influence database and the warping type information to determine the influence parameters corresponding to the warping type information, and defining the influence parameters as the influence parameter information.

The influence parameter information is information of a factor influencing the occurrence of warpage, that is, the parameter is a parameter having the largest influence effect when the adjustment range is small. The influence database stores the mapping relation between the warping type information and the influence parameter information, and is obtained by workers in the field according to common knowledge and working experience. Namely, after the user inputs the warping type information, the system automatically calls out the corresponding influence parameter information from the database.

Step 303: and randomly selecting one parameter in the influence parameter information to perform random adjustment according to the initial adjustment direction information.

The selected parameters are influence parameter information, so that warping is easier to correct, the situation that the effect is not large and the number of times of adjustment is more is avoided, and the efficiency of the adjustment test is improved.

Referring to fig. 4, if the longitudinal difference information and the lateral difference information are not both 0, the method of defining the longitudinal difference information or the lateral difference information, which is not 0, as the warp degree information includes:

step 400: and judging whether the warping type information is transversely downwards bent or longitudinally downwards bent.

The purpose of the judgment is to determine the direction of the warpage and whether the highest point of the warpage is on the middle side.

Step 4001: and if the position is bent transversely or longitudinally, calculating adjacent positions according to the relative position information and preset spacing distance information, and defining the adjacent positions at two sides as first front adjacent position information and first rear adjacent position information.

The first front adjacent position information and the first rear adjacent position information are information of positions near the relative position information at a distance information from the relative position information, and two adjacent positions near the relative position information, and the first front adjacent position information and the first rear adjacent position information are only for distinguishing the two positions, and do not specify the front-rear direction, and may be arbitrarily specified, for example, the front is in the conveyor belt direction and the rear is in the conveyor belt conveying direction. If the bending is transverse downward bending or longitudinal downward bending, the highest point of the bending is in the middle side.

Step 4002: and if the first front adjacent position information and the first back adjacent position information are not bent transversely or longitudinally, judging whether the first front adjacent position information and the first back adjacent position information are longitudinal maximum height information or transverse maximum height information.

If the corrugated board is not bent downwards in the transverse direction or in the longitudinal direction, the middle side point of the corrugated board is the longitudinal minimum height information or the transverse minimum height information, and the purpose of judgment is to determine whether the corrugated board is a sharp point or not.

Step 401: and judging whether the first front adjacent position information and the first back adjacent position information are longitudinal minimum height information or transverse minimum height information.

Step 4011: if yes, the information is output as the wrinkle information.

The wrinkle information is information that the corrugated board has wrinkles, and can be output for character display, namely characters with the characters of the words of the wrinkles are displayed on the display screen. The warping is a gradual bending, when the middle side is the highest point, the heights of the two sides are gradually reduced, if the first front adjacent position information and the first rear adjacent position information are the minimum points, the other parts outwards are the longitudinal minimum height information or the transverse minimum height information, the other parts are in a flat state, the middle position is a raised high point, the abnormal condition is provided, and the abnormal condition is a wrinkle on the corrugated board.

Step 4012: if at least one is not, the longitudinal difference information or the lateral difference information other than 0 is defined as the warp degree information.

If at least one of the two sides is not the same, the two sides can be reduced continuously, the transition stage is shown here, the process is a gradual change process, and due to the characteristics of the corrugated board, the longitudinal difference information or the transverse difference information which is not 0 is defined as the warping degree information under the condition that the corrugated board is warped here.

Step 4021: if yes, the information is output as damage information.

The breakage information is information that the corrugated board has breakage, and can be output for character display, namely characters with the characters of breakage are displayed on the display screen. The warping is a gradual bending, when the middle side is the lowest point, the heights of the two sides are gradually increased, if the first front adjacent position information and the first rear adjacent position information are the maximum points, the other parts outwards are longitudinal maximum height information or transverse maximum height information, the other parts are flat at the moment, the place at the place is a sunken point, the place is an abnormal situation, and the abnormity is broken on the corrugated board.

Step 4022: if at least one is not, the longitudinal difference information or the lateral difference information other than 0 is defined as the warp degree information.

If at least one of the two sides is not the same, the two sides can be increased continuously, the transition stage is shown here, the process is gradually changed, and due to the characteristics of the corrugated board, the longitudinal difference information or the transverse difference information which is not 0 is defined as the warping degree information under the condition that the corrugated board is warped here.

Referring to fig. 5, if the longitudinal difference information and the lateral difference information are both 0, the method of outputting the leveling information includes:

step 500: and acquiring damping information of an induction roller moving along the circumferential direction of the corrugated board, wherein the induction roller vibrates up and down along the vertical direction, and the damping information comprises upper damping information and lower damping information.

The damping information is information of damping caused by collision between the upper and lower end portions of the induction roller, and may be pressure information or touch information. When the longitudinal difference information and the transverse difference information are both 0, it is indicated that at least the upper surface and the lower surface of the corrugated board are in a flat state at the moment, the induction roller can move along the circumferential direction of the cut corrugated board to detect, the induction roller is still in a process of continuously vibrating up and down in a small amplitude in the moving process, and the length of the induction roller is consistent with the thickness of the corrugated core paper, so that the induction roller can detect the peripheral convex part.

Step 501: and judging whether the upper damping information and the lower damping information exist.

The purpose of the judgment is to determine whether or not a protruding portion exists, thereby judging whether or not there is a case of an adhesion error.

Step 5011: if at least one exists, outputting the paperboard dislocation information.

The paperboard dislocation information is information that the surface paper, the lining paper and the corrugated medium paper are not aligned and dislocated when the paperboards are bonded. If there is at least one damping indicating that the liner or liner paper has extended beyond the corrugated medium, it may happen that the liner and liner paper are misaligned during bonding, and the output is output

Step 5012: if the information does not exist, the leveling information is output.

If the paper sheets do not exist, the fact that no paper sheet protrudes at the moment is indicated, and the situation that the longitudinal difference information and the transverse difference information are both 0 is combined, so that the flatness information can be output at the moment.

Referring to fig. 6: if at least one of the upper damping information and the lower damping information exists, the method for outputting the paperboard dislocation information comprises the following steps:

step 600: and judging whether the upper damping information exists or not.

The purpose of the judgment is to determine the position where the damping information occurs.

Step 6001: and if so, acquiring the induction range information of the upper sliding roller corresponding to the upper damping information.

The information of the sensing range of the upper sliding roller is the information of the range of the position where the upper damping information is sensed, and at this time, the information of the range can be the information of the range because if the surface paper or the lining paper stretches out, the position is not a point but a certain length, and the information of the range can be related to two side lines of the corrugated board and can also be related to one side line of the corrugated board. If present, at least the upper side must have a bulge, and the extent of the corresponding bulge on the border line of the corrugated cardboard can be determined.

Step 6002: and if not, acquiring the induction range information of the lower sliding roller corresponding to the lower damping information.

The induction range information of the lower sliding roller is the range of the position where the lower damping information is induced when the induction roller starts to move along the side line circumference of the corrugated board from the starting point. If not, indicating that damping is occurring below, the corresponding scare range may be obtained. In this embodiment, when the upper damping information exists, the information about whether the lower damping information exists may also be obtained, and the purpose of the determination is to give an example of the misalignment of the upper paper sheet and the misalignment of the lower paper sheet, and the misalignment of synchronization may occur in the actual process, but the two are not affected, so that the determination needs to be performed again.

Step 601: and performing matching analysis according to the extension sideline and the upper sliding roller sensing range information stored in the preset area database to determine the extension sideline corresponding to the upper sliding roller sensing range information, and defining the extension sideline as the upper extension sideline information.

The upper protruding sideline information is information of the position of the sideline of the corrugated board when the upper damping information is sensed. The mapping relation between the upper sliding roller sensing range information and the upper extending sideline information is stored in the area database, namely the information on which sideline is located can be known when the distance is within a certain range, and the information is measured and calculated by workers in the field and is input.

Step 602: and performing matching analysis according to the vacant corners and the upper extended sideline information stored in the preset vacant position database to determine the vacant corners corresponding to the upper extended sideline information, and defining the vacant corners as the upper vacant corner information.

The upper vacant corner information is the information that the rest part of the panel can not cover all corner areas on the corrugated board after the part of the panel extends out of the side line of the corrugated medium paper. The mapping relation between the vacant corner information and the extended sideline information is stored in the vacant position database and is obtained by observing the vacant corner information and the extended sideline information by workers in the field according to experience and experiments. After the induction roller induces the damping information and converts the damping information into the upward extending sideline information, the system automatically obtains the upper vacant corner information according to the corresponding sideline information, and therefore subsequent operation is facilitated.

Step 603: and acquiring the preset induction distance of the test point positioned at the upper vacant corner information, and defining the preset induction distance as upper induction distance information.

The upper induction distance information is distance information for measuring the distance of the corresponding position by the testing instrument positioned above the upper vacant corner information. The obtaining mode can be obtained by measuring the distance by any distance measuring instrument.

Step 604: and acquiring the induction distances of the test points at the rest corners, and defining the induction distances as the approved induction distance information.

The upper approval sensing distance information is information of the rest of the ranging, in this embodiment, sensing distances of the other three corner positions. The manner of acquisition is consistent with step 603.

Step 605: and judging whether the upper sensing distance information is consistent with the upper approved sensing distance information.

When the surface paper does not cover the corrugated medium paper, the corrugated medium paper is tooth-shaped, so that the distance between the corner positions and the surface paper distance are different, and the purpose of judging whether the surface paper exists on the upper vacant corner information is to judge.

Step 6051: and if the position information is consistent with the preset upper surplus facial tissue information, outputting the preset upper surplus facial tissue information.

The information of the redundant surface paper is that the surface paper and the corrugated medium paper are attached, but the surface paper also has the situation that the redundant part extends out of the corrugated medium paper. If the two pieces of damping information are consistent, the fact that the upper vacant corner information contains the surface paper is indicated, the fact that the four corners of the surface paper are attached to the corrugated medium paper at the moment is indicated, the damping information of the induction roller is an extra part, and therefore corresponding upper redundant surface paper information is output. The output mode can be any mode which can be recognized by the staff, for example, a character of 'having excess tissue on the top' is displayed on the display screen.

Step 6052: if the paperboard is inconsistent with the paperboard, paperboard dislocation information is output.

If the two parts are not consistent, the paper is pulled by the extending part to form a corner, and the two parts do not match, and the paper board dislocation information can be output.

Step 606: and performing matching analysis according to the extension sideline and the induction range information of the lower sliding roller stored in the preset area database to determine the extension sideline corresponding to the induction range information of the lower sliding roller, and defining the extension sideline as the lower extension sideline information.

The lower extended sideline information is similar to the upper extended sideline information, and the difference is that one is the upper side surface paper and the other is the lower side surface paper, so the details are not repeated.

Step 607: and performing matching analysis according to the vacancy corners and the downward-extending sideline information stored in the preset vacancy position database to determine the vacancy corners corresponding to the downward-extending sideline information, and defining the vacancy corners as the downward-extending sideline information.

The lower vacant corner information is similar to the upper vacant corner information, and the difference is that one is the upper side surface paper and the other is the lower side surface paper, so the details are not described herein.

Step 608: and acquiring the preset induction distance of the test point positioned at the vacant corner information, and defining the preset induction distance as lower induction distance information.

The lower sensing distance information is similar to the upper sensing distance information, and the difference is that one is the upper side surface paper and the other is the lower side surface paper, so the details are not described herein.

Step 609: and acquiring the induction distances of the test points at the rest corners, and defining the induction distances as the next approved induction distance information.

The lower approval sensing distance information is similar to the upper approval sensing distance information, and is distinguished in that one is the upper side surface paper and the other is the lower side surface paper, so that the detailed description is omitted.

Step 610: and judging whether the lower induction distance information is consistent with the lower approved induction distance information.

When the surface paper does not cover the corrugated medium paper, the corrugated medium paper is tooth-shaped, so that the distance between the corner positions and the surface paper distance are different, and the purpose of judging whether the surface paper exists on the lower vacant corner information is to judge.

Step 6101: and if the position information is consistent with the preset position information, outputting the preset lower redundant facial tissue information.

The lower redundant facial tissue information is similar to the upper redundant facial tissue information, and the difference is that one is the facial tissue on the upper side, and the other is the facial tissue on the lower side, so the description is omitted here. If the two pieces of damping information are consistent, the fact that the lower vacant corner information contains the surface paper is indicated, the fact that the four corners of the surface paper are attached to the corrugated medium paper at the moment is indicated, the damping information of the induction roller is an extra part, and therefore the corresponding lower redundant surface paper information is output.

Step 6102: if the paperboard is inconsistent with the paperboard, paperboard dislocation information is output.

Similar to step 6052, further description is omitted here.

Referring to fig. 7, a method for correcting a value of warp degree information is also included, the method including:

step 700: and performing matching analysis according to the board placing direction and the warping type information stored in the preset placing database to determine the board placing direction corresponding to the warping type information, defining the board placing direction as the board placing direction information, and sending the board placing direction information to the board placing device.

The board placing direction information is the direction information of the corrugated board after the corrugated board is erected, for example, the corrugated board is transversely placed and corresponds to the information that a side line perpendicular to the conveying direction is abutted to a workbench, the rest part of the corrugated board is erected on the workbench, the cross section of each height is the same, the warping is generated in the horizontal direction, and the warping is not easily influenced by gravity.

Step 701: and after the board placing device is operated according to the board placing direction information, acquiring the horizontal angle curve information when the sliding roller moves along the horizontal direction.

The horizontal angle curve information is information of a curve of the rotation angle change of the supporting rod on the sliding roller when the sliding roller moves up and down along the horizontal direction of the corrugated board. The acquisition is by any means of measuring angles, such as an optical theodolite.

Step 702: and judging whether the longitudinal difference information is 0 or not.

The purpose of the determination is to determine whether or not there is any type of warp and thus to determine which warp curve information to compare with.

Step 7021: if so, calculating a difference curve according to the horizontal angle curve information and the transverse angle curve information, defining the difference curve as horizontal gravity influence information, and correcting the transverse angle curve information when the next measured longitudinal difference information is 0 according to the horizontal gravity influence information.

The horizontal gravity influence information is information of a difference curve calculated by horizontal angle curve information and transverse angle curve information, namely, the difference of different curves at different positions is set as a vertical coordinate, and the position information is set as a horizontal coordinate. When the longitudinal difference information is 0, it indicates that the warp is transverse warp, the comparison mode is transverse data comparison, and then the transverse angle curve information is corrected by the transverse data comparison.

Step 7022: if not, calculating a difference curve according to the horizontal angle curve information and the longitudinal angle curve information, defining the difference curve as vertical gravity influence information, and correcting the transverse angle curve information when the next measured longitudinal difference information is not 0 according to the vertical gravity influence information.

The vertical gravity influence information is information of a difference curve calculated by horizontal angle curve information and longitudinal angle curve information, namely, the difference of different curves at different positions is used as a vertical coordinate, and position information is set as a horizontal coordinate. When the longitudinal difference information is 0, the longitudinal warping is indicated, the comparison mode is longitudinal data comparison, and then the longitudinal angle curve information is corrected through the longitudinal data comparison.
