In this embodiment, further, the S2 specifically includes the following steps:
s21: assuming that the initialization i is 0, the coordinates A (X) of any two points on the frame are obtaineda,Ya)、B(Xb,Yb) And the frame length L and the number of frames j, obtaining the slope
By the formula
Calculating to obtain the length L of the pipelineAB；
S22: taking i-i +1 as a cycle, and comparing the pipeline length L according to a comparison judgment strategyABThe size of the frame length L and the system memoryRecording the numerical value of i and the current value of Length corresponding to the ith interception to obtain the coordinate of the point A;
s23: i loops until i equals the number j of frames, at which point the abscissa of the two points A, B are compared, which is used to detect and determine if the current pipeline is headed, e.g. Xa<＝XbThen step S3 is executed, otherwise, it indicates that the pipeline is up and needs to be changed direction, and the process returns to step S21.
In this embodiment, the comparison determination strategy is further determined if LAB<When the Length of the frame is L, that is, when the Length of the frame is greater than the Length of the pipeline, the Length of the frame is calculated by a function Length, round ddown (AB, -2) +100+ f _ d; of course, when the number of frames is only one or the calculated frame length is smaller than the frame length, if i is 0, it means that the distance from the point a 'to the point B' is taken, and if i is 1, the last point B 'is taken as a new point a', and a new line segment a 'B' is continuously intercepted, which may be specifically shown in fig. 3; if i is 1 or Length>When L/3, for example, when Length is 200, L is 300, 200>100, the actual condition is the condition that the bending amplitude of the pipeline is large and the slope is greatly changed, the length of the actually intercepted picture frame needs to be adjusted and corrected according to the condition of the pipeline, and the recording modification judgment step is executed for the situation; if L isAB>When L is reached, the coordinates of the point A are obtained

I.e. the number of i cycles equals the number of frames generated last, the frame width is wider than the pipeline width, the frame length is longer than the pipeline length and longer than twice the length of the overlapped part, the length of the pipeline is pre-determined, and the initial of the profile is inputThe frame length is redistributed according to the remaining length of the pipeline.

In this embodiment, the process of obtaining the two-point coordinates of the grid line in S4 is to obtain the point locations on the four end points OPQR of the frame that satisfy the scale arg. Because the coordinates of the four end points of OPQR are known, the grid distance is determined according to the scale, if the scale is 500, the grid distance is 50, that is, the x values of the abscissa of all the points with the distance of 50 on the straight line connected by OP are extracted, the y values of the ordinate of all the points with the distance of 50 on the straight line are extracted, specifically, as shown in fig. 4, the point Sj and the point Li are obtained, the perpendicular lines perpendicular to the y axis and the x axis are respectively made to the two adjacent sides PQ and OR of the point Sj, the abscissa of the intersection point Lj and the point Si is obtained, then, the abscissa of the pqline segment and the ordinate of the point with the distance of 50 on the OR are obtained according to the abscissa of the intersection point Lj and the ordinate of the point Si, the 50 square grid line is obtained, and finally, the end point coordinates of each frame and the coordinates of each point on the grid line are obtained. The csv file is similar to an excel data table and comprises a frame number and a frame length, and the frame number and the frame length information corresponding to the frame number are correspondingly recorded.
In this embodiment, the generating of the outline in S6 is further performed by determining whether the pipeline data in the frame length file is reasonably allocated, and the generating of the outline in S6 is performed by writing a command execution file in a CAD.

In this embodiment, the frame length file is a csv format file. CSV file: Comma-Separated Values, i.e., Comma Separated Values or character-divided Values, the file of which stores table data in the form of plain text. The file is a character sequence and can be composed of any number of records, and the records are divided by some line-feed character. Each record is made up of fields, and separators between fields are other characters or strings. All records have identical field sequences, corresponding to a plain text version of a structured table. The CSV file may be opened with a text file, EXcel, or the like. When the txt file is pasted into the CAD, the csv format file comprises a data table containing frame information, so that how long the corresponding frame of the next section is can be displayed, an actual operator judges whether the frame length distributed by the corresponding pipeline is reasonable or not, and if the frame length distributed by the corresponding pipeline is not reasonable, the input value of L is modified and the output frame length is obtained by calculating through the method. The problem that the coordinates of the points obtained through calculation cannot be mistaken in CAD drawing, but the coordinates can be deviated in manual operation, and the wrong points can be judged and checked only after the coordinates are printed out, so that the complexity and trouble of work are caused is solved.
The working principle and the working process of the invention are as follows: when the method is used, firstly, program software is operated, preset drawing parameters are input into the software, then the length of the overlapped part of two adjacent drawing frames is calculated according to the corresponding drawing parameters, then coordinate data are extracted from a CAD list command, the coordinate data are pasted into a newly-built named txt document, and the software program is operated and a text is read. Due to the pipeline, a plurality of lines are formed according to the trend of the pipeline, and a plurality of break point coordinates are obtained according to the extraction of the plurality of lines. Calculating the frame length according to the break point coordinates A, B, C of the cable, specifically, assuming that the initialization i is 0, obtaining the slope of AB under the condition of known A, B coordinates
The frame length L and the length f _ d of the repeated portion of two adjacent frames. Wherein, the frame length L is an actual ideal frame length. Cycling i +1Comparing pipelines L by comparison decision strategyABAnd comparing the size of the frame length L with the frame length L to determine the strategy as follows: if L isAB<And when the frame Length is equal to L, calculating the Length of the frame Length L equal to Length through a function Length equal to roundddown (AB, -2) +100+ f _ d, wherein the obtained frame Length has zero and integer, and since the values of the frame Length all exist in the form of whole hundred, the values of the frame Length need to be rounded and accurate to hundred, and roundddown (AB, -2) +100+ f _ d is rounding the Length of AB downwards and rounding the whole hundred.
To obtain a smoother frame Length, if i is 1 or Length>And when the record is equal to L/3, executing a record modification judgment step: the record modification judging step is concretely; if L isAB>When L is reached, the coordinates of the point A are obtained
The system records the numerical value of i corresponding to the i-th interception and the current value of the Length. And the record modification judgment step is to record the i value corresponding to the ith interception and the current value of the Length, otherwise, the value of the (i-1) th Length is modified to ensure that the i value corresponding to the ith interception is equal to the value of the i corresponding to the ith interception. I.e. length is reallocated, thereby reducing the difference in frame length allocation. The number of dropped frames is j, where the maximum value of i is equal to the number of frames j. Comparing A, B the abscissa sizes of the two points, e.g. Xa<＝XbOtherwise, the coordinates of each point in the frame are calculated according to the frame length, and the process returns to step S21 to continue. After four end point coordinates OPQR of the picture frame are obtained through calculation, two point coordinates of a grid line are obtained through calculation according to the point coordinates of each point of the picture frame, specifically, point positions meeting a proportional scale arg on OP, PQ, QR and RO are firstly obtained, the X-axis point position is an integral multiple of arg/10, and the Y-axis point position is an integral multiple of arg/10. And then generating a picture frame length file and a command execution file according to the element attributes, wherein the element attributes comprise two-point coordinates of a picture frame length L, a picture frame width W, a preset scale arg and a grid line, and the process of generating the picture outline is to copy the text content of the command execution file to CAD if the picture frame length in the picture frame length file meets the picture outline generation condition and finish the operation.
The embodiments of the present invention have been described in detail, but the description is only for the preferred embodiments of the present invention and should not be construed as limiting the scope of the present invention. All equivalent changes and modifications made within the scope of the present invention should be covered by the present patent.
