Description

  The present invention relates to a pipeline diagram creation device, a pipeline diagram creation program, and a pipeline diagram creation system that automatically generate a pipeline joint diagram based on pipeline construction management information acquired at a pipe laying construction site.

  Ancillary to the construction of pipes such as water supply pipe networks, the contractor writes information specifying the materials used for the pipes and construction details in the daily construction report at the end of the day's work, and the position of the pipe burial after the work is completed. It is necessary to submit to the construction manager a completed map representing the location and an offset map representing the exact burial position of the pipeline rather than the completed map.

  However, since the construction of such a document is very complicated for the contractor, there is a problem that it is difficult to guarantee the accurate information entry. For example, it is often the case that the various types of pipe materials used for construction and the embedment positions of each pipe are recorded in a notebook, and the above documents are created together with reference to the notes later. There were many transcription mistakes, and there were many cases where the position was measured after the pipes were buried, so that there was a problem of lack of accuracy.

  On the other hand, the water supply company, which is the source of pipe laying work, manually operates the laying information such as the laying route of the pipeline in the GIS (Geographic Information System) based on the completed drawing delivered from the contractor. There is also a problem that such an input operation is very complicated and there is a time delay until the information is reflected on the GIS after construction, and management is not possible in real time.

  Therefore, in Patent Document 1, daily report data created by a plumbing contractor every day is prepared for the purpose of reducing the trouble of creating daily reports and completed drawings by plumbing contractors such as waterworks contractors. There has been proposed a piping construction management system having means for inputting to a CAD system and means for creating a construction completion drawing from a plurality of daily report data input to the CAD system.

  Also, in Patent Document 2, a portable terminal that collects piping construction management information at a construction site of pipe laying construction and transmits it to the outside, and receives construction management information transmitted from the portable terminal and manages the construction status. A piping construction management system including a construction information management server has been proposed.

  The piping construction management system displays a code information reading unit that reads code information capable of acquiring pipe information including a pipe joint type and an input screen for specifying a pipe joining form on a portable terminal. The inspection information necessary for the evaluation of the joint part is generated from the pipe information obtained from the code information read by the code information reading part and the joint form specifying part and displayed on the notification screen An inspection item notification unit, and an inspection information input unit for inputting inspection information corresponding to the inspection item notified by the inspection item notification unit as a part of the construction management information, either a portable terminal or a construction information management server And an evaluation unit that evaluates whether or not the joint has been properly joined based on the inspection information input to the inspection information input unit.

  According to the above-described piping construction management system, the burden on the operator is reduced, but it is necessary to manually input the CAD system, and if incorrect data is input at that time, subsequent correction is difficult. For this reason, there was a problem that it could not be managed appropriately.

  According to the above-described piping construction management system, construction management including pipe information input via the code information reading section, position information of the joint portion of the pipe acquired using the GPS reception function provided in the mobile terminal, and the like. Since the information is immediately sent to the construction information management server, data input errors do not occur, the labor required for input work is reduced, and not only the contractor but also the contractor to the water supply entity can receive the data promptly. Can be provided.

  However, even in such a pipe construction management system, when creating a pipeline map, that is, a pipe joint diagram based on the inputted construction management information, the mapping program installed in the computer is started, It is necessary to draw a pipeline by a manual operation using an input device, and the burden of a complicated input operation has not been reduced.

  A joint point symbol is automatically drawn at a position corresponding to the joint point included in the construction management information on the pipe diagram layer managed on the computer, and the drawn joint point symbols are linear pipe symbols. It is possible to automatically connect, but since the joint point symbols could not be automatically drawn with a plurality of pipe symbols corresponding to the pipe shape, the pipe line was drawn manually in such a case. It was because I had to do it.

  In addition, for example, when three or more junction point symbols exist at a relatively short distance, it is not possible to automatically determine which junction point should be connected, and an operator's judgment is required. is there.

  In view of the above-described problems, an object of the present invention is a pipe diagram that can automatically generate a pipe joint diagram in a manner in which a pipe shape can be identified based on pipe construction management information acquired at a pipe laying construction site. It is in providing a creation device, a pipeline diagram creation program, and a pipeline diagram creation system.

A distance discriminating section is provided that permits connection between the joint symbols at the pipe line symbol when they are within a predetermined permissible length range.

  When connecting a starting point junction symbol with a pipeline symbol already connected and an ending point symbol with no pipeline symbol yet connected with a new pipeline symbol, a starting point junction symbol and an end point junction symbol Is longer than the effective length of the installed pipe, the position of the end point joining point symbol may not be appropriate. Therefore, the distance discriminating unit discriminates that the distance between the starting point joining point symbol and the end point joining point symbol is within a predetermined allowable length range corresponding to the pipe information, and the position of the end point joining point symbol is appropriate. In such a case, the drawing is performed so that the two connection point symbols are connected by the corresponding pipeline symbols.

  For example, when it is determined from the pipe information that the pipe to be joined is a straight pipe, the distance between the starting point joining point symbol and the end point joining point symbol is a predetermined value that allows for a predetermined margin in the corresponding straight pipe length. Is within the allowable length range, it is determined that the position of the end point joining point symbol is appropriate. It is determined that the position of the end point joining point symbol is inappropriate whether it is longer or shorter than the allowable length range. Even when the pipe to be joined is other than a straight pipe, the allowable length can be set based on the length between the pipe end portions.

Is done. For example, when it is determined from the pipe information that the pipe to be joined is a straight pipe, the end point joining point symbol is largely deviated from the extension line of the pipe line symbol connected to the starting point joining point symbol. When the deviation angle discriminating unit determines that the angle falls within a predetermined allowable angle range and the position of the end point joining point symbol is appropriate, the two connecting point symbols are connected with the corresponding pipeline symbol. Is drawn as follows.

A construction management information storage unit 1A for storing construction management information acquired every time, a pipe joint diagram creation unit 1D for drawing a pipe joint diagram on a pipe diagram layer, and a pipe drawn on the pipe diagram layer What is necessary is just to provide the pipe line information storage part 1E which stores a road junction diagram.

In the following, the pipeline connection diagram creating unit 1D will be mainly described in detail.
FIG. 2 shows main functional blocks of the pipe diagram creation device 1. The pipe diagram creation device 1 includes a construction management information storage unit 1A, a joint drawing processing unit D11, a pipe drawing processing unit D12, a pipe drawn by the joint drawing processing unit D11 and the pipe drawing processing unit D12. A pipe joint diagram display processing unit D13 that displays a road joint diagram superimposed on a map layer, and a pipe information storage unit D14 that stores a pipe joint diagram drawn on the pipe diagram layer. .

  The construction management information storage unit 1A includes position information indicating the position of the joint portion of the two pipes and pipe information of the pipe to be joined joined at the joint portion, and the construction management acquired for each joint portion of the pipe Information is stored.

  The joining point drawing processing unit D11 is configured to draw joining point symbols in the order of construction of each pipe at a position on the pipeline diagram layer corresponding to the position information read from the construction management information storage unit 1A.

  The pipe drawing processing unit D12 is a linear pipe symbol corresponding to the pipe information read from the construction management information storage unit 1A between the joint point symbols drawn on the pipe diagram layer by the joint drawing processing unit D11. It is comprised so that it may connect in the construction order of each pipe. The pipe drawing processing unit D12 includes a straight pipe drawing processing unit for connecting the joint point symbols with a straight pipe, a curved pipe drawing processing unit for connecting the joint point symbols with a curved pipe, and a T-shaped pipe between the joint point symbols. Each drawing processing unit of the T-shaped tube drawing processing unit to be connected, a distance determination unit that determines whether or not the connection point symbol at the connection destination is present at an appropriate position, and a connection point symbol at the connection destination Is provided with a deviation angle discriminating unit for discriminating whether or not the lens exists at an appropriate position based on the pipe laying direction.

  Position information indicating the position of the joint of the two pipes in the construction management information storage unit 1A, for example, latitude and longitude, altitude information as necessary, and pipe information of the pipe to be joined joined at the joint (straight pipe or Construction management information including information on pipe shapes such as curved pipes).

  In accordance with the position information read from the construction management information storage unit 1A, the joint point drawing processing unit D11 draws each joint point symbol on the corresponding pipeline diagram layer in the order of construction and reads the pipe information read from the construction management information storage unit 1A. Accordingly, drawing is performed by the pipe drawing processing unit D12 so that the connection point symbols are connected by a linear pipe symbol.

  The pipe joint diagram drawn on the pipe diagram layer is displayed superimposed on the map layer by the pipe joint diagram display processing unit D13, and the progress of the pipe construction can be visually confirmed. The pipe connection diagram drawn in such a pipe diagram layer is stored in the pipe information storage unit 1E. In addition, when the elevation information is included in the position information, a three-dimensional pipe connection diagram can be created.

  FIG. 3 shows an example of a pipe connection diagram. Circle marks are the junction symbol representing the junction points N1 to N5, and diagrams connecting the junction point symbols N1 to N5 are the pipeline symbols T1 to T4. Reference numeral T0 is an existing pipe, and an insertion port of the new pipe T1 is inserted and joined to a pipe end (receiving port) of the existing pipe. The structure of the joint is not only a push-on type joint structure, but also a type in which the flange is bolted, etc., but in this example, all are represented by the same joint point symbol. It is also possible to vary the joint symbol depending on the joint structure.

  The pipe symbols T1 and T3 are straight pipes, the pipe symbol T2 is a curved pipe having a bending angle of 90 °, and the pipe symbol T4 is a T-shaped pipe bifurcated. Straight pipes and deformed pipes such as curved pipes and T-shaped pipes are indicated by different pipe symbols. There are other curved pipes with 45 °, 22.5 °, 11.25 °, and 5.625 °.

  In the following, the connection point symbol with the pipeline symbol already connected is referred to as the start point connection point symbol, the connection point symbol with no pipe line symbol yet connected is referred to as the end point connection point symbol, and the start point connection point symbol is changed to the end point connection point symbol. A drawing process for connecting a new pipeline symbol will be described.

  When the joining point drawing processing unit D11 draws the end point joining point symbol, the pipe drawing processing unit D12 is activated, and when it is determined from the pipe information corresponding to the end point joining point symbol that the straight pipe is connected. The tube drawing processing unit is activated, and the straight tube drawing processing unit activates the distance determining unit and the deviation angle determining unit.

  As shown in FIG. 4, the distance determination unit uses a new pipe symbol T1 as a new pipe symbol T1 for a starting point junction point symbol N1 to which the pipe line symbol T0 has already been connected and an end point junction point symbol N2 to which the pipe line symbol has not yet been connected. When connecting (see FIG. 4A), it is determined whether or not the distance between the starting point joining point symbol N1 and the ending point joining point symbol N2 is within a predetermined allowable length range corresponding to the pipe information. When it is within the predetermined allowable length range, the straight pipe drawing processing unit is allowed to connect with the pipe symbol between the two joint symbols (see FIG. 4B).

  When the distance between the starting point joining point symbol N1 and the end point joining point symbol N2 deviates from a predetermined allowable length range corresponding to the pipe information, the end point joining point symbol N2 is a joining point by another construction. Alternatively, it is determined that the data is abnormal, and the drawing of the pipeline symbol is prohibited (see FIG. 4C).

  In the case of a straight pipe, the predetermined allowable length is set to a value in consideration of a predetermined margin for an effective length determined by the nominal diameter of the pipe. For example, in the case of a ductile cast iron pipe, a straight pipe having a nominal diameter of 100 has an effective length of 4 m at the maximum. Therefore, the upper limit of a predetermined allowable length range is set to 4 + 0.5 m, and the minimum is required when the straight pipe is used as a cut pipe. Since the effective length is 1 m, the lower limit of the predetermined allowable length range is set to 0.5 m.

  As shown in FIG. 5, the deviation angle discriminating unit sets a new pipe symbol to the starting point junction point symbol N1 to which the pipe line symbol T0 has already been connected and the end point junction point symbol N2 to which the pipe line symbol has not yet been connected. When connecting at T1 (see FIGS. 3 and 5A), if it is determined from the pipe information that the pipe to be joined is a straight pipe, a line segment connecting the starting point joining point symbol N1 and the ending point joining point symbol N2 Then, it is determined whether or not the angle with the extension line of the pipe line symbol T0 connected to the starting point joining point symbol N1 is within a predetermined allowable angle θ corresponding to the pipe information. When the angle is within the range of the predetermined allowable angle θ, the straight pipe drawing processing unit is allowed to connect the joints N1 and N2 with the pipe line symbol T1 (see FIG. 5B).

  In the present embodiment, the range of the predetermined allowable angle θ is set to ± 2 ° with respect to the extension line of the pipe symbol T0 connected to the starting point junction symbol N1, but it should be set according to the joint type. Is also possible. In the figure, for convenience of explanation, θ is shown at an angle larger than ± 2 °.

  When deviating from the predetermined allowable angle range θ, it is determined that the end point joining point symbol N2 is a joining point by another construction or is abnormal data, and drawing of the pipe symbol is prohibited (FIG. 5). (See (c)).

  As shown in FIG. 6, the curved pipe drawing processing unit converts the start point junction point symbol N2 to which the pipe line symbol T1 has already been connected and the end point junction point symbol N3 to which the pipe line symbol has not yet been connected to the new pipe symbol. When connecting at T2 (see FIGS. 3 and 6A), if it is determined from the pipe information that the pipe to be joined is a curved pipe having a predetermined bending angle, for example, 90 °, it is connected to the starting point joining point symbol N2. Assuming a line bent from the position of the curved line on the extended line of the pipeline symbol (see FIG. 6B), the line is connected by a linear pipeline symbol T2 reaching the end point junction symbol N3. (See FIG. 6 (c)).

  When connecting a starting point joint symbol, to which a pipe line symbol has already been connected, and an end point connecting point symbol, to which a pipe line symbol has not yet been connected, with a curved pipe having a predetermined curvature angle, the curved pipe drawing processing unit performs the starting point joint point. The line is connected by a linear pipe symbol that is bent from a position having the bending angle on the extension line of the pipe symbol connected to the symbol and reaches the end point joining point symbol.

  Whether or not the end point joining point symbol is within the range of the allowable angle θ is determined by using a predetermined curved angle and an allowable angle θ corresponding to the curved pipe information, and the pipeline symbol T2 with respect to the extension line of the pipeline symbol T1. Can be performed depending on whether the angle is within the range of the bend angle and the allowable angle θ.

  As shown in FIG. 7, the T-shaped pipe drawing processing unit newly sets the starting point junction point symbol N4 to which the pipe line symbol T3 has already been connected and the end point junction point symbol N5 or N6 to which the pipe line symbol has not yet been connected. When connecting with the pipe line symbol T4 (see FIGS. 3 and 7A), if it is determined from the pipe information that the pipe to be joined is a T-shaped pipe having a branch portion, the starting point joining point symbol N4 and the end point joining point Based on the angle between the line segment connecting the point symbol N5 or N6 and the extension line of the pipe line symbol T3 connected to the starting point connection point symbol N4, it is determined which pipe end portion is the connection position. Both junction point symbols are connected by the pipe line symbol T4. Actually, since the tube information for either one of the connection points of the end point symbol N5 or N6 is input first, it is necessary to identify which tube end it is.

  In this case, the above-described deviation angle determination unit is activated by the T-shaped tube drawing processing unit. In the end point joining point symbol N5, the angle with the extension line of the pipe line symbol T3 connected to the starting point joining point symbol N4 is within the range of a predetermined allowable angle θ corresponding to the pipe information, and in the end point joining point symbol N6, the starting point The angle with the extension line of the pipe line symbol T3 connected to the junction point symbol N4 deviates from the range of the predetermined allowable angle θ corresponding to the pipe information (see FIG. 7B).

  That is, in the case of a T-shaped tube, it can be determined which end portion the end point joining point symbol is based on whether or not the end point joining point symbol is within the range of the predetermined allowable angle θ. When the end point joining point symbol is within the range of the predetermined allowable angle θ, it is determined that the end point joining point symbol is N5, and when deviating, the end point joining point symbol is N6.

  If the end point joining point symbol is N5, a straight pipe line symbol is drawn, and a branching portion is drawn later when pipe information for the end point joining point symbol N6 is obtained (see FIG. 7C). Specifically, the branch pipe is drawn at an angle of 90 ° from a half point of the distance between the junction point symbols N4 and N5. Since it is known from the tube information that the two end point joining point symbols N5 and N6 are one T-shaped tube, such processing is possible.

  If the end point joining point symbol is N6, a line bent from a position having a bending angle of 90 ° on the extension line of the pipe line symbol T3 connected to the starting point joining point symbol N4 is assumed, and the line is the end point joining point symbol N6. Are connected by a linear pipe symbol T40 that reaches (see FIG. 7D).

Hereinafter, processing procedures of the construction management information collection device 2 and the pipeline diagram creation device 1 constituting the pipeline diagram creation system 100 will be described.
As shown in FIG. 8, the construction management information collecting device 2 installs a portable information terminal in the vicinity of the pipe joining portion every time the joining work between the pipes is completed by the pipe laying work performed at the construction site (S1, S2). Then, the position information is acquired via the GPS receiver (S3), and then the tube information label L affixed to the receiving end is read via the camera function to acquire the tube information of the receiving tube. (S4).

  The acquired position information and pipe information and preset construction information (construction management information including construction number, construction date, construction place, construction contractor, etc. are transmitted to the pipeline diagram creation apparatus 1 via WiFi ( S5) If the construction scheduled for that day has not been completed (S6), the processing from step S1 to step S5 is repeated, and when the scheduled construction for that day is completed, the construction management information collecting process is terminated. If WiFi cannot be used due to the radio wave conditions at the location where the pipe information is acquired, store the construction management information in a portable memory or the like and directly input it to the pipe diagram creation device 1 after the construction is completed, or You may comprise so that it may transmit via WiFi from the area | region where an electromagnetic wave condition is good.

  As shown in FIG. 9, when the pipe diagram creation device 1 receives the construction management information (S11), it stores the received information in the construction management information storage unit 1A (S12), and performs the mapping process, that is, the pipe joint diagram described above. The automatic generation process of the pipe joint diagram by the creation unit 1D is started (S13).

  The process from step S11 to step S13 is repeated until drawing of all the junction points and pipes included in the received construction management information is completed (S14). Thereafter, the automatically generated pipeline connection diagram is stored in the pipeline information storage unit 1E (S15). In this embodiment, an example is described in which a pipe joint diagram is automatically generated in real time every time construction management information is received. The joining diagram may be configured to be automatically generated.

  FIG. 10 to FIG. 13 show mapping processing, that is, pipe joint diagram automatic generation processing by the above-described pipe joint diagram creation unit 1D.

  As shown in FIG. 10, in the mapping process, it is determined from the construction management information stored in the construction management information storage unit 1A whether a new joint point exists with respect to the joint point of the existing pipe. It waits until it appears (S21).

  When a new joint point appears, the joint point symbol corresponding to the joint point is drawn as the starting point joint symbol (S22), and the shape of the tube for drawing from the end point joint symbol drawn immediately before it to the starting point joint point symbol is drawn. A determination is made based on the tube information (S23).

  If the pipe shape is a straight pipe, the straight pipe drawing processing unit is activated (S24). If the pipe shape is a curved pipe, the curved pipe drawing processing unit is activated (S25). It is activated (S26). When the pipe connection diagrams are drawn (S27), the same processing is repeated with the current end point connection point symbol as the next start point connection point symbol and the new end point as the new end point connection point symbol (S28). ).

  FIG. 11 shows straight pipe drawing processing. When the distance determination unit is activated by the straight pipe drawing processing unit, the distance between the end point joining point symbol and the newly created starting point joining point symbol is obtained from the position information indicating the joining point of both (S31), It is determined whether or not the distance between the two joint point symbols is within a predetermined allowable length range determined in correspondence with the effective length of the straight pipe (S32).

  If it is determined that the distance between the starting point joining point symbol and the ending point joining point symbol is within a predetermined allowable length range (S32), then the deviation angle discriminating unit is activated, and the starting point joining point symbol and the end point joining point are activated. It is determined whether or not the angle between the line segment connecting the point symbols and the extension line of the pipe symbol connected to the starting point junction point symbol is within a predetermined allowable angle range corresponding to the pipe information (S33, S34). When it is determined that the angle is within the allowable angle range (S34), the straight pipe drawing processing unit draws a diagram between the two junction symbols with a diagram showing the straight pipe (S35). If it is determined in step S32 or step S34 that the allowable range is exceeded, the process ends without performing the drawing process.

  FIG. 12 shows a curved pipe drawing process. When the distance determining unit is activated by the curved pipe drawing processing unit, the distance between the end point joining point symbol and the newly created starting point joining point symbol is obtained from the position information indicating the joining point of both (S41). It is determined whether or not the distance between both junction point symbols is within a predetermined allowable length range determined in correspondence with the distance of the pipe end pipe of the curved pipe (S42).

  If it is within the allowable length range, the curve angle information (for example, 90 °) is taken from the tube information (S43), and the deviation angle discriminating unit is activated to obtain the starting point joining point symbol and the end point joining point symbol. It is determined whether or not the angle between the connecting line segment and the extension line of the pipe symbol connected to the starting point junction point symbol is within a predetermined allowable angle range corresponding to the pipe information (S44, S45). When it is determined that it is within the range, the curved pipe drawing process starts. The allowable angle range is an angle determined in consideration of a predetermined margin in the angle formed between the tube extending direction on one end side of the curved tube and the other tube end portion.

  In the curved pipe drawing process, based on the curve information from the tube information, out of the line segments extending at the angle of the curve angle from the extension line of the pipe symbol connected to the starting point joint symbol, The starting point of the arriving line segment is specified on the extension line of the pipeline symbol as a break point (S46), and a linear pipeline symbol that bends from that position and reaches the end point joining point symbol is created (S47). .

  FIG. 13 shows a T-shaped tube drawing process. For the T-shaped tube, the allowable length and the allowable deviation angle are determined in the same manner as the curved tube (S51 to S54). When the above conditions are satisfied, the process proceeds to the next step. Since the T-shaped tube has two receptacles, it is necessary to automatically determine which receptacle the end point junction point symbol is.

  First, it is determined whether the two receiving ports exist within a predetermined allowable range by determining the allowable length, and then, which of the two receiving ports is the end point junction point symbol by determining the allowable deviation angle. It is determined whether it is present. If it is within the allowable angle range, it is determined that the receiving port is on the straight pipe side, and if it deviates, it is determined that the receiving port is a pipe orthogonal to the straight pipe.

  If the T-tube drawing processing unit determines that the end point joining point symbol is on the extension of the line segment connecting the starting point joining point symbol and the end point joining point symbol based on the determination result of the allowable deviation angle (S55, Y ), The starting point joining point symbol and the end point joining point symbol (first end point joining point symbol) are drawn in a straight line (S57). Later, when the junction point information for the branch side receptacle is received, a branch line is drawn from the midpoint of the straight line to the second end point junction symbol that is the branch side receptacle (S59).

  If the T-tube drawing processing unit determines that the end point joining point symbol does not exist on the extension of the line segment connecting the starting point joining point symbol and the end point joining point symbol based on the determination result of the allowable deviation angle, Of the line segments that are determined to be receiving ports (S55, N) and extend at an angle of 90 ° from the extension line of the pipe symbol connected to the starting point connection point symbol, the line segment that reaches the end point connection point symbol The starting point is specified on the extension line of the pipe symbol as a break point, and a pipe symbol is drawn with an L-shaped line segment bent from that position and reaching the end point joining point symbol (S56). Later, when joint point information for the straight pipe side receiving port is received, a straight line is drawn from the L-shaped bending point to the second end point joining point symbol which is the straight pipe side receiving port (S57).

As described above, the construction management information is information that is sequentially collected at the joining point of the pipe every time the joining operation of the pipe is completed, but when information on a plurality of joining points is transmitted together, There is a risk of causing a situation in which the joining order cannot be specified. Therefore, it is preferable that the time information at the time of collecting the information regarding the joint point is included in each, and the construction order of each pipe is specified based on the time information.

When construction management information is information that is sequentially collected at the joint point of the pipe every time pipe joining work is completed and includes time information at the time of collection, it is randomly entered and entered into the construction management information storage unit Even so, since the construction order can be determined based on the time information, the joint point symbol and the pipe line symbol can be drawn in the construction order according to the time information. In addition, in order to draw in the construction order when the time information is not included, it is necessary to arrange the data in the construction order, or from the joint position data included in the construction management information on the pipe diagram creation device side between the joint positions Although it is necessary to estimate the construction order based on the distance and the like, according to the above-described configuration, it is freed from such a restriction.

A curved pipe drawing processing unit connected by road symbols is provided.

  Further, the pipe drawing processing unit uses the new pipe symbol to connect the starting point joint symbol, to which the pipe symbol has already been connected, and the end point joint symbol, to which the pipe symbol has not yet been connected, with a new pipe symbol.

In addition, if a pipeline map creation program according to the present invention is constructed in a geographic information system (GIS), the pipeline joint map on the geographic information system can be updated in real time.
