DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an optimized cable routing path detection method according to the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a flowchart of an optimized cable routing path detection method according to an embodiment of the present invention.

The tray path modeling unit generates the tray path using the device data and the tray data that are the path and destination of the cable installation (Step 100). Here, the device data includes the device name of the device on which the cable is installed, the device identification number, the space coordinate of the device, and the like. The tray data also includes a tray identification number, a tray classification code, a tray width, a tray height, a tray start position coordinate, a tray end position coordinate, a tray bend point position coordinate, and the like. 2 is a reference diagram showing an example of tray data, which includes a tray identification number (tray_no), tray space coordinates (point_x, point_y, point_z), and the like.

The tray path modeling unit creates (models) a two-dimensional or three-dimensional shape of the tray on which the cable is installed in space. Since only the minimum tray data is recorded in the data, the relation of the data is grasped in order to model the tray shape in two or three dimensions, and the actual shape of the tray is automatically reconfigured. The tray displayed increases the visibility by applying different colors based on the input data. FIG. 3 is a reference view showing an example of a tray modeled on a space using tray data, FIG. 4 is a view showing an example of an entire tray path modeled on a three-dimensional space using device data and tray data, . As shown in FIGS. 3 and 4, the warpage, the connection portion, and the size of the tray are implemented in three dimensions based on data. The three-dimensional cable routing path model thus implemented is free and fast to rotate / zoom / move / so that the complex structure can be easily recognized.

After step 100, the cable path modeling unit calculates the cable optimum for the cable based on the cable data for modeling the cable laying path, based on the path function value according to the tray length and cable occupancy of each tray existing between the starting point tray and the end point tray. The trays corresponding to the installed paths of the trays are detected (operation 102). Here, the cable data includes at least one of a cable identification number, a cable classification code, a cable specification, an identification number of the starting point device at which the cable starts, a space coordinate of the starting point device, an identification number of the end point device at which the cable ends, And the like.

FIG. 5 is a flowchart of an operation for explaining operation 102 of FIG.

The location of the starting point device and the end point device corresponding to the cable are designated using the space coordinates of the starting point device and the space point of the end point device (Step 200). The position corresponding to the information of the spatial coordinates of the starting point device of the cable and the information of the spatial coordinates of the end point device is designated on the tray path generated in operation 100. [

After step 200, a tray existing within the shortest distance from the starting point device is set as the starting point tray, and a tray existing within the shortest distance from the end point device is set as the end point tray in operation 202. The starting point of the cable Set the type of tray closest to the equipment and allowed to be installed on the cable as the starting point tray on the cable installation path. At this time, the distance between the starting point device and the set start point tray is also calculated. Also, set the trays of the type closest to the end point equipment of the cable and allowing the cable installation to be the end point trays on the cable laying path. At this time, the distance between the end point device and the set end point tray is also calculated.

After operation 202, trays corresponding to the optimal cable routing path are sequentially detected from the starting point tray according to the path function value (operation 204).

The path function value is calculated using the following equation (1).

(N) is a path weight value, G (n) is a total tray length required from the starting point tray to the tray n, W (n) is a path weight value according to the cable occupancy, and H This value corresponds to the distance from the tray n to the destination tray.

Here, tray n corresponds to any tray existing between the starting point tray and the end point tray. G (n) is the sum of the tray lengths from the starting point tray to the tray n through each tray.

The path weight W (n) is determined by the volume occupancy according to other installed cables in the tray, the weight occupancy according to other cables, the size of the tray, the value as the avoidance interval of the tray, And the value of one or more of the values. The following equation (2) is an example of a formula for calculating the path weight.

The volume occupancy is a value indicating the volume of the cable filled in the tray. The larger the value, the more bulky cables are installed. The weight share indicates the weight of the cable in the tray. The larger the value, the more heavy cables are installed. The tray size refers to the volume of the tray on which the cable can be laid, and a larger value means that more trays can be laid. The avoidance interval value is a value assigned to a large value when the tray is to be avoided if possible. The classification code corresponding value is a value according to whether or not the voltage level of the tray and the cable installed thereon coincides with each other. The smaller the value is, the higher the value becomes as the voltage level is matched (for example, Quot; 1 "if the grades match, and" 20 " if the grades do not match).

The smaller the path function value described above, the more optimal the tray path. That is, the tray having the lowest value of the path function value among the trays of the next trays that can be traced in the current tray is detected as an optimal tray. As described above, the components of the path function value may be used to determine the distance from the starting point tray to the tray n, the distance from the tray n to the end point tray, and the path weight (volume occupancy, weight occupancy, tray size, Code corresponding value). Since each of these values indicates that the smaller the size, the more likely it is to correspond to the optimum tray path. Therefore, in order to find the optimum tray path, do.

H (n) corresponds to the distance from the tray n to the end point tray. When the tray path generated in step 100 corresponds to the two-dimensional tray path, the shortest distance from the tray n to the end point tray, that is, . When the tray path generated in step 100 corresponds to the three-dimensional tray path, H (n) does not mean the straight line distance from the tray n to the finish point tray, but refers to the straight line distance from the tray n to the finish point tray , The sum of the lengths of the other two sides of the right triangle corresponds to the value of H (n).

In the present invention, the A star algorithm (A *) corresponds to the search algorithm for finding the route from the initial node to the target node in order to find the optimal cable route using the path function value. When an A-star algorithm is used to sequentially detect trays corresponding to candidates of the optimal cable path, the tray names or identifiers that have not yet been investigated are listed in the open_set table list, Write the tray name or identifier in the close_set table list.

6 is a reference view illustrating a tray path for a plurality of trays (a to j) including a starting point tray and a destination point tray. In Fig. 6, the identifier a is assumed to be a starting point trail, and the identifier i is assumed to be a trailing point trail. Also, the number between each tray means the distance between each tray.

When starting trays corresponding to the candidate group of the optimal cable path sequentially starting from the starting point tray a, the cable path is searched starting from the starting point tray a, and therefore, as shown in FIG. 6, (close_set) is recorded in the table list.

7 is a reference view illustrating trays corresponding to paths that can be installed in the starting point tray a. As shown in Fig. 7, it can be seen that the trays that are likely to be installed in the starting point tray a are intuitively tray b, tray d, and tray h. Therefore, the starting point tray a of the tray b, the tray d, and the tray h is recorded in the open_set table list. The path function value (F_score) can be calculated in FIG. 7 by detecting the path function value by using Equation (1), assuming that the placement path for each of the tray b, the tray d, and the tray h is designated.

For example, in the case of designating the installation route from the tray a to the tray b (the number of times of the arrival of the tray B), the value of G (b), i.e., the distance from the tray a to the tray b (G_score: 4) ) Value, that is, the distance from the tray b to the tray i (H_score: 7.3). Therefore, assuming that W (b) corresponding to the path weight is "1", the path function value F (b) = 4 * 1 + 7.3 = 11.3 can be calculated. The value G (h), that is, the distance (G_score: 1) from the tray a to the tray h and the value of H (h) That is, the distance from the tray h to the tray i (H_score: 7) can be confirmed. Therefore, assuming that W (h) corresponding to the path weight is "1", the path function value F (h) = 1 * 1 + 7 = 8 can be calculated. The value of G (d), that is, the distance from the tray a to the tray d (G_score: 2.5) and the value of H (d) when the installation route from the tray a to the tray d is designated (came_from: a-> d) That is, the distance from the tray d to the tray i (H_score: 6) can be confirmed. Therefore, assuming that W (d) corresponding to the path weight is "1", the path function value F (d) = 2.5 * 1 + 6 = 8.5 can be calculated. Here, for convenience of calculation, the path weight is set to "1 ".

As described above, a potential tray in which a cable can be installed in the departure tray a is found, added to the open set table list, and the expected path function value calculated when going through the trays in the open set table list, respectively If the path having the smallest value among the calculated path function values is selected, the path function value is "8" when the tracer is installed on the tray h, and is the smallest in comparison with the other path function values (11.3 and 8.5) . Therefore, provisionally set the installation route from tray a to tray h, and record tray h in the close_set table list.

After operation 204, it is determined whether a destination tray exists among the detected trays (operation 206). For example, it is determined whether or not the destination point tray i exists in the close_set table list shown in FIG. 7 described above. 7, if there is no end point tray i in the close_set table list, the process returns to operation 204 and repeats the process of sequentially detecting the tray path as shown in FIG. 8 .

8 is a reference view illustrating trays corresponding to paths that can be installed in the tray h. As shown in FIG. 8, it can be seen that the trays that are likely to be installed in the tray h are the tray b and the tray c. Therefore, the close_set table list contains the tray a and tray h already designated as cable routes, and tray b and tray c are recorded in the open_set table list together with tray d.

It is possible to calculate the path function value using Equation (1), assuming that an installation path for each of the tray b and the tray c is designated in the manner described in Fig. For example, when designating the installation route from tray h to tray b (came_from: h-> b), the value of G (b), i.e., the total distance from tray a to tray b through tray h + 1 = 2) and H (b), that is, the distance from the tray b to the tray i (H_score: 7.3). Therefore, assuming that W (b) corresponding to the path weight is "1", the path function value F (b) = 2 * 1 + 7.3 = 9.3 can be calculated. The value of G (c), that is, the total distance from the tray a to the tray c via the tray h (G_score: 1 + 1 = 2) and the H (c) value, that is, the distance from the tray c to the tray i (H_score: 5.5). Therefore, assuming that W (c) corresponding to the path weight is "1", the path function value F (c) = 2 * 1 + 5.5 = 7.5 can be calculated.

In the came_from table list of FIG. 8, it can be confirmed that the data is updated to the data on the installation route from the tray h to the tray b instead of the installation route from the tray a to the tray b in FIG. This is because the path function value (9.3) from the starting point a to the tray b through the tray a and the tray h is greater than the path function value from the tray a to the tray b (11.3) It is updated with data of a path whose path function value is small (an installation path from the tray h to the tray b) instead of the data of the path from the tray a directly to the tray b.

In this way, possible trays for which a cable can be installed in the tray h are found, added to the open set table list, and each of the expected path function values is calculated when going through the trays in the open set table list. The path having the smallest value among the path function values is selected. It can be seen that the path function value is "7.5", which is the smallest value in comparison with the other path function value (9.3), when it is installed from the tray h to the tray c. Therefore, provisionally set the installation route from tray h to tray c, and record tray c to the close_set table list.

Then, it is determined whether the destination tray i exists in the close_set table list among the detected trays. If the destination tray i does not exist in the close_set table list, the process returns to operation 204, 9, the process of detecting the tray path is sequentially repeated.

9 is a reference view illustrating trays corresponding to paths that can be installed in the tray c. As shown in FIG. 9, it can be seen that the trays that are likely to be installed in the tray c are the tray b, the tray e, the tray f, and the tray d. Thus, the close_set table list has already recorded the tray a, tray h and tray c designated as cable routes, and tray e and tray f together with tray b and tray d are recorded in the open_set table list .

It is possible to calculate the path function value using Equation 1, assuming that the placement paths for the trays b, t, e, and d are designated in the manner described in Figs. 7 and 8. For example, when designating the installation path from the tray c to the tray b (came_from: c-> b), the total distance to the tray b via the G (b) G_score: 1 + 1 + 1 = 3) and the H (b) value, that is, the distance from the tray b to the tray i (H_score: 7.3). Therefore, assuming that W (b) corresponding to the path weight is "1", the path function value F (b) = 3 * 1 + 7.3 = 10.3 can be calculated. The total distance from the tray c to the tray e via the tray a, the tray h, and the tray c (G_score: 1 + 1 + 3 = 5) and H (e), that is, the distance from tray e to tray i (H_score: 7). Therefore, assuming that W (e) corresponding to the path weight is "1", the path function value F (e) = 5 * 1 + 7 = 12 can be calculated. The total distance from the tray c to the tray f via the tray a, tray h, and tray c (G_score: 1 + 1 + 3 = 5) and H (f), that is, the distance from tray f to tray i (H_score: 4.5). Therefore, assuming that W (f) corresponding to the path weight is "1", the path function value F (f) = 5 * 1 + 4.5 = 9.5 can be calculated. The total distance from the tray c to the tray d via the tray a, the tray h, and the tray c (G_score: 1 + 1 + 1 = 3) and H (d), that is, the distance from the tray d to the tray i (H_score: 6). Therefore, assuming that W (d) corresponding to the path weight is "1", the path function value F (d) = 3 * 1 + 6 = 9 can be calculated.

In the came_from table list of FIG. 9, it can be seen that data on the installation path from the tray c to the tray b and data on the installation path from the tray c to the tray d are not described. This means that the path function value (9.3) to the tray b through the tray a and the tray h from the path function values required to go from the starting point tray a to the tray b becomes the path value to the tray b via the tray a, the tray h, Since the value is less than the function value (10.3), data going to tray b via tray c is excluded from the came_from table list. Among the path function values required to go from the starting point tray a to the tray d, the path function value (8.5) directly going to the tray d is the path function value (9) to the tray d via the tray a, the tray h, , The data going to tray d via tray c is excluded from the came_from table list.

In this manner, if possible trays capable of laying cables in tray c are found, added to the open set table list, and estimated path function values when going through the trays in the open set table list, 9, the path of the other trays (tray b, tray e, and tray f) having a path function value of "8.5" and capable of being installed in the case of being laid from the tray a to the tray d, (8.5), which is the smallest value compared to the function values (9.3, 12, and 9.5). Therefore, provisionally set the route to tray d and record tray d to the close_set table list.

Then, it is determined whether the destination tray i exists in the close_set table list among the detected trays. If the destination tray i does not exist in the close_set table list, the process returns to operation 204, And the process of sequentially detecting the tray path is repeated.

10 is a reference view illustrating trays corresponding to paths that can be installed in the tray d. As shown in FIG. 10, it can be seen that the tray that is likely to be installed in the tray d is the tray g. Therefore, in the close_set table list, the tray a, the tray h, the tray c, and the tray d already designated as the cable paths are recorded, and the tray g is the open_set table together with the tray b, the tray e, It is recorded in the list.

It is possible to calculate the path function value by using the equation (1), assuming that an installation path for the tray g is designated in the manner described in Figs. 7 to 9. For example, if you specify the installation path from tray d to tray g (came_from: d-> g), the value of G (g) through tray a, tray h, tray c, tray d, The distance from the tray g to the tray i (H_score: 2), ie, the total distance (G_score: 1 + 1 + 1 + 1 = 4) and H Therefore, assuming that W (g) corresponding to the path weight is "1", the path function value F (g) = 4 * 1 + 2 = 6 can be calculated.

In this way, if a potential tray g to which a cable is to be installed in the tray d is sought and is added to the open set table list, and the expected path function values are calculated when going through the trays in the open set table list, (Tray b, tray e, and tray f) having a path function value of "6 " in the case of being laid from the tray d to the tray g as shown in the came_from table list of Fig. (6) that is smaller than the path function values (9.3, 12, and 9.5). Therefore, provisionally set the route to the tray g, and write the tray g to the close_set table list.

Then, it is determined whether the destination tray i exists in the close_set table list among the detected trays. If the destination tray i does not exist in the close_set table list, the process returns to operation 204, The process of sequentially detecting the tray path is repeated as described above.

11 is a reference view illustrating trays corresponding to paths that can be installed in the tray g. As shown in Fig. 11, it can be seen that the trays which are likely to be installed in the tray g are the tray f and the tray i. Thus, the list of close_set tables already contains the tray a, tray h, tray c, tray d and tray g designated as cable routes, and tray i is an open set with tray b, tray e and tray f open_set) is listed in the table list.

It is possible to calculate the path function value using Equation (1), assuming that an installation path for each of the tray f and the tray i is specified in the manner described in Figs. 7 to 10. For example, when designating the installation path from tray g to tray f (came_from: g-> f), the value of G (f) the distance from the tray f to the tray i (H_score: 4) can be confirmed by the total distance (G_score: 1 + 1 + 1 + 1 + 3 = 7) Therefore, assuming that W (f) corresponding to the path weight is "1", the path function value F (f) = 7 * 1 + 4 = 11 can be calculated. In addition, when designating the installation path from the tray g to the tray i (came_form: g-> i), the value of G (i) (G_score: 1 + 1 + 1 + 1 + 2 = 6) and H (i) value = 0. Therefore, assuming that W (i) corresponding to the path weight is "1", the path function value F (i) = 6 * 1 + 0 = 6 can be calculated.

In the came_from table list of FIG. 11, it can be confirmed that data on the installation route from the tray g to the tray f is not described. Since the path function value (9.5) to the tray f via the tray c is smaller than the path function value (11) to the tray f through the tray g among the path function values required to go from the starting point tray a to the tray f, The data going to tray f through tray g is excluded from the came_from table list.

In this manner, if possible trays where the cable can be installed in the tray g are searched for and added to the open set table list, and the expected path function values are calculated when going through the trays in the open set table list, (Trays b, trays e, and trays f), where the path function value is set to "6" when the tracer is installed in tray i, as can be seen from the list of the came_from table in FIG. (6), which is the smallest value compared to the values (9.3, 12, 9.5). Therefore, provisionally set the path to the tray i and write the tray i to the close_set table list.

Then, it is determined whether the destination tray i exists in the close_set table list among the detected trays. As shown in FIG. 11, if there is a destination point tray i in the close_set table list, operation 208 is performed.

In operation 208, when there is a destination tray among the sequentially detected trays, each tray corresponding to a cable installation path from the destination tray to the starting tray in the reverse order is detected. Since there is a destination point tray i in the close_set table shown at the bottom of FIG. 11, it is possible to detect the tray g corresponding to the reverse order based on the destination point tray i in the came_from table list. Also, the tray d corresponding to the reverse order can be detected based on the tray g in the came_from table list, and the tray a corresponding to the reverse order can be detected based on the tray d. In other words, if you follow the tray in the reverse order from the last tray i in the came_from table list, you can detect the starting point tray a.

After operation 102, the cable path modeling unit detects a path of each of the detected trays as a cable installation path on the tray path (operation 104). As shown in Fig. 11, it is detected that the trays a, tray d, tray g, and tray i detected in reverse order in the came_from table list are optimal cable laying paths for the start point tray a and the end point tray i for the cable. At this time, the detected cable installation path may be a two-dimensional installation path, or a three-dimensional installation path.

On the other hand, in the above-described cable laying path, the route weight is set to "1" for convenience of calculation. However, in actual implementation, the cable laying route is not limited to the volume occupancy, weight occupancy, tray size, tray avoidance interval value, It is possible to set path weights other than "1 " depending on the value, etc., so that it is possible to detect an installation path that can avoid overloaded or non-conforming trays.

After operation 104, the installed path display unit displays the detected cable installation path together with the tray path (operation 106). When the selection of the entire laying path is completed, only the corresponding trays are displayed in the two-dimensional or three-dimensional lay path model, and the total required length of the cable is calculated and displayed. The installation rate of each tray is calculated and displayed.

12 is a reference diagram illustrating an optimal cable laying path. Start point device and end point The optimum path is selected by selecting the closest start point tray and end point tray closest to the device and automatically selecting the optimal installation path on the starting point tray and the end point tray. Therefore, the automatically selected cable laying route has the function of freely and quickly reviewing the rotation / enlargement / reduction / movement / movement so that the complex route can be easily recognized in the two- or three-dimensional laying route model. In addition, it is required that the installation route satisfying the classification code (voltage rating, safety grade), the volume occupancy rate and the weight occupancy rate of the cable are small and the installation route does not occur, When you specify a stopover tray that you should go to, you can automatically select the optimal installation route.

FIG. 13 is a block diagram of an embodiment of an optimized cable routing path detecting apparatus according to the present invention. The database 300 includes a tray path modeling unit 310, a cable path modeling unit 320, 330 and a control unit 340.

The database 300 stores cable data for modeling the path of cable installation, device data serving as a destination, and tray data and cable routing model, respectively. Here, the device data includes the device name of the device on which the cable is installed, the device identification number, the space coordinate of the device, and the like. The tray data also includes a tray identification number, a tray classification code, a tray width, a tray height, a tray start position coordinate, a tray end position coordinate, a tray bend point position coordinate, and the like. In addition, the cable data includes at least one of a cable identification number, a cable classification code, a cable specification, an identification number of the starting point device at which the cable starts, a space coordinate of the starting point device, an identification number of the end point device at which the cable ends, And the like.

The database 300 stores modeling data generated by the tray path modeling unit 310 and the cable path modeling unit 320.

The tray path modeling unit 310 generates a tray path using the device data and the tray data stored in the database 300. The tray path modeling unit 310 generates (models) a two-dimensional or three-dimensional shape of the tray on which the cable is installed. Since only the minimum tray data is recorded in the data, the tray path modeling unit 310 grasps the relationship of data and automatically reconstructs the actual shape of the tray in order to model the tray shape two-dimensionally or three-dimensionally. The tray displayed increases the visibility by applying different colors based on the input data. As shown in FIGS. 3 and 4, the tray path modeling unit 310 implements the warpage, connection, and size of the tray in three dimensions based on data. The tray path modeling unit 310 includes a function of performing rotation / enlargement / reduction / movement / movement so that the complex structure of the 3D cable installation path model can be easily recognized.

Based on the cable data stored in the database 300, the cable path modeling unit 320 calculates a cable path model based on the cable data stored in the database 300 according to the path function value according to the tray length and the cable occupancy ratio of each of the trays existing between the starting point tray and the end point tray. Detects each of the trays corresponding to the path, and detects the path of each of the traces detected as an optimal laying path of the cable on the tray path. The cable path modeling unit 320 detects a two-dimensional installation path or a three-dimensional installation path as an optimal cable installation path to be detected.

FIG. 14 is a block diagram of an embodiment for explaining the cable path modeling unit shown in FIG. 13, which includes a positioning module 322, a tray setting module 324, a tray sequential detection module 326, 328).

The location designation module 322 uses the space coordinates of the starting point device included in the cable data and the space coordinates of the end point device to specify the location of the starting point device and the end point device corresponding to the cable on the tray path.

The tray setting module 324 sets the tray that is within the shortest distance from the starting point device as the starting point tray and sets the tray that is within the shortest distance to the end point device as the destination point tray. The tray setting module 324 sets a tray of the type closest to the starting device of the cable and allowing the cable to be installed as a starting point tray on the cable installation route. At this time, the tray setting module 324 also calculates the distance between the starting point device and the set start point tray. In addition, the tray setting module 324 sets a tray of the type closest to the end point device of the cable and allowing the cable to be installed, as a destination point tray on the cable installation path. At this time, the tray setting module 324 also calculates the distance between the end point device and the set end point tray.

The tray sequential detection module 326 sequentially detects trays corresponding to the cable lay path from the starting point tray in accordance with the path function value.

The tray sequential detection module 326 detects trays corresponding to the lowest value of the path function value among the trays of the next trays that can be traced for each tray of each section. The tray sequential detection module 326 calculates the path function value using Equation (1). The smaller the path function value described above, the more optimal the tray path. That is, the tray having the lowest value of the path function value among the trays of the next trays that can be traced in the current tray is detected as an optimal tray. As described above, the components of the path function value may be used to determine the distance from the starting point tray to the tray n, the distance from the tray n to the end point tray, and the path weight (volume occupancy, weight occupancy, tray size, Code corresponding value). Since each of these values indicates that the smaller the size, the more likely it is to correspond to the optimum tray path. Therefore, in order to find the optimum tray path, do.

The tray sequential detection module 326 uses the A star algorithm to find the optimal cable path using the path function values. When the tray sequential detection module 326 sequentially detects the trays corresponding to the candidate group of the optimal cable path by using the A star algorithm, the tray name or the identifier not yet investigated is set as an open set, And list the tray name or identification symbol already checked in the close_set table list.

6, when the tray sequence detection module 326 detects trays corresponding to the candidate group of the optimal cable path sequentially starting from the starting point tray a, the tray sequence detecting module 326 searches the cable path starting from the starting point tray a , The starting point tray a is recorded in the close_set table list.

7, the tray sequential detection module 326 specifies an installation route for each of the tray b, the tray d, and the tray h, which are likely to be installed in the starting point tray a, To calculate the path function value. That is, the tray sequential detection module 326 finds possible trays where the cables can be installed in the departure tray a, adds them to the open set table list, and outputs the expected path when going through the trays in the open set table list Function values, and selects the path having the smallest value among the calculated path function values. As shown in FIG. 7, the tray sequential detection module 326 detects that the path function value is "8" when it is installed from the tray a to the tray h and is the smallest relative to the other path function values 11.3 and 8.5 , Temporarily set the installation path from tray a to tray h, and write tray h to the list of close_set tables.

Thereafter, the tray sequential detection module 326 determines whether a destination point tray is present among the detected trays. For example, the tray sequential detection module 326 determines whether a destination tray i exists in the close_set table list shown in FIG. 7 described above. As shown in FIG. 7, if the destination tray i does not exist in the close_set table list, the tray sequence detecting module 326 sequentially detects the tray path as shown in FIG. 8 Repeat.

As shown in FIG. 8, the tray sequential detection module 326 designates a placement path for each of the tray b and the tray c, which are likely to be installed in the tray h, and calculates a path function value using Equation (1). The tray sequential detection module 326 updates the data on the installation path from the tray h to the tray b to the came_from table list of Fig. 8 instead of the installation path from the tray a to the tray b in Fig. This is because the path function value (9.3) from the starting point a to the tray b through the tray a and the tray h is greater than the path function value from the tray a to the tray b (11.3) It is updated with data of a path whose path function value is small (an installation path from the tray h to the tray b) instead of the data of the path from the tray a directly to the tray b.

As such, the tray sequential detection module 326 finds possible trays where the cable can be laid out on the tray h, finds the trays, adds them to the open set table list, Function values, and selects the path having the smallest value among the calculated path function values. The tray sequential detection module 326 confirms that the path function value is "7.5 " when it is installed in the tray c from the tray h and is the smallest in comparison with the other path function values (9.3) , And records the tray c in the close_set table list.

Thereafter, the tray sequential detection module 326 determines whether the destination tray i exists in the close_set table list among the detected trays, and if the destination tray i does not exist in the close_set table list, The process of sequentially detecting the tray path is repeated as shown in FIG.

9, the tray sequential detection module 326 designates a placement path for each of the tray b, the tray e, the tray f, and the tray d, which are likely to be installed in the tray c, The function value is calculated. The tracer sequential detection module 326 determines that the path function value (9.3) to the tray b via the trays a and t among the path function values required to go from the starting point tray a to the tray b becomes the traverse a, (10.3) going to tray b, the data going to tray b via tray c is excluded from the list of came_from tables. The tracer sequential detection module 326 calculates a path function value (8.5) directly to the tray d from the path function values required to go from the starting point tray a to the tray d via the tray a, the tray h, (9), the data going to tray d via tray c is excluded from the came_from table list.

As such, the tray sequential detection module 326 finds possible trays on which the cable can be laid in the tray c, finds the trays to be added to the open set table list, Function values, and selects the path having the smallest value among the calculated path function values. The tray sequential detection module 326 detects the path function values of the other trays (tray b, tray e, and tray f) having a path function value of "8.5" 9.3, 12, and 9.5), and provisionally sets the tracing path to the tray d and records the tray d in the list of the close_set table.

Thereafter, the tray sequential detection module 326 determines whether the destination tray i exists in the close_set table list among the detected trays, and if the destination tray i does not exist in the close_set table list, The process of sequentially detecting the tray path is repeated as shown in FIG.

As shown in FIG. 10, the tray sequential detection module 326 designates an installation route for the tray g that is likely to be installed in the tray d, and calculates a path function value using Equation (1). As such, the tray sequential detection module 326 finds possible trays g on which the cables may be laid out in tray d, adds them to the open set table list, and is expected to go through the trays in the open set table list And calculates path function values. 10, the tray sequential detection module 326 detects the tray trajectory of the other trays (trays b, b, c, d, e, (6) that is the smallest value compared to the path function values (9.3, 12, 9.5) of the trays e and f), provisionally sets the installation route to the tray g, (close_set) Record in the table list.

Thereafter, the tray sequential detection module 326 determines whether the destination tray i exists in the close_set table list among the detected trays, and if the destination tray i does not exist in the close_set table list, The process of sequentially detecting the tray path is repeated as shown in FIG.

As shown in FIG. 11, the tray sequential detection module 326 designates a placement path for each of the trays f and trays i that are likely to be installed in the tray g, and calculates a path function value using Equation (1). The tray sequential detection module 326 calculates a path function value (9.5) from the starting point tray a to the tray f through the tray c to the tray f through the tray g, (11), the data going to the tray f via the tray g is excluded from the came_from table list.

Thus, the tray sequential detection module 326 finds possible trays on which the cable can be laid out on the tray g, adds them to the open set table list, and determines the expected path when going through the trays in the open set table list Respectively. As can be seen from the list of the came_from table in FIG. 11, the tray sequential detection module 326 detects the trays b (trays b, (6) that is the smallest value compared to the path function values (9.3, 12, 9.5) of the trays e and f), provisionally sets the installation route with the tray i, close_set) Write to table list.

Thereafter, the tray sequential detection module 326 determines whether the destination tray i exists in the close_set table list among the detected trays. 11, when it is determined that the destination tray i exists in the close_set table list, a signal indicating that the destination tray i exists in the close_set table list is transmitted to the optimal tray detection module 328 Output.

The optimal lay path detection module 328 detects each of the trays corresponding to the cable lay path from the end point tray to the starting point tray in reverse order. For example, in the close_set table shown at the bottom of FIG. 11, the optimal placement path detection module 328 determines that the end_trace_t table exists in the close_frame table list, The tray g is detected. Thereafter, the optimal laying path detection module 328 detects the tray d corresponding to the reverse order based on the tray g in the came_from table list, and detects the tray a corresponding to the reverse order based on the tray d. That is, the optimal placement path detection module 328 can detect the starting point tray a when it follows the tray in reverse order with respect to the destination point tray i in the came_from table list.

The optimal path detection module 328 detects the path of each tray detected in reverse order as the optimal path of cable deployment on the tray path. As shown in Fig. 11, the optimum laying path detection module 328 detects the arrival times of the start point tray a and the end point tray i in relation to the cable for the tray a, tray d, tray g, and tray i detected in reverse order in the came_from table list It is detected that the optimum cable installation route of the company. At this time, the optimal laying path detection module 328 detects a two-dimensional lay path or a three-dimensional lay path as a cable lay path.
