Description

  Embodiments described herein relate generally to a wire length correction work support device, a wire length correction work support method, and a program.

  The switchboard is composed of tens to hundreds of appliances per case. Each of these instruments functions by being connected by electric wires. Dozens of electric wires are connected to each of these appliances. In addition, there are products that connect to other panels via a connection device such as a terminal block in order to realize the required functions of the switchboard. For this reason, there are few tens of wires and thousands of wires in the cabinet of the switchboard. Especially in the switchboard, the number of electric wires is larger than the size of the duct, and bending the electric wires in the duct or accommodating the extra length also affects the number of electric wires that can be put into the duct. In order to accommodate this large amount of electric wires in the cabinet of the switchboard, it is necessary to measure each electric wire with an optimum length.

  On the other hand, since there are many appliances and ducts installed on the switchboard, it is necessary to consider not only the positional relationship of the appliances but also various factors such as the separation of ducts, routes, and weak and strong electric currents in this wire length measurement. There is. Particularly in actual manufacturing, the positions of electric wires and instruments are often adjusted and changed in accordance with site-specific rules. Therefore, at the manufacturing site, the length of the electric wire used for the switchboard is automatically measured, and the presence / absence of correction of each electric wire is confirmed for the length measurement result. This operation may be a heavy burden for the wire processing operator.

First, the length measurement unit 2 of the wire length correction work support device 1 inputs the length measurement DB from the storage unit 3 and reads it (step S1). The length measuring unit 2 refers to the drawing data and specifications / master data included in the length measurement DB, and automatically measures the length of the wire indicated by each wire data list included in the wire data list D11a of the switchboard to be operated (step S2). ). Any existing technique can be used for automatic length measurement. The length measuring unit 2 sets an automatic length measurement result for each wire data in the wire data list D11a. The wire length correction work support device 1 displays the wire data list D11a in which the automatic length measurement result is set on the display unit 6 (step S3). At this time, the correction necessity management unit 4 performs control so that the electric wire data of the electric wires that do not need to be corrected is hidden or displayed in a manner that indicates that the correction is unnecessary. Further, the correction rate management unit 5 performs control so that the electric wire data is displayed in a manner representing the correction weight.

  The worker manually inputs corrections to the electric wire data included in the displayed electric wire data list D11a with the input unit 7 as necessary to obtain an electric wire data list D11b (step S4). The correction target is, for example, a measurement result of the electric wire, a route through which the electric wire passes, or the like. The length measuring unit 2 of the wire length correction work support device 1 performs re-measurement of the wire using the manually corrected wire data list D11b (step S5). The length measuring unit 2 sets the result of re-measurement to each wire data in the wire data list D11b. The wire length correction work support device 1 displays the wire data list D11b in which the re-measurement result is set on the display unit 6 (step S6). At this time, the correction necessity management unit 4 performs control so that the electric wire data of the electric wires that do not need to be corrected is hidden or displayed in a manner that indicates that the correction is unnecessary. Further, the correction rate management unit 5 performs control so that the electric wire data is displayed in a manner representing the correction weight. The length measurement unit 2 of the wire length correction work support device 1 outputs the wire processing data D12 obtained by adding the remeasured wire length to the wire data list D11b to the next manufacturing process such as a wire processing machine (step S7). .

Next, processing of the correction necessity management unit 4 will be described.
FIG. 3 is a flowchart showing the correction-unnecessary electric wire detection process of the correction-unnecessary electric wire detection unit 41. The correction-unnecessary electric wire detection unit 41 performs the correction-unnecessary electric wire detection process shown in FIG. 2 before the electric wire length measurement process (step S2) in FIG. First, the correction unnecessary electric wire detection part 41 acquires the electric wire data list D11a and the correction unnecessary electric wire list D13 (step S11).

  FIG. 12 is a diagram illustrating an example of the electric wire data list D11a. The electric wire data shown in the figure includes an electric wire ID, length measurement information, electric wire specification information, connection format information, and appliance location information. The electric wire ID is identification information for identifying the electric wire. The length measurement information includes automatic length measurement value, corrected length measurement value, and length measurement date / time information. The length measurement information may further include worker information for specifying a person who has measured the length and a person who has corrected the length measurement. The automatic length measurement value is the wire length obtained as a result of the length measurement unit 2 performing automatic length measurement. The corrected length measurement value is the wire length after manually correcting the wire length as a result of automatic length measurement. The length measurement date and time indicates the date and time when automatic length measurement was performed. The electric wire specification information includes information on the size of the electric wire and the type of the electric wire. The wire specification information may further include items such as a wire color. The connection format information includes items such as a FROM format, a TO format, and an adjacent terminal flag. The FROM format indicates the format of the appliance from which the wire is connected. The TO format indicates the format of the appliance to which the wire is connected. The type of the instrument is represented by the model of the instrument, for example. The adjacent terminal flag indicates whether the connection source terminal and the connection destination terminal of the electric wire are adjacent to each other. The appliance location information includes a FROM location, a TO location, and the same stage flag. The FROM location indicates the position within the housing of the part from which the wire is connected. The TO location indicates the position in the casing of the part to which the electric wire is connected. The same stage flag indicates whether or not the connection source part and the connection destination part of the electric wire are located at the same stage in the housing.

  The electric wire data may further include route information, a front / rear connection flag, another housing connection flag, and a door / housing flag. The route information indicates a duct through which the electric wire passes. The front / rear connection flag indicates whether the electric wire connects the front instrument and the rear instrument in the housing. The other case connection flag indicates whether the electric wire is connected to the other case. The door / in-chassis flag indicates whether an appliance in the casing is connected to the back side of the door or connected to the inside of the casing.

  The component is, for example, a setting content in a certain item such as a value such as “D”, “E”, or “F” set in the size item.

For example, numerical data for automatic measurement value, corrected measurement value, etc., character string data for connection type information, route information, etc., adjacent terminal flag, same stage flag, front / rear connection flag, other chassis connection flag Can use logical value data indicating TRUE or FALSE.

  FIG. 13 is a diagram illustrating an example of the correction unnecessary electric wire list D13. The correction unnecessary electric wire list D13 is generated by a correction unnecessary electric wire list creation process of FIG. The correction unnecessary electric wire list D13 indicates a list of combinations of components of the correction unnecessary electric wires created using the past electric wire data. The items constituting the combination of the components of the correction-unnecessary electric wires are items obtained by excluding the items taking the specific set values for each switchboard from the electric wire data items, and are determined in advance. In the case of the correction-unnecessary wire list D13 shown in the figure, the items constituting the combination of the components of the correction-unnecessary wires are the size and type obtained from the wire specification information, the FROM format, the TO format and the adjacent terminal obtained from the connection format information It is the same stage flag obtained from the flag and the appliance location information. The correction-unnecessary electric wire list D13 shown in the figure does not register items unique to the measurement of the electric wires of a specific switchboard, such as the automatic measurement values and FROM locations included in the electric wire data list D11a shown in FIG.

  As illustrated in FIG. 3, the correction-unnecessary electric wire detection unit 41 performs the processing from step S12 to step S13 for each electric wire, that is, for each electric wire data included in the electric wire data list D11a. Of the electric wires registered in the electric wire data list D11a, the electric wires to be processed in the loop processing of Step S12 to Step S13 are described as the electric wires to be processed, and the electric wire data of the electric wires to be processed are described as the electric wires to be processed.

  The correction unnecessary electric wire detection unit 41 performs a condition matching determination process on the processing target electric wire data (step S12). In the condition match determination process, the correction-unnecessary wire detection unit 41 compares the component of each item of the processing target wire data with the combination of the components included in the correction-unnecessary wire list D13. If the correction-unnecessary-wire detecting unit 41 determines that there is a combination of all of the constituent elements registered in the correction-unnecessary-wire list D13 and the processing-target wire data (step S12: YES), the processing-target wire is selected. Recognizing that the wire does not require correction, a list addition process is performed (step S13).

  FIG. 14 is a diagram illustrating an example of the display unnecessary list D14. When the electric wire data list D11a shown in FIG. 12 and the correction unnecessary electric wire list D13 shown in FIG. 13 are used, among the electric wire data set in the electric wire data list D11a, the combination of the components registered in the correction unnecessary electric wire list D13 is Matching is the wire data of the wire ID = 2. The correction unnecessary electric wire detection unit 41 registers the electric wire ID in the display unnecessary list D14.

  The correction-unnecessary electric wire detection unit 41 performs the condition matching determination process (step S12) to the list addition process (step S13) for all the electric wire data registered in the electric wire data list D11a. By the above procedure, the wire IDs of all the correction-unnecessary wires among the wire data measured in the wire length measurement process (step S2) are stored in the display unnecessary list D14. Finally, the correction unnecessary electric wire detection unit 41 performs DB reflection processing for reflecting the display unnecessary list D14 in the length measurement DB stored in the storage unit 3 (step S14), and ends the processing.

  FIG. 4 is a flowchart showing the non-display process of the electric wire list display control unit 42. The non-display process shown in FIG. 4 functions in the result display process of step S3 or step S6 shown in FIG.

  First, the electric wire list display control unit 42 acquires the electric wire data list D11a, the electric wire data list D11b after manual correction, and the display unnecessary list D14 (step S21). The electric wire data list D11a and the manually corrected electric wire data list D11b are collectively referred to as an electric wire data list D11.

  The electric wire list display control unit 42 performs the processing from step S22 to step S24 for each electric wire, that is, for each electric wire data included in the electric wire data list D11. Among the electric wire data registered in the electric wire data list D11, the electric wire data to be processed in the loop processing of Step S22 to Step S24 is described as processing target electric wire data.

  The wire list display control unit 42 performs a wire ID match determination process on the processing target wire data (step S22). That is, the electric wire list display control unit 42 checks whether or not the electric wire ID set in the processing target electric wire data matches any of the electric wire IDs set in the display unnecessary list D14. When it is determined that they match (step S22: YES), the wire list display control unit 42 performs a non-display process on the processing target wire data (step S23), and when it is determined that they do not match (step S22: NO) Display processing is performed on the target electric wire data (step S24).

  FIG. 15 is a diagram illustrating a display example of the electric wire data that has been subjected to the non-display process of step S23 using the display unnecessary list D14 of FIG. The wire list display control unit 42 fills in the dark gray color because the wire data of the wire ID = 2 set in the display unnecessary list is the target of the non-display process among the wire data of the wire data list D11. It is displayed inconspicuously. A format that makes it difficult for the operator to recognize and be conscious of the wire data to be hidden in the wire data, such as not displaying the wire data to be hidden from the wire data list, displaying the background or characters in a specific color, etc. The expression method is not limited as long as it can be changed. The electric wire list display control unit 42 displays the list as usual for the electric wire data subjected to the display processing in step S24.

  As shown in FIG. 4, the electric wire list display control part 42 performs the process of the above step S22 to step S24 with respect to all the electric wire data of electric wire data. This eliminates the need for the operator to determine whether or not the correction of the automatic length measurement result is necessary for the electric wires that need not be corrected and are registered in the display unnecessary list D14.

  Next, the correction-unnecessary electric wire list creation process by the correction-unnecessary electric wire list creation unit 43 will be described. The correction unnecessary electric wire list creation processing is performed at an arbitrary timing after the manual correction (step S4) shown in FIG.

  FIG. 5 is a flowchart showing a correction-unnecessary electric wire list creation process of the correction-unnecessary electric wire list creation unit 43. First, the correction unnecessary electric wire list creation unit 43 acquires the electric wire data list D11b after manual correction (step S31).

  FIG. 16 is a diagram illustrating an example of the electric wire data list D11b. In the figure, a value is manually added to the item of the measured length value after correction of the electric wire that needs to be corrected with respect to the electric wire data list D11a shown in FIG.

  Next, as illustrated in FIG. 5, the correction-unnecessary electric wire list creation unit 43 performs the processing from step S32 to step S35 for each electric wire, that is, for each electric wire data registered in the electric wire data list D11b. Of the electric wire data registered in the electric wire data list D11b, the electric wire data to be processed in the loop processing of step S32 to step S35 is described as processing target electric wire data.

  First, the unneeded correction wire list creation unit 43 determines whether or not the processing target wire data has been manually corrected (step S32). Here, the correction unnecessary electric wire list creation unit 43 refers to the constituent elements of the length measurement information such as the corrected electric wire length and route of the processing target electric wire data, and determines whether or not a value has been input or updated. For example, the determination may be made with reference to a correction flag added to the electric wire data during manual correction, or a list of electric wire IDs of the corrected electric wire data may be generated and the list may be referred to. . Or you may compare the electric wire data list D11a before correction | amendment, and the electric wire data list D11b after correction | amendment. In the present embodiment, the correction-unnecessary wire list creation unit 43 confirms the item of the length measurement value after correction in the processing target wire data, and if the value is included, the wire is manually corrected. If the value is not, the manual correction is performed. Judge that the wire is not. In the case of the wire data list D11b shown in FIG. 16, the correction-unnecessary wire list creation unit 43 determines that the processing target wire data with the wire ID = 2, 4 is not manually corrected.

  When it is determined that there is no manual correction (step S32: YES), the correction-unnecessary wire list creation unit 43 performs the determination process of step S33. That is, the correction-unnecessary wire list creation unit 43 determines whether or not the combination of components set in the processing-target wire data exists in the correction-unnecessary wire list D13 registered in the storage unit 3 (step). S33).

  When the correction unnecessary electric wire list creation unit 43 determines that the combination of the components set in the processing target electric wire data does not exist in the correction unnecessary electric wire list D13 (step S33: YES), the list addition processing in step S34 is performed. . For example, it is assumed that the correction unnecessary electric wire list D13 is data shown in FIG. For the wire data of wire ID = 4 included in the wire data list D11b after manual correction shown in FIG. 16, there is no combination of components in the unneeded wire list D13. Therefore, the list addition process in step S34 is performed. That is, the correction-unnecessary wire list creation unit 43 adds the combination of components of the processing target wire data to the correction-unnecessary wire list D13 (step S34), and reflects the added correction-unnecessary wire list D13 in the storage unit 3. (Step S35). FIG. 17 is a diagram illustrating the correction-unnecessary wire list D13 after the result of the process using the wire data list D11b of FIG. 16 is reflected.

  As illustrated in FIG. 5, the correction-unnecessary wire list creation unit 43 determines that manual correction is present in the processing target wire data (step S32: NO), or a component set in the processing target wire data Are determined to be present in the correction-unnecessary wire list D13 (step S33: NO), the processing of step S34 and step S35 is not performed.

  The correction-unnecessary wire list creation unit 43 performs the processing from step S33 to step S35 on each of all the wires registered in the wire data list D11b, and ends the processing. As a result, a correction-unnecessary electric wire list D13 indicating a list of electric wire component combinations that have not been corrected in the past is recorded in the storage unit 3.

  Next, the processing of the correction rate management unit 5 will be described. The correction factor management unit 5 refers to the past database and calculates a quantitative value indicating how much the target electric wire may be corrected. The correction rate management unit 5 visualizes the possibility of correction by visually displaying the possibility together with a number to the wire processing operator. As a result, the operator needs to correct how much wire in the entire target measurement data and how much work is likely to be burdened. It is possible to grasp without confirming specific numerical values such as indicators.

  FIG. 6 is a flowchart showing the wire correction rate digitization processing of the correction rate calculation unit 51. The wire correction factor digitization process shown in the figure is performed in the wire length measurement process (step S2) shown in FIG. First, the correction factor calculation unit 51 acquires the wire data list D11a and the correction factor weight list D15 stored in the storage unit 3 (step S41).

  FIG. 18 is a diagram illustrating an example of the correction rate weight list D15. The correction factor weight list D15 indicates a combination list of components of correction-unnecessary electric wires created from the length measurement data up to the previous time. The correction factor weight list D15 is generated by the correction weight calculation process of FIG.

  Next, as illustrated in FIG. 6, the correction factor calculation unit 51 performs the processing from step S42 to step S44 for each electric wire, that is, for each electric wire data registered in the electric wire data list D11a. Of the electric wires registered in the electric wire data list D11a, the electric wires to be processed in the loop processing of step S42 to step S44 are described as the processing target electric wires, and the electric wire data of the processing target electric wires are described as the processing target electric wire data. Furthermore, the correction factor calculation unit 51 performs the processing from step S42 to step S43 for each item of one electric wire. Among the items registered in the processing target electric wire data, items that are processing targets in the loop processing of Step S42 to Step S43 are described as processing target items.

  The correction factor calculation unit 51 refers to the correction factor weight list D15 and reads the weight value corresponding to the component of the processing target item set in the processing target wire data (step S42). The correction factor calculation unit 51 calculates the weight of the correction factor of the processing target electric wire using the read weight (step S43). The calculation method starts with an initial value of 0 points for each identical wire and calculates by the addition method. Therefore, every time the loop processing is performed, the correction factor calculation unit 51 adds the weight read in step S43 to the current correction factor weight of the processing target electric wire.

  The correction factor calculating unit 51 can obtain the total value of the weights of all the components of the electric wire by performing the processing from step S42 to step S43 for all items of one electric wire to be processed. Let this total value be the wire correction factor of the wire. The correction factor calculation unit 51 performs a list addition process for reflecting the wire correction factor calculated for the processing target wire in the wire correction factor list (step S44). Specifically, the correction rate calculation unit 51 adds data in which the wire ID of the processing target wire is associated with the wire correction rate calculated for the processing target wire to the wire correction rate list D16.

  FIG. 18 is a diagram illustrating an example of the correction rate weight list D15. As shown in FIG. 18, weights with the component degrees of each item are set in the correction rate weight list. FIG. 19 is a diagram showing an example of the wire correction factor list D16 obtained using the wire data list D11a shown in FIG. 12 and the correction factor weight list D15 shown in FIG. According to the wire data list D11a shown in FIG. 12, the size of the wire with the wire ID = 1 is “E”, the FROM format is “JT5.5”, and the adjacent terminal is “TRUE”. In the correction factor weight list D15, the weight of the size “E” is 0.165, the weight of the FROM format “JT5.5” is 0.17, and the weight of the adjacent terminal “TRUE” is 0.208. For the electric wire with the electric wire ID = 1, the correction factor calculating unit 51 reads the weight “0.165” of the size “E” of the electric wire read from the correction factor weight list D15 shown in FIG. 18, and the FROM format “JT5.5”. The weight “0.17” and the weight “0.208” of the adjacent terminal “TRUE” are added together to calculate the wire correction factor 0.543. The correction factor calculation unit 51 associates the electric wire ID “1” with the electric wire correction factor “0.543” and registers them in the electric wire correction factor list D16.

  As shown in FIG. 6, the correction factor calculation unit 51 performs the processing from step S42 to step S44 on all the wire data set in the wire data list D11a. By the above procedure, the wire ID of the wire to be measured in the wire length measurement process (step S2) in FIG. 2 and the corresponding wire correction factor are stored in the wire correction factor list D16. Finally, the correction factor calculation unit 51 reflects the added wire correction factor list D16 in the length measurement DB of the storage unit 3 (step S45), and ends the process.

  FIG. 7 is a flowchart showing the wire correction rate display processing of the correction rate display control unit 52. The wire correction factor display process shown in FIG. 7 is performed in the result display process (step S3, step S6) shown in FIG.

  First, the correction rate display control unit 52 acquires the wire data list D11a or the wire data list D11b after manual correction and the wire correction rate list D16 (step S51). Any one of the acquired electric wire data list D11a or electric wire data list D11b is indicated and described as an electric wire data list D11.

  The correction factor display control unit 52 performs the processing from step S51 to step S52 for each electric wire, that is, for each electric wire data included in the electric wire data list D11. Of the electric wires registered in the electric wire data list D11, the electric wires to be processed in the loop processing of step S51 to step S52 are described as the processing target electric wires, and the electric wire data of the processing target electric wires are described as the processing target electric wire data.

  The correction factor display control unit 52 collates the wire ID of the processing target wire set in the processing target wire data with the wire ID set in the wire correction factor list D16. The correction rate display control unit 52 acquires the wire correction rate corresponding to the wire ID of the processing target wire from the wire correction rate list D16 (step S52). The correction factor display control unit 52 performs a visual representation of the correction factor based on the comparison between the wire correction factor acquired in step S52 and the stepwise threshold for the display of the processing target wire data (step S53). The correction factor display control unit 52 performs the processes from step S51 to step S52 for all the wires registered in the wire data list D11.

  Next, details of the correction factor expression processing performed by the correction factor display controller 52 in step S53 of FIG. 7 will be described. FIG. 8 is a flowchart showing the correction rate expression process of the correction rate display control unit 52. FIG. 20 is a diagram showing a display example of the electric wire data list D11 by the correction factor expression process of FIG. In the present embodiment, a description is given using a green gradation display as an example of visual expression. As long as it is visual, there is no limitation on the expression method, such as expressing the height of the correction rate with a different character color or changing the background pattern or shading.

  The correction rate display control unit 52 determines the wire of the processing target electric wire according to the electric wire correction factor α of the processing target electric wire and the threshold values a, b, c, d (0 ≦ a <b <c <d <e). A data display method is determined (step S61). Here, a, b, c, and d are threshold values for changing the expression of the electric wire data, and arbitrary values are set according to the distribution of the electric wire correction factor of all electric wires.

  When the wire correction factor α of the processing target wire is smaller than a, it is considered that the possibility that the wire data of the processing target wire is corrected based on the past length measurement data is considerably low. Therefore, when the correction rate display control unit 52 determines that the wire correction rate α of the processing target wire is smaller than a (step S61: 0 <α <a), as shown in the wire data A1 in FIG. The wire data of the processing target wire is displayed in a very light green color on the tool used by (No. S62).

  When the electric wire correction factor α is greater than or equal to a and smaller than b, it is considered that the electric wire data of the processing target electric wire is unlikely to be corrected. Therefore, when the correction rate display control unit 52 determines that the wire correction rate α of the processing target wire is greater than or equal to a and smaller than b (step S61: a ≦ α <b), as illustrated in the wire data A2 of FIG. Then, the wire data of the processing target wire is displayed in light green (step S63).

  When the wire correction factor α is greater than or equal to b and smaller than c, it is considered that the possibility that the wire data of the processing target wire is corrected is about 50/50. Therefore, when the correction rate display control unit 52 determines that the wire correction rate α is greater than or equal to b and smaller than c (step S61: b ≦ α <c), as illustrated in the wire data A3 in FIG. Is displayed in green (step S64).

  When the wire correction factor α is greater than or equal to c and smaller than d, it is considered that the wire data of the processing target wire is likely to be corrected. Therefore, when the correction rate display control unit 52 determines that the wire correction rate α is greater than or equal to c and smaller than d (step S61: c ≦ α <d), as illustrated in the wire data A4 in FIG. Are displayed in dark green (step S65).

  When the wire correction factor α is equal to or greater than d, the wire data of the processing target wire is considered to be highly likely to be corrected. Therefore, when the correction factor display control unit 52 determines that the electric wire correction factor α is equal to or greater than d (step S61: d ≦ α), the electric wire data of the processing target electric wire is very large as shown in the electric wire data A5 of FIG. Displayed in dark green (step S66).

  By the above processing, all the electric wire data is displayed in any colored state. That is, the operator can visually identify all the displayed electric wire data by a threshold value considering past length measurement data. As a result, the operator can instantly determine the number of wires that should be checked for correction on the target panel and the time and effort for correction, and can improve the man-hour grasping work at the manufacturing site.

  Next, correction weight calculation processing by the correction weight calculation unit 53 will be described. FIG. 9 is a flowchart showing the weight calculation process of the correction weight calculation unit 53. The weight calculation process shown in the figure is performed at an arbitrary timing after the manual correction process (step S4) shown in FIG.

  First, the correction weight calculation unit 53 acquires the wire data list D11b after manual correction (step S71). Next, the correction weight calculation unit 53 performs correction presence / absence classification processing shown in FIG. 10 described later on the electric wire data list D11b, and the corrected electric wire list in which the corrected electric wire data is set as the manually corrected electric wire data. Then, the uncorrected wire data is sorted into two lists of the corrected unwired wire list and registered in the storage unit 3 (step S72). Further, the correction weight calculation unit 53 performs a weight calculation process for each of the two lists, and obtains a correction factor weight for each component of each item (step S73). Finally, the correction weight calculation unit 53 updates the correction factor weight list D15 and the component list D17 on the length measurement DB stored in the storage unit 3 to the values after the processing in steps S72 and S73 (step S72). S74), the process is terminated.

  Next, details of the correction presence / absence classification process in step S72 of FIG. 9 will be described. FIG. 10 is a flowchart showing correction presence / absence classification processing by the correction weight calculation unit 53. The correction weight calculation unit 53 performs steps S81 to S83 on each wire data included in the wire data list D11b after manual correction acquired in step S71 of FIG. Of the electric wire data included in the electric wire data list D11b, the electric wire data to be processed in the loop processing of step S81 to step S83 is described as processing target electric wire data.

  The correction weight calculation unit 53 determines whether or not the processing target electric wire data has been manually corrected (step S81). Whether or not manual correction is performed is determined by referring to length measurement information such as the corrected wire length and route, as in step S32 of FIG.

  When the correction weight calculation unit 53 determines that the processing target wire data has been manually corrected (step S81: YES), the correction weight calculation unit 53 performs a correction list addition process for adding the processing target wire data to the corrected wire list D18 (step S81). S82). When the correction weight calculation unit 53 determines that the processing target wire data is not manually corrected (step S81: NO), the correction weight calculation unit 53 performs a correction-free list addition process for adding the processing target wire data to the correction-free wire list D19. (Step S83). The correction weight calculation unit 53 performs this series of processing on all the wire data in the wire data list D11b, and ends the processing.

  Thereby, all the electric wire data after manual correction are sorted and stored in two lists depending on the presence or absence of manual correction. FIG. 21 is a diagram illustrating an example of the wire data list D11b, FIG. 22 is a diagram illustrating an example of the corrected wire list D18, and FIG. 23 is a diagram illustrating an example of the corrected wireless list D19. When the correction presence / absence classification process shown in FIG. 10 is performed on the electric wire data list D11b shown in FIG. 21, each electric wire data in the electric wire data list D11b is converted into the corrected electric wire list D18 shown in FIG. This is sorted into the corrected non-wire list D19 shown.

  In addition, the correction weight calculation part 53 sets the electric wire data before the predetermined period in which the measurement date and time goes back from the electric wire data included in the electric wire data list D11b after the manual correction as the processing target of Steps S81 to S83. Also good. Alternatively, the correction weight calculation unit 53 determines that manual correction is not performed in step S81 when correction is not performed within the predetermined period even when correction is performed before the predetermined period retroactive from the present. May be.

  Next, details of the weight calculation process in step S73 of FIG. 9 will be described. FIG. 11 is a flowchart showing the weight calculation process by the correction weight calculation unit 53.

  The correction weight calculation unit 53 performs the processing from step S91 to step S96 for each item included in the component list D17. An item to be processed in each loop process is referred to as a process target item. Moreover, the correction weight calculation part 53 performs the process of step S91-step S93 with respect to each of the correction | amendment electric wire list | wrist D18 and the correction | amendment non-electric wire list | wrist D19. The corrected wired list D18 or the corrected non-wire list D19 that is the processing target in the loop processing of Step S91 to Step S93 is described as the processing target list.

  The correction weight calculation unit 53 performs a merging process between the processing target list and the processing target item in the component list D17 (step S91). At this time, the correction weight calculation unit 53 merges the processing target item and the length measurement date / time information so that the total period can be controlled.

  FIG. 24 is a diagram illustrating an example of the component list D17. Here, first, the correction weight calculation unit 53 refers to the length measurement date and time set in the component list D17 in the figure, and extracts only data that falls within a preset aggregation period. FIG. 25 is a diagram illustrating an example of the component list D17 in which only data that has entered the aggregation period is extracted. This figure shows the result of extracting data from the component list D17 shown in FIG. As a result, the length measurement tool has been improved and improved, and it is possible to cope with the case where there is no need to correct the wires that had to be corrected in the past. It is possible to prevent the electric wire list D18 from being listed.

  FIG. 26 is a diagram showing the component list D17 after merging. The component list D17 shown in the figure shows the result of performing the merge process of step S91 on the component list shown in FIG. 25 and the corrected wire list D18 shown in FIG. That is, the correction weight calculation unit 53 sets the processing target item set in the processing target wire data of the corrected wired list D18 shown in FIG. 22 and the processing target item and length measurement date and time of the component list shown in FIG. Add a combination of measurement date and time values. The correction weight calculation unit 53 performs the same process even when the processing target list is the corrected no-wire list D19. At the end of the merge process, the correction weight calculation unit 53 registers and updates the component list D17 to which the information on the processing target list is added in the length measurement DB of the storage unit 3.

  Next, as illustrated in FIG. 11, the correction weight calculation unit 53 performs a component totaling process for totaling the number of wire data for each component of the processing target item with respect to the merged component list D17 (step S92). FIG. 27 is a diagram illustrating a result of performing the component totaling process for each processing target item using the component list D17 illustrated in FIG.

  Next, as illustrated in FIG. 11, the correction weight calculation unit 53 calculates the ratio of each component in the processing target item using the number of wire data for each component calculated in step S92 (step S93). The ratio of the constituent elements is obtained by dividing the number of constituent elements in the processing target item by the total number of constituent elements of the processing target item. FIG. 28 is a diagram illustrating a result of calculating a component ratio for each processing target item with respect to the component aggregation result illustrated in FIG. 27. Thereby, the distribution for each component in the target counting period can be obtained for each of the corrected wired and the corrected non-wired wire.

  As illustrated in FIG. 11, the correction weight calculation unit 53 performs the processing from step S91 to step S93 on each of the corrected wire list D18 and the corrected wireless list D19. Thereby, the number of components and the ratio for each component for each correction can be obtained.

  Subsequently, the correction weight calculation unit 53 corrects each component of the processing target item using the number and proportion of the processing target item with correction and the number and ratio of the processing target item without correction. The rate is obtained (step S94). The correction rate is obtained by dividing the number of components with correction by the sum of the number of components with correction and the number of components without correction. FIG. 29 is a diagram illustrating a result of the correction rate calculation process performed on the list of FIG.

  Next, as shown in FIG. 11, the correction weight calculation unit 53 calculates the correction factor weight of each component of the processing target item using the component ratio and the correction factor of the processing target item obtained so far. (Step S95). The weight of the correction factor of the component is obtained by multiplying the component ratio of the component by the correction factor. Finally, the correction weight calculation unit 53 performs a correction weight calculation process of adding the correction factor weights obtained in step S95 to the correction factor weight list D15 (step S96). The correction weight calculation unit 53 adds the correction factor weight for each component of each item to the correction factor weight list D15 by performing the above process on all items. FIG. 18 is a diagram showing the correction factor weight list D15 in which the correction factor weights are obtained as a result of performing the correction factor weight calculation processing in step S95 on FIG. 28 and FIG.

  In the above description, in order to calculate the weight of the wire correction, each component of the wire data is decomposed and the weight is calculated. However, an actual wire may need to be corrected by a combination of specific components. Since this embodiment also functions with a combination of two or more specific items or components, such influence can be taken into consideration.

  FIG. 30 is an example of a component list in the case where the combination of the FROM format and the TO format and the combination of the relationship between the adjacent terminals and the same stage affect the correction of the electric wires. Constituent elements other than the determined combination are disassembled for each constituent element in the same manner as described above.

  As described above, the correction-unnecessary electric wire list creation unit 43 of the electric wire length correction work support device 1 includes information on the connection source device and the connection destination device of the wire, information on the position of each of these devices, and the specification of the wire. Based on the information and the wire data including the setting contents of at least some of the items of the route information through which the wire passes, and information on whether or not the correction was made to the measurement result of the wire, A combination of components that is the setting content of the item of the electric wire that does not need correction is acquired. The correction unnecessary wire list creation unit 43 is an example of a correction unnecessary component acquisition unit. The electric wire data may include at least information on the connection source device and the connection destination device.

  The correction-unnecessary wire detection unit 41 compares the wire data of each of the one or more work target wires included in the wire data list with the combination of the components acquired by the correction-unnecessary wire list creation unit 43, and does not require correction. Detects the target electric wire. The electric wire list display control unit 42 does not display the electric wire data of the electric wires detected by the correction unnecessary electric wire detection unit 41 as being unnecessary for the display of the electric wire data included in the electric wire data list, or The display is controlled in a manner that indicates that correction is unnecessary.

  The correction weight calculation unit 53 is for each item or each combination of items based on the wire data of the wire measured in the past and information on whether or not the length measurement result of the wire has been corrected. , Calculating the correction factor that is the ratio of the component existing ratio and the correction of the component electric wire, and using the calculated presence ratio and correction factor, the correction weight of the component element is quantified Create a list.

  The correction factor calculation unit 51 reads the correction weights of the components set in the electric wire data of each of the one or more work target wires included in the wire data list from the list, and determines the correction possibility of the work target wires. Based on the sum of the correction weights read for the electric wire data of the electric wire, the correction possibility of the electric wire to be worked is calculated. The correction factor display control unit 52 displays each of the electric wire data included in the electric wire data list in a manner representing the possibility of correction of the electric wire data.

  Electric wire processing workers need to check the appliances, electric wire specifications, and wiring paths for switchboards with thousands of electric wires one by one, and determine whether the results of automatic length measurement are acceptable or whether correction is necessary. There is. When the labor and the degree of work required for the correction of automatic length measurement are indicated by numerical values, it is difficult to grasp the number of wires, the feeling of scale, and the labor required for the correction work. In addition, it is burdensome to determine whether or not correction is performed, and it takes time and man-hours to grasp the scale and degree of correction work. At the wire processing site, there is a need for quickly grasping the possibility of correcting each wire data and correcting the data as necessary.

  According to at least one embodiment described above, the wire length correction work support device 1 includes the correction necessity management unit 4 to detect an electric wire that does not need to be corrected with respect to the length measurement result of the wire. The correction necessity management unit 4 uses this detection result to display a non-displayable or difficult-to-see wire for an electric wire that does not need correction, or to display an easy-to-understand indication of the degree to which correction is required for an electric wire that requires correction. You can do it. Specifically, by detecting the wiring route that can be generated mechanically, the wire length that does not need to be corrected, listing them in advance, and clearly indicating such wires to the operator or removing them from the screen display This makes it possible to emphasize electric wires that need to be corrected for automatic length measurement results. Therefore, it is possible to reduce the work load of correcting the wire length in consideration of the positional relationship of the wire connection tool and duct, the wire specification, the housing specification, etc. performed by the wire processing worker, and to support the work. Become. In addition, since the electric wire data is represented in a list format, if it is confirmed sequentially from the top, the correction work and the confirmation work are unlikely to occur.

  Moreover, according to at least one embodiment described above, the wire length correction work support device 1 includes the correction rate management unit 5 so as to clearly indicate the possibility that the length measurement result needs to be corrected step by step.

In other words, you can quickly know how much effort is required on which board. Therefore, it is easy to make a work plan, and it is possible to support the determination of whether it is in time for delivery. In addition, the state of each electric wire is distinguished using an index calculated based on past measurement data. Thereby, the state of the displayed electric wire data can be displayed in consideration of the worker's past experience.
