Description

  The present invention mainly relates to a system for supporting a check operation of an electric circuit of a wire harness.

  In vehicles such as automobiles, electronic devices, and the like, wire harnesses are used to transmit electricity and signals between the components. The wire harness includes a plurality of electric wires connected to form a predetermined electric circuit.

In the process of commercialization, the wire harness is checked for errors in its electrical circuit. For example, Patent Document 1 discloses an inspection apparatus that sequentially inspects a plurality of electric circuits included in a wire harness by attaching electrodes to both ends of the electric circuit of the wire harness and passing a current through the electrodes.
Japanese Patent Laid-Open No. 9-80104

  In recent years, with the progress of computerization of equipment and the development of information technology, products such as automobiles and electric appliances have been equipped with a large number of electronic devices. In addition, in order to respond to the diversification of user preferences and lifestyles, manufacturers that supply products have often prepared a large number of product lineups with different electronic devices and grades of devices.

  In order to cope with such a situation, for example, in an automobile, a wire harness is configured to be divided into a plurality of parts such as an instrument panel harness, a door harness, and a floor harness, and the parts are connected to each other by connector connection or the like. Are generally used, and each part has a plurality of specifications (the presence / absence of options, destination (shipment area), vehicle type / grade, engine type, left / right difference in steering wheel, etc., or a combination thereof). The use of things has increased. According to this split-type wire harness, even if the component device of the product is changed, it can be dealt with by simply exchanging the corresponding part of the wire harness with a different specification.

  Here, in general, in the inspection of a wire harness, there is a need to actually assemble a wire harness for one vehicle and check an electric circuit in a state close to an actual product. Therefore, in order to meet the above-described needs in the split wire harness, the electric circuit is checked in a state where a plurality of parts are actually connected.

  However, when the number of divided parts of the wire harness and the number of specifications for each part are large, the number of connection combinations necessary for the check operation becomes enormous when attempting to check all the parts and the electrical circuits of all the specifications. Therefore, in this case, it is not practical to perform the circuit check work for all combinations because it takes too much time and man-hours.

  The present invention has been made under the circumstances described above, and its main purpose is to provide electric circuits for all parts and all specifications with a small number of connection combinations even when the number of divided parts of the wire harness and the number of specifications for each part are large. It is an object of the present invention to provide a system that supports a circuit check operation so that the circuit can be substantially checked.

Means and effects for solving the problems

  The problems to be solved by the present invention are as described above. Next, means for solving the problems and the effects thereof will be described.

  According to a first aspect of the present invention, a wire harness circuit check work support system having the following configuration is provided. That is, a circuit check for checking the circuit operation of a wire harness that is divided into a plurality of parts and each has a component circuit and that has one or more specifications for each part in a state where the parts are connected to each other. It is a wire harness circuit check work support system that supports work. The wire harness circuit check work support system includes a storage unit and a processing unit. The storage unit can store configuration circuit information including information on a configuration circuit included in each specification of the part, and circuit operation check record information of the configuration circuit of each specification. When a check specification, which is a specification of each part used in the circuit check work, is input to the processing unit, (1) from among the constituent circuits included in the check specification, the operation can be checked in the circuit check work An actual checked record process for identifying a checked component circuit based on the component circuit information and recording the actually checked information in the circuit operation check record information of the actually checked component circuit; (2) other than the check specification Based on the configuration circuit information, a substantially checked configuration circuit that can be substantially checked by checking the actually checked configuration circuit is selected from the configuration circuits included in the specifications of the configuration circuit. And a substantially checked recording process for recording the substantially checked information in the circuit operation check recorded information. It is configured.

  In the wire harness circuit check work support system, the processing unit is a specification other than the check specification in the substantial checked recording process, and the configuration circuit includes a configuration circuit of the check specification. Preferably, a circuit inclusion specification is specified, and a component circuit that is common to the actually checked component circuit among the component circuits included in the circuit inclusion specification is specified as the substantially checked component circuit.

  As a result, the substantially checked component circuit in the specification other than the check specification can be accurately specified, and the circuit check operation can be completed with a small number of times while maintaining the reliability of the circuit check operation.

  In the wire harness circuit check work support system, it is preferable that the mark of the actually checked information is different from the mark of the substantially checked information.

  This makes it possible to determine which component circuit was actually checked by using the mark, which can be used for subsequent examination.

  In the wire harness circuit check work support system, the processing unit is actually checked in the circuit operation check record information in the circuit operation check record information in the actual checked recording process and the substantially checked recorded process. It is preferable to record whether the actual check has been completed.

  As a result, the user can easily consider a more efficient combination of check specifications with reference to the record.

  In the wire harness circuit check work support system, the processing unit includes the number of constituent circuits in which at least one of the actually checked information and the substantially checked information is recorded in the circuit operation check record information of the storage unit. It is preferable to be configured so that the count result can be output.

  Thereby, the user can obtain useful information such as the progress status of the wire harness circuit check operation with reference to the count result.

  In the wire harness circuit check work support system, the processing unit counts the number of constituent circuits in which neither actual checked information nor actual checked information is recorded in the circuit operation check record information of the storage unit. The count result is preferably outputable.

  Thereby, the user can obtain useful information such as the progress status of the wire harness circuit check work with reference to the count result.

That is, a combination of check specifications for each part is input to the wire harness circuit check work support system for each circuit check work, and a combination of check specifications for the next circuit check work based on the output result of the system This is repeated until the actually checked information or the substantially checked information is recorded in the circuit operation check record information of all the constituent circuits in all parts and all specifications.

  As a result, the user can easily determine a procedure by which the check can be completed for all the components and all the configuration circuits with a small number of circuit check operations with reference to the output result of the system.

  According to the 3rd viewpoint of this invention, the wire harness circuit check method which performs the circuit check of a wire harness according to the procedure determined by the said procedure determination method is provided.

  Thereby, the check can be completed for all the components and all the constituent circuits of all specifications with a small number of circuit check operations. Therefore, the time and man-hours required for work can be significantly reduced.

There is provided a program for executing an input step to be input by a user and a recording step for performing the actual checked recording processing and the actual checked recording processing.

  As a result, it is possible to provide a system capable of providing effective support when a user determines a combination of check specifications that can at least substantially check all parts and all configuration circuit components with a small number of connection combinations. .

  Next, embodiments of the invention will be described with reference to the drawings. FIG. 1 schematically shows an example of an audio system as a mounted device (component device) installed in an automobile using the wire harness of the present embodiment. As shown in FIG. 1, the audio system 5 includes an amplifier 21 that amplifies an audio signal from, for example, a music player or a radio receiver, a right speaker 22 and a left speaker 23 for outputting audio, and an electric signal. A junction box 24 for relaying.

  In addition to the audio system 5 typically shown in FIG. 1, the automobile includes a number of on-board devices (systems) (not shown) such as a fuel pump, an electronic control unit (ECU), an alternator, and a battery. And the wire harness 2 with which this motor vehicle is provided has many parts (large parts) divided | segmented for every mounted apparatus (system). In FIG. 1, a large part (hereinafter referred to as “audio system part”) of the wire harness 2 corresponding to the audio system 5 is representatively illustrated by reference numeral 3.

  As shown in FIG. 1, the audio system part 3 of the wire harness 2 electrically connects the right speaker 22, the left speaker 23, the junction box 24 and the amplifier 21, thereby enabling transmission and reception of electrical signals. It has become.

  The audio system part 3 of the wire harness 2 is further divided into a first part 11, a second part 12, and a third part 13. Each of the three parts 11 to 13 includes a plurality of electric wires, thereby realizing a predetermined constituent circuit. With this configuration, the plurality of parts 11 to 13 are connected to each other by the connectors 31 and 32, so that the constituent circuits are also connected to each other, and electrical signals can be exchanged between the devices 21 to 24.

  The automobile using the wire harness 2 of the present embodiment has a number of product specifications such as its grade and right handle specification / left handle specification. And between vehicles with different product specifications, the type, number, mounting position, and the like of each mounted device are slightly different. Also in the audio system 5 shown in FIG. 1, if the product specifications of the automobile are different, for example, the type of the amplifier 21, the types and number of the right speakers 22 and the left speakers 23, the mounting positions of the devices 21 to 24, and the like are different. It will be.

  Correspondingly, each of the first part 11, the second part 12, and the third part 13 in the audio system part 3 of the wire harness 2 has a plurality of specifications and product numbers based thereon. Specifically, the first part 11 has six specifications A to F, the second part 12 has six specifications G to L, and the third part 13 has four specifications M to P. Has one specification.

  When specifications differ in each part 11-13, also a part of circuit which is formed with the electric wire differs in part or all. However, depending on the specification (part number) arrangement method, it may be possible that the configuration circuit is the same even if the specification is different. The details of the constituent circuits included in each specification will be described later.

  As described above, by appropriately selecting and combining the specifications of the three parts 11 to 13 in the audio system 5, it is possible to appropriately exchange signals between devices even if the types and numbers of the devices 21 to 24 are different. Can be done. And the wire harness 2 of this embodiment is divided | segmented into several site | parts similarly about the large site | part corresponding to mounting apparatuses other than the audio system 5, and each site | part has several specifications. As a result, a wide variety of on-board devices such as the audio system 5 can be made in accordance with the different product specifications of the automobile.

  And the circuit check operation | work which test | inspects the error etc. of an electric circuit in the wire harness 2 of this embodiment actually assembles the wire harness 2 for one vehicle, and checks an electric circuit in the same state as an actual product. To do. That is, the wire harness 2 selects appropriate specifications for all parts of the audio system 5 and other mounted devices, and checks the electric circuit in a state where the parts are actually connected.

  Next, the configuration of the wire harness circuit check work support system for supporting the circuit check work will be described with reference to FIG. FIG. 2 is a functional block diagram of the wire harness circuit check work support system.

  A wire harness circuit check work support system (hereinafter simply referred to as a system) 51 of this embodiment shown in FIG. 2 is configured using a general-purpose personal computer (PC), and includes a keyboard 52, a mouse 53, a center An arithmetic processing unit (CPU) 54, a main memory 55, a hard disk drive 56, and a display 57 are provided. The main memory 55 and the hard disk drive 56 are configured to store various information. The CPU 54 is configured to perform various calculations and controls.

  The hard disk drive 56 is installed with a program (work support program) for causing the PC to function as the wire harness circuit check work support system 51. This installation is performed using an appropriate recording medium (for example, a CD-ROM) in which the work support program is recorded.

  Next, configuration circuit information and circuit operation check record information stored in the main memory 55 or the hard disk drive 56 of the system 51 will be described with reference to FIG. FIG. 3 conceptually shows an example of the contents stored in the main memory 55 or the hard disk drive 56.

  The configuration circuit information is information describing which specifications each of the divided parts of the wire harness 2 have, and which configuration circuit each specification has.

  For example, the upper table in FIG. 3 shows that the first part 11 of the audio system part 3 of the wire harness 2 has six specifications A to F, and which constituent circuit each specification A to F has. Is shown by a circle. For example, in the specification A column of the first part 11, 3 and 5 are included among the constituent circuits 1 to 6, but 1, 2, 4 and 6 are not included.

  Similarly, in the center table of FIG. 3, the second part 12 of the audio system part 3 has six specifications G to L, and each of the specifications G to L is one of the constituent circuits 1 to 6. It indicates whether a constituent circuit is provided. In the lower table of FIG. 3, the third part 13 indicates that the four specifications M to P are included, and each of the specifications M to P includes which of the constituent circuits 1 to 6 is included. It expresses.

  Information corresponding to the contents of such a table is prepared in advance by a user based on a data sheet, wiring diagram, etc. of the specifications of each part, and is stored in the main memory 55 or the hard disk drive 56 as component circuit information. Keep it.

  Accordingly, by referring to the configuration circuit information, for example, in the first part 11 (the upper table in FIG. 3), the configuration A is completely different between the specification A and the specification C, while the specification A and the specification B Then, it can be seen that the constituent circuits are exactly the same. In addition, it can be seen that the specifications A and F are partially identical in configuration circuit (configuration circuit 5). In addition, for example, the specification A of the first part 11 (upper table in FIG. 3) and the specification J of the second part 12 (center table in FIG. 3) have the configuration circuits 3 and 5 in common. Etc.

  Further, the main memory 55 or the hard disk drive 56 is provided with a circuit indicating that the circuit operation is actually checked or substantially checked for each of the constituent circuits included in the specifications A to F, G to L, and M to P described above. It can be recorded as operation check record information. That is, the circles attached in the conceptual diagram of FIG. 3 mean that each specification has a corresponding constituent circuit, and at the same time indicate that the constituent circuit is unchecked. Then, in the process of recording the fact that the actual check has been completed or the fact that the check has been completed, in the conceptual diagram of FIG. 3, in each of the squares that are circled in the three tables, a circle that means unchecked is added. This is equivalent to overwriting recording with another mark that has been actually checked or actually checked.

  Further, in the present embodiment, information on how many times the circuit check operation has been actually checked or substantially checked can also be recorded as circuit operation check record information.

  Although only the audio system part 3 is shown in FIG. 3, the circuit configuration information is similarly created in advance and stored in the main memory 55 or the like for each part of the wire harness 2 corresponding to other mounted devices. The circuit operation check record information can also be stored in the main memory 55 or the like.

  Using this wire harness circuit check work support system 51, the circuit check work is repeated until all the constituent circuits included in all the specifications of all parts of the wire harness 2 are checked (actually or substantially). Hereinafter, it demonstrates in detail, referring centering on the flowchart of FIG.

  When the work support program installed in the system 51 is executed, an appropriate initialization process is first performed. This initialization process includes a process (S101 in FIG. 4) for resetting the circuit operation check information to be unchecked for all the constituent circuits included in all the specifications of all parts.

  After this initialization, the system 51 receives an input of specifications used in the circuit check work (S102). First, in the first circuit check operation, the user operates the keyboard 52 and the mouse 53 to input to the system 51 which specification to select for each part of the wire harness 2. In this explanation, in the audio system part 3 of the wire harness 2, it is assumed that the first part 11 selects and inputs the specification A, the second part 12 selects the specification J, and the third part 13 selects and inputs the specification M. . Of course, the specification is selected and input in the same manner in the parts corresponding to the mounted devices other than the audio system part 3.

  In the present specification, the specification of each part used in the circuit check operation is referred to as “check specification”. In this circuit check operation, the check specification of the first part 11 is the specification A, the check specification of the second part 12 is the specification J, and the check specification of the third part 13 is the specification M.

  When the check specifications A, J, and M are input by the user, the system 51 starts the actually checked recording process (S103). In this actually checked recording process, first, among the check circuits A, J, and M, the actually checked component circuit that can be considered to have been checked for operation in the current (first) circuit check operation is used. decide.

  This will be specifically described. As shown in FIG. 3, the constituent circuits included in the check specification A of the first part 11 are 3, 5 and the constituent circuits included in the check specification J of the second part 12 are 1, 3, 5, and the third part The configuration circuits included in the 13 check specifications M are 1, 3, and 5. Therefore, when the parts 11 to 13 of this specification are combined, the constituent circuits 3 and 5 function normally because all the parts 11 to 13 are provided, but the constituent circuit 1 is not connected to the first part 11 (check specification). A) is not equipped.

  Therefore, in the connection combination of the circuit check work this time, the configuration circuit 1 of the second part 12 (check specification J) and the configuration circuit 1 of the third part 13 (check specification M) are discarded configuration circuits that do not substantially function. Therefore, it cannot be assumed that the circuit operation can be checked.

  In view of this point, the system 51 substantially functions in the combination of the check specifications A, J, and M from the constituent circuits included in each of the check specifications A, J, and M based on the configuration circuit information (FIG. 3). A circuit that excludes the discarded configuration circuit is determined as the actually checked configuration circuit.

  For example, paying attention to the check specification J of the second part 12, the configuration circuits included in the check specification J are 1, 3, and 5. Of these, the check specification A of the first part 11 and the check specification M of the second part 12 are included. However, there are only 3 and 5 component circuits (component circuit 1 is discarded). Therefore, in the check specification J, the constituent circuits 3 and 5 are determined as actually checked constituent circuits. Similarly, regarding the check specification M of the third part 13, only the component circuits 3 and 5 among the component circuits 1, 3 and 5 included therein are determined as actually checked component circuits. The configuration circuits 3 and 5 of the check specification A of the first part 11 are all determined as actually checked configuration circuits.

  When the actually checked component circuits are determined for all the check specifications A, J, and M, in the circuit operation check record information, an actually checked mark is recorded in the actually checked component circuit. In the table of FIG. 3, the actually checked marks are recorded in the circles of the configuration circuits 3 and 5 of the specification A, the configuration circuits 3 and 5 of the specification J, and the configuration circuits 3 and 5 of the specification M, respectively. Will be. Thus, the actually checked recording process (S103) is completed.

  The stored contents after the actually checked recording process are shown in FIG. In FIG. 5, the circle mark (not checked) at the corresponding location is deleted, and information (“1” mark) indicating that the check has actually been performed by the first circuit check operation is recorded. Yes.

  Subsequently, a substantially checked recording process (S104) is performed. In the actual checked recording process, first, specifications (circuit inclusion specifications) that are specifications other than the check specifications A, J, and M and that include the check configuration component circuit are determined.

  For example, in the first part 11 (the upper table in FIG. 5), the check circuit A has 3 and 5 constituent circuits, and the other specifications (circuit inclusion specifications) include B. The specification F includes the constituent circuit 5, but does not include the constituent circuit 3, and thus is not a circuit inclusion specification.

  Similarly, in the second part 12 (the center table in FIG. 5), the configuration circuits included in the check specification J are 1, 3, and 5, and the specifications including this configuration circuit are K and L. Specifications K and L become circuit inclusion specifications. In the third part (the lower table in FIG. 5), the configuration circuits included in the check specification M are 1, 3, and 5, and the circuit inclusion specification including this configuration circuit is N.

  After the circuit inclusion specifications B, K, L, and N are determined as described above, in the component circuits included in the circuit inclusion specifications B, K, L, and N, the actually checked component circuits are substantially checked. The component circuit (substantially checked component circuit) that has been checked is determined. The substantially checked component circuit is a component circuit that is common to the actually checked component circuit among the component circuits included in the circuit inclusion specifications B, K, L, and N.

  For example, in the second part 12 (the center table in FIG. 5), the circuit inclusion specifications K have 1, 3, 5, and 5 of these are actually checked component circuits (in the table cell). This is the same as the circuit in which “1” is recorded. Therefore, among the constituent circuits 1, 3, and 5 of the circuit inclusion specification K, the constituent circuits 3 and 5 are determined to be substantially checked constituent circuits. Similarly, for the circuit inclusion specifications B, L, and N, the constituent circuits 3 and 5 are determined to be substantially checked constituent circuits.

  When the substantially checked constituent circuits are determined for all the circuit inclusion specifications B, K, L, and N, in the circuit operation check record information, a substantially checked mark is recorded in the substantially checked constituent circuits. In the table of FIG. 5, a substantially checked mark is recorded in the circles of the constituent circuits 3 and 5 of the circuit inclusion specifications B, K, L, and N, respectively. Thus, the substantially checked recording process (S104 in FIG. 4) is completed.

  FIG. 6 shows the storage contents after the real checked recording process. In FIG. 6, the circle mark (not checked) at the corresponding location is deleted, and information (“1 ′” mark) indicating that the check has been substantially performed by the first circuit check operation is recorded. ing. In addition, the dash “′” attached to the numbers in the table of FIG. 6 and the like indicates that the actual check was not performed but the check could be made substantially. As described above, it is preferable to select different marks so that the actual check and the actual check can be distinguished from each other, so that it is possible to determine which check is actually performed later.

  The above processing is related to the audio system part 3, but the same process is performed in parts corresponding to mounted devices other than the audio system part 3, and the circuit operation check record information is actually checked or substantially checked. Checked is recorded.

  Thereafter, the system 51 outputs the stored contents of the main memory 55 or the hard disk drive 56 such as circuit operation check record information in an appropriate format (S105 in FIG. 4). As the output method, for example, the content shown in FIG. 6 is displayed on the display 57, printed from a printer connected to a PC, or a file in a format that can be read by a spreadsheet application software. It is conceivable to store the data in 56.

  At the time of this output, the number of component circuits in which either actual check or substantial check is recorded is counted in the circuit operation check record information, and the count result (completed number) is also output. I am doing so. For example, in the audio system part 3 (FIG. 6), the number of component circuits that are actually checked or substantially checked (the number of cells on which “1” or “1 ′” is recorded) is 14 pieces. Therefore, for example, “Audio system part; 14 units completed” is output.

  Further, a ratio (check completion rate) obtained by dividing the number of completions by the number of all constituent circuits is also output. For example, in the audio system part 3 (FIG. 6), the number of all the constituent circuits (the number of circles in FIG. 3) is 42 and 14 / 42≈0.3333. "33.33%" etc. are output in percentage format.

  Of course, the count result and the check completion rate are also output for parts other than the audio system part 3. Further, the total number of completed parts and the check completion rate in all parts are also output.

  In this embodiment, in addition to the completed number, the number of component circuits that are not actually checked or substantially checked is recorded in the circuit operation check record information, and the count result (unchecked number) is calculated. It is configured to output. Further, a ratio (unchecked rate) obtained by dividing the number of unchecked by the number of all constituent circuits is also output.

  With the above processing (S102 to S105 in FIG. 4), the processing for one circuit check operation is completed, and the user performs each part in the next (second) circuit operation check operation based on the output result in S105. Then, consider which specifications should be selected or whether the circuit operation check work should be completed.

  After the output processing in S105, the system 51 inquires whether or not to input the next circuit check work by, for example, displaying an inquiry window on the display 57 (S106). In this explanation, it is assumed that the user has selected to input again in response to the inquiry. Then, the process returns to S102, and the system 51 receives an input of the check specification in the second circuit check work from the user.

  As in the first time, when the user inputs the check specification selected in the second circuit operation check work to the system 51 (S102), the system 51 performs the actual checked recording process (S103) and the actual checked recording. Processing (S104) is performed and the result is output (S105). In FIG. 7, specifications F, L, and N are input as check specifications for the second circuit operation check work, and after the actual checked recording process and the actual checked recording process are further performed from the state of FIG. The stored contents are shown. As shown in FIG. 7, “2” is recorded in the actually checked component circuit, which indicates that the circuit circuit has been checked in the second circuit operation check work. Further, “2 ′” is recorded in the substantially checked component circuit, which indicates that the second circuit operation check operation has been substantially checked.

  On the user side, the check specification is input to the system 51 and the actual checked recording process and the actual checked recording process are performed, and then the result is output (S102 to S105). Is repeated until the actual operation check or the actual check operation is recorded in the circuit operation check record information of all the constituent circuits in all the parts of the wire harness 2 and all the specifications.

  FIG. 8 shows a case where specifications C, I, and O are input as check specifications for the third circuit operation check work, and specifications E, G, and P are input as check specifications for the fourth circuit operation check work. The contents are shown. In the state of FIG. 8, the unchecked circle is erased and numbers or numbers with dashes are recorded for all parts in the audio system part 3 and all the constituent circuits in all specifications.

  When the user confirms that all the constituent circuits are actually checked / substantially checked as described above by looking at the output result of S105, the user performs the next circuit check operation in the process of S106 of FIG. Select not to enter. Then, the loop of S102 to S106 is exited and the execution of the program ends.

  As described above, the user can easily obtain a combination of specifications that can substantially check all parts and all specifications with a small number of circuit check operations. For example, in the above-described example of the audio system part 3, the specifications A, J, and M are used as the first check specification, the specifications F, L, and N are used as the second check specification, and the specifications C and C are used as the third check specification. If you follow the procedure of selecting specifications E, G, and P as the check specifications for I, O, and 4th time, check the circuit operation for all 4 parts of the audio system part 3 and the constituent circuits of all specifications. At least substantially all can be checked in the work.

  This is based on the required number of circuit operation check operations when the procedure is determined so that all combinations of specifications are checked brute force (product of the number of specifications of each part 11-13, 6 × 6 × 4 = 144 times). Means that all the constituent circuits can be checked at least substantially in a very small number of times. Therefore, the man-hours and time required for the circuit operation check of the wire harness 2 can be compressed very well.

  As described above, the wire harness circuit check work support system 51 of this embodiment includes the main memory 55, the hard disk drive 56, and the CPU 54. In the main memory 55 or the hard disk drive 56, as shown in FIG. 3, component circuit information including component circuit information included in each specification of the parts 11 to 13 of the wire harness 2 and component circuits of each specification are stored. Circuit operation check record information can be stored. When the check specifications, which are the specifications of each part used in the circuit check work, are input to the system 51 (S102 in FIG. 4), the actual checked recording process (S103) and the substantially checked recording process ( S104) is performed for each part 11 to 13 and for each large part (each system), and the storage contents (for example, circuit operation check record information) of the main memory 55 or the hard disk drive 56 are stored. Output is possible (S105 in FIG. 4).

  In the actual checked recording process (S103), the actually checked configuration circuit that can check the operation in the circuit check operation is specified based on the configuration circuit information from the configuration circuits included in the check specification input in S102. Then, as shown in FIG. 5, the actual check completion is recorded in the circuit operation check record information of the actually checked component circuit.

  In the substantially checked recording process (S104 in FIG. 4), the actually checked configuration that can be substantially checked by checking the actually checked configuration circuit from among the configuration circuits included in the specifications other than the check specification. A circuit is specified based on the component circuit information, and as shown in FIG. 6, “substantially checked” is recorded in the circuit operation check record information of the substantially checked component circuit.

  With this configuration, the user can easily determine a combination of check specifications that can at least substantially check all the components and all the configuration circuits with a small number of connection combinations by examining the output result of the system 51. . Therefore, the circuit check work can be completed with a small number of times, and the time and man-hours required for the work can be significantly reduced.

  In the actual checked recording process (S103), the system 51 of the present embodiment, for example, in the central table of FIG. 5, from the constituent circuits 1, 3, 5 included in the input check specification J, A configuration circuit (3, 5) excluding the configuration circuit 1 which is a discarded configuration circuit that does not substantially function in the combination of the check specifications A, J, and M is specified as the actually checked configuration circuit, and this actual checked The configuration circuits 3 and 5 are configured to record “1” indicating that the actual check has been completed.

  In other words, among the constituent circuits 1, 3, and 5 provided in the input check specification J, the constituent circuits 3 and 5 that are also provided in common with the check specifications A and M of other parts After specifying as an actually checked component circuit, “1” indicating that the component has been checked is recorded in the actually checked component circuits 3 and 5.

  With this configuration, it is possible to prevent a configuration circuit that is not substantially functioning (a discard configuration circuit) from being actually checked, and to improve the reliability of the circuit check operation.

  Further, in the system 51 of the present embodiment, in the substantially checked recording process (S104 in FIG. 4), for example, specifications (G, H, I, K, etc.) other than the check specification J in the central table of FIG. From L), circuit inclusion specifications K and L, which are specifications in which the constituent circuits include the constituent circuits 1, 3, and 5 of the check specification J, are specified. Of the constituent circuits 1, 3, and 5 included in the circuit inclusion specifications K and L, the constituent circuits 3 and 5 that are common to the actually checked constituent circuits 3 and 5 are used as the substantially checked constituent circuits. Specifically, “1 ′” indicating that the substantial check has been completed is recorded in the substantial checked component circuits 3 and 5.

  With this configuration, the substantially checked component circuit can be accurately specified, so that the circuit check operation can be completed with a small number of times while maintaining the reliability of the circuit check operation.

  In the system 51 of this embodiment, the marks recorded in the circuit operation check record information are different between the actually checked information and the substantially checked information. That is, in the table of FIG. 8, the presence or absence of dashes is made different as numbers without dashes when actually checked and as numbers with dashes when actually checked.

  This makes it possible to determine whether or not the component circuit has actually been checked based on the mark, which can be used for subsequent examination.

  Further, the system 51 according to the present embodiment includes the circuit operation check recording information in the actual checked recording process (S103 in FIG. 4) and the actual checked recording process (S104), for example, as shown in FIG. The number of times the component circuit is actually checked or substantially checked in the circuit check operation is also recorded.

  With this configuration, the user can easily examine the possibility of combining more efficient check specifications with reference to the record.

  In the result output process (S105 in FIG. 4), the system 51 according to the present embodiment counts the number of constituent circuits in which at least one of the actual check and the actual check is recorded in the circuit operation check record information. The number of completions as the count result can be output.

  Further, in the result output process (S105), the system 51 of the present embodiment counts the number of component circuits that are not recorded in the circuit operation check record information as being actually checked or substantially checked, and the count result is used as the count result. A certain number of unchecked items can be output.

  With this configuration, the user can obtain useful information such as the progress status of the wire harness circuit check operation with reference to the completed number and the unchecked number.

  In the present embodiment, the circuit check work procedure of the wire harness 2 is performed by inputting a combination of check specifications for each part to the system 51 for each circuit check work (S102) and outputting the system 51. Based on the result (S105), the operation of determining the combination of the check specifications of the next circuit check operation is recorded in the circuit operation check record information of all the constituent circuits in all the parts and in all specifications. It is determined by repeating until it reaches a state (for example, the state of FIG. 8).

  By this method, the user can easily determine a procedure that can be completed without checking all the components and all the configuration circuits with a small number of circuit check operations with reference to the output result of the system 51. .

  In addition, the wire harness circuit check method for which the procedure is determined in this way can significantly reduce the time and man-hours required for the circuit check operation.

  Further, the work support program installed in the PC in this embodiment is an input step (S102 in FIG. 4) that allows the PC including the main memory 55, the hard disk drive 56, the CPU 54, and the like to input the check specifications of each part to the user. ) And recording steps (S102 and S103 in FIG. 4) for executing the actual checked recording process and the actual checked recording process.

  Thus, it is possible to provide a system 51 capable of effectively assisting a user in determining a combination of check specifications that can check at least substantially all component parts and all specification component circuits with a small number of connection combinations. it can.

  Although the preferred embodiment of the present invention has been described above, the above configuration can be changed as follows, for example.

  The format for storing the configuration circuit information and the circuit operation check record information in the main memory 55 and the hard disk drive 56 is not limited to the table system or the matrix system as shown in FIG. 8, but is stored in another data structure. You may let them.

  The wire harness circuit check work support system can be configured as a circuit check work support server instead of the stand-alone configuration as shown in FIG. In this case, the PC of FIG. 2 is provided with an appropriate network interface as a server, the check specification is input from another PC (client PC) connected thereto (S102), and the result is output to the client PC ( S105).

  In the above embodiment, first, all procedures of the circuit check work are determined using the wire harness circuit check work support system 51, and then the circuit check work is performed according to the procedure. However, the present invention is not limited to this, and the procedure of the next operation using the system 51 may be determined in parallel while actually performing the circuit check operation.

  How to divide the target wire harness and the number of specifications of each part can be arbitrarily determined. The wire harness circuit check work support system 51 is not limited to a wire harness for automobiles, but can be used for a circuit check work for a wire harness such as an electric product.

  It goes without saying that the system may be simplified by using the same mark to be recorded in the circuit operation check record information when it is actually checked and when it is substantially checked.
