Description

  The present invention relates to presentation of a connection situation in which a plurality of electrical components are connected by wiring.

  For example, in a vehicle, the system is complicated in order to improve engine control and brake control. In the brake control, an ABS that avoids brake lock and improves braking performance is introduced, and this ABS system includes a plurality of electrical components such as a brake actuator and a speed sensor for each wheel. There are various types of engine control, such as an exhaust gas circulation system, an anti-knocking system, and an idle speed control system.

  In each of these systems, the number of electrical components tends to be more complicated and the number of electrical components tends to increase in order to improve the system functions, and the number of wirings used to connect electrical components is also increasing. Further, when wiring, avoiding vehicle components (for example, engine, radiator, etc.), wiring is performed up to electrical components to be connected.

  During maintenance and inspection of each system, it is necessary to check the wiring status between the electrical components. In this case, the system design circuit is a circuit using wiring and various connectors for connecting this wiring to the electrical components. The rewritten version is used. However, as described above, due to the complexity of the system and the increase in the number of electrical components, this rewritten circuit diagram is naturally complicated, and the circuit diagram is also a booklet that covers several pages for one system. . For this reason, when measuring the state of signal transmission between electrical components, look for the connector connected to the electrical component in the circuit diagram booklet and find out about the electrical component connected to the electrical component. It was necessary to identify the connector each time while referring to the booklet. Such work required sufficient attention and was complicated. In particular, the connection between one electrical component and another electrical component may be shown over a circuit diagram of several pages, which is more complicated. The vehicle has been described as an example, but the same applies to a ship, an aircraft, a machine tool, a factory facility, or the like.

  In view of such a situation, a technique for simply presenting a connection situation has been proposed (for example, Patent Document 1).

JP 2002-315124 A

  In this patent document, if the connection part for which the wiring state is to be checked is specified, the connection state between the electrical components can be grasped by displaying the schematic shape of the part including the connection part, but the connection state is displayed as a circuit diagram. In this case, the connection status is merely displayed, and the consideration of the circuit diagram display is not sufficient.

  The present invention has been made to solve the above-described problems in presenting the connection status between electrical components, and an object of the present invention is to provide a method for easily grasping the connection status between electrical components in a circuit diagram.

In order to solve at least a part of the problem, the connection status presentation device of the present invention is:
A device for presenting a connection situation in which a plurality of electrical components are connected by wiring,
When a display target that is a display target of the connection status is specified, a specifying unit that specifies an electrical component corresponding to the specified display target and a wiring that connects the electrical component,
A connection diagram creation unit for creating a connection diagram drawing data of a drawing image for drawing a connection diagram obtained by connecting the electrical component image of the specified electrical component with the wiring locus image of the specified wiring on the xy plane;
In the connection diagram, paying attention to an adjacent wiring trajectory image extending in one axial direction of the xy plane and another wiring trajectory image, an area between the focused wiring trajectory images is defined as the focused wiring trajectory. An inter-wiring margin area defining portion that defines an inter-wiring margin area that can be deleted when the image and the other wiring locus image are drawn close to each other along the other axial direction of the xy plane;
A data processing unit for subjecting the created connection diagram drawing data to a data processing process for deleting data in a range that the defined inter-wire margin area occupies along the other axial direction;
A connection diagram in which the electrical component image is connected with the wiring locus image in a state where the inter-wiring margin area is deleted and excluded along the other axial direction based on the connection diagram drawing data after the data processing. And a connection diagram drawing unit for drawing.

  In the connection status presentation device of the present invention configured as described above, when a display target to be displayed as a connection status is specified by a user or the like, an electrical component and a wiring corresponding to the specified display target are specified. Then, in order to display the state where the specified electrical component is connected by wiring, first, a connection diagram in which the electrical component image of the specified electrical component is connected by the wiring trace image of the specified wiring is drawn on the xy plane. Connection diagram drawing data of a drawing image is created.

  In this case, connection diagram drawing data is created by using a method based on circuit diagram data on the xy plane including the specified electrical component / wiring and other electrical components / wiring, and an electrical component for the identified electrical component / wiring. We decided to take a method based on product drawing data and wiring trace data. In the former technique, circuit diagram data is drawn by arranging and drawing the electrical component image of each electrical component and the wiring locus image of each wiring connecting the electrical component on the xy plane, and this stored circuit diagram Connection diagram drawing data is created based on the circuit diagram data read from the data storage unit. Since the circuit diagram data is drawn by placing the specified electrical component / wiring and other electrical components / wiring on the xy plane for the electrical component image / wiring locus image, the identified electrical component / wiring By deleting the electrical component image / wiring trace image for the other electrical components / wiring, the wiring diagram drawing data of the wiring diagram in which the electrical component image of the identified electrical component is connected by the wiring trace image of the identified wiring is created. be able to.

  The latter method includes electrical component drawing data for each electrical component for rendering the electrical component image on the xy plane, and wiring trace rendering for each wiring for rendering the wiring locus image on the xy plane. And reading the electrical component drawing data and the wiring locus drawing data for the specified electrical component / wiring from the stored data, and reading the electrical component drawing data and the wiring The connection diagram drawing data is created based on the locus drawing data.

  And, since the connection diagram by the connection diagram drawing data is for drawing the electrical component image of the electrical component and the wiring trace image of the wiring connecting the electrical component for the specified electrical component / wiring, the following The display is simplified as follows. First, in the connection diagram, attention is paid to an adjacent wiring locus image extending in one axial direction of the xy plane and another wiring locus image, and an area between the noted wiring locus images is defined as an inter-wiring margin area. To do. This inter-wiring margin area can be deleted when the noted wiring trajectory image and the other wiring trajectory image are drawn close to each other along the other axial direction of the xy plane. If the blank area is deleted and excluded, the noticed wiring locus image and the other wiring locus image can be drawn close to each other along the other axial direction of the xy plane. Therefore, the created connection diagram drawing data has been created through a data processing process for deleting data in a range occupied by the defined inter-wire margin area along the other axis direction. To the new drawing data in which the data in the range occupied by the inter-wiring margin area along the other axial direction is deleted. That is, drawing data for drawing the electrical equipment and wiring in a state where the inter-wiring margin area is excluded can be obtained.

  Therefore, the connection diagram drawn based on the new drawing data obtained in this way (that is, the connection diagram drawing data after the data processing) has been excluded by removing the inter-wiring margin area along the other axial direction. In this connection diagram, the wiring trace image of interest and the other wiring trace image are brought close to each other along the other axial direction of the xy planar circuit diagram. It will be drawn. Then, an output unit is provided so that the drawn connection diagram is output to, for example, a display device or a printing device. Therefore, according to the connection status presentation device of the present invention, it is possible to draw and present a connection diagram in which only the electrical components corresponding to the display target of the connection status are connected by wiring in a state where the wiring trajectory images are close to each other. It is possible to present a simple connection diagram without an extra portion of wiring and electrical components, and it is possible to easily grasp a connection state between electrical components in a circuit diagram by this connection diagram.

  The connection status presentation according to the present invention may be as follows. For example, in the created connection diagram, if there is no other wiring trajectory image extending in the one axial direction in the region along the other axial direction from the focused wiring trajectory image, the focused wiring trajectory An area along the other axial direction side is defined as a wiring side margin area that can be deleted from the image, and the wiring side margin area is also excluded and drawn. For this reason, in the data processing of the connection diagram drawing data that has been read and created, data is also deleted for the range occupied by the specified wiring side margin area along the other axis direction, and the connection diagram drawing is performed. In this case, in addition to the state in which the inter-wiring margin area is deleted along the other axial direction, the electrical component image is removed in a state in which the wiring side margin area is deleted and excluded along the other axial direction. A connection diagram connected with the wiring locus image is drawn. In this way, since a simpler connection diagram can be presented, it is easier to grasp the connection status between the electrical components.

  Further, the connection diagram drawing unit determines whether or not there is interference of the electrical component image of the specified electrical component when drawing the connection diagram. If there is no interference of the electrical component image, the electrical component image is arranged. It can be drawn. In this way, since the electrical component image can be drawn in close proximity, the connection status between the electrical components can be more easily grasped through further simplification of the connection diagram.

  Further, the connection diagram drawing unit determines whether or not there is room for simplification of the locus of the wiring locus image connecting the electrical component image of the specified electrical component when drawing the connection diagram, and the wiring locus image If there is room for simplification, the wiring locus image can be simplified and drawn. In this way, the wiring trace image between the electrical component images can be drawn in a simple form such as a linear trajectory, so that the connection diagram can be further simplified and the connection status between the electrical components can be more easily grasped.

  Next, an embodiment of presenting a connection situation according to the present invention will be described based on examples. FIG. 1 is a block diagram showing a schematic configuration of a connection display system 10 according to an embodiment in which the present invention is applied to an apparatus for displaying a connection state between electrical components of a vehicle. FIG. 2 is a conceptual diagram using the connection display system 10. It is.

  As shown in the figure, the connection display system 10 includes a display 12 as a display device composed of a liquid crystal screen or the like, a keyboard 14 as an input / output device, and a mouse 16. The connection display system 10 also includes a hard disk drive (hereinafter referred to as HDD) 18 for storing data and a CD drive 22 for reading the contents of the CD-ROM 20, and a CPU 24 as a central processing unit that performs overall control thereof. Are connected to the above-mentioned devices, the RAM 26 and the ROM 28 by a bus. Since the connection display system 10 has such a configuration, in this embodiment, the connection display system 10 is configured by a computer alone, and is installed on a gantry (not shown) so as to be movable around the inspection vehicle. As shown in the figure, the computer 11 can be connected to the server 30 via a network (for example, the Internet), and the computer 11 and the server 30 can constitute a connection display system. A network control circuit 39 is added. A connection display system using the server 30 will be described later.

  The CPU 24 executes a connection status display program, which will be described later, stored in the HDD 18. At this time, the CPU 24 reads data from the HDD 18 and the CD drive 22, temporarily writes data to and reads data from the RAM 26, and controls the display 12. Etc. The CD-ROM 20 stores in advance a connection status program to be transferred to the HDD 18 and various data to be described later, and these program data are transferred to the HDD 18 via the CD drive 22. The connection status program and data are transferred from various portable recording media (portable recording media) such as an IC card in addition to a floppy disc and a magneto-optical disc in place of those stored in the CD-ROM 20. It can also be configured. Further, the computer 11 has a network control circuit 39, and the connection status program and data are transferred from an external server via the network control circuit 39 and a network (for example, the Internet, an intranet, etc.) to which the computer 11 is connected. It can also be configured. Such a transfer from the server is performed prior to the execution of the processing every time the connection status display is executed, or only when the connection status display is performed for the first time, and the program and data are stored in the HDD 18 at the time of the transfer. You can also

  Next, data in the connection display system 10 will be described. In the present embodiment, a wiring diagram is drawn by using part drawing data for each part to be drawn by arranging the electrical components (parts) on the xy plane, and wiring trace drawing data for each wiring of the wiring trace of the wiring connecting the electrical components. There is a feature in the point to create. 3 is an explanatory diagram for explaining the connection data used in the connection display system 10, FIG. 4 is an explanatory diagram for explaining connector drawing data included in the connection data, and FIG. 5 is a drawing using parts and wiring drawing data. FIG. 6 is an explanatory diagram showing a part of the system circuit diagram that can be created and displayed, and FIG. 6 is an explanatory diagram showing a continuation of the system circuit diagram shown in FIG.

  As shown in FIG. 3, the connection data includes data on the connector and data on electrical components (parts) and wirings to be connected to the connector. This is in preparation for specifying parts / wirings to be displayed via a connector as will be described later. The electrical components (parts) to be connected to the connector include various actuators and their control devices, for example, engine-related injectors, knocking sensors, engine speed sensors, etc. There are electronic control devices (ECU, control module, etc.) to be controlled.

  As shown in FIG. 4, the connector-related data includes image data for drawing the end face shape of each connector and pin numbers included in the connector, component list data for each connector, position information data for pin numbers, and wiring. Contains information data.

  The connector image data is image data for drawing the connector appearance (outline) and pin number on the display 12 as shown in FIG. As shown in the figure, the image data is stored for each connector by associating code number data for specifying the connector with color data for specifying the color of the connector.

  The component list data is data indicating which electrical component each connector is attached to, and is used as a key for a later-described search. For example, a connector (see FIG. 4) specified by code number data I8 is used for the injector of the third cylinder of a 6-cylinder engine, and this connector is given the name of injector # 3. Is a parts list name. The parts list data is constructed by associating the part list name (injector # 3) with the code number data (I8) of the connector.

  The position information data of the pin number is data for specifying the position of the pin possessed by the connector, for example, the position of the pin 1 and the pin 2 (in this case, the left and right positions) in the case of an I8 connector. The connection information data specifies information about each pin of the connector and the wiring connected to the pin (for example, the number and color data for distinguishing the wiring), the pin number of the connection destination via this wiring, and the connector having this pin. This is data in which the above-mentioned code number data for matching is associated with the parts list name of the connector. In this case, since the connector can be specified by the code number data and the parts list name (for example, the above-mentioned injector # 3), the data storage of either the code number data or the parts list name is performed when the connection information data is constructed. It can also be.

  Data on parts / wiring is prepared for each system such as engine control system, ABS system, light control system, indoor lighting system, etc. included in the vehicle. Actuators / sensors / electronic control devices for each system, etc. It is constructed based on the design circuit. The parts / wiring data includes parts / wiring image data, system list data, parts / wiring drawing shape / trajectory information data, and position information data. The image data of the parts is image data for drawing each part included in the system, for example, in a block diagram schematically in an xy plane circuit diagram, and also schematically represents the function performed by each part. This data is necessary for drawing the part in the circuit diagram. The wiring image data is data for drawing each wiring connecting the parts included in the system as a locus of a straight line or a bent straight line in an xy planar circuit diagram.

  The system list data is data indicating the title of the system, and distinguishes between a series of connection systems including parts wired and connected in the system, for example, in-vehicle communication system, front wheel brake sensor system, air conditioning system, etc. And data (for example, part names and symbols, wiring symbols, etc.) for distinguishing between parts and wirings included in each connection system. That is, based on the system title and the connection system in the system, the parts and wirings included in the connection system can be specified. It is also possible to identify all parts and wiring included in the system.

  The drawing shape / trajectory data of parts / wiring is data necessary for defining the drawing shape of the parts and the wiring trajectory in the image data described above. The part / wiring position data is data necessary for defining the drawing position such as where the part image based on the image data described above is to be placed and drawn in the xy plane circuit diagram. This is data necessary for drawing position definition when drawing while connecting parts in the figure. By using such data, an image of each part is drawn on an xy plane circuit diagram, and each wiring is drawn as an image of its wiring locus. In this case, the drawing trajectory data and the drawing position data for the wiring include data for drawing these places together with the wiring for drawing of branching / joining points in wiring mounting. Also draws branching / joining points.

  The above-described data about parts / wiring is associated with information (for example, part name, part symbol, wiring code, etc.) for distinguishing parts and wiring. Therefore, when a part is specified or a wiring is specified as will be described later, the specified part / wiring can be drawn as described above using the image data or the like.

  For example, the engine control system is configured to include all of the above-described data regarding parts such as an injector, a power source, a fuse box, and an ignition switch, and wirings connecting these parts. Therefore, if a part / wiring to be displayed is specified as will be described later, a connection diagram including the specified part / wiring can be drawn using the data regarding the specified part / wiring. Moreover, if all the data on the parts (electrical components) and the data on the wiring are used, connection diagrams (circuit diagrams) of the engine control system as shown in FIGS. 5 and 6 can be displayed. In this engine control system circuit diagram, the injector # 3 to which the connector indicated by I8 is attached has one terminal connected to the power supply, the fuse box, and the ignition switch, and the other terminal connected to the engine control module. It shows that it is connected to the 30th pin. In this case, it is also shown that the 30th pin corresponds to the pin 1 of the connector specified by E15. Further, in order to cut out and display a circuit portion including such a connected device, the connector data also includes position information of a connector serving as a tag for reading out the circuit portion.

  Connection diagram of the engine control system as shown in FIG. 5 and FIG. 6 using the above-mentioned data regarding all parts / wiring included in the system and the wiring diagram including the specified parts / wiring to be displayed ( The circuit diagram) can be created on the display 12 and displayed on the display 12, and the circuit diagram can be generated as an image without displaying on the display. By the way, when displaying the entire connection diagram including the specified parts and wiring and the system connection diagram (circuit diagram) on the display 12, the size of the circuit diagram greatly exceeds the display size of the display, so scroll display A display method such as In such a scroll display, since a scroll operation and display are necessary for grasping the connection state, it becomes complicated. In this embodiment, a specific connection state presentation process is performed. Details thereof will be described later.

  Each of the above-mentioned data differs depending on the grade, option, engine type, etc. of the vehicle. Therefore, for each vehicle to be inspected, the CD-ROM 20 in which data is read from the CD-ROM 20 or recorded for each vehicle is stored. Use replacement. Alternatively, as will be described later, such data can be prepared in the server and read as needed, or only the result can be received from the server.

  Next, connection display processing performed by the connection display system 10 of the present embodiment will be described. FIG. 7 is a functional block diagram of connection diagram creation / display processing constructed by the connection display system 10, and FIG. 8 is a flowchart showing connection search / display processing.

  As shown in these drawings, the connection display system 10 includes a drawing data storage unit 41, a display target designating unit 42, an electrical component / wiring specifying unit 43, using a computer 11 constituting the computer 11 using a CPU 24, a RAM 26, and the like. The connection diagram image creating unit 44, the margin area defining / data processing unit 45, and the connection diagram drawing / display output unit 46 are configured. The drawing data storage unit 41 includes electrical component drawing data for each electrical component for rendering each electrical component in the xy planar circuit diagram, and wiring for each wiring for rendering the wiring as a wiring locus in the xy planar circuit diagram. The drawing data storage unit 41 stores the locus drawing data, and the storage device for the data shown in FIG. The display target designating unit 42 performs a function for designating a display target to be displayed as a connection status display, and the touch switch of the display 12 corresponds to the display target designating unit 42 in addition to the keyboard 14 and the mouse 16. . The electrical component / wiring identifying unit 43 identifies electrical components and wirings corresponding to the display target specified by the display target designating unit 42, and the connection diagram image creating unit 44 draws data about the identified electrical components and wirings. Is created, and an image of the connection diagram is created by connecting the electrical component image with the wiring locus image based on the drawing data. The margin area defining / data processing unit 45 applies the drawing data to the data processing so as to exclude between the wiring locus images and the left and right margin areas of the wiring from the connection diagram in the image of the connection diagram. The display output unit 46 draws a connection diagram in a state where the blank area is deleted and excluded based on the new drawing data subjected to the data processing, and outputs the connection diagram to the display 12 or a printer (not shown).

  As shown in FIG. 8, first, the user (maintenance inspector) waits for designation of the display target of the connection state (step S100). FIG. 9 is an explanatory diagram for explaining the state of the standby screen for designating the display target. As shown in FIG. 9, a plurality of methods are prepared for designating the display target. The first technique is a technique that uses a part included in a connection diagram desired to be displayed as a clue. The second method is a method of designating both parts to be connected to wiring in a connection diagram desired to be displayed, and the third method is a series of connection systems including parts connected by wiring, for example, This is a method for designating an in-vehicle communication system, a front wheel brake sensor system, an air conditioning system, and the like.

  When the connection search / display processing routine of FIG. 8 is executed, the connection display system 10 first displays a screen that prompts the display target designation by the first method described above. FIG. 10 is an explanatory diagram showing the state of the part designation method when the connection search / display processing routine is executed. It is assumed that the user selects a designated method from the parts shown in FIG. 9 and selects a speed sensor as the part. In this case, the part name can be input, and the connection display system 10 can display a list of parts in order to simplify the part selection by the user. For example, the classification of parts such as sensors, actuators, and control devices is displayed as a list, and the user selects a part from the classification list. In addition, since the part is connected to the corresponding connector, the part corresponding to the connector can be selected by selecting the connector. In this case, the connector may be displayed in a drawing image as shown in FIG. 4 or a list of connector names.

  When the user selects a part, the connection display system 10 displays the type of the speed sensor on the left side of the screen as shown in FIG. 10, and on the right side of the screen is the speed sensor (on the right side of the front wheel) that is the topmost speed sensor. Display the entire connection diagram including Speed Sensor (Front LH). This connection diagram is created using the above-described data for all the parts and wirings constituting a series of connection systems (in this case, the front wheel brake sensor system) including the speed sensor on the right side of the front wheel. In FIG. 10, the entire connection diagram is displayed because there are few parts related to the speed sensor. However, as described in FIGS. 5 and 6, when there are many parts, a part of the entire diagram is displayed. The display location is a circuit diagram portion around the speed sensor.

  While viewing this FIG. 10 on the display 12, the user selects a part to be displayed, in this case, the front wheel speed sensor. Then, the connection display system 10 waits for a user designation of a display range including this part. In this embodiment, as shown in FIG. 9, the range of the connection diagram including the designated part can be selected. FIG. 11 is an explanatory diagram for explaining a connection diagram when the connection diagram range of the selected part is up to the first connection item, and FIG. 12 is a connection diagram when the connection diagram range of the selected part is up to the connection target part. FIG. 13 is an explanatory diagram for explaining the connection diagram in the case where the connection diagram range of the selected part is up to the range including the power supply / ground. As shown in FIG. 9, the connection diagram range can be selected in parallel with the part specification as shown in FIG.

  When the user selects a method to be specified from the connection target parts shown in the middle part of FIG. 9, the connection display system 10 displays an input screen of both the connection target parts on the display 12. As a display method, it is possible to simplify the designation of parts by displaying a list of a part and its connected parts. As described above, it can be configured to directly input the part name. In addition, when the user selects a method specified from the connection system shown in the lower part of FIG. 9, the connection display system 10 displays a list of connection systems on the display 12 to prompt input, or directly inputs the connection system. Can be configured. As another display target designation, it is also possible to take a technique of coding an operation failure (failure) and displaying connection of parts and wiring related to the failure code. In this case, the parts and wiring related to the operation are stored in advance in association with the operation failure code, and the part and the wiring are specified by specifying the failure code.

  When a display target is designated by any of the above-described methods, the connection display system 10 identifies parts and wirings corresponding to the designated display target (step S110). In specifying the parts / wiring, various data on the connector and the parts / wiring described in FIG. 3 are used. Following the specification of the parts / wiring, the connection display system 10 simply uses the previously described image data, shape / trajectory data, drawing position data (hereinafter referred to as these data) necessary for drawing the specified part and wiring (wiring locus). (Referred to as drawing data) is read (step S120), and on the basis of the read drawing data, the identified part and wiring are connected as a drawing image corresponding to the shape, trajectory and position defined by these data. Is created on the xy plane (step S130). Thus, what is created in step S130 is an image of the connection diagram, not the connection diagram itself. This is due to the following reason.

  Eventually, the connection diagram is displayed or printed out as will be described later. In this embodiment, the image data is processed in the processing after step S130, and the connection diagram is created using the processed data. To do. Therefore, before this data processing, it is not necessary to display the identified parts / wiring as a connection diagram drawn by the above-mentioned data, and it is only necessary to obtain an image to be subjected to data processing. Needless to say, a connection diagram can be created and displayed even before data processing.

  FIG. 14 is an explanatory diagram for explaining the state of the connection diagram image of the identified parts P1 and P2 and the wirings L1 and L2 between them. In this case, both the parts P1 and P2 are specified as display objects, and the wirings L1 and L2 are also specified as display objects. In the connection diagram image shown in FIG. 14, the parts P1 and P2 are drawn in the shape and drawing position based on the respective drawing data, and the wiring L1 and the wiring L2 also have the branch points BK depending on the respective drawing data. It is drawn with a wiring trace that includes the schematic diagram.

  Following the creation of the connection diagram image shown in FIG. 14, the connection display system 10 defines a blank area that is unnecessary when presenting the final connection diagram from the above connection diagram image (step S <b> 140). In this embodiment, the blank area is defined from the state of drawing the wiring in the connection diagram image. Referring to FIG. 14, attention is paid to adjacent wiring drawing portions extending in the y-axis direction (vertical direction) in the connection diagram image on the xy plane. In FIG. 14, this portion of interest is the wires of interest LB1 to LB4 in the drawing. Since the connection diagram image of FIG. 14 extends in the x-axis direction, the wiring drawn in the x-axis direction is in a state of close proximity, so that there is room for close display as described later. Absent. Therefore, attention is paid to the wiring extending in the y-axis direction as described above.

  FIG. 15 is an explanatory diagram for explaining how the margin area is defined. As shown in FIG. 15, the connection display system 10 checks the connection diagram image to see whether there is a space between the wires among the wires of interest LB1 to LB4. That is, if there is a margin between adjacent wirings, there is a room in which the adjacent wiring can be drawn without the margins, and this margin is defined as an inter-wiring margin area HJ. In FIG. 15, an inter-wiring margin area HJ1 between the adjacent wirings LB1 and LB2 and an inter-wiring blank area HJ2 between the adjacent wirings LB2 and LB3 are shown.

  In defining the inter-wiring margin area HJ, the following points are taken into consideration. First, the wirings LB3 to LB5 in the drawing are already drawn close to each other in the connection diagram image. In the drawing position data, the drawing interval between these wires (the minimum drawing interval) is determined, and the wires LB3 to LB5 are drawn at this drawing interval. Now, paying attention to the wiring LB2 and the wiring LB3, the interval between the two wirings is wider than the above-described drawing interval, so that the wiring LB2 and the wiring LB3 are equal to the above drawing minimum interval or n times (n In the case of drawing at an interval of a natural number of about 2 to 5, the inter-wiring margin area HJ2 is defined as a margin that can be deleted. For the inter-wiring margin area HJ1, in addition to the above-described minimum drawing interval, interference with the part P1 was also considered. That is, the part P1 is not necessarily drawn by being deleted in the size or the number of terminals, so the area that does not interfere with the part P1 is defined as the inter-wiring margin area HJ1. Depending on the part shape and the number of terminals, an area interfering with the part can be set as an inter-wiring margin area HJ as described later.

  Further, in the connection display system 10, in addition to the definition of the inter-wiring margin area HJ between the wirings described above, the wiring side area, in this embodiment, the connection diagram image extends in the x-axis direction of the xy plane. Therefore, the margin of the wiring side area in the x-axis direction is also defined as a margin area that can be deleted. That is, as shown in FIG. 15, the right side area of the wiring LB5 has no drawing corresponding to the specified wiring, so this area is defined as a wiring side margin area HSJ1. In FIG. 15, since there is no margin on the left side of the wiring LB1 on the left side, the wiring side margin area HSJ1 is not defined for the wiring LB1.

  Following the definition of the margin area, the connection display system 10 processes the drawing data of the parts P1 and P2 and the wirings L1 and L2 based on the above-described inter-wiring margin areas HJ1 to HJ2 and the wiring side margin area HSJ1 (step S150) A connection diagram is created based on the obtained processed drawing data (step S160). FIG. 16 is an explanatory view showing a state of data processing of drawing data based on the margin area and a state of creating a connection diagram based on the obtained drawing data after processing.

  As shown in FIG. 16, first, data in a range occupied by the inter-wiring margin regions HJ1 to HJ2 along the x-axis direction (hereinafter, margin x-axis data) is deleted. In FIG. 16, since the part P2 interferes with the margin x-axis data of each margin area, data corresponding to the margin x-axis data is deleted from the drawing data of the part P2. The same applies to the wiring side margin area HSJ1 shown in FIG. 15, and data corresponding to the margin x-axis data of the wiring side margin area HSJ1 is deleted from the drawing data of the part P2. Then, the part P2 becomes a part P2A and a part P2B shown in the figure, and a new drawing for drawing each of these parts is obtained.

  As for the wirings L1 and L2, new drawing data for drawing the wiring is obtained by reducing the length corresponding to the blank x-axis data while leaving the branch point BK included in the wiring trajectory. Then, the connection display system 10 creates a connection diagram of the parts P1 and P2 and the wirings L1 and L2 based on the new drawing data thus obtained (step S160). FIG. 17 is an explanatory diagram showing a connection diagram created with new drawing data obtained by deleting the margin x-axis data for the margin area. As shown in FIG. 17, in the created connection diagram, the parts P1 and P2 are connected by the wirings L1 and L2 in a state where the inter-wiring margin areas HJ1 to HJ2 and the wiring side margin area HSJ1 are deleted and excluded. . In this case, since the parts P2A and P2B have the same size in the height direction in the drawing of the original part P2, the parts P2A and the parts P2B are drawn in a state of being combined by deleting the inter-wiring margin area HJ2. In this case, it is also possible to process the connection diagram as it is without creating a connection diagram in step S160.

  Next, the connection display system 10 determines whether there is room for further simplification in the connection diagram drawing (step S170). The room for simplification includes the presence / absence of interference between parts in the connection diagram created in step S160, simplification of part shape, simplification of wiring locus, and the like. For example, if there is no interference between parts, there is room for simplification to bring parts closer together. Further, if the wiring locus is bent, there is room for simplification so that the wiring is a straight locus. Furthermore, if it is possible to change the length of the wiring along the axis other than the x-axis focused on when the margin area is deleted, specifically, the y-axis direction, the simplification such as shortening the length is possible. There is room. The simplification of the part shape is similar, and if there is a part that does not have a terminal in the drawn part, there is room for simplification by deleting the part and shortening the length of the part. If it is determined that there is no room for simplification of drawing, the connection display system 10 proceeds to step S200 described later, outputs the connection diagram to the display 12 or a printer (not shown), and ends this routine.

  On the other hand, if there is room for simplification as described above, the drawing data / drawing position data is processed again in accordance with the simplification to change the drawing position of parts or wiring or prepare for wiring simplification (step S180). FIG. 18 is an explanatory diagram showing a connection diagram simplification. As shown in the figure, in the connection diagram created in step S160, there is no interference between the parts P1 and P1, and the wiring L2 has a bending locus, so that the data for moving the part P2 below the part P1 is reproduced. Processing and reprocessing of the data for setting the wiring L2 as a linear locus are performed (FIG. 18A), and a connection diagram is created based on the redrawed drawing data (step S190: FIG. 18B). )). Then, this connection diagram is output to the display 12 or a printer (not shown) (step S200), and this routine is terminated.

  Next, the state of the connection search / display process when a connection system is designated as a display target will be described. FIG. 19 is an explanatory diagram showing how a connection diagram is created when, for example, a communication system in a vehicle is designated as a display target. In specifying a connection system as a display target, the user selects a specified method from the connection systems shown in FIG. 9 and specifies a connection system called a communication system. In this case, the name of the connection system can be input, and the connection display system 10 can display a list of connection systems in order to simplify the selection of the connection system by the user. For example, a list of in-vehicle communication systems, front wheel brake sensor systems, air conditioning systems, etc. is displayed, and the user designates a connection system desired to be displayed from the list.

  The upper part of FIG. 19 shows a circuit diagram of the entire system including a communication system designated as a display target. This circuit diagram extends in the x-axis direction, and when displaying on the display 12, a scroll display method is used. And since the circuit diagram of the communication system shown in the figure is dotted with parts constituting this, even when the circuit diagram part of the communication system is displayed, it cannot be displayed on one screen, and the scroll display method is used. . The diagram shown in the middle of FIG. 19 shows the above drawing data of parts and wiring corresponding to the communication system, that is, the parts and wiring included in the circuit diagram of the communication system, when the communication system is designated by the user as a display target. (Step S120), and a connection diagram image created based on the data is shown (step S130). In this case, the parts and wirings included in the connection system (for example, communication system) specified by the user as the display target are identified by the part name, symbol, and wiring that distinguish the parts and wiring included in each system for each connection system. The system list data in which data such as the symbol is stored is referred to, and is compared with the connection system of the list data and the connector specified by the user.

  Then, as shown in the middle diagram, the inter-wiring margin areas HJ1 to HJ3 and the wiring side margin areas HSJ1 to HSJ2 between the wirings extending in the y-axis direction are defined (step S140). Data processing is performed such that the blank area is deleted and excluded (step S150), and a connection diagram is created (step S160). In this example, the drawing length of the part P1 shown in the drawing has a margin after the blank area is removed, and the margin portion YP in the drawing has room for simplification when drawing the part P1. (Step S170 affirmative determination). Therefore, the margin part YP is reprocessed so as to delete data (step S180), and a connection diagram is created and displayed based on the obtained drawing data (steps S190 to S200).

  As described above, in the connection display system 10 of the present embodiment, when a connection diagram is created and displayed so as to assist the maintenance / inspection work, the operator (user) only specifies the display target. This user can easily recognize the connection diagram by displaying a connection diagram in which parts corresponding to the display target are connected by wiring. In addition, this connection diagram does not include parts and wiring other than the display target, and draws a connection diagram in which only the parts corresponding to the display target of the connection status are connected with the wiring trace images close to each other. Can be presented. As a result, according to the connection display system 10 of the present embodiment, a simple connection diagram without extra wiring and parts can be presented, and the connection state between the parts can be easily grasped in a circuit diagram by this connection diagram. . For this reason, it is possible to simplify the work such as maintenance and inspection using the circuit diagram and improve the efficiency.

  Moreover, in the final connection diagram, the wiring side margin area HSJ1 on the right side of a certain wiring (wiring LB5 in FIG. 15) is also deleted and excluded, so that the wiring diagram is more compact. Thus, the connection diagram can be further simplified and the connection state can be easily grasped.

  Further, when there is no part interference or when it is possible to simplify the wiring trajectory image, the connection diagram can be further simplified and the connection state can be further simplified by proximity arrangement or straight line drawing (steps S180 to S190). It is also easy to grasp.

  In addition, when specifying the display target, various display methods such as display target specification from the parts, display target specification from the connection system, display target specification from the error code were adopted, so the versatility of the connection diagram display Is preferable.

  In addition, since drawing data for parts and wiring corresponding to the designated display target is read, it is possible to reduce the calculation load and reading time associated with reading the data. In the present embodiment, the drawing data for the parts and wiring corresponding to the designated display object is read. However, if the processing capacity of the CPU 24 of the connection display system 10 has a margin, it is not the designated display object. You can also read data about parts and wiring and create a connection diagram image based on this data. Specifically, as shown in the upper part of FIG. 19, in addition to the parts and wiring corresponding to the communication system designated as the display target, the data is also read for parts and wiring other than the communication system, and these parts and wiring are read. In the connection diagram image including the line margin area HJ and the wiring side margin area HSJ, the data processing associated therewith may be performed.

  In the above-described embodiment, a simplified connection diagram as shown in FIG. 18B is finally shown, but this connection diagram display is used for any display intention of the user, for example, a failure that has occurred. Various parts / wiring indications involved, parts / wiring indications for recovery / cause analysis of the failure, and parts / wiring indications desired to be inspected. On the other hand, on the connection display system 10 side, data on parts and wirings included in the finally created connection diagram, such as part names and wiring types, are collected for each connection diagram with reference to the connection data in FIG. Then, a simplified connection diagram database can be newly constructed using the frequency of creating the simplified connection diagram, the parts / wiring list for each connection diagram, and the like. Therefore, the data in these databases can be used for failure analysis, and if the user's display target specification matches the simplified connection diagram in the past, for example, the specific part can be identified as a part included in the past connection diagram. If they match, the simplified connection diagram can be read from the database and displayed.

  Next, another embodiment will be described. This embodiment is different from the above embodiment in which drawing data for each part / wiring is provided, whereas a connection diagram is created using drawing data for drawing a system circuit diagram as a circuit diagram on the xy plane. There are features. That is, a connection diagram of parts / wirings to be displayed is created from a circuit diagram of the entire system. FIG. 20 is an explanatory diagram for explaining a data configuration in the connection display system 10 in another embodiment.

  As shown in FIG. 20, in this embodiment, image data for rendering the system circuit diagram itself as shown in the upper part of FIG. 5, 6 or 19 as a circuit diagram on the xy plane is provided for each system. . The circuit diagram for each system drawn based on this image data is a connection diagram in which all the parts included in the system are drawn in a predetermined part shape, and each part is connected with the wiring of each wiring locus. The connection diagram is handled in the same manner as the connection diagram image that is the target of the blank area definition in the embodiment described above. The image data for each system is handled in the same manner as the drawing data that is the target of the data processing for blank deletion / simplification in the embodiment described above.

  In addition to such image data of the system circuit diagram, this embodiment includes data for defining the relationship between the wiring and the parts to be connected, the relationship between the failure and the part that can cause the failure, and the like. In other words, this embodiment includes system list data, parts / wiring connection information data, and failure joint information data. As in the previous embodiment, the system list data is data indicating the title of the system, and a series of connection systems including parts wired and connected in the system, for example, in-vehicle communication system, front wheel brake sensor Data for distinguishing systems, air conditioning systems, etc., and data for distinguishing parts / wirings included in each of these connection systems (for example, part names and symbols, wiring symbols, etc.) are provided. That is, based on the system title and the connection system in the system, the parts and wirings included in the connection system can be specified.

  The connection information data of parts / wiring includes, for each wiring, data that associates the parts to be connected at both ends with the connection location (connection terminal) in the part, the branching / coupling of wiring, or the bending location of the wiring trajectory, etc. This includes data on the wiring trajectory. Such connection terminals and wiring trajectory data of the connection target parts are used in the above-described margin location definition. For example, when the wiring side margin area HSJ1 is defined as described with reference to FIG. 15, the margin area is defined so that the connection terminals of the part P2 and the wiring LB5 are not included in the wiring side margin area HSJ1. When the inter-wiring margin area HJ2 is defined, the margin area is defined so that the branch point BK of the wiring LB3 is not included in the inter-wiring margin area HJ2.

  As described in the previous embodiment, the defect solidarity information data is data in which a coded operation failure (defect) is associated with a part or wiring related to the defect code. It can be used to identify parts and wiring that can cause the failure. When a part and a wiring that may cause a failure are specified, wiring connection terminal data for the part and wiring trace data described above can be specified from the connection information data of the part / wiring.

  Even in this embodiment for storing the image data of the system circuit diagram, the processing for presenting the connection status is not different from the embodiment described above, and the target of the margin definition is the system circuit diagram (connection diagram). The object of data processing is merely image data for drawing a system circuit diagram. Based on these points, application of the processing shown in FIG. 8 will be described.

  First, in steps S100 to S110 shown in FIG. 8, the part / wiring is specified while waiting for the designation of the display target as described above. As described with reference to FIG. 9, the display target designation standby includes a method of using parts as a clue, a method of specifying both parts to be connected to wiring, and a method of specifying a connection system. In this case, in this embodiment, since it has the above-described defect joint information data, it is also possible to specify parts and wiring from the malfunction (defect).

  When the part / wiring is specified in this way, in the subsequent step S120, image data of the system circuit diagram of the system including the part / wiring is read. This data reading can be achieved by referring to the data of the system list described above. In step S130, a system circuit diagram is created based on the read image data. It is also possible to display the created system circuit diagram. The created system circuit diagram is equivalent to the connection diagram image of FIG. 14 described in the previous embodiment, and includes the specified parts / wiring and other parts / wiring, but the parts other than the specified parts / wiring. • Wiring is only included in the circuit diagram at this stage. The system circuit diagram in this state is a circuit diagram including the specified parts / wiring and other parts / wirings as shown in the upper part of FIG. 19, for example.

  In subsequent steps S140 to 190, the margin area is defined in the system circuit diagram equivalent to the connection diagram image (see FIG. 15), and the image data processing of the system circuit diagram for removing the margin area (see FIGS. 16 to 18). ), Creating a connection diagram based on the processed image data (see FIG. 18B), and through step S200, display and print the connection diagram. In other words, margin definition / data processing as shown in FIGS. 15 to 18 is performed in a system circuit diagram including the specified parts / wiring and other parts / wiring as shown in the upper part of FIG. Therefore, when the margin is defined in the middle part of FIG. 19, such margin regulation is performed with the system circuit diagram in the upper part of FIG.

  Even in the connection display system 10 of the other embodiments described above, although it has image data for drawing a system circuit diagram, it is necessary to create and display a connection diagram so as to assist in operations such as maintenance and inspection. When the operator (user) simply designates the display target, the user can display the connection diagram in which the parts corresponding to the display target are connected by wiring and easily recognize the connection diagram. The various effects described above can be achieved.

  Next, a modified example will be described. FIG. 21 is a block diagram illustrating a schematic configuration of a connection display system 50 according to a modification. This modification is characterized in that a connection display system is configured by a client computer that is a user terminal and a server that is communicably connected to the computer. That is, in this modification, the computer 11 shown in FIG. 2 is provided as a client computer, and the computer 11 is connected to the server 30 via a network. In this case, the computer 11 has a network control circuit 39 as shown in FIG.

  As shown in FIG. 21, the server 30 includes a CRT display 32, a keyboard 34, a mouse 36, an HDD 38, a network control circuit 39, and a CD drive 40 that reads the contents of the CD-ROM 20. , ROM 44 and CPU 46 are connected to each other. The connection display system 50 has the server 30 and the computer 11 connected via a network such as the Internet, an intranet, or a local area network (LAN).

  As described above, the program data is transferred to the HDD 38 via the CD drive 22 as well as various portable recording media (portable type) such as a floppy disk, a magneto-optical disk, and an IC card. It can also be transferred from a recording medium.

  The connection display system 50 is configured so that the search / display processing performed by the above-described embodiment is distributedly performed by the computer 11 and the server 30, and the computer 11 includes a web browser and a display control unit (not shown). Therefore, the computer 11 captures image information from the web browser via the Internet, and displays an image based on the information on the display 12 by the display control unit.

  The server 30 includes an http server (not shown) in order to exchange data with the computer 11 via the Internet, and has a highly versatile server environment that does not depend on the OS of the connected computer. In other words, the server 30 uses a Java servlet interface (Java Servlet Interface), a Java servlet execution environment, a Java execution environment, a search processing execution unit, and parts and wiring described in the embodiment as a circuit diagram on the xy plane. Various information storage units for storing data for drawing, etc., executing predetermined processing in response to a request from the web browser (computer 11), and storing the result in the web content as an html file To the web browser (computer 11). Although Java servlet is used to enhance the versatility of processing, if the client computer is fixed, an execution environment capable of distributed processing only with that computer can be used.

  In the connection display system 50 of this modification, the function is shared by the computer 11 and the server 30 which are client terminals. The computer 11 receives the designation of the display target by the user and transmits the data (display target specifying data) to the server 30. Since the server 30 stores various data described with reference to FIG. 3 and FIG. 20, based on the display target specifying data from the computer 11, as in step S 120 described above, the parts and wiring corresponding to the display target are stored. Data is read and transferred to the computer 11. Based on this data, the computer 11 executes the processes from steps S130 to S200 described above to display a connection diagram.

  Even in this modified example, the user can acquire a desired connection diagram as a simple state simply by specifying a display target. In this modification, drawing data and drawing position data necessary for drawing parts and wirings are stored in the server 30 instead of the computer 11, so that data can be collectively managed on the server 30 side.

  In addition, the processing from steps S120 to S200, which is the main processing for creating the connection diagram, is performed on the server 30 side, and the computer 11 waits for the user to specify the display target, transmits the result, and the server.
