  An embodiment of the present invention is shown below. The individual embodiments described below will help to understand various concepts, such as the superordinate concept, intermediate concept and subordinate concept of the present invention. Further, the technical scope of the present invention is determined by the scope of the claims, and is not limited by the following individual embodiments.

<Inspection (measurement) system>
FIG. 1 shows an example of an inspection system (displacement meter system) using a plurality of displacement meters. In FIG. 1, the computer 1 is a notebook PC, but it may be a general-purpose computer. The computer 1 includes a display unit 2 such as a liquid crystal display device and an input unit 3 such as a keyboard and a pointing device. Note that the display unit 2 and the input unit 3 may be stacked like a touch panel device. The computer 1 has a communication port such as a universal serial bus. The plurality of displacement meters 5 are connected to the communication port of the computer 1. If the number of displacement meters 5 is larger than the number of communication ports provided in the computer 1, the hub 4 may be employed. The plurality of displacement meters 5 measure the displacement of each part of the workpiece W that is the inspection object, the distance from the displacement meter 5 to the workpiece W, and the like. In general, the plurality of displacement meters 5 are fixed to a jig.

<Displacement meter>
FIGS. 2A, 2 </ b> B, and 2 </ b> C show configuration examples of the displacement meter 5. 2A, the displacement meter 5 includes a head H, a communication cable 6a, a relay unit 10, a communication cable 6c, and a connector 9. The head H measures the displacement and distance (hereinafter simply referred to as displacement) of the workpiece W by directly contacting the workpiece W, or measures the displacement without contacting. The former contact displacement meter has a high measurement accuracy but has a design durability. Therefore, the head H that has exceeded the designed endurance life must be replaced. The latter non-contact type displacement meter is a displacement meter that measures displacement using light or ultrasonic waves. Since the non-contact displacement meter does not come into contact with the workpiece W, the durability is longer than that of the contact displacement meter, but the measurement accuracy is low.

  An electrical signal indicating the displacement measured by the head H is transmitted to the relay unit 10 via the communication cable 6a. The communication cable 6a is an example of a signal line that is connected to the head and transmits an electrical signal. The relay unit 10 converts the electrical signal into a digital value and transmits it to the computer 1 via the communication cable 6 c and the connector 9. The relay unit 10 converts a digital value as a measurement result into an electrical signal conforming to the communication standard of the communication port of the computer 1 and transmits it to the computer 1. That is, the relay unit 10 functions as a relay unit that converts an electrical signal into a communication signal of the first communication standard. The connector 9 is attached to the communication port of the computer 1.

  FIG. 2B shows an example in which the function of the relay unit 10 is divided into a first relay unit 7 and a second relay unit 8. The first relay unit 7 and the second relay unit 8 are connected via a communication cable 6b. The first relay unit 7 has a function of converting an electrical signal received from the head H into a digital value. The second relay unit 8 has a function of converting a digital value, which is a measurement result, into an electrical signal conforming to the communication standard of the communication port of the computer 1 and transmitting it to the computer 1. Note that the head H can be exchanged in the displacement meter 5 shown in FIG. 2 (A) or FIG. 2 (B). That is, by reducing the functions of the head H, the head H can be made inexpensive.

  FIG. 2C shows an example in which the function of the relay unit 10 is mounted on the head H. Although the size of the head H increases, only the communication cable 6c exists between the computer 1 and the head H. That is, the displacement meter 5 can be simplified.

  FIG. 3 shows the function of the displacement meter 5 shown in FIG. The head H is provided with a measuring element 11 that generates an analog electric signal by moving in accordance with the displacement of the workpiece W. The ADC 21 is an analog-digital converter, and converts an analog electrical signal corresponding to the displacement into a digital signal (digital value). The control unit 22 performs a predetermined calculation on the digital value indicating the amount of displacement, turns on the indicator lamp 23 based on the lighting command received from the computer 1, and blinks the indicator lamp 23 based on the blink command. Further, the control unit 22 transmits the calculation result (measurement result) to the relay unit 10 through the communication unit 24. When receiving a head ID read command via the communication unit 24, the control unit 22 reads the head ID from the storage unit 25 and transmits it from the communication unit 24. The head ID is an example of identification information of the displacement meter.

  The relay unit 10 is traditionally called an amplifier, but does not need to have an amplification function. The control unit 32 of the relay unit 10 transmits the measurement result received via the communication unit 31 to the computer 1 via the communication unit 34 or the command received from the computer 1 via the communication unit 34. To the head H. The relay unit 10 may include an optional indicator lamp 33 or may be connected to the indicator lamp 33 via a signal cable. The control unit 32 may turn on or blink the indicator lamp 33 based on the command received from the computer 1. The control unit 32 may compare the tolerance data received from the computer 1 with the measurement result received from the head H and determine whether the measurement result is within the tolerance range. If the measurement result is within the tolerance range, the control unit 32 sets the color of the indicator lamp 33 to green as the measurement result is acceptable, and if the measurement result is not within the tolerance range, the measurement result is unacceptable. As an alternative, the color of the indicator lamp 33 may be set to red. The control unit 32 compares the measurement result with the tolerance and outputs pass / fail of the measurement result. When receiving the amplifier ID read command from the computer 1, the control unit 32 transmits the amplifier ID read from the storage unit 35 to the computer 1. The amplifier ID is an example of identification information of the displacement meter, and here is identification information of the relay unit 10. The control unit 32 may read the head ID from the head H in advance and store it in the storage unit 35. When receiving a head ID read command from the computer 1, the control unit 32 may read the head ID from the storage unit 35 and transmit it to the computer 1. The storage unit 35 ′ is an optional storage unit that stores a communication ID. The communication ID may be an address assigned to the USB device, an IP address, a COM port number, or the like. USB is an abbreviation for Universal Serial Bus. The communication unit 34 is a circuit that communicates with any one of the communication units included in the computer 1, and performs communication in accordance with standards such as USB, RS-232C, and Ethernet (registered trademark). The communication unit 34 may be a wireless communication unit compliant with a wireless LAN standard, an IoT (Internet of Thing) communication standard, or the like. In any case, the communication unit 34 is a communication circuit that can communicate with the computer 1.

  In the displacement meter 5 shown in FIG. 2B, the measuring element 11 is accommodated in the head H, and the remaining functions are accommodated in the first relay unit 7. That is, among the functions of the head H shown in FIG. 3, the function existing on the left side of the broken line is accommodated in the head H shown in FIG. Be contained. The second relay unit 8 has the function of the relay unit 10.

  In the displacement meter 5 shown in FIG. 2C, the relay unit 10 shown in FIG. 3 is omitted, and each function of the head H shown in FIG. As a result, the control unit 22 performs an operation on the measurement value instead of the control unit 32, and the communication unit 24 communicates with the computer 1 instead of the communication unit 34.

  As shown in FIG. 3, the communication unit (communication unit 34 and storage unit 35 ′) of the relay unit 10 may be a unit that can be detached from the main body of the relay unit 10. The user can select a communication unit that can be connected to the computer 1 from a plurality of communication units (eg, wired LAN, wireless LAN, RS-232C, short-range wireless communication, etc.) having different communication protocols and communication circuits. Become.

  As described above, the CPU 40 renders the measurement result and the like on the monitor screen created by the basic setting and customization, and displays the monitor screen on the display unit 2. A portion of the monitor UI excluding the monitor screen (controls such as buttons and menus) may be stored in the storage unit 42 as a template file.

<User interface>
Monitor Screen FIG. 6 is a view showing an example of the monitor UI 70 including the monitor screen 78. The monitor UI 70 is a user interface that the UI unit 51 displays on the display unit 2 based on the setting data 44. Various display objects are arranged on the monitor UI 70. The monitor screen 78 is a UI for displaying measurement results, calculation results, and the like acquired by the displacement meter 5. The setting button 71 is a button for instructing to switch from the monitor UI 70 to a UI for executing basic settings and customization of the monitor UI 70. The comprehensive determination component 72 is a display object that displays the comprehensive determination result. The image area 73 is an area for displaying an image of the workpiece W. The display object 74 that is a measurement result component is a display object that displays the measurement result itself of the displacement meter 5 and the calculation result obtained by calculation from the measurement result. The lead line 75 is a display object that connects the display object 74 and the image of the workpiece W or the image of the head H of the displacement meter 5. The lead line 75 assists the user in understanding the relationship between the display object 74 and the workpiece W or the head H. The switch button 76 is a button for instructing to switch between the monitor screen 78 and the list screen. The pointer 77 moves when the user operates the pointing device of the input unit 3 and is used to input an instruction. That is, the UI unit 51 changes the display position of the pointer 77 according to the operation amount of the pointing device of the input unit 3. The trigger button in the monitor UI 70 is a button for leaving logging information. When the preset button is pressed after selecting “all measured values” on the left, the target is set to zero. The preset reset button is a button for returning to a state before being preset.

  FIG. 7 shows an example of a monitor UI 70 including a list screen 79. When the UI unit 51 detects that the switching button 76 is operated through the input unit 3, the UI unit 51 displays a list screen 79 for displaying the measurement results and the calculation results in a list format on the display unit 2. When the switching button 76 is operated again, the UI unit 51 switches the list screen 79 to the monitor screen 78.

● Setting UI for setting monitor UI
(1) Basic setting (S11)
Sensor Setting When the creation unit 60 detects that the setting button 71 has been operated through the input unit 3, the creation unit 60 displays a user interface for setting or creating the monitor screen 78 on the display unit 2.

  FIG. 8 shows an example of a sensor setting UI 80 for executing settings related to the displacement meter 5. As shown in FIG. 8, when the setting button 71 is operated through the input unit 3, the creation unit 60 displays the sensor setting UI 80 on the display unit 2. The sensor setting UI 80 has four item buttons 81 for selecting setting items.

  The sensor setting area 83 executes an operation on an icon indicating a connection state of the displacement meter 5 connected to the computer 1, a text area for setting a sensor name (a name of the displacement meter 5 or a measurement result), and a measurement result. A switching unit for determining whether or not to output the measurement result from any of the IO ports, a switching unit for determining whether or not to display the measurement result on the monitor UI 70, and a blinking command for the indicator lamp 23 of the displacement meter 5 And a button for instructing to delete the displacement meter 5 from the sensor setting area 83. The setting unit 61 of the creating unit 60 acquires information on the displacement meter 5 recognized by the device management unit 54 from the device management unit 54 and lists the information in the sensor setting area 83. When detecting that the dummy sensor addition button 85 is operated, the setting unit 61 may add a virtual device (dummy device) that is not recognized by the device management unit 54 to the sensor setting area 83. For example, when the user plans to purchase the displacement meter 5 additionally, the display object of the displacement meter 5 can be arranged on the monitor UI 70 in advance. The threshold setting area 84 is a UI for setting a determination threshold (tolerance) for determining whether or not the measurement result is acceptable. When the measurement result is evaluated in five stages, four determination threshold values are required. For example, LL is a determination threshold corresponding to the lower limit value of the tolerance. LO is a determination threshold value larger than LL. HI is a determination threshold value larger than LO. HH is a determination threshold corresponding to the upper limit value of the tolerance. The comprehensive determination unit 53, the control unit 22, or the control unit 32 may compare the set determination threshold value with the measurement result to generate a determination result. For example, if the measurement result is less than LL, the control unit 22 transmits a determination result (LL determination output) indicating that the measurement result is less than LL to the computer 1. If the measurement result is less than LO and greater than or equal to LL, the control unit 22 transmits a determination result (LO determination output) indicating that the measurement result is less than LO and greater than or equal to LL to the computer 1. If the measurement result is less than HI and greater than or equal to LO, the control unit 22 transmits a determination result (GO determination output) indicating that the measurement result is less than HI and greater than or equal to LO to the computer 1. If the measurement result is less than HH and greater than or equal to HI, the control unit 22 transmits a determination result (HI decision output) indicating that the measurement result is less than HH and greater than or equal to HI to the computer 1. If the measurement result is HH or higher, the control unit 22 transmits a determination result (HH determination output) indicating that the measurement result is HH or higher to the computer 1. The control unit 22 may transmit raw measurement values to the computer 1 in addition to these determination results. These determinations may be executed by the control unit 32 or the comprehensive determination unit 53. The threshold setting area 84 may have an area for setting hysteresis. By setting the hysteresis, it is possible to stabilize the determination result even if the measurement result vibrates in a short time. The threshold setting area 84 may have an area for calibrating the measurement result of the displacement meter 5. For example, the measurement result when the displacement meter 5 is not in contact with the workpiece W can be calibrated to a preset value (usually zero). An area for accepting a span or offset for calibration may be provided in the threshold setting area 84.

  The monitor button 82 is a button for displaying the monitor UI 70 on the display unit 2. The custom button 86 is a button for displaying the custom setting UI on the display unit 2.

  The setting unit 61 stores the setting content set through the input unit 3 in the storage unit 42 as setting data 44.

Calculation Setting FIG. 9 shows an example of the calculation setting UI 90. The calculation setting UI 90 has four item buttons 81 for selecting setting items. As shown in FIG. 9, when the calculation setting button is operated through the input unit 3, the setting unit 61 displays the calculation setting UI 90 on the display unit 2.

  When the add button 91 is operated, the setting unit 61 adds calculation settings to the calculation setting area 92. The calculation setting includes a name given to the calculation setting, information indicating the type of calculation, a name of a displacement meter used for the calculation, and the like. When the edit button 95 is operated, the setting unit 61 displays a dialog box for setting the calculation contents on the display unit 2.

  FIG. 10 is a diagram showing an example of a dialog box 96 for setting calculation contents. A pull-down menu 97 is a UI for displaying the type of calculation in a list format. The dialog box 96 may have a text box for inputting a name given to the calculation setting. The pull-down menu 98 is a UI for selecting the displacement meter 5 whose measurement result is used for the selected type of calculation. The setting unit 61 may arrange a plurality of pull-down menus 98 in the dialog box 96 according to the selected type of calculation. The setting unit 61 generates a pull-down menu 98 from the list of displacement meters 5 listed in the sensor setting area 83. The setting unit 61 creates the setting data 44 so that the measurement result of the displacement meter 5 selected from the pull-down menu 98 is used for the calculation selected from the pull-down menu 97. A dialog box 96 shown in FIG. 10 is a dialog box for setting a thickness calculation for calculating the thickness of the workpiece W by adding the measurement results X1 and X2 of the two displacement meters 5. Examples of the types of calculation include maximum value calculation, minimum value calculation, flatness calculation, average value calculation, and the like. The maximum value calculation is an operation for obtaining the maximum value among the measurement values acquired from the plurality of displacement meters 5. The minimum value calculation is an operation for obtaining the minimum value among the measurement values acquired from the plurality of displacement meters 5. The flatness calculation is an operation for obtaining the difference between the maximum value and the minimum value as the flatness. The average value calculation is an operation for obtaining an average value of measurement values acquired from the plurality of displacement meters 5. Furthermore, the calculation which calculates | requires the twist and curvature of the surface of the workpiece | work W may be employ | adopted.

  The setting unit 61 stores the setting content set through the input unit 3 in the storage unit 42 as setting data 44.

Input / output setting FIG. 11 shows an input / output setting UI 100 for executing input / output setting. The input / output setting UI 100 is a UI for executing an output setting for outputting a signal to an external device (for example, PLC) connected to the computer 1 or an input setting for inputting a signal from the external device.

  Here, the “minimum input time” displayed in the IN setting item is the minimum holding time of the ON signal. If the signal is not continuously input over the minimum input time, the signal is not regarded as an ON signal. In a noisy environment, the “minimum input time” is set relatively long in order to prevent erroneous determination of ON. In this way, it is determined that the signal is ON only when a signal is input over the minimum input time. When “Use for logging trigger” is checked, the checked input item becomes a trigger for logging. Note that Switch 1 and IN 1 are OR conditions for determining signal input in either operation. If “Use for preset” is checked, presetting can be performed by inputting IN2.

Logging Setting FIG. 12 shows a logging setting UI 101 for executing logging setting. Logging means that the CPU 40 records the comprehensive determination result and measurement result of the work W in the storage unit 42 as a log.

The display color of the bar 126 is displayed in the first color (eg, green) if the measurement result or calculation result is within the tolerance, and the second color (eg, red) if the measurement result or calculation result is not within the tolerance. May be displayed.

<Summary 1>
As described above, the displacement meter 5 is an example of a displacement meter that measures the distance to the measurement object or the displacement of the measurement object. An example of the measurement object is a workpiece W. The computer 1 is an example of a computer that is connected to a plurality of displacement meters 5 and controls the plurality of displacement meters 5. The program 43 is an example of a program executed on the computer 1. When the CPU 40 of the computer 1 executes the program 43, the computer 1 functions as a creation unit (for example, a creation unit 60) that creates a monitor screen for the user to monitor the measurement result of each displacement meter 5. The creation unit 60, the custom unit 62, and the component placement unit 63 function as a placement unit that places a display object 74 for displaying the measurement result of each displacement meter on the image of the workpiece W. As shown in FIG. 7 and FIG. 20, as one of the display objects, the pass / fail of a measurement object obtained by logically calculating the pass / fail of a plurality of measurement results determined from a comparison between a plurality of measurement results and tolerances is shown. A display object to be displayed (eg, comprehensive judgment component 72) may be included. In the inspection system configured by connecting the plurality of displacement meters 5 to the computer 1 in this way, the user can easily see whether the workpiece W is accepted or not, so that the usability will be improved.

  As described with reference to FIG. 14 and the like, the image change unit 65 and the image change button 112 function as import means for importing the image of the work W. This makes it easier for the user to understand what kind of work W is being inspected through the computer 1.

  As described with reference to FIGS. 15 and 22C and the like, the display object 74 that displays the measurement result of each displacement meter 5 is a bar graph indicating the measurement value that is the measurement result and the tolerance for the measurement value. There may be. This makes it easier for the user to visually grasp the relationship between the measurement result and the tolerance. A gauge may be employed instead of the bar graph.

  As described with reference to FIG. 4, the calculation unit 52 functions as a calculation unit that acquires the calculation result by calculating the measurement value and the tolerance. The calculation unit 52 may be provided in each displacement meter 5. The comprehensive determination unit 53 functions as a determination unit that determines pass / fail of the measurement object based on the calculation result.

  As described with reference to FIG. 6 and the like, the monitor screen 78 is an example of a first monitor screen including a display object 74 that displays the measurement result of each displacement meter 5 and an image of the workpiece W. As described with reference to FIG. 7, the list screen 79 is an example of a second monitor screen that does not include an image of the workpiece W and displays a list of measurement results of the displacement meters 5. The switching button 76 functions as switching means for switching between the monitor screen 78 and the list screen 79. The user can switch the user interface for displaying the measurement result according to his / her preference.

  As described above, the user changes the positions of various display objects by operating the pointer 77 through the input unit 3. That is, the custom unit 62 and the component arrangement unit 63 function as an arrangement changing unit that changes the arrangement of the display object in accordance with a change instruction input by the user.

  The setting data 44 created by the creation unit 60 in response to a user operation and stored in the storage unit 42 is an example of a setting file indicating the image of the work W constituting the monitor screen 78 and the position of the display object. In general, the setting data 44 is a project that integrally manages various information such as the name and file path of the image file storing the image of the work W, the position of the display object, the information displayed on the display object, and the identification information of the displacement meter 5. Become a file.

  As described with reference to FIGS. 2 and 3, the displacement meter 5 includes the head H that contacts the workpiece W and a transmission unit that transmits to the computer 1 an electrical signal indicating the displacement of the workpiece W measured by the head H. And have. For example, the communication unit 24 or the communication unit 34 mounted on any of the head H, the relay unit 10, the first relay unit 7, and the second relay unit 8 is an example of a transmission unit.

  As shown in FIG. 23A, the creation unit 60 creates a component management table 131 that associates the identification information (eg, head ID) acquired from the head H and the identification information (eg, component ID) of the display object. Then, it may be stored in the storage unit 42. The creation unit 60 acquires a communication ID (a communication port number such as a COM port number) assigned to the displacement meter 5 through the device management unit 54. The creation unit 60 transmits a command for requesting identification information to the displacement meter 5 based on the acquired communication port number. The request command for the head H and the request command for the amplifier such as the relay unit 10 may be different. As described above, when receiving the request command, the control unit 22 reads the head ID from the storage unit 25 and transmits it to the computer 1. Similarly, when receiving the request command, the control unit 32 reads the repeater ID (amplifier ID) from the storage unit 35 and transmits it to the computer 1. In addition, about the display object 74 which displays the calculation result acquired by calculating the several measurement result acquired by the several displacement meter 5, about the several displacement meter 5 used in order to acquire a calculation result The head ID is associated with the component ID. The creation unit 60 may also associate the relay ID and the communication ID associated with the head IDs of the plurality of displacement meters 5 with the component ID.

  As shown in FIG. 23B, the device management unit 54 creates a device management table 132 for managing each displacement meter 5 and stores it in the storage unit 42. The device management table 132 may be a part of the setting data 44. The device management unit 54 registers the communication ID, repeater ID, and head ID in the device management table 132 in association with each other. For example, the device management unit 54 issues a command to each communication ID acquired from the device manager in order, thereby acquiring the relay ID and the head ID and associating them with the communication port number. Thereby, the device management table 132 is created. When detecting that the reload button is operated in the sensor setting UI 80 illustrated in FIG. 8, the device management unit 54 may update the device management table 132 by executing the same procedure.

  As described above, when detecting that the dummy sensor addition button 85 has been operated, the setting unit 61 adds a virtual device (dummy device) that is not recognized by the device management unit 54 to the sensor setting area 83. The creation unit 60 may associate any display object with the dummy sensor. As shown in FIG. 23A, the relay ID and head ID may be given specific identification information that can be recognized as a dummy sensor.

  As described with reference to FIG. 6, FIG. 18, FIG. 19, and the like, the lead line arrangement unit 68 of the component arrangement unit 63 arranges a display object indicating the measurement location of each displacement meter 5 on the workpiece W image. Also good. This makes it easier for the user to visually understand the measurement location of each displacement meter 5. The display object indicating the measurement location may be a lead line. Further, an auxiliary display object such as a lead line may be arranged so as to connect the measurement location or the head H and the display object indicating the measurement result. This makes it easier for the user to visually grasp the relationship between the measurement result displayed by each display object and the displacement meter 5 that acquired the measurement result.

  As described with reference to FIG. 6 and the like, the selection unit 66 of the component placement unit 63 performs a calculation result obtained by performing a predetermined calculation on a plurality of measurement values acquired by the plurality of displacement meters 5 (example: A display object 74 that displays (width) may be further arranged with respect to the image of the workpiece W. For example, measurement values such as width cannot be measured unless a plurality of displacement meters 5 are used. Therefore, a display object for displaying a calculated value obtained by calculation from measured values acquired using a plurality of displacement meters 5 may be arranged on the monitor screen 78. Thereby, the user will be able to confirm on the monitor screen 78 also the measurement results (calculated values) of each part of the workpiece H that cannot be measured by the single displacement meter 5.

  When the UI unit 51 is switched from the creation mode of the monitor screen 78 to the inspection mode for executing the inspection of the workpiece W, the UI unit 51 renders the measurement result of each displacement meter 5 on the display object 74 or the like to display the monitor screen 78 on the display device ( It may function as a rendering means for displaying on the display unit 2). Such switching is executed when the monitor button 82 is operated. As described above, the program 43 may provide an integrated environment having the monitor screen 78 creation mode and the inspection mode (monitor mode). As a result, the user can easily create the monitor screen 78 and execute the inspection. In addition, the user often notices points to be improved on the monitor screen 78 by actually executing the inspection. In the past, it was necessary to inform the software vendor of the improvement points over the phone and wait for the software to be improved. However, according to the present embodiment, the user can operate the setting button 71 to immediately switch to the creation mode and correct the monitor screen 78, so that usability is improved. Therefore, such an integrated environment would be useful.

<Updating the monitor UI>
In the inspection system formed by connecting the plurality of displacement meters 5 to the computer 1 as described above, any one of the displacement meters 5 may be replaced with another displacement meter 5. In particular, since the contact-type head H has a design life (service life), the head H that has reached the end of its life is replaced with a new one. It is also conceivable that the user accidentally breaks the head H or the relay unit (amplifier). In this way, the head H and the like may be exchanged. As described with reference to FIG. 23A, the component ID of the display object 74 is managed in association with the head ID of the head H and the like. Therefore, if the head H or the like is replaced, an update operation for associating the head ID of the replaced head H with the component ID occurs. It would be unusable for the user to perform the update work manually. In addition, it would be convenient if the parts management table 131 is automatically updated to match the user's intention as much as possible, and the monitor UI is also automatically updated. For example, in the parts management table 131 and the device management table 132, it is assumed that only one display object 74 of the plurality of display objects 74 cannot find the corresponding head H, and instead find another head H. Is done. In this case, there is a high possibility that a head H that the device management unit 54 can no longer find has been replaced by another newly found head H by the user. Therefore, the device management unit 54 may associate the component ID of the display object 74 associated with the head ID of a certain head H with the head ID of another head H. However, if such an association update is performed after obtaining the user's consent, it will easily reflect the user's intention.

  An inspection system used in one work room may be moved to another work room. The inspection system will be disassembled in order to carry out the mobile work efficiently. It is not easy for the user to remember to which relay section a large number of heads H are connected in the work of reassembling the inspection system in another work room (setup change). Although the first head H and the first relay unit form a pair before the movement, the first head H and the second relay unit may form a pair after the movement. Therefore, even if the connection relationship between the head H and the relay unit is changed before and after the movement, any head H used before the movement is connected to the computer 1 via any relay unit. Insofar as a monitor UI should be provided without placing an additional burden on the user.

<Update device management table>
The device management unit 54 acquires a communication ID related to the displacement meter 5 from the device manager at a predetermined timing. The predetermined timing may be, for example, a periodic timing or a timing at which the CPU 40 detects that a reload button arranged on the sensor setting UI 80 or the like has been operated. The device management unit 54 transmits a repeater ID and head ID read command to the communication port to which the displacement meter 5 is connected. As a result, the command is transferred to each displacement meter 5 via the communication unit 41. As described above, each displacement meter 5 transmits the repeater ID (omitted in the embodiment where no repeater is present) and the head ID to the computer 1. The device management unit 54 updates the association between the acquired communication ID, head ID, and repeater ID in the device management table 132. When the content of the device management table 132 is changed, the device management unit 54 notifies the creation unit 60 of the change.

<Update parts management table>
FIG. 24 is a block diagram showing functions involved in the update processing of the component management table 131. FIG. 25 is a flowchart showing the update process of the component management table 131. Functions already described are given the same reference numerals. Upon receiving a notification indicating that the device management table 132 has been updated from the device management unit 54, the creation unit 60 starts an update process for the component management table 131. At this time, as described above, the device management table 132 is updated to the latest one.

  In S <b> 21, the CPU 40 (device determination unit 141) determines whether all the heads H registered in the component management table 131 are present (whether connected to the computer 1). For example, the device determination unit 141 determines whether the head ID of the displacement meter 5 stored in the component management table 131 matches the head ID stored in the device management table 132. That is, the device determination unit 141 determines whether the head IDs of all the displacement meters 5 stored in the component management table 131 exist in the device management table 132. If all the heads H registered in the component management table 131 exist, the CPU 40 proceeds to S22.

  In S22, the CPU 40 (device determination unit 141) determines whether there is a change in the combination of the head ID and the repeater ID. For example, the device determination unit 141 determines whether the combination of the head ID and the repeater ID registered in the component management table 131 matches the combination of the head ID and the repeater ID registered in the device management table 132. judge. The head H may be a detachable and replaceable product from the relay unit 10. If the head ID is unique product identification information such as a serial number, when the head H is replaced, the head ID acquired by the device management unit 54 is also changed. However, if the relay unit 10 has not been replaced, the relay ID acquired by the device management unit 54 is maintained. Therefore, the combination of the head ID and the repeater ID is changed. Note that a combination including a communication ID may be an update target. That is, the device determination unit 141 may determine whether the combination of the head ID, the repeater ID, and the communication ID (such as the communication port number) matches or does not match. If there is no change in the combination of the head ID and the repeater ID, the CPU 40 ends the update process. If there is a change in the combination of the head ID and the repeater ID, the CPU 40 proceeds to S23.

  In S23, the CPU 40 (update unit 144) sets the head ID and repeater ID registered in the component management table 131 so as to match the combination of the head ID and repeater ID registered in the device management table 132. Update the combination.

  Thus, although the head ID is not changed, the repeater ID associated with the head ID may be changed. This is a phenomenon that occurs during setup change. Therefore, even if there is no change in the head ID associated with the component ID, when the repeater ID or the like is changed, the repeater ID or the like is updated. Further, the communication ID may change depending on the order in which the displacement meter 5 is connected to the computer 1. Therefore, it will be convenient if the communication ID associated with the component ID is also automatically updated.

  If it is determined in S21 that one or more heads H do not exist, the CPU 40 proceeds to S24. In S24, the CPU 40 (device determination unit 141) determines whether the number of unknown head IDs and the number of undetectable head IDs are one each. An unknown head ID is a head ID that is not a known head ID. That is, an unknown head ID is a head ID that has been newly registered in the device management table 132 but has not yet been registered in the component management table 131. The undetectable head ID is a head ID that has been registered in the component management table 131 but has been deleted from the device management table 132. In other words, the undetectable head ID is a head ID that the device management unit 54 has become unable to acquire from any displacement meter 5.

  FIG. 26A shows that one head ID (for example, CCCC) registered in the component management table 131 cannot be detected. FIG. 26B shows that one head ID (eg, CCCC) is deleted from the device management table 132, and instead, one unknown head ID (eg, DDDD) can be acquired. Is shown. As described above, in the case where one undetectable head ID is generated and one unknown head ID is generated, there is a possibility that the user has replaced one head H with another head H. high. In this case, the measurement position itself will not be changed. If the CPU 40 determines that the number of unknown head IDs is one and the number of undetectable head IDs is one, the process proceeds to S25.

  In S25, the CPU 40 (update unit 144) associates the unknown head ID with the component ID instead of the undetectable head ID. That is, the update unit 144 associates an unknown head ID (eg, DDDD) with a component ID (eg, horizontal bar 2) associated with a head ID (eg: CCCC) that cannot be detected in the component management table 131. FIG. 26C shows the component management table 131 updated by the update unit 144. Note that the update unit 144 acquires a communication ID and a relay ID associated with an unknown head ID (eg, DDDD) from the device management table 132 and updates the communication ID and relay that are also updated in the component management table 131. Register the ID.

  When determining in S24 that the number of unknown head IDs and the number of undetectable head IDs are not one each, the CPU 40 proceeds to S26. In S <b> 26, the CPU 40 (device determination unit 141) determines whether any of the repeater IDs associated with the unknown head ID newly discovered by the device management unit 54 is a known repeater ID. As described above, only the head H attached to the relay unit 10 may be replaced with a new one. In this case, there is a high possibility that the measurement position itself is not changed only by replacing the head H.

  FIG. 27A shows an example of the component management table 131 in which two head IDs (for example, AAAA and BBBB) cannot be detected. FIG. 27B shows an example of the device management table 132 in which two unknown head IDs (eg, GGGG and HHHH) are newly registered. As can be seen from a comparison between the component management table 131 and the device management table 132, it can be seen that although the head ID has been changed from “AAAA” to “GGGG”, the repeater ID “1111” has not been changed. Similarly, although the head ID is changed from “BBBB” to “HHHH”, it can be seen that the repeater ID “2222” is not changed. Therefore, there is a high possibility that the head H whose head ID is “AAAA” is replaced with the head H whose head ID is “GGGG”. Similarly, there is a high possibility that the head H whose head ID is “BBBB” is replaced with the head H whose head ID is “HHHH”. In this way, if the repeater ID associated with the unknown head ID newly discovered by the device management unit 54 is any known repeater ID, the CPU 40 proceeds to S27.

  In S27, the CPU 40 (update unit 144) associates the unknown head ID based on the relay ID with the component ID associated with the head ID that has become undetectable. For example, the update unit 144 searches the device management table 132 for the repeater ID (example: 1111) associated with the head ID (example: AAAA) that has become undetectable, and repeater ID (example: 1111). An unknown head ID (for example, GGGG) associated with is acquired. Further, the update unit 144 associates an unknown head ID (eg, GGGG) with the component ID (eg, vertical bar 1) associated with the head ID (eg, AAAA) that has become undetectable, thereby managing the components. Update the table 131. Similarly, the update unit 144 searches the device management table 132 for the repeater ID (example: 2222) associated with the head ID (example: BBBB) that has become undetectable, and repeater ID (example: 2222). ) To obtain an unknown head ID (eg, HHHH) associated with. Furthermore, the update unit 144 associates an unknown head ID (eg, HHHH) with a component ID (eg, horizontal bar 1) associated with a head ID (eg, BBBB) that has become undetectable, thereby managing the component. Update the table 131. FIG. 27C shows the updated component management table 131. If the relay ID has not been changed but the communication ID (communication port number) has been changed, the updating unit 144 acquires the communication ID together with the head ID from the device management table 132 and stores it in the component management table 131. sign up. Thus, the update unit 144 may update the head ID and the communication ID using the repeater ID as a key.

  If at least one of the known relay IDs registered in the component management table 131 in S26 is not registered in the device management table 132, the CPU 40 proceeds to S28. FIG. 28A shows the component management table 131 in which two head IDs cannot be detected. FIG. 28B shows the device management table 132 in which two head IDs cannot be detected, and the two relay IDs associated with them cannot be detected. In the device management table 132 shown in FIG. 28B, three unknown displacement meters 5 having head IDs and repeater IDs different from the known displacement meters 5 are newly registered. In this case, the CPU 40 cannot accurately identify which displacement meter 5 (head H) the displacement meter 5 (head H) that has become undetectable has been replaced. In S <b> 28, the CPU 40 (output unit 142 or setting unit 61) highlights the head ID that has become undetectable. For example, the output unit 142 or the setting unit 61 may highlight the sensor name in red or the like in the sensor setting area 83. Alternatively, the output unit 142 may highlight the object 124 indicating the sensor name in the display object 74. The output unit 142 may highlight the display object 74 itself, the leader line 75 connected to the display object 74, and the icon (image) of the displacement meter 5. It is sufficient that the highlight display is a display format that can be visually discriminated, and any of color change, blinking, message addition, and the like may be used.

<Acceptance of update>
The head ID that has become undetectable in steps S23, S25, and S27 described above is automatically replaced with another head ID. However, the user may think that manual operation is required again when the head H is replaced because the displacement meter 5 is associated with each display object 74 by manual operation in the process of creating the monitor UI. . In such a case, the user may be relieved by automatically informing the user that the update has been applied. Further, the user may exchange the head H with another intention. For example, while changing the measurement site | part in the workpiece | work W, the head H suitable for the measurement site | part may be employ | adopted. Therefore, usability will be improved if a means for notifying or obtaining the user's consent before or after executing the automatic update is provided.

  FIG. 29A is a flowchart showing S23, S25 and S27 as subroutines.

  In S31, the CPU 40 (update unit 144) executes the update process described in relation to S23, S25, and S27.

  In S <b> 32, the CPU 40 (output unit 142) outputs a message regarding update to the display unit 2. The message regarding the update may be a message indicating that the association of the head ID or the like with respect to the component ID has been updated, a message for requesting post-update approval, or the like.

  FIG. 30 is a diagram showing an example of a message for requesting an update. The dialog 150 includes a message that the update has been executed and the update is requested. The dialog 150 may have a button 151 for accepting consent. The acceptance accepting unit 143 accepts acceptance of automatic update according to the operation of the button 151. The dialog 150 may be additionally provided with a cancel button for canceling the automatic update.

  FIG. 29B is another flowchart showing S23, S25 and S27 as subroutines. This indicates a pre-acknowledgement type update process.

  In S <b> 41, the CPU 40 (output unit 142) outputs a message (for example, dialog 150) requesting approval of update to the display unit 2.

  In S <b> 42, the CPU 40 (acceptance accepting unit 143) determines whether or not an instruction indicating that the user has accepted the update is input through the input unit 3. For example, the acceptance of the update may be that the button 151 has been pressed. Further, the rejection of the update may be that the cancel button has been pressed. If the update is accepted, the CPU 40 proceeds to S43.

  In S43, the CPU 40 (update unit 144) executes the update process described in relation to S23, S25, and S27. On the other hand, if the update is not accepted, the CPU 40 proceeds to S44.

  In S44, the CPU 40 (custom unit 62) executes a manual update by the user. For example, when the display object 74 highlighted in the customization UI 110 is clicked with the pointer 77, the custom unit 62 displays a list of selectable head IDs on the display unit 2. The custom unit 62 starts editing the component ID of the display object 74 selected by clicking. The UI displayed at this time will be a UI as shown in FIG. The custom unit 62 acquires the head ID and relay ID of the displacement meter 5 selected from the list from the device management table 132 and updates the component management table 131 by associating it with the component ID of the display object 74 selected by clicking. To do. Thus, the user will be able to create a monitor UI that suits his / her intention by selecting automatic update or manual update.

<Flashing of the head>
A large number of displacement meters 5 are positioned with respect to the workpiece W as shown in FIG. Many displacement meters 5 are fixed or supported by a jig or the like. As the number of displacement meters 5 increases, the user must check whether the relationship between the display object 74 on the monitor screen 78 and the displacement meter 5 actually installed on the workpiece W is correct. Further, the user will confirm whether the relationship between the name of the displacement meter 5 displayed on the monitor screen and the actual displacement meter 5 is the relationship intended by the user. In such a case, it would be convenient if an instruction for lighting or blinking the indicator lamp 23 of the displacement meter 5 or the indicator lamp 33 of the relay unit 10 can be input through the monitor UI or the customized UI.

  FIG. 31 shows a serial number (head ID) confirmation UI 160 called from the sensor setting UI 80 or the like. The list unit 145 of the setting unit 61 reads the identification information of the head H, the sensor name, and the like from the component management table 131 to create a list, and renders the list on the sensor setting UI 80. The sensor setting UI 80 is provided with a blink button 162 for each displacement meter 5. The selection unit 146 of the setting unit 61 detects the flashing button 162 clicked by the user, and notifies the lighting control unit 147 of the head ID corresponding to the detected flashing button 162. The lighting control unit 147 reads the communication ID associated with the notified head ID from the device management table 132, and transmits a blink command of the head H based on the read communication ID. The displacement meter 5 that has received the blink command blinks the indicator lamp. This makes it easier for the user to grasp the relationship between the displacement meter 5 on the user interface and the actual displacement meter 5.

  FIG. 32 shows another UI for blinking an arbitrary displacement meter 5. Here, a blinking instruction is input from the monitor screen 78. The blinking button 162 may be provided on the icon (image) of the displacement meter 5, but the blinking button 162 may be provided on the display object 74 as shown in FIG. By comparing the monitor screen 78 with the actual displacement meter 5, the user can easily confirm whether the monitor screen 78 is correctly created (or whether the displacement meter 5 is correctly arranged).

  Here, an example in which the indicator lamp 23 of the head H blinks is used. However, the display color of the indicator lamp 23 may be changed, or the indicator lamp 23 may be switched from off to on. If the indicator lamp 23 is a liquid crystal display device, a special message may be displayed. In addition, when a sound source element such as a buzzer is employed instead of the indicator lamp 23, sound may be output from the head H. Further, when the head H has an air valve that blows out air, the air may be output from the head H by controlling the air valve.

  Note that the lighting control unit 147 may limit the number of indicator lamps 23 that can blink simultaneously among the plurality of displacement meters 5 to one. This is because it becomes difficult for the user to confirm the intended displacement meter 5 when the plurality of indicator lamps 23 blink.

<Summary 2>
As described above, the program 43 is connected to the first displacement meter and the second displacement meter that measure the distance to the measurement object or the displacement of the measurement object, and is executed in the computer 1 that controls the first displacement meter and the second displacement meter. Program. As described with reference to FIG. 23B, the device management unit 54 acquires identification information (for example, CCCC) of the first displacement meter from the first displacement meter, and also identifies identification information (for example, the second displacement meter). AAAA) functions as an acquisition means for acquiring from the second displacement meter. The identification information acquisition process can be executed when the program 43 is activated or when an acquisition instruction is input by the user. The device management table 132 stored in the storage unit 42 functions as a first storage unit that stores identification information of the first displacement meter and identification information of the second displacement meter. The component management table 131 stored in the storage unit 42 includes identification information of the first displacement meter and identification information of the first display object (for example, horizontal bar 2) that displays the measurement value obtained by the first displacement meter. 2nd which memorize | stores an association | association with the identification information (example: vertical bar 1) of the 2nd display object which displays the measurement information obtained by the 2nd displacement meter and the measured value obtained by the 2nd displacement meter while memorizing association It functions as a storage means. The UI unit 51, the creation unit 60, and the like are rendering means for rendering the measurement value obtained by the first displacement meter on the first display object, and rendering the measurement value obtained by the second displacement meter on the second display object. Function. As described with reference to FIG. 26, identification information (for example, CCCC) of the first displacement meter cannot be acquired, and identification information (for example, DDDD) of the third displacement meter may be acquired. is there. As described with reference to FIG. 30 and the like, the output unit 142 renders the measurement value obtained by the third displacement meter on the first display object in place of the identification information of the first displacement meter. It functions as an output means for outputting information for requesting consent to associate (associate) the identification information with the identification information of the first display object. As shown in FIGS. 26 (A) and 26 (C), the update unit 144 converts the identification information associated with the identification information (eg, horizontal bar 2) of the first display object into the identification information of the first displacement meter. Instead, it functions as changing means for changing to identification information (eg, DDDD) of the third displacement meter. Since information regarding consent is output to the user in this way, the user can easily understand that the association is executed by the computer 1, and usability will be improved.

  As described with reference to FIG. 29B, the consent accepting unit 143 functions as accepting means for accepting consent. When the prior acceptance is accepted by the acceptance acceptance unit 143, the updating unit 144 replaces the identification information associated with the identification information of the first display object with the identification information of the first displacement meter, instead of the identification information of the first displacement meter. change. If the association is updated on the premise of consent in this way, an update that is not intended by the user will be difficult to execute.

  As described with reference to FIG. 29A and the like, the output unit 142 may output information for requesting subsequent approval after the update unit 144 has executed the association change. Thus, by notifying the user that the recommended update has been executed, the user can grasp the fact of the update. In addition, the user will be able to confirm the update result and manually update the association manually. For example, when the update unit 144 detects that the display object 74 has been clicked, the update unit 144 acquires an association (record) from the part management table 131 for the clicked display object 74 and displays the association (record) on the display unit 2. Further, when detecting that the head ID is clicked in the displayed association, the updating unit 144 may display the device management table 132 on the display unit 2 and allow the user to select one head ID. The updating unit 144 updates the parts management table 131 by associating the head ID selected by the user with the display object 74 currently being updated. In the device management table 132 displayed on the display unit 2, a blink button 162 for blinking the indicator lamp 23 of each head H may be arranged. This makes it easy for the user to check whether the selected head ID is the head ID of the head H intended by the user. As described above, a function may be provided in which the user manually corrects the automatic update by the computer 1.

  As described with reference to FIGS. 2 and 3, each of the first displacement meter, the second displacement meter, and the third displacement meter is a head H that converts the distance to the measurement object or the displacement of the measurement object into an electrical signal. Relay means for relaying electrical signals to the computer 1 (for example, the relay section 10, the first relay section 7 and the second relay section 8), a connector 9 for connecting the relay means and the computer 1, and each displacement meter 3rd storage means (for example, storage parts 25, 35, and 35 ') which memorize the discernment information (example: head ID, repeater ID, communication ID, etc.). Here, the 3rd memory | storage means may memorize | store the identification information of the head H as identification information of each displacement meter. Further, as shown in FIG. 3, the third storage unit may be a storage unit 25 provided in the head H. As shown in FIG. 3, the third storage unit is provided in the relay unit, and may be a storage unit 35 that stores the identification information of the head acquired from the head H. The third storage unit may be a storage unit 35 that stores the identification information of the relay unit (eg, repeater ID) as the identification information of each displacement meter 5. The head H may be a replaceable head. As described with reference to FIG. 3, the third storage unit is a storage unit 25 that is a fourth storage unit that stores the identification information of the head H, and a storage that is a fifth storage unit that stores the identification information of the relay unit. Part 35 may be included. In addition, the component management table 131 serving as the second storage unit includes identification information (eg, head ID) of the head H constituting each displacement meter 5 and identification information (eg, head ID) constituting each displacement meter 5 as identification information of each displacement meter 5. : Repeater ID) may be stored in association with the identification information (eg, component ID) of the display object corresponding to each displacement meter 5.

  As described with reference to FIGS. 25 and 27, the device determination unit 141 acquires the identification information (for example, AAAA) of the head H of the first displacement meter stored in the component management table 131 by the device management unit 54. If the identification information (example: GGGG) of another head H is obtained through the relay unit (relay ID: 1111) of the first displacement meter, it is determined that the head H of the first displacement meter has been replaced. May be. The output unit 142 may output information asking for permission to associate (associate) the identification information of another bed H with the identification information of the first display object. When the acceptance is accepted by the acceptance accepting unit 143, the updating unit 144 identifies the identification information of another bed H (for example, the vertical bar 1) with respect to the identification information (for example, the vertical bar 1) stored in the parts management table 131. Example: GGGG) may be associated. The state in which the head ID stored in the component management table 131 cannot be acquired from any displacement meter 5 and another head ID is acquired instead is the state in which the head H is replaced. Let's go. Therefore, the burden on the user will be reduced by updating the association of the head ID.

  By the way, the head H may not be replaced, and only the relay unit 10 may be replaced. The identification information of the relay unit 10 of the first displacement meter stored in the component management table 131 cannot be acquired by the device management unit 54, and the identification information of the head H of the first displacement meter is acquired through another relay unit 10. It will be done. In this case, the device determination unit 141 may determine that the relay unit of the first displacement meter has been replaced. The output unit 142 may output information asking for permission to associate the identification information of another relay means that relays the identification information of the head H of the first displacement meter with the identification information of the first display object. When the acceptance is accepted by the acceptance accepting unit 143, the updating unit 144 may associate the identification information of another relay unit with the identification information of the first display object stored in the parts management table 131. Thus, when the relay unit 10 is replaced without replacing the head H, the updating unit 144 may update the association of the relay unit 10 with the relay ID, the component ID, and the head ID. This association may also be updated by the above-described post-approval.

  By the way, it can be considered that the displacement meter 5 including the head H and the relay unit 10 is replaced with another displacement meter 5. That is, it becomes impossible for the device management unit 54 to acquire both the identification information of the head of the first displacement meter and the identification information of the relay means stored in the component management table 131, and the identification of the head H of the third displacement meter. Information and identification information of the relay means may be acquired. In this case, the device determination unit 141 may determine that the first displacement meter has been replaced with the third displacement meter. The output unit 142 may output information asking for permission to associate the identification information of the head of the third displacement meter and the identification information of the relay unit with the identification information of the first display object. When the acceptance is accepted by the acceptance accepting unit 143, the update unit 144 uses the identification information of the head of the third displacement meter and the identification information of the relay unit with respect to the identification information of the first display object stored in the parts management table 131. May be associated with each other. Thus, even if the head H and the relay unit 10 are exchanged at the same time, the newly found head H and the relay unit 10 can be associated with the component ID of the display object. This association may also be updated by the above-described post-approval.

  As described with reference to FIGS. 3, 31, and 32, each of the first displacement meter, the second displacement meter, and the third displacement meter is turned on in response to a lighting instruction output from the computer 1. You may have. As described with reference to FIG. 3, the indicator lamp 23 may be provided on at least one of the head H and the repeater. The indicator lamp 23 may be provided on any component as long as it is a component existing between the connector 9 and the head H. For example, the indicator lamp 23 may be provided on the cables 6a, 6b, 6c, and the like.

  As described with reference to FIG. 31, the list unit 145 functions as a list unit that displays a list of a plurality of displacement meters 5 connected to the computer 1. The selection unit 146 and the blink button 162 function as a selection unit that selects one displacement meter from among the plurality of displacement meters 5. The lighting control unit 147 functions as a lighting control unit that lights the indicator lamp 23 of the displacement meter 5 selected by the selection unit 146 or the blink button 162. As a result, the user can turn on the indicator lamp 23. This will be useful when confirming the correspondence between the display object 74 and the actual displacement meter 5 or the like.

  As described with reference to FIGS. 2 and 3, there are various variations in the function sharing between the head H and the repeater. Further, a configuration different from the configuration shown in FIG. 3 may be adopted. For example, the relay unit 10 includes an AD converter (eg, ADC 21) that performs analog / digital conversion on an electrical signal output from the head H, and a transmission unit (eg, communication unit) that transmits a digital value output from the AD converter to the computer 1. 24). In this case, the storage unit 25 that stores the identification information of the head and the ADC 21 may be housed in one housing (the housing of the relay unit 10). Further, the relay unit may be the second relay unit 8. In this case, an AD converter is provided between the head H and the second relay unit 8 for analog / digital conversion of the electrical signal. As described above, the first relay unit 7 will be provided with an AD converter. In this case, the storage unit 25 and the AD converter may be housed in the housing of the first relay unit 7. As described with reference to FIG. 2C, the head H, the AD converter that performs analog / digital conversion of the electrical signal, and the third storage unit that stores the identification information of the head H are housed in one housing. May be.

  The second relay unit 8 and the relay unit 10 may be a universal serial bus device that converts an electrical signal into a serial signal of the universal serial bus standard. Most PCs have a universal serial bus. Therefore, the user will be able to connect a plurality of displacement meters 5 to the PC to form a simple inspection system.

  When the setup change is performed as described above, the computer 1 will be once shut down. Therefore, when the program 43 is activated, the device management unit 54 or the device determination unit 141 recognizes all the displacement meters 5 stored in the device management table 132 and all the displacements acquired by the device management unit 54. It will be determined whether the total 5 pieces of identification information match. If the two match, the output unit 142 does not have to display information regarding the approval of the association update. That is, since the head H is not replaced in the setup change, the user will want to maintain the relationship between the head H and the display object 74. Therefore, there is no need to output information about the association update.

  As described above, the creation unit 60 functions as a creation unit that creates a monitor screen for monitoring the measurement result of each displacement meter 5. The image changing unit 65 functions as import means for importing an image of the measurement object. The component placement unit 63 functions as a placement unit for placing a display object 74 for displaying the measurement result of each displacement meter with respect to the image of the measurement object. Moreover, the calculating part 52 and the comprehensive determination part 53 function as a calculation means which calculates the calculation result of the measurement result of a 1st displacement meter, and the measurement result of a 2nd displacement meter. The component placement unit 63 may place a display object 74 that displays the calculation result on the image of the measurement target. The lead line arrangement unit 68 functions as a giving unit that gives a lead line to the display object 74. Moreover, the icon which shows the measurement position of each displacement meter may be provided to the image of the measurement object. The creation unit 60 may arrange a display object 74 that displays a measurement result of a dummy displacement meter not connected to the computer 1 in an image of the measurement target. If the display object 74 for such a virtual displacement meter is arranged on the monitor screen 78, the burden of the arrangement work of the display object 74 when the displacement meter 5 is actually connected to the computer 1 is reduced. right. That is, the user can easily update the monitor screen 78 simply by executing the operation of associating the displacement meter 5 newly connected to the computer 1 with the display object 74 for the virtual displacement meter. Let's go. As shown in FIGS. 21 and 22, the measurement result of the virtual displacement meter is excluded from the comprehensive determination target so as not to affect the comprehensive determination.

  By the way, the plurality of displacement meters 5 may be connected to the computer 1 after the plurality of displacement meters 5 are fixed to the jig. Further, after the creation unit 60 arranges the display objects 74 of the plurality of displacement meters 5 on the image of the measurement object, the plurality of displacement meters 5 may be connected to the computer 1.

  Note that the creation unit 60 may arrange the N display objects 74 on the monitor screen 78 when the N displacement meters 5 are detected in a state where the parts management table 131 is not created (initial state). Thereby, the user will be able to complete the monitor UI only by correcting the display position of the display object 74.

  By the way, the UI unit 51 and the creation unit 60 function as a display control unit that displays each measurement value obtained by the plurality of displacement meters 5 on an associated display object among the plurality of display objects. In addition, when one displacement meter 5 among the plurality of displacement meters 5 is changed to another displacement meter 5, the output unit 142 displays a plurality of pieces of identification information of the other displacement meters acquired by the device management unit 54. Information for requesting consent to be associated with the identification information of the display object associated with the identification information of the one displacement meter may be output.

  As described with reference to FIG. 2B, the displacement meter 5 includes the head H that converts the distance to the measurement object or the displacement of the measurement object into an electric signal, and the first that is connected to the head H and transmits the electric signal. One signal line (example: cable 6a) and a first signal line are connected, and a first relay means (example: first relay section 7) that converts an electrical signal into a communication signal of the first communication standard; A first storage unit (eg, storage unit 25) that stores unique identification information is detachably connected between the first relay unit and the computer 1, and a communication signal of the first communication standard is transmitted to the communication of the second communication standard. You may have the 2nd relay means (example: 2nd relay part 8) which converts into a signal, and the 2nd memory | storage means (memory | storage part 35) which memorize | stores the specific identification information of a 2nd relay means. The second relay unit 8 uses the unique identification information (eg, head ID) of the head acquired from the storage unit 25 and the unique identification information (eg: repeater ID) of the second relay unit 8 acquired from the storage unit 35. You may transmit to the computer 1. As described with reference to FIG. 3, the displacement meter 5 may further include at least one indicator lamps 23 and 33 that are lit or blinked in response to a lighting instruction output from the computer 1. As described with reference to FIG. 2B, the displacement meter 5 is provided at the second signal line (for example, the cable 6c) connected to the second relay unit 8 and the end of the second signal line, You may further have the connector 9 connected to a computer. It is sufficient that the indicator lamp is provided anywhere from the connector 9 to the head H.

  In addition, the head H, the cable 6a, and the 1st relay part 7 may be integrated as a single unit. The head H may be exchanged in units of this. Moreover, the 2nd relay part 8, the cable 6c, and the connector 9 may be integrated as a single unit.

  The second relay unit 8 may be a communication device to which the computer 1 is assigned a COM port number. COM port numbers are often assigned in serial communication system communication standards.

  The head H and the first relay unit 7 may operate by being supplied with power via the connector 9, the cable 6 c, and the second relay unit 8. The connector 9 may be connected to the computer 1 via the hub 4.

  As described with reference to FIG. 25 and the like, the device determination unit 141 is stored in the storage unit 42 and a plurality of identification information acquired by the device management unit 54 from the plurality of displacement meters 5 connected to the computer 1. It functions as a determination means for determining whether or not a plurality of identification information items that match. When the plurality of pieces of identification information acquired from the plurality of displacement meters 5 connected to the computer 1 and the plurality of pieces of identification information stored in the storage unit 42 do not coincide with each other, the output unit 142 Information for requesting whether or not to update the association between the identification information of the plurality of connected displacement meters and the identification information of the plurality of display objects may be output. As described with reference to FIG. 29B, the update unit 144 may update the association when an instruction to accept the update is input.

  Identification of an unknown displacement meter in which one of the plurality of identification information acquired by the device management unit 54 from the plurality of displacement meters 5 connected to the computer 1 is not stored in the storage unit 42 Information, and it is determined that the identification information of one displacement meter 5 among the identification information of the plurality of displacement meters 5 stored in the storage unit 42 cannot be obtained, and an instruction to approve the update is input Then, the update unit 144 identifies the display object associated with the identification information of one displacement meter that cannot be obtained by the device management unit 54 among the identification information of the plurality of displacement meters 5 stored in the storage unit 42. The information may be associated with identification information of an unknown displacement meter.

  As described with respect to S28, when the output unit 142 cannot acquire the identification information of two or more displacement meters among the identification information of the plurality of displacement meters 5 stored in the storage unit 42 by the device management unit 54, The identification information of the two or more displacement meters may be emphasized and output. Note that the output unit 142 may output an error message.

  The relay unit 10 may be a plurality of relay units that are connected to the plurality of displacement meters 5 on a one-to-one basis and that transfer measurement results of the connected displacement meters 5 to the computer 1. The storage unit 42 stores the identification information of the plurality of display objects 74, the identification information of the plurality of displacement meters 5, and the identification information of the plurality of relay units 10 in association with each other. The device determination unit 141 obtains all the identification information of the plurality of relay units 10 stored in the storage unit 42 by the device management unit 54 and is not stored in the storage unit 42. Is acquired through one relay unit 10 among the plurality of relay units 10, the update unit 144 determines whether the identification information of the display object 74 associated with the identification information of the one relay unit 10 is unknown. Displacement meter identification information may be associated.
