[0010] Hereinafter, this embodiment will be described with reference to the drawings.

[0011] [1. Configuration of tensile testing machine] FIG. 1 is a diagram showing an example of the configuration of a tensile tester 1 according to this embodiment. The tensile tester 1 of this embodiment applies a test force F to a test piece TP to perform a tensile test to measure mechanical properties such as the tensile strength, yield point, elongation, and reduction of area of ​​the sample. The test force F is a tensile force. The tensile tester 1 includes a tester main body 2 that applies a test force F to a test piece TP, which is a material to be tested, to perform a tensile test, and a control unit 3 that controls the tensile test operation performed by the tester main body 2. The tensile tester 1 corresponds to an example of a "material testing machine."

[0012] As shown in FIG. 1, the testing machine main body 2 is configured by forming a load frame on a base 26 using a pair of support columns 28 and 29 and a yoke 13, and fixing a crosshead 10 to the support columns 28 and 29.

[0013] A hydraulic actuator 18 is disposed on the base 26, and a lower grip 22 for gripping the lower end of the test piece TP is attached to a piston rod 181 of the hydraulic actuator 18. An upper grip 21 for gripping the upper end of the test piece TP is attached to the crosshead 10 via a load cell 14.

[0014] The hydraulic actuator 18 has its piston rod 181 extended and retracted by a servo valve 20, which controls the direction and amount of pressure oil. As a result, the gap between the upper grip 21 and the lower grip 22 expands and contracts, and a test force F is applied to the test piece TP fixed between the upper grip 21 and the lower grip 22. The stroke of the hydraulic actuator 18, i.e., the displacement of the test piece TP, is detected by a differential transformer 19 attached to the hydraulic actuator 18.

[0015] The load cell 14 is a sensor that measures a test force F, which is a tensile load applied to the test piece TP, and outputs a test force measurement signal SG1 to the control unit 3. The differential transformer 19 is a sensor that measures the amount of displacement of the test piece TP and outputs a displacement measurement signal SG2 to the control unit 3 in accordance with the amount of displacement.

[0016] A displacement sensor 15 is disposed on the test piece TP. For example, a dumbbell-shaped test piece formed with a constricted center is used as the test piece TP. The displacement sensor 15 is a sensor that measures the distance between a pair of gauge points on the test piece TP to measure an elongation measurement value ED and outputs an elongation measurement signal SG3 to the control unit 3. The pair of gauge points are disposed above and below the constricted region of the test piece TP.

[0017] The control unit 3 includes a signal input / output device 40 and a main body control device 50. The signal input / output device 40 constitutes an input / output interface circuit that transmits and receives signals to and from the testing machine main body 2, and in this embodiment has a first sensor amplifier 42, a second sensor amplifier 45, a third sensor amplifier 43, and a servo amplifier 44. The first sensor amplifier 42 is an amplifier that amplifies the test force measurement signal SG1 output by the load cell 14 to generate a test force measurement value FD, and outputs the test force measurement value FD to the main body control device 50. The second sensor amplifier 45 is an amplifier that amplifies the extension measurement signal SG3 output by the displacement sensor 15 to generate an extension measurement value ED, and outputs the extension measurement value ED to the main body control device 50. The third sensor amplifier 43 amplifies the displacement measurement signal SG2 output by the differential transformer 19 and outputs a displacement measurement signal A3 indicating the displacement measurement value XD to the main body control device 50 as a digital signal. The servo amplifier 44 is a device that controls the servo valve 20 under the control of the main body control device 50. The main body control device 50 calculates a command value dX of the displacement measurement value XD and transmits a command signal A4 indicating the command value dX to the servo valve 20.

[0018] Based on operations from the user, the main body control device 50 controls the operation of the testing machine main body 2. Furthermore, the main body control device 50 causes the testing machine main body 2 to carry out a tensile test. In this embodiment, the “user” includes an operator who operates the testing machine main body 2 .

[0019] The main body control device 50 includes a computer having a storage device such as a hard disk drive (HDD) or a solid state drive (SSD), an interface circuit with the signal input / output device 40, and various electronic circuits. An A / D converter is provided in the interface circuit with the signal input / output device 40, and the analog signals of the test force measurement signal SG1, the extension measurement signal SG3 and the displacement measurement signal SG2 are converted into digital signals by the A / D converter.

[0020] [2. Configuration of the main control device] Next, the configurations of the main body control device 50 and the display control device 60 will be described with reference to Fig. 2. Fig. 2 is a diagram showing an example of the configurations of the main body control device 50 and the display control device 60 according to this embodiment. The main body control device 50 is configured by, for example, a personal computer. The main body control device 50 includes a first processor 51, a first memory 52, and a first communication interface 53. The first processor 51 is configured with a CPU (Central Processing Unit), an MPU (Micro-Processing Unit), and the like. The first memory 52 is configured by a ROM (Read Only Memory), a RAM (Random Access Memory), etc. The first memory 52 stores a first control program 521.

[0021] The main body control device 50 is also configured to be connectable to a plurality of optional devices PA. The optional devices PA include, for example, a strain gauge type extensometer PA1, a non-contact extensometer PA2, a recorder PA3, a chuck controller PA4, a marker controller PA5, a crosshead movement detection encoder PA6, and a shatterproof cover interlock PA7. For example, the chuck controller PA4 is a control unit for the hydraulic upper and lower grippers 21 and 22. Further, for example, the crosshead movement amount detection encoder PA6 is an encoder that measures the movement amount of the crosshead 10.

[0022] The first communication interface 53 is a communication interface that communicates with the display control device 60 in accordance with, for example, the USB (Universal Serial Bus) standard. The first communication interface 53 includes a connector for connecting a USB cable and an interface circuit for processing signals transmitted through the connector. The first communication interface 53 is an interface board having a connector and an interface circuit, and is connected to a main board on which the first processor 51 and the like of the main body control device 50 are mounted. Alternatively, the connector and interface circuit that constitute the first communication interface 53 are mounted on the main board of the first processor 51. The first communication interface 53 transmits various information to the display control device 60. Furthermore, firmware 531 is installed in the first communication interface 53. The first communication interface 53 controls communication with the display control device 60 by executing the firmware 531.

[0023] The main body control device 50 is not limited to a personal computer, and may be configured with one or more appropriate circuits such as integrated circuits such as IC chips and LSIs. The main body control device 50 may also be configured with, for example, a tablet terminal or a smartphone. The main body control device 50 may also include programmed hardware such as a DSP (Digital Signal Processor), FPGA (Field Programmable Gate Array), etc. The main body control device 50 may also include a SoC (System-on-a-Chip)-FPGA.

[0024] As shown in FIG. 2, the main body control device 50 includes a test execution section 511, a first communication control section 512, a test condition storage section 522, and a first version storage section 523. Specifically, the first processor 51 executes the first control program 521 stored in the first memory 52, thereby functioning as a test execution unit 511 and a first communication control unit 512. Furthermore, the first processor 51 executes the first control program 521 stored in the first memory 52, thereby causing the first memory 52 to function as a test condition storage unit 522 and a first version storage unit 523.

[0025] The test condition storage unit 522 stores the test conditions for the tensile test to be executed by the testing machine main body 2. In this embodiment, a case will be described in which the test conditions are stored in advance in the test condition storage unit 522.

[0026] The first version storage unit 523 stores first version information VE1. The first version information VE1 is version information of the firmware 531 installed in the first communication interface 53. Furthermore, every time the firmware 531 is installed in the first communication interface 53, the first version information VE1 stored in the first version storage unit 523 is updated.

[0027] The test execution unit 511 reads out the test conditions from the test condition storage unit 522, and causes the testing machine main body 2 to execute a tensile test in accordance with the read out test conditions.

[0028] The first communication control unit 512 causes the first communication interface 53 to execute communication with the display control device 60. For example, in response to a request from the display control device 60, the first communication control unit 512 reads out first version information VE1 from the first version storage unit 523 and transmits it to the display control device 60. The first communication control unit 512 also transmits to the control device 60 information about the optional device PA that is communicably connected to the main body control device 50.

[0029] [3. Configuration of display control device] Next, the configuration of the display control device 60 will be described with reference to FIG. The display control device 60 is configured by, for example, a personal computer, and includes a second processor 61, a second memory 62, a second communication interface 63, and a display mechanism 64. The second processor 61 is composed of a CPU, an MPU, and the like. The second memory 62 is configured with a ROM, a RAM, etc. The second memory 62 stores a second control program 621. The second control program 621 is configured as, for example, application software. Therefore, in the following description, the second control program 621 may be referred to as "software."

[0030] In this embodiment, the display control device 60 is configured as a personal computer, but is not limited to this. The display control device 60 may be configured as, for example, a tablet terminal, a smartphone, or the like.

[0031] Furthermore, in this embodiment, the display control device 60 is described as being communicatively connected to the main body control device 50 of the tensile tester 1, but is not limited to this. The display control device 60 may also be communicatively connected to the main body control device of another tensile tester. In other words, the display control device 60 is not a display control device dedicated to the tensile tester 1, but is a display control device shared with other tensile testers.

[0032] The second communication interface 63 is a communication interface that communicates with the main body control device 50 in accordance with, for example, the USB standard. The second communication interface 63 includes a connector for connecting a USB cable and an interface circuit for processing signals transmitted through the connector. The second communication interface 63 is an interface board having a connector and an interface circuit, and is connected to a main board on which the second processor 61 of the display control device 60 is mounted. Alternatively, the connector and interface circuit that constitute the second communication interface 63 are mounted on the main board of the second processor 61. The second communication interface 63 receives various information from the main body control device 50.

[0033] In this embodiment, the main body control device 50 and the display control device 60 communicate with each other in accordance with the USB standard, but the present invention is not limited to this. For example, the main body control device 50 and the display control device 60 may communicate wirelessly with each other in accordance with standards such as Ethernet (registered trademark) and Bluetooth (registered trademark).

[0034] The display mechanism 64 includes an LCD or the like, and displays various images on the LCD. The display mechanism 64 displays, for example, a display item setting screen 700 and a display item setting screen 800 in accordance with instructions from the display control unit 613. The display item setting screen 700 will be further described with reference to FIG. The display item setting screen 800 will be further described with reference to FIG.

[0035] The display control device 60 includes a first acquisition unit 611, a second acquisition unit 612, a display control unit 613, and a second version storage unit 622. Specifically, the second processor 61 executes the second control program 621 stored in the second memory 62, thereby functioning as a first acquisition unit 611, a second acquisition unit 612, and a display control unit 613. In addition, the second processor 61 executes the second control program 621 stored in the second memory 62, thereby causing the second memory 62 to function as a second version storage unit 622. The second control program 621 corresponds to an example of a "program." In this embodiment, the second control program 621 functions as application software, and therefore, in the following description, the second control program 621 may be referred to as "software."

[0036] The second version storage unit 622 stores second version information VE2. The second version information VE2 is version information of the second control program 621 installed in the display control device 60. Furthermore, every time the second control program 621 is installed in the display control device 60, the second version information VE2 stored in the second version storage unit 622 is updated.

[0037] The first acquisition unit 611 acquires first version information VE1 when the display control device 60 is communicatively connected to the main body control device 50. The first version information VE1 is version information of firmware 531 of the first communication interface 53 that communicates with the display control device 60 in the main body control device 50.

[0038] The second acquisition unit 612 acquires the second version information VE2 by reading out the second version information VE2 from the second version storage unit 622. The second version information VE2 is version information of the second control program 621 that is installed in the display control device 60 and displays the operating status of the tensile testing machine 1.

[0039] The display control unit 613 causes the display mechanism 64 to display various images. The display control unit 613 causes the display mechanism 64 to display notification information for the user based on, for example, the first version information VE1 and the second version information VE2. For example, when the second control program 621 is older than the firmware 531, the display control unit 613 displays first notification information MJ1 notifying that there are items that cannot be displayed on the display mechanism 64. Furthermore, when the firmware 531 is older than the second control program 621, the display control unit 613 displays second notification information MJ2 notifying that there are items that cannot be selected among the items displayed on the display mechanism 64. The display control unit 613 will be further described with reference to FIGS.

[0040] [4. Display item setting screen] Next, the display item setting screen 700 and the display item setting screen 800 will be described with reference to FIGS. 3 is a screen diagram showing an example of a display item setting screen 700. The display item setting screen 700 is displayed on the display mechanism 64 by the display control unit 613 when the second control program 621 is older than the firmware 531. The display item setting screen 700 corresponds to an example of the first notification information MJ1.

[0041] The display item setting screen 700 includes an SG extensometer display section 710 , a non-contact extensometer display section 720 , a recorder display section 730 , a chuck controller display section 740 , and a shatterproof cover display section 750 . The SG extensometer display unit 710 displays items related to the strain gauge type extensometer PA1. The non-contact extensometer display unit 720 displays items related to the non-contact extensometer PA2. The recorder display unit 730 displays items related to the recorder PA3. The chuck controller display unit 740 displays items related to the chuck controller PA4. The shatterproof cover display unit 750 displays items related to the shatterproof cover interlock PA7.

[0042] Check input sections M1 to M5 are displayed on each of the SG extensometer display section 710, non-contact extensometer display section 720, recorder display section 730, chuck controller display section 740, and shatterproof cover display section 750. For example, check input section M1 is checked by the user when displaying items related to the SG extensometer display section 710. Also, for example, check input section M2 is checked by the user when displaying items related to the non-contact extensometer PA2.

[0043] In FIG. 3, for example, the firmware 531 is the latest version, and the second control program 621 is an older version than the firmware 531. On the other hand, because the firmware 531 is the latest version, the main body control device 50 is configured to be able to connect the following optional devices PA: a strain gauge type extensometer PA1, a non-contact extensometer PA2, a recorder PA3, a chuck controller PA4, a marker controller PA5, a crosshead movement detection encoder PA6, and a shatterproof cover interlock PA7. In other words, the main body control device 50 can transmit information about each of the strain gauge type extensometer PA1 to the shatterproof cover interlock PA7 to the display control device 60 via the first communication interface 53.

[0044] On the other hand, since the second control program 621 is an older version than the firmware 531, for example, as shown in FIG. 3, the display item setting screen 700 does not display items related to the marker controller PA5 and items related to the crosshead movement amount detection encoder PA6.

[0045] By visually checking the display item setting screen 700, the user can confirm that the items related to the marker controller PA5 and the items related to the crosshead movement amount detection encoder PA6 are not displayed.

[0046] Furthermore, for example, when the second control program 621 is older than the firmware 531, the display control unit 613 may display a first message indicating that there are items that cannot be displayed on the display mechanism 64 as first notification information MJ1 on the display mechanism 64. The first message may be, for example, "The control program installed in the display control device is an older version than the firmware of the main body control device, so there are items that cannot be displayed." By visually checking the first message, the user can confirm that the second control program 621 installed in the display control device 60 is an older version than the firmware 531 of the main body control device 50.

[0047] 4 is a screen diagram showing another example of the display item setting screen 800. The display item setting screen 800 is displayed on the display mechanism 64 by the display control unit 613 when the firmware 531 is older than the second control program 621. The display item setting screen 800 corresponds to an example of the second notification information MJ2.

[0048] The display item setting screen 800 includes an SG extensometer display section 810, a non-contact extensometer display section 820, a recorder display section 830, a chuck controller display section 840, a marker controller display section 850, a crosshead encoder display section 860, and a shatterproof cover display section 870. The SG extensometer display unit 810 displays items related to the strain gauge type extensometer PA1. The non-contact extensometer display unit 820 displays items related to the non-contact extensometer PA2. The recorder display unit 830 displays items related to the recorder PA3. The chuck controller display unit 840 displays items related to the chuck controller PA4. The marker controller display unit 850 displays items related to the marker controller PA5. The crosshead encoder display unit 860 displays items related to the crosshead movement amount detection encoder PA6. The shatterproof cover display unit 870 displays items related to the shatterproof cover interlock PA7.

[0049] Check input sections M1 to M7 are displayed on each of the SG extensometer display section 810, non-contact extensometer display section 820, recorder display section 830, chuck controller display section 840, marker controller display section 850, crosshead encoder display section 860, and shatterproof cover display section 870. For example, check input section M1 is checked by the user when displaying items related to the SG extensometer display section 710. Also, for example, check input section M2 is checked by the user when displaying items related to the non-contact extensometer PA2.

[0050] In FIG. 4, for example, the second control program 621 is the latest version, and the firmware 531 is an older version than the second control program 621. On the other hand, since the second control program 621 is the latest version, the display control device 60 can display information regarding each of the strain gauge extensometer PA1, the non-contact extensometer PA2, the recorder PA3, the chuck controller PA4, the marker controller PA5, the crosshead movement detection encoder PA6, and the shatterproof cover interlock PA7.

[0051] On the other hand, because the firmware 531 is an older version than the second control program 621, it cannot transmit, for example, information about the marker controller PA5 and the crosshead movement amount detection encoder PA6 to the display control device 60. Therefore, for example, a check input operation is not accepted in the check input section M5 of the marker controller display section 850 and the check input section M6 of the crosshead encoder display section 860 displayed on the display item setting screen 800. In other words, the user cannot select the check input section M5 and the check input section M6.

[0052] By operating the display item setting screen 800, the user can confirm that the items related to the marker controller PA5 and the items related to the crosshead movement amount detection encoder PA6 are not selected.

[0053] Furthermore, for example, when the firmware 531 is older than the second control program 621, the display control unit 613 may display a second message indicating that there are items that cannot be selected on the display mechanism 64 as second notification information MJ2 on the display mechanism 64. The second message may be, for example, "The firmware of the main body control device is an older version than the control program installed in the display control device, so there are items that cannot be selected." By visually checking the second message, the user can confirm that the firmware 531 of the main body control device 50 is an older version than the second control program 621 installed in the display control device 60.

[0054] [5. Display Control Device Processing] Next, the processing executed by the display control device 60 will be described with reference to FIG. FIG. 5 is a flowchart showing an example of processing by the display control device 60. As shown in FIG. 5, first, in step S101, the display control device 60 determines whether or not it is connected to the main body control device 50 so as to be able to communicate with it. If the display control device 60 determines that it is not connected to the main body control device 50 so as to be able to communicate (step S101; NO), the process goes to a standby state. If the display control device 60 determines that it is connected to the main body control device 50 so as to be able to communicate (step S101; YES), the process proceeds to step S103. Then, in step S103, the first acquisition section 611 acquires the first version information VE1 from the main body control device 50. The first version information VE1 is version information of the firmware 531 installed in the first communication interface 53. Next, in step S105, the second acquisition unit 612 acquires the second version information VE2 by reading the second version information VE2 from the second version storage unit 622. The second version information VE2 is version information of the second control program 621 installed in the display control device 60.

[0055] In step S107, the display control unit 613 determines whether the second control program 621 is older than the firmware 531, for example, based on the first version information VE1 and the second version information VE2. If the display control unit 613 determines that the second control program 621 is older than the firmware 531 (step S107; YES), the process proceeds to step S109. Then, in step S109, the display control unit 613 displays first notification information MJ1 notifying that there is an item that cannot be displayed on the display mechanism 64. For example, the display control unit 613 displays a first message as the first notification information MJ1. Thereafter, the process proceeds to step S115. If the display control unit 613 determines that the second control program 621 is not older than the firmware 531 (step S107; NO), the process proceeds to step S111.

[0056] Then, in step S111, the display control unit 613 determines whether the firmware 531 is older than the second control program 621. If the display control unit 613 determines that the firmware 531 is older than the second control program 621 (step S111; YES), the process proceeds to step S113. Then, in step S113, the display control unit 613 displays the second message as the second notification information MJ2, after which the process proceeds to step S115.

[0057] If the display control unit 613 determines that the firmware 531 is not older than the second control program 621 (step S111; NO), the process proceeds to step S115. Then, in step S115, the display control unit 613 displays the display item setting screen 700 or the display item setting screen 800, and receives the selection of a display item from the user, after which the process ends.

Therefore, the user can select whether or not to display the items related to each of the plurality of optional devices on the display mechanism, thereby improving user convenience.

[0067] (Section 5) The display control device of this embodiment is a display control device that has a display mechanism and is communicatively connected to a main body control device that causes the testing machine main body of a materials testing machine to perform material tests.When communicatively connected to the main body control device, the display control device is equipped with a first acquisition unit that acquires first version information, which is version information of the firmware of the communication interface that communicates with the display control device in the main body control device, a second acquisition unit that acquires second version information, which is version information of a program installed in the display control device and displays the operating status of the materials testing machine, and a display control unit that displays whether or not there are any items that cannot be displayed based on the first version information and the second version information.

[0068] According to the display control device described in paragraph 5, when the display control device is connected to the main body control device so that it can communicate with the device, the display mechanism is caused to display whether or not there are any items that cannot be displayed based on the first version information and the second version information. Therefore, the user can visually check whether there are any items that cannot be displayed on the display mechanism, and therefore appropriate information can be provided to the user, resulting in improved user convenience.

[0069] [7. Other embodiments] The tensile testing machine 1 according to this embodiment is merely an example of an embodiment of a material testing machine according to the present invention, and can be modified and applied as desired within the scope of the present invention.

[0070] For example, in this embodiment, a case will be described in which the material testing machine is a tensile testing machine 1, but this is not limiting. The material testing machine may apply a test force to the test piece TP and deform the test piece TP to perform a material test. For example, the material testing machine may be a compression testing machine, a bending testing machine, or a torsion testing machine.

[0071] 2 indicates a functional configuration, and the specific implementation form is not particularly limited. In other words, it is not necessary to implement hardware corresponding to each functional unit individually, and it is of course possible to implement a configuration in which a single processor executes a program to realize the functions of multiple functional units. Furthermore, some of the functions realized by software in the above embodiments may be realized by hardware, or some of the functions realized by hardware may be realized by software.
