BEST MODE FOR CARRYING OUT THE INVENTION A material testing machine according to an embodiment of the present invention will be described below with reference to the drawings.
The input form of the control command from the data processing device 30 for the execution of the material test in No. 0 will be described. The material testing machine according to this embodiment is basically the testing machine body 10 and the dynamometer 20 for controlling the operation of the testing machine body 10 as described with reference to FIG. Control command, and collects measurement data consisting of the load and displacement of the specimen measured via the dynamometer 20 to obtain the load / elongation characteristics and display them in a graph. And a data processing device 30 for obtaining material characteristics such as rate.

The information input means according to this embodiment is characterized by setting a plurality of function buttons (icons, etc.) 41 on the display 31 of the data processing device 30 as shown in FIG. The operation screen 42 is displayed and the function button 41 on the operation screen 42 is assigned to the specified function button 41 by selectively designating the function button 41 via the input unit 32 including a pointer device such as a mouse. The test status monitoring means 4 for monitoring the execution status of the material test carried out in the tester body 10 in particular.
3 and the display form of the function button 41 on the operation screen 42 according to the monitored test situation, for example, the display color is changed to indicate the progress status of the test, or the control command assigned to the function button 41 is changed. In addition, the display mode control means 44 for changing the function button 41 to be selectively displayed is provided.

The function button 41 by this button function setting means 45
The change of the assignment of the control command of, for example, divides the test execution state in the tester main body 10 into a plurality of stages in advance, and assigns a control command function (role) to each of the plurality of function buttons 41 in advance according to each stage. Set it. Then, these function buttons 41 are displayed in an overlapping manner so that the function buttons 41 are selectively displayed, or each function button 41 is controlled to be displayed or hidden. Further, the control command generating means 46 which detects a selective instruction of the function button 41 by the input section 32 and issues a control command outputs the control command assigned to the function button 41 in accordance with the test situation. Has become.

The material test execution control by the data processing device 30 having the test status monitoring means 43, the display mode control means 44, and the button function setting means 45 will be described in detail. 31
Then, a control screen as shown in FIG. 3, for example, is displayed and executed. This control screen consists of a graph display field for displaying measurement data in a graph and a control condition display field for displaying control conditions for the test.
An operation screen 42 (operation field) for inputting various control commands is provided in a part of this control screen.

On the operation screen 42, however, the function buttons 41 which are independent of each area divided in advance are provided.
When the partitioned area is selectively designated by using, for example, a mouse pointer, the function (control command) assigned to the area is interpreted as being selectively designated. Incidentally, the selection instruction of the function button 41 is detected from the relationship between the coordinates on the display 31 which are actually instructed using the mouse pointer and the display position of the function button 41 displayed as each of the divided areas. It

Incidentally, the function (control command) of the function button 41 assigned to each area is presented to the operator by the control command name displayed on the divided area. The function button 41 assigned to each area is changed according to the implementation status of the test monitored by the test status monitoring means 43. In particular, the function (control command) to be assigned to each area forming the function button 41 is changed under the control of the button function setting means 45, for example, a plurality of function buttons 41 displayed in an overlapping manner.
This is performed by designating the function button 41 to be selectively displayed by designating the function button 41 to be displayed at the uppermost position, and validating only the function assigned to this function button 41.
The function itself associated with the function button 41 may be changed and the function name displayed on the function button 41 may be rewritten.

On the other hand, for the specific function button 41, for example, the marker area 4 for status display is located at the left corner of the partition area.
1a is provided, and by making the marker area 41a a specific display color, the implementation status of the test, particularly the progress status thereof, is presented. Specifically, when a function button 41 is selectively designated and a control command assigned to the function button 41 is being executed, the function button 4 is
The first marker area 41a is turned on (display driven) in a specific display color, and the fact that the command is being executed is displayed. Further, such a display of the marker area 41a prompts the user to select and specify the function button 41 provided with the marker area 41a.

The child screen 49 shown on the side of the control screen in FIG. 3 is opened by, for example, selecting and designating the function button 41 of "scale change" on the operation screen 42. For example, when the measurement data is displayed as a graph in the graph display field, change control of the display scale is performed. Such a child screen 49 is opened appropriately under the instruction of the operator regardless of the test implementation status.

The change of the function (control command) of the function button 41 assigned to the display area (section area) of the plurality of preset function buttons 41 on the operation screen 42 will be specifically described below. In the initial state of starting the material testing machine, for example, as shown in FIG.
An operation screen 42 as shown in (a) is displayed. The operation screen 42 is in a state in which a control command name is not displayed in each divided area, that is, a plurality of divided areas for realizing the function button 41 are set, that is, blank. Such an empty operation screen 42
The display indicates that the current test implementation status is in the initial state, particularly when the test conditions are being read from a file that stores preset test conditions. In this case, as a matter of course, the function button 41
The selection instruction for is ignored.

When the reading of the test conditions is completed, or when the previously executed previous test data is confirmed, the respective function buttons 41 as shown in FIG. The control command name is displayed in each of the divided areas and the contents of the operation screen 42 are changed. Specifically, according to the read test conditions, as shown in FIG. 4 (b), a plurality of function buttons 41 are given a [condition transmission] [test result]
The control function of each function button 41 is set by giving a control command name of [Hold] [Distortion meter removal] [Return] [End]. When the test conditions are such that they are executed in lot units, they are functionally the same, but instead of the control command name of [End], in order to end the test execution in the middle of the lot. Alternatively, a control command name such as [lot cancellation] whose concept is easy to understand may be displayed. That is, in this case, the specific function button 41 is
Selectively set the control function of [Lot Cancel] or [End]. In addition, when the strain gauge is not used, the above-mentioned [remove strain gauge] control function is not set. Therefore, this partitioned area remains blank.

Therefore, the operation screen 42 described above
When the function button 41 called "condition transmission" is selected and given its control command, and the execution of the test condition is started by this, as shown in FIG. The function of the function button 41, which had been given the following control function, was changed to [Test start], and also [Lot stop] or [End]
The function of the control button 41 which was given the control function of [Stop]
Is changed to. Then, a stop command is given to the conditional transmission using the function button 41 to which the function of [stop] is assigned. The operation screen 42 shown in FIG. 4C is continuously displayed until the control button 41 to which the function of “test start” is assigned is instructed to be selected, whereby the operation screen 42 is in a standby state before the start of the test. Is presented.

In this state, when an instruction such as "change scale" is given and the test condition is corrected, the operation screen 42 as shown in FIG. 4B is returned again. If the condition transmission has already been completed when the function button 41 to which [Stop] is assigned is selected, for example, by clicking the function button 41, the above-mentioned FIG.
The state of the operation screen 42 as shown in, that is, 1
The process of returning to the operating state before the step is performed.

On the other hand, when [Test start] is selected and instructed on the operation screen 42 shown in FIG. 4 (c), a control command for starting the test is given by this, and the material test of the test piece in the tester main body 10 is performed as described above. Started under test conditions. At the same time, on the operation screen 42, as shown in FIG. 5A, a color marker is displayed in the marker area 41a of the function button 41 to which the control function of [test start] is assigned, which indicates that the test is being executed. Is displayed. At this time, since the control command function of [Stop] is assigned to the function button 41 as it is, the stop command is promptly issued to the test being performed by selecting the function button 41. As a result, it is possible to easily and surely give an instruction for prevention of danger caused by an unexpected situation.

During the execution of this test, the above-mentioned test status monitoring means 43 monitors whether or not the conditions for ending the test are satisfied. That is, during execution of the material test, it is monitored whether, for example, a stop command is given, the test piece is broken, and whether or not an abnormality (fault status) of the cooling pump or the like occurs in the tester body 10. ing. When the failure status is detected, the state shifts to a data confirmation waiting state described later. Then, on the operation confirmation screen 42 waiting for data confirmation, a selection instruction for saving or canceling the measurement data obtained so far is waited.

When the test completion condition is satisfied as the test is carried out, the operation screen 42 is updated as shown in FIG. 5B. This operation screen 42 is in a state of waiting for a return, and by driving the marker area 41a of the function button 41 provided with a control function of [return] to light, an instruction of a return command is prompted. By selecting and instructing the function button 41 in this state, a return command is given to the dynamometer 20, and the marker area is displayed as shown in FIG. The display form of 41a is changed, and it is displayed that return is in progress. The return operation is an operation of returning the above-described load device 11 to the initial state and releasing the load state of the test piece. For example, a message such as "Returning to ram" is displayed in the guidance display area of the control screen. Is displayed.

When the return of the tester main body 10 is completed under the return command, the operation screen 42 displays the function button 41 to which the above-mentioned [condition transmission] control function is assigned, as shown in FIG. 5D, for example. Change to the control function called [Data input]. In addition, the function button 41 of [Test start] is changed to [Test result], [Hold] is [Data confirmed], [Strain gauge removal] is [Data cancel], and [Stop] is set.
Change the function to [Lot Cancel]. That is, when the test for one specimen is completed, it is not necessary to stop the test. For example, whether to stop the continuous test for the lot, and further to confirm the measurement data obtained by the above test. Since it is necessary to select whether or not (measured) the measured data should be taken into (stored in) a file (cancel), the control function of the function button 41 is changed as described above. As a result, only the instruction for selecting the control command required at that time is prompted.

However, such an operation screen 4
2 is instructed to process the measurement data, the operation screen 42 changes the function of each function button 41 as shown in FIG. The condition is returned to the state of waiting for transmission, or the state of waiting for the test as shown in FIG. 4C, and execution of the test for the next sample is prompted.

Thus, according to the material testing machine configured as described above, the operation screen 42 is displayed on the display 31 of the data processing device 30, and the plurality of function buttons 41 set on the operation screen 42 are selected and instructed to be selected. However, when inputting the control command assigned to the function button 41, the control command function assigned to the predetermined number of function buttons 41 set on the operation screen 42 of a limited size is changed to the test implementation status. Since it is changed accordingly, it is possible to easily and accurately input the control command according to the implementation status of the test. Moreover, it is possible to understand the test implementation status from the function name assigned to the function button 41. In particular, by controlling the display form shown by using the marker area 41a, it is possible to present the test implementation status in more detail, so that the status can be more accurately grasped.

In particular, according to the above-described function of changing the function button 41 according to the test status, control commands such as [abort lot] and [end], which were necessary when transmitting the test conditions, are unnecessary after the test is started. Therefore, the function button 41 to which the control command such as [abort lot] or [end] is assigned is hidden, and the function button 41 to which the control command function of [stop] is assigned is displayed instead. Therefore, it is possible to promptly, easily, and accurately instruct an emergency stop or the like during the execution of the test. In other words, many function buttons 4
Even if the user does not search for the [stop] function button 41 from among 1, the limited number of function buttons 41 displayed on the operation screen 42
It is possible to easily find the function button 41 to which the control command function to be instructed is assigned from among the above.

Rather, only the control commands that need to be input, which are specified by the execution status of the test, are assigned to the function buttons 41. Therefore, it is possible to simply control by simply instructing the function buttons 41 to which these control commands are assigned. It can give commands and its operability is very good. Therefore, there is no possibility of giving an unintentional control command, and it is possible to achieve a great practical effect such that an accurate control command can be given.

The present invention is not limited to the above embodiment. For example, the configuration of the operation screen 42 and the function buttons 41 to be prepared on the operation screen 42
The number and the size thereof may be determined according to the specifications of the data processing device 30. Further, instead of providing the marker area 41a, it is possible to change the display form of the entire partitioned area forming the function button 41. The above-mentioned information input means may be realized on the display of the personal computer which is the main body of the data processing device, or it may be realized using the display of the dynamometer. When realizing with a dynamometer, for example, a pointer device such as a transparent touch panel may be incorporated on the display. In addition, the present invention can be variously modified and implemented without departing from the scope of the invention.

[0033]

As described above, according to the present invention, the control command function assigned to a plurality of function buttons preset on the operation screen is adaptively changed and controlled according to the implementation status of the material test. By effectively utilizing a limited number of function buttons, it is possible to easily and accurately input a control command according to the test implementation status. Moreover, as described above, it is possible to effectively grasp the execution status of the test from the status of the function button whose control command function is changed.
