Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a material tester, and more particularly to an apparatus for checking various data input for setting initial conditions, test conditions, and the like in the material tester.

[0002]

2. Description of the Related Art Conventionally, various material testers have been known as devices for measuring and evaluating physical characteristics or chemical characteristics of materials. For example, a hardness tester is made of metal materials,
Non-metallic materials such as plastic, rubber, ceramic, etc.
It is a material tester for evaluating the surface strength of various materials, and is also used for measuring the hardness of thin films and surface treatment layers.

[0003] In such a hardness tester, various tests such as an indenter indentation test, a load / unload test, a repetitive test for a soft material, an indentation depth setting test, a step load test, and a step load / unload tester are used. In order to perform the above test, it is necessary to set initial conditions and test conditions.

When setting various data of such initial conditions and test conditions in a material tester, it is necessary to confirm whether or not the input data satisfies predetermined conditions. For example, it is necessary to check whether the set value of the test load satisfies the allowable value of the tester, whether the set constant is within the range permitted by the tester, and the like.

Conventionally, in checking data in such a condition setting, after input of all data is completed, input data values are checked collectively, or when input of one item is completed, , Check the data value.

[0006]

In the conventional material tester, if all input data values are checked at once after inputting all data, there is a problem in operability of data correction. There is. For example, if there are many errors in data entry, all errors are displayed at once to check them all at once. When the error display mode and the data correction mode are different, the operator needs to memorize the item indicated by the error in order to correct erroneous input data. In addition, when performing error checking in a lump, in the mode in which errors are displayed for each item and data is corrected, if many errors occur, it is difficult to grasp the entire error. There is.

Further, when input data is checked for each item, data input and input data check are always integrated processes. Therefore, when input processing is completed during data input, However, there is a problem in that data check processing is performed on the data input in step (1) even though the data check is unnecessary.

Accordingly, an object of the present invention is to solve the above-mentioned problems of the conventional material tester, to provide a material tester in which input data can be easily corrected for errors, and to check input data. It is an object of the present invention to provide a material tester that can execute a data check process only in such a case.

[0009]

The material tester of the present invention comprises:
In setting the measurement conditions required for material testing, when determining whether or not the input data satisfies the input conditions, automatically read the pre-stored check contents according to the setting items. This is to judge the data conformity with the data, and to judge the conformity of the data input to the setting item when the setting item is changed, thereby checking the data only when it is necessary to check the input data. Can be executed.

In order to perform the above data check, a material tester according to the present invention is a material tester comprising: a tester main body; and a measurement control device for controlling the tester main body and performing a material test. Is provided with data confirmation means for confirming input data of the measurement conditions of the material test, and the data confirmation means includes a check content for determining the conformity of the input data;
A data storage unit that stores the error recovery processing content at the time of non-conformity and setting data as a storage content, a check execution unit that determines whether or not the input data conforms according to the read check content, and a read error recovery process content. An error recovery unit for performing error processing and a data setting unit for setting suitable input data are provided. When the item of the input data is changed, the check execution unit stores the check contents corresponding to the item before the change in the data storage unit. , And determines whether or not the input data is appropriate based on the contents of the check.

According to the material tester of the present invention, after the data is input to one item, if the item for which data is to be input is changed, the check execution unit changes to the previous item at the timing of this change. The contents of the check for performing the corresponding suitability determination are read, and the suitability of the input data is determined based on the check contents. If the input data satisfies the check, the input data is stored in the data storage unit as setting data. On the other hand, when the input data does not satisfy the check content, the error recovery processing content is read from the error recovery unit, and the input data error recovery is performed based on this processing content.

Thus, the point in time at which the data input item is changed is regarded as the time when the input data needs to be checked, and the data check process is executed only at this time. As a result, if the input processing is canceled at the time when the data is input, the input data is not checked at this time, so that unnecessary data check can be omitted.

According to a first embodiment of the present invention, when stored data is stored in a check content portion of a data storage unit, a check is made by the check execution unit to determine whether or not the input data is compatible. In the case where the stored data is not stored in the part of the above, the conformity determination of the input data by the check execution unit is not performed.
Only when the input data needs to be checked, the data check process can be executed. According to the second embodiment of the present invention, the check contents of the data storage unit can be set by a function using other setting data as a parameter,
It is possible to set a determination condition having a wide applicability.

In the third embodiment of the present invention, items for inputting data can include initial conditions and test conditions, and initial conditions and test conditions corresponding to each material test can be set. it can.

[0015]

Embodiments of the present invention will be described below in detail with reference to the drawings. A configuration example of an embodiment of the present invention will be described with reference to a schematic block diagram for explaining a material tester of the present invention in FIG. In FIG. 1, a material tester 1 includes a tester main body 2 and a measurement control device 3.
, A display control device 5, an input device 6, and a display device 7.

The material tester 1 of the present invention can be applied to various devices for measuring and evaluating physical characteristics or chemical characteristics of various materials, but the following configuration is an example. This will be described using a hardness tester.

The tester main body 2 is movable in the X, Y, and Z directions, and is capable of adjusting the observation position of a placed sample, and a probe such as an indenter on the sample on the sample stage 21. A load unit 22 for applying a load such as pressure by pressing the sample, a measuring unit 23 for measuring the deformation of the sample, and an optical system 24 for optically observing the state of the sample.

The measurement control device 3 includes the sample stage 2
1, a control unit 31 that controls the load unit 22, the measurement unit 23, and the optical system 24; a measurement unit 32 that inputs signals from the measurement unit 23 and the optical system 24 to perform measurement; A condition input unit 33 for setting various conditions such as initial conditions and measurement conditions for the unit 32; Condition input section 3
Input of data to the device 3 is performed by the input device 6 installed outside through the I / O 34. The material tester of the present invention includes the data confirmation unit 4 for determining the appropriateness of the data input to the condition input unit 33.

The data confirmation means 4 includes a data storage section 41 for storing various data, and a data storage section 41 for storing the data.
A data setting unit 42 for setting data in the memory and performing data storage; a check execution unit 43 for checking input data; and an error recovery unit 44 for performing error recovery when input data is inappropriate. . Data storage unit 41
Is a setting data storage unit 41a for storing the setting data by the data setting unit 42, a check content storage unit 41b for storing the data check content in the check execution unit 43, and an error for storing the recovery content in the error recovery unit 44. A recovery storage unit 41c is connected to the data setting unit 42, the check execution unit 43, and the error recovery unit 44, and the data setting unit 42 is connected to the condition input unit 33. The setting state of the input data can be displayed on the display device 7.

Although the configuration example shown in FIG. 1 shows an example in which the setting data storage unit 41a, the check content storage unit 41b, and the error recovery storage unit 41c are configured by independent storage units, a single storage unit is used. It is also possible to adopt a configuration in which the storage area of the single storage section is divided using the storage section.

The hardness tester can perform various tests such as an indenter indentation test, a load / unload test, a repetitive test for a soft material, a push depth setting test, a step load test, and a step load / unload tester. To perform the test,
Set initial conditions and test conditions. FIG. 2 is a display example of the initial condition setting, and shows a case where the initial condition in the pushing depth setting test is set. 2, terms of the type of indenter (number 1 in FIG. 2), terms of spring constant of the cantilever (number 2 in FIG. 2), and terms of the R value at the tip of the indenter (FIG. It is confirmed whether or not to perform the setting process based on the numeral 3), the item of the load unit (the numeral 4 in FIG. 2), the item of the indentation depth unit (the numeral 5 in FIG. 2), and the set value on the initial condition screen. The term “OK” (numeral 6 in FIG. 2) and the term “cancel” (numeral 7 in FIG. 2) are shown as examples.

Next, the contents stored in the data storage unit 3 in the above-mentioned initial condition setting will be described with reference to FIG. FIG. 3A shows an example of storage contents of setting data, and FIG. 3B shows an example of storage contents of check contents.
FIG. 3C shows an example of the stored contents of the error recovery check contents.

In FIG. 3A, for each of the items A and B of the setting data, the input states for new settings are stored in states a and b, and the current setting states that have already been set are stored in states A and B. Stored in state B for storage contents. For example, when a triangle cone indenter has already been set and a new Vickers indenter is to be set, in the indenter item, the storage content of the set state is a triangle cone indenter, and the storage content of the input state is a Vickers indenter. When a load unit of μN has already been set and a new load unit of nN is set, the stored content of the set state is “N” and the stored content of the input state is “nN” in the item of the load unit.

In FIG. 3B, for each of the items A and B of the check contents, the processing contents to be performed by the check execution section are set as contents a and b. For example, in the item of the spring constant of the cantilever, “real value of 0 or more” is set as the check content. Thus, when a numerical value is input to the term of the spring constant of the cantilever, the appropriateness of the data is determined depending on whether or not the input value is a real numerical value of 0 or more.

In some cases, such as the item of the load unit, it is not necessary to set the check content depending on the item, and the check content is not stored in the item. If the content is not set in this setting item, the data setting process can be speeded up by moving to the next setting item without performing a check process on the item.

In FIG. 3C, for each of the items A and B of the error recovery method, the processing contents to be performed by the error recovery unit are set to methods A and B. For example, in the item of the spring constant of the cantilever, “return to the set state” is set as the error recovery method. In this way, if it is determined in the check performed by the check execution unit that the value is inappropriate, the setting of the item of the spring constant of the cantilever is returned to the original setting state, and the state is set to be reset.

In some cases, like the item of the load unit, the error recovery method is not required for some items as in the case of the setting of the check content, and the error recovery method is not stored in the item. In this case, since no setting has been made for the check content, no check processing is performed, and no reading of the error recovery method is performed.

Next, the operation of the material tester of the present invention will be described with reference to the flowchart of FIG. On the initial condition setting screen of FIG. 2, the item currently being set can be displayed as a display state different from other items by color display, blinking display, or the like. The data setting section can read that this item is being set by different status displays. Hereinafter, a portion for inputting a setting for an item will be referred to as a control. Here, the data setting unit 42 of the data confirmation unit 4 acquires the control being input from the condition input unit 33 and starts the data confirmation processing (step S1).

The data setting section 42 stores the input set value obtained by the obtained control in the input state area of the data storage section 41a. At this time, the data that has already been set is not changed and the data storage unit 41
The data is kept stored in the setting state area a (step S2).

The check execution unit 43 monitors the movement of the control indicating the item being set on the condition setting screen, and determines whether or not the control has been moved (step S3). If the control does not move, the process returns to step S1 and waits until the next control is input. When the control is moved, the check execution unit 43 reads the check content corresponding to the item being set from the check content area of the check content storage unit 41b (step S4). The check execution unit 43 determines that the check is necessary when the check content is written in the check content area of the check content storage unit 41b, and when the check content is not written, It is determined that the check is unnecessary (step S5). If the check is unnecessary, in step S12, the contents of the input state area of the data storage section 41a are cleared, and the input of the next data is awaited.

If a check is required in step S5, the check execution section 43 sets the setting data storage section 41
The input setting value stored in the input state area a is fetched (step S6), and the input setting value fetched is judged as appropriate in accordance with the contents of the check (step S7).

If the result of the check determination (step S8) indicates that the input set value is not appropriate, the check execution unit 43
Reads the error recovery method corresponding to the setting item from the error recovery storage unit 41c (step S9), and performs input data recovery processing according to the error recovery method. As an example of the recovery method, a process of returning to the state value before the input can be set (step S10).

If it is determined in step S8 that the set value is appropriate, the data setting section 42 writes the data in the input state area into the set state area of the setting data storage section 41a to update the stored contents. Later (Step S1
1) The contents of the input state area of the data storage unit 41a are cleared (step S12), and the setting process for one item is terminated (step S13).

Next, another configuration of the stored data will be described with reference to FIGS. FIG. 5 is a diagram for explaining another configuration example of the storage data in the setting data storage unit. In the example shown in FIG. 3, the setting data, the check content, and the error recovery method are stored in different areas. On the other hand, in the example of FIG. 5, the setting data, the check content, By setting an error recovery method, the data is stored in one storage area.

FIG. 6 shows a configuration example in which the input state is set as an independent setting item. In FIG. 6, when the input state is set for one item of the stored data and each item of item A, item B,... Is set, the state In is stored in the item of the input state in step S2. The data setting process is performed using the state In. Thus, in the configuration examples shown in FIGS. 3 and 5, the storage area of the input state required for each item is set as one area, and the required storage capacity can be reduced.

In the configuration example shown in FIG. 7, the contents of the initial conditions, test results, and functions can be set in the contents of the check of the stored data. For example, in FIG. 7, the check content Q, the initial condition M, and the test result of the test O are set as the check content of the items of the test condition Q. If these are the setting conditions, check contents Q
In addition to the contents set in, initial conditions M set in other items
And a test result O are read, and a check is performed using these as a determination condition.

The item of the test condition R is for setting a function R in the check contents, and an arithmetic function and a statistical function can be used as the function. Data and test results set in other items can be used as numerical values to be substituted into functions.

According to this embodiment, the data check process can be executed only when the input data needs to be checked.

According to the embodiment of the present invention, since other conditions, test results and functions can be set, comprehensive judgment conditions can be set.

According to the embodiment of the present invention, the initial condition and the test condition are included as the items for inputting the data.
Initial conditions and test conditions corresponding to each material test can be set.

[0041]

As described above, according to the material tester of the present invention, errors in input data can be easily corrected. The data check process can be executed only when the input data needs to be checked.
