Description

The present invention relates to measurement systems.

Conventionally, a measurement system comprising a measuring device that measures an object to be measured and acquires a measured value, an external device that acquires and processes information of the measuring device including the measured value, and a connection means that connects the measuring device and the external device. It has been known. The measuring instruments are, for example, vernier calipers, indicators, linear scales, micrometers, and the like.

In such a measurement system, since the measured values measured by the measuring device are processed by the external device, information from the measuring device including the measured value must be reliably transmitted from the measuring device to the external device. For example, in the measurement processing system (measurement system) disclosed in Patent Document 1, determination of whether or not information has been successfully transmitted is automated. Specifically, the measurement processing system is composed of a displacement measuring device (measuring device) and a data processing device (external device) located at a remote location. The displacement measuring device has a transmitting/receiving circuit, and the data processing device has a transmitting/receiving circuit corresponding to the transmitting/receiving circuit of the displacement measuring device, and performs two-way communication.

The displacement measuring device includes a length measuring sensor for measuring an object to be measured, a measuring circuit for obtaining measured data from the length measuring sensor, a display device for displaying the measured data, a data storage device for storing the measured data, and a data processor. and a retransmission determination circuit that determines whether or not to retransmit the measured data to the data processing device based on the signal of .
The data processing device includes an error detection circuit for detecting whether or not there is an error in the measurement data received from the displacement measurement device via the transmission/reception circuit, and an error detection circuit for notifying the displacement measurement device that the measurement data has been received normally. a transmission confirmation signal generation circuit for generating two types of signals, a transmission confirmation signal and a retransmission request signal for requesting retransmission of measurement data when there is an error in the measurement data.

When the retransmission determination circuit of the displacement measuring device receives the transmission confirmation signal from the data processing device, it determines that the measurement data has been successfully transmitted, and does not retransmit the measurement data. A retransmission determination circuit of the displacement measuring device retransmits the measurement data stored in the data storage device to the data processing device when a retransmission request signal is received from the data processing device. The retransmission determination circuit of the displacement measuring device receives a retransmission request signal instead of receiving a transmission confirmation signal when a transmission confirmation signal cannot be received from the data processing device, or even though measurement data has been retransmitted a predetermined number of times. If this occurs, it is determined that there is an abnormality (error), and a warning about the abnormality is displayed on the display device of the displacement measuring device.
Therefore, the measurement processing system automatically detects errors in the measurement data and, if necessary, resends the measurement data or displays a warning, thereby improving measurement efficiency and increasing the reliability of data transmission processing. can be improved.

JP-A-7-21486

However, in such a measurement processing system (measuring system), even if a warning is displayed on the display device of the displacement measuring device (measuring device), the user can continue to use the measuring device. At this time, continued use of a measuring system or measuring device with an error may cause an error in the measurement of the object to be measured or damage the measuring device or external device. Therefore, there is a problem that the reliability of the measurement system may deteriorate.

An embodiment of the present invention will be described below with reference to the drawings.
FIG. 1 is a schematic diagram showing a measurement system 1 according to one embodiment of the invention.
As shown in FIG. 1, the measurement system 1 includes a measuring device 2 that measures an object W to be measured and acquires measured values, an external device 3 that acquires and processes information about the measuring device 2 including the measured values, and the measuring device 2. and connection means 4 for connecting to the external device 3 .
The measuring instrument 2 is, for example, a vernier caliper. The measuring instrument 2 includes an elongated main scale 21 and a slider 22 slidably provided along the longitudinal direction of the main scale 21 .

The main scale 21 is formed in a substantially T-shape, and includes a main scale base 23 in the form of a rectangular plate, and measuring jaws 24A and 24B as measuring means 20 projecting from the main scale base 23 and brought into contact with an object to be measured for measurement. , is equipped with
The measuring jaws 24A and 24B are composed of an outer measuring jaw 24A formed on one longitudinal end side of the main scale base 23 and an inner measuring jaw 24B formed on the opposite side of the outer measuring jaw 24A.

The slider 22 includes measurement jaws 25A and 25B that are paired with measurement jaws 24A and 24B that project from the slider 22 and are brought into contact with the object to be measured for measurement, and a depth bar 26 that is the measurement means 20 used for depth measurement. , display means 5 provided in front of the measuring instrument 2 , and a leaf spring (not shown) provided between the main scale base 23 and adjusting the sliding force of the slider 22 .
The measuring jaws 25A and 25B are formed on one longitudinal end side of the slider 22 and pair with the outer measuring jaw 24A, and on the opposite side of the outer measuring jaw 25A and pairing with the inner measuring jaw 24B. and an inner measuring jaw 25B.

A depth bar 26 is provided on the other end side of the slider 22 .
The display means 5 displays information of the measuring equipment including measured values. Specifically, the display means displays the measurement result calculated by holding the object to be measured between the outer measurement jaws 24A and 25A or the inner measurement jaws 24B and 25B, the depth measurement result by the depth bar 26, and the like. The display means 5 displays information by using, for example, a plastic liquid crystal display as a flexible display. The display means 5 need not be a plastic liquid crystal display, and may be of any type as long as it can display the information of the measuring device including the measured values.

In FIG. 1, the measuring device 2 is measuring the object W by holding the object W to be measured between the outer measuring jaws 24A and 25A. The display means 5 displays measured values obtained by measuring the object W to be measured. In addition to the measured value, the display means 5 can display information related to the measuring device 2, such as the remaining amount of the battery used in the measuring device 2, the calibration time of the measuring device 2, and the date of manufacture of the measuring device 2. is.
The leaf spring adjusts the frictional force between the main scale base 23 and the slider 22 and adjusts the sliding force between the main scale 21 and the slider 22 .
Further, the measured values, which are the measurement results of the object W measured by the outer measuring jaws 24A and 25A and the inner measuring jaws 24B and 25B, and the depth bar 26, which are the measuring means 20, are output to the external device 3 via the connecting means 4. be done.

The external device 3 is, for example, a personal computer. Note that the external device 3 is not a personal computer but may be any device that can function as the external device 3 .
The connection means 4 connects the measuring device 2 and the external device 3 by wire, for example. The connecting means 4 may wirelessly connect the measuring device 2 and the external device 3 so as to enable communication via a network.

FIG. 2 is a block diagram showing the measurement system 1. As shown in FIG.
As shown in FIG. 2, the measuring instrument 2 includes measured value output means 6, information transmission means 7, error information reception means 80, output stop means 81, notification means 9, cancellation reception means 10, and output restart means. means 11;
The external device 3 includes information acquisition means 31, error detection means 32, error information transmission means 33, cancellation command transmission means 34, and cancellation command input means 12 for inputting a command to the cancellation command transmission means 34. .

The measured value output means 6 of the measuring device 2 outputs the obtained measured value. Specifically, the measured value output means 6 outputs to the display means 5 and the information transmission means 7 the measured value, which is the measurement result of the object W (see FIG. 1) measured by the measuring means 20 .
The information transmitting means 7 of the measuring device 2 transmits the information of the measuring device 2 to the external device 3 via the connecting means 4 . Specifically, the information transmitting means 7 transmits to the external device 3 via the connecting means 4 the measured value, which is the measurement result of the measurement object W measured by the measuring means 20 .

The information acquisition means 31 of the external device 3 acquires measured values from the information transmission means 7 of the measuring device 2 . The information transmitting means 7 may transmit other information to the external device 3 as long as it is information related to the measuring device 2 , such as the manufacturing date and calibration time of the measuring device 2 . Moreover, the information acquisition means 31 only needs to acquire the information transmitted from the information transmission means 7, and may acquire other information in addition to the measured values.

The error detection means 32 of the external device 3 detects the presence or absence of an error based on the measured value, which is the information of the measuring device acquired by the information acquisition means 31 . When an error is detected by the error detection means 32, the error information transmission means 33 transmits the error to the measuring instrument 2 as error information. Note that the error detection means 32 may detect the presence or absence of an error based on other information such as the date of manufacture and the time of calibration instead of the measured value.
The error information receiving means 80 of the measuring device 2 receives error information transmitted from the error information transmitting means 33 of the external device 3 via the connecting means 4 . The output stop means 81 of the measuring instrument 2 stops the output of the measured value by the measured value output means 6 based on the error information received by the error information receiving means 80 .

The output stop means 81 stops the output of the measured value by the measured value output means 6 to the display means 5 based on the error information. Further, the output stopping means 81 stops the output of the measured value by the measured value outputting means 6 to the information transmitting means 7 based on the error information. At this time, since the user only needs to be able to recognize that the output of the measured value by the measuring device 2 has been stopped, the measuring device 2 may continue the measurement and obtain a new measured value. In other words, it is not necessary to physically stop the measurement by the measuring device 2, and the output stop means 81 prevents the user from reading the measured value, which is the measurement result, via the display means 5 or the external device 3. This prevents the user from continuing the measurement using the measuring device 2 .
The notification means 9 displays the error information on the display means 5 in order to notify the error information. Note that the notification means 9 only needs to be able to notify the error information, so for example, an LED, a buzzer, or transmission of the error information to the portable terminal owned by the user may be used.

FIG. 3 is a flow chart showing a program used by the external device 3 in the measurement system 1. As shown in FIG.
A method of stopping measurement by the measuring device 2 will be described below with reference to FIGS. 2 and 3. FIG.
First, as shown in FIG. 3, the information acquiring means 31 of the external device 3 executes an information acquiring step of acquiring the measured value transmitted from the information transmitting means 7 of the measuring device 2 (step ST01). Next, the error detection means 32 of the external device 3 executes an error detection step of detecting the presence or absence of an error in the measuring device 2 based on the measured value, which is the information acquired in the information acquisition step (step ST02). Specifically, the error detection means 32 stores and stores the measured values from the measuring instrument 2, and the measured values stored in the storage means and the measured values acquired from the information transmitting means 7. A calculation means (not shown) for performing a predetermined calculation is provided, and the presence or absence of an error is detected based on a predetermined value from the calculation result of the calculation means. Then, the error detection means 32 detects an error in the measuring instrument 2 when the calculation result by the calculation means reaches a predetermined value.

When the error detection means 32 detects an error (YES in step ST03), the error information transmission means 33 of the external device 3 transmits the error as error information to the error information reception means 80 of the measuring device 2 via the connection means 4. An error information transmission step to be transmitted is executed (step ST04). When the error detection means 32 does not detect an error (NO in step ST03), the error detection means 32 executes the information acquisition step (step ST01) and the error detection steps (steps ST02 and ST03) until an error is detected.

FIG. 4 is a diagram showing the display of the display means 5 of the measuring instrument 2 in the measuring system 1. As shown in FIG. Specifically, FIG. 4A is a diagram showing the display of the display means 5 before the output of the measured value by the measured value output means 6 is stopped, and FIG. 2 is a diagram showing a display on the display means 5 after output of measured values by the measured value output means 6 is stopped by .
As shown in FIG. 4A, before the output of the measured value by the measured value output means 6 is stopped, the display means 5 displays the measured value W2 which is the measurement result of the measurement object W (see FIG. 1). is displayed. Therefore, the user can measure the object W to be measured by viewing the display means 5 . At this time, the measured value output means 6 outputs the measured value to the information transmitting means 7, and the information transmitting means 7 transmits the measured value to the external device 3. Measured value W2 is also displayed on the display means of .

However, as shown in FIG. 4B, when the output of the measured value by the measured value output means 6 is stopped by the output stop means 81 of the measuring instrument 2, the measured value to be displayed is not output. W2 is not displayed on the display means 5 of the measuring device 2 and the display means of the external device 3 . Then, instead of the measured value W2, an error display C is displayed as error information on the display means 5 of the measuring instrument 2 and notified. Therefore, the user cannot continue the measurement because the measured value W2 is not displayed on the display means 5 of the measuring device 2 or the display means of the external device 3, and the error display C is displayed on the display means 5. Since the error is displayed and notified, the measurement system 1 can reliably notify the user of the error.

After the measurement is stopped by the output stopping means 81 of the measuring device 2, the user operates the release command input means 12 provided in the external device 3 as shown in FIG. The stop of the output of is released, the output of the measured value by the measured value output means 6 is resumed, and the measurement can be restarted. The release command input means 12 is, for example, a predetermined button provided on the external device 3, a keyboard, a mouse, or the like. Note that the release command input means 12 may be of any type as long as it can input a release command for restarting the measurement.

If the measuring instrument 2 is provided with means for canceling the stoppage of the measured value output by the output stop means 81 and restarting the output of the measured value by the measured value output means 6, for example, a serious error occurs in the measuring system 1. However, the user can easily operate the measuring device to release the suspension of the output of the measured value and restart the output of the measured value to continue the measurement. It is provided only on the device 3 side.
Specifically, as shown in FIG. 2, the release command transmission means 34 of the external device 3 cancels the stoppage of the measured value output by the output stop means 81 input from the release command input means 12, and the measured value output means 6 is sent to the measuring instrument 2 to restart the output of the measured value. The cancellation acceptance means 10 of the measuring instrument 2 accepts the cancellation command, and the output restarting means 11 cancels the stoppage of the measured value output by the output stopping means 81 when receiving the cancellation command, and restarts the measured value outputting means 6. Resume output.

FIG. 5 is a flow chart showing a method of restarting the measurement of the measuring device 2 in the measuring system 1. FIG. A method for restarting the measurement of the measuring device 2 will be described below with reference to FIG.
As shown in FIG. 5, the external device 3 first executes an input determination step of determining whether or not a release command has been input from the release command input means 12 (step ST11). When the release command is input (YES in step ST12), the release command transmission means 34 executes a release command transmission step of transmitting the release command to the release reception means 10 of the measuring instrument 2 via the connection means 4 (step ST13). When the cancellation command has not been input (NO in step ST12), the input determination step is executed until the cancellation command is input (step ST11).
The release receiving means 10 of the measuring instrument 2 that has received the release command from the release command transmitting means 34 causes the output restarting means 11 to release the stoppage of the output of the measured value by the output stopping means 81 and the output of the measured value by the measured value output means 6. is executed (step ST14). As a result, the measured value W2 (see FIG. 4) is displayed on the display means 5 again, and transmission of the measured value to the external device 3 by the information transmitting means 7 is also restarted. Therefore, the user can resume the measurement stopped by the output stop means 81. FIG.

According to this embodiment, the following functions and effects can be obtained.
(1) The measuring device 2 includes an output stop means 81 for stopping output of measured values by the measured value output means 6 based on error information detected by the external device 3 . As a result, if there is an error, the measurement system 1 stops the output of the measured value by the measuring device 2 so that the measurement cannot be continued. can do. Therefore, the measurement system 1 can reliably notify the user of the error and suppress a decrease in reliability.
(2) The output stop means 81 stops the output of the measured value by the measured value output means 6 to the display means 5 based on the error information, and stops the output of the measured value by the measured value output means 6 to the information transmission means 7. Since the operation is stopped based on the information, it is possible to easily prevent the continuous use of the measuring device 2 by the user.

(3) The measuring device 2 is provided with the reporting means 9 for reporting error information, so that it is possible to notify the user that there is an error together with stopping the measurement by the measuring device 2 . Therefore, the measurement system 1 can reliably notify the user of the error.
(4) The notification means 9 notifies the user by displaying the error information on the display means 5, so that the user can be visually notified of the error. Therefore, the measurement system 1 can reliably notify the user of the error.

(5) Only the external device 3 side has a release command transmitting means 34 that transmits a release command to the measuring instrument 2 to release the suspension of the output of the measured value by the output suspending means 81 and restart the output of the measured value by the measured value output means 6. Therefore, the user cannot easily operate the measuring device to release the stoppage of the output of the measured value and restart the output of the measured value. Therefore, the measurement system 1 can suppress deterioration in reliability.
(6) An error detection step of detecting the presence or absence of an error in the measuring instrument 2 based on the information; and an error information transmission step of transmitting the error as error information to the measuring instrument 2 when an error is detected. The stopping means 81 can stop the measurement based on error information detected by the external device 3 . Therefore, if there is an error, the measurement system 1 can reliably notify the user of the error without requiring the user to continue the measurement, thereby improving reliability.

[Modification of Embodiment]
It should be noted that the present invention is not limited to the above-described embodiments, and includes modifications, improvements, etc. within the scope of achieving the object of the present invention.
For example, in the above embodiment, the measuring instrument 2 was a vernier caliper, but it may be a micrometer, a dial gauge, a test indicator, or the like. Moreover, the measuring device 2 is not particularly limited in terms of form, method, and the like.

In the above-described embodiment, the notification means 9 causes the display means 5 to display the error display C, but the notification means uses a speaker (buzzer), a light (light emitting device such as an LED), a vibrator, and notifies mail delivery by communication. Error information may be notified as a means. At this time, the notification means may notify by voice using a speaker, sound using a buzzer, blink or light an LED, or vibrate with a vibrator. good too. Also, the measurement system does not have to be provided with the notification means.

In the above-described embodiment, the error detection means 32 stores the measured values from the measuring instrument 2 and saves them. and a calculation means (not shown) for performing a predetermined calculation, and the presence or absence of an error is detected based on a predetermined value from the calculation result of the calculation means. good too. For example, it is possible to acquire the calibration timing of the measuring device from the information transmitting means of the measuring device, detect whether the calibration timing is approaching, and detect an error when the calibration timing is approaching.

Further, for example, in the case of a measurement system that sequentially measures a workpiece processed by a predetermined processing machine as the measurement object W (see FIG. 1), the external device measures the measured values of the workpiece. Storage means for storing the results and analysis information for analyzing the measurement results, analysis means for calculating the measurement results stored in the storage means and comparing them with the analysis information to analyze trends, etc., and analysis means analysis determination means for determining whether or not the analysis result is within a predetermined range based on the analysis result by When determined, an error may be detected.

Note that when the analysis result is within a predetermined range, for example, when a threshold for error detection is set, the analysis result approaches that threshold and the range up to the threshold that should warn that an error will soon occur. It is when there is an analysis result within. The analysis of the measurement results is, for example, statistical processing of the measurement results, and analysis of information about the measuring equipment including the measured values, such as quality level, yield, and tolerance.
In short, the error detection means only needs to be able to detect the presence or absence of an error based on the information of the measuring device, such as statistical processing, analysis results, and calculation results of the measurement results, and the detection method is not particularly limited. Further, the error information transmission means only needs to be able to transmit an error as error information to the measuring instrument, and the content of the error information may be any error detected by the error detection means. good.

In the above-described embodiment, the output stopping means 81 stops the output of the measured value by the measured value output means 6 in order to reliably notify the error information, but the output stopping means stops the measurement for another purpose. good too. For example, in the case of renting the measurement system, when the rental period has passed, the measurement may be stopped by the output stopping means assuming that the rental period has passed as an error. In short, the output stop means only needs to stop the output of the measured value by the measured value output means based on the error information.

In the above embodiment, the measured value output means 6 outputs measured values to the display means 5 and the information transmission means 7, but the measured value output means outputs only one of the display means and the information transmission means. The measured value may be output, or the measured value may be output to other means. In short, it is sufficient that the measured value output means can output the obtained measured value.
In the above embodiment, the output stop means 81 stops the measured value output means 6 from outputting the measured values to the display means 5 and the information transmission means 7. The output of the measured value to either one of them may be stopped, or the output of the measured value by the measured value output means to the other means may be stopped. In short, the output stop means only needs to stop the output of the measured value by the measured value output means based on the error information.

In the above-described embodiment, the external device 3 is a release command transmitting means for transmitting a release command to the measuring device 2 to release the suspension of the output of the measured value by the output suspending means 81 and restart the output of the measured value by the measured value output means 6. 34, the measuring instrument 2 includes a cancellation reception means 10 for accepting a cancellation command, and when the cancellation command is received, the stop of the output of the measured value by the output stop means 81 is canceled and the measured value output means 6 outputs the measured value. However, the measurement system does not include means for canceling the suspension of the measured value output by the output suspending means and restarting the output of the measured value by the measured value output means. good too.
Although the program used in the external device 3 in the measurement system 1 was previously installed in the external device 3 in the above embodiment, it may be installed in the external device later.
