Abstract

PURPOSE:To achieve a higher measuring accuracy of a half-way position signal in comparison with a moving distance of equipment to be inspected, by a method wherein the half-way position signal outputted from the equipment being inspected is converted into decimal and multiplied by position signal output constants of shafts to perform segment display. CONSTITUTION:Receiving inputs of a position signal (scan signal or pitch signal) 2 outputted from equipment 1 to be inspected and a control signal (shaft specification signal or the like) 3, an I/O simulator 4 selects the signal 2 desired to be measured to be outputted to a data converting section 5 and outputs the signal 3 to a personal computer 7 separately. Then, a data conversion program is started with the personal computer 7 to convert the signals into decimal signals 6 which are outputted to a constant multiplying section 8. Subsequently, a constant multiplying program is started with the personal computer 7 and receiving an input of the position signal 9 obtained by multiplication, a display section 10 for scanning and a display section 11 for pitch display a scan signal and a pitch signal decimally. Such a segment display provided a higher half-way position signal measuring accuracy in comparison with a moving distance of the equipment being inspected.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides an I
By importing the data into a 10 simulator, displaying segments, and comparing with the travel distance, it is possible to perform an intermediate accuracy measurement test, and is particularly applicable to high-precision ultrasonic probe drive devices that constitute microcomputer-applied equipment.

[Conventional technology]

Conventionally, a mid-way position signal measurement test for each axis output from a device under test has had the disadvantage that mid-way accuracy measurement tests cannot be performed because there is no indication of the operating state in the display for set values.

Incidentally, related devices of this type include, for example, Japanese Unexamined Patent Application Publication No. 61-29909, No. 61-27585, and No. 61-27585.

[Problem that the invention seeks to solve]

In the conventional technology described above, there is a problem in that mid-way position signal accuracy measurement tests for each axis output from the device under test display the set values, but there is no indication of operation status, making it impossible to perform mid-way accuracy measurement tests. .

An object of the present invention is to
10 simulator, convert the ON/OFF signal to a decimal number, multiply it by the position signal output constant of each axis, and display it in segments.

By comparing the moving distance of the device under test, it is possible to perform an intermediate position signal accuracy measurement test.

This provides an improvement in the accuracy of position signal measurement during the process.

[Means for solving problems]

The above purpose is to capture the position signal that is being output from the device under test using the I10 simulator, convert the ON/OFF signal into a decimal number, multiply it by the position signal output constant of each axis, and display it in segments. This is achieved by making it possible to perform an intermediate position signal accuracy measurement test by comparing the distance traveled by the inspection device.

[Effect]

The position signal measuring device uses an I10 simulator to capture the position signal that is being output from the device under test, and then uses the 0N1
By converting the 0 F F signal into decimal, multiplying it by the position signal output constant of each axis, displaying it in segments, and comparing it with the moving distance of the device under test, it is possible to perform position signal accuracy measurement tests midway. It is something.

This improves the accuracy of position signal measurement during the process.

〔Example〕

FIG. 1 shows a configuration diagram of the position signal measuring device.

A position signal (2) (scan signal, pitch signal) and a control signal (3) (data transfer signal, pulse acquisition signal, axis designation signal) are output from the device to be inspected (1) to the simulator (4).

Next, the position signal to be measured is selected and output to the data conversion section 5. The axis designation signal is also output to the computer with 7.

Next, the data conversion program is started from the computer, and 10
Converted to base number. The converted position signals of 6 are output to the constant multiplier of 8.

Finally, the constant multiplication program is started from the computer.
According to this embodiment, the multiplied position signal 9 is displayed on display units 10 and 11 in which the scan signal and the pitch signal are displayed in decimal notation. Since there is no indication of the set value during operation, it is difficult to perform accuracy measurement tests during the process.
By importing the data using an I10 simulator, converting it to a decimal number, multiplying it by the position signal output constant of each axis, displaying it in segments, and comparing it with the moving distance of the device under test, the accuracy of the position signal during measurement was improved.

〔Effect of the invention〕

In the position signal measurement test of the device under test, the conventional setting values are displayed, but there is no display during operation, making it difficult to measure accuracy during the process. By multiplying the signal output constant, displaying it in segments, and comparing it with the moving distance of the device under test, there is an effect of improving the accuracy of the position signal on the way.
