Description

[Detailed description of the invention] (1) Technical field of the invention The present invention relates to an automatic measuring device.

Especially the place! In measuring instruments and test machines that implode the equipment (CPU), without using software programs written in languages such as assembler and Python.

The present invention relates to an automatic measuring device in which display data and test specifications are systematically coded and a desired 11 constant can be automatically performed simply by inputting the coded data.

°-(2)-Technical background When electrical equipment such as full and ttf coils and transformers, printed circuit boards, and units are manufactured, these electrical equipment and parts are specified in the specifications. It will be inspected to see if it passes nine standards.

In order to perform this inspection, various measurement items are set up depending on the type of equipment component to be tested.

A measured value is obtained for each item under the respective measurement conditions, and it is determined whether this measured value is within the measurement standard. For example, in addition to coils and transformers that have a pair of terminals on the primary and secondary sides,
There are nine types of intermediate taps with one or more intermediate taps on each side, but each type has each of these structures.

DC resistance, inductance, turns ratio, polarity, impedance, and insulation resistance between terminals for a given combination.

Dielectric strength voltage, etc. are measured. At this time, it is important to know what kind of jig to use for this measurement, as well as the measurement items and applied voltage.

Conventionally, measurement devices with a CPUt imploded have been used. However, in order to operate this conventional measuring device9, for example, in the case of coils and transformers, it is necessary to create a software program that incorporates measurement items, measurement standards, and measurement conditions for each type of structure. Since it is necessary to use basic and assembler languages to create software programs, it takes a long time to create programs.
Moreover, there was a problem in that an interrogation technician who understood the above language was required.

(4) Purpose of the Invention As stated above, the present invention aims to solve the problem of not being able to easily obtain measurement results with the conventional CPU built-in measuring device, by converting 9-display data and test specification T-coded data into data. The present invention provides an automatic measuring device #t that allows desired measurement results to be obtained simply by inputting information.

The specific items of the test object, test conditions, and test specifications as described above can be prepared in a table for all cases considered in advance. If it is possible to create a table in this way, the display data such as circuits corresponding to each item in this table and the measuring equipment, jigs, etc. necessary to perform nine tests in accordance with the test specifications can be stored in external memo 17 in advance.
One test execution program can be created by storing K and reading out only the necessary parts to the display data etc. storage section, extracting and reading out these display data, measuring devices, etc. in a table and combining them. At this time, if the items in the table can be selected by entering data to be written in the specifications, there is no need for a special language for creating a software program such as Basic Yaa Seven Pla.
