Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a testing and inspection work automation system that is applied to testing and inspecting various types of equipment and products.

[Conventional technology]

Conventionally, in the testing and inspection of various types of equipment and products, inspectors or workers visually read the values indicated by measuring instruments, compare them with the standard values indicated for each equipment or product, and then make judgments manually. It is summarized in the record.

However, such a method has the following drawbacks.

(1) Misreading of input/output indicated values occurs.

) Mistakes in filling in or transcribing the indicated values as above occur.

(3) Misjudgment occurs, such as not satisfying various tolerance values such as accuracy and error.

(4) Recording formats vary depending on the customer.
It's flying around.

(5) Records may be unclear and difficult to read.

(6) It takes a lot of time to create records.

(Collection, recording, calculation 1 judgment, form compilation 1 preparation) (F) Inspectors may have to travel to the manufacturer's factory.

(8) Even if data can be collected, it is difficult to utilize it as statistical management data.

[Problem that the invention seeks to solve]

The present invention was proposed in view of these circumstances, and
There are no simple human errors such as mistakes in reading, writing, or transcription, and the results of comparison with the pre-given calculation formula 1 judgment standard value are shown, eliminating any miscalculations or misjudgments, and making it easy to record. It saves labor by shortening collection time and recording time.
Furthermore, the present invention aims to provide a testing and inspection work automation system that facilitates the collection and collection of data and contributes to improving product quality by utilizing statistical quality control techniques.

[Means for solving problems]

To this end, the present invention measures the input that acts on the test item and the output of the test and inspection results with a high-precision dedicated detector, introduces the measurement data into a computer, and uses dedicated software. It is characterized in that it is used to perform calculation processing for comparing data and determining comparisons with reference values, and to record the processing results.

[For production]

With the above configuration, simple human errors such as mistakes during reading, writing, and transcription are completely eliminated, and the results of comparison with the pre-given Equation 1 judgment reference value are displayed to eliminate miscalculations and errors.
We have created a test and inspection work automation system that eliminates all erroneous judgments, saves labor by shortening record collection and writing time, and also facilitates data collection and collection and contributes to improving product quality by utilizing statistical quality control methods. Obtainable.

〔Example〕

An embodiment in which the test and inspection work automation system of the present invention is applied to the accuracy test of a pressure transmitter will be explained with reference to the drawings. FIG. 1 is a system diagram thereof, and FIG. 2 is a detailed system diagram of the same dedicated software.

In Fig. 1, pressurization input is applied from the pressure source 2 to the pressure transmitter of the product under test 1 as in the conventional inspection method, and in the process of outputting the signal output 3 representing the accuracy test result, the high-precision pressure detector 4 measures the input amount, and a high precision voltage/iiE current detector 5 measures the output amount.

This high precision pressure detector 4 and high precision voltage/current detector 5
The system is configured to read data directly, perform data processing in the attached data conversion/processing unit, and connect to eight general-purpose computer terminals.

Note that these high-precision pressure detector 4 and high-precision voltage/current detector 5 measure physical quantities corresponding to test inspection items, respectively.
In other words, the former has the function of detecting pressure and the latter of voltage/current, and converting/outputting this into computer-processable data.
This is a high-precision dedicated detector that has additional functions such as storing input data f within 24 hours if necessary. By combining this with the video camera 6 and making full use of the communication line 11, it is possible to carry out the inspection simultaneously at any remote location other than the place where the inspection is to be carried out, and to obtain the necessary records.

High precision pressure detector 4. The signals transmitted from the high-precision voltage/current detector 5 and the video camera 6 are data-processed by a general-purpose computer 8, and the input/output data is matched and necessary It performs arithmetic processing such as calculation processing to determine whether tolerance accuracy is satisfied, displays the screen on the CRT 9, and prints out the necessary data on the printer 10 as a recording format. A recording format/data screen or a video camera image can be arbitrarily selected from the screen by performing necessary operations. These data and images can be checked on the CRT 9 at any remote location at the same time as the inspection site via the communication line 11, and records can be obtained on the printer 10.

〔Effect of the invention〕

In short, according to the present invention, the input that acts on the test item related to the test inspection item and the output of the test inspection result are each measured by a high-precision dedicated detector, and the same measurement data? Introduced into a computer and collated data using special software.

By performing calculation processing for comparison judgment with standard values and recording the processing results, simple human errors such as mistakes during reading, writing, and transcription are completely eliminated, and calculation formula 1 judgment given in advance The results compared to the standard values are shown, eliminating any miscalculations or misjudgments, and saving labor by shortening the time required to collect and write records. Furthermore, data collection and collection are made easier, and statistical quality control methods can be utilized. This will result in a testing and inspection work automation system that contributes to improving product quality.
The present invention is extremely useful industrially.
