Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to an apparatus for automatically recognizing calibration information of an object to be measured in a component analyzer.

[Background of the Invention] An optical component analyzer for irradiating an object to be measured with light having a predetermined light wavelength and measuring the optical attenuation of the reflected light to detect a component such as moisture of the object to be measured is There is an error in the measured value due to the temperature rise of the analyzer during measurement of the component of the measured object, the change with time of the analyzer, the drift, etc.Therefore, in order to calibrate the measured value inside the component analyzer Calibration information that matches the measurement object is input to the storage unit inside the analyzer, and the corresponding calibration information that has been input in advance is extracted from the storage unit for each predetermined measured object, and the detected value is based on this. Is calculated to obtain an appropriate measurement value of the object to be measured.

By the way, conventionally, when measuring many kinds of DUTs particularly continuously, the calibration information corresponding to the DUTs stored in the analyzer for each DUT is operated and taken out each time. When a large number of types of measured objects are required, a marker correspondence table corresponding to the measured objects is created and the analyzer calibrates the corresponding measured objects based on the correspondence table. I was supposed to retrieve the information.

However, such a manual work requires a long time for the collation work, and sometimes the collation work may be erroneous, and the number of types of objects to be measured becomes large, and the automation of this work or the like is not possible. It was requested.

[Object of the Invention] The present invention was devised in view of the above-mentioned conventional problems, and even when the number of types of measured objects to be measured increases, calibration information and the like that match the measured objects. It is an object of the present invention to provide an apparatus for automatically recognizing calibration information of an object to be measured in a component analyzer capable of automatically taking out the measured value and obtaining an appropriate measured value.

It is configured such that the component analysis information of the measurement object 12 is created.

[Embodiment of the Invention] The invention will be described below based on an embodiment shown in the drawings.

FIG. 1 is a schematic diagram showing an outline of a component analyzer according to the present invention.

In the drawings, reference numeral 1 indicates a light source lamp.

The light emitted from the light source lamp 1 passes through the condensing lens 2 and the optical filters 5 and 6 provided on the rotating disk 4 rotated by the motor 3, thereby, for example, moisture of a predetermined object to be measured. The reference light 7 having a light wavelength that is not absorbed by the measurement light and the measurement light 8 having a light wavelength that is absorbed by the moisture of the object to be measured are separately formed.

These lights 7 and 8 are radiated via the first reflecting mirror 9 and the irradiation lens 10 to the object to be measured 12 placed on the measuring dish 11 placed on the lower surface of the analyzer, and the object to be measured 12 is irradiated. The reference light 7 reflected without being absorbed by moisture and the measurement light 8 absorbed by moisture and attenuated and reflected are condensed by the second condenser lens 13 provided on the upper part of the analyzer, and the light receiving element 1
4 is received.

By the way, with this component analyzer, there are a wide variety of types of DUTs 12 for measuring components such as water, and therefore, measurement for detecting an appropriate measured value for each predetermined DUT 12 is performed. The value calibration information is previously input to the storage unit 20 of the analyzer.

A flat side wall portion 30 is formed on the side surface provided on one end side of the measuring dish 11, and, for example, eight recess portions 21 ... Are provided in series on the surface thereof.

Then, the black seals 22 ... Are attached to any two of the recessed portions 21 ... And the marker portions 31 are formed.

Thus, ^{2 eight} According to this embodiment, i.e. 25
Six types of marker parts 31 can be created.

In addition, a convex portion is provided on the bottom surface of the measuring dish 11, and a concave portion having substantially the same shape as the convex portion is formed on the bottom surface of the analyzer, and the measuring dish 11 is fitted into the concave portion. The marker part 31 may be detected only by the fitting operation.

Here, on the analyzer side, a detector 23 composed of a light emitting diode or the like is provided at a position facing the hollow portion 21 provided on the measuring dish 11, and a black seal is formed by the detector 23. The marker portion 31 thus formed detects the type of the object to be measured 12, and the calibration information of the object to be measured 12 placed on the measuring dish 11 can be easily taken out.

That is, as shown in FIG. 3, by detecting the marker portion 31 provided on the measurement dish 11 by the detector 23, the type of the object 12 to be measured placed on the measurement dish 11 is recognized, and Calibration information of the DUT 12 (calibration curve, etc.)
Are retrieved from the storage unit 20.

Then, the calibration information retrieved from the storage unit 20 is taken into consideration by the arithmetic processing unit 24.

Here, the calibration information is used as a reference for the measurement values obtained by the component analysis of the object to be measured, and finally an appropriate measurement value is detected, and the component analysis information of the object to be measured is created. It will be.

[Effect of the Invention] Thus, the present invention has the above configuration.

The device for automatically recognizing calibration information of an object to be measured in the component analyzer according to the present invention does not need to manually retrieve various kinds of calibration information of the object to be measured from the storage unit of the analyzer as in the conventional case. It is said that the component analyzer can identify the measured object and that the calibration information of the measured object can be recognized simply by setting the measuring dish with the marker part on which the measured object is placed. .

Therefore, in a large amount of DUTs, when the types are all different, when measuring DUTs of different types, even if the measurement is performed in a different order, the DUT is detected by the marker part. It is possible to provide a component analyzer capable of instantaneously specifying the type and taking into account the calibration information thereof, and thus obtaining an accurate measurement value in an appropriate measurement state.
