Embodiment 1

[0037] figure 1 A flow chart of a trademark identification method of this embodiment is schematically given, as figure 1 Shown: described brand identification method comprises the following steps:

[0038] (A1) Detect the sample and output the measured value of the elements in the sample;

[0039] (A2) Brand identification is carried out according to the measured value of elements in the sample and the range of elements of the brand;

[0040] (A3) Outputting the grade identification result.

[0041] Further, the grade element range includes a standard range, a tolerance range and an identification range.

[0042] The standard range mentioned is the specified range of elements in the brand, and generally adopts the standard range required by the national standard of the brand. The tolerance range and identification range can be set according to the user's acceptance. If the measured value of the element in the sample exceeds the identification range, the brand identificatio...

Embodiment 2

[0067] An application example of the trademark identification method in Embodiment 1 of the present invention. figure 2 Schematically shows the relationship diagram of the brand element range of the brand recognition method of this embodiment, as figure 2 As shown, in this application example, the standard range of brand elements adopts the standard range required by the national standard; the tolerance range is related to the standard range and tolerance factor, specifically: [lower limit of standard range - (upper limit of standard range - lower limit of standard range) × Tolerance factor] ~ [lower limit of the standard range + (upper limit of the standard range - lower limit of the standard range) × tolerance factor], the tolerance factor can be set freely according to the demand, such as setting 0.25; the recognition range is set as: (lower limit of the standard range / 2)~(2·Upper limit of the standard range), if the lower limit of the identification range≤0.5%, then set...

Embodiment 3

[0089] This embodiment provides a brand recognition method. The difference from Embodiment 1 is that in the process of automatic brand recognition, if the brand name of the first partition and / or the second partition is found, the grade of the third partition will not be partitioned. Or sort and display to improve the efficiency of brand recognition and improve the accuracy of brand recognition.

Abstract

The invention relates to a method for identifying designations. The method for identifying designations comprises following steps: (A1) detecting samples and outputting measurement values of elements of the samples; (A2) identifying designations according to the measurement values of elements in the samples and a designation element range; (A3) outputting designation identification results. The method has advantages such as automatic query and automatic ranking of designations.

Description

technical field [0001] The invention relates to the grade identification of metal samples, in particular to a method for automatically recognizing and sorting the grades of the measured values ​​of the elements in the sample according to a direct-reading spectrometer. Background technique [0002] The grade generally refers to the general designation of a class of metals with similar element content and performance. For such metal samples, iron or aluminum may only be distinguished from the appearance, and the brand of the metal sample cannot be determined, so it is impossible to know other types of metal elements that may be contained in the metal sample. Especially for scrap metal recycling customers, they often receive a variety of samples, and always want to know the grades of the samples and the types of elements contained in scrap metal at the first time, so as to carry out subsequent recycling operations on scrap metal. At present, the field of automatic identificati...
