The detection recognition points E11 and E12 are arranged so that urine can accurately recognize the detection start and the detection end when color detection is realized. Meanwhile, after detection is completed, the urine detection collection device can be cleaned by using the hollow structure without polluting other test papers. In this embodiment, the detection and identification points may be a black detection and identification point when the test paper substrate is set to be white, or a white detection and identification point when the test paper substrate is set to be black, and in this embodiment, a third detection and identification point E13 may be further added, where the third detection and identification point E13 may be different colors to identify a specific position of the detection and identification point in a roll of test paper, and when the color of the test paper is analyzed, the third detection and identification point E13 is analyzed at the same time, so as to determine whether the test paper roll should be replaced or other functions should be implemented.

Example 5

To better illustrate the invention, the invention also provides an example 5:

as shown in fig. 11, in example 5, specifically, the automatic urine collection and detection device as described above is included, and the automatic urine collection and detection device performs urine detection according to the following steps:

(2) Performing white balance operation of the color sensor;

In this embodiment, the first detection and identification point and the second detection and identification point may be set respectively according to the color of the test paper substrate, for example, when the test paper substrate is white, the first detection and identification point and the second detection and identification point may be set respectively to black; when the test paper substrate is set to black, the first and second detection recognition points may be set to white.

In this embodiment, the method further includes the following steps:

The third detection recognition points are arranged in the target segments to be detected, each target segment to be detected is provided with a unique third detection recognition point, the detection is carried out together with the color of the infiltrated test paper, and the distance between the target segment to be detected and the tail end or the beginning end of the test paper is obtained through the detection result.

Specifically, the color detection sensor respectively collects R, G, B three data, and after the collection is finished, the data are processed according to the following steps:

(6) Taking a certain data volume from each data set according to sequence numbers to form a data set, and searching whether the range between the data in the data set is larger than a first range; if the range is smaller than or equal to the first range, discarding the group of data, and judging the next group of data; the first range is a minimum difference between the RGB value corresponding to the color closest to white and the white RGB value in the color possible to appear in the to-be-detected index, in this embodiment, the detected minimum difference between the color RGB value closest to white and the white RGB value in the to-be-detected index is 30, and in other embodiments, the size of the first range may be adjusted according to different to-be-detected indexes to realize more accurate screening of data.

The reason why the data of the group is extremely bad is that in order to find the data of urine detection, we need to find the trough of the data of the group in the test paper with white as the base color, so as to realize the screening of the data, so that we judge whether the trough exists in the data of the group through extremely bad. Of course, in other embodiments, a black-based test strip may be used to find the peak of the set of data. It can also be judged by the extreme difference.

The data amount here may be selected to be a suitable data amount, for example, 20 data as a group; the data can be comprehensively judged according to other data volumes acquired by color detection, and in other embodiments, the data can be increased or decreased according to the actual acquired data volumes.

(7) The extremely difference is larger than the first range, the minimum value and the corresponding serial number in the data set are output, then the next data set is judged, the minimum value is repeated, and the minimum value is output at the same time; in this embodiment, the minimum sequence number of the next set of data is different from the minimum sequence number of the previous set of data by 4 sequence number units, or 5 sequence number units, which is considered by comprehensively considering the calculation amount and the comprehensiveness of the screening data, however, in other embodiments, the minimum sequence number of the next set of data may be different from the sequence number of the previous set of data by 1 sequence number unit, so that the calculation amount is increased, but the screening is more comprehensive. If a larger sequence number unit is selected, the amount of computation can be reduced accordingly.

(8) R, G, B, respectively obtaining a plurality of minimum values and serial numbers, screening whether data with serial numbers within a second range exist in serial numbers corresponding to the minimum values of the batch, if yes, taking the minimum value in the smaller serial number difference of the batch, outputting the serial number corresponding to the point, discarding the rest data, and if the serial number corresponding to the output minimum value is repeated, outputting at the same time; the second range is the difference between the minimum sequence numbers of the two adjacent sets of data.

In step (8), a plurality of data are prevented from being selected in a certain downward trend curve, so that the data with the sequence numbers corresponding to the minimum values of the batch differing in a second range are selected, the minimum values are adopted, the rest is omitted, the second range can be realized by adopting 4 or 5, and in other embodiments, the second range can be adjusted according to actual requirements.
