[0172] The present invention will be further described in detail below by means of specific embodiments in conjunction with the accompanying drawings. Similar elements in different embodiments are numbered with associated similar elements. In the following embodiments, many detailed descriptions are provided to enable the present application to be better understood. However, those skilled in the art will readily appreciate that some of the features may be omitted in different circumstances, or may be replaced by other elements, materials, or methods. In some cases, some operations related to the present application are not shown or described in the specification. This is to avoid the core portion of the present application being overwhelmed by excessive descriptions, and for those skilled in the art, it is not necessary to describe these related operations in detail. They will fully understand the related operations based on the description in the specification and the general technical knowledge in the art.

[0173] In addition, the features, operations, or characteristics described in the specification may be combined in any appropriate manner to form various embodiments. Furthermore, the steps or actions in the method description may be reordered or adjusted in a manner readily apparent to those skilled in the art. Therefore, the various sequences in the specification and drawings are provided solely for the purpose of clearly describing a particular embodiment and are not intended to be mandatory, unless otherwise specified.

[0174] The serial numbers assigned to components herein, such as "first," "second," etc., are used solely to distinguish the objects being described and do not convey any sequential or technical meaning. References to "connection" and "coupling" herein, unless otherwise specified, include both direct and indirect connections (couplings).

[0175] Dry chemical testing is relative to wet chemical testing. Dry chemical testing refers to adding a sample to be tested (e.g., a sample in a flowing or liquid state) to a reagent strip specifically produced for different test items. The reagent strip is generally arranged with multiple color blocks, each corresponding to a test item. When the sample to be tested is added to the color block, it will undergo a specific chemical reaction with the reagent on the color block, causing the color of the color block to change. The reagent strip can generally be referred to as a dry chemical test paper. Figure 1 is a schematic diagram of a dry chemical test paper. The dry chemical test paper 90 includes multiple color blocks 99 (7 ​​color blocks 99 in the figure), for example, multiple color blocks 99 are distributed in sequence along the length direction (or axial direction) of the dry chemical test paper 90; each color block 99 includes a pre-set reagent, so that each color block 99 can indicate the test result of a test item after reacting with the sample to be tested. In some embodiments, the types of test items include but are not limited to test items such as red blood cell count and white blood cell count. In addition, for any dry chemical test paper, after it is produced, the position of each color block 99 in the dry chemical test paper is determined.

[0176] There are many factors that affect the inaccuracy of dry chemical test results, but what is troubling is that when all conditions are normal, the test results of some color blocks of dry chemical test paper may still be inaccurate. In response to this phenomenon, the applicant found that dry chemical test strips generally have multiple color blocks, each color block corresponding to a test item. In actual situations, the optimal reaction time of each color block may be inconsistent. For example, taking the dry chemical test strips that can include more than ten test items such as white blood cells, urobilinogen, protein, glucose, etc., there are differences in dry chemical test strips from different manufacturers, and the optimal reaction time of each item on the strips of some manufacturers is inconsistent. For example, the optimal reaction time of the color blocks of the same test item on dry chemical test strips from different manufacturers is inconsistent. For another example, the optimal reaction time of the color blocks of different test items on dry chemical test strips from different manufacturers is inconsistent. For another example, a specific dry chemical test strip from the same manufacturer has color blocks with different optimal reaction times. A specific example is that the optimal time for the white blood cell item in some dry chemical test strips is 120s, while the optimal reaction time for other items is 60s.

[0177] In one solution, after the dry chemical detection device adds samples to the dry chemical test paper in the same sample addition area, the dry chemical test paper will continue to be transported in a certain direction, and then all test items on the dry chemical test paper will be tested simultaneously at a fixed detection time (or detection area). This will result in the test items corresponding to some color blocks on the dry chemical test paper not being tested within their optimal reaction time, which often leads to inaccurate test results.

[0178] Taking the above problems into consideration, the present application presets reaction times for color blocks so that color blocks with different optimal reaction times can be distinguished. For example, a first color block corresponding to a first test item and a second color block corresponding to a second test item, for these two color blocks, the first color block is preset with a first reaction time, and the second color block is preset with a second reaction time different from the first reaction time; the color block information of the first color block that has undergone the first reaction time after being added to the biological sample to be tested is obtained to obtain the detection result of the first test item, and the color block information of the second color block that has undergone the second reaction time after being added to the biological sample to be tested is obtained to obtain the detection result of the second test item.

[0179] The dry chemical detection device is first described below.

[0180] Please refer to Figure 2(a), the dry chemical detection device in some embodiments includes a carrying component 10, a sample adding component 30, an imaging component 50 and a processor 70; please refer to Figure 2(b), the dry chemical detection device in some embodiments also includes a test paper area 20, which is described in detail below.

[0181] The carrier 10 is used to place dry chemical test paper 90. For ease of description, the concept of a test paper area 20 can be introduced, and the carrier 10 is used to place the dry chemical test paper 90 located in the test paper area 20. One test paper area 20 can hold one dry chemical test paper 90. In some embodiments, there can be one or more test paper areas 20. In other words, the dry chemical detection device can include one or more test paper areas 20. The figure shows a schematic diagram of a dry chemical detection device including 10 test paper areas 20.

[0182] In some embodiments, please refer to Figure 3, the carrying component 10 includes a conveying component 11 and a power mechanism 13. The conveying component 11 is driven by the power mechanism 13 to convey the dry chemical test paper 90 thereon along a preset direction, so as to drive the dry chemical test paper 90 to be conveyed along the preset direction among the multiple test paper areas 20 included in the dry chemical detection device, for example, from one test paper area 20 to the next test paper area 20 in the preset direction; more specifically, the dry chemical test paper 90 can be transported in this way: the dry chemical test paper 90 is transported to a test paper area 20, stays for a period of time, and then is transported from the current test paper area 20 to the next test paper area 20 along the preset direction.

[0183] In some embodiments, the conveying component 11 is driven by the power mechanism 13 to periodically convey the dry chemical test paper 90 thereon along a preset direction with a second preset period, so as to drive the dry chemical test paper 90 to be conveyed along the preset direction in the multiple test paper areas 20 included in the dry chemical detection device; more specifically, the dry chemical test paper 90 can be transported in this way: the dry chemical test paper 90 is conveyed to a test paper area 20 and stays for a period of time, and then is conveyed from the current test paper area 20 to the next test paper area 20 along the preset direction, wherein the time interval from the dry chemical test paper 90 entering one test paper area 20 to entering the next test paper area 20 is the above-mentioned second preset period, or the time interval from the dry chemical test paper 90 leaving one test paper area 20 to leaving the next test paper area 20 is the above-mentioned second preset period.

[0184] In some embodiments, the dry chemical test paper 90 placed on the carrier 10 is relatively stationary with respect to the imaging component 50. Generally, the imaging component 50 does not move. Therefore, if the dry chemical test paper 90 placed on the carrier 10 is relatively stationary with respect to the imaging component 50, the dry chemical test paper 90 placed on the carrier 10 is also stationary and does not move. That is, when the dry chemical test paper 90 is located in a test paper area 20, the dry chemical test paper 90 will remain in this test paper area 20.

[0185] For the convenience of discussion in this article, the situation where the supporting component 10 includes the transmission component 11 and the power mechanism 13 is called a dynamic scene, and the situation where the dry chemical test paper 90 placed on the supporting component 10 and the imaging component 50 are relatively stationary is called a static scene.

[0186] The sample adding component 30 is used to add the biological sample to be tested to the color block 99 on the dry chemical test strip 90. For example, the sample adding component 30 is used to add the biological sample to be tested to the color block 99 on the dry chemical test strip 90 located on the carrier 10. In other words, the sample adding component 30 is used to add the biological sample to be tested to the color block 99 on the dry chemical test strip 90 located in the test strip area 20. The sample adding component 30 can perform the sample adding action—i.e., the action of adding the biological sample to the color block 99 on the dry chemical test strip 90—under the control of the processor 70.

[0187] In some embodiments, the biological sample to be tested includes a urine sample, a body fluid sample, and / or a vaginal secretion.

[0188] There are many ways to implement the sample adding component 30, and several of them are listed below.

[0189] In some embodiments, referring to FIG. 4( a ) or FIG. 4 ( b ), the sample loading component 30 may include one or more sample loading mechanisms 31 .

[0190] In some embodiments, the sample loading mechanism 31 can only add the biological sample to be tested to one color block 99 at a time - this type of sample loading mechanism 31 may be referred to as a first type of sample loading mechanism 31; for example, please refer to Figure 4(a), the sample loading mechanism 31 only includes one sample needle 31a; in this way, the sample loading mechanism 31 can only add the biological sample to be tested to one color block 99 at a time; when the sample loading mechanism 31 adds the biological sample to be tested to the dry chemical test paper 90 located in the test paper area 20 or the supporting component 10, the sample loading component 30 can drive the sample loading mechanism 31 to move to add the biological sample to be tested to each color block 99 in the dry chemical test paper 90, for example, the sample loading mechanism 31 moves along the axial direction of the dry chemical test paper 90 to complete the addition of the biological sample to be tested to each color block 99 of the dry chemical test paper 90. In such an example, it can also be considered that the sample loading mechanism 31 is moving within the same test paper area 20.

[0191] In some embodiments, the sample adding mechanism 31 can add the biological sample to be tested to multiple color blocks 99 at one time - it is not a problem to refer to this type of sample adding mechanism 31 as a second type of sample adding mechanism 31; for example, referring to FIG4(b), the sample adding mechanism 31 may include multiple sample needles 31a (shown in the figure is a schematic diagram including three sample needles 31a), so that the sample adding mechanism 31 can add the biological sample to be tested to multiple color blocks 99 at one time; it can be understood that if the number of sample needles 31a of the sample adding mechanism 31 is the same as the number of color blocks 99 on the dry chemical test paper 90, then the sample adding mechanism 31 can complete the addition of the biological sample to be tested to each color block 99 on the dry chemical test paper 90 at one time. If the number of sample needles 31a of the sample adding mechanism 31 is the same as the number of color blocks 99 on the dry chemical test paper 90, then the sample adding mechanism 31 can complete the addition of the biological sample to be tested to each color block 99 on the dry chemical test paper 90 at one time. If the amount is less than the number of color blocks 99 on the dry chemical test paper 90, although the sample adding mechanism 31 can complete the addition of the biological sample to be tested to multiple color blocks 99 on the dry chemical test paper 90 in one time, it still needs at least two times to complete the addition of the biological sample to be tested to each color block 99 on the dry chemical test paper 90. In this case, the sample adding component 30 can drive the sample adding mechanism 31 to move to add the biological sample to be tested to each color block 99 in the dry chemical test paper 90. For example, the sample adding mechanism 31 moves along the axial direction of the dry chemical test paper 90 to complete the addition of the biological sample to be tested to each color block 99 of the dry chemical test paper 90. In such an example, it can also be considered that the sample adding mechanism 31 is moving within the same test paper area 20.

[0192] In some embodiments, the sample loading component 30 may include only one sample loading mechanism 31 , and the sample loading mechanism 31 may be a first type of sample loading mechanism 31 or a second type of sample loading mechanism 31 .

[0193] In some embodiments, the sample loading component 30 may include multiple sample loading mechanisms 31 (for example, at least two), and these multiple sample loading mechanisms 31 may all be first-type sample loading mechanisms 31, or may all be second-type sample loading mechanisms 31; or even, these multiple sample loading mechanisms 31 may partially be first-type sample loading mechanisms 31, and partially be second-type sample loading mechanisms 31.

[0194] In some embodiments, the sample adding component 30 can only add the biological sample to be tested to the dry chemical test paper 90 located in a specific test paper area 20 .

[0195] In some embodiments, the sample adding component 30 is capable of adding the biological sample to be tested to the dry chemical test paper 90 located in at least two test paper areas 20; for example, the sample adding component 30 can move between at least two test paper areas 20 by driving the sample adding mechanism 31, thereby completing the addition of the biological sample to be tested to the dry chemical test paper 90 located in different test paper areas 20 through one sample adding mechanism 31; for another example, the sample adding component 30 can have multiple sample adding mechanisms 31, each sample adding mechanism 31 corresponding to a test paper area 20, and the sample adding mechanism 31 is used to add the biological sample to be tested to the dry chemical test paper 90 located in its corresponding test paper 20.

[0196] In some specific embodiments, the sample loading component 30 includes two independent sample loading mechanisms 31, such as a first sample loading mechanism 31 and a second sample loading mechanism 31. The first sample loading mechanism 31 can be either a first type sample loading mechanism 31 or a second type sample loading mechanism 31, and the second sample loading mechanism 31 can be either a first type sample loading mechanism 31 or a second type sample loading mechanism 31. In some embodiments, the first sample loading mechanism 31 and the second sample loading mechanism 31 can add the biological sample to be tested to different color blocks 99 in the same dry chemical test strip 90 at different loading times. In some embodiments, the first sample loading mechanism 31 and the second sample loading mechanism 31 can add the biological sample to be tested to different color blocks 99 in the same dry chemical test strip 90 in different test strip regions 20. For example, the first sample loading mechanism 31 adds the biological sample to be tested to a certain color block 99 in the dry chemical test strip 90 in one test strip region 20, while the second sample loading mechanism 31 adds the same biological sample to be tested to another color block 99 in the dry chemical test strip 90 in another test strip region 20.

[0197] The imaging component 50 is used to capture images, for example, to capture images of part or all of the dry chemical test paper 90 located on the supporting component 10, or to capture images of the dry chemical test paper 90 located in all or part of the test paper area 20.

[0198] In some embodiments, the imaging component 50 periodically photographs the dry chemical test paper 90 at a first preset period, for example, once every T seconds. In some embodiments, the second preset period is an integer multiple of the first preset period, which can be 1 or more multiples. For example, if the second preset period is 10 seconds, the first preset period is also 10 seconds. For another example, if the second preset period is 20 or 30 seconds, the first preset period is 10 seconds.

[0199] In some embodiments, referring to FIG. 5( a ), the imaging component 50 includes a global camera 51. The field of view of the global camera 51 can cover at least two of the multiple test strip areas 20 included in the dry chemical testing device. The global camera 51 is used to capture the dry chemical test strips 90 located in the at least two test strip areas. In some embodiments, the field of view of the global camera 51 can cover all of the test strip areas 20 included in the dry chemical testing device.

[0200] In some embodiments, the global camera 51 periodically photographs the dry chemical test paper 90 located in the at least two test paper areas 20 mentioned above with a first preset period, for example, once every T seconds; in some embodiments, the second preset period is an integer multiple of the first preset period, and the integer multiple can be 1 or multiple times; for example, the second preset period is 10s, and the first preset period is also 10s, and for another example, the second preset period is 20 or 30s, and the first preset period is 10s.

[0201] In some embodiments, referring to FIG. 5( b ), the imaging component 50 includes multiple local cameras 53 , for example, at least two local cameras 53 . The field of view of each local camera 53 is one of the multiple test strip areas 20 included in the dry chemical testing device, and different local cameras 53 have different test strip areas 20 corresponding to their respective fields of view. Each local camera 53 is configured to capture the dry chemical test strip 90 in the test strip area 20 corresponding to its respective field of view. In some embodiments, the number of local cameras 53 is the same as the number of test strip areas 20 included in the dry chemical testing device, i.e., each test strip area 20 corresponds to one local camera 53 .

[0202] In some embodiments, each local camera 53 synchronously and periodically photographs the dry chemical test paper 90 in the test paper area 20 corresponding to its respective shooting field of view with a first preset period, for example, each local camera synchronously (or simultaneously) photographs once every T seconds; in some embodiments, the second preset period is an integer multiple of the first preset period, and the integer multiple can be 1 or multiple times; for example, the second preset period is 10s, and the first preset period is also 10s, and for another example, the second preset period is 20 or 30s, and the first preset period is 10s.

[0203] The processor 70 can obtain the image captured by the imaging component 50 and determine the color information of the color block 99 on the dry chemical test paper 90 from the image, thereby obtaining the test result of the test item corresponding to the color block 99. The color block information herein refers to color-related information, such as RGB values.

[0204] The above are some instructions for the dry chemical test paper device.

[0205] In some embodiments, the dry chemical test paper 90 includes a first dry chemical test paper 91, or at least one type of dry chemical test paper 90 is the first dry chemical test paper 91. The first dry chemical test paper 91 has at least a first color block 01 corresponding to a first test item and a second color block 02 corresponding to a second test item. The first test item has a preset first reaction time T1, and the second test item has a preset second reaction time T2 that is different from the first reaction time T1. Those skilled in the art can set specific values ​​for the first reaction time T1 of the first color block 01 and the second reaction time T2 of the first color block 02 based on clinical experience. Generally, after the addition of the test sample, after the first reaction time T1, the reagent in the first color block 01 reacts sufficiently with the test sample, or the color information of the first color block 01 at this time can more accurately represent the test result. Similarly, after the addition of the test sample, after the second reaction time T2, the reagent in the second color block 02 reacts sufficiently with the test sample, or the color information of the second color block 02 at this time can more accurately represent the test result. It can be understood that the first dry chemical test paper 91 is a type of dry chemical test paper 90; the first color block 01 is a type of color block 99, and the first color block 02 is another type of color block 99. Therefore, in other words, the first dry chemical test paper 91 has at least two color blocks 99, such as at least the first color block 01 and the second color block 02, and each color block 99 corresponds to a test item.

[0206] In some embodiments, the sample adding component 30 is used to simultaneously add the same biological sample to be tested to the first color block 01 and the second color block 02 of the first dry chemical test paper 91 under the control of the processor 70; the imaging component 50 is used to photograph the first dry chemical test paper 91 after the sample adding component 30 adds the biological sample to be tested to the first color block 01 and the second color block 02 of the first dry chemical test paper 91 to obtain multiple images.

[0207] It should be noted that, in this article, "the sample adding component 30 is used to add the same biological sample to be tested to the first color block 01 and the second color block 02 of the first dry chemical test paper 91 at the same time under the control of the processor 70". The "simultaneously" involved here refers to the same time in the engineering sense. Generally, the sample adding component 30 will add the same biological sample to be tested to each color block in the first dry chemical test paper 91. If the sample adding component 30 cannot complete the addition of the biological sample to be tested to each color block in the first dry chemical test paper 91 at one time, it will need to be completed multiple times, and these multiple times are generally completed within a relatively short period of time. Therefore, it can be said that the same biological sample to be tested is added to each color block in the first dry chemical test paper 91 at the same time. For example, when the sample adding component 30 includes only one sample adding mechanism 31 and the sample adding mechanism 31 is a first type of sample adding mechanism 31, when the same biological sample to be tested is added to the first color block 01 and the second color block 02 of the first dry chemical test paper 91, the sample adding mechanism 31 will move to the corresponding positions respectively to complete two sample additions, one is to the first dry chemical test paper 91 The biological sample to be tested is added to the first color block 01, and the biological sample to be tested is added to the second color block 02 of the first dry chemical test paper 91. In this case, it is in accordance with the engineering sense of the term "simultaneously". For another example, when the sample adding component 30 includes two first-type sample adding mechanisms 31, the two first-type sample adding mechanisms 31 respectively add the same biological sample to be tested to the first color block 01 and the second color block 02 of the first dry chemical test paper 91 at the same time point, thereby achieving that the sample adding component 30 simultaneously adds the same biological sample to be tested to the first color block 01 and the second color block 02 of the first dry chemical test paper 91. For another example, when the sample adding component 30 includes one second-type sample adding mechanism 31, the two sample needles 31a in the second-type sample adding mechanism 31 respectively add the same biological sample to be tested to the first color block 01 and the second color block 02 of the first dry chemical test paper 91 at the same time point, thereby achieving that the sample adding component 30 simultaneously adds the same biological sample to be tested to the first color block 01 and the second color block 02 of the first dry chemical test paper 91.

[0208] The multiple images captured by the imaging component 50 include at least a first image and a second image. The first image is an image of the first dry chemical test paper 91 captured after the biological sample to be tested is added and a first reaction time T1 has elapsed. The second image is an image of the first dry chemical test paper 91 captured after the biological sample to be tested is added and a second reaction time T2 has elapsed. The processor 70 acquires the first and second images. The processor 70 determines first color block information from the first image and calculates a test result for a first test item corresponding to the first color block based at least on the first color block information. The processor 70 also determines second color block information from the second image and calculates a test result for a second test item corresponding to the second color block based at least on the second color block information.

[0209] In some embodiments, the first reaction time T1 and the second reaction time T2 can be calculated by the shooting cycle of the imaging component 50, or in other words, the first dry chemical test paper 91 is timed after the biological sample to be tested is added and the first reaction time T1 and the second reaction time T2 are passed. Therefore, in some embodiments, the imaging component 50 periodically photographs the first dry chemical test paper 91 at a first preset period to obtain multiple images; wherein: the first reaction time T1 is the time corresponding to M first preset periods after the biological sample to be tested is added to the first dry chemical test paper 91, and accordingly, the first image is the image of the first dry chemical test paper 91 obtained by photographing the first dry chemical test paper 91 after the biological sample to be tested is added and the first image is M first preset periods; the second reaction time T2 is the time corresponding to N first preset periods after the biological sample to be tested is added to the first dry chemical test paper 91, and accordingly, the second image is the image of the first dry chemical test paper 91 obtained by photographing the first dry chemical test paper 91 after the biological sample to be tested is added and the first preset periods; M and N are preset positive integers and the two are not equal.

[0210] For example, let's take the example of the first preset period being 10s, the first reaction time T1 being 30s, and the second reaction time T2 being 60s. At this time, the first reaction time T1 is the time corresponding to the three first preset periods after the biological sample to be tested is added to the first dry chemical test paper 91. Accordingly, the first image is the image obtained by the first dry chemical test paper 91 after the biological sample to be tested is added and the first dry chemical test paper 91 is photographed after the three first preset periods; the second reaction time is the time corresponding to the six first preset periods after the biological sample to be tested is added to the first dry chemical test paper 91. Accordingly, the second image is the image obtained by the first dry chemical test paper 91 after the biological sample to be tested is added and the first dry chemical test paper 91 is photographed after the six first preset periods.

[0211] In some embodiments, the reaction time can also be associated with the position. Therefore, in some embodiments, the processor 70 determines the first color block information from the first image, including: using the image information located in a preset first area of ​​the first image as the first color block information, the preset first area corresponding to the first color block 01 of the first dry chemical test paper 91; the processor 70 determines the second color block information from the second image, including: using the image information located in a preset second area of ​​the second image as the second color block information, the preset second area corresponding to the second color block 02 of the first dry chemical test paper 91.

[0212] For example, in the example of the global camera 51 plus a dynamic scene, the first color block 01 and the second color block 02 of the first dry chemical test paper 91 are added with the same biological sample to be tested at the same time. After the first reaction time T1, the first dry chemical test paper 91 will be transported to a specific test paper area 20, which may be referred to as the first test paper area 20 (assuming it is the fourth test paper area 20 from the middle left to the right in Figure 3). After the second reaction time T2, the first dry chemical test paper 91 will be transported to another specific test paper area 20 (assuming it is the sixth test paper area 20 from the middle left to the right in Figure 3), which may be referred to as the second test paper area 20. Since the first test paper area 20 and the second test paper area 20 are determined, the position of the first dry chemical test paper 91 in the first image and the second image is also determined and can be obtained without being based on the first image and the second image. For example, A dry chemical test paper 91 is at the location of the fourth test paper area 20 in the first image, for example, the first dry chemical test paper 91 is at the location of the sixth test paper area 20 in the second image; in addition, since the positions of the color blocks on the dry chemical test paper 90 are also determined and can be obtained without being based on the first image and the second image, that is, the position of the first color block 01 on the first dry chemical test paper 91 is determined and can be obtained without being based on the first image and the second image, and the position of the second color block 02 on the first dry chemical test paper 91 is also determined and can be obtained without being based on the first image and the second image, therefore, the position of the first color block 01 in the first image is determined and can be obtained without being based on the first image and the second image, and the position of the second color block 02 in the second image is determined and can be obtained without being based on the first image and the second image.

[0213] In some embodiments, the processor 70 can obtain the preset areas corresponding to the various color blocks on the dry chemical test paper 90 by the test paper type of the dry chemical test paper 90. The test paper type may refer to the number of color blocks and / or the type of color blocks (i.e., the test items or reaction times corresponding to the color blocks are different) of the dry chemical test paper 90. It is understandable that the processor 70 can obtain the test paper type of the dry chemical test paper 90 by scanning the dry chemical test paper 90 with a scanner, etc., or can obtain the test paper type of the dry chemical test paper 90 by the operator inputting the test paper type of the dry chemical test paper 90 through an input tool. Therefore, in some embodiments, before the processor 70 determines the first color block information from the first image and determines the second color block information from the second image, it also includes: obtaining the test paper type of the first dry chemical test paper 91; and obtaining the above-mentioned preset first area and the above-mentioned preset second area according to the test paper type of the first dry chemical test paper 91.

[0214] In some embodiments, the first dry chemical test paper 91 further has a third color block 03 corresponding to a third test item; in such an embodiment, the sample adding component 30 is used to simultaneously add the same biological sample to be tested to the first color block 01, the second color block 02 and the third color block 03 of the first dry chemical test paper 91 under the control of the processor 70; and, the processor 70 is further used to determine the third color block information from the first image and / or the second image of the first dry chemical test paper 91, and calculate the detection result of the third test item corresponding to the third color block 03 based at least on the third color block information. For example, the third color block corresponds to the third test item, and the third test item corresponds to a preset third reaction time T3. When the third reaction time T3 is equal to the first reaction time T1, the processor 70 can determine the third color block information from the first image of the first dry chemical test paper 91, and calculate the detection result of the third test item corresponding to the third color block 03 at least based on the third color block information; when the third reaction time T3 is equal to the second reaction time T2, the processor 70 can determine the third color block information from the second image of the first dry chemical test paper 91, and calculate the detection result of the third test item corresponding to the third color block 03 at least based on the third color block information.

[0215] In some embodiments, the dry chemical detection device may further photograph the dry chemical test strip 90 before adding the biological sample to be tested to determine whether the dry chemical test strip 90 has any abnormalities. Therefore, in some embodiments, the imaging component 50 is further configured to photograph the first dry chemical test strip 91 to obtain a third image before the sample adding component 30 adds the biological sample to be tested to the first color block 01 and the second color block 02 of the first dry chemical test strip 91. The processor 70 is further configured to determine an abnormality of the first dry chemical test strip 91 based on the third image. The abnormality includes at least one of a first and a second type of abnormality. The first type of abnormality indicates that the first dry chemical test strip 91 is unusable, and the second type of abnormality indicates that there is a deviation in the position of at least one color block in the first dry chemical test strip 91.

[0216] In some embodiments, the first type of abnormality may specifically be that at least one color block in the first dry chemical test paper 91 is unusable, including but not limited to the original color of the color block changing due to reasons such as the color block being bent, falling off, or being affected by moisture, all of which may cause abnormalities in subsequent test results.

[0217] In some embodiments, the second type of abnormality may specifically be that the position of the first dry chemical test paper 91 in its width direction is not as expected, the first dry chemical test paper 91 is incorrectly placed, and / or there is a deviation in the position of at least one color block in the first dry chemical test paper 91 in its length direction. The position of the first dry chemical test paper 91 in its width direction is not as expected, which means that the first dry chemical test paper 91 is offset in the width direction in the position of the supporting component 10 or the test paper area 20, etc., which will result in the biological sample to be tested not dripping onto the color block 99 or dripping onto the edge of the color block 99 when adding the biological sample to be tested to the first dry chemical test paper 91. The incorrect placement of the first dry chemical test paper 91 includes but is not limited to being inverted head to tail, etc.; the placement of dry chemical test paper in the length direction is divided into "head to tail", and if the operator accidentally inverts the head to tail when placing the dry chemical test paper, the subsequent test results will naturally be abnormal. There is a deviation in the position of at least one color block in the first dry chemical test paper 91 in the length direction of the first dry chemical test paper 91. The reason for this abnormality may be a defect in the manufacture of the test paper, such as the spacing between adjacent color blocks is too large, or it may be due to the displacement of the first dry chemical test paper 91 along its own length direction on the supporting component 10 or in the test paper area 20.

[0218] The above is some explanation of this application, and the following is some explanation in combination with specific scenarios.

[0219] (1) Global Camera + Dynamic Scene

[0220] In some embodiments, the imaging component 50 includes a global camera 51, and the supporting component 10 includes a conveying assembly 11 and a power mechanism 13; in such an embodiment, the first dry chemical test paper 91 will be conveyed among multiple test paper areas 20, for example, from one test paper area 20 to the next test paper area 20 along a preset direction. When the first dry chemical test paper 91 is conveyed among the at least two test paper areas 20 covered by the shooting field of view of the global camera 51, it can be photographed by the global camera 51 to obtain a first image and a second image. For example, one of the at least two test paper areas 20 is photographed by the global camera 51 to obtain a first image, and another of the at least two test paper areas 20 is photographed by the global camera 51 to obtain a second image.

[0221] Therefore, in some embodiments, the processor 70 determines the first color block information from the first image, including: determining the position of the first dry chemical test paper 91 in the first image based on the second preset period, the first reaction time T1, and the test paper area 20 where the first dry chemical test paper 91 is located when the biological sample to be tested is added; obtaining the position of the first color block 01 on the first dry chemical test paper 91; and determining the first color block information from the first image based on the position of the first dry chemical test paper 91 in the first image and the position of the first color block 01 on the first dry chemical test paper 91.

[0222] Similarly, the processor 70 determines the second color block information from the second image, including: determining the position of the first dry chemical test paper 91 in the second image based on the second preset cycle, the second reaction time T2, and the test paper area 20 where the first dry chemical test paper 91 is located when the biological sample to be tested is added; obtaining the position of the second color block 02 on the first dry chemical test paper 91; and determining the second color block information from the second image based on the position of the first dry chemical test paper 91 in the second image and the position of the second color block 02 on the first dry chemical test paper 91.

[0223] In some embodiments, the global camera 51 periodically photographs the first dry chemical test paper 91 at a first preset period to obtain multiple images; wherein: the first reaction time T1 is the time corresponding to M first preset periods after the first dry chemical test paper 91 is added with the biological sample to be tested, and accordingly, the first image is the image of the first dry chemical test paper 91 obtained by photographing the first dry chemical test paper 91 after the first dry chemical test paper 91 is added with the biological sample to be tested and after M first preset periods; the second reaction time T2 is the time corresponding to N first preset periods after the first dry chemical test paper 91 is added with the biological sample to be tested, and accordingly, the second image is the image of the first dry chemical test paper 91 obtained by photographing the first dry chemical test paper 91 after the first dry chemical test paper 91 is added with the biological sample to be tested and after N first preset periods; M and N are preset positive integers and the two are not equal.

[0224] The test strip area 20 where the first dry chemical test strip 91 is loaded with the biological sample to be tested may be referred to as the sample loading area 21 ( FIG. 3 is an example, where the first test strip area 20 on the left is the sample loading area 21 ). Specifically, the dry chemical testing device includes multiple test strip areas 20, including the sample loading area 21. In some embodiments, the sample loading component 30 simultaneously adds the same biological sample to be tested to the first and second color blocks of the first dry chemical test strip 91 transferred to the sample loading area 21 . In other words, the first and second color blocks of the first dry chemical test strip 91 are loaded with the same biological sample to be tested in the same test strip area 20. In some embodiments, the field of view of the global camera 51 can cover at least two test strip areas 20 following the sample loading area 21 along the predetermined direction. In other words, the field of view of the global camera 51 covers at least two of the multiple test strip areas 20 that the first dry chemical test strip 91 moves from the sample loading area 21 to along the predetermined direction.

[0225] The first color block and the second color block in the first dry chemical test paper 91 are added to the same test paper area 20 with the same biological sample to be tested. After the first reaction time T1, the position of the first dry chemical test paper 91 is determined and can be pre-acquired. After the second reaction time T2, the position of the first dry chemical test paper 91 is also determined and can be pre-acquired. Therefore, in some embodiments, the processor 70 determines the first color block information from the first image, including: using a preset third area in the first image as the position of the first dry chemical test paper 91 in the first image, obtaining the position of the first color block 01 on the first dry chemical test paper 91, and determining the first color block information from the first image based on the position of the first dry chemical test paper 91 in the first image and the position of the first color block 01 on the first dry chemical test paper 91. Similarly, the processor 70 determines the second color block information from the second image, including: using the fourth area preset in the second image as the position of the first dry chemical test paper 91 in the second image, obtaining the position of the second color block 02 on the first dry chemical test paper 91, and determining the second color block information from the second image based on the position of the first dry chemical test paper 91 in the second image and the position of the second color block 02 on the first dry chemical test paper 91.

[0226] (2) Global Camera + Static Scene

[0227] In some embodiments, the imaging component 50 includes a global camera 51, and the dry chemical test paper 90 placed on the supporting component 10 is stationary relative to the imaging component 50; therefore, in some embodiments, the first dry chemical test paper 91 is also stationary and non-moving. That is, when the dry chemical test paper 90 is located in a test paper area 20, the dry chemical test paper 90 will remain in this test paper area 20. Therefore, when the first dry chemical test paper 91 is in any of the at least two test paper areas covered by the shooting field of view of the global camera 51, it can be photographed to obtain a first image and a second image. For example, the first image is captured at one time and the second image is captured at another time. It can be understood that because the first dry chemical test paper 91 is stationary and non-moving on the supporting component 10, the position of the first dry chemical test paper 91 in the first image and the second image is also the same and unchanged.

[0228] Therefore, in some embodiments, the processor 70 determines the first color block information from the first image, including: obtaining the test paper area 20 where the first dry chemical test paper 91 is located; determining the position of the first dry chemical test paper 91 in the first image based on the test paper area 20 where the first dry chemical test paper 91 is located; obtaining the position of the first color block 01 on the first dry chemical test paper 91; and obtaining the first color block information from the first image based on the position of the first dry chemical test paper 91 in the first image and the position of the first color block 01 on the first dry chemical test paper 91.

[0229] Similarly, the processor 70 determines the second color block information from the second image, including: obtaining the test paper area 20 where the first dry chemical test paper 91 is located; determining the position of the first dry chemical test paper 91 in the second image based on the test paper area 20 where the first dry chemical test paper 91 is located; obtaining the position of the second color block 02 on the first dry chemical test paper 91; and determining the second color block information from the second image based on the position of the first dry chemical test paper 91 in the second image and the position of the second color block 02 on the first dry chemical test paper 91.

[0230] In some embodiments, the global camera 51 periodically photographs the first dry chemical test paper 91 at a first preset period to obtain multiple images; wherein: the first reaction time T1 is the time corresponding to M first preset periods after the first dry chemical test paper 91 is added with the biological sample to be tested, and accordingly, the first image is the image of the first dry chemical test paper 91 obtained by photographing the first dry chemical test paper 91 after the first dry chemical test paper 91 is added with the biological sample to be tested and after M first preset periods; the second reaction time T2 is the time corresponding to N first preset periods after the first dry chemical test paper 91 is added with the biological sample to be tested, and accordingly, the second image is the image of the first dry chemical test paper 91 obtained by photographing the first dry chemical test paper 91 after the first dry chemical test paper 91 is added with the biological sample to be tested and after N first preset periods; M and N are preset positive integers and the two are not equal.

[0231] In addition, in the case of (1) global camera + dynamic scene, or (2) global camera + static scene, the position of the first dry chemical test paper 91 in the image can also be determined by the test paper identification, thereby finally determining the first color block information and the second color block information. Therefore, in some embodiments, the first dry chemical test paper 91 has a test paper identification, which can be determined by image recognition to distinguish different dry chemical test papers; the processor 70 determines the first color block information from the first image, including: determining the position of the first dry chemical test paper 91 in the first image based on the test paper identification of the first dry chemical test paper 91; obtaining the position of the first color block 01 on the first dry chemical test paper 91; determining the first color block information from the first image based on the position of the first dry chemical test paper 91 in the first image and the position of the first color block 01 on the first dry chemical test paper 91; similarly, the processor 70 determines the second color block information from the second image, including: determining the position of the first dry chemical test paper 91 in the second image based on the test paper identification of the first dry chemical test paper 91; obtaining the position of the second color block 02 on the first dry chemical test paper 91; determining the second color block information from the second image based on the position of the first dry chemical test paper 91 in the second image and the position of the second color block on the first dry chemical test paper 91.

[0232] (3) Local camera + dynamic scene

[0233] In some embodiments, the imaging component 50 includes at least two local cameras 53, and the supporting component 10 includes a conveying assembly 11 and a power mechanism 13; in such an embodiment, the first dry chemical test paper 91 will be conveyed among multiple test paper areas 20, for example, from one test paper area 20 to the next test paper area 20 along a preset direction, so that when the first dry chemical test paper 91 is conveyed between the test paper areas 20 corresponding to the shooting field of each local camera 53, it can be photographed by the corresponding local camera 53 to obtain a first image and a second image.

[0234] Therefore, in some embodiments, the processor 70 determines the first color block information from the first image, including: determining the first test paper area 20 of the first dry chemical test paper 91 in the test paper area 20 when the biological sample to be tested is added and the first reaction time T1 has passed based on the second preset period, the first reaction time T1, and the test paper area 20 where the first dry chemical test paper 91 is located when the biological sample to be tested is added; determining the first local camera 53 from the at least two local cameras 53 included in the imaging component 50 based on the first test paper area 20; obtaining the image taken by the first local camera 53 on the first dry chemical test paper 91 after the biological sample to be tested is added and the first reaction time T1 has passed as the first image; and determining the first color block information from the first image based on the position of the first color block 01 on the first dry chemical test paper 91.

[0235] Similarly, the processor 70 determines the second color block information from the second image, including: determining the second test paper area 20 of the first dry chemical test paper 91 in the test paper area 20 after the biological sample to be tested is added to the first dry chemical test paper 91 and the second reaction time T2 has passed, based on the second preset period, the second reaction time T2, and the test paper area 20 where the first dry chemical test paper 91 is located when the biological sample to be tested is added; determining the second local camera 53 from the at least two local cameras 53 included in the imaging component 50 based on the second test paper area 20; obtaining the image taken by the second local camera 53 on the first dry chemical test paper 91 after the biological sample to be tested is added and the second reaction time T2 has passed as the second image; and determining the second color block information of the second color block 02 from the second image according to the position of the second color block 02 on the first dry chemical test paper 91.

[0236] In some embodiments, each local camera 53 synchronously and periodically photographs the dry chemical test paper in the test paper area corresponding to its respective shooting field of view at a first preset period; wherein: the first reaction time T1 is the time corresponding to M first preset periods after the first dry chemical test paper 91 is added with the biological sample to be tested, and accordingly, the first image is the image of the first dry chemical test paper 91 obtained by photographing the first dry chemical test paper 91 after the biological sample to be tested is added and after M first preset periods - it can be understood that here refers to the image obtained by one of the local cameras 53 on the first dry chemical test paper 91 after the biological sample to be tested is added and after M first preset periods. The second reaction time T2 is the time length corresponding to N first preset cycles after the biological sample to be tested is added to the first dry chemical test paper 91. Accordingly, the second image is the image of the first dry chemical test paper 91 obtained by taking the first dry chemical test paper 91 after the biological sample to be tested is added and after N first preset cycles; M and N are preset positive integers and the two are not equal - it can be understood that here it refers to the image of the first dry chemical test paper 91 obtained by one of the local cameras 53 on the first dry chemical test paper 91 after the biological sample to be tested is added and after M first preset cycles.

[0237] The test paper area 20 where the first dry chemical test paper 91 is loaded with the biological sample to be tested may be referred to as the sample loading area 21. That is, the dry chemical testing device includes multiple test paper areas 20, including the sample loading area 21. In some embodiments, the sample loading component 30 simultaneously adds the same biological sample to be tested to the first and second color blocks of the first dry chemical test paper 91 transferred to the sample loading area 21. That is, the first and second color blocks of the first dry chemical test paper 91 are loaded with the same biological sample to be tested in the same test paper area 20. In some embodiments, the test paper area 20 corresponding to the field of view of each local camera 53 includes at least the test paper area 20 following the sample loading area 21 along the preset direction. In other words, the first dry chemical test paper 91 moves from the sample loading area 21 to the multiple test paper areas 20 in sequence along the preset direction. At least two of the multiple test paper areas 20 correspond to respective local cameras 53.

[0238] The first color block and the second color block in the first dry chemical test paper 91 are added with the same biological sample to be tested in the same test paper area 20. After the first reaction time T1, the position of the first dry chemical test paper 91 is determined and can be pre-acquired. Therefore, the position or the local camera 53 corresponding to the test paper area 20 where the position is located is also determined and can be pre-acquired; similarly, the first color block and the second color block in the first dry chemical test paper 91 are added with the same biological sample to be tested in the same test paper area 20. After the second reaction time T2, the position of the first dry chemical test paper 91 is determined and can be pre-acquired. Therefore, the position or the local camera 53 corresponding to the test paper area 20 where the position is located is also determined and can be pre-acquired. Therefore, in some embodiments, the processor 70 determines the first color block information from the first image by: acquiring the first local camera 53 corresponding to the first color block 01, wherein the correspondence between the first local camera 53 and the first color block 01 is pre-established; acquiring an image captured by the first local camera 53 after the biological sample to be tested is added to the first dry chemical test strip 91 and a first reaction time T1 is elapsed as the first image; and determining the first color block information of the first color block 01 from the first image based on the position of the first color block 01 on the first dry chemical test strip 91. Similarly, the processor 70 determines the second color block information from the second image by: acquiring the second local camera 53 corresponding to the second color block 02, wherein the correspondence between the second local camera 53 and the second color block 02 is pre-established; acquiring an image captured by the second local camera 53 after the biological sample to be tested is added to the first dry chemical test strip 91 and a second reaction time T2 is elapsed as the second image; and determining the second color block information of the second color block 02 from the second image based on the position of the second color block 02 on the first dry chemical test strip 91.

[0239] (4) Local camera + static scene

[0240] In some embodiments, the imaging component 50 includes at least two local cameras 53, and the dry chemical test paper 90 placed on the supporting component 10 is stationary relative to the imaging component 50. Therefore, in some embodiments, the first dry chemical test paper 91 is also stationary and non-moving. That is, when the dry chemical test paper 90 is located in a test paper area 20, the dry chemical test paper 90 will remain in this test paper area 20. Therefore, when the first dry chemical test paper 91 is in the test paper area 20 corresponding to the shooting field of view of any local camera 53, it can be photographed by the corresponding local camera 53 to obtain a first image and a second image. For example, the same local camera 53 can be used to capture the first image at one time and the second image at another time.

[0241] Therefore, in some embodiments, the processor 70 determines the first color block information from the first image by: acquiring the test paper area 20 where the first dry chemical test paper 91 is located; determining a target local camera 53 from the at least two local cameras 53 included in the imaging component 50 based on the test paper area 20 where the first dry chemical test paper 91 is located; acquiring as the first image an image captured by the target local camera 53 after the biological sample to be tested is added to the first dry chemical test paper 91 and a first reaction time T1 elapses; and determining, from the first image, first color block information of the first color block 01 based on the position of the first color block 01 on the first dry chemical test paper 91. Similarly, the processor 70 determines the second color block information from the second image by: acquiring as the second image an image captured by the target local camera 53 after the biological sample to be tested is added to the first dry chemical test paper 91 and a second reaction time T2 elapses; and determining, from the second image, second color block information of the second color block 02 based on the position of the second color block 02 on the first dry chemical test paper 91.

[0242] In some embodiments, each local camera 53 synchronously and periodically photographs the dry chemical test paper in the test paper area corresponding to its respective shooting field of view in a first preset cycle; wherein: the first reaction time T1 is the time corresponding to M first preset cycles after the biological sample to be tested is added to the first dry chemical test paper 91, and accordingly, the first image is the image of the first dry chemical test paper 91 obtained by photographing the first dry chemical test paper 91 after the biological sample to be tested is added and after M first preset cycles - it can be understood that here refers to the image obtained by one of the local cameras 53 (the local camera 53 corresponding to the test paper area 20 where the first dry chemical test paper 91 is located) after the biological sample to be tested is added and after M first preset cycles. The second reaction time T2 is the time length corresponding to N first preset cycles after the biological sample to be tested is added to the first dry chemical test paper 91. Accordingly, the second image is the image of the first dry chemical test paper 91 obtained by taking the first dry chemical test paper 91 after the biological sample to be tested is added and after N first preset cycles; M and N are preset positive integers and are not equal - it can be understood that here it refers to the image of the first dry chemical test paper 91 obtained by one of the local cameras 53 (the local camera 53 corresponding to the test paper area 20 where the first dry chemical test paper 91 is located) after the biological sample to be tested is added to the first dry chemical test paper 91 and after M first preset cycles.

[0243] The above descriptions of the present application are based on specific scenarios. In a dynamic scenario, the first reaction time T1 and the second reaction time T2 can also be calibrated by the test paper area 20 to which the first dry chemical test paper 91 is delivered.

[0244] Therefore, in some embodiments, please refer to Figure 6, the dry chemical detection device includes multiple test paper areas 20, which include a first reaction end area 29a preset for the first test item, and a second reaction end area 29b preset for the second test item and different from the first reaction end area 29a; the sample adding component 30, under the control of the processor 70, simultaneously adds the same biological sample to be tested to the first color block 01 and the second color block 02 of the first dry chemical test paper 91; the driving component 10a is used to drive the carrying component 10 so that the first dry chemical test paper 91 after the biological sample to be tested is added is rotated according to the first color block 01 and the second color block 02. The first reaction end area 29a0 and the second reaction end area 29b are reached at the same time. The imaging component 50 is used to photograph the first dry chemical test paper 91 after the sample adding component 30 adds the same biological sample to be tested to the first color block 01 and the second color block 02 of the first dry chemical test paper 91 to obtain multiple images. The multiple images include at least a first image and a second image. The first image is an image of the first dry chemical test paper 91 photographed in the first reaction end area 29a, and the second image is an image of the first dry chemical test paper 91 photographed in the second reaction end area 29b. The processor 70 determines the first color block information from the first image and calculates the test result of the first test item corresponding to the first color block 01 based on at least the first color block information. The processor 70 also determines the second color block information from the second image and calculates the test result of the second test item corresponding to the second color block 02 based on at least the second color block information.

[0245] In some embodiments, the imaging component 50 includes a global camera 51 , and the shooting field of the global camera 51 can cover the first reaction end area 29 a and the second reaction end area 29 b .

[0246] In some embodiments, the imaging component 50 includes at least a first local camera 53 and a second local camera 53 , wherein the shooting field of the first local camera 53 is the first reaction end area 29 a , and the shooting field of the second local camera 53 is the second reaction end area 29 b .

[0247] In addition, it can be understood that the driving component 10a and the carrying component 10 are two components divided according to the functions they implement, which implement the dynamic scene referred to in this article. The driving component 10a and the carrying component 10 can also be divided into the same component. Under this division, the carrying component 10 includes the above-mentioned conveying component 11 and the power mechanism 13. Therefore, the conveying component 11 is driven by the power mechanism 13 to convey the dry chemical test paper 90 thereon along a preset direction to drive the dry chemical test paper 90 to be conveyed along the preset direction in the multiple test paper areas 20 included in the dry chemical detection device. Various descriptions are also applicable to describing the driving component 10a driving the carrying component 10 so that the dry chemical test paper 90 carried by the carrying component 10 is conveyed in multiple test paper areas 20.

[0248] The above describes some of the present application in conjunction with specific scenarios. In particular, in the global camera scenario, since the shooting field of view of the global camera 51 can cover at least two test paper areas 20, the image captured by the global camera 51 at the same time can include multiple dry chemical test strips 90, so that the test results of the test items corresponding to one or more color blocks in different dry chemical test strips 90 can be obtained in the same image.

[0249] For example, in addition to the first dry chemical test paper 91, the dry chemical test paper 90 also includes a second dry chemical test paper 92, and the second dry chemical test paper 92 has at least a fourth color block 04 corresponding to the fourth test item, wherein the fourth test item corresponds to a preset fourth reaction time; the first image or the second image also has the second dry chemical test paper 92; the processor 70 also determines the fourth color block information based on the first image or the second image, and calculates the detection result of the fourth test item corresponding to the fourth color block 04 based on at least the fourth color block information. For example, the color blocks of the first dry chemical test paper 91 are added to the sample adding area 21 at time 0, and the color blocks of the second dry chemical test paper 92 are added to the sample adding area 21 at time 10s. The second reaction time T2 of the second color block 02 of the first dry chemical test paper 91 is 10s longer than the second reaction time T4 of the fourth color block 04 of the second dry chemical test paper 92. Thus, the second image contains the first dried test paper and the second dried test paper, and since the second image is taken after the second color block 02 of the first dry chemical test paper 91 is added to the biological sample to be tested and after the second reaction time T2, At this time, the fourth color block 04 of the second dry chemical test paper 92 is added with the biological sample to be tested and experiences the fourth reaction time T4. Therefore, in the second image, the second color block 02 of the first dried test paper and the fourth color block 04 of the second dried test paper have both reached their respective reaction times, so that the processor 70 can determine the second color block information of the second color block 02 and the fourth color block information of the fourth color block 04 based on the second image, and calculate the detection result of the second test item corresponding to the second color block 02 based on the second color block information, and calculate the detection result of the fourth test item corresponding to the fourth color block 04 based on the fourth color block information.

[0250] It should be noted that the serial numbers assigned to the color blocks herein, such as "first," "second," "third," and "fourth," are used solely to distinguish the objects being described and do not convey any sequential or technical meaning. The fact that the second dry chemical test paper 92 has a fourth color block 04 does not necessarily mean that the second dry chemical test paper 92 also has a first color block 01, a second color block 02, and a third color block 03. The fact that the second dry chemical test paper 92 has a fourth color block 04 herein refers to a color block 99 on the second dry chemical test paper 92, and is numbered fourth color block 04 to distinguish it from the first color block 01, the second color block 02, and the third color block 03 of the first dry chemical test paper 91 described previously.

[0251] In some embodiments, the dry chemical detection device can also provide multiple processing modes. For example, as described above, the first dry chemical test paper 91 has at least two color blocks 99, each color block 99 corresponding to a test item; the sample adding component 30 is used to simultaneously add the same biological sample to be tested to the at least two color blocks 99 of the first dry chemical test paper 91 under the control of the processor 70; the imaging component 50 is used to photograph the first dry chemical test paper 91 after the sample adding component 30 adds the same biological sample to be tested to the at least two color blocks 99 of the first dry chemical test paper 91 to obtain multiple images; the processor 70 has a first processing mode and a second processing mode; in the first processing mode: the processor 70 0 selects a target image from the multiple images, and obtains the detection results of the test items corresponding to the at least two color blocks 99 in the first dry chemical test paper 91 based on the target image; in the second processing mode: the processor 70 selects at least two target images from the multiple images, and obtains the detection results of the test items corresponding to the at least two color blocks 99 in the first dry chemical test paper 91 based on the at least two target images, for example, the detection result of the test item corresponding to one color block 99 in the first dry chemical test paper 91 is obtained from one of the target images, and the detection result of the test item corresponding to another color block 99 in the first dry chemical test paper 91 is obtained from the other target image.

[0252] The above describes an example in which the sample adding component 30, under the control of the processor 70, simultaneously adds the same biological sample to be tested to various color blocks of a dry chemical test paper 90, such as the first color block 01 and the second color block 02 of the first dry chemical test paper 91; the first color block 01 and the second color block 02 of the first dry chemical test paper 91 can also be added at different times, which is explained in detail below.

[0253] In some embodiments, referring to FIG. 7 , the test paper area 20 includes a preset identical reaction end area 29 c for the first test item and the second test item; or, the first test item and the second test item are preset with the same reaction end time. In some embodiments, the sample loading component 30 is configured to add the biological sample to be tested to the first color block 01 on the first dry chemical test paper 91 at a first sample loading time, and to add the biological sample to be tested to the second color block 02 on the first dry chemical test paper 91 at a second sample loading time different from the first sample loading time; or, the test paper area 20 includes a first sample loading area 21 a and a second sample loading area 21 b different from the first sample loading area 21 a, and the sample loading component 30 is configured to add the biological sample to be tested to the first color block 01 on the first dry chemical test paper 91 at the first sample loading area 21 a, and to add the biological sample to be tested to the second color block 02 on the first dry chemical test paper 91 at the second sample loading area 21 b. The imaging component 50 is used to capture an image of the first dry chemical test paper 91 after the biological sample to be tested is added; the processor 70 is used to calculate the detection results of the first test item and the detection results of the second test item based on the image captured by the first dry chemical test paper 91 in the above-mentioned same reaction end area or at the above-mentioned same reaction end time after the biological sample to be tested is added.

[0254] Sample loading can be accomplished by two independent sample loading mechanisms 31, such as a first sample loading mechanism 31 and a second sample loading mechanism 31. In some embodiments, the first sample loading mechanism 31 is used to add the biological sample to be tested to the first color block 01 on the first dry chemical test paper 91 at a first sample loading moment, and the second sample loading mechanism 31 is used to add the biological sample to be tested to the second color block 02 on the first dry chemical test paper 91 at a second sample loading moment. In some embodiments, in a dynamic scenario, the first sample loading mechanism 31 is used to add the biological sample to be tested to the first color block 01 on the first dry chemical test paper 91 when the first dry chemical test paper 91 reaches the first sample loading area 21a; and the second sample loading mechanism 31 is used to add the biological sample to be tested to the second color block on the first dry chemical test paper 91 when the first dry chemical test paper 91 reaches the second sample loading area 21b.

[0255] Sample loading can also be accomplished by a sample loading mechanism 31. In some embodiments, the sample loading mechanism 31 is used to add the biological sample to be tested to the first color block 01 on the first dry chemical test paper 91 at a first sample loading moment, and to add the biological sample to be tested to the second color block 02 on the first dry chemical test paper 91 at a second sample loading moment. In some embodiments, in a dynamic scenario, the sample loading mechanism 31 is capable of moving relative to the test paper area 20 so as to add the biological sample to be tested to the first color block 01 on the first dry chemical test paper 91 when the first dry chemical test paper 91 reaches the first sample loading area 21a, and to add the biological sample to be tested to the second color block on the first dry chemical test paper 91 when the first dry chemical test paper 91 reaches the second sample loading area 21b.

[0256] In some embodiments of the present application, a dry chemical detection method is also disclosed. In some embodiments, the dry chemical detection method of the present application can be applied to the dry chemical detection device disclosed in the present application.

[0257] Referring to FIG. 8 , the dry chemical detection method of some embodiments includes the following steps:

[0258] Step 100: Adding a biological sample to be tested to color block 99 of dry chemical test paper 90 located in test paper area 20 via sample adding component 30; dry chemical test paper 90 includes first dry chemical test paper 91, which has at least a first color block 01 corresponding to a first test item and a second color block 02 corresponding to a second test item, wherein the first test item corresponds to a preset first reaction time T1, and the second test item corresponds to a preset second reaction time T2 that is different from the first reaction time T1. Therefore, step 100 of adding a biological sample to be tested to color block 99 of dry chemical test paper 90 located in test paper area 20 via sample adding component 30 includes: simultaneously adding the same biological sample to first color block 01 and second color block 02 of first dry chemical test paper 91.

[0259] Step 200: After the biological sample to be tested is added to the first color block 01 and the second color block 02 of the first dry chemical test paper 91 by the imaging component 50, the first dry chemical test paper 91 is photographed to obtain multiple images; wherein, the multiple images include at least a first image and a second image, the first image is an image of the first dry chemical test paper 91 obtained by photographing the first dry chemical test paper 91 after the biological sample to be tested is added and a first reaction time T1 has passed, and the second image is an image of the first dry chemical test paper 91 obtained by photographing the first dry chemical test paper 91 after the biological sample to be tested is added and a second reaction time T2 has passed.

[0260] In some embodiments, step 200 periodically photographs the first dry chemical test paper 91 at a first preset period through the imaging component to obtain the multiple images; wherein: the first reaction time T1 is the time corresponding to M first preset periods after the first dry chemical test paper 91 is added with the biological sample to be tested, and accordingly, the first image is the image of the first dry chemical test paper 91 obtained by photographing the first dry chemical test paper 91 after the first dry chemical test paper 91 is added with the biological sample to be tested and after M first preset periods; the second reaction time T2 is the time corresponding to N first preset periods after the first dry chemical test paper 91 is added with the biological sample to be tested, and accordingly, the second image is the image of the first dry chemical test paper 91 obtained by photographing the first dry chemical test paper 91 after the first dry chemical test paper 91 is added with the biological sample to be tested and after N first preset periods; M and N are preset positive integers and the two are not equal.

[0261] Step 300: Determine first color block information from the first image, and calculate the detection result of the first test item corresponding to the first color block 01 based on at least the first color block information, and determine second color block information from the second image, and calculate the detection result of the second test item corresponding to the second color block 02 based on at least the second color block information.

[0262] In some embodiments, the reaction time can also be associated with the position. Therefore, in some embodiments, step 300 determines the first color block information from the first image, including: using the image information located in the preset first area of ​​the first image as the first color block information, the preset first area corresponding to the first color block 01 of the first dry chemical test paper 91; step 300 determines the second color block information from the second image, including: using the image information located in the preset second area of ​​the second image as the second color block information, the preset second area corresponding to the second color block 02 of the first dry chemical test paper 91. In some embodiments, before determining the first color block information from the first image and determining the second color block information from the second image, step 300 also includes: obtaining the test paper type of the first dry chemical test paper 91; and obtaining the above-mentioned preset first area and the above-mentioned preset second area based on the test paper type of the first dry chemical test paper 91.

[0263] In some embodiments, the first dry chemical test paper 91 further has a third color block 03 corresponding to a third test item; in such an embodiment, step 100 simultaneously adds the same biological sample to be tested to the first color block 01, the second color block 02 and the third color block 03 of the first dry chemical test paper 91 through the sample adding component 30; and step 300 is also used to determine the third color block information from the first image and / or the second image of the first dry chemical test paper 91, and calculate the detection result of the third test item corresponding to the third color block 03 based at least on the third color block information.

[0264] In some embodiments, the dry chemical detection method further includes step one: photographing the first dry chemical test paper 91 by the imaging component 50 before the sample adding component 30 adds the biological sample to be tested to the first color block 01 and the second color block 02 of the first dry chemical test paper 91 to obtain a third image; and judging the first dry chemical test paper 91 for abnormalities based on the third image, the abnormalities include at least one of the first and second types of abnormalities; the first type of abnormality is used to characterize that the first dry chemical test paper 91 is unusable, and the second type of abnormality is used to characterize that there is a deviation in the position of at least one color block in the first dry chemical test paper 91.

[0265] In some embodiments, there are multiple test strip areas 20, and the imaging component 50 includes a global camera 51. The global camera 51 has a field of view that covers at least two of the multiple test strip areas 20. The global camera 51 is used to capture the dry chemical test strips 90 located in the at least two test strip areas. In some embodiments, the field of view of the global camera 51 can cover all of the test strip areas 20.

[0266] In some embodiments, referring to FIG. 9 , the dry chemical detection method further includes step 110: driving the carrying component 10 by the driving component 10a so that the dry chemical test paper 90 placed on the carrying component 10 is periodically transported in a plurality of test paper areas 20 along a preset direction at a second preset period, so that when the first dry chemical test paper 91 is transported in the at least two test paper areas 20 covered by the shooting field of view of the global camera 51, it can be photographed by the global camera 51 to obtain the first image and the second image; for example, the first dry chemical test paper 91 will be in the plurality of test paper areas The first dry chemical test paper 91 is transmitted in the at least two test paper areas 20 covered by the shooting field of view of the global camera 51, for example, it is transmitted from one test paper area 20 to the next test paper area 20 along a preset direction. When the first dry chemical test paper 91 is transmitted in the at least two test paper areas 20 covered by the shooting field of view of the global camera 51, it can be photographed by the global camera 51 to obtain a first image and a second image. For example, one of the at least two test paper areas 20 is photographed by the global camera 51 to obtain a first image, and the other test paper area 20 in the at least two test paper areas 20 is photographed by the global camera 51 to obtain a second image.

[0267] In some embodiments, referring to FIG. 10( a ), step 300 of determining first color block information from a first image includes the following steps:

[0268] Step 301 : Determine the position of the first dry chemical test paper 91 in the first image according to the second preset period, the first reaction time T1 and the test paper area 20 where the first dry chemical test paper 91 is located when the biological sample to be tested is added.

[0269] Step 302 : Obtain the position of the first color block 01 on the first dry chemical test paper 91 .

[0270] Step 303 : determining first color block information from the first image according to the position of the first dry chemical test paper 91 in the first image and the position of the first color block 01 on the first dry chemical test paper 91 .

[0271] Similarly, referring to FIG. 10( b ), step 300 of determining the second color block information from the second image includes the following steps:

[0272] Step 304 : Determine the position of the first dry chemical test paper 91 in the second image according to the second preset period, the second reaction time T2 and the test paper area 20 where the first dry chemical test paper 91 is located when the biological sample to be tested is added.

[0273] Step 305 : Obtain the position of the second color block 02 on the first dry chemical test paper 91 .

[0274] Step 306 : Determine the second color block information from the second image according to the position of the first dry chemical test paper 91 in the second image and the position of the second color block 02 on the first dry chemical test paper 91 .

[0275] In some embodiments, the global camera 51 periodically photographs the first dry chemical test paper 91 at a first preset period to obtain multiple images; wherein: the first reaction time T1 is the time corresponding to M first preset periods after the first dry chemical test paper 91 is added with the biological sample to be tested, and accordingly, the first image is the image of the first dry chemical test paper 91 obtained by photographing the first dry chemical test paper 91 after the first dry chemical test paper 91 is added with the biological sample to be tested and after M first preset periods; the second reaction time T2 is the time corresponding to N first preset periods after the first dry chemical test paper 91 is added with the biological sample to be tested, and accordingly, the second image is the image of the first dry chemical test paper 91 obtained by photographing the first dry chemical test paper 91 after the first dry chemical test paper 91 is added with the biological sample to be tested and after N first preset periods; M and N are preset positive integers and the two are not equal.

[0276] The test strip area 20 where the first dry chemical test strip 91 is loaded with the biological sample to be tested may be referred to as the sample loading area 21 ( FIG. 3 is an example, where the first test strip area 20 on the left is the sample loading area 21 ). Specifically, the dry chemical testing device includes multiple test strip areas 20, including the sample loading area 21. In some embodiments, step 100 simultaneously adds the same biological sample to be tested to the first and second color blocks of the first dry chemical test strip 91 transferred to the sample loading area 21 via the sample loading component 30. Specifically, the first and second color blocks of the first dry chemical test strip 91 are loaded with the same biological sample to be tested in the same test strip area 20. In some embodiments, the field of view of the global camera 51 can cover at least two test strip areas 20 following the sample loading area 21 along the predetermined direction. In other words, the field of view of the global camera 51 covers at least two of the multiple test strip areas 20 that the first dry chemical test strip 91 moves from the sample loading area 21 to along the predetermined direction.

[0277] The first color block and the second color block in the first dry chemical test paper 91 are added to the same test paper area 20 with the same biological sample to be tested. After the first reaction time T1, the position of the first dry chemical test paper 91 is determined and can be pre-acquired. After the second reaction time T2, the position of the first dry chemical test paper 91 is also determined and can be pre-acquired. Therefore, in some embodiments, step 300 determines the first color block information from the first image, including: using a preset third area in the first image as the position of the first dry chemical test paper 91 in the first image, obtaining the position of the first color block 01 on the first dry chemical test paper 91, and determining the first color block information from the first image based on the position of the first dry chemical test paper 91 in the first image and the position of the first color block 01 on the first dry chemical test paper 91. Similarly, step 300 determines the second color block information from the second image, including: using the fourth area preset in the second image as the position of the first dry chemical test paper 91 in the second image, obtaining the position of the second color block 02 on the first dry chemical test paper 91, and determining the second color block information from the second image based on the position of the first dry chemical test paper 91 in the second image and the position of the second color block 02 on the first dry chemical test paper 91.

[0278] In some embodiments, the imaging component 50 includes a global camera 51, and the dry chemical test paper 90 placed on the supporting component 10 is stationary relative to the imaging component 50; therefore, in some embodiments, the first dry chemical test paper 91 is also stationary and non-moving. That is, when the dry chemical test paper 90 is located in a test paper area 20, the dry chemical test paper 90 will remain in this test paper area 20. Therefore, when the first dry chemical test paper 91 is in any of the at least two test paper areas covered by the shooting field of view of the global camera 51, it can be photographed to obtain a first image and a second image. For example, the first image is captured at one time and the second image is captured at another time. It can be understood that because the first dry chemical test paper 91 is stationary and non-moving on the supporting component 10, the position of the first dry chemical test paper 91 in the first image and the second image is also the same and unchanged. Therefore, in some embodiments, step 300 of determining the first color block information from the first image includes: obtaining the test paper area 20 where the first dry chemical test paper 91 is located; determining the position of the first dry chemical test paper 91 in the first image based on the test paper area 20 where the first dry chemical test paper 91 is located; obtaining the position of the first color block 01 on the first dry chemical test paper 91; and obtaining the first color block information from the first image based on the position of the first dry chemical test paper 91 in the first image and the position of the first color block 01 on the first dry chemical test paper 91. Similarly, step 300 of determining the second color block information from the second image includes: obtaining the test paper area 20 where the first dry chemical test paper 91 is located; determining the position of the first dry chemical test paper 91 in the second image based on the test paper area 20 where the first dry chemical test paper 91 is located; obtaining the position of the second color block 02 on the first dry chemical test paper 91; and determining the second color block information from the second image based on the position of the first dry chemical test paper 91 in the second image and the position of the second color block 02 on the first dry chemical test paper 91.

[0279] In addition, in the example where the imaging component 50 includes the global camera 51 , the position of the first dry chemical test paper 91 in the image can also be determined by the test paper identifier, thereby ultimately determining the first color block information and the second color block information. Therefore, in some embodiments, the first dry chemical test paper 91 has a test paper identification, which can be determined by image recognition to distinguish different dry chemical test papers; step 300 determines the first color block information from the first image, including: determining the position of the first dry chemical test paper 91 in the first image based on the test paper identification of the first dry chemical test paper 91; obtaining the position of the first color block 01 on the first dry chemical test paper 91; determining the first color block information from the first image based on the position of the first dry chemical test paper 91 in the first image and the position of the first color block 01 on the first dry chemical test paper 91; similarly, step 300 determines the second color block information from the second image, including: determining the position of the first dry chemical test paper 91 in the second image based on the test paper identification of the first dry chemical test paper 91; obtaining the position of the second color block 02 on the first dry chemical test paper 91; determining the second color block information from the second image based on the position of the first dry chemical test paper 91 in the second image and the position of the second color block on the first dry chemical test paper 91.

[0280] In some embodiments, there are multiple test paper areas 20, and the imaging component 50 includes multiple local cameras 53, for example, at least two local cameras 53. The field of view of each local camera 53 is one of the multiple test paper areas 20, and different local cameras 53 have different test paper areas 20 corresponding to their respective fields of view. Each local camera 53 is used to capture the dry chemical test paper 90 in the test paper area 20 corresponding to its respective field of view. In some embodiments, the number of local cameras 53 is the same as the number of test paper areas 20 included in the dry chemical testing device, that is, each test paper area 20 corresponds to one local camera 53.

[0281] In some embodiments, please refer to Figure 11, the dry chemical detection method also includes step 111: driving the carrying component 10 by the driving component 10a so that the dry chemical test paper 90 placed on the carrying component 10 is periodically transported in multiple test paper areas 20 along a preset direction with a second preset period, so that when the first dry chemical test paper 91 is transported between the test paper areas 20 corresponding to the shooting field of each local camera 53, it can be photographed by the corresponding local camera 53 to obtain the first image and the second image; for example, the first dry chemical test paper 91 will be transported in multiple test paper areas 20, for example, from one test paper area 20 to the next test paper area 20 along a preset direction, so that when the first dry chemical test paper 91 is transported between the test paper areas 20 corresponding to the shooting field of each local camera 53, it can be photographed by the corresponding local camera 53 to obtain the first image and the second image.

[0282] In some embodiments, referring to FIG. 12( a ), step 300 of determining first color block information from a first image includes the following steps:

[0283] Step 311: Determine the first test paper area 20 in which the first dry chemical test paper 91 is located when the biological sample to be tested is added and the first reaction time T1 has elapsed, based on the second preset period, the first reaction time T1, and the test paper area 20 where the first dry chemical test paper 91 is located when the biological sample to be tested is added.

[0284] Step 312 : Determine a first local camera 53 from the at least two local cameras 53 included in the imaging component 50 according to the first test paper area 20 .

[0285] Step 313 : Acquire an image captured by the first local camera 53 when the biological sample to be tested is added to the first dry chemical test paper 91 and after the first reaction time T1 as the first image.

[0286] Step 314 : Determine the first color block information from the first image according to the position of the first color block 01 on the first dry chemical test paper 91 .

[0287] Similarly, referring to FIG. 12( b ), step 300 of determining the second color block information from the second image includes the following steps:

[0288] Step 315: Determine the second test paper area 20 where the first dry chemical test paper 91 is located in the test paper area 20 after the biological sample to be tested is added and the second reaction time T2 has elapsed, based on the second preset cycle, the second reaction time T2, and the test paper area 20 where the first dry chemical test paper 91 is located when the biological sample to be tested is added.

[0289] Step 316 : Determine a second local camera 53 from the at least two local cameras 53 included in the imaging component 50 according to the second test paper area 20 .

[0290] Step 317 : Acquire an image captured by the second local camera 53 after the biological sample to be tested is added to the first dry chemical test paper 91 and after the second reaction time T2 as the second image.

[0291] Step 318 : Determine the second color block information of the second color block 02 from the second image according to the position of the second color block 02 on the first dry chemical test paper 91 .

[0292] In some embodiments, each local camera 53 synchronously and periodically photographs the dry chemical test paper in the test paper area corresponding to its respective shooting field of view at a first preset period; wherein: the first reaction time T1 is the time corresponding to M first preset periods after the first dry chemical test paper 91 is added with the biological sample to be tested, and accordingly, the first image is the image of the first dry chemical test paper 91 obtained by photographing the first dry chemical test paper 91 after the biological sample to be tested is added and after M first preset periods - it can be understood that here refers to the image obtained by one of the local cameras 53 on the first dry chemical test paper 91 after the biological sample to be tested is added and after M first preset periods. The second reaction time T2 is the time length corresponding to N first preset cycles after the biological sample to be tested is added to the first dry chemical test paper 91. Accordingly, the second image is the image of the first dry chemical test paper 91 obtained by taking the first dry chemical test paper 91 after the biological sample to be tested is added and after N first preset cycles; M and N are preset positive integers and the two are not equal - it can be understood that here it refers to the image of the first dry chemical test paper 91 obtained by one of the local cameras 53 on the first dry chemical test paper 91 after the biological sample to be tested is added and after M first preset cycles.

[0293] The test paper area 20 where the first dry chemical test paper 91 is loaded with the biological sample to be tested may be referred to as the sample loading area 21. That is, the dry chemical testing device includes multiple test paper areas 20, including the sample loading area 21. In some embodiments, step 100 simultaneously adds the same biological sample to be tested to the first and second color blocks of the first dry chemical test paper 91 transferred to the sample loading area 21 via the sample loading component 30. That is, the first and second color blocks of the first dry chemical test paper 91 are loaded with the same biological sample to be tested in the same test paper area 20. In some embodiments, the test paper area 20 corresponding to the field of view of each local camera 53 includes at least the test paper area 20 following the sample loading area 21 along the preset direction. In other words, the first dry chemical test paper 91 moves from the sample loading area 21 to the multiple test paper areas 20 in sequence along the preset direction. At least two of the multiple test paper areas 20 correspond to respective local cameras 53.

[0294] The first color block and the second color block in the first dry chemical test paper 91 are added with the same biological sample to be tested in the same test paper area 20. After the first reaction time T1, the position of the first dry chemical test paper 91 is determined and can be pre-acquired. Therefore, the position or the local camera 53 corresponding to the test paper area 20 where the position is located is also determined and can be pre-acquired; similarly, the first color block and the second color block in the first dry chemical test paper 91 are added with the same biological sample to be tested in the same test paper area 20. After the second reaction time T2, the position of the first dry chemical test paper 91 is determined and can be pre-acquired. Therefore, the position or the local camera 53 corresponding to the test paper area 20 where the position is located is also determined and can be pre-acquired. Therefore, in some embodiments, step 300 of determining the first color block information from the first image includes: obtaining the first local camera 53 corresponding to the first color block 01, wherein the correspondence between the first local camera 53 and the first color block 01 is pre-established; obtaining an image captured by the first local camera 53 after the biological sample to be tested is added to the first dry chemical test strip 91 and a first reaction time T1 is elapsed as the first image; and determining the first color block information of the first color block 01 from the first image based on the position of the first color block 01 on the first dry chemical test strip 91. Similarly, step 300 of determining the second color block information from the second image includes: obtaining the second local camera 53 corresponding to the second color block 02, wherein the correspondence between the second local camera 53 and the second color block 02 is pre-established; obtaining an image captured by the second local camera 53 after the biological sample to be tested is added to the first dry chemical test strip 91 and a second reaction time T2 is elapsed as the second image; and determining the second color block information of the second color block 02 from the second image based on the position of the second color block 02 on the first dry chemical test strip 91.

[0295] In some embodiments, the imaging component 50 includes multiple local cameras 53, and the dry chemical test paper 90 placed on the supporting component 10 is relatively stationary with respect to the imaging component 50. Therefore, in some embodiments, the first dry chemical test paper 91 is also stationary and non-moving. That is, when the dry chemical test paper 90 is located in a test paper area 20, the dry chemical test paper 90 remains in this test paper area 20. Therefore, when the first dry chemical test paper 91 is in the test paper area 20 corresponding to the shooting field of view of any local camera 53, it can be photographed by the corresponding local camera 53 to obtain a first image and a second image. For example, the same local camera 53 can be used to capture the first image at one time and the second image at another time.

[0296] Therefore, in some embodiments, step 300 of determining the first color block information from the first image includes: obtaining the test paper area 20 where the first dry chemical test paper 91 is located; determining a target local camera 53 from the at least two local cameras 53 included in the imaging component 50 based on the test paper area 20 where the first dry chemical test paper 91 is located; obtaining an image captured by the target local camera 53 after the biological sample to be tested is added to the first dry chemical test paper 91 and a first reaction time T1 has elapsed as the first image; and determining first color block information of the first color block 01 from the first image based on the position of the first color block 01 on the first dry chemical test paper 91. Similarly, step 300 of determining the second color block information from the second image includes: obtaining an image captured by the target local camera 53 after the biological sample to be tested is added to the first dry chemical test paper 91 and a second reaction time T2 has elapsed as the second image; and determining second color block information of the second color block 02 from the second image based on the position of the second color block 02 on the first dry chemical test paper 91.

[0297] In some embodiments, each local camera 53 synchronously and periodically photographs the dry chemical test paper in the test paper area corresponding to its respective shooting field of view in a first preset cycle; wherein: the first reaction time T1 is the time corresponding to M first preset cycles after the biological sample to be tested is added to the first dry chemical test paper 91, and accordingly, the first image is the image of the first dry chemical test paper 91 obtained by photographing the first dry chemical test paper 91 after the biological sample to be tested is added and after M first preset cycles - it can be understood that here refers to the image obtained by one of the local cameras 53 (the local camera 53 corresponding to the test paper area 20 where the first dry chemical test paper 91 is located) after the biological sample to be tested is added and after M first preset cycles. The second reaction time T2 is the time length corresponding to N first preset cycles after the biological sample to be tested is added to the first dry chemical test paper 91. Accordingly, the second image is the image of the first dry chemical test paper 91 obtained by taking the first dry chemical test paper 91 after the biological sample to be tested is added and after N first preset cycles; M and N are preset positive integers and are not equal - it can be understood that here it refers to the image of the first dry chemical test paper 91 obtained by one of the local cameras 53 (the local camera 53 corresponding to the test paper area 20 where the first dry chemical test paper 91 is located) after the biological sample to be tested is added to the first dry chemical test paper 91 and after M first preset cycles.

[0298] The above is a brief description of the dry chemical testing method. In the example where the imaging component 50 includes a global camera 51, since the field of view of the global camera 51 can cover at least two test strip areas 20, the image captured by the global camera 51 at the same time can include multiple dry chemical test strips 90, thereby enabling the detection results of test items corresponding to one or more color blocks on different dry chemical test strips 90 to be obtained in the same image.

[0299] For example, in addition to the first dry chemical test paper 91, the dry chemical test paper 90 also includes a second dry chemical test paper 92, and the second dry chemical test paper 92 has at least a fourth color block 04 corresponding to the fourth test item, wherein the fourth test item corresponds to a preset fourth reaction time; the first image or the second image also has the second dry chemical test paper 92; the dry chemical detection method also includes a step: determining the fourth color block information based on the first image or the second image, and calculating the detection result of the fourth test item corresponding to the fourth color block 04 based on at least the fourth color block information. For example, the color blocks of the first dry chemical test paper 91 are added to the sample adding area 21 at time 0, and the color blocks of the second dry chemical test paper 92 are added to the sample adding area 21 at time 10s. The second reaction time T2 of the second color block 02 of the first dry chemical test paper 91 is 10s longer than the second reaction time T4 of the fourth color block 04 of the second dry chemical test paper 92. Thus, the second image contains the first dried test paper and the second dried test paper, and since the second image is taken after the second color block 02 of the first dry chemical test paper 91 is added to the biological sample to be tested and after the second reaction time T2, At this time, the fourth color block 04 of the second dry chemical test paper 92 is added with the biological sample to be tested and experiences the fourth reaction time T4. Therefore, in the second image, the second color block 02 of the first dried test paper and the fourth color block 04 of the second dried test paper have both reached their respective reaction times, so that the processor 70 can determine the second color block information of the second color block 02 and the fourth color block information of the fourth color block 04 based on the second image, and calculate the detection result of the second test item corresponding to the second color block 02 based on the second color block information, and calculate the detection result of the fourth test item corresponding to the fourth color block 04 based on the fourth color block information.

[0300] In a dynamic scenario, the first reaction time T1 and the second reaction time T2 can also be calibrated by the test paper area 20 to which the first dry chemical test paper 91 is delivered. Therefore, referring to FIG13 , the dry chemical test in some embodiments includes the following steps:

[0301] Step 120: The carrying component 10 is driven by the driving component 10a so that the dry chemical test paper placed on the carrying component 10 is transported in a preset direction among the multiple test paper areas 20; the dry chemical test paper 90 includes a first dry chemical test paper 91, and the first dry chemical test paper 91 has at least a first color block 01 corresponding to the first test item and a second color block 02 corresponding to the second test item; the multiple test paper areas 20 include a first reaction end area 29a preset for the first test item, and a second reaction end area 29b preset for the second test item and different from the first reaction end area 29a.

[0302] Step 130 : The same biological sample to be tested is added to the first color block 01 and the second color block 02 of the first dry chemical test paper 91 simultaneously through the sample adding component 30 .

[0303] Step 210: After the sample adding component 30 adds the same biological sample to be tested to the first color block 01 and the second color block 02 of the first dry chemical test paper 91, the first dry chemical test paper 91 is photographed by the imaging component 50 to obtain multiple images; wherein, the multiple images include at least a first image and a second image, the first image is an image of the first dry chemical test paper 91 photographed in the first reaction end area 29a, and the second image is an image of the first dry chemical test paper 91 photographed in the second reaction end area 29b.

[0304] In some embodiments, the imaging component 50 includes a global camera 51 , and the shooting field of the global camera 51 can cover the first reaction end area 29 a and the second reaction end area 29 b .

[0305] In some embodiments, the imaging component 50 includes at least a first local camera 53 and a second local camera 53 , wherein the shooting field of the first local camera 53 is the first reaction end area 29 a , and the shooting field of the second local camera 53 is the second reaction end area 29 b .

[0306] Step 300: Determine first color block information from the first image, and calculate the detection result of the first test item corresponding to the first color block 01 based on at least the first color block information, and determine second color block information from the second image, and calculate the detection result of the second test item corresponding to the second color block 02 based on at least the second color block information.

[0307] Referring to FIG. 14 , dry chemical testing in some embodiments includes the following steps:

[0308] Step 140: Add the biological sample to be tested to the color block 99 of the dry chemical test paper 90 located in the test paper area 20 through the sample adding component 30; the dry chemical test paper 90 includes a first dry chemical test paper 91, and the first dry chemical test paper 91 has at least a first color block 01 corresponding to the first test item and a second color block 02 corresponding to the second test item; the test paper area 20 includes the same reaction end area 29c preset for the first test item and the second test item; or, the first test item and the second test item are preset with the same reaction end time.

[0309] In some embodiments, step 140 of adding the biological sample to be tested to the color block 99 of the dry chemical test paper 90 located in the test paper area 20 through the sample adding component 30 includes: adding the biological sample to be tested to the first color block 01 on the first dry chemical test paper 91 through the sample adding component 30 at a first sample adding time, and adding the biological sample to be tested to the second color block 02 on the first dry chemical test paper 91 at a second sample adding time different from the first sample adding time.

[0310] In some embodiments, the test paper area 20 includes a first sample adding area 21a and a second sample adding area 21b different from the first sample adding area 21a. In step 140, the sample adding component 30 adds the biological sample to be tested to the first color block 01 on the first dry chemical test paper 91 in the first sample adding area 21a, and adds the biological sample to be tested to the second color block 02 on the first dry chemical test paper 91 in the second sample adding area 21b.

[0311] Step 220 : Using the imaging component 50 , an image of the first dry chemical test paper 91 is captured after the biological sample to be tested is added thereto.

[0312] Step 310: Calculate the test results of the first test item and the second test item based on the image captured by the first dry chemical test paper 91 in the same reaction end area 29 c or at the same reaction end time after the biological sample to be tested is added.

[0313] In some embodiments, multiple processing modes may also be provided. Referring to FIG. 15 , in some embodiments, dry chemical detection has a first processing mode and a second processing mode, and the dry chemical detection includes the following steps:
