Description

Rotary bar code making method, reading method and bar code reading device information reading method

The present disclosure relates to an information recognition method, and in particular to a rotary bar code making method, a rotary bar code reading method, and a bar code reading device information reading method.

Bar code is a quick identification mechanism for items such as commodities and experimental objects. Common barcodes such as one-dimensional barcodes or two-dimensional barcodes are set on the surface of these items for reading. When using one-dimensional barcodes or two-dimensional barcodes (such as PDF417) that scan one-dimensional barcodes, it is necessary to make barcodes. The reading device scans in a one-dimensional direction for reading.

However, if the bar code is placed on a rotating object, for example, by rotating the device that achieves the centrifugal effect, the one-dimensional reading device will read the outer and inner sides of the conventional rectangular bar code bar code line due to the rotation. The angular velocities are different, and the reading speeds of the inner and outer sides are inconsistent. Inconsistent read speeds prevent the reading device from correctly reading the bar code, which will result in erroneous readings or even no way to determine what information is being read.

Therefore, how to design a rotary bar code making method, a rotary bar code reading method, and a bar code reading device information reading method is an urgent problem to be solved in the industry.

Accordingly, one aspect of the present disclosure is to provide a rotary bar code making method comprising the steps of: providing a square bar code, wherein the square bar code has a lateral boundary extending in a reading direction and a vertical boundary perpendicular to the reading direction; The outer side of one of the two lateral boundaries defines a center of the circle; and the square bar code is expanded according to the center of the circle such that the two lateral boundaries become the two arcuate boundaries of the common center, so that the two longitudinal boundaries become the two side boundaries respectively connecting the two lateral boundaries, and each of the two The virtual extension lines of the side borders intersect at the center of the circle, forming a rotating bar code.

According to an embodiment of the present disclosure, the square bar code includes a bar code pattern between two horizontal boundaries and two longitudinal boundaries. After the square bar code is expanded according to the center of the circle, the bar code pattern becomes an arc bar code pattern.

In accordance with another embodiment of the present disclosure, the rotary bar code is read by the bar code reading device as it rotates relative to the central axis of rotation on a plane. The center axis of rotation is located on the center of the circle. The bar code reading device is at an appropriate distance from the plane to read the rotary bar code by the arc reading direction of the center of the circle with the two arcuate boundaries. The bar code reading device reads the rotary bar code starting from one of the two side boundaries.

According to still another embodiment of the present disclosure, the rotary barcode is a rotary one-dimensional barcode or a rotary two-dimensional barcode.

Another aspect of the present disclosure is to provide a rotary bar code reading method comprising the steps of: providing a rotary bar code having a two-curve boundary and a two-sided boundary, wherein the two arc-shaped boundaries are a common center with respect to the center of the circle, The side boundaries are respectively connected to the two curved boundaries, and the virtual extension lines of the two side boundaries intersect at the center of the circle, and the rotary bar code further includes an arc bar code pattern between the two curved boundaries and the two side boundaries; the rotary bar code is relatively flat on the plane Rotating perpendicular to the central axis of rotation of the plane, wherein the central axis of rotation is located on the center of the circle; and the bar code reading device that makes the appropriate distance from the plane reads the arc of the rotating bar code by the arc reading direction of the center of the circle with the two arcuate boundaries Bar code pattern.

In accordance with an embodiment of the present disclosure, the bar code reading device reads the rotary bar code from one of the two side boundaries.

According to another embodiment of the present disclosure, the rotary barcode is a rotary one-dimensional barcode or a rotary two-dimensional barcode.

According to still another embodiment of the present disclosure, the rotary bar code is fixed on the bearing surface of the rotating object, and when the rotating object rotates relative to the central axis of rotation, the rotary bar code is rotated.

Yet another aspect of the present disclosure is to provide a method for reading information of a rotating bar code reading device, comprising the steps of: providing a curved bar code having a two-curve boundary and two side boundaries, wherein the two arc-shaped boundaries are relative to the center of the circle The center of the circle is connected to the two curved boundaries, and the virtual extension lines of the two side boundaries intersect at the center of the circle. The curved bar code further includes an arc bar code pattern between the two curved boundaries and the two side boundaries, wherein the curved bar code is located On a plane; actuating a bar code reading device at an appropriate distance from the arcuate bar code to rotate relative to a central axis of rotation perpendicular to the plane, wherein the central axis of rotation is on the center of the circle; and the bar code reading device is bounded by a second arc The curved reading direction of the common center reads the curved bar code pattern of the rotating bar code; and decodes according to the read arc bar code pattern.

According to another embodiment of the present disclosure, the rotary barcode is a rotary one-dimensional barcode or a rotary two-dimensional barcode.

The advantage of applying the present disclosure is that the above object can be easily achieved by converting a square bar code into a rotary bar code, which can directly read the information of the object from the rotating bar code on the rotating object.

Please refer to Figure 1, Figure 2A and Figure 2B at the same time. FIG. 1 is a flow chart of a method for manufacturing a rotary bar code according to an embodiment of the disclosure. FIG. 2A is a schematic diagram of a square bar code 2 according to an embodiment of the disclosure. 2B is a schematic diagram of a rotary bar code 2' in an embodiment of the disclosure. The rotary bar code making method includes the following steps. (It should be understood that the steps mentioned in the present embodiment can be adjusted according to actual needs, and can be performed simultaneously or partially simultaneously, unless otherwise specified.

At step 101, a square bar code 2 as shown in Fig. 2A is provided. The square bar code 2 has two lateral boundaries 23a, 23b extending along the original reading direction 21 of the square bar 2, and longitudinal boundaries 25a, 25b perpendicular to the reading direction 21.

The square bar code 2 has a bar code pattern 22 between its lateral boundaries 23a, 23b and the longitudinal boundaries 25a, 25b. In various embodiments, the barcode pattern 22 can be a one-dimensional barcode, a two-dimensional barcode, or other type of barcode pattern. Barcode patterns can contain different information depending on their order and encoding. When the square bar code 2 is to be read, in an embodiment, the vertical boundary 25a can be started, so that the bar code reading device (not shown in FIG. 2A) is generated along the reading direction 21 and the square bar code 2. Dimensional motion, in order to scan to the longitudinal boundary 25b. However, if a rotational movement occurs between the square bar code 2 and the bar code reading device, the reading speeds of the inner and outer sides do not coincide due to the difference in the angular velocity between the outer side and the inner side. For example, if the lateral boundary 23a is farther from the central axis of rotation of the square bar code 2, and the lateral boundary 23b is closer to the central axis of rotation of the square bar code 2, the portion of the bar code pattern 22 near the lateral boundary 23a will have a higher The rotational speed, while the portion of the bar code pattern 22 near the lateral boundary 23b will have a lower rotational speed. The inconsistent reading speed makes the bar code reading device unable to read the bar code correctly, but will produce an erroneous reading result, or even completely unable to judge what the read information is.

Therefore, in step 102, a center 24 is defined on the outer side of one of the two lateral boundaries 23a and 23b. This center 24 can be determined by the center axis of rotation of the bar to be rotated. Next, in step 103, the square bar code 2 is developed based on the center 24 such that the two lateral boundaries 23a and 23b become the two arcuate boundaries 23a' and 23b' of the common center. Further, the two longitudinal boundaries 25a and 25b will be connected to the two side boundaries 25a' and 25b' of the two lateral boundaries 23a' and 23b', respectively. As shown in Fig. 2B, the virtual extension lines 27a and 27b of the two side borders 25a' and 25b' will intersect the center 24. Therefore, the bar code pattern 22 between the lateral boundaries 23a, 23b of the original square bar code 2 and the longitudinal boundaries 25a, 25b will become the arc bar code pattern 22' due to the expansion of the step 103. The square bar code 2 in Fig. 2A will thus be expanded into the rotary bar code 2' in Fig. 2B.

Please refer to Figures 3 and 4 at the same time. FIG. 3 is a flow chart of a method for reading a rotary bar code according to an embodiment of the disclosure. Figure 4 is a schematic illustration of a rotary bar code 2' located on a rotating object 4 in accordance with an embodiment of the present disclosure. The rotary bar code reading method includes the following steps. (It should be understood that the steps mentioned in the present embodiment can be adjusted according to actual needs, and can be performed simultaneously or partially simultaneously, unless otherwise specified.

In step 301, a rotating object 4 and a rotary bar code 2' are provided. The rotating object 4 can be an object of a different shape in different embodiments, however in Figure 4, the rotating object 4 is a disc shaped piece. In one embodiment, the rotating object 4 can be a fluid containing cassette for receiving a fluid therein. For example, the rotating object 4 can accommodate a substance that needs to be subjected to spin centrifugation such as blood, liquid medicine, fluid food, etc., to perform centrifugation by centrifugal force when the rotating object 4 is rotated.

The rotating object 4 has a bearing surface 40. The rotary bar code 2' is fixed to the carrying surface 40. In various embodiments, the rotary bar code 2' can be adhesively attached to the carrier surface in a different manner, such as adhesive, tape, or the like, or formed on the carrier surface 40 in other different manners. The method of manufacturing the rotary bar code 2' has been previously described, and therefore will not be described again.

The curved bar code pattern 22' of the rotary bar code 2' may contain identification information corresponding to the rotating object 4. For example, the identification information may include the rotating object information of the rotating object 4 itself, the number of the rotating object 4, or the content information of the object (such as the aforementioned fluid) contained in the rotating object 4, or the like, or a combination thereof. For example, if the rotating object 4 is a fluid containing cassette for accommodating a fluid, the rotating object information may be, for example, the size, weight or rotational speed of the rotating object 4 itself, or the like. The numbering can distinguish one of the different samples when performing centrifugation of a plurality of different samples with a plurality of rotating objects 4. The content information can be the type, weight or other related information of the fluid.

Next, in step 302, the rotating object 4 is rotated relative to the central axis of rotation 41 perpendicular to the bearing surface 40, and the rotating bar code 2' is rotated. In the present embodiment, the central axis of rotation 41 is located on the center 24 of FIGS. 2A and 2B, and is located at the center of the disk-shaped rotating object 4. In other embodiments, the position of the central axis of rotation 41 may be other designs depending on other situations, and is not limited to the embodiment.

In step 303, the bar code reading device 5 is disposed at an appropriate distance from the carrying surface 40 by the arc-shaped reading direction 51 of the center of the two arcuate boundaries 23a' and 23b' of the rotary bar code 2', from the two side boundaries 25a. One of 'and 25b' starts reading the curved bar code pattern 22' of the rotary bar code 2'. In the present embodiment, since the rotating object 4 is rotated in the clockwise direction, the arc reading direction 51 will be in the counterclockwise direction and will be read from the side boundary 25b' until the side boundary 25a'.

The bar code reading device 5 can be a device generally used to read the square bar code 2 as shown in FIG. 2A. However, due to the design of the rotary bar code 2', the curved bar code pattern 22' (large angular velocity) from the far side of the center 24 is wider than the curved bar code pattern 22' on the side closer to the center 24. The width of the angular velocity is small, so that the bar code reading device 5 can read the rotary bar code 2' in the arc reading direction with the two arc-shaped boundaries 23a' and 23b'. 'The reading speed of each position is the same, so the curved bar code pattern 22' of the rotary bar code 2' can be correctly read. Therefore, by the design of the rotary bar code 2', it is possible to easily read the rotary bar code 2' by the bar code reading device 5 when the rotary bar code 2' is rotated. In one embodiment, the bar code reading device 5 will be connected to a host (not shown) to transfer the results of the reading to the host for decoding. Based on the read curved bar code pattern 22', the bar code reading device 5 can perform decoding to obtain identification information corresponding to the rotating object 4.

Please also refer to Figure 5 and Figure 6. FIG. 5 is a flow chart of a method for reading information of a barcode reading device according to an embodiment of the disclosure. Figure 6 is a schematic illustration of a rotary bar code 2' located on a plane in accordance with an embodiment of the present disclosure. The bar code reading device information reading method includes the following steps. (It should be understood that the steps mentioned in the present embodiment can be adjusted according to actual needs, and can be performed simultaneously or partially simultaneously, unless otherwise specified.

In step 501, a rotary bar code 2' is provided. In the present embodiment, since the rotary bar code 2' itself does not rotate, it can also be called an arc bar code. The rotary bar code 2' can be attached to a plane, however this plane is the same as the rotary bar code 2' and does not rotate.

In step 502, the bar code reading device 5' at an appropriate distance from the rotary bar code 2' (ie, the arc bar code) is rotated to rotate relative to the central axis of rotation 41 perpendicular to the plane in which the rotary bar code 2' is located, wherein The central axis of rotation 41 is located on the center of the circle 24.

In step 503, the bar code reading device 5 is caused by the arc-shaped reading direction 51 of the center of the two arcuate boundaries 23a' and 23b' of the rotary bar code 2', from the two side boundaries 25a' and 25b' The curved bar code pattern 22' of the rotary bar code 2' is read. In the present embodiment, since the rotating object 4 is rotated in the clockwise direction, the arc reading direction 51 will be in the counterclockwise direction and will be read from the side boundary 25b' until the side boundary 25a'.

At step 504, decoding is performed based on the read curved bar code pattern 22'. In one embodiment, the bar code reading device 5 will be connected to a host (not shown) to transfer the results of the reading to the host for decoding. Therefore, by the design of the rotary bar code 2', the reading of the rotary bar code 2' can be easily performed when the bar code reading device 5 rotates.

An advantage of the application of the present disclosure is that by converting a square bar code into a rotary bar code, it is possible to enable a fixed reading device to directly read information of an object on a rotating object or to read on a rotating reading device. The information of the object can easily achieve the above purpose.

The present disclosure has been disclosed in the above embodiments, but it is not intended to limit the disclosure, and any person skilled in the art can make various changes and refinements without departing from the spirit and scope of the disclosure. The scope of protection of the disclosure is subject to the definition of the scope of the patent application.
