detailed description

In order to make the objects, technical solutions and advantages of the present application more clear, the embodiments of the present application will be further described in detail below with reference to the accompanying drawings.

The embodiment of the present application provides a method for generating a barcode, and the execution body of the method is a wearable device. Among them, a barcode (Barcode), which is referred to as a barcode, may include a 1D barcode and a 2D barcode. The wearable device may be a wearable device having a barcode generating function, such as a smart bracelet, a smart pen, a Bluetooth headset, or the like. The wearable device has a firmware code dedicated to generating a barcode, for example, a firmware code dedicated to generating a barcode can be integrated in its system program. The wearable device may include a short-range communication component for performing information interaction with other devices, and the short-range communication component may be an NFC (Near Field Communication) communication component or a Bluetooth communication component, and the wearable device may include a screen. Display the information that needs to be displayed during the process of generating the barcode, such as the original barcode plaintext, barcode image, and so on. The wearable device may include an input unit, such as a button, a touch screen, etc., and the user may perform an input operation that may be involved in generating a barcode on the wearable device through the input unit; the wearable device may include a processor, and the processor may be used to perform the wearable device. Various processing (such as processing performed in a process of controlling a smart device); the wearable device may further include a memory that can be used to record or store data generated by the wearable device in the process of generating the barcode and receive data from other devices. The wearable device can also include components such as sensors, output units, and power supplies. In this embodiment, the wearable device is taken as an example of a smart wristband, and a detailed description of the solution is performed. Other situations are similar, and the present embodiment is not described in detail.

The process flow shown in FIG. 1 will be described in detail below with reference to specific embodiments. The process flow shown in FIG. 1 can be performed by a wearable device having a firmware code.

Step 101: Receive a barcode generation instruction, and obtain a barcode plaintext corresponding to the barcode generation instruction. A firmware code dedicated to generating a barcode can be integrated into the system program of the wearable device, that is, it can be understood that the wearable device adopts an embedded platform and performs related processing through the embedded system. Here, the embedded system is a "special computer system that is completely embedded in the controlled device and designed for a specific application". Unlike a general-purpose computer system such as a personal computer, the embedded system is different. Commonly implemented are predefined tasks with specific requirements, such as the task of generating barcodes. Because the embedded system is only for a specific task, the designer can optimize it to reduce the size and cost. In general, an embedded system can be understood as a control program for an embedded processor control board stored in ROM. The core of an embedded system consists of one or more microprocessors or microcontrollers that are pre-programmed to perform a few tasks. Unlike a general-purpose computer capable of running a user-selected software, the software on an embedded system is usually temporarily unchanged; so it can be called "firmware."

The bar code plaintext may be a string of characters used to generate a barcode image, unencrypted (usually also unencoded), and the characters herein may include at least one of letters, numbers, and symbols. Since the bar code plaintext has not been encoded and converted, it is also referred to herein as the original bar code plaintext.

When the user needs to generate and display a barcode on the wearable device, the barcode generation button on the wearable device can be clicked, and the barcode generation button can be a physical button or a virtual button. Therefore, the wearable device can be triggered to receive the barcode generation instruction, and at the same time, obtain the original barcode plaintext corresponding to the barcode generation instruction. Based on the different situations, the original barcode is the plaintext corresponding to the payment account, and the solution scenario is the mobile payment as an example. Several ways to obtain the original barcode clear text are given:

In the first mode, the wearable device receives the barcode generation request sent by the terminal, and the barcode generation request carries the original barcode plaintext (and/or the corresponding barcode generation instruction).

In the implementation, after purchasing a product, the user may choose to use the payment account to make payment. In this case, the user can open the payment software installed on the terminal and click the clear text generation button, and the terminal can generate the payment class. The user's account of the software corresponds to the original bar code. After that, the terminal can establish a connection with the wearable device through NFC, Bluetooth, and other short-range communication software. The terminal can send the original bar code to the wearable device, and the wearable device can obtain the original bar code plaintext.

In the second manner, the wearable device automatically generates the original barcode plaintext according to the pre-stored plaintext generation algorithm.

In the implementation, the payment device may be installed in the wearable device, and after purchasing an item, the user may open the payment software installed on the wearable device, and click on the clear text. The button is generated, and the wearable device can generate the original barcode plaintext corresponding to the user account of the payment software according to the pre-stored plaintext generation algorithm. Alternatively, the wearable device does not need to install the payment software, and only needs to embed the plaintext generation algorithm of the payment software. After the user clicks the plaintext generation button, the wearable device can obtain the original barcode plaintext corresponding to the user account according to the plaintext generation algorithm.

Herein, in view of security considerations, the original bar code plaintext for the payment class may be periodically changed, that is, each original bar code plaintext has a certain validity period, and after the expiration date, a new original bar code plaintext needs to be regenerated.

Step 102: Perform coding conversion on the barcode plaintext to obtain a barcode value. In the firmware code of the wearable device (or in the memory of the wearable device), an encoding rule for barcode conversion may be pre-stored, and the wearable device may encode and convert the obtained original barcode plaintext according to the encoding rule, thereby obtaining a barcode image for drawing. Bar code value.

Optionally, the barcode type of the original barcode clear text is determined before the step 102, and the corresponding processing may be as follows: the wearable device determines the barcode type corresponding to the original barcode plaintext (hereinafter also referred to as Make the first barcode type).

After obtaining the original barcode clear text, the wearable device determines the first barcode type corresponding to the original barcode plaintext according to the plaintext format (such as the character length, the character type, and the identifier character) of the original barcode plaintext. Alternatively, the type information of the original bar code plaintext may be recorded at the same time when the original bar code plaintext is generated, and the wearable device may directly determine the first bar code type corresponding to the original bar code plaintext according to the type information.

Optionally, based on the foregoing determining the bar code type of the original bar code plaintext, the process of step 102 may be as follows: the correspondence between the bar code type and the encoding rule stored in the firmware code (or in the memory of the wearable device) pre-stored by the wearable device And determining an encoding rule corresponding to the first barcode type; encoding and converting the original barcode plaintext according to the encoding rule corresponding to the first barcode type, to obtain a barcode value.

In the implementation, the corresponding relationship between the barcode type and the encoding rule may be stored in the firmware code in advance, and the barcode value corresponding to different plaintext characters in each barcode type is recorded in the correspondence relationship. Table 1 is exemplary. A correspondence table between Code128 and bar code values is given. After the wearable device determines the first barcode type corresponding to the plain text of the original barcode, it can be on the The coding rule corresponding to the first barcode type is determined in the correspondence relationship. Then, the original bar code plaintext can be code-converted according to the coding rule corresponding to the first bar code type, thereby obtaining a corresponding bar code value. Specifically, the code 128C code is taken as an example here for description. At present, WeChat/QQ wallet/AlipPay adopt Code128C encoding. Code128C encoding includes start field, data field, check field and end field. The starting field of Code128C is unified as “Start C” corresponding to ID105 in Table 1. The field is used to indicate the original bar code plaintext of the user account. The original bar code plaintext of Code128C is generally a numeric string code of even length. Each two digits is a bit of data, and the check field is calculated by the start field and the data field. The corresponding calculation formula is: check field = (ID value corresponding to the start field + sequence number of each data of the data field × data value per bit of the data field) % 103, where "%103" is taken for 103 For the remainder calculation, the end field is unified to "Stop" corresponding to the ID 106 in Table 1. Specifically, the original bar code plain text is 95270078 as an example, the ID corresponding to the start field is 105, the first bit data is 95, the second bit data is 27, the third bit data is 0, and the fourth bit data is 78. So the check field = (105 + 1 * 95 + 2 * 27 + 3 * 0 + 4 * 78) % 103 = 51, compared to Table 1, encoding conversion of 95270078: start field Start C (bbsbssbbbss) + data bits [95 (bsbbbbsbsss) +27 (bbbsbbssbss) +00 (bbsbbssbbss) +78 (bbssssbsbss) + parity bit 51 (bbsbbbsbsss) + end bit Stop (bbsssbbbsbsbb), so that the bar code value can be obtained (bbsbssbbbssbsbbbbsbsssbbbsbbssbssbbsbbssbbssbbssssbsbssbbsbbbsbsssbbsssbbbsbsbb).

Step 103, drawing a barcode image according to the barcode value, and displaying the barcode image.

In the implementation, after obtaining the barcode value corresponding to the plain text of the original barcode, the wearable device may draw the barcode value into a barcode image by using the firmware code. Further, since the barcode value only includes two characters, two different colors may be selected respectively. The line (ie, the bar code line) corresponds to two characters, that is, the lines of the two colors can be arranged closely in character order to generate a corresponding barcode image, and the wearable device can display the barcode image on the screen. For example, for the bar code value corresponding to 95270078 above (bbsbssbbbssbsbbbbsbsssbbbsbbssbssbbsbbssbbssbbssssbsbssbbsbbbsbsssb Bsssbbbsbsbb), in this step, you only need to mark b with a black line and s with a white line to generate a corresponding barcode image.

Optionally, the process of drawing the barcode image in step 103 may include: determining a starting point coordinate and an ending point coordinate of each barcode line; determining a spacing of each barcode line according to a screen size of the wearing device and a number of bits of the barcode value. (ie, the width of the bar code line); according to the starting point coordinates, the end point coordinates and the spacing of each bar code line, each bar code character in the bar code value is drawn into a corresponding bar code line to generate a barcode image. In an implementation, the wearer of the wearable device can embed the following code in the firmware code of the wearable device so that the wearable device can complete the corresponding process of drawing the barcode image. Specifically, considering that the bar code is drawn one by one according to the bar code line, the start point coordinate and the end point coordinate of each bar code line may be determined first, and here, the XY plane coordinates may be considered, and each bar code line may be determined. The X and Y coordinates of the starting point, and the X and Y coordinates of the ending point. After that, the production personnel can determine the spacing of each bar code line according to the screen size of the wearable device and the number of bits of the bar code value, and the spacing of each bar code line can be regarded as the width of each bar code line. Finally, the wearable device can sequentially draw each bar code character of the bar code value into a corresponding bar code line according to the starting point coordinates, the end point coordinates and the spacing of each bar code line determined above, so that the barcode image can be generated. Figure 2 shows a schematic diagram of a simple drawing process.

The above code for drawing a barcode image can be as follows:

Optionally, for some commonly used barcodes that do not change, the wearable device can be selectively stored, and the corresponding processing can be as follows: when receiving the barcode image storage instruction, storing the original barcode plaintext and the barcode image in the wearable Inside the device.

In the implementation, after the wearable device draws the barcode image according to the original barcode, if the user thinks that the barcode image is a common barcode image, the storage button on the wearable device can be clicked, and the wearable device can receive the barcode image storage. The instructions, whereby the wearable device can store the currently displayed barcode image and its corresponding original barcode plaintext.

Optionally, based on the above-mentioned case of storing the original barcode plaintext and the barcode image, After obtaining the original barcode clear text, it is determined whether the corresponding barcode image is stored locally, and the corresponding processing may be as follows: when the wearable device receives the barcode generation instruction corresponding to the original barcode plaintext again, if the wearable device stores the original barcode plaintext The corresponding barcode image displays the barcode image.

In the implementation, after the wearable device stores the original bar code plaintext and the barcode image, and receives the bar code generation instruction corresponding to the plaintext of the original bar code again, the original bar code plaintext may be obtained, and it may be determined whether the original bar code plaintext is stored locally. Barcode image. If the wearable device stores the barcode image corresponding to the plain text of the original barcode, the stored barcode image may be directly displayed. If the wearable device does not store the barcode image corresponding to the original barcode plaintext, the steps 102 and 103 may be performed based on the original barcode plaintext. deal with.

In the embodiment of the present application, the system program of the wearable device is integrated with a firmware code for generating a barcode, and the wearable device receives the barcode generation instruction, and obtains the original barcode plaintext corresponding to the barcode generation instruction, and the wearable device according to the code pre-stored in the firmware code. The rule encodes and converts the original barcode plaintext to obtain a barcode value, and the wearable device draws the barcode value into a barcode image through the firmware code, and displays the barcode image. In this way, the firmware code dedicated to generating the barcode has a smaller amount of data and occupies less storage space, so that a device with a smaller storage space such as a wearable device can integrate the firmware code in the system program to implement the embedded platform.
