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.
下面将结合具体实施方式,对图1所示的处理流程进行详细的说明,图1所示的处理流程可以由具有固件代码的穿戴设备执行。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.
步骤101,接收条码生成指令,获取条码生成指令对应的条码明文。穿戴设备的系统程序中可以集成有专用于生成条形码的固件代码,即可以理解为穿戴设备采用嵌入式平台,通过嵌入式系统来进行相关的处理。此处,嵌入式系统是一种“完全嵌入受控器件内部,为特定应用而设计的专用计算机系统”,与个人计算机这样的通用计算机系统不同,嵌入式系
统通常执行的是带有特定要求的预先定义的任务,如生成条形码的任务。由于嵌入式系统只针对一项特殊的任务,设计人员能够对它进行优化,减小尺寸降低成本。通常,嵌入式系统可以理解为一个存储在ROM中的嵌入式处理器控制板的控制程序。嵌入式系统的核心是由一个或多个预先编程好以用来执行少数几项任务的微处理器或者单片机组成。与通用计算机能够运行用户选择的软件不同,嵌入式系统上的软件通常是暂时不变的;所以可以称之为“固件”。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."
条码明文可以是用于生成条形码图像,未经加密(通常也未经编码转换)的字符串,这里所说的字符可以包括字母、数字和符号中的至少一种。由于条码明文还没有经过编码转换,因此,本文中也称作原始条码明文。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.
当用户需要在穿戴设备上生成并显示条形码时,可以点击穿戴设备上的条码生成按键,条码生成按键可以是物理按键也可以是虚拟按键。从而可以触发穿戴设备接收到条码生成指令,同时获取条码生成指令对应的原始条码明文。基于不同的情况,如下以原始条码明文为支付账户对应的明文,方案场景为手机支付为例,给出了几种获取原始条码明文的方式: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:
方式一,穿戴设备接收终端发送的条码生成请求,条码生成请求中携带有原始条码明文(和/或对应的条形码生成指令)。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).
在实施中,用户在购买一件商品后,可以选择使用支付账户来进行付款,这时,用户可以打开安装在终端上的支付类软件,点击明文生成按键,这时终端可以生成与该支付类软件的用户账户对应的原始条码明文,之后,终端可以通过NFC、蓝牙等近距离通信软件与穿戴设备建立连接,终端从而可以将原始条码明文发送给穿戴设备,穿戴设备则可以获取原始条码明文。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.
方式二,穿戴设备根据预先存储的明文生成算法自动生成原始条码明文。In the second manner, the wearable device automatically generates the original barcode plaintext according to the pre-stored plaintext generation algorithm.
在实施中,穿戴设备中可以安装有用于支付的支付类软件,用户在购买一件商品后,可以打开安装在穿戴设备上的支付类软件,点击明文
生成按键,穿戴设备则可以根据预先存储的明文生成算法生成与该支付类软件的用户账户对应的原始条码明文。或者,穿戴设备中无需安装上述支付类软件,只需要嵌入该支付类软件的明文生成算法,进而在用户点击明文生成按键后,穿戴设备可以根据明文生成算法获取到用户账户对应的原始条码明文。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.
此处,鉴于安全性考虑,上述用于支付类的原始条码明文可以是周期性变化的,即每条原始条码明文具备一定的有效期,在有效期过后,需要重新生成新的原始条码明文。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.
步骤102,对条码明文进行编码转换,得到条码值。穿戴设备的固件代码中(或者在穿戴设备的存储器中)可以预先存储有用于条形码转换的编码规则,穿戴设备可以根据编码规则对得到的原始条码明文进行编码转换,从而可以得到用于绘制条形码图像的条码值。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.
可选的,由于原始条码明文的种类多种多样,在步骤102之前可以确定获取到的原始条码明文的条码类型,相应的处理可以如下:穿戴设备确定原始条码明文对应的条码类型(下文也称作第一条码类型)。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).
穿戴设备可以在获取到原始条码明文后,根据原始条码明文的明文格式(如字符长度、字符种类、标识字符)的等信息确定原始条码明文对应的第一条码类型。或者,在生成原始条码明文的时候可以同时记录该原始条码明文的类型信息,穿戴设备可以直接根据该类型信息确定原始条码明文对应的第一条码类型。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.
可选的,基于上述确定了原始条码明文的条码类型的情况,步骤102的处理可以如下:穿戴设备根据预先存储在固件代码中(或穿戴设备的存储器中)的条码类型与编码规则的对应关系,确定第一条码类型对应的编码规则;根据第一条码类型对应的编码规则,对原始条码明文进行编码转换,得到条码值。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.
在实施中,穿戴设备中可以预先在固件代码中存储有多种条码类型和编码规则的对应关系,该对应关系中记录了每个条码类型下不同明文字符对应的条码值,表1示例性的给出了Code128与条码值的对应关系表。穿戴设备在确定了原始条码明文对应的第一条码类型后,可以在上
述对应关系中确定第一条码类型对应的编码规则。之后,可以继续根据第一条码类型对应的编码规则,对原始条码明文进行编码转换,从而得到对应的条码值。具体的,此处以Code128C编码为例来进行说明。目前微信/QQ钱包/支付宝均采用Code128C编码,Code128C编码包括起始字段、数据字段、校验字段和结束字段,其中,Code128C的起始字段统一为表1中ID105对应的“Start C”,数据字段则是用于指示用户账户的原始条码明文,Code128C的原始条码明文一般是长度为偶数的数字串编码,每两个数字为一位数据,校验字段由起始字段和数据字段计算可得,相应的计算公式为:校验字段=(起始字段对应的ID值+数据字段每位数据的顺序编号×数据字段每位数据值)%103,其中,“%103”为对103进行取余计算,结束字段为统一为表1中ID106对应的“Stop”。具体的,此处以原始条码明文为95270078为例,起始字段对应的ID为105,第1位数据为95,第2位数据为27,第3位数据为0,第4位数据为78,所以校验字段=(105+1*95+2*27+3*0+4*78)%103=51,对照表1,对95270078进行编码转换:起始字段Start C(bbsbssbbbss)+数据位[95(bsbbbbsbsss)+27(bbbsbbssbss)+00(bbsbbssbbss)+78(bbssssbsbss)+检验位51(bbsbbbsbsss)+结束位Stop(bbsssbbbsbsbb),从而可以得到条码值(bbsbssbbbssbsbbbbsbsssbbbsbbssbssbbsbbssbbssbbssssbsbssbbsbbbsbsssbbsssbbbsbsbb)。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).

步骤103,根据条码值绘制条形码图像,并显示条形码图像。 Step 103, drawing a barcode image according to the barcode value, and displaying the barcode image.
在实施中,穿戴设备在得到原始条码明文对应的条码值后,可以通过固件代码,将条码值绘制成条形码图像,进一步的,由于条码值只包含两种字符,可以分别选用两种不同颜色的线条(即条码线)来对应两种字符,即可以按字符顺序将两种颜色的线条紧密排布,即可生成相应的条形码图像,进而,穿戴设备可以将条形码图像显示在屏幕上。例如,对于上文95270078对应的条码值(bbsbssbbbssbsbbbbsbsssbbbsbbssbssbbsbbssbbssbbssssbsbssbbsbbbsbsssb
bsssbbbsbsbb),在本步骤中,只需将b用黑色线标出,s用白色线标出,就可以生成对应的条形码图像。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.
可选的,步骤103中绘制条形码图像的过程可以包括:确定每条条码线的起始点坐标和结束点坐标;根据穿戴设备的屏幕大小,以及条码值的位数,确定每条条码线的间距(即条码线的宽度);根据每条条码线的起始点坐标、结束点坐标和间距,将条码值中每个条码字符绘制成对应的条码线,生成条形码图像。在实施中,穿戴设备的生产人员可以在穿戴设备的固件代码中植入如下代码,从而穿戴设备可以完成相应的绘制条形码图像的处理。具体的,考虑到绘制条形码时是按照条码线逐一绘制,则可以先确定每条条码线的起始点坐标和结束点坐标,此处可以考虑用X-Y平面坐标来表示,则可以确定每条条码线的起始点的X坐标和Y坐标,以及结束点的X坐标和Y坐标。之后,生产人员可以根据穿戴设备的屏幕大小,以及条码值的位数来确定每条条码线的间距,每条条码线的间距即可以认为是每条条码线的宽度。最后,穿戴设备则可以根据上述确定的每条条码线的起始点坐标、结束点坐标和间距,将条码值中每个条码字符依次绘制成对应的条码线,从而,可以生成条形码图像。图2给出了一种简单的绘制过程示意图。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.
上述绘制条形码图像的代码可以如下:The above code for drawing a barcode image can be as follows:

在实施中,在穿戴设备根据原始条码明文绘制成条形码图像后,如果用户认为该条形码图像为常用条形码图像,则可以点击穿戴设备上的存储按键,这时,穿戴设备则可以接收到条形码图像存储指令,从而,穿戴设备可以将当前显示的条形码图像和其对应的原始条码明文进行对应存储。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.

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.
在实施中,在穿戴设备存储原始条码明文和条形码图像后,再次接收到对应某个原始条码明文的条码生成指令时,可以获取该原始条码明文,并可以判断本地是否存储有该原始条码明文对应的条形码图像。如果穿戴设备存储有原始条码明文对应的条形码图像,则可以直接显示存储的条形码图像,如果穿戴设备未存储有原始条码明文对应的条形码图像,则可以基于该原始条码明文进行步骤102和步骤103的处理。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.
