3)用户使用两种支付方式体验不一致，不同的支付方式需寻找不同的受理装置；以及3) Users experience inconsistencies with the two payment methods, and different payment methods need to find different acceptance devices; and
4)由于支付方式的不一致，收银员需浪费大量的精力在培训用户正确支付上。4) Due to inconsistent payment methods, cashiers need to waste a lot of energy in training users to pay correctly.
第二类存在的缺点：Disadvantages of the second category:
1)用户体验不一致，用户使用NFC和二维码需分别对准pos机不同的感应装置；1) The user experience is inconsistent. Users using NFC and two-dimensional codes need to point at different sensing devices of the POS machine respectively.
2)收银员操作感较差。收银员使用pos终端结算两种支付方式时需要不同的操作方式，并且由于手持式pos终端具有一定的自重，操作较为麻烦。2) The cashier has a poor operation feeling. Cashiers need different operation methods when using the POS terminal to settle two payment methods, and because the handheld POS terminal has a certain weight, the operation is cumbersome.

具体实施方式detailed description
下面介绍的是本发明的多个实施例中的一些，旨在提供对本发明的基本了解。并不旨在确认本发明的关键或决定性的要素或限定所要保护的范围。The following describes some of the various embodiments of the present invention and is intended to provide a basic understanding of the present invention. It is not intended to identify key or critical elements of the invention or to limit the scope of protection.
第一实施方式First embodiment
首先，对于本发明的第一实施方式提出的非接受理和扫码读取二合一的扫码枪装置进行说明。First, a non-acceptable code scanning and code scanning device according to the first embodiment of the present invention will be described.
本发明的第一实施方式提出的非接受理和扫码读取二合一的扫码枪装置能够解决在同一位置同时受理非接交易和扫码交易时的相互干扰问题，能够实现统一和用户主控的交易受理方式。The non-receiving and code scanning two-in-one code scanning gun device provided by the first embodiment of the present invention can solve the problem of mutual interference when simultaneously receiving non-contact transactions and code scanning transactions at the same location, and can achieve unity and users Main transaction control method.
图1是表示本发明第一实施方式的扫码枪装置的外观示意图。FIG. 1 is a schematic external view showing a code scanning gun device according to a first embodiment of the present invention.
如图1所示，本发明第一实施方式的扫码枪装置具备：摄像头100，用于通过扫码读取条码信息；NFC天线200，用于接收非接信号；以及切换非接受理和扫描读取的切换开关300。As shown in FIG. 1, the code scanning gun device according to the first embodiment of the present invention includes: a camera 100 for reading barcode information by scanning a code; an NFC antenna 200 for receiving non-receiving signals; and switching non-receiving logic and scanning Read the switch 300.
其中，NFC天线200围绕设置在摄像头100区域的外围。切换开关300可以是设置扫码枪装置手握位置处的开关，也可以是采用扫码枪装置的扳手作为切换非接受理和扫描读取的切换开关300。The NFC antenna 200 is disposed around the periphery of the area of the camera 100. The changeover switch 300 may be a switch provided at a hand-held position of the code scanning gun device, or may be a switch 300 using a wrench of the code scanning gun device to switch non-acceptance and scanning reading.
图2是表示本发明第一实施方式的扫码枪装置的结构框图。如图2所示，本发明第一实施方式的扫码枪装置进一步具备：FIG. 2 is a block diagram showing a configuration of a code scanning gun device according to a first embodiment of the present invention. As shown in FIG. 2, the code scanning gun device according to the first embodiment of the present invention further includes:
摄像头模块400，用于获取并解析所述摄像头100读取的所述条码信息，例如，摄像头模块40识别二维码特征，解析二维码信息内容，包括寻找定位角点、判断角点位置、识别二维码范围、解析信息内容等；The camera module 400 is configured to acquire and analyze the barcode information read by the camera 100. For example, the camera module 40 recognizes the characteristics of the two-dimensional code and analyzes the content of the two-dimensional code information, including finding corner points, determining corner positions, Identify the QR code range, parse the information content, etc .;
非接处理模块500，用于产生射频场，并获取从NFC天线200接收到的非接信号，例如，非接处理模块500实现非接触卡读取、加密算法、防拆机等功能，使扫码 枪具备支持闪付交易等能力；The non-contact processing module 500 is configured to generate a radio frequency field and obtain a non-contact signal received from the NFC antenna 200. For example, the non-contact processing module 500 implements functions such as contactless card reading, encryption algorithms, tamper resistance, etc. The code gun has the ability to support flash payment transactions;
安全处理器600，用于对非接处理模块500获取的非接信号进行处理，并向非接处理模块500传递来自下述的主控处理器700的控制信号；以及The security processor 600 is configured to process the non-contact signal acquired by the non-contact processing module 500 and transmit a control signal from the main control processor 700 described below to the non-contact processing module 500; and
主控处理器700，用于对于各个模块进行控制，其中，为了切换非接受理和扫码读取，主控处理器700产生控制信号以通过摄像头模块400对摄像头的100打开和关闭进行控制并且通过非接处理模块500对NFC射频场的打开和关闭进行控制。The main control processor 700 is used to control various modules. In order to switch the non-receiving logic and scan code reading, the main control processor 700 generates a control signal to control the opening and closing of the camera 100 through the camera module 400 and The non-contact processing module 500 controls the opening and closing of the NFC radio frequency field.
另外，本发明第一实施方式的扫码枪装置还具备通信模块800以及电源模块900。通信模块800用于实现扫码枪装置与后台系统(如MIS系统)之间的通讯，完成指令交互、交易上送等，通讯的方式包括但不限于蓝牙通讯、USB通讯等。电源模块900为扫码枪装置提供电源。在本发明中对于通信模块800以及电源模块900没有进行特殊改进，因此再后续实施方式的说明中省略对通信模块和电源模块的描写和说明。The code scanning gun device according to the first embodiment of the present invention further includes a communication module 800 and a power module 900. The communication module 800 is used to implement communication between the code scanning gun device and a background system (such as the MIS system), to complete instruction interaction, transaction upload, and the like. The communication methods include, but are not limited to, Bluetooth communication and USB communication. The power module 900 provides power for the code scanning device. In the present invention, there are no special improvements made to the communication module 800 and the power module 900. Therefore, the description and description of the communication module and the power module are omitted in the description of the subsequent embodiments.
其中，主控处理器700根据来自切换开关的切换信号产生控制信号以使得打开摄像头100并且关闭射频场，或者使得关闭摄像头100并且打开射频场。Wherein, the main control processor 700 generates a control signal according to a switching signal from a switch, so that the camera 100 is turned on and the radio frequency field is turned off, or the camera 100 is turned off and the radio frequency field is turned on.
例如，在支付环节，作为一个示例，例如扫码枪装置可以默认设置为打开NFC射频场用来感应用户的NFC设备,同时默认摄像头打开并开启扫描二维码功能。如果用户要使用非接闪付交易时(即非接受理的情况下)，则可直接受理，执行相应的非接NFC交易流程。当用户要使用二维码支付时，收银员扣下切换开关300，则立即使得关闭射频场，摄像头100扫描用户的二维码，执行相应的二维码交易流程。由此能够避免用户使用同时具有二维码和非接功能的设备的相互干扰问题。For example, in the payment link, as an example, for example, the code scanning device may be set to turn on the NFC radio frequency field to sense the NFC device of the user by default, and at the same time, the default camera is turned on and the QR code scanning function is turned on. If the user wants to use a non-contact flash payment transaction (that is, in the case of non-acceptance), he can directly accept and execute the corresponding non-contact NFC transaction process. When the user wants to pay with a two-dimensional code, the cashier depresses the switch 300, which immediately causes the radio frequency field to be turned off. The camera 100 scans the user's two-dimensional code and executes the corresponding two-dimensional code transaction process. In this way, the problem of mutual interference between users using a device having a two-dimensional code and a non-contact function can be avoided.
以下，对于利用本发明第一实施方式的扫码枪装置实现的一个示例的具体环节进行说明。Hereinafter, a specific link of an example implemented by the code scanning gun device according to the first embodiment of the present invention will be described.
在进入支付环节前，NFC射频场处于关闭状态，非接受理功能不可用，摄像头模块400则视需要关闭或开启二维码读取功能(如，在使用装置进行商品扫码时，开启二维码读取，否则处于关闭状态)。Before entering the payment link, the NFC radio frequency field is turned off, and the non-receiving function is not available. The camera module 400 turns off or turns on the QR code reading function as needed (for example, when using the device to scan the product, the QR code is turned on. Code read, otherwise it is off).
在进入支付环节后，执行以下流程：After entering the payment process, the following process is performed:
(1)摄像头模块400，打开摄像头100，开始尝试读取二维码，并通知非接读取 模块500开启射频场来感应NFC设备(具备NFC功能的手机、银行卡片等)；(2)收银员询问顾客使用何种支付方式；(1) Camera module 400, turn on the camera 100, start to try to read the QR code, and notify the contactless reading module 500 to turn on the radio frequency field to sense NFC devices (NFC-enabled mobile phones, bank cards, etc.); (2) cashier Asks the customer what payment method to use;
·如果顾客使用二维码，则：If the customer uses a QR code:
收银员扣动切换开关300，主控处理器700收到来自切换开关300的切换信号后进行控制使得关闭射频场，具体地，主控处理器700通过安全处理器600关闭非接处理模块500的射频场(即可以通过关闭射频场的电源来实现)，扫码枪装置通过摄像头100由摄像头模块400读取二维码，执行二维码交易流程。The cashier pulls the switch 300, and the main control processor 700 controls the RF field to close after receiving the switching signal from the switch 300. Specifically, the main control processor 700 turns off the non-contact processing module 500 through the security processor 600. The radio frequency field (that is, it can be realized by turning off the power of the radio frequency field), the code scanning gun device reads the two-dimensional code by the camera module 400 through the camera 100, and executes the two-dimensional code transaction process.
·如果顾客使用非接闪付，则：收银员不扣动切换开关300，扫码枪装置读取卡片信息，执行非接闪付的交易流程。If the customer uses non-flash payment, the cashier does not pull the switch 300, the code scanning device reads the card information, and executes the non-flash payment transaction process.
(3)交易流程结束后，优选地，关闭NFC射频场和摄像头100，等待后续操作。(3) After the transaction process is completed, preferably, the NFC radio frequency field and the camera 100 are turned off, waiting for subsequent operations.

接着，首先，对于本发明的第二实施方式提出的非接受理和扫码读取二合一的扫码枪装置进行说明。Next, first, a non-acceptable code scanning and scanning code reader device according to a second embodiment of the present invention will be described.
本发明的第二实施方式提出的非接受理和扫码读取二合一的扫码枪装置与第一实施方式的扫码枪装置的不同之处在于，第二实施方式中不设置切换开关300，取而代之设置了距离传感器。The non-receiving and scanning code scanning device proposed by the second embodiment of the present invention is different from the code scanning gun device of the first embodiment in that the switch is not provided in the second embodiment. 300, replaced by a distance sensor.

图7是电流测算模块的测算原理图。FIG. 7 is a measurement principle diagram of the current measurement module.
如图7所示，当扫码枪装置的充电线圈320内有电流经过时，周围就会建立磁场，产生磁通。在扫码枪装置的充电线圈320中的电流发生变化时，靠近扫码枪装置的用户终端的线圈A中也产生了电流。由于存在耦合能量，导致场强发生变化，用户终端的线圈A上的电流发生变化，以扫码枪装置的充电线圈320的原有工作电流大小为基准，电流测算模块321测算电流变化大小。电流发生变化的大小与距离z有关，因此电流测算模块321通过测算变化电流的大小来判断距离z。As shown in FIG. 7, when a current passes through the charging coil 320 of the code scanning gun device, a magnetic field is created around the magnetic coil and a magnetic flux is generated. When the current in the charging coil 320 of the code scanning device is changed, a current is also generated in the coil A near the user terminal of the code scanning device.

When the current change in the charging coil 320 reaches a certain threshold means that the user equipment is close to the device to a certain distance, if the camera module 420 fails to read the two-dimensional code, the main control processor 720 sends a control signal to immediately open the RF field , Close the camera 120 and execute the NFC transaction acceptance process.
