After acquiring the graphic code sent by the bar code reader, the host sends a control instruction, wherein the control instruction can be virtual resource information or an instruction for setting the bar code reader. The sound size of the bar code reader, the on-off state of the indicator light and the like can be set. After the barcode reader scans the commodity code or the payment code, the scanned barcode information is transmitted to a USB interface of the host through a KBW (Keyboard Wedge) mode, the host needs to identify a working mode of the barcode reader before receiving the barcode information sent by the barcode reader, and if the barcode reader is in a USB KBW mode, the host receives the barcode information from the barcode reader. If the bar code reader is in the USB HID mode, the host computer can send configuration information to the bar code reader. The bar code reader can only be in one mode at the same time, and when the bar code reader needs to switch the mode of the bar code reader, the corresponding graphic code needs to be scanned. For example, when a merchant scans a graphic code by using a barcode reader, the barcode reader is in a USBKBW mode, if the barcode reader needs to be set or receives HID data issued by a host, the barcode reader needs to scan the graphic code corresponding to the relevant setting to switch the barcode reader to a USB HID mode, and after the barcode reader is switched to the USB HID mode, the barcode reader can receive a control instruction from the host or receive other HID data sent by the host.
In view of the above problems, no effective solution has been proposed.

Detailed Description
In order to make the technical solutions better understood by those skilled in the art, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only partial embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
It should be noted that the terms "first," "second," and the like in the description and claims of this application and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application described herein are capable of operation in sequences other than those illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
For a better understanding of the above embodiments, the meanings of technical terms referred to in the embodiments of the present application are explained below:
KBW: either a software program or an embedded hardware device that translates digital signals from a bar code reader or disk reader into computer recognizable keyboard stroke codes. The software form of keyboardwelder intercepts digital signals as they arrive at the computer from the reader and translates them into keyboard-entered code words. The hardware version of the keypad wedge would insert a translation device between the reader and the keyboard. The data sent through the web will appear to be typed into the computer while the keyboard itself is still fully functional. Because the computer using the keyboard wedge cannot distinguish between data entering the computer from the scanning device and data entered into the computer from the keyboard, the wedge can incorporate a bar code identification function into an existing computer without modifying the software application.
HID: HID devices are devices that interact directly with humans, such as keyboards, mice, joysticks, etc. However, the HID device does not necessarily need to be human interface, as long as the devices complying with the HID class specification are HID devices. The exchanged data is stored in a structure called report (report) and the firmware of the device must support the format of the HID report. The host sends and requests the report in control and interrupt transmission to send and receive data. The format of the report is very flexible and can process any kind of data.
USB: for handling the interconnection of the electrical layer and the protocol layer. The USB bus interface is realized by a main controller, and the main controller is responsible for the transmission of data flow between the host and the USB equipment. These transmission data are treated as a continuous bit stream. Each USB device provides one or more interfaces that can communicate with the client, each interface consisting of 0 or more pipes that independently transfer data between the client and a particular terminal of the device. The USB driver establishes an interface and a pipeline for the real requirements of the host software, and when a configuration request is made, the main controller provides services according to the parameters provided by the host software. One USB interface can theoretically support 127 external devices. The USB device connected to the host may also include other USB interfaces in addition to the HID interface. For example, an image display device may use an HID interface for software control of brightness, contrast, and refresh rate, while using a conventional image interface for transmitting data to be displayed. The USB microphone may use real-time transmission to play voice while using the HID interface to control volume, oscillation, bass, etc.
In the related art, when the barcode reader communicates with the host through the USB interface on the host, the barcode reader is in a single mode, i.e., a USB KBW mode or a USB HID mode, and the barcode reader needs to scan a corresponding graphic code when the mode is switched. For example, when the barcode reader needs to be set, the barcode reader needs to scan the configuration code to switch to the USB HID mode, and when the host identifies that the barcode reader is in the USB HID mode, the host may issue the setting information to the barcode reader. The host computer can open and close the setting etc. to the strip code reader pronunciation size, the lamp of instruction. When the host computer issues the setting information to the bar code reader, the bar code reader is in a USB HID mode, cannot scan the commodity code or the payment code, and cannot send HBW data to the host computer. After the host computer finishes setting the bar code reader, the bar code reader needs to scan the switching code again to switch back to the USB KWB mode, and the commodity code can be continuously scanned and sent to the host computer, so that the host computer can carry out checkout work. Or after the barcode reader sends the KWB data to the host, if other HID data needs to be received from the host, the corresponding graphic code also needs to be scanned, so that the barcode reader is switched to the USB HID mode, which is tedious in operation, wastes much time, and has low working efficiency.
In order to solve the above problems, embodiments of the present application provide corresponding solutions, which are described in detail below.

Wherein, a plurality of data channels occupy the same physical channel. Wherein the data type transmitted by each data channel in the plurality of data channels is different. I.e. different data channels carry different types of data.
And step S304, when the data to be transmitted is detected, performing data interaction between the bar code reader and the host computer by adopting at least one of the plurality of data channels.
Based on the above steps, in the embodiment of the present application, the triggering condition for triggering data interaction by using one or more channels of the multiple data channels is to detect data to be transmitted, and the scan switching code is not used as the triggering condition for data interaction by using the multiple data channels in the related art, so that parallel transmission of KBW data and HID data can be realized.
In some embodiments of the present application, the data to be transmitted includes: a first type of data and a second type of data. The first type of data includes: control instructions sent by the host computer or virtual resource information corresponding to the bar code information, such as the amount of money; the second type of data includes: and the bar code reader scans the obtained bar code information.

After the consumer presents the payment code, the barcode reader scans the payment code presented by the consumer. At this time, the data to be transmitted is detected by the detection device to be KBW data, and the detection device may be a barcode reader, a host, or a third-party device.

However, the transaction amount in the host, and the associated transaction completion notification, is only visible to the merchant, and the host generates amount information in order to make the consumer aware of the transaction progress, and the payment amount. At the moment, the detection equipment detects that the data to be transmitted is HID data, and after the data to be transmitted is detected to be the HID data, the host sends the HID data, namely the money amount information to the bar code reader through the HID channel. After the bar code reader receives the amount information, the bar code reader can be controlled to display the amount information on a screen of the bar code reader, and/or the bar code reader is controlled to output the amount information in a voice broadcasting mode.

Therefore, the mode switching is not needed when the bar code reader needs to receive the HID data after sending KBW data. The technical effects of simplifying the operation of the bar code reader, saving the time of merchants and consumers and improving the service efficiency of the bar code reader are achieved, and the technical problems that in the related technology, when the bar code reader interacts with a host computer with different types of data, the related graphic codes need to be scanned, the operation is complex and the working efficiency of the bar code reader is low are further solved.
An embodiment of the present application further provides another communication method, fig. 4 is a schematic flowchart of a communication method according to an embodiment of the present application, and as shown in fig. 4, the method includes:
step S402, detecting a plurality of data types of data to be transmitted between the bar code reader and the host, wherein the plurality of data types at least comprise KBW data and HID data;
step S404, when multiple data types are detected, multiple data channels corresponding to the multiple data types are adopted to transmit corresponding data, wherein the multiple data channels occupy the same physical channel.
Step S404 may be implemented by various processing manners, for example, data of various data types are simultaneously transmitted in corresponding data channels. For another example, data of multiple data types are transmitted in corresponding data channels one after another. A plurality of data channels are distributed in the bar code reader, and the plurality of data channels at least comprise KBW channels and HID channels; the KBW channel is used to transmit KBW data and the HID channel is used to transmit HID data. Wherein, a plurality of data channels occupy the same physical channel. Wherein the data type transmitted by each data channel in the plurality of data channels is different.

The host and the bar code reader are internally provided with a driver corresponding to the data types transmitted by the plurality of data channels.
As an alternative embodiment of the present application, step S404 may be expressed as the following implementation: the bar code reader receives first type data issued by the host through an HID channel; the host receives the second type data sent by the bar code reader through the KBW channel.
When the data to be transmitted is detected to be the first type of data, the control host sends the first type of data to the bar code reader through the HID channel, and the bar code reader receives the first type of data sent by the host through the HID channel.
And when the data to be transmitted is detected to be the second type data, controlling the bar code reader to send the second type data to the host through the KBW channel, and receiving the second type data sent by the bar code reader through the KBW channel by the host.

For example: when KBW data and HID data are detected, rather than waiting KBW for the HID data to be transmitted after the data transmission is complete, both data can be transmitted as desired by the user. In an optional embodiment, when the host receives KBW data sent by the barcode reader through the KBW channel, if the merchant needs to set the barcode reader, the host can directly generate a control instruction of a relevant HID data type, and when the detection device detects that the host has the control instruction of the HID data type, the host can be directly controlled to issue the control instruction to the barcode reader through the HID channel.

However, the transaction amount in the host, and the associated transaction completion notification, is only visible to the merchant, and the host generates amount information in order to make the consumer aware of the transaction progress, and the payment amount. At the moment, the detection equipment detects that the data to be transmitted is HID data, and after the data to be transmitted is detected to be the HID data, the host sends the HID data, namely the money amount information to the bar code reader through the HID channel. After the bar code reader receives the amount information, the bar code reader can be controlled to display the amount information on a screen of the bar code reader, and/or the bar code reader is controlled to output the amount information in a voice broadcasting mode. The screen of the bar code reader displays the amount information and/or the bar code reader outputs the amount information in a voice broadcasting mode, and the amount information can also be controlled by the host.
In another alternative embodiment, the host computer is used to set up the barcode reader. If the bar code reader comprises a prompt tone in the working process, the prompt tone can be used for prompting a prompt 'tic' after the bar code reader scans a commodity code, and when the host computer sets the size of the prompt tone of the equipment of the bar code reader, the host computer can directly send a control instruction corresponding to the prompt tone setting to the bar code reader to set the prompt tone of the bar code reader no matter whether the host computer receives the graphic code data sent by the bar code reader, namely KBW data; for example: the prompt tone is turned off, the prompt volume is reduced, the prompt volume is increased, and the like. The bar code reader may also include an indicator light that is illuminated to indicate to the user that the payment was successful after the user successfully paid.
