And step 120, determining a scanning gun to be connected according to the connection operation received in the operation area.
In a specific implementation, after the input method interface is displayed, whether a user performs an input operation in a keyboard region of the input method interface or not can be detected, and whether the user performs the operation in an operation region of the input method interface or not can also be detected, so that when the user performs the operation in the operation region of the input method interface, whether the operation performed in the operation region of the input method interface by the user is a connection operation or not can be determined; if the operation performed by the user in the operation area of the input method interface is a connection operation, the user operation may be determined as the connection operation received by the operation area, and then a device search may be performed based on the connection operation to search for a scan gun to be connected. Further, after the input method interface is displayed, the embodiment of the present invention may further include: monitoring an operation area of the input method interface; when user operation is monitored, judging whether the user operation is preset connection operation or not; and if the user operation is a preset connection operation, executing a step of determining a scanning gun to be connected according to the connection operation received in the operation area.

Further, on the basis of the above embodiment, after the connection is established between the scan gun and the scan gun target according to the preset bidirectional communication protocol, the scan gun connection method according to the embodiment of the present invention may further include: and sending an operation command received in the operation area to the scanning gun based on the connection, wherein the operation command is used for controlling the scanning gun.
Referring to fig. 3, a flowchart illustrating steps of a scan gun connection method according to an alternative embodiment of the present invention is shown. The scanning gun connection method can be applied to a mobile terminal, and specifically comprises the following steps:
And 320, monitoring an operation area of the input method interface.
Specifically, after the input method interface is displayed, the operation area of the input method interface may be monitored, so that the user operation submitted by the user on the operation area may be monitored, and whether the user operation is a preset connection operation may be determined. If the user operation is a preset connection operation, step 340 may be executed to determine a scan gun to be connected according to the connection operation received in the operation area. . If the user operation is not the preset connection operation, the user operation may be ignored, or a corresponding operation command may be generated based on operation information of the user operation, such as operation position information of the user operation, so as to jump to step 370 for execution according to the operation command.
And 340, when the user operation is a preset connection operation, performing device search based on the connection operation to obtain a candidate device.
And 350, selecting a scanning gun from the candidate devices so as to determine the selected scanning gun as the scanning gun to be connected.
Specifically, in the embodiment of the present invention, when the searched candidate device includes a scan gun, the scan gun may be screened from the searched candidate device, so as to generate a candidate device list based on the screened scan gun, and the candidate device list is displayed, so that the user may select the scan gun to be connected through the displayed candidate device list, that is, the user may select the scan gun to be connected through the selection operation submitted based on the selected device list. Optionally, in the embodiment of the present invention, selecting a scanning gun from the candidate devices may specifically include the following sub-steps:
substep 3501, presenting a list of candidate devices based on the scan guns contained in the candidate devices;
sub-step 3502, receiving a selection operation submitted based on the list of candidate devices;
and a substep 3503, taking the scanning gun corresponding to the selection operation as the selected scanning gun.
Specifically, after receiving a selection operation submitted by a user based on a candidate device list, the scan gun corresponding to the selection operation may be determined based on operation information of the selection operation, such as operation position information of the selection operation, and then the scan gun corresponding to the selection operation may be determined as the scan gun selected by the user, so as to use the selected scan gun as the scan gun to be connected.
Therefore, the embodiment of the invention displays the candidate equipment list based on the scanning guns contained in the candidate equipment, so that the user can select the scanning gun to be connected through the displayed candidate equipment list, and the user can conveniently select the scanning gun to be connected. In addition, the candidate device list in this embodiment may be generated based on the screened scan guns, and may not show information of other devices except the scan guns, and may specifically be used to show information of each scan gun to be selected, thereby improving user selection efficiency.
Of course, the scan gun to be connected may also be determined in other manners in the embodiment of the present invention, for example, when the searched candidate device only includes one scan gun, the scan gun included in the candidate device may be automatically determined as the scan gun to be connected, which is not limited in the embodiment of the present invention.
Further, after the candidate device is searched out, the scan gun connection method provided by the embodiment of the present invention may further include: determining a number of scan guns in the candidate device; if the number of the scanning guns in the candidate equipment is one, determining the scanning guns in the candidate equipment as the scanning guns to be connected; if the number of the scanning guns in the candidate equipment is more than one, executing a step of displaying a candidate equipment list based on the scanning guns contained in the candidate equipment, wherein the candidate equipment list is used for displaying all the scanning guns contained in the candidate equipment. Therefore, the number of the scanning guns contained in the candidate equipment is one, namely, under the condition that the searched candidate equipment contains one scanning gun, the scanning gun can be directly determined as the scanning gun to be connected, the selection of a user is not needed, the determination efficiency of the scanning gun to be connected is further improved, and the connection efficiency of the scanning gun can be further improved.
And step 360, establishing connection with the scanning gun according to a preset two-way communication protocol.
The bidirectional communication protocol comprises a Bluetooth serial port protocol or a Bluetooth low energy consumption protocol.
Optionally, the mobile terminal may establish a connection with the scanning gun through the bluetooth serial port according to a bluetooth serial protocol. Particularly, under the condition that the mobile terminal is provided with the bluetooth serial port, the mobile terminal can be connected with the scanning gun through the bluetooth serial port according to a bluetooth serial port protocol, so that bidirectional communication can be carried out with the scanning gun based on the connection in the following process, and data transmission and sending are realized. It should be noted that the bluetooth serial port may be an apparatus interface based on the SPP protocol, which can create a serial port between bluetooth apparatuses for data transmission, and the purpose of the bluetooth serial port may be to ensure a complete communication path between applications on two different apparatuses (i.e., two communicating apparatuses).
In another optional mode, the mobile terminal may establish a connection with the scanning gun according to a bluetooth low energy protocol, so that bidirectional communication may be subsequently performed with the scanning gun based on the connection, power consumption and cost are greatly reduced while data transmission and transmission are realized, and low-latency data transmission is realized.
And step 370, based on the connection, sending an operation command received in the operation area to the scanning gun, wherein the operation command is used for controlling the scanning gun.
Wherein the operating commands may include various commands for controlling the scan gun, such as at least one of: a data clear command, a shutdown command, a storage mode command, a normal mode command, a data upload command, an encoding format command, and the like, which is not particularly limited in this embodiment.
It should be noted that the data clear command in the embodiment of the present invention may be used to control the scan gun clear data, and the data clear command may be automatically generated based on a user operation submitted by a user in the input method operation area. For example, as shown in fig. 2, when a user clicks a "data clear" button in an operation area, an input method plugin installed in the mobile terminal may automatically generate a corresponding data clear command, so that the mobile terminal may receive the data clear command, and may send the data clear command to the scanning gun through the input method plugin, so that the scanning gun executes the data clear command to clear data in the scanning gun, thereby achieving a purpose of controlling the scanning gun to clear data.
The shutdown command in the embodiment of the invention can be used for controlling the shutdown of the scanning gun, and the shutdown command can be automatically generated based on the user operation submitted by the user in the input method operation area. For example, as shown in fig. 2, when a user clicks an "immediate shutdown" button in an operation area, an input method plug-in installed in the mobile terminal may automatically generate a corresponding shutdown command, so that the mobile terminal may receive the shutdown command for controlling the scanning gun to be immediately shutdown, and may send the shutdown command to the scanning gun through the input method plug-in, so that the scanning gun executes the shutdown command to be immediately shutdown, thereby achieving the purpose of controlling the scanning gun to be shutdown.
The storage mode command in the embodiment of the invention can be used for controlling the storage mode of the scanning gun, and the storage mode command can be automatically generated based on the user operation submitted by the user in the input method operation area. For example, as shown in fig. 2, when a user clicks a "storage mode" button in an operation area, an input method plug-in installed on the mobile terminal may automatically generate a corresponding storage mode command, so that the mobile terminal may receive the storage mode command of the scanning gun, and may send the storage mode command to the scanning gun through the input method plug-in, so that the scanning gun executes the storage mode command to switch the storage mode, and performs data storage according to the switched storage mode, thereby achieving the purpose of controlling the storage mode of the scanning gun.
The normal mode command in the embodiment of the invention can be used for controlling the scanning gun to enter the normal mode for data scanning, and the normal mode command can be automatically generated based on user operation submitted by a user in an input method operation area. For example, as shown in fig. 2, when a user clicks a "normal mode" button in an operation area, an input method plug-in installed on the mobile terminal may automatically generate a corresponding normal mode command, so that the mobile terminal may receive the normal mode command of the scanning gun, and may send the normal mode command to the scanning gun through the input method plug-in, so that the scanning gun executes the normal mode command to enter a normal mode for data scanning, thereby achieving the purpose of controlling the scanning gun to scan data.
The data uploading command in the embodiment of the invention can be used for controlling the scanning gun to start or suspend data uploading, and the data uploading command can be automatically generated based on user operation submitted by a user in the input method operation area. For example, as shown in fig. 2, when a user clicks a "data upload" button in an operation area, an input method plug-in installed on the mobile terminal may automatically generate a corresponding data upload command, so that the mobile terminal may receive the data upload command, and may send the data upload command to the scanning gun through the input method plug-in, so that the scanning gun executes the data upload command, thereby achieving the purpose of controlling the scanning gun to upload data. For example, when the scanning gun does not start data uploading yet, if the user clicks a "data uploading" button, a "data uploading" command can be sent to the scanning gun through the middle input method plug-in of the mobile terminal to control the scanning gun to start data uploading; in the process of uploading data by the scanning gun, if a user clicks a data uploading button, the scanning gun can be controlled to suspend data uploading after a data uploading command is sent to the scanning gun, and the purpose of controlling the data uploading of the scanning gun is achieved.
The encoding format command in the embodiment of the present invention may be used to control an encoding format of a scanning gun, where the encoding format may be a UTF-8 encoding format, or a chinese character internal code extended specification (GBK) encoding format, and the like, and the present embodiment does not specifically limit this. For example, as shown in fig. 2, when the user clicks the "GBK code" button in the operation area, the input method plug-in installed on the mobile terminal may automatically generate a corresponding code format command, so that the mobile terminal may receive the code format command and may send the code format command to the scanning gun through the input method plug-in, so that the scanning gun executes the code format command to set the code format to the GBK code format, thereby achieving the purpose of controlling the code format of the scanning gun. For another example, when the user clicks the "UTF-8 code" button in the operation area, the input method plug-in installed on the mobile terminal may automatically generate a corresponding code format command, so that the mobile terminal may receive the code format command, and may send the code format command to the scanning gun through the input method plug-in, so that the scanning gun executes the code format command to set the code format to the UTF-8 code format, thereby achieving the purpose of controlling the code format of the scanning gun.
To sum up, after the input method interface is displayed, the embodiment of the invention can receive the connection operation through the operation area of the input method interface, determine the scanning gun to be connected according to the connection operation, and establish connection with the scanning gun according to the preset two-way communication protocol, so that the scanning gun is identified as the non-keyboard device under the two-way communication protocol, thereby overcoming the defect that the input method soft keyboard is closed when the mobile terminal such as a mobile phone and the like is connected with the scanning gun in the prior art, solving the problem that the mobile terminal cannot pop up the soft keyboard during the process of using the scanning gun by a user so as to cause the user to be incapable of manually inputting the scanning gun by the user in the prior art, simultaneously transmitting and sending data, and realizing the two-way communication between the scanning gun and the mobile terminal.
