Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
In the actual processing, factors influencing the uploading speed of the Bluetooth base are many, for example, whether the Bluetooth base is in single-key value transmission or multi-key value transmission, the number of characters which can be uploaded in the same time is determined; for another example, the size of the transmission delay setting value determines the delay time that each key needs to be uploaded or released, and the output language determines whether to adopt an exchange (ALT) combined output mode to determine the uploading time, so that in the prior art, the scanning gun transmits data to the bluetooth base according to the default set reserved time, and the problem that the data is covered or lost easily occurs. It should be noted that the use of the ALT combined output method requires more upload time than the use of the ALT combined output method.
In order to solve the above problem, embodiments of the present invention provide a data transmission method and related device based on a bluetooth base, where base parameters of the bluetooth base are obtained, so that time required for uploading of a current bluetooth base can be determined according to the obtained base parameters when data is transmitted, a reserved waiting duration of data transmission can be determined according to the time required for uploading, data is transmitted according to the reserved waiting duration, and then data synchronization is solved, and the problem that the transmitted data is covered or lost is avoided.
Referring to fig. 1, a flowchart illustrating steps of a data transmission method based on a bluetooth cradle according to an embodiment of the present invention is shown. The embodiment is applicable to the data transmission situation based on the bluetooth base, for example, the data transmission situation based on the bluetooth base of the wireless scanning gun can be applicable, the data transmission method based on the bluetooth base can be executed by the data transmission device based on the bluetooth base, and specifically includes the following steps:
and step 110, acquiring the base parameters of the Bluetooth base.
The base parameters may include various parameters related to transmission of the bluetooth base, such as a base USB transmission mode parameter, a single-key/multi-key transmission parameter, an output mode parameter adopted by a keyboard language, and the like, which is not limited in this embodiment. It should be noted that the base USB transmission mode parameter may determine a base USB transmission mode; the single/multiple key transmission parameter may determine HID single key multiple key transmission; the output mode parameters for the keyboard language may determine whether the set keyboard language uses ALT combination output mode.
And step 120, determining the time required by uploading the Bluetooth base according to the base parameters.
The time required for uploading the bluetooth base may be time required for the bluetooth base to upload data currently, for example, time required for the bluetooth base to upload a piece of data to a computer currently.
Specifically, in this embodiment, when the scanning gun has data to upload, the base parameter related to transmission of the bluetooth base may be queried first, and then the time required for uploading of the current bluetooth base may be calculated according to the obtained base parameter, that is, the time required for currently uploading a piece of data by the bluetooth base may be calculated according to the base parameter, so that the reserved waiting time for data transmission may be determined according to the time required for uploading, and then step 130 is executed.
the reserved waiting duration may refer to a time reserved for waiting for completion of data uploading.
Specifically, in the data transmission process, the transmission time of each piece of data can be recorded, so that the transmission waiting time of the next piece of data can be determined according to the recorded transmission time, and then the next piece of data can be transmitted when the transmission waiting time of the next piece of data reaches the reserved waiting time, so that the situation that the next piece of data is transmitted to the Bluetooth base when the Bluetooth base does not finish uploading the data can be avoided, and the problem that the transmitted data is covered or lost is solved.
In actual processing, the base parameters of the bluetooth base can affect the data transmission time, and different base parameters have different effects on the data transmission time.
For example, when the base USB transmission mode is divided into the HID keyboard mode and the CDC virtual serial port mode, the base transmission time is relatively long when the acquired base USB transmission mode parameter is the HID keyboard mode parameter; and when the acquired base USB transmission mode parameter is the CDC virtual serial port mode, the base transmission time is relatively short. It should be noted that the HID keyboard mode is compatible with the system driver, the transmission speed is slow, and the next piece of data needs to be transmitted after the display is completed, so as to avoid the previous piece of data being covered; and the CDC virtual serial port mode: and a driving program is required to be installed, the transmission speed is high, and the transmission delay can be ignored.
For another example, when the base transmission parameters are single-key transmission parameters and multi-key transmission parameters, the transmission time is relatively long when the obtained base transmission parameters are single-key transmission parameters; and when the acquired base transmission parameters are multi-key transmission parameters, the transmission time is relatively short. It should be noted that the base transmission can adopt HID single-key multi-key transmission, and the HID single-key multi-key transmission can be divided into single-key transmission and multi-key transmission; the single-key transmission speed is low, the host USB can only transmit one character within each response time, and the system compatibility is strong; the transmission speed of multi-key transmission is fast, and the host USB can transmit at most 7 characters in each response time, but the system compatibility is poor, and the method is not suitable for an android (android) system.
When the output mode parameters adopted by the keyboard language are ALT combined output mode parameters, the transmission time is relatively long; and when the output mode parameters adopted by the keyboard language are non-ALT combined output mode parameters, the transmission time is relatively short. For example, when the keyboard language does not adopt the ALT combination output mode, 1 time of USB response time is required for transmitting one character, and the method is only suitable for existing characters on the keyboard; when the keyboard language adopts ALT combined output mode, USB response time is needed for transmitting one character for at least 3 times, but the method can be suitable for outputting characters of Chinese, Japanese, Korean and the like.
For another example, when the acquired base parameter is a base USB transmission delay setting parameter, different base USB transmission delay setting values may determine different transmission times, for example, a delay after one USB HID transmission may be set to adapt to different USB receiving devices that may need different transmission speeds.
Therefore, the embodiment of the invention can evaluate the time required for transmitting one piece of data by acquiring the base parameters of the Bluetooth base, and can set the corresponding timing time as the reserved waiting time, so that the transmission is correspondingly finished after the waiting timing is finished, and then the transmission of the next piece of data is carried out.
Furthermore, when the scanning gun has data to be uploaded, the embodiment of the invention can determine whether the data transmission mode is the bluetooth base transmission mode or not, and determine the time required by the bluetooth base to upload by acquiring the base parameters of the bluetooth base when the data transmission mode is the bluetooth transmission mode. Specifically, before obtaining the base parameters of the bluetooth base, the embodiment of the present invention may further include: acquiring target transmission data; judging whether a data transmission mode is a Bluetooth base transmission mode or not according to the target transmission data; if the data transmission mode is a Bluetooth base transmission mode, the step of acquiring the base parameters of the Bluetooth base can be executed, so that the time required by uploading the Bluetooth base is calculated according to the base parameters; if the data transmission mode is not the Bluetooth base transmission mode, other transmission modes can be adopted for data transmission. The target transmission data may refer to data that the scanning gun needs to upload, and may specifically include scanning data, stored data, and the like of the scanning gun, which is not specifically limited in this embodiment of the present invention.
It should be noted that the scan data may be data scanned by the scan gun in a scan mode, and the storage data may be data read by the scan gun from the storage space in a storage mode. Specifically, the scanning mode can be used as a common mode of the scanning gun, and in the common mode, the scanning gun can transmit scanned bar code data to the Bluetooth receiving base through Bluetooth transmission in real time and display the bar code data on a computer; under the storage mode, the scanning rifle can be with the bar code data storage of scanning at the inside memory space of scanning rifle to can be when needs are uploaded, if when scanning the upload data command bar code, the scanning rifle transmits the data of inside memory space in proper order for the bluetooth to receive the base and show on the computer according to the storage order.
Therefore, in an optional implementation of the present invention, the data transmission method based on the bluetooth base may be applied to a scanning gun, and the acquired target transmission data may specifically include scan data and/or storage data. The scanning data is data scanned by the scanning gun in a scanning mode, and the storage data is data read by the scanning gun from a storage space in a storage mode.
Further, in the case that the data transmission mode is a bluetooth base transmission mode, the data transmission method based on the bluetooth base according to the embodiment of the present invention may further determine whether the scanning gun establishes a data connection with the bluetooth base, so as to obtain base data of the bluetooth base when the scanning gun establishes the data connection with the bluetooth base, thereby calculating an upload required time of the bluetooth base according to the obtained base parameters, determining a reserved waiting duration according to the upload required time, and further performing data transmission according to the reserved waiting duration; and when the scanning gun does not establish data connection with the Bluetooth base, the data transmission is stopped and the prompt is given, so that the situation that the scanning gun always transmits data but does not have data display and abnormal alarm can be avoided.
Optionally, on the basis of the foregoing embodiment, the data transmission method based on a bluetooth base according to the embodiment of the present invention may further include, before acquiring the base parameters of the bluetooth base: acquiring target transmission data; judging whether a data transmission mode is a Bluetooth base transmission mode or not according to the target transmission data; if the data transmission mode is a Bluetooth base transmission mode, judging whether the scanning gun establishes data connection with the Bluetooth base or not; if the scanning gun is in data connection with the Bluetooth base, executing a step of acquiring base parameters of the Bluetooth base; and if the scanning gun does not establish data connection with the Bluetooth base, stopping data transmission and outputting abnormal connection prompt information.
In a specific implementation, the base parameters obtained in the embodiment of the present invention may include transmission parameters of the bluetooth base, and the transmission parameters may be used to determine a time required for the bluetooth base to currently upload data. Therefore, in an optional embodiment of the present invention, the determining the time required for uploading by the bluetooth cradle according to the cradle parameter may specifically include: extracting transmission parameters of the Bluetooth base from the base parameters; and determining the uploading time of the first transmission data based on the transmission parameters, and taking the uploading time as the uploading time of the Bluetooth base. The first transmission data may refer to a piece of data that needs to be transmitted currently, and for example, when the obtained target transmission data includes two or more pieces of data to be transmitted, the first transmission data is one piece of data to be transmitted in the target transmission data, and may be a first piece of data to be transmitted that needs to be transmitted in the target transmission data; the uploading time of the first transmission data may be the time required for uploading the piece of first transmission data, for example, the time required for the bluetooth cradle to upload the currently transmitted piece of data to the computer.
Of course, the base parameters obtained in the embodiment of the present invention may include other parameters of the bluetooth base, such as a base communication state parameter, besides the transmission parameters of the bluetooth base, which is not limited in this embodiment. It should be noted that the base communication state parameter may be used to determine whether the communication state of the bluetooth base is normal, for example, whether the USB connection state of the bluetooth base is normal may be determined to determine whether the USB transmission of the bluetooth base is normal, so that the abnormal USB connection state of the bluetooth base may be found in time.
Optionally, before determining the time required for uploading the bluetooth cradle according to the cradle parameter in the embodiment of the present invention, the method may further include: extracting base communication state parameters from the base parameters; judging whether the communication transmission state of the Bluetooth base is normal or not according to the base communication state parameter; if the communication transmission state of the Bluetooth base is normal, transmitting the first transmission data, and executing the step of determining the time required by uploading the Bluetooth base according to the base parameters; and if the communication transmission state of the Bluetooth base is abnormal, stopping data transmission and outputting a base transmission abnormality prompt message.
Referring to fig. 2, a flowchart illustrating steps of a data transmission method based on a bluetooth cradle according to an alternative embodiment of the present invention is shown. The data transmission method based on the bluetooth base provided by the embodiment can be applied to a scanning gun, and specifically comprises the following steps:
Specifically, when the scanning gun needs to upload data, target transmission data can be acquired, and the acquired target transmission data may include at least two pieces of data to be transmitted. The data to be transmitted may refer to data that needs to be uploaded currently.
In step 230, if the data transmission mode is the bluetooth base transmission mode, it is determined whether the scan gun establishes a data connection with the bluetooth base.
If the scanning gun and the Bluetooth base establish data connection, executing step 240 to obtain base parameters of the Bluetooth base; and if the scanning gun does not establish data connection with the Bluetooth base, stopping data transmission and outputting abnormal connection prompt information. Wherein, connect unusual suggestion information and can be used for the suggestion to scan the rifle and be connected unusually between the bluetooth base, if can indicate that the scanning rifle is not connected to bluetooth base etc. to can be in time terminal data transmission when scanning rifle and bluetooth base are connected unusually, avoid the problem of data loss.
And step 240, acquiring the base parameters of the Bluetooth base after judging that the scanning gun is in data connection with the Bluetooth base.
In the embodiment of the invention, after the scanning gun is in data connection with the Bluetooth base, the base parameters of the Bluetooth base connected with the scanning gun can be acquired by inquiring the base parameters of the Bluetooth base, so that the communication transmission state of the Bluetooth base and the time required for uploading data can be determined according to the base parameters.
Wherein, the communication state parameter can determine the communication transmission state of the Bluetooth base. The communication transmission state of the bluetooth base can be divided into a normal communication transmission state and an abnormal communication transmission state, which is not particularly limited in this embodiment.
And step 260, judging whether the communication transmission state of the Bluetooth base is normal or not according to the base communication state parameters.
Specifically, in this embodiment, after obtaining the base parameter, the communication state parameter may be extracted from the base parameter, so as to determine the communication transmission state of the bluetooth base according to the communication transmission state parameter, and further determine whether the communication transmission state of the bluetooth base is normal. If the communication transmission state of the bluetooth base is normal, step 270 is executed to transmit first transmission data, and the time required for uploading the bluetooth base is determined according to the base parameters; if the communication transmission state of the Bluetooth base is abnormal, the data transmission can be stopped, and the prompt message of the abnormal base transmission can be output. This unusual suggestion information of base transmission can be used for indicateing the bluetooth base and transmit unusual circumstances, if can indicate bluetooth base USB connection state unusual, with suggestion bluetooth base USB wire transmission unusual, thereby can avoid the condition that the scanning rifle does not know and give unusual suggestion when bluetooth base USB wire transmission is unusual, strengthened the communication interconnection of scanning rifle and bluetooth base, solved current scanning rifle and not stopped the data loss problem that data transmission leads to when bluetooth base USB wire transmission is unusual.
And 270, when the communication transmission state of the Bluetooth base is normal, transmitting the first transmission data, and determining the time required by uploading the Bluetooth base according to the base parameters.
The first transmission data is one piece of data to be transmitted in the target transmission data. Specifically, in the embodiment of the present invention, after it is determined that the communication transmission state of the bluetooth base is normal, a piece of data to be transmitted may be extracted from target transmission data to be used as first transmission data for data transmission, and a transmission parameter of the bluetooth base may be extracted from the base parameter to determine the upload time of the first transmission data based on the transmission parameter, and then the upload time may be used as the upload time of the bluetooth base.
Further, when the acquired target transmission data includes at least two pieces of data to be transmitted, the transmitting data according to the reserved waiting duration in the embodiment of the present invention may include: determining a transmission waiting time length; and when the transmission waiting time reaches the reserved waiting time, transmitting the next to-be-transmitted data in the target transmission data. The transmission waiting duration may refer to a time waiting for transmission of the next piece of data.
Specifically, after the first transmission data is transmitted, the present embodiment may determine the waiting time after the transmission of the first transmission data by obtaining the current time, determine the waiting time as the transmission waiting time, and compare the transmission waiting time with the reserved waiting time for data transmission to determine whether the transmission waiting time reaches the reserved waiting time, so that the transmission waiting time may continue to wait until the transmission waiting time does not reach the reserved waiting time, and transmit the next to-be-transmitted data when the transmission waiting time reaches the reserved waiting time until all to-be-transmitted data in the target transmission data is transmitted.
Further, the data transmission method based on the bluetooth base provided by the embodiment of the present invention may further include: judging whether the data to be transmitted in the target transmission data are completely transmitted or not; if the transmission of all the data to be transmitted in the target transmission data is not finished, after each piece of data to be transmitted is transmitted, executing the step of determining the transmission waiting time length so as to transmit the next piece of data to be transmitted in the target transmission data when the transmission waiting time length reaches the reserved waiting time length until all the data to be transmitted in the target transmission data are finished being transmitted; and if the data to be transmitted in the target transmission data are completely transmitted, outputting transmission completion prompt information. The transmission completion prompt message can prompt the completion of data transmission, if the transmission completion prompt message can be output according to the transmission completion prompt message to complete the transmission, the purpose of synchronously giving sound prompt after the transmission is completed is achieved, so that the situation that prompt sound is given when the scanning gun data transmission is completed and the Bluetooth base does not stop uploading data can be avoided, and the problem that the prompt sound is given when the Bluetooth base uploads data for a period of time can be avoided.
As an example of the present invention, as shown in fig. 3, when the scanning gun has data to upload, it may be determined whether the data transmission mode of the scanning gun is the bluetooth base transmission mode. If the data transmission mode of the scanning gun is the Bluetooth base transmission mode, whether the scanning gun base is in data connection with the Bluetooth base or not can be judged; otherwise, the scanning gun can be determined to perform data transmission through other transmission modes.
If the scanning gun base is in data connection with the Bluetooth base, the base parameters of the Bluetooth base can be acquired, so that the reserved waiting time length can be determined according to the base parameters of the Bluetooth base in the following process, and data can be transmitted according to the reserved waiting time length; if the scanning gun base does not establish data connection with the Bluetooth base, data transmission can be stopped and prompting can be carried out.
For example, when the scanning gun base and the bluetooth base establish data connection, the bluetooth base and the base parameters related to transmission may be firstly inquired to calculate the time required for uploading the currently transmitted data to the computer according to the acquired base parameters, so that a corresponding time may be set aside to wait for the data to be uploaded, and then the next data may be transmitted until the acousto-optic prompt is synchronously given when all data are transmitted. Specifically, as shown in fig. 3, after it is determined that the scan gun base and the bluetooth base establish data connection, the base parameter of the bluetooth base may be obtained, and then it may be determined whether the bluetooth base USB transmission is normal according to the base communication state parameter included in the base parameter, so that when the bluetooth base USB transmission is normal, the first transmission data may be transmitted and the time T required for transmitting the first transmission data on the base may be calculated according to the base parameter, that is, the uploading time of the first transmission data is determined, so that the uploading time is used as the uploading time of the bluetooth base; when the transmission of the USB of the Bluetooth base is abnormal, namely when the transmission of the USB of the Bluetooth base is abnormal, the data transmission is stopped and the prompt is given, so that the situation that the scanning gun does not know and does not stop the data transmission and does not give an abnormal prompt when the wired transmission of the USB of the Bluetooth base is abnormal is avoided, and the purpose of timely interrupting the data transmission when the USB of the Bluetooth base is abnormal is achieved.
It can be seen that when the bluetooth connection is normal and the USB of bluetooth base and computer is connected unusually, namely when the connection between scanning rifle and receiving base is normal and the connection between bluetooth base and the computer is unusual, this example obtains the base parameter through the scanning rifle, can in time discover that base USB is connected the state unusually, and stop data transmission to can give and avoid the scanning rifle to transmit always but receiving arrangement does not have data display, does not have the condition of unusual warning.
In addition, when the connection between the bluetooth base and the USB of the computer is normal, namely when the USB transmission of the bluetooth base is normal, the reserved waiting time of data transmission can be determined according to the time required for uploading of the bluetooth base, so that data can be transmitted according to the reserved waiting time, and a transmission completion prompt can be given after the data transmission is completely completed, so that the problem that the transmission completion prompt time is inaccurate due to inaccurate estimation of the uploading time of the bluetooth base in the prior art is solved.
Specifically, after the reserved waiting time of data transmission is determined, the next data to be transmitted can be transmitted when the transmission waiting time reaches the reserved waiting time, as shown in fig. 3, the next data is transmitted after waiting for T time, and then whether data transmission is completely completed is judged, so that the step that the scanning gun needs to upload data when the scanning gun needs to upload the data can be returned to after the data transmission is judged to be not completely completed until the data transmission is completely completed, so that a transmission completion prompt can be given when the data transmission is completely completed, and for example, a sound prompt is given synchronously when the data transmission is completed.
In summary, the embodiment of the invention enables the scanning gun to accurately calculate the time required by the bluetooth base to upload each piece of data to the computer by acquiring the base parameters of the bluetooth base, thereby reserving an accurate interval time to transmit the next piece of data, saving the transmission time, ensuring that the transmitted data is not covered or lost, improving the stability and safety of data transmission, strengthening the communication and interconnection between the scanning gun and the bluetooth base, improving the synchronism of data transmission, and further enabling the scanning gun to give a transmission completion prompt more accurately.
In addition, the scanning gun in the embodiment of the invention can determine the USB connection state of the Bluetooth base through the acquired base communication state parameters, so that the scanning gun can timely respond according to the USB connection state of the Bluetooth, and if the Bluetooth connection is normal but the USB connection between the Bluetooth base and a computer is abnormal, the scanning gun can timely find and stop data transmission, thereby avoiding the situation that the scanning gun always transmits but has no data display and no abnormal alarm, and achieving the purpose of timely interrupting data transmission when the Bluetooth base is abnormal.
