[0027] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0028] The method for determining the parameters sent by the code reader provided in the embodiment of the present application can be applied to the following examples: Figure 1 In the application environment shown. The code reader 102 communicates with the terminal 104 via a USB interface, a serial port, Bluetooth or a network. When the code reader 102 communicates with the terminal 104 via a USB interface, the connection diagram between the code reader 102 and the terminal 104 is as shown in FIG. Figure 2 As shown, the code reader 102 is connected to the terminal 104 via an HID cable, and the code reader 102 inputs a character string into the terminal 104 via an HID keyboard input protocol. The terminal 104 may be, but is not limited to, various personal computers, laptops, smart phones, tablet computers, IoT devices, and portable wearable devices. The IoT devices may be smart speakers, smart TVs, smart air conditioners, smart car-mounted devices, etc. The portable wearable devices may be smart watches, smart bracelets, head-mounted devices, etc.

[0029] In one embodiment, Figure 3 As shown, the embodiment of the present application provides a method for determining parameters sent by a code reader, and the method is applied to Figure 1The terminal 104 in the example is used for explanation. It is understandable that the computer device may include at least one of a terminal and a server. The method includes the following steps:

[0030] Step 302: receiving a plurality of first transmission character strings transmitted by a code reader based on a preset time interval to obtain a first received character string; the number of characters in the plurality of first transmission character strings varies in a directional manner.

[0031] The code reader refers to a device for reading pattern information, and the code reader can be used to read the pattern information of a barcode or the pattern information of a QR code. The code reader can be an industrial code reader. The pattern information read by the code reader can be sent to the computer device in the form of a character string. The preset time interval refers to a preset time interval, and the preset time interval is the interval between sending two first transmission character strings. The preset time interval can be set to a longer time interval, for example, the preset time interval can be 200 milliseconds, or 220 milliseconds. The first transmission character string refers to a character string sent by the code reader to the computer device for determining the target transmission length, and the first transmission character string includes at least one character, and the characters in the first transmission character string can be at least one of numbers and letters, etc., and the characters in the first transmission character string can be the same or different. The number of characters in each of the multiple first transmission character strings is not equal, and the number of characters in the multiple first transmission character strings changes in a directional manner. It can be understood that the multiple first transmission character strings have a fixed arrangement order, and the number of characters in the first transmission character string gradually increases or decreases according to the fixed arrangement order. Directional changes refer to changes in a fixed direction, and directional changes include increasing and decreasing. Increasing refers to a gradual increase, and decreasing refers to a gradual decrease. For example, among the multiple first sent strings, the first first sent string is "1", the second first sent string is "22", the third first sent string is "333", the fourth first sent string is "4444", the fifth first sent string is "aaaaa", the sixth first sent string is "bbbbbb", the seventh first sent string is "ccccccc", etc.

[0032] The first received character string refers to a character string composed of characters received by the computer device, and the first received character string includes multiple complete first sent character strings and multiple incomplete first sent character strings. It can be understood that due to the limited receiving performance of the computer device, for the first sent character string with a smaller number of characters, the computer device can receive it within the preset time interval, while for the first sent character string with a larger number of characters, the computer device cannot receive it within the preset time interval.

[0033] Exemplarily, after entering the transmission parameter determination mode, the code reader sends a first transmission string to the computer device at a preset time interval according to the arrangement order in which the number of characters of the multiple first transmission strings changes in a directional manner, and the computer device obtains a first received string. The transmission parameter determination mode refers to the mode in which the code reader is used to determine the transmission parameters. In the transmission parameter determination mode, the code reader will send a string to the computer device according to a preset rule, simulating that the read pattern information is sent to the computer device in the form of a string. The last character in the first transmission string can be a division character, which is different from the other characters in the first transmission string and is only used as the last character of each first transmission string. For example, taking m as the division character, the first first transmission string in the multiple first transmission strings is "m", the second first transmission string is "2m", the third first transmission string is "33m", the fourth first transmission string is "444m", the fifth first transmission string is "aaaam", the sixth first transmission string is "bbbbbm", the seventh first transmission string is "ccccccm", etc.

[0034] In one embodiment, after entering the transmission parameter determination mode, the code reader sends a first transmission string and a dividing character to the computer device at a preset time interval according to the arrangement order in which the number of characters of the multiple first transmission strings changes in a directional manner, and the computer device obtains the first received string. The dividing character can be a line feed character, a pre-set character, etc.

[0035] In one embodiment, the computer device obtains the first received character string, including: the computer device displays the received characters in a text receiving box, and if no characters are received within a preset waiting time, the character sequence in the text receiving box is determined as the first received character string. The preset waiting time refers to the longest waiting time set in advance, for example, the preset waiting time is 5 seconds or 10 seconds.

[0036] Step 304: Determine a target sending length based on the plurality of first sending character strings and the first receiving character strings.

[0037] The target sending length refers to the maximum number of characters in a string sent each time when the barcode reader is in working mode. The target sending length is one of the parameters in the barcode reader sending parameters.

[0038] Exemplarily, the computer device divides the first received character string into a plurality of first sub-character strings according to a dividing character in the first received character string, and determines a target sending length based on the plurality of first sending character strings and the plurality of first sub-character strings.

[0039] In one embodiment, after determining the target sending length, the method further includes: recording the first received character string and the target sending length in a target record file. The target record file is used to perform traceability control on the determination of the sending parameters of the code reader.

[0040] In one embodiment, after determining the target sending length, the method further includes: setting the sending length of the code reader to the target sending length.

[0041] Step 306, receiving multiple second transmission character strings sent by the code reader based on multiple candidate time intervals to obtain a second received character string; the interval lengths of the multiple candidate time intervals vary in a directional manner; the number of characters in the second transmission character string is equal to the target transmission length.

[0042] Among them, the candidate time interval refers to a pre-set time interval. The interval lengths of multiple candidate time intervals are not equal, and the interval lengths of multiple candidate time intervals are directionally changed. It can be understood that the multiple candidate time intervals have a fixed arrangement order. According to the fixed arrangement order, the interval lengths of the candidate time intervals gradually increase or decrease. The difference between two adjacent candidate time intervals can be set according to actual needs, and there is no restriction here. For example, the multiple candidate time intervals are 200 milliseconds, 190 milliseconds, 180 milliseconds, 170 milliseconds, 160 milliseconds, 150 milliseconds, 140 milliseconds, and 130 milliseconds, etc., or the multiple candidate time intervals are 200 milliseconds, 180 milliseconds, 160 milliseconds, 140 milliseconds, 120 milliseconds, 100 milliseconds, 80 milliseconds, and 60 milliseconds, etc.

[0043] The second transmission string refers to a string sent by the code reader to the computer device for determining the target transmission time interval. The number of characters contained in the second transmission string is equal to the target transmission length. The characters in the second transmission string can be at least one of numbers and letters, and the characters in the second transmission string can be the same or different. For example, the target transmission length is 5 characters, and the first second transmission string of the plurality of second transmission strings is "00000", the second second transmission string is "11111", the third second transmission string is "22222", the fourth second transmission string is "44444", the fifth second transmission string is "aaaaa", the sixth second transmission string is "bbbbb", the seventh second transmission string is "ccccc", etc.

[0044] Exemplarily, after determining the target transmission length, the computer device sends the target transmission length to the code reader, and the code reader generates a plurality of second transmission strings of the target transmission length, and sends a second transmission string to the computer device every other candidate time interval according to the arrangement order of the interval lengths of the plurality of candidate time intervals in a directional change, and the computer device obtains a second received string. The last character in the second transmission string can be a division character, and the division character is different from the other characters in the second transmission string, and is only used as the last character of each second transmission string. For example, with n as the division character, the target transmission length is 5 characters, and the first second transmission string in the plurality of second transmission strings is "0000n", the second second transmission string is "1111n", the third second transmission string is "2222n", the fourth second transmission string is "4444n", the fifth second transmission string is "aaaan", the sixth second transmission string is "bbbbn", the seventh second transmission string is "ccccn", etc.

[0045] In one embodiment, after determining the target transmission length, the computer device sends the target transmission length to the code reader, and the code reader generates a plurality of second transmission character strings of the target transmission lengths, and sends a second transmission character string and a division character to the computer device every candidate time interval according to the arrangement order of the time lengths of the plurality of candidate time intervals in a directionally changing manner, and the computer device obtains a second received character string. The division character may be a line feed character or a pre-set character, etc.

[0046] In one embodiment, the computer device obtains the second received character string, including: the computer device displays the received characters in a text receiving box, and if no characters are received within a preset waiting time, determines the character sequence in the text receiving box as the second received character string.

[0047] In one embodiment, after determining the target sending length, the computer device generates multiple second sending strings of the target sending lengths, and sends the multiple second sending strings of the target sending lengths to the code reader. The code reader obtains the multiple second sending strings of the target sending lengths, and sends a second sending string to the computer device every candidate time interval in an arrangement order in which the interval lengths of the multiple candidate time intervals change in a directionally changing manner, and the computer device obtains a second received string.

[0048] Step 308: Determine a target sending time interval from a plurality of candidate time intervals based on the plurality of second sending character strings and the second receiving character strings.

[0049] The target sending time interval refers to the time interval between two character strings sent by the barcode reader in working mode. The target sending time interval is one of the parameters in the barcode reader sending parameters.

[0050] Exemplarily, the computer device divides the second received character string into a plurality of second sub-character strings according to the dividing characters in the second received character string, and determines the target sending time interval based on the plurality of second sending character strings and the plurality of second sub-character strings.

[0051] In one embodiment, after determining the target sending time interval, the method further includes: recording the second received character string and the determined target sending time interval in a target recording file.

[0052] In one embodiment, after determining the target sending time interval, the method further includes: setting the sending time interval of the code reader to the target sending time interval.

[0053] In the above-mentioned method for determining the sending parameters of the code reader, a plurality of first sending strings sent by the code reader based on a preset time interval are received to obtain a first receiving string. Through the plurality of first sending strings and the first receiving string, the longest string that can be received by the computer device within the preset time interval can be determined, thereby determining a target sending length that matches the receiving performance of the computer device; a plurality of second sending strings sent by the code reader based on a plurality of candidate time intervals are received to obtain a second receiving string. Through the plurality of second sending strings and the second receiving string, the shortest time interval required for the computer device to receive a string of the target sending length can be determined, thereby determining the target sending time interval, that is, the determination of the sending parameters of the code reader can be completed through the computer device and the code reader, and the automation of the determination of the sending parameters of the code reader is realized, thereby improving the efficiency of determining the sending parameters of the code reader.

[0054] In one embodiment, Figure 4 As shown, based on a plurality of first transmission character strings and a first reception character string, determining a target transmission length includes:

[0055] Step 402: divide the first received character string into a plurality of first sub-character strings based on the dividing characters in the first received character string.

[0056] The dividing character refers to a character used to divide the first received string into a plurality of first substrings. The dividing character can be set according to actual needs, and the dividing character can be a line break character or other set characters. The dividing character can be located at the end of the first sent string, or can be not in the first sent string. The first substring refers to a string consisting of some continuous characters in the first received string.

[0057] Exemplarily, the computer device divides the first received character string into a plurality of first sub-character strings according to a plurality of dividing characters in the first received character string.

[0058] Step 404 : sequentially compare the first sent string with the plurality of first substrings in order of the number of characters of the plurality of first sent strings from short to long.

[0059] Exemplarily, the computer device obtains the current first sent string in order of the number of characters from short to long, compares the current first sent string with multiple first substrings, and when there is a first substring that is identical to the current first sent string, determines the next first sent string of the current first sent string as the updated current first sent string, and repeats the step of comparing the current first sent string with the multiple first substrings until there is no first substring that is identical to the current first sent string, and determines the current first sent string as the target first sent string.

[0060] Step 406: When there is no first substring identical to the target first sent string, determine a target sent length based on the target first sent string.

[0061] Exemplarily, when there is no first substring identical to the target first sent string, the computer device determines the target sent length based on the directional change trend of the number of characters of the target first sent string and the plurality of first sent strings.

[0062] In this embodiment, the first received string is divided into multiple first substrings by dividing characters in the first received string, some of the first substrings are complete first sent strings, and some of the first substrings are incomplete first sent strings. When there is no first substring identical to the target first sent string, it indicates that the target first sent string cannot be completely received by the computer device, and the number of characters in the target first sent string exceeds the maximum number of characters allowed by the receiving performance of the computer device. Therefore, the number of characters slightly smaller than the number of characters in the target first sent string can be determined as the target sending length, thereby realizing the automation of the determination of the target sending length, thereby improving the efficiency of determining the target sending length in the sending parameters of the code reader.

[0063] In one embodiment, determining a target sending length based on a target first sending character string includes:

[0064] When the number of characters in multiple first sent strings changes in a decreasing manner, the number of characters in the first sent string adjacent to the target first sent string is determined as the target sending length; or, when the number of characters in multiple first sent strings changes in an increasing manner, the number of characters in the first sent string adjacent to the target first sent string is determined as the target sending length.

[0065] Exemplarily, when the number of characters in multiple first sent strings changes in a decreasing manner, the computer device determines the number of characters in the first sent string adjacent to the target first sent string as the target sending length; or, when the number of characters in multiple first sent strings changes in an increasing manner, the computer device determines the number of characters in the first sent string adjacent to the target first sent string as the target sending length.

[0066] In this embodiment, when the number of characters of multiple first transmission strings changes in a decreasing manner, the number of characters of the first transmission string adjacent to the target first transmission string is slightly smaller than the number of characters of the target first transmission string. Therefore, the number of characters of the first transmission string adjacent to the target first transmission string is determined as the target transmission length; when the number of characters of multiple first transmission strings changes in an increasing manner, the number of characters of the first transmission string adjacent to the target first transmission string is slightly smaller than the number of characters of the target first transmission string. Therefore, the number of characters of the first transmission string adjacent to the target first transmission string is determined as the target transmission length; the target transmission length determined by the above method not only makes the target transmission length smaller than the maximum number of characters allowed to be received by the receiving performance of the computer device, but also avoids the target transmission length from being too small in number of characters, thereby improving the accuracy of the target transmission length.

[0067] In one embodiment, before receiving a plurality of second transmission character strings transmitted by the code reader based on the candidate time interval of the orientation change to obtain the second reception character string, the method further includes:

[0068] The target transmission length is transmitted to the code reader; and a plurality of second transmission character strings having the target transmission length as the number of characters are generated by the code reader.

[0069] Exemplarily, after determining the target sending length, the computer device sends the target sending length to the code reader, and the code reader generates multiple second sending character strings with the number of characters equal to the target sending length based on the number of multiple candidate time intervals; the number of the multiple second sending character strings is equal to the number of the multiple candidate time intervals.

[0070] In this embodiment, after determining the target sending length, the computer device sends the target sending length to the code reader in order to further determine the target sending time interval. The code reader generates a second sending character string with a plurality of characters used to determine the target sending time interval as the target sending length, thereby providing basic data for the subsequent determination of the target sending time interval.

[0071] In one embodiment, determining a target sending time interval from a plurality of candidate time intervals based on a plurality of second sending character strings and a second receiving character string includes:

[0072] Based on the dividing characters in the second received character string, the second received character string is divided into multiple second sub-strings; in the order of the interval lengths of the multiple candidate time intervals from long to short, the second sent character string corresponding to the candidate time interval is compared with the multiple second sub-strings in turn; when there is no second sub-string that is the same as the target second sent character string, the target sending time interval is determined based on the target second sent character string.

[0073] The second substring refers to a string consisting of some consecutive characters in the second received string.

[0074] Exemplarily, the computer device divides the second received string into multiple second substrings based on the dividing characters in the second received string, obtains the current second sent string in order of the interval lengths of multiple candidate time intervals from long to short, compares the current second sent string with the multiple second substrings, and when there is a second substring that is identical to the current second sent string, determines the next second sent string of the current second sent string as the updated current second sent string, repeats the step of comparing the current second sent string with the multiple second substrings until there is no second substring that is identical to the current second sent string, determines the current second sent string as the target second sent string, and determines the target sending time interval based on the directional change trend of the number of characters of the target second sent string and the multiple second sent strings.

[0075] In this embodiment, the second received string is divided into multiple second substrings by dividing characters in the second received string, some of the second substrings are complete second sent strings, and some of the second substrings are incomplete second sent strings. When there is no second substring that is identical to the target second sent string, it indicates that the computer device cannot completely receive the target second sent string within the candidate time interval corresponding to the target second sent string, and then the candidate time interval slightly longer than the candidate time interval corresponding to the target second sent string can be determined as the target sending time interval, thereby realizing the automation of the target sending time interval, thereby improving the efficiency of determining the target sending time interval in the code reader sending parameters.

[0076] In one embodiment, determining the target sending time interval based on the second sending character string includes:

[0077] When the interval lengths of multiple candidate time intervals change in an increasing manner, the candidate time interval corresponding to the second sending string adjacent to the target second sending string is determined as the target sending time interval; or, when the interval lengths of multiple candidate time intervals change in a decreasing manner, the candidate time interval corresponding to the second sending string adjacent to the target second sending string is determined as the target sending time interval.

[0078] Exemplarily, when the interval durations of multiple candidate time intervals change in an increasing manner, the computer device determines the candidate time interval corresponding to the second sending string adjacent to the target second sending string as the target sending time interval; or, when the interval durations of multiple candidate time intervals change in a decreasing manner, the computer device determines the candidate time interval corresponding to the second sending string adjacent to the target second sending string as the target sending time interval.

[0079] In this embodiment, when the interval lengths of multiple candidate time intervals are increasing, the candidate time interval corresponding to the second sending string adjacent to the target second sending string is slightly longer than the candidate time interval corresponding to the target second sending string. Therefore, the candidate time interval corresponding to the second sending string adjacent to the target second sending string is determined as the target sending time interval; or, when the interval lengths of multiple candidate time intervals are decreasing, the candidate time interval corresponding to the second sending string adjacent to the previous target second sending string is slightly longer than the candidate time interval corresponding to the target second sending string. Therefore, the candidate time interval corresponding to the second sending string adjacent to the previous target second sending string is determined as the target sending time interval; the target sending time interval determined by the above method not only makes the target sending time interval greater than the shortest time interval required for the computer device's receiving performance to receive a string of the target sending length, but also avoids the target sending time interval being too long, thereby improving the accuracy of the target sending time interval.

[0080] In one embodiment, before receiving a plurality of first sent character strings sent by a code reader based on a preset time interval to obtain a first received character string, the method further includes:

[0081] In response to the triggering operation of the parameter determination control of the code reader, the code reader is controlled to enter the parameter determination mode; a text receiving box is displayed, and the input cursor is controlled to be located in the text receiving box.

[0082] The barcode reader transmission parameter determination control refers to a control that controls the barcode reader to enter the transmission parameter determination mode. The barcode reader transmission parameter determination control can be a virtual control or a physical control, which is not limited here. The text receiving box refers to an area used to display received characters. The input cursor refers to an icon that represents the current input position. The input cursor can be a flashing vertical line.

[0083] Exemplarily, the debugger starts the code reader sending parameter debugging system in the computer device, the debugger clicks the code reader sending parameter determination control in the code reader sending parameter debugging system, the computer device responds to the triggering operation of the code reader sending parameter determination control, controls the code reader to enter the sending parameter determination mode, displays a text receiving box on the display screen of the computer device, controls the input cursor to be located in the text receiving box, and the text receiving box is used to display the characters received from the code reader.

[0084] In one embodiment, after displaying the text receiving box, controlling the input cursor to be located behind the text receiving box, further comprising: resetting the input method of the computer device to English and turning off uppercase letters. By setting the input method to English and turning off uppercase letters, it is avoided that the computer device receives the character string sent by the code reader and the uppercase letters and lowercase letters are confused, thereby causing errors in determining the parameters sent by the code reader.

[0085] In one embodiment, when the text receiving box is displayed, the input cursor is controlled to be located behind the text receiving box, and a prompt message is displayed. The prompt message is used to prompt not to operate the keyboard and mouse, for example, the prompt message is "the input method has been reset, please do not operate the keyboard or mouse until the interface display debugging is completed".

[0086] In this embodiment, the computer device controls the code reader to enter the sending parameter determination mode in response to the triggering operation of the code reader sending parameter determination control, so that the code reader performs actions related to the code reader sending parameter determination. The computer device displays a text receiving box and controls the input cursor to be located in the text receiving box for displaying the characters received from the code reader.

[0087] In an exemplary embodiment, the flowchart of determining the parameters sent by the code reader is as follows: Figure 5 As shown, including:

[0088] The debugger starts the code reader sending parameter debugging system in the computer device. The debugger clicks the code reader sending parameter determination control in the code reader sending parameter debugging system. The computer device responds to the triggering operation of the code reader sending parameter determination control, controls the code reader to enter the sending parameter determination mode, displays a text receiving box on the display screen of the computer device, controls the input cursor to be located in the text receiving box, resets the input method of the computer device to English, turns off uppercase, and displays a prompt message "The input method has been reset. Please do not operate the keyboard or mouse until the interface shows that debugging is completed."

[0089] After entering the sending parameter determination mode, the code reader sends a first sending character string and a line break to the computer device at preset time intervals (200 milliseconds) in the order in which the number of characters in the multiple first sending character strings increases. The computer device displays the received characters in the text receiving box. If no characters are received within the preset waiting time (5 seconds), the character sequence in the text receiving box is determined as the first receiving character string.

[0090] The computer device divides the first received string into multiple first substrings according to the line break in the first received string, obtains the current first sent string in the order of the number of characters from short to long, compares the current first sent string with the multiple first substrings, and when there is a first substring identical to the current first sent string, determines the next first sent string of the current first sent string as the updated current first sent string, repeats the step of comparing the current first sent string with the multiple first substrings until there is no first substring identical to the current first sent string, determines the current first sent string as the target first sent string, and determines the number of characters of the previous adjacent first sent string of the target first sent string as the target sent length. The computer device sets the sending length of the code reader to the target sending length, and records the first received string and the target sending length in the target record file.

[0091] After determining the target transmission length, the computer device sends the target transmission length to the code reader. Based on the number of multiple candidate time intervals, the code reader generates multiple second transmission character strings with the number of characters equal to the target transmission length, and sends a second transmission character string to the computer device every other candidate time interval in the descending order of the interval lengths of the multiple candidate time intervals. The computer device displays the received characters in the text receiving box. If no characters are received within the preset waiting time (5 seconds), the character sequence in the text receiving box is determined as the second receiving character string.

[0092] The computer device divides the second received string into multiple second substrings based on the line break in the second received string, obtains the current second sent string in the order of the interval lengths of multiple candidate time intervals from long to short, compares the current second sent string with the multiple second substrings, and when there is a second substring identical to the current second sent string, determines the next second sent string of the current second sent string as the updated current second sent string, repeats the step of comparing the current second sent string with the multiple second substrings until there is no second substring identical to the current second sent string, determines the current second sent string as the target second sent string, and determines the candidate time interval corresponding to the previous adjacent second sent string of the target second sent string as the target sending time interval. The computer device sets the sending time interval of the code reader as the target sending time interval, and records the second received string and the determined target sending time interval in the target record file.

[0093] In the above-mentioned method for determining the sending parameters of the code reader, a plurality of first sending strings sent by the code reader based on a preset time interval are received to obtain a first receiving string. Through the plurality of first sending strings and the first receiving string, the longest string that can be received by the computer device within the preset time interval can be determined, thereby determining a target sending length that matches the receiving performance of the computer device; a plurality of second sending strings sent by the code reader based on a plurality of candidate time intervals are received to obtain a second receiving string. Through the plurality of second sending strings and the second receiving string, the shortest time interval required for the computer device to receive a string of the target sending length can be determined, thereby determining the target sending time interval, that is, the determination of the sending parameters of the code reader can be completed through the computer device and the code reader, and the automation of the determination of the sending parameters of the code reader is realized, thereby improving the efficiency of determining the sending parameters of the code reader.
