[0046] In order to make the objectives, technical solutions and advantages of the present application more clear, the present application will be further described in detail below with reference to the 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.

[0047] In one embodiment, as Figure 1As shown Figure 1 is a schematic flowchart of a communication control method for a communication system in an embodiment; the communication system includes a master control end and an LED display screen; the master control end is communicatively connected to the LED display screen; the communication control method of the communication system, which is applied to the master control end of the communication system, includes the following steps:

[0048] Step S101, obtain the historical communication data of the LED display screen and the display control data to be sent.

[0049] Among them, the LED display screen includes at least one LED display module; the LED display module includes a plurality of drive circuits connected in series or in cascade or in parallel; each drive circuit is connected to and drives one or more LED lights; the drive circuit is used to perform display control on the LEDs connected thereto according to the display control data.

[0050] Among them, the historical communication data includes historical display control data and historical flag bit data; among them, the historical display control data refers to the display control data that has been completed and sent; the historical display control data includes one or more sent display control data; among them, the display control data can be composed of a binary coding group; for example, the display control data is 00000001. It can be understood that the display control data is used to perform display control on the LEDs connected to the drive circuit corresponding to the LED display screen. The display control data needs to be set according to the actual display control requirements and is not specifically limited here.

[0051] Among them, the historical flag bit data includes historical flag bits corresponding one by one to one or more sent display control data; the historical flag bit is a binary coding used to represent the type of historical coding obtained after encoding conversion of the sent display control data; among them, the type of historical coding includes the original data type and the complementary code data type. Among them, the original data type means that the historical coding is exactly the same as the sent display control data; the complementary code data type means that the historical coding and the sent display control data are complementary codes to each other. For example, assuming that the historical flag bit is "1", it is used to indicate that the type of historical coding obtained after encoding conversion of the sent display control data is the complementary code data type; assuming that the historical flag bit is "0", it is used to indicate that the type of historical coding obtained after encoding conversion of the sent display control data is the original data type.

[0052] Among them, the display control data to be sent refers to the next set of display control data to be sent to the drive circuit corresponding to the LED display screen.

[0053] Step S102, when the communication coding ratio of the historical communication data does not meet the preset coding ratio, determine the ratio abnormal type corresponding to the communication coding ratio.

[0054] Among them, the communication coding ratio refers to the ratio of the first cumulative total corresponding to the first coding to the second cumulative total corresponding to the second coding in the historical communication data; among them, the first coding and the second coding are complementary codes to each other; for example, if the first coding is "0", then the second coding is "1"; if the first coding is "1", then the second coding is "0". Among them, the first coding cumulative total refers to the sum of the cumulative quantities of the first coding in the historical communication data; the second coding cumulative total refers to the sum of the cumulative quantities of the second coding in the historical communication data.

[0055] It can be understood that since the historical communication data will be dynamically updated accordingly according to the actual communication control process, the first cumulative total corresponding to the first coding and the second cumulative total corresponding to the second coding will be updated accordingly with the update of the historical communication data, and thus the communication coding ratio of the historical communication data will also change accordingly with the passage of time; based on this, by comparing the communication coding ratio with the preset coding ratio, it is possible to determine in real time whether there is an imbalance between the first coding and the second coding during the communication process, so as to adjust the coding in a timely manner to ensure the balance of the communication coding ratio, that is, the ratio of the first coding and the second coding.

[0056] Among them, the preset coding ratio needs to be set according to the actual communication requirements and is not specifically limited here. In an exemplary embodiment, the preset coding ratio can be a preset ratio threshold; the preset ratio threshold is a specific value; for example, the preset ratio threshold can be set to 1; in another embodiment, the preset coding ratio can be a preset ratio range; the preset ratio range is a numerical interval; for example, the preset ratio range can be set to 0.9 - 1.1.

[0057] Among them, the ratio anomaly type includes the first anomaly type and the second anomaly type; among them, the first anomaly type refers to the situation where the first cumulative total of the first coding is excessive; the second anomaly type refers to the situation where the second cumulative total of the second coding is excessive.

[0058] It can be understood that for different ratio anomaly types, appropriate coding conversion strategies need to be selected to ensure as much as possible the balance of the communication coding ratio during the communication process, and thus ensure the stability and reliability during the communication process of the communication system.

[0059] Step S103, perform coding conversion on the display control data to be sent according to the ratio anomaly type to obtain the target coding.

[0060] Among them, the target coding can be the original binary coding group corresponding to the display control data to be sent, or the complementary code of the original binary coding group corresponding to the display control data to be sent; it can be understood that the specific type of the target coding needs to be determined according to the ratio anomaly type and is not specifically limited here.

[0061] Step S104, perform communication control on the driving circuit corresponding to the LED display screen according to the target code.

[0062] Exemplarily, obtain the historical communication data corresponding to the LED display screen and the next set of display control data to be sent; based on the historical communication data, determine the communication coding ratio corresponding to the historical communication data, and determine whether the communication coding ratio meets the preset coding ratio; specifically, in the case where the communication coding ratio of the historical communication data does not meet the preset coding ratio, determine the ratio anomaly type corresponding to the communication coding ratio; furthermore, according to the ratio anomaly type, determine the coding conversion strategy corresponding to the ratio anomaly type, and perform corresponding coding conversion on the display control data to be sent according to the coding conversion strategy to obtain the corresponding target code; finally, perform communication control on the driving circuit corresponding to the LED display screen based on the target code.

[0063] In this embodiment, based on the historical communication data, the change trend of the communication coding ratio during the communication process can be accurately identified; furthermore, in the case where the communication coding ratio of the historical communication data does not meet the preset coding ratio, the ratio anomaly type corresponding to the communication coding ratio can be accurately determined; based on the ratio anomaly type, perform coding conversion on the display control data to be sent to obtain the target code to ensure the balance of the communication coding ratio during the communication control process; perform communication control on the driving circuit corresponding to the LED display screen according to the target code; based on this, by analyzing the communication coding ratio of the historical communication data in real time, the corresponding coding conversion can be timely performed on the display control data to be sent to obtain the target code, improving the balance of the communication coding ratio, effectively avoiding the problem of poor communication stability of the communication system caused by the coding ratio imbalance in the prior art, and improving the stability of the communication process of the communication system.

[0064] In one embodiment, as Figure 2 shown, Figure 2 is a flowchart of the steps of the communication coding ratio determination method in one embodiment; the method for determining the communication coding ratio of historical communication data includes the following steps:

[0065] Step S201, determine the cumulative coding total according to the historical communication data.

[0066] Among them, the historical communication data includes historical display control data and historical flag bit data; among them, the historical display control data includes one or more sent display control data; the display control data is composed of binary coding groups; the historical flag bit data includes historical flag bits corresponding one-to-one to one or more sent display control data; the historical flag bit is binary coding.

[0067] Among them, the cumulative coding total refers to the sum of all binary codes contained in historical communication data; that is, the cumulative coding total is equal to the sum of the binary coding total corresponding to historical display control data and the binary coding total corresponding to historical flag bit data.

[0068] Step S202: Determine the first cumulative total corresponding to the first code and the second cumulative total corresponding to the second code according to the cumulative coding total.

[0069] Among them, the first code and the second code are complementary codes to each other. The first code cumulative total refers to the sum of the cumulative quantities of the first code in historical communication data; the second code cumulative total refers to the sum of the cumulative quantities of the second code in historical communication data.

[0070] Step S203: Determine the communication coding ratio according to the ratio of the first cumulative total to the second cumulative total.

[0071] Among them, the communication coding ratio refers to the ratio of the first cumulative total to the second cumulative total; that is, the communication coding ratio = the first cumulative total / the second cumulative total.

[0072] Exemplarily, according to historical communication data, calculate the sum of the binary coding total corresponding to historical display control data and the binary coding total corresponding to historical flag bit data in the historical communication data to obtain the cumulative coding total; according to the cumulative coding total, calculate the first cumulative total corresponding to the first code and the second cumulative total corresponding to the second code; and then calculate the communication coding ratio according to the ratio of the first cumulative total to the second cumulative total.

[0073] In this embodiment, based on the first cumulative total corresponding to the first code and the second cumulative total corresponding to the second code, the current communication coding ratio can be accurately determined, and then the change trend of the communication coding ratio can be grasped in a timely manner, laying a foundation for adjusting the coding conversion strategy in a timely manner, and further laying a foundation for improving the stability in the communication process of the communication system.

[0074] In one embodiment, when the communication coding ratio of historical communication data does not meet the preset coding ratio, determining the ratio anomaly type corresponding to the communication coding ratio includes the following steps:

[0075] Step 1: If the communication coding ratio is greater than the first coding ratio, determine that the ratio anomaly type corresponding to the communication coding ratio is the first anomaly type.

[0076] Step 2: If the communication coding ratio is less than the second coding ratio, determine that the ratio anomaly type corresponding to the communication coding ratio is the second anomaly type.

[0077] Among them, the second coding ratio is equal to the first coding ratio, or the second coding ratio is less than the first coding ratio.

[0078] It should be noted that the first coding ratio and the second coding ratio are determined according to a preset coding ratio. When the preset coding ratio is a preset ratio threshold, i.e., a specific value, the first coding ratio is equal to the second coding ratio and equal to the preset ratio threshold; when the preset coding ratio is a preset ratio range, i.e., a numerical interval, the first coding ratio is equal to the upper bound of the preset ratio range, and the second coding ratio is equal to the lower bound of the preset ratio range. For example, when the preset ratio range is 0.9 - 1.1, the first coding ratio is equal to 1.1 and the second coding ratio is equal to 0.9; the second coding ratio is less than the first coding ratio.

[0079] Among them, the first abnormal type refers to the situation where the first cumulative total of the first coding is excessive; the second abnormal type refers to the situation where the second cumulative total of the second coding is excessive.

[0080] In an exemplary embodiment, taking the second coding ratio being equal to the first coding ratio as an example, if the communication coding ratio is equal to the first coding ratio, it is determined that the communication coding ratio is normal, and at this time, any coding conversion strategy can be selected for the display control data to be sent; if the communication coding ratio is greater than the first coding ratio, it is determined that the ratio abnormal type corresponding to the communication coding ratio is the first abnormal type, and at this time, a coding conversion strategy corresponding to the first abnormal type needs to be selected for the display control data to be sent; if the communication coding ratio is less than the second coding ratio, it is determined that the ratio abnormal type corresponding to the communication coding ratio is the second abnormal type, and at this time, a coding conversion strategy corresponding to the second abnormal type needs to be selected for the display control data to be sent.

[0081] In another exemplary embodiment, taking the second coding ratio being less than the first coding ratio as an example, if the communication coding ratio is between the second coding ratio and the first coding ratio, it is determined that the communication coding ratio is normal, and at this time, any coding conversion strategy can be selected for the display control data to be sent; if the communication coding ratio is greater than the first coding ratio, it is determined that the ratio abnormal type corresponding to the communication coding ratio is the first abnormal type, and at this time, a coding conversion strategy corresponding to the first abnormal type needs to be selected for the display control data to be sent; if the communication coding ratio is less than the second coding ratio, it is determined that the ratio abnormal type corresponding to the communication coding ratio is the second abnormal type, and at this time, a coding conversion strategy corresponding to the second abnormal type needs to be selected for the display control data to be sent.

[0082] It should be noted that the coding conversion strategy corresponding to the first abnormal type is different from the coding conversion strategy corresponding to the second abnormal type. The specific implementation method will be described in detail below and will not be elaborated here.

[0083] In this embodiment, based on the communication coding ratio, the first coding ratio, and the second coding ratio, the ratio anomaly type corresponding to the communication coding ratio can be accurately determined. Furthermore, based on the ratio anomaly type, the corresponding coding conversion strategy can be flexibly determined, improving the flexibility and stability of the communication process in the communication system.

[0084] In one embodiment, the ratio anomaly type includes a first anomaly type; encoding and converting the display control data to be sent according to the ratio anomaly type to obtain a target code, including the following steps:

[0085] Step 1, if the ratio anomaly type is the first anomaly type and the number of first codes in the display control data to be sent is greater than the number of second codes, then perform a complementary code conversion on the display control data to be sent to obtain the target complementary code corresponding to the display control data to be sent.

[0086] Step 2, use the target complementary code as the target code.

[0087] Step 3, if the ratio anomaly type is the first anomaly type and the number of first codes in the display control data to be sent is less than or equal to the number of second codes, then use the display control data to be sent as the target code.

[0088] It can be understood that this embodiment is the coding conversion strategy corresponding to the first anomaly type. When determining the coding conversion strategy corresponding to the first anomaly type, not only the ratio anomaly type needs to be considered, but also the quantity relationship between the first code and the second code in the display control data to be sent needs to be combined to ensure that the communication coding ratio can be adjusted timely and accurately based on the target code, ensuring the balance of the communication coding ratio.

[0089] Exemplarily, in the case where the proportion anomaly type is the first anomaly type, that is, when there is an excess in the first cumulative total of the first encoding, if the number of the first encodings in the display control data to be sent is greater than the number of the second encodings, the display control data to be sent is subjected to an inverse code conversion to obtain the target inverse code corresponding to the display control data to be sent, and the target inverse code is used as the target encoding; if the number of the first encodings in the display control data to be sent is less than or equal to the number of the second encodings, the display control data to be sent is used as the target encoding. For example, assuming that the first encoding is "1" and the second encoding is "0", in the case where the proportion anomaly type is the first anomaly type, that is, when there is an excess in the first cumulative total of the first encoding "1", if the display control data to be sent is "11111000", the display control data "11111000" to be sent is subjected to an inverse code conversion to obtain the target inverse code "00000111", and the target inverse code "00000111" is used as the target encoding, that is, the target encoding is "00000111"; if the display control data to be sent is "00000011", the display control data to be sent is used as the target encoding, that is, the target encoding is "00000011".

[0090] In this embodiment, an encoding conversion strategy corresponding to the first anomaly type is provided. The encoding conversion strategy corresponding to the first anomaly type not only considers the proportion anomaly type, but also combines the quantity relationship between the first encoding and the second encoding in the display control data to be sent, ensuring that the communication encoding proportion can be adjusted timely and accurately based on the target encoding, and further ensuring the balance of the communication encoding proportion.

[0091] In one embodiment, the proportion anomaly type includes a second anomaly type; encoding the display control data to be sent according to the proportion anomaly type to obtain the target encoding includes the following steps:

[0092] Step 1, if the proportion anomaly type is the second anomaly type and the number of the first encodings in the display control data to be sent is less than the number of the second encodings, the display control data to be sent is subjected to an inverse code conversion to obtain the target inverse code corresponding to the display control data to be sent.

[0093] Step 2, using the target inverse code as the target encoding.

[0094] Step 3, if the proportion anomaly type is the second anomaly type and the number of the first encodings in the display control data to be sent is greater than or equal to the number of the second encodings, the display control data to be sent is used as the target encoding.

[0095] It can be understood that this embodiment is the encoding conversion strategy corresponding to the second abnormal type. When determining the encoding conversion strategy corresponding to the second abnormal type, not only the proportional abnormal type needs to be considered, but also the quantitative relationship between the first encoding and the second encoding in the display control data to be sent needs to be combined to ensure that the communication encoding ratio can be adjusted timely and accurately based on the target encoding, and to ensure the balance of the communication encoding ratio.

[0096] Exemplarily, when the proportional abnormal type is the second abnormal type, that is, when the second cumulative total of the second encoding is excessive, if the number of the first encoding in the display control data to be sent is less than the number of the second encoding, then perform an inverse code conversion on the display control data to be sent to obtain the target inverse code corresponding to the display control data to be sent, and use the target inverse code as the target encoding; if the number of the first encoding in the display control data to be sent is greater than or equal to the number of the second encoding, then use the display control data to be sent as the target encoding. For example, assume that the first encoding is "1" and the second encoding is "0". When the proportional abnormal type is the second abnormal type, that is, when the second cumulative total of the second encoding "0" is excessive, if the display control data to be sent is "00000001", then perform an inverse code conversion on the display control data "00000001" to obtain the target inverse code "11111110", and use the target inverse code "11111110" as the target encoding, that is, the target encoding is "11111110"; if the display control data to be sent is "11111100", then use the display control data to be sent as the target encoding, that is, the target encoding is "11111100".

[0097] In this embodiment, an encoding conversion strategy corresponding to the second abnormal type is provided. The encoding conversion strategy corresponding to the second abnormal type not only considers the proportional abnormal type, but also combines the quantitative relationship between the first encoding and the second encoding in the display control data to be sent, ensuring that the communication encoding ratio can be adjusted timely and accurately based on the target encoding, and thus ensuring the balance of the communication encoding ratio.

[0098] In one embodiment, as Figure 3 shown, Figure 3 is a schematic flowchart of the steps of a communication control method according to the target encoding in one embodiment; performing communication control on the drive circuit corresponding to the LED display screen according to the target encoding includes the following steps:

[0099] Step S301, compare the display control data to be sent with the target encoding to determine the target flag bit.

[0100] Step S302, perform communication control on the drive circuit corresponding to the LED display screen according to the target encoding and the target flag bit.

[0101] Among them, the target flag bit includes a first flag bit or a second flag bit; among them, the first flag bit and the second flag bit are complementary codes to each other. Exemplarily, if the first flag bit is "1", then the second flag bit is "0"; if the first flag bit is "0", then the second flag bit is "1".

[0102] It should be noted that the target flag bit is used to mark the type of the target code, so that the corresponding driving circuit can obtain accurate display control data according to the target flag bit. The type of the target code includes the original data type and the complementary code data type. Among them, the original data type means that the target code is exactly the same as the display control data to be sent; the complementary code data type means that the target code and the display control data to be sent are complementary codes to each other. Specifically, the first flag bit is used to mark that the type of the target code is the original data type; the second flag bit is used to mark that the type of the target code is the complementary code data type.

[0103] Exemplarily, after obtaining the target code, compare the display control data to be sent with the target code to determine the corresponding target flag bit, and then communicate and control the driving circuit corresponding to the LED display screen according to the target code and the target flag bit to ensure that the driving circuit can accurately obtain the corresponding display control data.

[0104] In this embodiment, based on the target flag bit, it can be ensured that the driving circuit corresponding to the LED display screen accurately obtains the corresponding display control data, improving the accuracy and reliability of communication control.

[0105] In one embodiment, comparing the display control data to be sent with the target code to determine the target flag bit includes the following steps:

[0106] Step 1, if the target code is the same as the display control data to be sent, generate a first flag bit.

[0107] Step 2, if the target code is different from the display control data to be sent, generate a second flag bit.

[0108] Among them, the second flag bit and the first flag bit are complementary codes to each other. Among them, the first flag bit is used to mark that the type of the target code is the original data type; the second flag bit is used to mark that the type of the target code is the complementary code data type.

[0109] Step 3, obtain the target flag bit according to the first flag bit or the second flag bit.

[0110] Exemplarily, the display control data to be sent is compared with the target code. If the target code is the same as the display control data to be sent, a first flag bit is generated and the first flag bit is used as the target flag bit. If the target code is different from the display control data to be sent, a second flag bit is generated and the second flag bit is used as the target flag bit. For example, assume that "1" indicates that the target code is the same as the display control data to be sent, and "0" indicates that the target code is different from the display control data to be sent. Taking the display control data to be sent as "00000001" as an example, if the target code is "00000001", at this time the target code is the same as the display control data to be sent, a first flag bit is generated, and the first flag bit is "1". Then the first flag bit "1" is used as the target flag bit to mark that the type of the target code is the original data type. If the target code is "11111110", at this time the target code is different from the display control data to be sent, a second flag bit is generated, and the second flag bit is "0". Then the second flag bit "0" is used as the target flag bit to mark that the type of the target code is the complementary code data type.

[0111] In this embodiment, by comparing the display control data to be sent with the target code, the target flag bit can be accurately determined, laying a foundation for improving the reliability and accuracy of the communication process of the communication system.

[0112] In one embodiment, according to the target code and the target flag bit, communication control is performed on the driving circuit corresponding to the LED display screen, including the following steps:

[0113] Step 1, according to the preset rule, a target data packet is generated based on the target code and the target flag bit.

[0114] Step 2, according to the target data packet, communication control is performed on the driving circuit corresponding to the LED display screen.

[0115] Among them, the preset rule needs to be set according to the actual communication control requirements and is not specifically limited here. It should be noted that the preset rule determines the data structure corresponding to the target data packet. For example, the preset rule can determine the target data packet in the form of "target code + target flag bit", or the preset rule can also determine the target data packet in the form of "target flag bit + target code".

[0116] Exemplarily, assume that the target encoding is "00000011" and the target flag bit is "1". If following the preset rule of "target encoding + target flag bit", then according to the target encoding and the target flag bit, the generated target data packet is "00000011-1"; if following the preset rule of "target flag bit + target encoding", then according to the target encoding and the target flag bit, the generated target data packet is "1-00000011". Then, the target data packet is sent to the driving circuit corresponding to the LED display screen to achieve the communication control of the corresponding driving circuit. It can be understood that the driving circuit can parse out the correct display control data according to the target flag bit in the target data packet.

[0117] In this embodiment, based on the preset rule, the data structure corresponding to the target data packet can be accurately determined. Furthermore, based on the target data packet, the driving circuit can accurately parse out the corresponding display control data according to the target flag bit in the target data packet, improving the reliability and accuracy of the communication control.

[0118] In a specific embodiment, assume that the 4 groups of display control data corresponding to the LED display screen are "00000001", "00000010", "00000011", "00000100"; the first encoding is "0"; the second encoding is "1"; assume that the preset encoding ratio is 1; and assume that the target flag bit is "0", indicating that the type of the target encoding is the original data type; the target flag bit is "1", indicating that the type of the target encoding is the complementary code data type; the preset rule is "target flag bit + target encoding"; the main control end of the communication system can obtain 4 groups of target data packets, namely "0-00000001", "1-11111101", "0-00000011", "1-11111011", according to the 4 groups of display control data and the communication control method described in the above embodiment. Based on this, the balance of the communication coding ratio in the communication process can be ensured, improving the reliability and stability of the communication process.

[0119] Specifically, before sending the first set of display control data to be sent, i.e., "00000001", according to the historical communication data, it is determined that the cumulative coding total is 0, that is, the binary coding totals corresponding to the historical display control data and the historical flag bit data are both 0. At this time, any coding conversion strategy can be used to perform coding conversion on the first set of display control data to be sent, i.e., "00000001". In this embodiment, an example is given where the target coding corresponding to the first set of display control data to be sent, i.e., "00000001", is "00000001". According to the target coding "00000001" and the first set of display control data to be sent, i.e., "00000001", the target flag bit can be determined to be "0"; furthermore, according to the preset rule "target flag bit + target coding", the target data packet can be determined to be "0-00000001". According to the target data packet "0-00000001", communication control is performed on the drive circuit corresponding to the first set of display control data in the LED display screen. Thus, the sending of the first set of display control data to be sent is completed.

[0120] Similarly, before sending the second set of display control data to be sent, i.e., "00000010", according to the historical communication data "0-00000001", it is determined that the cumulative coding total is 9, that is, the binary coding total corresponding to the historical display control data is 8, and the binary coding total corresponding to the historical flag bit data is 1. Among them, the first cumulative total of the first coding "0" is 8, and the second cumulative total of the second coding "1" is 1. Furthermore, the communication coding ratio is determined to be 8 / 1 = 8; since the communication coding ratio 8 is greater than the preset coding ratio 1, the ratio anomaly type is determined to be the first anomaly type, that is, the first coding "0" is excessive; furthermore, according to the second set of display control data to be sent, i.e., "00000010", it is determined that the number of the first coding "0" is greater than the number of the second coding "1". At this time, the second set of display control data to be sent, i.e., "00000010", needs to be inverted to obtain the target inverse code "11111101", and the target inverse code "11111101" is used as the target coding; furthermore, according to the target coding "11111101" and the second set of display control data to be sent, i.e., "00000010", the target flag bit can be determined to be "1"; according to the preset rule "target flag bit + target coding", the target data packet can be determined to be "1-11111101". According to the target data packet "1-11111101", communication control is performed on the drive circuit corresponding to the second set of display control data in the LED display screen. Thus, the sending of the second set of display control data to be sent is completed. By analogy, according to the above implementation process, the sending of the third and fourth sets of display control data to be sent is completed in sequence, which will not be elaborated here.

[0121] The communication control method of the above communication system obtains the historical communication data of the LED display screen and the display control data to be sent; based on the historical communication data, it can accurately identify the change trend of the communication coding ratio during the communication process; furthermore, when the communication coding ratio of the historical communication data does not meet the preset coding ratio, it can accurately determine the ratio anomaly type corresponding to the communication coding ratio; based on the ratio anomaly type, the display control data to be sent is encoded and converted to obtain the target code to ensure the balance of the communication coding ratio during the communication control process; the driving circuit corresponding to the LED display screen is controlled for communication according to the target code; based on this, by analyzing the communication coding ratio of the historical communication data in real time, the display control data to be sent can be encoded and converted accordingly in a timely manner to obtain the target code, improving the balance of the communication coding ratio and effectively avoiding the problem of poor communication stability of the communication system caused by coding ratio imbalance in the prior art, and improving the stability of the communication process of the communication system.
