[0058] 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.

For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to the specific circumstances. In addition, in the description of the present application, unless otherwise specified, "plurality" refers to two or more. "And" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and B can represent: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the previously associated objects are in an "or" relationship.

[0060] The data processing method provided in the embodiment of the present application can be applied to Figure 1 In the application environment shown. Among them, the printing device 10 establishes communication connections with multiple terminals (terminal 21, terminal 22, terminal 23... in the figure) through a communication network, and after establishing a communication connection with each terminal, allocates a first memory space associated with its connection identifier to each terminal. After establishing a communication connection with each terminal, the printing device 10 can receive the instruction data sent by each terminal in real time through an external wireless communication module, and store each instruction data in the corresponding first memory space according to the connection identifier of each terminal carried by each instruction data. Subsequently, the printing device 10 will periodically traverse each block of the first memory space. When traversing to the first memory space corresponding to any terminal, the printing device performs processing according to the instruction data sent by the terminal.

[0061] It is worth noting that the terminal that establishes a communication connection with the printing device 10 may be, but is not limited to, various smart phones, tablet computers, personal computers, laptop computers, Internet of Things devices and portable wearable devices. The Internet of Things devices may be smart speakers, smart TVs, smart air conditioners, smart car-mounted devices, etc. Portable wearable devices may be smart watches, smart bracelets, head-mounted devices, etc. The connection identifier may be, but is not limited to, a handle, etc. The wireless communication module may be, but is not limited to, a Bluetooth communication module, a WiFi communication module, etc. The printing device 10 is hardware-connected to the wireless communication module via a serial port, so as to receive the command data sent by each terminal in real time.

[0062] In one embodiment, Figure 2 As shown, a data processing method is provided, which is applied to Figure 1 The printing device 10 in the embodiment is taken as an example to illustrate, and the following steps are included:

[0063] S201: establishing communication connections with a plurality of terminals respectively, and allocating a first memory space to each terminal after establishing the communication connection with each terminal; each first memory space is associated with a connection identifier of each terminal.

[0064] The first memory space may be, but is not limited to, a ring buffer in the memory. The connection identifier of each terminal may be, but is not limited to, a handle identifier of each terminal.

[0065] Optionally, the printing device 10 establishes communication connections with multiple terminals respectively through the wireless communication module, and after establishing the communication connection with each terminal, allocates a different ring buffer to each terminal for storing data subsequently sent by the terminal.

[0066] Specifically, after the printing device 10 establishes a communication connection with any terminal through the wireless communication module, the wireless communication module immediately reports a connection event including the terminal handle identifier to the MCU of the printing device 10. After receiving the connection event, the MCU of the printing device 10 allocates an independent ring buffer for the corresponding terminal according to the handle identifier in the connection event, and the ring buffer is associated with the handle identifier in the connection event.

[0067] It is understandable that in the early stage of establishing a communication connection between the terminal and the printing device 10, the communication interaction between the two is mainly to confirm the connection status or set printing-related parameters, rather than to transmit a large amount of actual data (such as printing data). Therefore, in the early stage of establishing a communication connection between the terminal and the printing device 10, the amount of data exchanged between the two is relatively small, and the first memory space (such as a ring buffer) allocated to each terminal can also be set to be small, which can effectively save its memory resources without affecting the data processing performance of the printing device 10, thereby improving the data processing speed.

[0068] In this embodiment, the printing device establishes communication connections with multiple terminals respectively, and after establishing communication connections with each terminal, allocates a first memory space associated with the connection identifier to each terminal (such as each ring buffer in the memory), which can ensure that each terminal has a different independent memory space to store the data sent subsequently after establishing a communication connection with the printing device, ensuring that the data streams of different terminals are independent of each other and will not be confused. In addition, by reasonably allocating the size of the first memory space, the printing device effectively saves the memory resources of the printing device and improves the data processing speed of the printing device while ensuring that the first memory space can meet the actual data processing needs.

[0069] S202: Receive instruction data sent by each terminal; each instruction data carries a connection identifier of each terminal.

[0070] Optionally, the printing device 10 receives the instruction data sent by each terminal through the wireless communication module, and after receiving each instruction data, reports each instruction data and the connection identifier of each terminal carried by it to the MCU. It can be understood that the instruction data sent by each terminal carries the unique handle identifier corresponding to each terminal to ensure that the printing device 10 can distinguish and process instructions from different terminals.

[0071] Specifically, the instruction data may include, but is not limited to: start printing instruction data, print instruction data, status query instruction data, connection control instruction data, etc. The start printing instruction data is used to control the printing device to perform printing initialization. The print instruction data is used to set relevant parameters of the print task and control the start and stop of the print task. The status query instruction data is used to query the progress status of the print task. The connection control instruction is used to control the connection or disconnection of communication.

[0072] S203: storing each instruction data into a corresponding first memory space according to the connection identifier of each terminal.

[0073] Optionally, after receiving each instruction data, the MCU of the printing device 10 searches for the ring buffer of the corresponding terminal in the mapping table maintained internally according to the handle identifier carried by each instruction data, and then stores each instruction data in the corresponding found ring buffer.

[0074] In this embodiment, the printing device receives the command data sent by each terminal, and after receiving the command data sent by each terminal, stores each command data in the corresponding first memory space according to the connection identifier of each terminal carried by each command data, which helps to distinguish the command data from different terminals through partitioned storage management.

[0075] S204: When traversing to a first memory space corresponding to any one of the multiple terminals, execute processing according to instruction data sent by any one of the terminals.

[0076] Optionally, the MCU of the printing device 10 traverses the ring buffer allocated to each terminal in the memory (i.e., the ring buffer associated with the handle identifier of each terminal), and each time it traverses to a ring buffer, it determines whether the ring buffer stores data to be parsed. If the ring buffer stores data to be parsed, the corresponding data is taken out for parsing, and the handle identifier corresponding to the ring buffer is recorded. After the complete instruction data is parsed, the corresponding processing is performed according to the parsed instruction data and the recorded handle identifier.

[0077] Specifically, if the instruction data parsed from the ring buffer by the MCU of the printing device 10 includes the start printing instruction data, the MCU allocates a larger ring buffer to the corresponding terminal according to the handle identifier corresponding to the ring buffer to store the printing data to be sent by the terminal later; after the printing is completed, the status information of the printing task is fed back to the corresponding terminal, and a smaller ring buffer is reallocated to the terminal. The smaller ring buffer can be consistent with the ring buffer size set when it was initially allocated to save memory space. If the instruction data parsed from the ring buffer by the MCU of the printing device 10 does not include the start printing instruction data, the MCU executes the corresponding instruction task according to the instruction data, and feeds back the status information of the instruction task to the corresponding terminal according to the handle identifier corresponding to the ring buffer.

[0078] In this embodiment, the printing device traverses the circular buffer allocated to multiple terminals in the memory, and when traversing to the first memory space corresponding to any one of the multiple terminals, performs processing according to the data to be parsed stored in the first memory space (that is, the instruction data most recently sent by any terminal). This can ensure that in a scenario where multiple terminals are connected at the same time, data from different devices can be correctly processed to provide users with stable services.

[0079] In the above data processing method, the printing device establishes communication connections with multiple terminals respectively, and after establishing communication connections with each terminal, allocates a first memory space associated with the connection identifier to each terminal, which can ensure that each terminal can have a different independent memory space to store the subsequently sent data after establishing communication connection with the printing device, ensuring that the data streams of different terminals are independent of each other and will not be confused; by reasonably allocating the size of the first memory space, while ensuring that the first memory space can meet the actual data processing needs, the memory resources of the printing device are effectively saved, and the data processing speed of the printing device is improved; by receiving the instruction data sent by each terminal, and after receiving the instruction data sent by each terminal, storing each instruction data in the corresponding first memory space according to the connection identifier of each terminal carried by each instruction data, it is helpful to distinguish the instruction data from different terminals through the partitioned storage management method; by traversing the ring buffer allocated to multiple terminals in the memory, when traversing to the first memory space corresponding to any one of the multiple terminals, executing processing according to the data to be parsed stored in the first memory space, it can ensure that in the scenario where multiple terminals are connected at the same time, the data from different devices are correctly processed, and stable services are provided to users. The above method can effectively classify, store and process the data received in the multi-connection state, avoid data confusion problems and improve the reliability of data processing.

[0080] In one embodiment, Figure 3 As shown, another data processing method is provided, which is applied to Figure 1 The printing device 10 in the embodiment is taken as an example to illustrate, and the following steps are included:

[0081] S301: establishing communication connections with a plurality of terminals respectively, and allocating a first memory space to each terminal after establishing the communication connection with each terminal.

[0082] Optionally, the printing device 10 establishes communication connections with multiple terminals respectively through the wireless communication module, and after establishing the communication connection with each terminal, allocates an independent first memory space to each terminal for storing data subsequently sent by the terminal. The first memory space may be, but is not limited to, a ring buffer in the memory. Each first memory space is associated with a connection identifier of each terminal. The connection identifier of each terminal may be, but is not limited to, a handle identifier of each terminal.

[0083] Specifically, after the printing device 10 establishes a communication connection with any terminal through the wireless communication module, the wireless communication module immediately reports a connection event including the terminal connection identifier (such as a handle identifier) ​​to the MCU of the printing device 10. After receiving the connection event, the MCU of the printing device 10 allocates a first memory space (such as a ring buffer) that is independent and associated with the connection identifier in the connection event to the corresponding terminal according to the connection identifier in the connection event.

[0084] It is understandable that in the early stage of establishing a communication connection between the terminal and the printing device 10, the communication interaction between the two is mainly to confirm the connection status or set printing-related parameters, rather than to transmit a large amount of printing data. Therefore, in the early stage of establishing a communication connection between the terminal and the printing device 10, the amount of data exchanged between the two is relatively small, and the first memory space allocated to each terminal can also be set to be small, which can effectively save its memory resources without affecting the data processing performance of the printing device 10, thereby improving the data processing speed.

[0085] S302: Receive instruction data sent by each terminal; each instruction data carries a connection identifier of each terminal.

[0086] Optionally, the printing device 10 receives the instruction data sent by each terminal through the wireless communication module, and after receiving each instruction data, reports each instruction data and the connection identifier of each terminal carried by it to the MCU. It can be understood that the instruction data sent by each terminal carries the unique connection identifier corresponding to each terminal to ensure that the printing device 10 can distinguish and process instructions from different terminals.

[0087] The command data may include, but is not limited to, start printing command data, print command data, status query command data, connection control command data, etc. The start printing command data is used to control the printing device to initialize printing. The print command data is used to set the relevant parameters of the print task and control the start and stop of the print task; the print command data may include, but is not limited to, print task setting command data, print task stop command data, etc. The print task setting command data is used to configure and set various parameters of the print task, such as paper size, print quality, double-sided printing, etc. The status query command data is used to query the progress status of the print task. The connection control command is used to control the connection or disconnection of communication.

[0088] S303: storing each instruction data into a corresponding first memory space according to the connection identifier of each terminal.

[0089] Optionally, after the MCU of the printing device 10 receives each instruction data, it searches the first memory space of the corresponding terminal in the mapping table maintained internally according to the connection identifier carried by each instruction data, and then stores each instruction data in the corresponding first memory space found, so that the instruction data from different terminals can be distinguished through partitioned storage management.

[0090] S304: When traversing to the first memory space corresponding to any terminal, determine whether the first memory space stores instruction data to be parsed. If yes, execute S305; if no, execute S317.

[0091] Optionally, when the MCU of the printing device 10 traverses to the first memory space corresponding to any one of the multiple terminals, it combines the read / write pointer and the status flag and other mechanisms to determine whether there is instruction data to be parsed in the first memory space. Specifically, the MCU can check the positions of the read pointer and the write pointer of the first memory space (such as the ring buffer). If they are not equal, it means that the instruction data to be parsed is stored in the first memory space; if they are equal, it means that the instruction data to be parsed is not stored in the first memory space. In addition, the MCU will also refer to the status flag to ensure that the same data is not processed repeatedly.

[0092] S305: parse the instruction data, and record the connection identifier corresponding to the first memory space.

[0093] Optionally, the printing device 10 parses the instruction data, and records the connection identifier corresponding to the first memory space based on a mapping table maintained internally.

[0094] S306: Determine whether the instruction data includes the start printing instruction data. If yes, execute S307; if no, execute S314.

[0095] It can be understood that the instruction data to be parsed stored in the first memory space includes the start printing instruction data, which means that after the printing device 10 performs printing initialization in response to the start printing instruction data, it will receive a large amount of printing data from the corresponding terminal. Therefore, in this case, the printing device 10 needs to reallocate a larger memory space (i.e., the second memory space hereinafter) to the terminal during the printing initialization process. The instruction data to be parsed stored in the first memory space does not include the start printing instruction data, which means that the printing device 10 will not transmit a large amount of printing data subsequently. Therefore, in this case, the printing device 10 can directly perform the corresponding printing task according to the instruction data.

[0096] Specifically, if the instruction data parsed from the first memory space by the MCU of the printing device 10 includes the start printing instruction data, the MCU allocates a larger second memory space to the corresponding terminal according to the connection identifier corresponding to the first memory space, so as to store the printing data to be sent by the terminal later; after the printing is completed, the status information of the printing task is fed back to the corresponding terminal, and a smaller memory space is reallocated to the terminal, and the smaller memory space can be the same size as the first memory space set when it was initially allocated, so as to save memory space. If the instruction data parsed from the first memory space by the MCU of the printing device 10 does not include the start printing instruction data, the MCU executes the corresponding instruction task according to the instruction data, and feeds back the status information of the instruction task to the corresponding terminal according to the connection identifier corresponding to the first memory space.

[0097] S307: reallocate the second memory space for the terminal according to the start printing instruction data.

[0098] Optionally, when the parsed instruction data includes start printing instruction data, the MCU of the printing device 10 reallocates the second memory space for the terminal according to the start printing instruction data. It can be understood that the second memory space is larger than the first memory space, and the second memory space can be but is not limited to a ring buffer in the memory, and the second memory space is associated with the connection identifier of any terminal.

[0099] S308: storing the print data sent by the terminal into the second memory space.

[0100] Optionally, after the MCU of the printing device 10 receives the print data sent by the terminal, it searches for the second memory space of the corresponding terminal in the mapping table maintained internally according to the connection identifier carried by the print data (such as the handle identifier of the terminal), and then stores the print data in the corresponding second memory space found, thereby preventing print data overflow.

[0101] S309: When traversing to the second memory space, executing a corresponding printing task according to the printing data.

[0102] Optionally, the MCU of the printing device 10 traverses the first memory space and the second memory space allocated to multiple terminals in the memory, and when traversing to the second memory space, parses the print data stored in the second memory space, and generates specific control instructions for the printing components or line-by-line print data based on the parsing results, and then executes the corresponding printing task according to the control instructions for the printing components or the print line data.

[0103] In one embodiment, after executing the corresponding printing task according to the printing data when traversing to the second memory space, the method further includes: when detecting that the communication connection established with any terminal is disconnected, continuing to execute the corresponding printing task according to the printing data.

[0104] Optionally, once the MCU of the printing device 10 generates specific printing component control instructions or line-by-line printing data according to the analysis result of the printing data, no matter how the connection status between the terminal sending the printing data and the printing device 10 is, it will not affect the printing device 10 from executing the corresponding printing task.

[0105] In this embodiment, after the printing device executes the corresponding printing task according to the printing data, even if the terminal sending the printing data is disconnected from it, it will not affect its continued execution of the corresponding printing task, thereby ensuring the continuity and integrity of the execution of the printing task and improving the reliability of data processing and the user experience.

[0106] S310: Feedback status information of the printing task to the terminal according to the connection identifier of the terminal.

[0107] Optionally, the MCU of the printing device 10 continuously monitors the execution progress of the printing task, generates status information of the printing task, and feeds back the status information of the printing task to the corresponding terminal according to the connection identifier associated with the second memory space.

[0108] Among them, the status information of the printing task may include but is not limited to: progress information, error information, time information, resource usage information, etc. The above-mentioned task progress information is used to feedback the completion status of the printing task to the user, which may include but is not limited to: the current number of printed pages, the total number of pages, the number of completed pages, and the task completion ratio, etc. The above-mentioned error information is used to record abnormal conditions during the printing process, which may include but is not limited to: blockage of the printing medium transmission channel, insufficient paper or ink depletion, etc. The above-mentioned time information is used to estimate the completion time of the printing task, which may include but is not limited to the estimated time to print the remaining pages, etc. The above-mentioned resource usage information is used to monitor and record the memory space size occupied by the printing task, CPU usage rate and other resource consumption, which may include but is not limited to: the memory space size occupied by the printing task, CPU usage rate and other resource consumption, etc.

[0109] In this embodiment, the printing device reallocates a second memory space larger than the first memory space for the corresponding terminal based on the start printing instruction data, stores the print data sent by the terminal in the second memory space, and executes the corresponding printing task according to the print data when traversing to the second memory space. According to the connection identifier of the second memory space, the status information of the print task is fed back to the terminal. This not only prevents the print data from overflowing the pre-allocated smaller memory space (the first memory space), thereby improving the reliability of data processing; it also can timely and accurately feed back the status information of the print task to the corresponding terminal, thereby improving the user experience.

[0110] S311: Determine whether the printing task has been completed. If yes, execute S312; if no, execute S309 again.

[0111] Optionally, after executing the corresponding printing task according to the printing data, the MCU of the printing device 10 determines in real time whether the printing data in the second memory space has been parsed and processed. If the printing data has been parsed and processed, it means that the MCU of the printing device 10 has generated specific control instructions for the printing components or line-by-line printing data according to the parsing results, and can continue to traverse the first memory space. If the printing data has not been fully parsed and processed, it means that the MCU of the printing device 10 needs to continue to parse the printing data stored in the second memory space, and generate specific control instructions for the printing components or line-by-line printing data according to the parsing results, and then execute the corresponding printing task according to the control instructions for the printing components or the printing line data.

[0112] S312: Reallocate the first memory space for the terminal.

[0113] Optionally, the completion of the printing task means that the terminal will send a large amount of printing data to the terminal only after issuing the start printing instruction data again. Therefore, a smaller first memory space can be reallocated to the terminal.

[0114] In this embodiment, the MCU of the printing device 10 reallocates the first memory space to the corresponding terminal when the printing task has been completed, which can effectively save its memory resources without affecting the data processing performance of the printing device, thereby improving the data processing speed.

[0115] S313: Continue to traverse the first memory space and execute S304 again.

[0116] Optionally, after determining that the print task corresponding to the second memory space has been completed, the MCU of the printing device 10 continues to traverse the first memory space, and when traversing to any first memory space, determines whether the first memory space stores instruction data to be parsed.

[0117] S314: Execute corresponding instruction tasks according to the instruction data.

[0118] It can be understood that if the instruction data parsed by the MCU of the printing device 10 from the first memory space does not include the start printing instruction data, the MCU directly executes the corresponding instruction task according to the instruction data. Specifically, the MCU takes out the corresponding data from the first memory space for parsing, and records the handle identifier corresponding to the first memory space. After parsing the complete instruction data, the control instruction of the printing component is generated according to the parsed instruction data, and then the corresponding instruction task is executed according to the control instruction of the printing component.

[0119] S315: Feedback the status information of the command task to the terminal according to the connection identifier of the terminal.

[0120] Optionally, after the MCU of the printing device 10 executes the corresponding instruction task according to the instruction data, it feeds back the completion status information of the instruction task to the corresponding terminal according to the connection identifier corresponding to the pre-recorded first memory space (ie, the connection identifier of the terminal).

[0121] In this embodiment, the printing device executes the corresponding instruction task according to the instruction data, and feeds back the status information of the instruction task to any terminal according to the connection identifier corresponding to the pre-recorded first memory space. It can not only accurately feed back information to the corresponding terminal according to the pre-recorded connection identifier, thereby improving the reliability of data processing; it can also improve the user experience by timely feeding back status information to the user.

[0122] S316: Continue traversing the first memory space and execute S304 again.

[0123] Optionally, after determining that the print task corresponding to the second memory space has been completed, the MCU of the printing device 10 continues to traverse the first memory space, and when traversing to any first memory space, determines whether the first memory space stores instruction data to be parsed.

[0124] S317: Continue to traverse the first memory space and execute S304 again.

[0125] Optionally, if the traversed first memory space does not store the instruction data to be parsed, the MCU of the printing device 10 continues to traverse the first memory space, and when traversing to any first memory space, determines whether the first memory space stores the instruction data to be parsed.

[0126] In the above data processing method, when the instruction data includes the start printing instruction data, the printing device reallocates a second memory space larger than the first memory space for the corresponding terminal based on the start printing instruction data, stores the printing data sent by the terminal in the second memory space, and when traversing to the second memory space, executes the corresponding printing task according to the printing data, and feeds back the status information of the printing task to the terminal according to the connection identifier of the second memory space, and reallocates the first memory space for the corresponding terminal when the printing task has been completed. Not only can the printing data be effectively prevented from overflowing the pre-allocated smaller memory space (first memory space), but also the status information of the printing task can be fed back to the corresponding terminal in a timely and accurate manner; in addition, it can also effectively save its memory resources without affecting the data processing performance of the printing device. When the instruction data includes the start printing instruction data, the printing device executes the corresponding instruction task according to the instruction data, and feeds back the status information of the instruction task to any terminal according to the connection identifier corresponding to the pre-recorded first memory space, and can not only accurately feed back the information to the corresponding terminal according to the pre-recorded connection identifier, but also feed back the status information of the instruction task to the user in a timely manner. The above method can improve the reliability of data processing of the printing device, ensure the data processing performance of the printing device, effectively save the memory resources of the printing device, and improve the user experience.

[0127] In one embodiment, Figure 4 As shown, another data processing method is provided, which is applied to Figure 1 The printing device 10 in the embodiment is taken as an example to illustrate, and the following steps are included:

[0128] S401: establishing communication connections with a plurality of terminals respectively, and allocating a first memory space to each terminal after establishing the communication connection with each terminal.

[0129] Specifically, S401 is consistent with S301 and will not be described in detail here.

[0130] S402: receiving instruction data sent by each terminal; each instruction data carries a connection identifier of each terminal.

[0131] Specifically, S402 is consistent with S302 and will not be described in detail here.

[0132] S403: storing each instruction data into a corresponding first memory space according to the connection identifier of each terminal.

[0133] Specifically, S403 is consistent with S303 and will not be described in detail here.

[0134] S404: When traversing to the first memory space corresponding to any terminal, determine whether the first memory space stores instruction data to be parsed. If yes, execute S405; if no, execute S420.

[0135] Specifically, S404 is consistent with S304 and will not be described in detail here.

[0136] S405: parse the instruction data, and record the connection identifier corresponding to the first memory space.

[0137] Specifically, S405 is consistent with S305 and will not be described in detail here.

[0138] S406: Determine whether the instruction data includes the start printing instruction data. If yes, execute S407; if no, execute S417.

[0139] Specifically, S406 is consistent with S306 and will not be described in detail here.

[0140] S407: reallocate the second memory space for the terminal according to the start printing instruction data.

[0141] Specifically, S407 is consistent with S307 and will not be described in detail here.

[0142] S408: storing the print data sent by the terminal into the second memory space.

[0143] Specifically, S408 is consistent with S308 and will not be described in detail here.

[0144] S409: When traversing to any first memory space, determine whether the instruction data stored in the first memory space includes printing instruction data. If yes, execute S410; if no, execute S411.

[0145] It is understandable that if the MCU of the printing device traverses other first memory spaces after reallocating the second memory space for the terminal that sends the start printing instruction data, it is necessary to determine whether the instruction data in the first memory space includes printing instruction data related to printing after parsing the instruction data in the first memory space. If the first memory space contains printing instruction data related to printing, the printing instruction data is rejected to avoid conflicts caused by different printing settings when executing the printing task; if the first memory space does not contain printing instruction data related to printing, the instruction data stored in the first memory space is responded normally.

[0146] The printing instruction data may include but is not limited to: printing task setting instruction data, printing task stop instruction data, etc.; the printing task setting instruction data is used to configure and set various parameters of the printing task, such as paper size, print quality, double-sided printing, etc.

[0147] S410: Reject the response to the printing instruction data.

[0148] It is understandable that if the first memory space contains printing instruction data related to printing, the printing instruction data is rejected to avoid conflicts caused by different printing settings when executing the printing task.

[0149] S411: Respond to the instruction data stored in the first memory space.

[0150] It can be understood that if the first memory space does not contain printing instruction data related to printing, the instruction data stored in the first memory space is responded normally.

[0151] In this embodiment, after the printing device reallocates the second memory space for the terminal that sends the start printing instruction data, if it traverses to any of the first memory spaces, it determines whether the instruction data stored in any of the first memory spaces includes printing instruction data based on the parsed data. If the instruction data stored in the first memory space includes printing instruction data, it refuses to respond to the printing instruction data to avoid conflicts caused by different printing settings when executing the printing task; if the instruction data stored in the first memory space does not include printing instruction data, it responds normally to the instruction data stored in the first memory space, which can effectively improve the stability and reliability of data processing.

[0152] S412: When traversing to the second memory space, executing a corresponding printing task according to the printing data.

[0153] Specifically, S412 is consistent with S309 and will not be repeated here.

[0154] S413: Feedback the status information of the printing task to the corresponding terminal according to the connection identifier of the terminal.

[0155] Specifically, S413 is consistent with S310 and will not be repeated here.

[0156] S414: Determine whether the printing task has been completed. If yes, execute S415; if no, execute S412 again.

[0157] Specifically, S414 is consistent with S311 and will not be repeated here.

[0158] S415: Reallocate the first memory space for the terminal.

[0159] Specifically, S415 is consistent with S312 and will not be repeated here.

[0160] S416: Continue traversing the first memory space and execute S404 again.

[0161] Specifically, S416 is consistent with S313 and will not be repeated here.

[0162] S417: Execute corresponding instruction tasks according to the instruction data.

[0163] Specifically, S417 is consistent with S314 and will not be repeated here.

[0164] S418: Feedback the status information of the command task to the terminal according to the connection identifier of the terminal.

[0165] Specifically, S418 is consistent with S315 and will not be repeated here.

[0166] S419: Continue traversing the first memory space and execute S404 again.

[0167] Specifically, S419 is consistent with S316 and will not be repeated here.

[0168] S420: Continue to traverse the first memory space, and execute S404 again.

[0169] Specifically, S420 is consistent with S317 and will not be repeated here.

[0170] In the above data processing method, after the printing device reallocates the second memory space for the terminal that sends the start printing instruction data, if it traverses to any first memory space, it determines whether the instruction data stored in any first memory space includes printing instruction data based on the parsed data. In the case where the instruction data stored in the first memory space includes printing instruction data, the printing instruction data is refused to be responded to, so as to avoid conflicts caused by different printing settings when executing the printing task; in the case where the instruction data stored in the first memory space does not include printing instruction data, the instruction data stored in the first memory space is responded to normally. The above method improves the stability and reliability of data processing, thereby effectively improving the user experience.

[0171] In one embodiment, Figure 5 As shown, a data processing method is provided, which is applied to Figure 1 The printing device 10 in the embodiment is taken as an example to illustrate, and the following steps are included:

[0172] S501: establishing communication connections with a plurality of terminals respectively, and allocating a first memory space to each terminal after establishing the communication connection with each terminal; each first memory space is associated with a connection identifier of each terminal.

[0173] Specifically, S501 is consistent with S301 and will not be described in detail here.

[0174] S502: When it is detected that the communication connection with any terminal is unstable, a connection status prompt message is sent to any terminal according to a connection identifier of any terminal.

[0175] Optionally, when the MCU of the printing device 10 detects that the communication connection with any terminal is unstable, it sends a connection status prompt message to any terminal according to the connection identifier (such as handle identifier) ​​of any terminal, thereby prompting the user to adjust the network environment in time. Exemplarily, the connection status prompt message may be, but is not limited to, "The current network environment is poor, please adjust the network environment in time."

[0176] In this embodiment, the printing device notifies the user in time when detecting that the communication connection is unstable and sends connection transition prompt information, thereby prompting the user to take necessary measures to improve the network environment and ensure the smooth progress of the printing task.

[0177] S503: In response to a connection disconnection request sent by any terminal, disconnect the communication connection established with any terminal.

[0178] Optionally, after the printing device 10 receives a connection disconnection request sent by any terminal through the wireless communication module, the wireless communication module immediately disconnects the communication connection with the terminal and reports a connection disconnection event including the terminal connection identifier (such as a handle identifier) ​​to the MCU of the printing device 10.

[0179] S504: Clear data in a first memory space corresponding to any terminal according to the connection identifier of any terminal.

[0180] Optionally, after the MCU of the printing device 10 receives a connection disconnection event, it clears the data in the first memory space corresponding to the corresponding terminal according to the connection identifier in the connection disconnection event, thereby immediately releasing the no longer needed memory space so that these resources can be allocated to other terminals, thereby improving resource utilization and memory allocation efficiency.

[0181] In this embodiment, the printing device disconnects the communication connection established with any terminal in response to a connection disconnection request sent by any terminal, and clears the data in the first memory space corresponding to any terminal according to the connection identifier of any terminal, thereby effectively improving resource utilization and memory allocation efficiency.

[0182] In the above data processing method, the printing device can prompt the user to take necessary measures to improve the network environment and ensure the smooth progress of the printing task by notifying the user in time when detecting that the communication connection is unstable and sending a connection transition prompt message; by responding to a connection disconnection request sent by any terminal, disconnecting the communication connection established with any terminal, and clearing the data in the first memory space corresponding to any terminal according to the connection identifier of any terminal, it can effectively improve resource utilization and memory allocation efficiency. The above method can improve the reliability of data processing of the printing device, ensure the data processing performance of the printing device, effectively save the memory resources of the printing device, and enhance the user experience.

[0183] In one embodiment, Figure 6 As shown, a data processing method is provided, which is applied to a printing device and includes the following steps:

[0184] S601: Establish a communication connection with a mother terminal.

[0185] The mother terminal is used to verify the instruction data sent by multiple sub-terminals, and send the verified target instruction data to the printing device. Each target instruction data carries the connection identifier of each sub-terminal. The connection identifier of each sub-terminal can be but is not limited to the handle identifier of each sub-terminal.

[0186] Optionally, the printing device can establish a communication connection with a mother terminal that manages multiple sub-terminals through a communication module. Specifically, each of the multiple sub-terminals can send instruction data carrying its connection identifier to the mother terminal for verification, and the mother terminal sends the multiple instruction data that have passed the verification as multiple target instruction data to the printing device, so that the MCU of the printing device allocates memory space to each sub-terminal according to the connection identifier (such as handle identifier) ​​of each sub-terminal carried by each instruction data.

[0187] S602: receiving a plurality of target instruction data sent by the mother terminal, and after receiving each target instruction data, allocating a first memory space to each child terminal according to a connection identifier carried by each target instruction data.

[0188] The first memory space may be, but is not limited to, a ring buffer in the memory. Each first memory space is associated with a connection identifier of each sub-terminal.

[0189] Optionally, the MCU of the printing device receives multiple target instruction data sent by the mother terminal, and allocates an independent first memory space (such as a ring buffer) to each sub-terminal based on each target instruction data sent by the mother terminal. It can be understood that since the multiple target instruction data initially sent by the mother terminal to the printing device is to confirm the connection status or set printing-related parameters, rather than to transmit a large amount of printing data. Therefore, after the printing device receives the multiple target instruction data sent by the mother terminal, it first allocates a smaller first memory space to each target instruction data according to the connection identifier of each target instruction data, thereby effectively saving its memory resources and improving the data processing speed without affecting the data processing performance of the printing device 10.

[0190] S603: storing each target instruction data into a corresponding first memory space according to the connection identifier of each sub-terminal.

[0191] Optionally, after the MCU of the printing device receives each target command data, it searches for the first memory space of the corresponding terminal in the mapping table maintained internally according to the connection identifier carried by each target command data, and then stores each target command data in the corresponding first memory space found, so that the target command data corresponding to different sub-terminals can be distinguished through partitioned storage management.

[0192] S604: When traversing to the first memory space corresponding to any sub-terminal, execute processing according to the target instruction data corresponding to any sub-terminal.

[0193] Optionally, when the MCU of the printing device 10 traverses to the first memory space corresponding to any sub-terminal, it combines the read / write pointer and the status flag and other mechanisms to determine whether there is instruction data to be parsed in the first memory space. Specifically, the MCU can check the positions of the read pointer and the write pointer of the first memory space (such as the ring buffer). If they are not equal, it means that the instruction data to be parsed is stored in the first memory space; if they are equal, it means that the instruction data to be parsed is not stored in the first memory space. In addition, the MCU will also refer to the status flag to ensure that the same data is not processed repeatedly.

[0194] In the above data processing method, after establishing a communication connection with the mother terminal, the printing device receives multiple target instruction data sent by the mother terminal, and after receiving each target instruction data, allocates a first memory space to each sub-terminal according to the connection identifier carried by each target instruction data, which can ensure that each sub-terminal can have a different independent memory space to save the data sent subsequently; by storing each target instruction data in the corresponding first memory space according to the connection identifier of each sub-terminal, it is helpful to distinguish the instruction data from different terminals through the partition storage management method; by executing the processing according to the target instruction data corresponding to any sub-terminal when traversing to the first memory space corresponding to any sub-terminal, it can correctly process the data from different sub-terminals and provide stable services for users. The above method can simplify the data verification and management process and improve the stability and security of the system by specifying a mother terminal to uniformly manage and confirm the instructions of all sub-terminals; by allocating the first memory space to each sub-terminal according to the connection identifier carried by each target instruction data, it can effectively improve the reliability of data processing of the printing device, ensure the data processing performance of the printing device, effectively save the memory resources of the printing device, and improve the user experience.

[0195] It should be understood that, although the various steps in the flowcharts involved in the above-mentioned embodiments are displayed in sequence according to the indication of the arrows, these steps are not necessarily executed in sequence according to the order indicated by the arrows. Unless there is a clear explanation in this article, the execution of these steps does not have a strict order restriction, and these steps can be executed in other orders. Moreover, at least a part of the steps in the flowcharts involved in the above-mentioned embodiments can include multiple steps or multiple stages, and these steps or stages are not necessarily executed at the same time, but can be executed at different times, and the execution order of these steps or stages is not necessarily to be carried out in sequence, but can be executed in turn or alternately with other steps or at least a part of the steps or stages in other steps.
