[0056] 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.

[0057] The present application embodiment provides a data processing method, which can be applied to Figure 1 In the application environment shown. The application environment includes a terminal device and a wireless communication module, wherein the terminal device may be, but is not limited to, various smart phones, tablet computers, IoT devices, vehicle-mounted devices and portable wearable devices, and the IoT devices may be smart speakers, smart TVs, smart air conditioners, smart vehicle-mounted devices, projection devices, etc. Portable wearable devices may be smart watches, smart bracelets, head-mounted devices, etc. Head-mounted devices may be virtual reality (VR) devices, augmented reality (AR) devices, smart glasses, etc. The terminal device may have communication functions, such as SMS functions, voice functions, etc. The wireless communication module may be a low-orbit satellite communication module. The terminal device and the wireless communication module may be connected via a physical cable. A control process and multiple application processes may be running in the terminal device, and the application process and the control process may be connected to their corresponding virtual serial ports respectively, and transparently communicate with the corresponding processes in the wireless communication module.

[0058] The data transmission method provided by this application will be described in detail below in conjunction with specific implementation methods. Figure 2 As shown, the method can be applied to a terminal device, comprising the following steps:

[0059] Step 202: Monitor readable events on multiple serial ports through a preset event monitoring mechanism.

[0060] The multiple serial ports include at least one physical serial port and a virtual serial port corresponding to the physical serial port.

[0061] In an embodiment of the present application, after the terminal device is started, the corresponding physical serial port can be initialized through the serial port multiplexing process according to the serial port specification of the wireless communication module, and the file descriptor of the physical serial port can be obtained. Multiple virtual serial ports can also be created through the serial port multiplexing process, and the virtual serial port file descriptor can be obtained. Among them, one virtual serial port among the multiple virtual serial ports can be used to carry channel control commands, and other virtual serial ports can be used to carry logical channel data. In an example, a virtual serial port can be created by using openpty system calls and com0com drivers. The terminal device can also register a signal capture function. The signal capture function can be used to release all resources and exit the process when a termination signal is received. The signal capture function can use SIGINT, SIGTERM, SIGKILL, etc., or a custom signal can be used.

[0062] The terminal device can also initialize the wireless communication module through the serial port multiplexing process, and enter the multiplexed transmission mode by sending AT commands. In addition, according to the preset protocol, it can send control commands to the virtual serial port of the corresponding control channel to open the required logical channel. Then, the terminal device can monitor readable events on multiple serial ports through a preset event monitoring mechanism. Among them, the event monitoring mechanism can optionally adopt event-driven mechanisms provided by operating systems such as epoll, select, kqueue, IOCP (I / O Completion Port, I / O Completion Port). It can be understood that this solution can be executed by the serial port multiplexing process in the terminal device.

[0063] Step 204 , when a readable event of a target serial port among the multiple serial ports is detected, read the target data corresponding to the target serial port.

[0064] In an embodiment of the present application, when a terminal device needs to send data, an application process in the terminal device can perform data transmission through a virtual serial port, and the terminal device can monitor the virtual serial port to determine whether there is data to be sent, so as to send the data to the wireless communication module through the physical serial port for data transmission. When the wireless communication module receives the data sent to the terminal device, the wireless communication module can send the data to the physical serial port of the terminal device through the local physical serial port so that the terminal device can receive the data. Therefore, based on the above situation, the terminal device can monitor the readable event of the target serial port (i.e., the physical serial port and / or the virtual serial port), and can obtain the target data corresponding to the target serial port. It can be understood that both of the above scenarios exist in actual applications, and the terminal device can process the corresponding target data in sequence according to the monitoring time sequence of the readable event. If the readable events of the physical serial port and the virtual serial port occur at the same time, the terminal device can process the target data of the high-priority serial port according to the preset serial port priority, and then process the target data of the low-priority serial port. In one example, the priority of the physical serial port can be higher than the priority of the virtual serial port.

[0065] Step 206: Process the target data based on the processing strategy corresponding to the target serial port.

[0066] In the embodiment of the present application, different types of serial ports have different processing strategies. The terminal can determine the processing strategy corresponding to the type of the target serial port according to the type of the target serial port, and then process the target data based on the processing strategy. For example, when the target serial port is a physical serial port, the terminal device can forward the target data to the corresponding virtual serial port to transmit the target data to the corresponding application for processing through the virtual serial port; when the target serial port is a virtual serial port, the terminal device can forward the target data to the physical serial port to send the target data for processing through the physical serial port.

[0067] In this solution, the serial port multiplexing protocol can be implemented through the event monitoring mechanism, without relying on a specific kernel driver, and without adapting and adjusting business functions for different kernel versions, thereby improving the stability of business functions. At the same time, since there is no need to rely on a specific kernel driver, this solution can implement the serial port multiplexing protocol on different operating system platforms, thereby improving portability. In addition, this embodiment uses an independent serial port multiplexing process to manage the communication with the actual physical serial port, and the application process only needs to focus on the data transmission and reception of the logical channel, thereby realizing the separation of business logic and serial port multiplexing logic. Moreover, this embodiment implements event monitoring based on an event-driven mechanism, thereby avoiding the problems of large memory usage and frequent system calls in the multi-process / multi-thread monitoring method, and effectively saving the processing resources of the device.

[0068] Optionally, the method further includes: adding the file descriptor of the physical serial port and the file descriptor of the virtual serial port to a preset monitoring queue.

[0069] In the embodiment of the present application, when initializing the physical serial port and the virtual serial port, the terminal device can obtain the file descriptor of the physical serial port and the file descriptor of the virtual serial port. Then, the file descriptor of the physical serial port and the file descriptor of the virtual serial port can be added to the preset listening queue. The listening port in the terminal device can read the file descriptor from the listening queue, and then monitor the corresponding serial port based on the file descriptor, thereby monitoring the readable events of the serial port, and can wait for the event to occur in a loop.

[0070] In this solution, event monitoring can be implemented based on an event-driven mechanism, avoiding the problems of large memory usage and frequent system calls in multi-process / multi-thread monitoring methods, and effectively saving device processing resources.

[0071] Optionally, the target data is processed based on the processing strategy corresponding to the target serial port, including: when the target serial port is a physical serial port, the target data is stored in a preset buffer, and it is determined whether the data in the buffer meets the data verification condition; if the data in the buffer meets the data verification condition, the data in the buffer is forwarded to the virtual serial port; if the data in the buffer does not meet the data verification condition, the data in the buffer is discarded.

[0072] In the embodiment of the present application, after the terminal device is started, a buffer can also be initialized. The buffer can adopt a data structure such as a ring buffer, a linked list buffer, a queue buffer, etc. The buffer can be used to cache the received data. The buffer can be a first-in-first-out queue, which supports the binary data received by the physical serial port to be queued in sequence by byte, and can be dequeued by byte.

[0073] In the case where the target serial port is a physical serial port, the terminal device can read the target data received by the physical serial port, then store the target data in a preset buffer, and determine whether the amount of data in the buffer is greater than or equal to the preset data amount threshold. If the amount of data in the buffer is greater than or equal to the preset data amount threshold, determine whether the data in the buffer meets the data verification condition. If the data in the buffer meets the data verification condition, the data in the buffer is forwarded to the virtual serial port; if the data in the buffer does not meet the data verification condition, the data in the buffer is discarded. If the amount of data in the buffer is less than the preset data amount threshold, no processing is performed until the amount of data in the buffer is greater than or equal to the preset data amount threshold.

[0074] In this solution, the data can be verified and the verified data can be forwarded to the virtual serial port, which can ensure the correctness of the data and improve the reliability of data transmission.

[0075] Optionally, determining whether the data in the buffer satisfies a data verification condition includes: when the amount of data in the buffer is greater than or equal to a preset data amount threshold, parsing the data in the buffer and verifying the parsed data; if the data in the buffer is parsed successfully and verified successfully, the data verification condition is met; if the data in the buffer fails to be parsed or verified, the data verification condition is not met.

[0076] In an embodiment of the present application, when the amount of data in the buffer is greater than or equal to a preset data amount threshold, the terminal device can call the frame structure definition of a preset protocol (such as the GSM0710 protocol) to parse the buffer data. For example, data parsing can be performed using parsing methods such as finite state machines, regular expressions, and recursive descent. Then, the terminal device can verify the parsed data based on pre-configured verification rules. For example, the data can be checked for integrity or consistency, such as using a CRC8 checksum algorithm to calculate the checksum of the data header and compare it with the FCS field of the frame message. If the data in the buffer is parsed successfully and the verification is successful, the data verification condition is met; if the data in the buffer fails to be parsed or the verification fails, the data verification condition is not met. Then, the terminal device can loop event monitoring and continue to wait for a readable event to occur.

[0077] In this solution, in high-throughput scenarios, data caching and verification mechanisms can be implemented to determine whether the data is erroneous, tampered with, or complete, thereby ensuring data reliability and consistency.

[0078] Optionally, based on the processing strategy corresponding to the target serial port, the target data is processed, including: when the target serial port is a virtual serial port, the target data is packaged to obtain data to be transmitted; and the data to be transmitted is forwarded to the physical serial port.

[0079] In the embodiment of the present application, when the target serial port is a virtual serial port, the terminal device can package the target data according to the frame structure in the preset protocol (such as the GSM0710 protocol) to obtain the data to be transmitted, and then forward the packaged data to be transmitted to the physical serial port. Then, the terminal device can loop the event monitoring and continue to wait for the readable event to occur.

[0080] In this solution, by monitoring the readable events of the virtual serial port, the target data of the virtual serial port is packaged and processed to obtain the data to be transmitted, and then the data to be transmitted is forwarded to the physical serial port. The serial port multiplexing protocol can be implemented through the event monitoring mechanism, without relying on a specific kernel driver, and without adapting and adjusting business functions for different kernel versions, which improves the stability of business functions.

[0081] Optionally, the method further includes: in response to the termination signal, sending a close command through the control channel, the close command being used to close the logical channel; and releasing resources of the virtual serial port and resources of an associated process corresponding to the virtual serial port.

[0082] In the embodiment of the present application, after receiving the termination signal, the terminal device can exit the event monitoring loop. Then, the wireless communication module can be enabled through the serial port multiplexing process, and a close command can be sent through the control channel. The close command is a control command for closing other logical channels, thereby enabling the virtual serial port and the physical serial port, releasing the resources of the virtual serial port and the resources of the associated process corresponding to the virtual serial port.

[0083] In this solution, resources can be released after receiving the termination signal, thus avoiding system resource occupation and providing high resource utilization.

[0084] The present invention provides an example of a data processing method, which can be applied to Figure 3 In the system framework shown, the system framework includes an application process, a virtual serial port, a serial port multiplexing process and a physical serial port, and the physical serial port is connected to the wireless communication module through a cable. The method can be implemented by a serial port multiplexing process, and the serial port multiplexing process can manage more than one physical serial port device and corresponding multiple logical channels. Figure 4 As shown, the following steps are included:

[0085] Step 401, initialize the physical serial port, create a virtual serial port, and initialize the buffer.

[0086] Step 402, registering a signal capture function.

[0087] Step 403, initialize the wireless communication module, send an AT command on the physical channel, enable serial port multiplexing, and send a command to enable a logical channel on the control channel.

[0088] Step 404: monitor readable events on the physical serial port and the virtual serial port through a preset event monitoring mechanism.

[0089] Step 405, determining whether a termination signal is received.

[0090] If yes, execute step 413; otherwise, execute step 406.

[0091] Step 406, monitoring whether a readable event occurs.

[0092] If yes, when the target serial port is a physical serial port, execute step 407 ; when the target serial port is a virtual serial port, execute step 411 ; otherwise, execute step 404 .

[0093] Step 407: Store the target data corresponding to the physical serial port into a preset buffer.

[0094] Step 408, determining whether the amount of data in the buffer is greater than or equal to a preset data amount threshold.

[0095] If yes, execute step 409; otherwise, execute step 404.

[0096] Step 409, determine the parsing result of the data in the buffer and judge whether the verification passes.

[0097] If the data in the buffer is parsed successfully and verified, step 410 is executed; otherwise, the data in the buffer is discarded and step 404 is executed.

[0098] Step 410: forward the data in the buffer to the virtual serial port according to the analysis result.

[0099] Step 411, according to the current channel sequence number, the target data is packaged to obtain data to be transmitted.

[0100] Step 412: forward the data to be transmitted to the physical serial port.

[0101] Step 413, enabling the wireless communication module, and sending a close command on the control channel; the close command is used to close the logical channel.

[0102] Step 414 , enabling and removing the virtual serial port, releasing the resources of the virtual serial port and the resources of the associated process corresponding to the virtual serial port.
