Description

Technical Field

[0001] The present disclosure relates to the field of computer technology, and in particular to a signal processing method, apparatus, device, and computer-readable storage medium. Background Art

[0002] Receiving a signal is an uncertain emergency. The signal processing mechanism of the existing operating system is: when a thread receives a signal, the operating system will wait until the scheduling point of the thread, then suspend the execution of the thread's program, save the thread's context, and execute the signal processing function of the signal. When the signal processing function of the signal is completed, the operating system will restore the context saved before the thread was suspended, and execute the program that was originally suspended by the thread again.

[0003] In some scenarios: 1) The target thread is currently executing an urgent task and has received many signals, but these signals are not urgent. According to the existing signal processing mechanism, when the scheduling point of the target thread arrives, the execution of the thread will be suspended, and the previously suspended thread will be executed after all signal processing functions are executed, which will affect the certainty and reliability of the thread task execution time; 2) The target thread is currently executing a non-urgent task. At this time, if an urgent signal is sent to the target thread, the target thread needs to wait until the scheduling point and return to the user space to execute the signal processing function, which will affect the real-time response to the emergency signal.

[0004] Therefore, the existing signal processing mechanism will affect the reliability, determinism and real-time performance of the real-time operating system. Summary of the invention

[0057] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0058] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0059] The embodiment of the present disclosure provides a signal processing method, which is introduced below in conjunction with a specific embodiment.

[0060] Figure 1 The flowchart of the signal processing method provided by the embodiment of the present disclosure. The method can be applied to electronic devices, which can be portable mobile devices such as smart phones, tablet computers, laptops, car navigation devices, smart sports equipment, etc.; they can also be fixed devices such as personal computers and smart home appliances. The method can be applied to the scene of signal processing. The method solves the problem that the signal processing mechanism in the prior art will affect the reliability, determinism and real-time performance of the real-time operating system. When the target signal is received, the priority of the target signal is obtained, a signal response thread is set for the target signal, and the priority of the signal response thread is set according to the priority of the target signal; wherein, the higher the priority of the target signal, the higher the priority of the corresponding signal response thread, the signal is threaded, each signal has a signal response thread with a priority, the signal response thread is added to the corresponding signal response thread group, and the threads to be processed in the signal response thread group are processed in order from high to low priority, which can avoid non-emergency signals affecting the processing of emergency tasks, and can ensure the real-time performance of emergency signal response, thereby ensuring the reliability, determinism and real-time performance of the real-time operating system. It can be understood that the signal processing method provided by the embodiment of the present disclosure can also be applied in other scenarios, which are not limited here.

[0061] Below Figure 1 The signal processing method shown in the figure is introduced, and the specific steps of the method are as follows:

[0062] S101. When a target signal is received, obtain the priority of the target signal.

[0063] In this step, when a target signal is received, the electronic device can obtain the priority of the target signal. The number of target signals received by the electronic device can be one or more; the priority of the target signal can be the urgency carried by the signal transmitter when sending the signal. After receiving the target signal, the electronic device determines its corresponding priority according to the urgency carried by the target signal and the pre-saved correspondence between the urgency and the priority; it can also be the priority directly carried by the target signal sent by the signal transmitter. In some embodiments, the priority of the target signal can also be set by the user. In response to the user's setting operation, the corresponding priority is configured for the target signal, wherein the setting operation carries the priority to be configured.

[0064] In some embodiments, when an electronic device receives a target signal, the electronic device will register the target signal and configure the priority of the target signal to save the priority of the target signal as the attribute information of the target signal. When registering a signal, the electronic device will also configure other relevant information of the target signal (for example, signal type, sender, destination process, etc.). Optionally, the sender of the signal carries the urgency of the signal when sending the signal. When configuring the priority of the target signal according to the urgency, for an urgent signal, the priority of the signal is configured to be higher, and for a non-urgent signal, the priority of the signal is configured to be lower.

[0065] In some embodiments, the target signal carries at least one of the following attribute information: a type identifier of the target signal, an identifier of a target sending end of the target signal, and an identifier of a target destination thread of the target signal.

[0066] The attribute information of the signal may be any one or a combination of the type identifier of the target signal, the identifier of the target sending end of the target signal, the target destination end thread identifier of the target signal, or other information, which is not limited in this embodiment.

[0067] The target destination thread is the thread on which the signal acts; the sender of the signal refers to the application or device that sends the signal; the types of signals include start, exit, etc., and each type corresponds to a type identifier.

[0068] S102, setting a signal response thread for the target signal, and setting the priority of the signal response thread according to the priority of the target signal; wherein, the higher the priority of the target signal is, the higher the priority of the corresponding signal response thread is.

[0069] In order to reduce the workload of the electronic device, the electronic device creates a signal response thread for each type of signal and sets the priority of the signal response thread according to the priority of the signal. The higher the priority of the target signal, the higher the priority of the corresponding signal response thread.

[0070] In some embodiments, the S102 sets a signal response thread for the target signal, including but not limited to S1021, S1022, and S1023:

[0071] S1021, determining whether a signal response thread corresponding to the type identifier of the target signal already exists;

[0072] In this embodiment, the electronic device determines whether a signal response thread corresponding to the type identifier of the target signal already exists, and if not, executes S1022; if so, executes S1023.

[0073] S1022: If not, setting a signal response thread for the target signal;

[0074] When there is no signal response thread corresponding to the type identifier of the target signal in the electronic device, a signal response thread is set for the target signal.

[0075] S1023: If yes, determine the signal response thread corresponding to the type identifier of the target signal as the signal response thread of the target signal.

[0076] When a signal response thread corresponding to the type identifier of the target signal already exists in the electronic device, the signal response thread is not created, and the signal response thread corresponding to the type identifier of the target signal is determined as the signal response thread of the target signal. Since signals of the same signal type correspond to the same signal response thread, if a signal response thread of this type already exists, it does not need to be created, thereby avoiding repeated creation of signal response threads and causing signal response thread redundancy.

[0077] S103, adding the signal response thread to the corresponding signal response thread group. For any signal response thread group, processing the threads to be processed in the signal response thread group in order of priority from high to low, so as to execute the signal response thread in the signal response thread group so that the target signal is processed.

[0078] After creating the signal response thread, the electronic device further adds the signal response thread to the corresponding signal response thread group, wherein the signal response thread group includes one or more signal response threads and a target destination thread, and the signal response thread group is equivalent to a container or queue for storing threads to be processed. For any signal response thread group, the threads to be processed in the signal response thread group are processed in order of priority from high to low, so as to execute the signal response thread in the signal response thread group so that the target signal is processed. Specifically, according to the priority of the signal response thread and the target destination thread in the signal response thread group, each thread is processed in order from high to low priority, thereby realizing the processing of the target signal.

[0079] The embodiment of the present disclosure obtains the priority of the target signal when a target signal is received, sets a signal response thread for the target signal, and sets the priority of the signal response thread according to the priority of the target signal; wherein, the higher the priority of the target signal, the higher the priority of the corresponding signal response thread, and the signal response thread is added to the corresponding signal response thread group. For any signal response thread group, the threads to be processed in the signal response thread group are processed in descending order of priority to execute the signal response thread in the signal response thread group so that the target signal is processed. The present invention solves the problem that the signal processing mechanism in the prior art may affect the reliability, determinism and real-time performance of a real-time operating system. When a target signal is received, the priority of the target signal is obtained, a signal response thread is set for the target signal, and the priority of the signal response thread is set according to the priority of the target signal; wherein, the higher the priority of the target signal, the higher the priority of the corresponding signal response thread; the signal is threadedly processed, each signal has a signal response thread with a priority, the signal response thread is added to the corresponding signal response thread group, and the threads to be processed in the signal response thread group are processed in sequence from high to low priority, that is, each time a thread receives a new signal, it does not need to wait for the scheduling point of the thread, suspend the execution of the program of the thread, and resume the original program of the thread after the signal processing function of the new signal is executed, but waits for other signals with a higher priority than the new signal to be processed, and then directly processes the signal, thereby saving the signal processing flow, and avoiding the non-urgent signal from affecting the processing of the urgent task, and ensuring the real-time performance of the urgent signal response, thereby ensuring the reliability, determinism and real-time performance of the real-time operating system.

[0080] Figure 2 A flow chart of a signal processing method provided by another embodiment of the present disclosure is as follows: Figure 2 As shown, the method includes the following steps:

[0081] S201. When a target signal is received, obtain the priority of the target signal.

[0082] Specifically, the implementation process and principle of S201 and S101 are the same, and will not be repeated here.

[0083] S202: Determine whether the target signal is a signal that is allowed to be responded to, based on whether the attribute information of the target signal meets a preset attribute information condition.

[0084] After obtaining the attribute information of the signal, the electronic device determines whether the target signal is a signal that is allowed to be responded to according to whether the attribute information of the target signal satisfies the preset attribute information condition. Specifically, if the attribute information of the target signal satisfies the preset attribute information condition, the target signal is determined to be a signal that is allowed to be responded to; otherwise, the target signal is determined not to be a signal that is allowed to be responded to.

[0085] In some embodiments, S202 may include but is not limited to S2021, S2022, S2023, S2024:

[0086] S2021, judging whether the target sending end of the target signal has sending authority according to the identifier of the target sending end of the target signal and the identifier of the sending end with sending authority that is stored in advance;

[0087] In the electronic device, sending permissions are opened for some senders, while other senders do not have sending permissions. Signals sent by senders without sending permissions will not be allowed to be processed. Based on the identifier of the target sender of the target signal and the identifier of the sender with sending permissions that is pre-saved, it is determined whether the target sender of the target signal has sending permissions.

[0088] S2022, determining whether the type identifier of the target signal is the same as the type identifier of the signal currently being processed;

[0089] The electronic device determines whether the type identifier of the target signal is the same as the type identifier of the signal currently being processed, and if they are the same, the signal will be blocked (suspended).

[0090] S2023: judging whether the type of the target signal is an ignored signal type according to the type identifier of the target signal and the pre-stored type identifier of the ignored signal;

[0091] The electronic device is provided with a type number of the ignored signal, and can judge whether the type of the target signal is the ignored signal type according to the type identifier of the target signal and the type identifier of the ignored signal stored in advance.

[0092] Among them, the execution order of S2021, S2022 and S2023 can be executed simultaneously or not at the same time. When they are not executed simultaneously, the execution order of S2021, S2022 and S2023 can be set arbitrarily, which will not be elaborated here.

[0093] S2024. If the target sending end of the target signal has the sending permission, the type identifier of the target signal is different from the type identifier of the signal currently being processed, and the type of the target signal is not an ignored signal type, then the target signal is a signal that is allowed to be responded to.

[0094] If the target sender of the target signal has the sending permission, the type identifier of the target signal is different from the type identifier of the signal currently being processed, and the type of the target signal is not an ignored signal type, the electronic device determines that the target signal is a signal that is allowed to be responded to; otherwise, the electronic device determines that the target signal is not a signal that is allowed to be responded to.

[0095] S203. If the signal is a signal that is allowed to be responded to, a signal response thread is set for the target signal, and the priority of the signal response thread is set according to the priority of the target signal; wherein, the higher the priority of the target signal, the higher the priority of the corresponding signal response thread.

[0096] When the signal is a signal that is allowed to be responded to, the electronic device sets a signal response thread for the target signal and sets the priority of the signal response thread according to the priority of the target signal; wherein, the higher the priority of the target signal, the higher the priority of the corresponding signal response thread.

[0097] In some embodiments, the electronic device will create a signal response thread group for each target destination thread in advance, and add the target destination thread to the signal response thread group. The thread on which the signal acts is called the target destination thread. In other words, the signal response thread group includes the target destination thread.

[0098] S204: Find out the signal response thread group where the target destination thread is located according to the target destination thread identifier of the target signal, and add the signal response thread to the signal response thread group where the target destination thread is located.

[0099] The electronic device finds the signal response thread group where the target destination thread is located according to the target destination thread identifier of the target signal, and adds the signal response thread to the signal response thread group where the target destination thread is located. At this time, the signal response thread group includes the target destination thread and the signal response thread.

[0100] S205: Process the threads to be processed in the signal response thread group in order of priority from high to low.

[0101] In this step, the electronic device processes the threads to be processed in the signal response thread group in descending order of priority. Specifically, the electronic device processes each thread in descending order of priority according to the priority of the signal response thread and the target destination thread in the signal response thread group.

[0102] The embodiment of the present disclosure obtains the priority of the target signal when a target signal is received, and determines whether the target signal is a signal that is allowed to be responded to based on whether the attribute information of the target signal meets the preset attribute information conditions. If the signal is a signal that is allowed to be responded to, a signal response thread is set for the target signal, and the priority of the signal response thread is set according to the priority of the target signal; wherein, the higher the priority of the target signal, the higher the priority of the corresponding signal response thread. Further, a target destination thread is created for the destination identifier, the target destination thread is added to the signal response thread group, the signal response thread group where the target destination thread is located is found according to the target destination thread identifier of the target signal, and the signal response thread is added to the signal response thread group where the target destination thread is located. Then, the threads to be processed in the signal response thread group are processed in order of priority from high to low. Compared with the prior art, since the target signal is first judged whether it is a signal that is allowed to be responded to based on whether the attribute information of the target signal meets the preset attribute information conditions, the security of the real-time operating system can be improved. Furthermore, the signal response thread group where the target destination thread is located is found according to the target destination thread identifier of the target signal, and the signal response thread is added to the signal response thread group where the target destination thread is located. Then, according to the priority of the signal response thread and the target destination thread in the signal response thread group, each thread is processed in sequence from high to low priority, which can avoid non-urgent signals affecting the processing of urgent tasks, and can ensure the real-time response of urgent signals, thereby ensuring the reliability, determinism and real-time performance of the real-time operating system.

[0103] Figure 3 A flow chart of a signal processing method provided by another embodiment of the present disclosure is as follows: Figure 3 As shown, the method includes the following steps:

[0104] S301. When a target signal is received, obtain the priority of the target signal.

[0105] Specifically, the implementation process and principle of S301 and S101 are the same, and will not be repeated here.

[0106] S302, setting a signal response thread for the target signal, and setting the priority of the signal response thread according to the priority of the target signal; wherein, the higher the priority of the target signal is, the higher the priority of the corresponding signal response thread is.

[0107] Specifically, the implementation process and principle of S302 and S102 are the same, and will not be repeated here.

[0108] S303: Find out the signal response thread group where the target destination thread is located according to the target destination thread identifier of the target signal, and add the signal response thread to the signal response thread group where the target destination thread is located.

[0109] Specifically, the implementation process and principle of S303 and S204 are the same, and will not be repeated here.

[0110] S304: Compare the priorities of the signal response threads in the signal response thread group and the target destination thread, and determine the thread corresponding to the highest priority as the target thread.

[0111] After adding the signal response thread to the signal response thread group where the target destination thread is located, the electronic device compares the priorities of the signal response threads in the signal response thread group and the target destination thread, and determines the thread corresponding to the highest priority as the target thread.

[0112] S305: Process the target thread.

[0113] After determining the target thread, the electronic device processes the target thread.

[0114] In some embodiments, S305 may include but is not limited to S3051, S3052, S3053:

[0115] S3051, when the target thread is the signal response thread, running a signal processing function to process the signal response thread;

[0116] In this step, when the target thread is the signal response thread, that is, when the signal response thread has the highest priority, the electronic device runs the signal processing function to process the signal response thread, thereby ensuring the real-time performance of the emergency signal response.

[0117] S3052, determining whether there is a signal with the same type identifier as the target signal in the currently received signal;

[0118] Since each type of signal creates a signal response thread, the essence of this step is to determine whether there is a signal of the same type as the currently received signal that is blocked (suspended).

[0119] S3053: If so, call the signal processing function to process the signal with the same type identifier as the target signal in the currently received signal.

[0120] If so, the electronic device calls the signal processing function to process the signal with the same type identifier as the target signal in the currently received signal until there is no signal with the same type identifier as the target signal in the currently received signal.

[0121] In some embodiments, the processing the target thread includes: when the target thread is a target destination thread, processing the target destination thread in a preset manner.

[0122] When the target thread is the target destination thread, that is, the target destination thread has the highest priority, the target destination thread is processed in a preset manner. The target destination thread is a common thread, and the processing of the target destination thread can be realized by running the corresponding instructions. Specifically, the electronic device processes the tasks in the target destination thread, which can prevent non-urgent signals from affecting the processing of urgent tasks.

[0123] The process of processing the target destination thread in a preset manner is a prior art and will not be described in detail here.

[0124] S306 , when the target thread is processed, the thread with the highest priority among the remaining threads in the signal response thread group is determined as the target thread, and the processing continues until all threads in the signal response thread group are processed.

[0125] After the target thread is processed, the electronic device determines the thread with the highest priority among the remaining threads in the signal response thread group as the target thread, and continues processing until all threads in the signal response thread group are processed.

[0126] When a target signal is received in the embodiment of the present disclosure, the priority of the target signal is obtained, a signal response thread is set for the target signal, and the priority of the signal response thread is set according to the priority of the target signal; wherein, the higher the priority of the target signal, the higher the priority of the corresponding signal response thread. Further, the signal response thread group where the target destination thread is located is found according to the target destination thread identifier of the target signal, the signal response thread is added to the signal response thread group where the target destination thread is located, the priorities of the signal response threads and the target destination threads in the signal response thread group are compared, the thread corresponding to the highest priority is determined as the target thread, and the target thread is processed. Then, when the target thread is processed, the thread with the highest priority among the remaining threads in the signal response thread group is determined as the target thread, and the processing continues until all threads in the signal response thread group are processed. Compared with the prior art, since the priorities of the signal response thread and the target destination thread in the signal response thread group are compared, the thread corresponding to the highest priority is determined as the target thread, and the target thread is processed. After the target thread is processed, the thread with the highest priority among the remaining threads in the signal response thread group is determined as the target thread, and the processing is continued until all threads in the signal response thread group are processed. This can avoid non-emergency signals affecting the processing of emergency tasks, and can ensure the real-time performance of emergency signal response, thereby ensuring the reliability, determinism and real-time performance of the real-time operating system.
