The real-time performance of embedded operating systems is reflected in completing the specified tasks within a limited time and responding to external asynchronous events.
[0003] When designing embedded operating system software, it is necessary to perform logging tasks through the embedded operating system to record the generated error data or key status data. This process requires frequent IO (Input / Output) operations on the embedded operating system. At the same time, the embedded operating system will also perform other tasks with high real-time requirements, and will also perform frequent IO operations, which will occupy a large amount of CPU resources of the embedded device, making the CPU overloaded and affecting the real-time performance of the embedded operating system. In the prior art, the error data or key status data of the embedded operating system is sent to the backup device through UDP (User Datagram Protocol) for recording, which will not affect the real-time performance of the embedded operating system of the embedded device, but this requires the addition of an additional device that does not require real-time performance, consumes network resources, increases the complexity of the solution, and has a high implementation cost.

[0052] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution of the present application will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.
[0053] To facilitate understanding of this embodiment, the embodiments of the present application are described in detail below.
[0054] The present application embodiment provides a log recording method, such as Figure 1 As shown, Figure 1 A flow chart of a log recording method provided in an embodiment of the present application. The embedded operating system includes an arbitration module 21 and a data processing module 22, and the method includes the following steps:
[0055] S101, the arbitration module 21 obtains the associated information of the target task being executed by the embedded operating system.
[0056] The target tasks include: real-time tasks and non-real-time tasks, and the priority of the non-real-time tasks is lower than that of the real-time tasks.
[0057] Specifically, after obtaining the associated information, the arbitration module 21 may further determine the real-time requirement of the target task for the embedded operating system according to the associated information of the target task.
[0058] S102, the arbitration module 21 determines whether the target task is a non-real-time task according to the description of the target task in the associated information, and if so, executes step S103, and if not, executes step S106.
[0059] Specifically, the above description is a priority. The arbitration module 21 determines whether the target task is a non-real-time task according to the priority of the associated information. For example, the target tasks to be executed include a, b, and c. The priority of a is preset to be higher than the priority of b, and the priority of b is higher than the priority of c. The target task with a priority lower than or equal to the priority of b is a non-real-time task.
[0060] S103, the arbitration module 21 determines whether the real-time task stops running, if so, executes step S104, if not, executes step S106.
[0061] Specifically, the priority of the real-time task is higher than that of the non-real-time task. The arbitration module 21 determines whether the real-time task stops running to determine whether to send the first instruction or the second instruction to the data processing module 22 .
[0062] S104 , the arbitration module 21 sends a first instruction to the data processing module 22 .
[0063] Specifically, if the target task is a non-real-time task, the data processing module 22 sends a first instruction to the data processing module 22 through the semGive function, wherein the semGive function is a semaphore release function. From the above, it can be seen that if the target task currently executed by the embedded operating system is b (non-real-time task) or c (non-real-time task), the arbitration module 21 sends a first instruction to the data processing module 22.
[0064] S105: the data processing module 22 records the execution log of the target task according to the first instruction.
[0065] Specifically, the first instruction is a semaphore. The semaphore is used to control access to shared resources and realize synchronization and mutual exclusion between processes or threads. The data processing module 22 obtains the semaphore, which means that the target task currently executed by the embedded operating system is a non-real-time task. The target task has low requirements for the real-time performance of the embedded operating system. At this time, the IO interface of the embedded operating system is not busy and the CPU burden is light. At this time, the data processing module 22 records the execution log of the target task, which will not affect the real-time performance of the embedded operating system.
[0066] S106 , the arbitration module 21 sends a second instruction to the data processing module 22 .
[0067] Specifically, if the target task is a real-time task, the arbitration module 21 sends the second instruction to the data processing module 22. As can be seen from the above, if the target task currently executed by the embedded operating system is a (real-time task), the arbitration module 21 sends the second instruction to the data processing module 22.
[0068] S107, the data processing module 22 records the execution log of the target task after a delay of the first period according to the second instruction.
[0069] Specifically, the data processing module 22 obtains the second instruction, which means that the target task executed by the current embedded operating system is a real-time task. The target task has high requirements on the real-time performance of the embedded operating system. At this time, the IO interface of the embedded operating system is relatively busy and the CPU is heavily burdened. At this time, the data processing module 22 records the execution log of the target task, which will affect the real-time performance of the embedded operating system. Therefore, after obtaining the second instruction, the data processing module 22 delays the first period, waits for the target task to be executed, and then records the execution log of the target task.
[0070] The embodiment of the present application provides a log recording method, in which the arbitration module 21 determines whether the target task is a non-real-time task according to the description of the target task in the associated information. If so, the arbitration module 21 sends a first instruction to the data processing module 22, so that the data processing module 22 records the execution log of the target task according to the first instruction; if not, the arbitration module 21 sends a second instruction to the data processing module 22, so that the data processing module 22 records the execution log of the target task after delaying the first period according to the second instruction. In the prior art, regardless of whether the target task currently executed by the embedded operating system is a non-real-time task, the data processing module 22 will record the execution log of the target task. Compared with the prior art, the method adds an arbitration module 21, and the data processing module 22 records the execution log of the target task when it obtains the first instruction sent by the arbitration module 21. After the data processing module 22 obtains the first instruction sent by the arbitration module 21, it delays and waits for the first period to record the execution log of the target task.
[0071] The method does not require frequent IO operations, relieves the CPU burden, occupies less CPU resources, and ensures the real-time performance of the embedded operating system when executing the target task. In addition, the method does not require additional logging equipment outside the embedded operating device, saves network resources, reduces the complexity of the solution, and reduces the implementation cost.
[0072] In one implementation, if the target task is a real-time task, the arbitration module 21 sends a first instruction to the data processing module 22 after a delay of a first period of time, so that the data processing module 22 records the execution log of the target task according to the first instruction.
[0073] Specifically, in the above method, the target task currently executed by the embedded operating system is a real-time task, which has high requirements on the real-time performance of the embedded operating system. At this time, the IO interface of the embedded operating system is relatively busy and the CPU is heavily burdened. If the data processing module 22 records the execution log of the target task at this time, it will affect the real-time performance of the embedded operating system. Therefore, the arbitration processing module will delay the first time period, wait for the target task to be executed and send the second instruction, and the data processing module 22 will record the execution log of the target task after obtaining the second instruction.
[0074] In this method, when the arbitration module 21 determines that the target task currently executed by the embedded operating system is a real-time task, it delays the first time period to send the second instruction so that the data processing module 22 records the execution log of the target task according to the second instruction, thereby reducing the burden on the CPU and ensuring the real-time performance of the embedded operating system.
[0075] The following is an introduction to the initialization method of the log recording method provided in the embodiment of the present application. If the log recording folder and the log configuration file exist at the same time, the initialization module obtains the number of log recording files in the log recording folder; wherein the log configuration file is used to record the number of each log recording file created, and if the number of log recording files is less than the number threshold, the initialization module creates the tth log recording file; wherein the number threshold is the maximum number of log recording files allowed to exist in the log recording folder, and the initialization module records the number of the tth log recording file as t in the log configuration file.
[0076] Specifically, the execution log of the above-mentioned target task needs to be recorded (stored) in a log record file, and one log record file stores one execution log, the log record file is stored in a log record folder, and the number of each log record file is created by a log configuration file. Therefore, before recording the execution log of the target task, the initialization module needs to first determine whether the log record folder and the log configuration file both exist. If so, it means that the log record folder already has a log record file with an execution log recorded. At this time, the initialization module needs to continue to determine whether the number of log record files is less than the number threshold. If so, it means that the storage space of the current log record folder can at least accommodate a log record file with an execution log recorded. At this time, the initialization module creates the tth log record file for recording (storing) the tth execution log, and records the number of the tth log record file as t in the log configuration file. The following example illustrates this method. The maximum number of log record files allowed to exist in the log record folder (number threshold) is 100. There are 30 log files containing execution logs in the current log folder. It can be seen that the number of log files is less than the number threshold. At this time, the initialization module creates the 31st log file to record (store) the 31st execution log, and records the number of the 31st log file as 31 in the log configuration file.
[0077] In this method, the initialization module first determines whether the log recording folder and the log configuration file exist before recording the execution log of the target task. If so, it continues to determine whether the number of log recording files is less than the number threshold. If so, it creates the tth log recording file to record (store) the tth execution log. Among them, this method opens the log recording folder through the opendir function to determine whether the log recording folder exists. If it does not exist, the log recording folder is created through the mkdir function. The number threshold is obtained by querying the log recording folder through the statfs function. This method avoids the situation where the execution log cannot be recorded and overflows the system due to insufficient storage space in the log recording folder. This method ensures the normal execution of the logging work, reduces the overflow rate of the execution log, and improves the integrity of the execution log of the target task in the log recording file.
[0078] In one implementation, if the log record folder exists and the log configuration file does not exist, the initialization module creates the log configuration file and the first log record file; the initialization module records the number of the first log record file as 1 in the log configuration file.
[0079] Specifically, in this method, the initialization module determines that the log record folder exists and the log configuration file does not exist, which means that the current log record folder does not have a log record file that records the execution log. At this time, the initialization module needs to create a log configuration file and the first (first) log record file for recording (storing) the first execution log. And the number of the first log record file is recorded as 1 in the log configuration file.
[0080] In this method, the initialization module determines that the log recording folder exists but the log configuration file does not exist, then the initialization module creates the log configuration file and the first log recording file for recording the first execution log. The purpose of this setting is to prepare for the recording of the execution logs of subsequent target tasks, avoid the situation where the execution logs have nowhere to be stored, and ensure the normal execution of the log recording work.
[0081] In one implementation, if the number of log record files is equal to the number threshold, the initialization module deletes some or all of the log record files and creates the tth log record file; the initialization module records the number of the tth log record file as t in the log configuration file.
[0082] Specifically, in this method, if the initialization module determines that the number of log files is equal to the number threshold, it means that the storage space of the current log folder is full. At this time, the initialization module needs to read some or all log files in the log folder through the readdir function, delete the read log files, create the tth log file, and record the number of the tth log file as t in the log configuration file.
[0083] This method avoids the situation where the execution log cannot be recorded and overflows the system due to insufficient storage space in the log recording folder, ensures the normal execution of the log recording work, reduces the overflow rate of the execution log, and improves the integrity of the execution log of the target task in the log recording file.
[0084] The following is an introduction to the creation method of the message queue. The above-mentioned execution log includes a text log and a data flow log. The data processing module 22 obtains the execution log. If the execution log is a text log, the initialization module creates a text log message queue according to the number of text logs and the memory occupied; if the execution log is a data flow log, the initialization module creates a data flow log message queue according to the number of data flow logs and the memory occupied.
[0085] Specifically, the above-mentioned data flow log includes 1553B log, network log and switch log. When creating a data flow log message queue, it is necessary to pre-set the number of the maximum data flow logs that the data flow log message queue can store and the maximum byte length (memory occupied) of each data flow log, so as to avoid the number of data flow logs obtained by the data processing module 22 exceeding the number of the maximum data flow logs that the data flow log message queue can store, or the memory occupied by each data flow log exceeds the maximum byte length (memory occupied) of each data flow log that the data flow log message queue can store. When creating a text log message queue, it is necessary to pre-set the number of the maximum text logs that the text log message queue can store and the maximum byte length (memory occupied) of each text log, so as to avoid the number of text logs obtained by the data processing module 22 exceeding the number of the maximum text logs that the text log message queue can store, or the memory occupied by each text log exceeds the maximum byte length (memory occupied) of each text log that the text log message queue can store.
[0086] In addition, when creating a data flow log message queue and a text log message queue, the "first in, first out, last in, last out" principle must be set to ensure that the data flow logs are output from the data flow log message queue in the order in which they are input into the data flow log message queue, and the text logs are output from the text log message queue in the order in which they are input into the text log message queue. For example, if the order in which the data flow logs are input into the data flow log message queue is data flow log 1, data flow log 2, and data flow log 3, then the order in which the data flow logs are output from the data flow log message queue is still data flow log 1, data flow log 2, and data flow log 3; if the order in which the text logs are input into the text log message queue is text log 1, text log 2, and text log 3, then the order in which the text logs are output from the text log message queue is still text log 1, text log 2, and text log 3. In real scenarios, the number and memory of data flow logs are greater than the number and memory of text logs, so when creating a data flow log message queue, the storage space capacity of the data flow log message queue should be set larger than that of the text log message queue.
[0087] The data flow log message queue created in this way reduces the overflow rate of the data flow log, ensures that the data flow log enters and leaves the data flow log message queue in an orderly manner, and ensures the normal execution of the log recording work. The text log message queue created in this way reduces the overflow rate of the text log, ensures that the text log enters and leaves the text log message queue in an orderly manner, and ensures the normal execution of the log recording work.
[0088] The following describes the recording method of the execution log of the target task. If the execution log is a data flow log, the data processing module 22 determines the type, generation time, ID and byte length of the data flow log according to the content of the data flow log recorded by the data flow log message queue; the data processing module 22 records the content, type, generation time, ID and byte length of the data flow log in the form of binary data in the log record file; if the execution log is a text log, the data processing module 22 records the content and generation time of the text log recorded by the text log message queue in the form of text in the corresponding log record file.
[0089] Specifically, data stream log message queue and text log message queue are both a kind of data caching mechanism, and can also guarantee the transmission of data when the embedded operating system load is high. The content of data stream log is stored in the data stream log message queue in binary data form, and data processing module 22 parses the content of data stream log, obtains the type, generation time, ID and byte length of the data stream log, and splices the type, generation time, ID and byte length of the data stream log with the content of data stream log to form a complete data stream log in binary data form. Data processing module 22 stores the data stream log in complete binary data form in the log record file. The content of text log is stored in the text log message queue in binary data form, and data processing module 22 parses the content and generation time of text log, obtains the content and generation time of text log in text form, and stores the content and generation time of text log in text form in the log record file. Wherein, the text log in the log record file is readable.
[0090] In this method, the data flow log is stored in the log record file in the form of binary data, which is convenient for the embedded operating system to call, and the text log is stored in the log record file in the form of readable text, which is convenient for the staff to view and timely discover the status and problems when the embedded operating system executes the target task.
[0091] In one embodiment, if the target task executed by the embedded operating system is a shutdown task, the data processing module 22 stops recording the execution log of the target task, and stops obtaining the first instruction and the second instruction sent by the arbitration module 21, deletes the text log message queue, deletes the data flow log message queue, and closes the log record folder.
[0092] In this method, since the target task executed by the embedded operating system is a shutdown task, after the target task is completed, the embedded operating system is in a shutdown state and no longer executes any target task, so there is no need to record the log. The data processing module 22 stops obtaining the first instruction and the second instruction sent by the arbitration module 21, deletes the text log message queue, deletes the data flow log message queue, and closes the log record folder, thereby avoiding excessive waste of system resources.
[0093] Based on the above method embodiment, the present application embodiment provides a log recording device, such as Figure 2 As shown, Figure 2 A schematic diagram of the structure of a log recording device provided in an embodiment of the present application. The device includes an arbitration module 21 and a data processing module 22. The arbitration module 21 and the data processing module 22 are applied to an embedded operating system. The functions of each module of the device are as follows:
[0094] The arbitration module 21 is used to obtain the associated information of the target task being executed by the embedded operating system; wherein the target task includes: a real-time task and a non-real-time task, and the priority of the non-real-time task is lower than the priority of the real-time task;
[0095] The arbitration module 21 is further used to determine whether the target task is a non-real-time task according to the description of the target task in the associated information, and obtain a first determination result;
[0096] The arbitration module 21 is further configured to determine whether the real-time task stops running if the first determination result indicates that the target task is a non-real-time task, thereby obtaining a second determination result;
[0097] The arbitration module 21 is further configured to send a first instruction to the data processing module if the second judgment result indicates that the real-time task stops running;
[0098] The data processing module 22 is used to record the execution log of the target task according to the first instruction;
