[0081] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be 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.

[0082] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which this application belongs; the terms used herein are only for the purpose of describing specific embodiments and are not intended to limit this application; the term "including" and any variation thereof in the specification and claims of this application and the above drawings are intended to cover non-exclusive inclusion.

[0083] Referring to "embodiments" herein means that the specific features, structures or characteristics described in connection with the embodiments may be included in at least one embodiment of the present application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art explicitly and implicitly understand that the embodiments described herein may be combined with other embodiments.

[0084] In the description of the embodiments of the present application, the term "and / or" is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can mean: A exists alone, A and B exist simultaneously, and B exists alone. In the description of the embodiments of the present application, the term "plurality" refers to two or more (including two), unless otherwise specifically defined.

[0085] Load monitoring is the process of real-time monitoring and analysis of the workload borne by a system or device during operation.

[0086] Taking an embedded device as an example, load monitoring, as a key technology to ensure the stable operation of the device, plays a crucial role. The microcontroller unit (MCU), as the "brain" of the embedded device, undertakes the important responsibilities of executing various task instructions and coordinating the work of each module of the device. Accurately obtaining the load information of the MCU (such as the time ratio of the MCU scheduling tasks) is one of the core objectives of the load monitoring of the embedded device.

[0087] In the related art, the MCU needs to calculate the load information according to the scheduling information of different tasks. During the process of calculating the load information, the MCU needs to consume a large amount of additional computing resources and processing time to execute the relevant algorithms. However, in some embedded application scenarios with high real-time requirements, such as industrial robot control, autonomous driving assistance systems, etc., the MCU itself needs to quickly process a large amount of sensor data and control instructions. At this time, performing complex load information calculations will undoubtedly further increase the load of the MCU. This will not only lead to a decrease in the operating efficiency of the MCU, but may also cause problems such as system response delay and task execution timeout due to excessive resource consumption, seriously affecting the stability of the device's own operation, and even may cause device failures, resulting in immeasurable losses.

[0088] Therefore, the load monitoring process in the related art consumes MCU resources, increases the MCU load, and reduces the stability of the device's own operation.

[0089] In one embodiment, a load monitoring method is provided. This method is applied to Figure 1 the load monitoring system therein. The load monitoring system 100 includes an embedded device 102, an instruction processing device 104, and an external computer device 106. Among them, the embedded device 102 and the external computer device 106 are communicatively connected through the instruction processing device 104.

[0090] Among them, the embedded device 102 refers to an electronic device that runs an application program to implement corresponding service functions. The instruction processing device 104 is an intermediate device for realizing data transmission and analysis between the embedded device 102 and the external computer device 106. The external computer device 106 is a computer device independent of the embedded device 102.

[0091] Exemplarily, the embedded device 102 can be a new energy vehicle equipped with a battery management application program, and the battery management application program can be used to implement the management of the vehicle battery, such as battery data collection, thermal runaway management, power balance management, etc. The instruction processing device 104 can be a parser, and the parser can also include a debugger. The external computer device 106 can be a host computer of the embedded device 102.

[0092] The instruction processing device 104 is communicatively connected to the embedded device 102 and the external computer device 106 respectively through a communication interface. Exemplarily, the communication interface can be a serial port (SP), a universal serial bus (USB) interface, or a controller area network (CAN) bus interface. In this embodiment, the type of the communication interface between the instruction processing device 104 and the embedded device 102 and the external computer device 106 is not specifically limited, as long as the communication requirements are met.

[0093] The process of the embedded device 102 running an application program to implement corresponding service functions is the process of executing tasks through a scheduler. Different service functions correspond to different types of tasks. The embedded device 102 can schedule each task by executing the scheduler. In the case of scheduling each task, the scheduling information of each task is alternately stored in different half areas of the circular storage area, and a completion flag is marked for any one of the half areas when any one of the half areas is full.

[0094] The instruction processing device 104 can, under the indication of the completion flag, obtain the scheduling information stored in any one of the half areas and send the scheduling information to the external computer device 106.

[0095] The external computer device 106 then receives the scheduling information, determines the load information of the embedded device 102 according to the scheduling information, and sends it to the embedded device 102.

[0096] The embedded device 102 correspondingly receives the load information and determines the load monitoring result of the embedded device 102 according to the load information.

[0097] The above load monitoring system 100 can realize the load monitoring of the MCU in the embedded device 102.

[0098] In one embodiment, the embodiment of the present application provides a load monitoring method. As Figure 2 shown, taking the method applied to the Figure 1 embedded device as an example, the method includes the following steps:

[0099] S210. In the case of scheduling each task by executing a scheduler, alternately store the scheduling information of each task in different half areas of the circular storage area, and mark a completion flag for any one of the half areas when any one of the half areas is full; the completion flag is used to indicate that the instruction processing device sends the scheduling information stored in any one of the half areas to the external computer device.

[0100] Among them, each task (TASK) may include a service task for the embedded device to run the loaded application program to implement the corresponding service function, or may include an idle task (Idle Task) that does not run the application program.

[0101] The scheduling information is the data information obtained by the scheduling degree for scheduling tasks. Exemplarily, the scheduling information may include the task identifier (such as ID) or task type (such as periodic task or aperiodic task) of the scheduled task, and may also include time information, such as the start time of scheduling, the completion time of scheduling, or the scheduling duration from the start of scheduling to the completion of scheduling, etc.

[0102] The circular storage area is a temporary storage area in the embedded device, and can also be referred to as a buffer. The process of storing data using the circular storage area is as follows:

[0103] Starting from a storage location in the circular storage area, data is stored along a preset circumferential direction. When the circular storage area is full, continue to use the new data to overwrite the old data starting from this starting point to continuously store data by reusing the storage area.

[0104] A half area in the circular storage area represents a partial storage area (not the entire storage area) in the circular storage area. A circular storage area may include at least two half areas. The completion flag indicates that the data storage amount in the corresponding half area reaches the full state, that is, the corresponding half area is full.

[0105] Optionally, the embedded device may, when receiving a task execution instruction, enable the scheduling degree, and schedule each task through this scheduler. For example, schedule each task in the task schedule in sequence. When scheduling, record the scheduling information obtained by the scheduling degree for scheduling each task, and store this scheduling information in a half area of the circular buffer area. At the same time, detect the data storage amount of each half area to mark a completion flag for any one of the half areas when the data storage amount reaches the full state, that is, when any one of the half areas in the circular storage area is full.

[0106] Exemplarily, after the embedded device marks the completion flag for any one of the half areas, it may send the scheduling information stored in this half area to the instruction processing device. The instruction processing device may periodically read the completion flag by polling and accessing the embedded device. When the completion flag is read, obtain the scheduling information stored in the half area corresponding to this completion flag, and then send the received / acquired scheduling information to an external computer device for the external computer device to determine the load information of the embedded device based on this scheduling information.

[0107] S220. Receive the load information of the embedded device determined by the external computer device according to the scheduling information.

[0108] Among them, the load information of the embedded device is used to characterize the load situation of the MCU in the embedded device when executing tasks. Exemplarily, the load information may include the duration of executing each task, the total duration of executing different / same tasks within a preset period, the time ratio of executing different / same tasks in the preset period, and so on.

[0109] Optionally, the external computer device can statistically determine at least one of the duration of each task executed by the MCU in the embedded device, the total duration of executing all / same tasks within a preset period, and the time ratio of the total duration of executing all / same tasks within the preset period in the preset period as the load information of the embedded device, and send it to the instruction processing device, and then the instruction processing device sends the load information of the embedded device to the embedded device. The embedded device correspondingly receives the load information of the embedded device determined by the external computer device.

[0110] S230. Determine the load monitoring result of the embedded device according to the load information.

[0111] Optionally, after obtaining the load information of the embedded device determined by the external computer device, the embedded device can directly use the load information as the load monitoring result of the embedded device, or further process the load information to determine the load monitoring result of the embedded device.

[0112] Exemplarily, taking the time ratio of the total duration of the MCU executing the same task in the preset period as the load information as an example, the obtained load information of the embedded device includes the time ratio T1 of executing task A. The embedded device can compare T1 with the preset time ratio T to determine the load monitoring result of the embedded device according to the comparison result. For example, when T1 > T, it is determined that the load monitoring result of the embedded device is that the load of the embedded device for task A exceeds the load threshold; when T1 ≤ T, it is determined that the load monitoring result of the embedded device is that the load of the embedded device for task A does not exceed the load threshold.

[0113] In the embodiments of the present application, when the embedded device schedules each task by executing a scheduler, the scheduling information of each task is alternately stored in different half areas of the circular storage area, and when any one of the half areas is full, a completion flag is marked for any one of the half areas, and the load information of the embedded device determined by the external computer device according to the scheduling information is received, so as to determine the load monitoring result of the embedded device according to the load information; the completion flag is used to instruct the instruction processing device to send the scheduling information stored in any one of the half areas to the external computer device; in the above method, the scheduling information in the circular storage area is sent to the external computer device, and the external computer device determines the load information of the embedded device based on the scheduling information, and then obtains the load monitoring result, realizing the calculation of the off-chip load information without the embedded device consuming its own resources. Therefore, the occupation of the MCU resources of the embedded device is reduced, the MCU load is reduced, and the stability of the embedded device itself during operation is improved.

[0114] The scheduling information of the task includes a task identifier, an entry timestamp for scheduling the task, and an exit timestamp for completing the task scheduling. Based on this, in one embodiment, as Figure 3 shown, in the above S210, when scheduling each task by executing a scheduler, alternately storing the scheduling information of each task in different half areas of the circular storage area includes:

[0115] S310. For any task, when scheduling the task, obtain the task identifier of the task, the entry timestamp for starting to schedule the task, and the exit timestamp for completing the task scheduling.

[0116] Among them, the task identifier is used to distinguish different tasks, and the task identifiers of different tasks are different, while the task identifiers of the same task are the same. Exemplarily, the task identifier can be the task ID. The entry timestamp (T start ) represents the moment when the scheduler starts to schedule the task, and the exit timestamp (T end ) represents the moment when the scheduler completes the scheduling of the task.

[0117] Optionally, the embedded device synchronously monitors the scheduling situation of each task during the scheduling process of each task. For any task being scheduled, when scheduling the task, obtain the task identifier of the task, and determine the moment when the scheduling of the task starts as the entry timestamp, and determine the moment when the scheduling of the task is completed as the exit timestamp.

[0118] S320. Determine the current half area according to the storage status of different half areas in the circular storage area.

[0119] Among them, the current half area represents the half area used to store the newly obtained scheduling information.

[0120] Optionally, after the embedded device obtains new scheduling information, it can determine the half region whose storage state meets the preset demand state among different half regions according to the storage states of different half regions in the circular storage area as the half region for storing the newly obtained scheduling information, that is, the current half region.

[0121] Exemplarily, the storage state of the half region can be represented by a storage state pointer, and the storage state pointer is used to point to the current storage position reached by the half region. After obtaining new scheduling information, the embedded device can read the storage state pointers of each half region in the circular storage area and determine the half region whose storage state pointer points to a non-half region end point as the current half region.

[0122] S330. Store the task identifier, entry timestamp, and exit timestamp as the scheduling information of the task in the current half region.

[0123] Optionally, after determining the current half region, the embedded device uses the task identifier, entry timestamp, and exit timestamp obtained from the scheduled task as the scheduling information of the scheduled task and stores them in the determined current half region.

[0124] In the embodiments of the present application, for any task, when scheduling the task, obtain the task identifier of the task, the entry timestamp and exit timestamp for scheduling the task, and determine the current half region according to the storage states of different half regions in the circular storage area, so as to store the task identifier, entry timestamp, and exit timestamp as the scheduling information of the task in the current half region; in the above method, using the task identifier, entry timestamp, and exit timestamp of the scheduled task as the scheduling information obtained from scheduling the task realizes the full-time recording of the task scheduling process, provides a rich data basis for subsequent determination of load information, and can improve the diversity of the determined load information.

[0125] In the case where the circular storage area includes two half regions, namely the first half region and the second half region, in one embodiment, as Figure 4 shown, the above S320. Determine the current half region according to the storage states of different half regions in the circular storage area, includes:

[0126] S410. Obtain the storage flag bits of the first half region and the second half region.

[0127] Wherein, the storage flag bit can be used to characterize the storage state of the half region. The storage flag bit can be a completion flag or a non-completion flag. The completion flag characterizes that the storage state of the half region reaches the full storage state, and the non-completion flag characterizes that the storage state of the half region does not reach the full storage state. Exemplarily, the completion flag is 1, and the non-completion flag is empty or 0.

[0128] Optionally, when determining the current half region of the circular storage region, the embedded device can respectively obtain the storage flag bits of the first half region and the second half region in the circular storage region, that is, read the flag information in the storage flag bits.

[0129] S420. When one of the storage flag bits of the first half region and the second half region is a completion flag and the other is a non-completion flag, determine the half region with the non-completion flag as the current half region.

[0130] Optionally, after obtaining the storage flag bits of the first half region and the second half region, when one of the storage flag bits of the first half region and the second half region is a completion flag and the other is a non-completion flag, the embedded device can determine the half region with the non-completion flag as the current half region.

[0131] It should be noted that the half region with the completion flag indicates that the half region has been fully stored, while the half region with the non-completion flag indicates that the half region has not been fully stored. It may be the half region that is currently used for storing scheduling information or the idle half region that has not stored scheduling information yet. When one of the two half regions is fully stored and the other is not, select the half region that is not fully stored as the current half region for storing new scheduling information.

[0132] When there are three or more half regions in the circular storage region, if the storage flag bit of one of the half regions is a completion flag and the completion flag bits of the other half regions are all non-completion flags, the embedded device will use the next half region along the preset circumferential direction and located after the half region with the completion flag as the current half region.

[0133] S430. When the storage flag bits of the first half region and the second half region are both non-completion flags, determine the current half region according to the storage status pointers of the first half region and the second half region.

[0134] Among them, in addition to the storage flag bit that can be used to represent the storage status of the half region, the storage status pointer can also be used to represent the storage status of the half region, specifically used to point to the current storage position reached by the half region. The situation where the storage flag bits of the first half region and the second half region are both non-completion flags corresponds to the scenario where the circular storage region has not stored scheduling information, or has just started storing scheduling data, or the stored data has been completely cleared.

[0135] Optionally, when the storage flag bits of the first half region and the second half region are both non-completion flags, the embedded device can further read the storage status pointers of the first half region and the second half region to determine the current half region in the first half region and the second half region.

[0136] In an optional embodiment, determining the current half region according to the storage status pointers of the first half region and the second half region in S430 above includes:

[0137] Based on the storage status pointers of the first half-region and the second half-region, determine, in the first half-region and the second half-region, the half-region where the storage status pointer points to a non-half-region end point as the current half-region.

[0138] Wherein, the half-region end point is the last storage position of the corresponding half-region in the preset wrapping direction, and the non-half-region end point is any storage position of the corresponding half-region that is not the last storage position in the preset wrapping direction, that is, any storage position between the start point and the end point (including the start point but not including the end point).

[0139] It should be noted that the storage position pointed to by the storage status pointer changes continuously as data is stored. After the storage status pointer points to the half-region end point, if new data continues to be stored in this half-region, the storage status pointer of this half-region will point to the storage position reached after the new data is stored again.

[0140] Optionally, obtaining the storage status pointers of the first half-region and the second half-region means obtaining the storage positions pointed to by the storage status pointers of the first half-region and the second half-region. The embedded device can respectively determine whether the storage status pointers of the first half-region and the second half-region point to storage positions that are not the half-region end points, and select the half-region that points to the non-half-region end point as the current half-region. When the storage status pointers of both the first half-region and the second half-region point to non-half-region end points, that is, the storage status pointers of both the first half-region and the second half-region point to the half-region start points, the embedded device can select any half-region or a preset half-region (such as the first half-region or the second half-region) in the first half-region and the second half-region as the current half-region.

[0141] In the case where there are three or more half-regions in the circular storage area, if the completion flag bits of all half-regions are non-completion flags, the embedded device obtains the storage status pointers of each half-region, and determines, among all half-regions, the half-region where the storage status pointer points to a non-half-region end point as the current half-region. When the storage status pointers of all half-regions point to non-half-region end points, that is, the storage status pointers of all half-regions point to the half-region start points, the embedded device can select any half-region or a preset half-region in all half-regions as the current half-region. The preset half-region can be any half-region in the circular storage area.

[0142] In the embodiments of the present application, storage flag bits of a first half region and a second half region are obtained. When one of the storage flag bits of the first half region and the second half region is a completion flag and the other is a non-completion flag, the half region with the non-completion flag is determined as the current half region. And when the storage flag bits of both the first half region and the second half region are non-completion flags, the current half region is determined according to the storage state pointers of the first half region and the second half region. Specifically, the half region in which the storage state pointer points to a non-half region end point can be determined in the first half region and the second half region as the current half region. In the above method, the current half region is determined in the first half region and the second half region by combining the storage flag bits and the storage state pointers, which is adapted to the diverse storage states of the first half region and the second half region, and improves the efficiency and convenience of determining the current half region.

[0143] To obtain a task identifier, an entry timestamp, and a contact timestamp, in one embodiment, as Figure 5 shown, obtaining the task identifier of the task, the entry timestamp for starting to schedule the task, and the exit timestamp for completing the scheduling of the task in S310 above includes:

[0144] S510. Invoke a pre-hook function to obtain the task identifier of the scheduled task, and obtain the moment when the scheduled task starts to be scheduled, denoted as the entry timestamp.

[0145] Among them, the pre-hook (PreHook) function is a callback function that is triggered and invoked before scheduling a task.

[0146] Optionally, before an embedded device schedules a task through a scheduler, the pre-hook function is triggered. By invoking the pre-hook function, the scheduling situation of the task is traced to obtain the task identifier of the scheduled task and the moment when the scheduled task starts to be scheduled, and the moment when the scheduled task starts to be scheduled is denoted as the entry timestamp.

[0147] S520. Invoke a post-hook function to obtain the moment when the scheduled task is scheduled to completion, denoted as the exit timestamp.

[0148] Among them, the post-hook (PostHook) function is also a callback function that is triggered and invoked after scheduling a task.

[0149] Optionally, after an embedded device schedules a task through a scheduler, the post-hook function is triggered. By invoking the post-hook function, it is traced whether the task has been scheduled to completion, that is, has been executed, to obtain the moment when the scheduled task is scheduled to completion, and the moment when the scheduled task is scheduled to completion is denoted as the exit timestamp.

[0150] In the embodiments of the present application, a pre - hook function is called to obtain the task identifier of the scheduled task, and the moment when the scheduled task starts to be scheduled is obtained, which is recorded as the entry - point timestamp. In addition, a post - hook function is called to obtain the moment when the scheduled task is scheduled to completion, which is recorded as the exit - point timestamp. In the above method, by calling the pre - hook function and the post - hook function respectively, without affecting the scheduler's scheduling of tasks, the scheduling situation of the scheduled task and whether it has been executed completely are traced, thereby improving the accuracy and reliability of the obtained task identifier, entry - point timestamp, and exit - point timestamp.

[0151] The circular storage area includes two half - areas, namely the first half - area and the second half - area. Based on this, in one embodiment, as Figure 6 shown, in S210 above, when any one of the half - areas is full, marking a completion flag for any one of the half - areas includes:

[0152] S610: When any one of the half - areas is the first half - area, mark the storage flag bit of the first half - area as the completion flag.

[0153] Among them, the storage flag bit can be used to represent the storage state of the half - area. The storage flag bit can be a completion flag or a non - completion flag. The completion flag represents that the storage state of this half - area has reached the full - storage state, and the non - completion flag represents that the storage state of this half - area has not reached the full - storage state. Exemplarily, the completion flag is 1, and the non - completion flag is empty or 0.

[0154] Optionally, when any one of the full - filled half - areas is the first half - area in the circular storage area, representing that the storage state of this first half - area has reached the full - storage state, the embedded device marks the storage flag bit of this first half - area as the completion flag.

[0155] S620: When any one of the half - areas is the second half - area, mark the storage flag bit of the second half - area as the completion flag.

[0156] Optionally, when any one of the full - filled half - areas is the second half - area in the circular storage area, representing that the storage state of this second half - area has reached the full - storage state, the embedded device marks the storage flag bit of this second half - area as the completion flag.

[0157] In the embodiments of the present application, the circular storage area includes the first half - area and the second half - area. When any one of the half - areas is the first half - area, mark the storage flag bit of the first half - area as the completion flag, and when any one of the half - areas is the second half - area, mark the storage flag bit of the second half - area as the completion flag. In the above method, when the first half - area or the second half - area is full, mark the storage flag bit of the corresponding half - area as the completion flag, so as to timely instruct the instruction - processing device to obtain the scheduling information stored in the corresponding half - area, improving the timeliness and orderliness of load monitoring.

[0158] The embedded device is also used to update the storage flag bit under the instruction of the instruction processing device. For the first half area in the circular storage area, in one embodiment, as Figure 7 shown, the above method further includes:

[0159] S710. Receive the flag bit clearing instruction for the first half area sent by the instruction processing device; the flag bit clearing instruction for the first half area is generated by the instruction processing device based on the operation of sending the scheduling information stored in the first half area to an external computer device.

[0160] Among them, the flag bit clearing instruction is used to indicate clearing the completion flag in the storage flag bit.

[0161] Optionally, when the first half area in the circular storage area is full, the embedded device marks the storage flag bit of the first half area as the completion flag. When the instruction processing device receives / reads that the storage flag bit of the first half area is marked as the completion flag, it will obtain the call information stored in the first half area, send the scheduling information stored in the first half area to an external computer device, synchronously generate the flag bit clearing instruction for the first half area, and send it to the embedded device. The embedded device correspondingly receives the flag bit clearing instruction for the first half area sent by the instruction processing device.

[0162] S720. According to the flag bit clearing instruction, clear the completion flag in the storage flag bit of the first half area.

[0163] Optionally, after the embedded device receives the flag bit clearing instruction for the first half area, it clears the completion flag in the storage flag bit of the first half area in response to the flag bit clearing instruction.

[0164] In the embodiment of the present application, receive the flag bit clearing instruction for the first half area sent by the instruction processing device, and according to the flag bit clearing instruction, clear the completion flag in the storage flag bit of the first half area; the flag bit clearing instruction for the first half area is generated by the instruction processing device based on the operation of sending the scheduling information stored in the first half area to an external computer device; in the above method, the external sending operation of the instruction processing device for the scheduling information stored in the first half area in the full state triggers the flag bit clearing instruction for the storage flag bit of the first half area, so as to instruct the embedded device to update the storage flag bit of the first half area in time, improve the orderliness of subsequent scheduling information external sending, and can correspondingly improve the accuracy of the determined load information, thereby improving the reliability of load monitoring.

[0165] For the second half area in the circular storage area, in one embodiment, as Figure 8 shown, the above method further includes:

[0166] S810. Receive the flag bit clearing instruction for the second half area sent by the instruction processing device; the flag bit clearing instruction for the second half area is generated by the instruction processing device based on the operation of sending the scheduling information stored in the second half area to an external computer device.

[0167] Optionally, when the second half area in the circular storage area is full, the embedded device marks the storage flag bit of the second half area as the completion flag. When the instruction processing device receives / reads that the storage flag bit of the second half area is marked as the completion flag, it will obtain the call information stored in the second half area, send the scheduling information stored in the second half area to the external computer device, synchronously generate the flag bit clearing instruction for the second half area, and send it to the embedded device. The embedded device correspondingly receives the flag bit clearing instruction for the second half area sent by the instruction processing device.

[0168] S820. Clear the completion flag in the storage flag bit of the second half area according to the flag bit clearing instruction.

[0169] Optionally, after the embedded device receives the flag bit clearing instruction for the second half area, it clears the completion flag in the storage flag bit of the second half area in response to the flag bit clearing instruction.

[0170] In the embodiments of the present application, receive the flag bit clearing instruction for the second half area sent by the instruction processing device, and clear the completion flag in the storage flag bit of the second half area according to the flag bit clearing instruction; the flag bit clearing instruction for the second half area is generated by the instruction processing device based on the operation of sending the scheduling information stored in the second half area to an external computer device; in the above method, the external sending operation of the scheduling information stored in the second half area in the full state by the instruction processing device triggers the flag bit clearing instruction for the storage flag bit of the second half area, so as to instruct the embedded device to update the storage flag bit of the second half area in time, improve the orderliness of subsequent scheduling information external sending, and correspondingly improve the accuracy of the determined load information, thereby improving the reliability of load monitoring.

[0171] In an optional embodiment, when the instruction processing device sends the scheduling information stored in any half area to an external computer device, the instruction processing device calls the memory access interface to access the address of the circular storage area, reads the scheduling information from the circular storage area through the data read / write register, and sends the read scheduling information to the external computer device.

[0172] Among them, the Memory Access Point (MeM-AP) is a communication interface for realizing memory access between an instruction processing device and an embedded device. The Data Read / Write Register is a data read / write interface for reading raw data in the memory, that is, reading the scheduling information stored in the circular storage area.

[0173] Exemplarily, taking the instruction processing device as a parser, the parser accesses the address of the circular storage area in the embedded device through the MeM-AP, reads the scheduling information stored in the circular storage area through the data read / write register, and sends the read scheduling information to an external computer device.

[0174] In one embodiment, the embodiment of the present application further provides a load monitoring method, as Figure 9 shown, taking the method applied to Figure 1 the external computer device in

[0175] S910. Receive the scheduling information stored in the circular storage area of the embedded device sent by the instruction processing device; the scheduling information is that when the embedded device schedules each task by executing a scheduling program, the scheduling information of each task is alternately stored in different half areas of the circular storage area, and when any half area is full, a completion flag is marked for any half area; the completion flag is used to instruct the instruction processing device to send the scheduling information stored in any half area to the external computer device.

[0176] Among them, each task (TASK) may include a service task for the embedded device to run the application program to implement the corresponding service function, or may include an idle task (Idle Task) that does not run the application program.

[0177] The scheduling information is the data information obtained by the scheduling program scheduling the tasks. Exemplarily, the scheduling information may include the task identifier (such as ID) or task type (such as periodic task or aperiodic task) of the scheduled task, or may include time information, such as the start time of scheduling, the completion time of scheduling, or the scheduling duration from the start of scheduling to the completion of scheduling, and so on.

[0178] The circular storage area is a temporary storage area in the embedded device, and can also be called a buffer. The process of storing data in the circular storage area is as follows:

[0179] Starting from a storage location in the circular storage area, data is stored along the preset circumferential direction. When the circular storage area is full, continue to use the new data to overwrite the old data starting from this starting point to continuously store data by reusing the storage area.

[0180] A half - area in the circular storage area represents a partial storage area (not the entire storage area) in the circular storage area, and a circular storage area can include at least two half - areas.

[0181] Optionally, when receiving a task execution instruction, the embedded device can enable the scheduler, and schedule each task through this scheduler. For example, schedule each task in the task schedule in sequence. When scheduling, record the scheduling information obtained by the scheduler for scheduling each task, and store this scheduling information in a half - area of the circular buffer area. At the same time, detect the data storage amount of each half - area to mark a completion flag for any one of the half - areas when the data storage amount reaches the full state, that is, when any one of the half - areas in the circular storage area is full. The instruction processing device can receive / obtain the scheduling information stored in different half - areas of the circular storage area and send this scheduling information to an external computer device. The external computer device correspondingly receives the scheduling information sent by the instruction processing device.

[0182] S920. Determine the load information of the embedded device according to the received scheduling information, and send the load information to the embedded device; the load information is used for the embedded device to determine the load monitoring result of the embedded device.

[0183] Among them, the load information of the embedded device is used to characterize the load situation of the MCU in the embedded device when executing tasks. Exemplarily, the load information can include the duration of executing each task, the total duration of executing different / the same tasks within a preset period, the time ratio of executing different / the same tasks in the preset period, and so on.

[0184] Optionally, the external computer device can statistically determine at least one of the duration of the MCU in the embedded device for executing each task, the total duration of executing all / the same tasks within a preset period, and the time ratio of the total duration of executing all / the same tasks within a preset period in the preset period as the load information of the embedded device, and send it to the instruction processing device, and then the instruction processing device sends the load information of the embedded device to the embedded device for the embedded device to determine the load monitoring result of the embedded device.

[0185] In the embodiments of the present application, an external computer device receives scheduling information stored in a circular storage area of an embedded device sent by an instruction processing device, determines the load information of the embedded device according to the received scheduling information, and sends the load information to the embedded device; the scheduling information is that when the embedded device schedules each task by executing a scheduling program, the scheduling information of each task is alternately stored in different half-areas of the circular storage area, and a completion flag is marked for any one of the half-areas when any one of the half-areas is full; the completion flag is used to instruct the instruction processing device to send the scheduling information stored in any one of the half-areas to the external computer device; the load information is used for the embedded device to determine the load monitoring result of the embedded device; in the above method, the external computer device receives the scheduling information sent by the embedded device to determine the load information of the embedded device by using the resources available to the external computer device, and then obtains the load monitoring result, realizing the calculation of the off-chip load information without the embedded device consuming its own resources, thus reducing the occupation of the MCU resources of the embedded device, reducing the MCU load, and improving the stability of the operation of the embedded device itself.

[0186] In one embodiment, in order to obtain the load information of the embedded device, as Figure 10 shown, determining the load information of the embedded device according to the received scheduling information in S920 above includes:

[0187] S1010. Determine the load information of different tasks within a reference period according to the received scheduling information.

[0188] Wherein, the reference period is any preset time period.

[0189] Optionally, the external computer device can determine the tasks scheduled within the reference period in the received scheduling information, and then determine the load information of different tasks within the reference period. Among them, the tasks scheduled within the reference period are the tasks that start scheduling and complete scheduling within the reference period.

[0190] Exemplarily, the scheduling information includes a task identifier, an entry timestamp, and an exit timestamp. The scheduling information received by the external computer device is sorted in chronological order as follows:

[0191] T i-start1 、T i-end1 、T j-start1 、T j-end1 、T k-start1 、T k-end1 。

[0192] i, j, k represent task identifiers, T start represents the entry timestamp, T end represents the exit timestamp, and 1 represents the first scheduling.

[0193] Taking the reference period [T1, T2] as an example, when T1 is earlier than T i-start1 , and T2 is later than T k-end1 , the embedded device can determine that tasks i, j, and k are all scheduled within the reference period [T1, T2]. The embedded device can determine the load information of tasks i, j, and k respectively based on the above scheduling information.

[0194] S1020. Determine the load information of the embedded device according to the load information of different tasks.

[0195] Optionally, after obtaining the load information of each task scheduled within the reference period, the external computer device can determine the load information of the embedded device within the reference period based on the load information of each task.

[0196] Exemplarily, the external computer device can directly use the load information of each task within the reference period as the load information of the embedded device within the reference period, or can obtain the sum of the load information of each task within the reference period as the load information of the embedded device within the reference period.

[0197] In the embodiments of the present application, the load information of different tasks within the reference period is determined according to the received scheduling information, and the load information of the embedded device is determined according to the load information of different tasks; in the above method, the scheduling information received by the external computer device can be stored for a long time without being overwritten, and the external computer device can determine the load information of tasks at any time period according to the received scheduling information, so the time limitation is reduced and the flexibility of the time period for determining the load information is improved.

[0198] The load information can be characterized by the time ratio. In the case where the scheduling information includes the task identifier, the entry timestamp, and the exit timestamp, in one of the embodiments, as Figure 11 shown, the above S1010. Determine the load information of different tasks within the reference period according to the received scheduling information, includes:

[0199] S1110. Determine the running duration of each task scheduled within the reference period according to the scheduling information; the running duration is the time difference between the entry timestamp and the exit timestamp of each task scheduled.

[0200] Optionally, the external computer device can determine the tasks scheduled within the reference period from the received scheduling information, and for each task scheduled within the reference period, obtain the time difference between the entry timestamp and the exit timestamp of the task as the running duration of the task.

[0201] S1120. For a task corresponding to the same task identifier, obtain the ratio of the sum of the running durations of each scheduling to the total duration of the reference period as the load information of the task.

[0202] Optionally, after obtaining the running durations of each scheduling of each task within the reference period, an external computer device can calculate the sum of the running durations of each scheduling of the task corresponding to the same task identifier, and obtain the ratio of the running duration to the total duration of the reference period as the load information of the task.

[0203] Exemplarily, taking the total duration T of the reference period, and the tasks within the reference period including TaskA, TaskB, and TaskC as examples, and obtaining that the running duration of TaskA being scheduled is TA1, the running durations of TaskB being scheduled are TB1 and TB2, and the running durations of TaskC being scheduled are TC1, TC2, and TC3 as examples, the embedded device can obtain the load information of TaskA as TA1 / T, the load information of TaskB as (TB1 + TB2) / T, and the load information of TaskC as (TC1 + TC2 + TC3) / T.

[0204] In addition to the load information of the task, the external computer device can also determine the running state of the task. The external computer device can obtain the reference duration of the task corresponding to the same task identifier being called based on the running durations of each task being called within the reference period, so as to determine the running state of the task corresponding to the same task identifier according to the reference duration.

[0205] Exemplarily, the reference duration can be the average running duration, or the maximum running duration or the minimum running duration.

[0206] Optionally, after the external computer device obtains the running durations of each task being called within the reference period, it can extract the running durations of each call of the task corresponding to the same task identifier, calculate the average running duration as the reference duration of the task, and then compare the reference duration with a preset duration range, and determine the running state of the task according to the comparison result. Exemplarily, when the reference duration is within the preset duration range, determine that the running state of the task is normal; otherwise, when the reference duration is not within the preset duration range, determine that the running state of the task is abnormal.

[0207] The external computer device can also determine the scheduling status of the embedded device for task scheduling. The external computer device can obtain the scheduling order of the tasks scheduled according to the reference period, match the scheduling order with the preset order, and determine the scheduling status of the embedded device for task scheduling according to the matching result. Exemplarily, when the scheduling order is the same as the preset order, that is, they match, it is determined that the scheduling status of the embedded device for task scheduling is normal; conversely, when the scheduling order is different from the preset order, that is, they do not match, it is determined that the scheduling status of the embedded device for task scheduling is abnormal.

[0208] It should be noted that the external computer device not only sends load information to the embedded device through the instruction processing device, but also, when obtaining the running status of the task and / or the scheduling status of the embedded device for task scheduling, can synchronously send the running status of the task and / or the scheduling status of the embedded device for task scheduling to the embedded device through the instruction processing device.

[0209] In one embodiment, the present application also provides a load monitoring system, as Figure 1 shown, the load monitoring system 100 includes an embedded device 102, an instruction processing device 104, and an external computer device 106. The embedded device 102 and the external computer device 106 are communicatively connected through the instruction processing device 104;

[0210] The embedded device 102 is configured to alternately store the scheduling information of each task into different half-areas of the circular storage area when scheduling each task by executing a scheduler, mark a completion flag for any one of the half-areas when any one of the half-areas is full, and receive the load information of the embedded device 102 sent by the external computer device 106, and determine the load monitoring result of the embedded device 102 according to the load information of the embedded device 102;

[0211] The instruction processing device 104 is configured to obtain the scheduling information stored in any one of the half-areas under the indication of the completion flag and send it to the external computer device 106;

[0212] The external computer device 106 is configured to determine the load information of the embedded device 102 based on the received scheduling information and send it to the embedded device 102.

[0213] In the above load monitoring system, the embedded device 102 and the external computer device 106 are respectively used to implement a load monitoring method. The specific process is detailed in the foregoing related embodiments and will not be elaborated here.

[0214] For the convenience of those skilled in the art, the load monitoring method provided by the present application is introduced in detail below, taking the load monitoring system in Figure 1 as an example, asFigure 12 As shown, the method may include:

[0215] S1201. For any task scheduled by the embedded device through the execution of the scheduler, when scheduling the task, call the pre-hook function to obtain the task identifier of the scheduled task, and obtain the moment when the scheduled task starts to be scheduled, denoted as the entry point timestamp, and call the post-hook function to obtain the moment when the scheduled task is scheduled to completion, denoted as the exit point timestamp;

[0216] S1202. When one of the storage flag bits in the first half and the second half of the circular storage area is the completion flag and the other is the non-completion flag, determine the half area with the non-completion flag as the current half area;

[0217] S1203. When the storage flag bits of both the first half and the second half are non-completion flags, determine, according to the storage state pointers of the first half and the second half, the half area in which the storage state pointer points to a non-half area end point as the current half area;

[0218] S1204. Store the task identifier, entry point timestamp, and exit point timestamp of the scheduled task as the scheduling information of the task into the current half area; the first half and the second half alternate as the current half area;

[0219] S1205. When any half area in the circular storage area is full, mark the storage flag bit of that any half area as the completion flag;

[0220] S1206. When the instruction processing device reads that the storage flag bit of the first half area is the completion flag, obtain the scheduling information stored in the first half area and send it to the external computer device;

[0221] S1207. When the instruction processing device reads that the storage flag bit of the second half area is the completion flag, obtain the scheduling information stored in the second half area and send it to the external computer device;

[0222] S1208.
