[0002] Ultrasound systems, including ultrasound equipment, are widely used in fields such as surgery, where imaging stability is crucial. Current ultrasound equipment is prone to malfunctions such as black screens and system crashes due to graphics card errors, resulting in relatively poor stability. Summary of the Invention

[0003] In view of this, the purpose of this application is to provide a graphics card task switching method, a graphics card task switching device, an ultrasonic device, and a computer-readable storage medium, thereby improving the stability of the ultrasonic device.

[0004] To address the aforementioned technical problems, this application provides a graphics card task switching method, applied to an ultrasound device, comprising:

[0005] According to the preset configuration, the candidate order among at least two graphics cards in the ultrasound device is determined;

[0006] According to the preset configuration, the task of processing ultrasonic display information corresponding to each graphics card is determined, and the corresponding task is executed by each graphics card.

[0007] If an anomaly is detected in the target graphics card, a candidate graphics card is determined using the candidate order, and the target task of the target graphics card is executed using the candidate graphics card.

[0008] Optionally, the task of processing ultrasound display information includes ultrasound image display tasks;

[0009] The step of determining the task for processing ultrasonic display information corresponding to each graphics card according to the preset configuration includes:

[0010] If the preset configuration is a task splitting configuration, then a number of sub-tasks are determined based on the task splitting configuration to split the ultrasound image display task.

[0011] The subtasks are assigned to several different graphics cards.

[0012] Optionally, the task of processing ultrasound display information includes an ultrasound image display task, which includes an ultrasound image display subtask and a backup task.

[0013] The step of determining the task for processing ultrasonic display information corresponding to each graphics card according to the preset configuration includes:

[0014] If the preset configuration is a task backup configuration, then the ultrasound image display task is determined to be the task corresponding to the first graphics card, and the backup task is determined to be the task corresponding to the second graphics card.

[0015] Optionally, the step of using the target candidate graphics card to execute the target task of the target graphics card includes:

[0016] Determine whether the first candidate task of the target candidate graphics card has an overlapping part with the target task;

[0017] If there are duplicate parts, the duplicate parts in the first candidate task are removed to obtain the second candidate task;

[0018] The second candidate task and the target task are executed using the target candidate graphics card.

[0019] Optionally, it also includes:

[0020] If the ultrasound device is detected to be activated, at least two initialization threads are constructed; the number of initialization threads is greater than or equal to the number of graphics cards.

[0021] The corresponding graphics cards are initialized in parallel using the respective initialization threads.

[0022] Optionally, after executing the target task of the target graphics card using the candidate target graphics card, the method further includes:

[0023] A task switching record is generated based on the target graphics card and the target candidate graphics card;

[0024] The method further includes:

[0025] If the cause of the abnormality of the target abnormal graphics card is repaired, the current candidate graphics card corresponding to the target abnormal graphics card is determined using the task switching record; the target abnormal graphics card can be any graphics card that has malfunctioned.

[0026] Delete the target candidate task from the current candidate task corresponding to the current candidate graphics card; the target candidate task is a task specified by the preset configuration that belongs exclusively to the target abnormal graphics card;

[0027] The target abnormal graphics card is used to execute the task assigned by the preset configuration.

[0028] Optionally, the cause of the detected abnormality in the target graphics card is fixed, including:

[0029] Determine the anomaly type of the target abnormal graphics card;

[0030] If the anomaly type is a software type, then the software environment of the target abnormal graphics card is reconstructed, and after the software environment is reconstructed, it is determined that the cause of the anomaly has been fixed;

[0031] If the anomaly type is not a software type, then monitor the anomaly status, and determine that the cause of the anomaly has been fixed when the anomaly status returns to normal.

[0032] This application also provides a graphics card task switching device, applied to an ultrasonic device, comprising:

[0033] The determination module is used to determine the candidate order among at least two graphics cards in the ultrasound device according to a preset configuration;

[0034] An execution module is used to determine, according to the preset configuration, the task of processing ultrasonic display information corresponding to each of the graphics cards, and to execute the corresponding task using each of the graphics cards.

[0035] The switching module is used to determine a target candidate graphics card based on the candidate order if an anomaly is detected in the target graphics card, and to execute the target task of the target graphics card using the target candidate graphics card.

[0036] This application also provides an ultrasonic device, including a memory and a processor, wherein:

[0037] The memory is used to store computer programs;

[0038] The processor is used to execute the computer program to implement the above-described graphics card task switching method.

[0039] This application also provides a computer-readable storage medium for storing a computer program, wherein the computer program, when executed by a processor, implements the above-described graphics card task switching method.

[0040] The graphics card task switching method provided in this application is applied to ultrasound equipment. Based on a preset configuration, a candidate order is determined among at least two graphics cards in the ultrasound equipment. Also based on the preset configuration, the task corresponding to each graphics card for processing ultrasound display information is determined, and each graphics card executes its corresponding task. If an anomaly is detected in the target graphics card, a target candidate graphics card is determined using the candidate order, and the target candidate graphics card executes the target task of the target graphics card. Therefore, the ultrasound equipment using this method has at least two graphics cards, and all graphics cards work simultaneously. In the imaging task, display is the last step. The preset configuration sets the candidate order among the graphics cards. By determining the candidate order, a candidate graphics card can be identified to take over the task when one graphics card malfunctions. When the target graphics card malfunctions, to avoid affecting the imaging work of the ultrasound equipment, a target candidate graphics card is determined using the candidate order, and then the target candidate graphics card takes over from the target graphics card to execute the target task originally performed by the target graphics card. By dynamically switching computing resources (i.e. graphics cards) on tasks as described above, it can be ensured that each step in the imaging task of displaying images is always being executed by the graphics card. Even if a graphics card malfunctions, the ultrasound equipment can still have the ability to perform external imaging, thus improving the stability of the ultrasound equipment.

[0041] In addition, this application also provides a graphics card task switching device, an ultrasonic device, and a computer-readable storage medium, which also have the above-mentioned beneficial effects. Attached Figure Description

[0045] Figure 3 This is a schematic diagram of the structure of an ultrasonic device provided in an embodiment of this application. Detailed Implementation

[0046] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0047] In one embodiment, the graphics card task switching method provided in this application can be applied to an ultrasound device. The ultrasound device can be configured with a GPGPU and implement graphics card task switching based on the GPGPU. Here, GPGPU stands for General-purpose computing on graphics processing units, a type of computer chip that typically appears in the form of a graphics card. The ultrasound device can obtain and display the corresponding ultrasound images based on the task execution status of the graphics card.

[0048] Please refer to Figure 1 , Figure 1 This is a flowchart of a graphics card task switching method provided in an embodiment of this application.

[0049] The method includes:

[0050] S101: Determine the candidate order among at least two graphics cards in the ultrasound device according to the preset configuration.

[0051] It should be noted that this method is applied to ultrasound equipment. In this application, the ultrasound equipment has at least two graphics cards, which can be of the same or different types. The types of graphics cards can include discrete graphics cards and integrated graphics cards, etc. The hardware parameters and computing power of each graphics card can be the same or different.

[0052] Understandably, the final step in the ultrasound imaging process is the display task, which should be performed by a graphics card, referred to as the primary graphics card. The primary graphics card can be pre-specified, for example, through a preset configuration; or it can be selected according to a selection rule, the specific content of which is not limited, such as random selection. In addition, other graphics cards can perform steps other than the display step; these graphics cards can be referred to as secondary graphics cards. The tasks performed by the primary and secondary graphics cards can be completely different; for example, the primary graphics card may only perform the display task, while all other tasks are performed by the secondary graphics card. Alternatively, the tasks performed by the primary and secondary graphics cards can be partially different; for example, both the primary and secondary graphics cards may perform data acquisition and calculation tasks, but the secondary graphics card does not perform the display task, while the primary graphics card does.

[0053] The preset configuration refers to the settings for the tasks performed by each graphics card in the ultrasound equipment during operation, as well as the relationships between them. Its specific form and content are not limited and can be configured as needed. The relationship between the graphics cards is a candidate order, specifically a directional chain sequence. The nodes in the candidate order are the individual graphics cards, and the direction specifies the preceding and following order relationships between them. By determining the candidate order, if a graphics card malfunctions, another graphics card can be identified to take over the task according to this order, ensuring that the malfunction of a graphics card does not cause the ultrasound equipment to lose its imaging capability.

[0054] Understandably, since ultrasound equipment has at least two graphics cards, and under normal circumstances, all graphics cards are activated and work in parallel during ultrasound equipment operation, the graphics cards need to be initialized during the startup process. Therefore, the following steps may also be included:

[0055] Step 11: If the ultrasound device is detected to be activated, at least two initialization threads are constructed; the number of initialization threads is greater than or equal to the number of graphics cards.

[0056] Step 12: Initialize the corresponding graphics cards in parallel using each initialization thread.

[0057] To reduce the time required for graphics card initialization, this application constructs at least two initialization threads after detecting the start of the ultrasound device, with the number of initialization threads exceeding the number of graphics cards. Each initialization thread works in parallel, initializing its respective graphics card to minimize the time required for graphics card initialization and thus improve the startup speed of the ultrasound device. Preferably, in one embodiment, the number of initialization threads is the same as the number of graphics cards, forming a one-to-one correspondence, maximizing the startup speed of the ultrasound device.

[0058] S102: Based on the preset configuration, determine the task corresponding to each graphics card for processing ultrasonic display information, and use each graphics card to execute the corresponding task.

[0059] Ultrasonic display information refers to the raw ultrasound data used for ultrasound imaging, or intermediate data or image data obtained after processing the raw ultrasound data. Different tasks require different processing methods and the types of ultrasound display information being processed. It should be noted that this embodiment does not limit the specific content of the task corresponding to each graphics card. In one implementation, during external imaging, the entire imaging process may include steps such as data acquisition, preprocessing, calculation, and display (the steps of the imaging process may be simpler or more complex depending on the specific situation), and each step can be assigned as a separate subtask to the graphics card. The preset configuration also specifies the tasks performed by each graphics card; therefore, according to the preset configuration, corresponding tasks can be assigned to each graphics card, and the tasks can be executed by the graphics card after the task assignment is completed. It should be noted that the tasks performed by any two graphics cards can be completely different, only partially the same, or completely identical (for example, the tasks performed by two second graphics cards may be completely identical). According to the preset configuration, a suitable task assignment method can be selected as needed. However, it is understood that the task combination of all graphics cards should be able to include the complete process of ultrasound equipment imaging in order to support the ultrasound equipment in achieving the function of external imaging.

[0060] In one implementation, each graphics card performs a completely different task; that is, all graphics cards cooperate to complete the imaging function. Specifically, the task of processing ultrasound display information includes the ultrasound image display task. In this case, the process of determining the task corresponding to each graphics card according to a preset configuration may include the following steps:

[0061] Step 21: If the preset configuration is task splitting configuration, then determine the several sub-tasks obtained after splitting the ultrasound image display task based on the task splitting configuration.

[0062] Step 22: Assign several subtasks to several different graphics cards.

[0063] Task splitting configuration refers to the configuration where the ultrasound image display task is broken down into subtasks and assigned to different graphics cards for execution. The specific splitting and assignment methods are not limited. An ultrasound image display task refers to the task of processing ultrasound display information when an ultrasound device displays images. This includes multiple subtasks, the type and number of which vary depending on the splitting method. For example, an ultrasound image display task can be split into two subtasks: calculation and display, or into three subtasks: signal preprocessing, data calculation, and display. After splitting, each subtask is assigned to a different graphics card for execution. This method maximizes the utilization of each graphics card's computing resources. It should be noted that for displaying a single frame of image, the subtasks are executed sequentially to complete the image display. That is, since the execution of each subtask in the ultrasound image display task requires the result of the previous subtask, the subtasks needed to be executed sequentially when displaying a particular frame of image until the display subtask is completed. For multi-frame image display, since the imaging process of each image frame is independent and does not affect each other, subtasks belonging to different image frames can be executed in parallel. For example, while one graphics card is executing the calculation subtask corresponding to image A, another graphics card can execute the data preprocessing subtask of image B.

[0064] In another implementation, one graphics card (e.g., the first graphics card) can perform the entire ultrasound image display task, while the other graphics cards perform other subtasks within the ultrasound image display task, excluding the ultrasound image display subtask itself. This allows the first graphics card to take over and complete the entire ultrasound image display task in case of malfunction. Specifically, the task of processing ultrasound display information includes the ultrasound image display task, which contains ultrasound image display subtasks and backup tasks. In this case, the process of determining the tasks corresponding to each graphics card according to a preset configuration may include:

[0065] Step 31: If the preset configuration is task backup configuration, then the ultrasound image display task is determined to be the task corresponding to the first graphics card, and the backup task is determined to be the task corresponding to the second graphics card.

[0066] A backup task refers to the set of subtasks remaining after removing the ultrasound image display subtasks from the ultrasound image display task. A task backup configuration refers to the task configuration of each graphics card in preparation for executing the complete ultrasound image display task. In this case, the first graphics card performs the ultrasound image display task, while the other graphics cards act as backups, performing the same data processing operations as the first graphics card, but omitting the final ultrasound image display step. Therefore, the tasks performed by each of the second graphics cards are backup tasks.

[0067] It should be noted that the backup task in this application, as well as the subtasks corresponding to the ultrasound image display task mentioned above, can be prepared in advance. That is, before external imaging, the ultrasound image display task can be pre-split to obtain the corresponding subtasks; or the ultrasound image display subtasks in the ultrasound image display task can be pre-removed to obtain the backup task. Alternatively, after determining the specific type of the preset configuration, the steps of splitting to obtain subtasks or removing ultrasound image display subtasks can be performed.

[0068] S103: If an anomaly is detected in the target graphics card, the candidate graphics card is determined using the candidate order, and the target task of the target graphics card is executed using the candidate graphics card.

[0069] The target graphics card can be any graphics card. If the target graphics card malfunctions, in order to ensure that its task can continue to be executed and to avoid interfering with the external imaging function of the ultrasound equipment, a candidate graphics card corresponding to the target graphics card is determined using the candidate sequence, and then the candidate graphics card is used to take over the task of the target graphics card, i.e., the target task.

[0070] It is understandable that, since the target graphics card and the candidate graphics card may have overlapping tasks, in order to avoid wasting computing resources, the process of using the candidate graphics card to execute the target task of the target graphics card may specifically include:

[0071] Step 41: Determine whether the first candidate task of the target candidate graphics card has any overlapping parts with the target task.

[0072] Step 42: If there are duplicate parts, remove the duplicate parts from the first candidate task to obtain the second candidate task.

[0073] Step 43: Execute the second candidate task and the target task using the target candidate graphics card.

[0074] The first candidate task refers to the task executed by the target candidate graphics card before executing the target task. When it is determined that the target task needs to be executed, it is first determined whether there is any overlap between the target task and the first candidate task. If the overlap does not need to be executed repeatedly, the overlap in the first candidate task can be removed to obtain the second candidate task. The target candidate graphics card then executes both the second candidate task and the target task.

[0075] Furthermore, after the faulty graphics card that experienced the anomaly is repaired, it should continue to execute the tasks performed before the anomaly occurred, and the tasks performed by the corresponding candidate graphics card should also be restored to their pre-anomaly state. To accurately identify the current candidate graphics card for the restored target faulty graphics card, the candidate status can be recorded in the task switching log each time a candidate is identified. Specifically, after executing the target task of the target graphics card using the target candidate graphics card, the following steps can also be included:

[0076] Step 51: Generate a task switching record based on the target graphics card and the target candidate graphics card.

[0077] The task switching record refers to a record that documents the candidate relationship between the target graphics card and the target candidate graphics card. When a target candidate graphics card malfunctions as the new target graphics card, its candidate relationship with the corresponding new target candidate graphics card also needs to generate a task switching record. The two task switching records can form a chain relationship, ensuring that each malfunctioning graphics card can find the current candidate graphics card executing its task based on the task switching record.

[0078] Based on this, the following steps may also be included:

[0079] Step 52: If the cause of the abnormality of the target abnormal graphics card is fixed, use the task switching record to determine the current candidate graphics card corresponding to the target abnormal graphics card;

[0080] Step 53: Delete the target candidate task from the current candidate task corresponding to the current candidate graphics card; the target candidate task is a task specified by the preset configuration and belongs exclusively to the target abnormal graphics card;

[0081] Step 54: Utilize the target abnormal graphics card to execute the task assigned by the preset configuration.

[0082] The target faulty graphics card refers to any graphics card that malfunctions. Since the task of the target faulty graphics card may switch multiple times, its corresponding candidate graphics card may also malfunction after the target faulty graphics card malfunctions. If the cause of the malfunction is detected to be fixed, the corresponding current candidate graphics card can be determined based on the task switching record.

[0083] After identifying the current candidate graphics card, the target candidate task in its corresponding current candidate task is deleted. The target candidate task corresponds to the portion of the target abnormal graphics card. If the target abnormal graphics card has recovered, there is no need to continue executing the target candidate task using the current candidate graphics card. Furthermore, the task originally assigned to the target abnormal graphics card by the default configuration is executed using the target abnormal graphics card. It should be noted that the target candidate task and the task assigned to the target abnormal graphics card by the default configuration may be the same or different. For example, if the current candidate graphics card is also acting as a candidate graphics card for another abnormal graphics card and has executed its corresponding task, and there is overlap between the tasks of that abnormal graphics card and the target abnormal graphics card, then the current candidate graphics card must still act as a candidate graphics card for that other abnormal graphics card and continue executing the overlapping part of the task; it cannot be deleted from the current candidate task. Therefore, the deleted target candidate task is the task specified by the default configuration that corresponds to the target abnormal graphics card and is unique to the target abnormal graphics card.

[0084] Understandably, there are various reasons that could cause graphics card malfunctions, and different methods are needed to detect and fix different types of malfunctions. Specifically, the process of detecting and fixing the cause of the target malfunctioning graphics card includes:

[0085] Step 61: Determine the anomaly type of the target abnormal graphics card.

[0086] Step 62: If the exception type is software type, then reconstruct the software environment of the target abnormal graphics card, and determine the cause of the exception has been fixed after the software environment reconstruction is completed.

[0087] Step 63: If the exception type is not software type, monitor the exception status and determine that the cause of the exception has been fixed when the exception status returns to normal.

[0088] Here, "software type" refers to the type of graphics card malfunction caused by abnormal operation of the graphics card software. If the malfunction type is software-related, it needs to be repaired from a software perspective, i.e., the software environment of the target malfunctioning graphics card needs to be reconstructed. After the software environment is reconstructed and returned to a normal state, the graphics card malfunction caused by the software environment abnormality is repaired. Therefore, after the software environment reconstruction is completed, it is determined that the cause of the malfunction has been repaired. This embodiment does not limit the specific method of software reconstruction. For example, a watchdog program can be set up. After the graphics card disconnects due to software factors, the watchdog program is automatically triggered after detecting the malfunction type, thereby repairing the software environment of the disconnected graphics card and notifying the ultrasonic equipment after the repair is completed.

[0089] If the exception type is not software-related, it indicates that the graphics card malfunction is caused by other reasons. In this case, the cause of the malfunction cannot be directly repaired; instead, it is necessary to wait for the cause of the malfunction to be resolved through other means. For example, if an unstable power supply voltage causes the graphics card malfunction, the voltage cannot be directly adjusted. In this situation, the abnormal status can be monitored. An abnormal status refers to a state that is not in a valid state due to an abnormal cause; for example, this could be the power supply voltage status of the graphics card. If the abnormal status returns to a normal state (i.e., a valid state), then it can be determined that the cause of the malfunction has been resolved.

[0090] For example, in one specific implementation, the ultrasound device has two graphics cards: graphics card A is a discrete graphics card, and graphics card B is an integrated graphics card. Using OpenCL technology, both graphics cards A and B are used simultaneously for computational tasks other than the display portion of the ultrasound image display. The computational results from both are selected for display, i.e., one graphics card is designated as the primary graphics card. For instance, when both graphics cards A and B are working normally, graphics card A is used as the primary graphics card for display and computation. When graphics card A malfunctions, the display and computation process switches to graphics card B.

[0091] Specifically, in one implementation, if graphics card A and graphics card B perform different tasks, they are used to execute different sub-tasks within the ultrasound image display task. For example, graphics card A executes the ultrasound image display sub-task and the calculation sub-task, while graphics card B executes the data acquisition sub-task and the data preprocessing sub-task. When graphics card A malfunctions, graphics card B will take over and continue executing the ultrasound image display sub-task and the calculation sub-task, enabling the ultrasound equipment to continue providing imaging services.

[0092] In another implementation, graphics card A performs the complete ultrasound image display task, while graphics card B performs the corresponding backup task. When graphics card A malfunctions, graphics card B processes the same data as graphics card A and uses the same data processing method. Therefore, after completing its data processing, graphics card B performs the ultrasound image display sub-task that graphics card A cannot perform, taking over the image display operation and continuing to provide imaging services.

[0093] Therefore, since the data submitted for calculation and display to both graphics cards A and B is identical each time they are working normally, there will be no system crashes or black screens during switching. Only acceptable phenomena such as a decrease in ultrasound frame rate due to differences in hardware parameters and computing power between graphics cards A and B will occur, but the ultrasound equipment will still be able to provide images.

[0094] The graphics card task switching method provided in this application embodiment includes an ultrasound device with at least two graphics cards, each working simultaneously. In the imaging task, display is the final step. Based on a preset configuration, one graphics card can be selected as the first graphics card to perform the display process in the imaging task. The preset configuration sets a replacement order among the graphics cards. By determining the replacement order, a replacement graphics card can be identified to take over the task when a graphics card malfunctions. For example, if the first graphics card malfunctions, the task it performs for image display will be taken over by the replacement graphics card. After assigning tasks to each graphics card, it executes the corresponding task. When the target graphics card malfunctions, to avoid affecting the imaging work of the ultrasound device, a target replacement graphics card is determined and takes over the target task originally performed by the target graphics card. Through the dynamic task switching of computing resources (i.e., graphics cards) described above, it can be ensured that there is always a graphics card performing each step in the imaging task of displaying images externally. Even if a graphics card malfunctions, the ultrasound device can still maintain its imaging capability, improving the stability of the ultrasound device.
