Description

Technical Field

[0001] The present invention relates to the technical field of data processing, and in particular to a pathological specimen auxiliary diagnosis system based on multi-thread control and task scheduling. Background Art

[0002] At present, in the field of pathology, with the development of medical technology and the increasing number of pathological samples, pathological diagnosis has become more arduous and complicated. Therefore, auxiliary diagnosis systems have gradually played an important role in digital pathology.

[0003] However, traditional pathology diagnosis often relies on pathologists to manually analyze whole slide images (WSI). This method is time-consuming and labor-intensive. With the increasing number of cases and the shortage of pathologists, diagnostic efficiency is difficult to meet clinical needs. Moreover, a single diagnostic process usually requires analyzing multiple images and massive amounts of data. Traditional pathology diagnosis methods are currently unable to address these issues, significantly reducing the efficiency of pathology diagnosis.

[0004] Therefore, in order to overcome the above-mentioned defects, the present invention provides a pathological specimen auxiliary diagnosis system based on multi-thread control and task scheduling. Summary of the Invention

[0005] The present invention provides a pathology specimen auxiliary diagnosis system based on multi-threaded control and task scheduling, which is used to monitor the task initiation request of the pathology specimen auxiliary diagnosis task, and use distributed locks to judge the running status of the resources required for the task according to the monitoring results, so as to facilitate the determination of whether the current task can be effectively executed according to the running status, and avoid the conflict of different tasks accessing the same resource. Secondly, when the required resources are not locked, the task execution is started and the task queue is scanned regularly, so as to facilitate multi-threaded task scheduling and control of periodic tasks and delayed tasks in the task queue, realize efficient parallel processing of different tasks, and ensure the operating stability of the system. Finally, the lock is released after the execution is completed, so as to facilitate the processing of the pending tasks in the task queue, and ensure the efficiency and effect of the pathology specimen auxiliary diagnosis.

[0006] The present invention provides a pathology specimen auxiliary diagnosis system based on multi-thread control and task scheduling, comprising:

[0007] The distributed lock management module is used to obtain tasks for auxiliary diagnosis of pathological specimens. Based on the task initiation request, it uses distributed locks to determine the running status of the resources required for the task. If the required resources are not locked, it allocates locks and starts the task execution.

[0008] The scheduled task scheduling module is used to periodically scan the task queue based on the startup results, and assign periodic tasks and delayed tasks in the task queue to the thread pool based on the scanning results;

When a task needs to be executed, a thread is taken out of the thread pool to execute the task. After the task is completed, the thread is not destroyed, but returns to the thread pool to wait for the next task. This can avoid the overhead caused by frequent creation and destruction of threads, improve system performance and resource utilization, and the thread pool can effectively manage and schedule threads, such as controlling the number of threads, setting task queues, etc., to achieve more efficient concurrent processing.

[0076] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0077] Example 1:

[0078] This embodiment provides a pathology specimen auxiliary diagnosis system based on multi-thread control and task scheduling, such as Figure 1 Shown, including:

[0079] The distributed lock management module is used to obtain tasks for auxiliary diagnosis of pathological specimens. Based on the task initiation request, it uses distributed locks to determine the running status of the resources required for the task. If the required resources are not locked, it allocates locks and starts the task execution.

[0080] The scheduled task scheduling module is used to periodically scan the task queue based on the startup results, and assign periodic tasks and delayed tasks in the task queue to the thread pool based on the scanning results;

[0081] A multi-threaded task execution module is used to perform multi-threaded task scheduling and control on periodic tasks and delayed tasks according to a priority mechanism based on the allocation result, and perform data processing on the periodic tasks and delayed tasks based on the multi-threaded task scheduling and control result;

[0082] The loop operation management module is used to release the lock after the execution is completed, and notify the idle thread to continue processing the pending tasks in the task queue based on the release result.

[0083] In this embodiment, the principle diagram of the pathological specimen auxiliary diagnosis system based on multi-threaded control and task scheduling is as follows: Figure 2 shown.

[0084] In this embodiment, the thread pool is a form of multi-threaded processing. A certain number of threads are created in advance and placed in a pool for management. When a task needs to be executed, a thread is taken out of the thread pool to execute the task. After the task is completed, the thread is not destroyed, but returns to the thread pool to wait for the next task. This can avoid the overhead caused by frequent creation and destruction of threads, improve system performance and resource utilization, and the thread pool can effectively manage and schedule threads, such as controlling the number of threads, setting task queues, etc., to achieve more efficient concurrent processing.

[0085] In this embodiment, the distributed lock refers to the Redis distributed lock. Redis is used as the distributed lock management component, and the mutual exclusion mechanism is implemented through the SETNX and EXPIRE commands to ensure that only one thread or node can access or operate shared resources at the same time. At the same time, the RedLock algorithm is used to enhance the reliability of the lock and prevent the lock from failing due to network partitions or process abnormalities.

[0086] In this embodiment, the resources required for the task refer to the data resources needed when performing the corresponding pathological specimen auxiliary diagnosis task.

[0087] In this embodiment, the running status refers to whether the required resource is currently being accessed or is in an idle state.

[0088] In this embodiment, the required resources are not locked, which means that the resources required for the pathological specimen auxiliary diagnosis task are not accessed, that is, there is no thread calling the currently required resources.

[0089] In this embodiment, allocating a lock means allocating the required resource to the current pathology specimen auxiliary diagnosis task when the required resource is not locked, that is, locking the required resource, thereby ensuring execution of the current pathology specimen auxiliary diagnosis task.

[0090] In this embodiment, the task queue contains multiple tasks to be processed.

[0091] In this embodiment, periodic tasks and delayed tasks refer to classifying the attributes of tasks in the task queue into two categories, namely periodic tasks and delayed tasks, wherein periodic tasks can be tasks such as data synchronization and resource cleaning related to auxiliary diagnosis of pathological specimens, and delayed tasks can be asynchronous data processing. Specifically, in asynchronous data processing, when an operation (such as initiating a network request, performing a long calculation, etc.) is started, the program will not block and wait for the completion of the operation, but will continue to execute other tasks. When the asynchronous operation is completed, the program will be notified in some way (such as callback function, event, etc.) so that the program can perform subsequent processing.

[0092] In this embodiment, the priority mechanism is a mechanism for sorting the processing order of different tasks included in the periodic tasks and the delayed tasks.

[0093] In this embodiment, multi-threaded task scheduling and control refers to the allocation of different threads to the tasks to be processed, and at the same time, the execution order and required threads of different tasks are scheduled and managed according to the actual processing situation during the processing process, in order to ensure that different tasks can be effectively processed at the same time.

[0094] In this embodiment, data processing refers to performing business analysis and corresponding diagnosis assistance on corresponding tasks according to the assigned threads.

[0095] In this embodiment, releasing the lock refers to releasing the resources required by the current task after the current task is completed, so as to facilitate the execution of other tasks that require the current resources.

[0096] In this embodiment, the pending tasks refer to other tasks in the task queue that need to be processed.

[0097] The working principle and beneficial effects of the above technical solution are: by monitoring the task initiation request of the pathological specimen auxiliary diagnosis task, and using distributed locks to judge the running status of the resources required for the task based on the monitoring results, it is convenient to determine whether the current task can be effectively executed based on the running status, avoiding conflicts in access to the same resource by different tasks; secondly, when the required resources are not locked, the task execution is started, and the task queue is scanned regularly, so as to facilitate multi-threaded task scheduling and control of periodic tasks and delayed tasks in the task queue, realize efficient parallel processing of different tasks, and ensure the operation stability of the system; finally, the lock is released after the execution is completed, so as to facilitate the processing of pending tasks in the task queue, and ensure the efficiency and effect of pathological specimen auxiliary diagnosis.

[0098] Example 2:

[0099] Based on Example 1, this embodiment provides a pathology specimen auxiliary diagnosis system based on multi-thread control and task scheduling, and a distributed lock management module, including:

[0100] a time determination unit, which obtains the allowable task processing time of a single use of the distributed lock based on the management terminal, and determines a timeout time of the distributed lock based on the allowable task processing time;

[0101] The distributed lock configuration unit is used to configure the distributed lock based on the timeout period. At the same time, it obtains the processing strategy after the timeout based on the management terminal, and configures the workflow of the distributed lock based on the processing strategy to obtain the final distributed lock.

[0102] In this embodiment, the processing strategy is set in advance, and the distributed lock may be automatically released after a timeout so that other nodes can acquire it.

[0103] In this embodiment, the timeout configuration of the distributed lock based on the timeout period refers to the maximum threshold of the processing task duration. When the maximum threshold is exceeded, the distributed lock is automatically released based on the processing strategy.

[0104] In this embodiment, configuring the workflow of the distributed lock based on the processing strategy refers to configuring the processing strategy into a mechanism that can be automatically executed, that is, determining the operation mode of the distributed lock in different situations according to specific rules and methods.

[0105] The working principle and beneficial effects of the above technical solution are: by obtaining the allowable task processing time when the distributed lock is used once, the timeout time of the distributed lock is effectively determined, and then the distributed lock is configured with a timeout based on the timeout time and the workflow of the distributed lock is configured based on the processing strategy, thereby effectively realizing the acquisition of the distributed lock, enhancing the precise control and management of the use time of the distributed lock, ensuring that resources are used within a reasonable time, and avoiding unlimited occupation.

[0106] Example 3:

[0107] Based on Example 1, this embodiment provides a pathology specimen auxiliary diagnosis system based on multi-thread control and task scheduling, such as Figure 3 As shown, the distributed lock management module includes:

[0108] A request monitoring unit is configured to establish a monitoring mechanism based on system operation requirements, and to monitor the data status of the request access interface in real time based on the monitoring mechanism, thereby obtaining a state sequence of the request access interface. When there is a sudden change in the data status at adjacent moments in the state sequence, it is determined that a task initiation request has been received.

[0109] Request parsing unit, used to:

[0110] Parse the received task initiation request and determine the target resources required for the current task based on the parsing results;

[0111] Traverse the access data of the target resource and determine the current access status of the target resource based on the traversal result. If no object is accessing the target resource, determine that the required resource is not locked.

[0112] The task initiation unit is used to initiate a request for allocation lock for the current task based on the determination result, lock the required resources, and call the required resources based on the locking result to perform a process response to the task initiation request.

[0113] In this embodiment, the monitoring mechanism refers to a tool that is determined according to pre-set system operation requirements and is used to monitor the data status of the access request interface.

[0114] In this embodiment, the data status of the access request interface may be a working status or a busy status of the access request interface.

[0115] In this embodiment, the state sequence of requesting access to the interface refers to a set of sequences obtained by recording the state of requesting access to the interface in real time according to a preset time interval.

[0116] The working principle and beneficial effects of the above technical solution are: through the constructed monitoring mechanism, the data status of the request access interface is monitored in real time, and when a sudden change in the data status is found at adjacent moments, it is determined that there is a task initiation request; the task initiation request is parsed to find the required target resource, and then the current access status of the target resource is determined by traversing the access data to determine whether it is locked; lock allocation and resource locking are performed when it is determined that the resource is not locked, and then the locked resource is used to respond to the task initiation request, thereby realizing the response to the process, being able to monitor the task initiation request in real time and accurately, and process it in time, thereby improving the responsiveness and real-time performance of the system; effectively managing resource access in a distributed environment to ensure the stable operation of the system and data consistency.

[0117] Example 4:

[0118] Based on Example 3, this embodiment provides a pathology specimen auxiliary diagnosis system based on multi-thread control and task scheduling, wherein the request parsing unit includes:

[0119] The result retrieval subunit is used to obtain the current access status of the target resource determined based on the traversal result, and when there is object access to the target resource, determine that the required resource has been locked;

[0120] A processing subunit, configured to:

[0121] Extracting the time attribute of the task initiation request based on the determination result, and determining the specific timestamp corresponding to the task initiation request based on the time attribute;

[0122] Obtain the waiting queue for the required resources based on the background management terminal, and sort the task initiation requests based on the specific timestamp;

[0123] Based on the sorting results, each task initiation request is sorted and waited in the waiting queue. At the same time, based on the configuration parameters of the distributed lock, the processing time of all task initiation requests before each task initiation request is evaluated, and based on the evaluation results, the response time of each task initiation request is determined in turn, and the response time of each task initiation request is marked based on the determination result.

[0124] In this embodiment, the specific timestamp indicates the starting time point corresponding to the specific task initiation request.

[0125] The working principle and beneficial effects of the above technical solution are as follows: by determining the access status of the target resource, it is effectively determined whether the resource is locked. When the resource is locked, the time attribute of the task initiation request is extracted and the specific timestamp is determined. Then, based on the waiting queue obtained in the background, the task initiation requests are sorted according to the timestamp. At the same time, the processing time of all predecessor task initiation requests is evaluated according to the configuration parameters of the distributed lock, and the response time of each task initiation request is determined and marked. It can finely handle task initiation requests under resource locking conditions, improve the orderliness and fairness of the system through orderly queuing and time management, effectively avoid confusion and errors caused by resource competition, and ensure that tasks are processed in a reasonable order and time.

[0126] Example 5:

[0127] Based on Example 1, this embodiment provides a pathology specimen auxiliary diagnosis system based on multi-threaded control and task scheduling, and a scheduled task scheduling module, including:

[0128] an interval determination unit, configured to determine a scanning frequency for the task queue based on management requirements, and determine a time interval for performing a single scan of the task queue based on the scanning frequency;

[0129] Scanning unit for:

[0130] Adapting a time trigger parameter of a preset trigger based on a time interval, and periodically generating a trigger instruction based on the time trigger parameter adaptation result;

[0131] The task queue is scanned periodically based on the trigger instruction, and tasks to be processed in the task queue are identified based on the periodic scanning result, and periodic tasks and delayed tasks are obtained based on the identification result;

[0132] The task allocation unit is used to allocate the identified periodic tasks and delayed tasks to the thread pool for execution.

[0133] In this embodiment, the management requirement is set in advance and is used to represent the scanning frequency of the task queue.

[0134] In this embodiment, the preset trigger is a tool or device that is set in advance and is used to generate a trigger signal.

[0135] In this embodiment, time trigger parameter adaptation refers to configuring parameters of a preset trigger according to a determined time interval, in order to ensure that the preset trigger can generate a periodic trigger signal.

[0136] In this embodiment, periodically generating a trigger instruction refers to controlling the generation of an instruction by a preset trigger according to the adaptation result of the time trigger parameter, for the purpose of periodically scanning the task queue.

[0137] The working principle and beneficial effects of the above technical solution are: by parsing the management requirements, the scanning frequency of the task queue is determined, and the time interval of a single scan is locked. Secondly, the time trigger parameters of the preset trigger are adapted according to the determined time interval, so as to periodically generate trigger instructions. Finally, the task queue is scanned regularly according to the periodically generated trigger instructions, and periodic tasks and delayed tasks are effectively identified. The identified periodic tasks and delayed tasks are assigned to the thread pool for execution, ensuring the efficiency of the execution of pathological specimen auxiliary diagnosis tasks.

[0141] Identify unit subunits for:

[0142] Based on the periodic task index and the delayed task index, each task in the task queue is traversed to obtain the task attributes of each task, and the task attributes of each task are matched with the periodic task index and the delayed task index respectively;

[0143] Based on the matching results, periodic tasks and delayed tasks are obtained, and the periodic tasks and delayed tasks are classified and integrated.

[0144] In this embodiment, the pathology specimen auxiliary diagnosis system is known in advance and is used to characterize all knowledge and parameters related to pathology specimen auxiliary diagnosis.

[0145] In this embodiment, the periodic task indicator refers to an indicator parameter that can characterize the current task as a periodic task, such as a data synchronization indicator and a data cleaning indicator, both of which are tasks that need to be performed periodically.

[0146] In this embodiment, the delay task indicator refers to an indicator parameter that can characterize the current task as a delay task, for example, it can be a processing time parameter. When the processing time parameter exceeds a certain threshold, it is a delay task.

[0147] In this embodiment, the task attributes refer to parameter information that can characterize the type or requirements of each task.

[0148] The working principle and beneficial effects of the above technical solution are: by analyzing the auxiliary diagnosis system of the acquired pathological specimens, the periodic task indicators and delayed task indicators are effectively determined, providing a reference basis for task identification; secondly, according to the obtained periodic task indicators and delayed task indicators, each task in the task queue is matched and analyzed to achieve effective identification and distinction of periodic tasks and delayed tasks, thereby providing convenience and guarantee for multi-threaded allocation and task scheduling of periodic tasks and delayed tasks.

[0155] Multi-threaded task scheduling and control unit, used for:

[0156] Based on the priority sorting results, periodic tasks are set as main thread tasks, and delayed tasks are set as background tasks. Threads are then allocated to each main thread task and background task in turn based on the setting results and execution order.
