Description

Technical Field

[0001] The present invention mainly relates to the technical field of electronic systems engineering, and particularly to a hierarchical scheduling control method for a multi-sensor system. Background Art

[0002] With the continuous development of digital technology, the technical level of electronic devices has made great progress. However, generally speaking, it still belongs to the development mode of single-function equipment developing independently or simply superimposing multi-functions. With the technological development and function expansion of each single-function equipment, there are overlaps and intersections in capabilities among the originally independent sensor equipments, resulting in a large amount of duplicate construction and fierce competition for spectrum resources. However, due to the lack of hierarchical scheduling control technology for sensor resources, the further development of the functions and performances of electronic equipments has been greatly restricted, and it is weak in the cooperation of various sensors to complete multi-tasks, making it difficult to meet the development needs of intelligent hierarchical scheduling of electronic equipments in the information age.

[0003] By continuously promoting the application of technologies such as cognitive radar, cognitive electronic warfare, and artificial intelligence, strengthening the integrated scheduling and control of radio frequency and optical frequency information, forming a cognitive-based intelligent architecture, automatically sensing the characteristics of targets and environments, combining specific application requirements, online optimizing the system working mode, realizing the best matching of energy distribution, resource allocation, and targets and environments, while reducing the dependence on operators, avoiding the overlapping waste of time, space, frequency, and energy, giving full play to the functions and performances of electronic equipments, adaptively hierarchically scheduling and controlling according to demand changes, and executing different tasks. Summary of the Invention

[0004] The present invention proposes a hierarchical scheduling control method for a multi-sensor system. Aiming at the resource waste caused by the simple superposition of the functions of each sensor equipment, and being weak in the cooperation of various sensors to complete multi-tasks and difficult to meet the requirements of intelligent hierarchical scheduling of electronic equipments in the information age, this method generates a globally optimal scheduling and decision-making scheme that meets the requirements of multi-functions and multi-tasks based on the perception and analysis results of current information, combined with the resource constraints of its own system, and realizes the real-time response to various tasks.

[0005] To achieve the above object, the present invention provides a hierarchical scheduling control method for a multi-sensor system, including the following steps: Step 1: Use a multi-sensor system, where the sensor system includes a hierarchical scheduling control architecture, and the hierarchical scheduling control architecture includes a task layer scheduling module, a function layer scheduling module, and a device layer scheduling module; Step 2: The superior system initiates a task to the multi-sensor system, and the task layer scheduling module divides the task into task instructions related to each function through preliminary decomposition of the task; Step 3: The task layer scheduling module automatically completes the dynamic and real-time optimization and allocation of the multi-sensor system resources according to the changes in the external environment and the resource usage of the multi-sensor system, and further decomposes the preliminarily decomposed task instructions into several function layer scheduling modules in combination with the function classification of the multi-sensor system; Step 4: The function layer scheduling module further breaks down the superior task into the function sequence and timing requirements for specific devices according to the resources required to implement the function and in combination with the device composition of the multi-sensor system. Driven by the device layer scheduling module, it collaboratively completes the superior task according to the decomposed function sequence and timing requirements.

[0006] Further, it further includes Step 5: Automatically feedback the task completion situation and resource usage situation into the hierarchical scheduling control architecture of the multi-sensor system, and further supervise and optimize the task execution situation and resource usage situation.

[0007] Further, in Step 1, the task layer scheduling module is the highest scheduling level of the multi-sensor system, the function layer scheduling module is the intermediate scheduling level of the multi-sensor system, and the device layer scheduling module is the basic scheduling level of the multi-sensor system.

[0008] Beneficial effects: The present invention provides a hierarchical scheduling control method for a multi-sensor system, which can complete the real-time and dynamic allocation of system resources according to the external environment situation and system resource usage situation, decompose the superior task instructions into different tasks according to three levels of task layer scheduling, function layer scheduling and device layer scheduling, then transform them into different function scheduling at the function layer, and finally transform them into the function sequence and timing requirements for each device at the device layer. Innovatively, it solves the resource conflict and waste problems when multiple devices concurrently implement multi-task functions through hierarchical scheduling control technology, and greatly improves the collaborative work, resource utilization and task quick response capabilities of each device in the multi-sensor system.

Embodiment

[0012] A method for hierarchical scheduling control of a multi-sensor system includes the following steps: The present invention has been implemented in a certain ship integrated electronic system, which integrates various functions such as detection and reconnaissance and includes multiple types of sensor devices. Taking this system as an example, the specific implementation and application of the present invention are introduced as follows: (1) The scheduling control receives task instructions or manual intervention commands from the superior system, and according to the external environmental conditions and the system resource usage conditions, completes the real-time and dynamic scheduling of system resources, and gradually transforms the tasks into the function sequences and timing requirements for each device in a hierarchical and classified manner. Its hierarchical architecture mainly includes three categories: task layer scheduling, function layer scheduling, and device layer scheduling. For details, see Figure 2 .

[0013] (2) The task layer scheduling is the highest scheduling level of this system. According to the specific classification of tasks, through the task layer scheduling software, the superior tasks are initially decomposed to the function layer scheduling, and the related work of task management and resource allocation is carried out.

[0014] (3) The function layer scheduling is the intermediate scheduling level of the system. According to the function classification of the superior tasks, through the function layer scheduling software, the hierarchical superior tasks are further decomposed to the device layer scheduling according to the results allocated by the task layer scheduling. Its composition mainly includes detection function management control, reconnaissance function management control, etc.

[0015] (4) The device layer scheduling is the basic scheduling level of the system. According to the device classification of the superior tasks, through the device layer scheduling software, the superior tasks are finally decomposed into the function sequences and timing requirements for each device according to the results allocated by the function layer scheduling. Its composition mainly includes the scheduling control of each device.

[0016] (5) After the hierarchical scheduling control is completed, the completion status of the superior tasks and the resource usage conditions will be automatically fed back to the task management and resource allocation nodes of the task layer scheduling, and further supervise and optimize the task execution status and resource usage conditions, so as to improve the system's resource conflict resolution ability when executing multiple tasks.

[0017] A method for hierarchical scheduling control of a multi-sensor system, as Figure 1 shown, includes the following steps: Step 1: Use a multi-sensor system, where the sensor system includes a hierarchical scheduling control architecture, and the hierarchical scheduling control architecture includes a task layer scheduling module, a function layer scheduling module, and a device layer scheduling module; The task layer scheduling module is the highest scheduling level of the multi-sensor system, the function layer scheduling module is the intermediate scheduling level of the multi-sensor system, and the device layer scheduling module is the basic scheduling level of the multi-sensor system; Step 2: The superior system initiates a task to the multi-sensor system by means of a task instruction or an artificial intervention command. The task layer scheduling module divides the task into task instructions related to each function through preliminary decomposition of the task; Step 3: The task layer scheduling module automatically completes the dynamic and real-time optimization and allocation of the resources of the multi-sensor system according to the external environmental changes and the resource usage of the multi-sensor system, and further decomposes the initially decomposed task instructions into several function layer scheduling modules in combination with the function classification of the multi-sensor system; for example, detection-related instructions can be decomposed by the task layer scheduling module into detection-related functions; Step 4: The function layer scheduling module further breaks down the superior task into the function sequence and timing requirements for specific devices according to the resources required to implement the function and in combination with the device composition of the multi-sensor system. Driven by the device layer scheduling module, it collaboratively completes the superior task according to the decomposed function sequence and timing requirements; Step 5: Automatically feedback the task completion situation and resource usage situation into the hierarchical scheduling control architecture of the multi-sensor system, and further supervise and optimize the task execution situation and resource usage situation.

[0018] The present invention provides a hierarchical scheduling control method for a multi-sensor system, which can complete the real-time and dynamic allocation of system resources according to the external environmental situation and the system resource usage situation, decompose the superior task instructions into different tasks according to three levels of task layer scheduling, function layer scheduling and device layer scheduling, then transform them into different function schedulings at the function layer, and finally transform them into the function sequence and timing requirements for each device at the device layer. It innovatively solves the resource conflict and waste problems when multiple devices concurrently implement multi-task functions through hierarchical scheduling control technology, and greatly improves the collaborative work, resource utilization and task quick response capabilities of each device of the multi-sensor system.

[0019] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
