Description

Technical Field

[0001] This invention belongs to the field of task planning, and specifically relates to a strategy-based method for online automatic adjustment of usage frequency. Background Technology

[0002] The electromagnetic spectrum, as a vital medium for information transmission, has greatly facilitated human life. However, with the rapid development of information technology, problems such as the interaction and mutual influence between frequency-using devices have become increasingly serious, exceeding the scope of traditional frequency coordination and management. This has led to phenomena such as performance degradation or functional failure of frequency-using devices. Therefore, there is an urgent need for more efficient and intelligent planning and management of electromagnetic resources, enabling the overall system to achieve frequency coordination under specific frequency usage strategies. This will allow for effective resource utilization, prevention of electromagnetic self-interference, elimination of intentional and unintentional interference, and rapid response to new demands and time-sensitive tasks.

[0003] Currently, frequency coordination management methods among frequency-using devices are mainly divided into centralized planning and distributed planning. Centralized planning can uniformly plan the frequency usage of all frequency-using devices globally, resulting in user plans that meet frequency usage needs. However, joint planning for all frequency-using devices significantly increases system complexity. Distributed planning does not require information on all frequency-using devices globally, effectively reducing system complexity. However, it ignores the interaction between frequency-using devices in different frequency usage areas, which can lead to frequency conflicts in some areas. Summary of the Invention

[0004] This invention proposes a strategy-based online automatic frequency adjustment method, which can coordinate the business relationships of various frequency-using devices through frequency management strategies and hierarchical frequency planning, and minimize mutual interference between frequency-using devices, thereby providing a scientific and effective real-time frequency plan for the normal operation of the overall system and ensuring the smooth realization of frequency demand.

[0005] The technical solution for implementing this invention is as follows: a strategy-based online automatic frequency usage adjustment method, which divides the overall frequency usage area and unit frequency usage area into coarse-grained frequency usage time through frequency usage management strategies and hierarchical frequency usage planning, then performs fine-grained frequency usage collaborative planning within each unit frequency usage area, and automatically adjusts the strategy based on the performance evaluation results of the task. The specific steps are as follows:

[0006] Step 1: Based on the frequency usage information input by the frequency usage perception system and the frequency usage demand input by the frequency usage business system, select a frequency usage strategy to divide the overall frequency usage area into units and allocate frequency usage resources, and output the frequency usage area division and frequency usage resource allocation of each unit.

[0007] Step 2: Based on the frequency usage area division and frequency resource allocation of each unit output in Step 1, plan the frequency usage time of each unit's frequency usage area, and output the frequency usage time plan of each unit's frequency usage area in the overall frequency usage area.

[0008] Step 3: Based on the frequency usage time planning of each unit frequency usage area output in Step 2, conduct frequency usage coordination planning within each unit frequency usage area, and output the frequency usage plan of each unit frequency usage area in the overall frequency usage area.

[0009] Step 4: Perform task performance evaluation based on the frequency usage plans for each unit's frequency usage area output in Step 3. If the performance evaluation results do not meet the frequency usage requirements, return to Step 1 for strategy adjustment. If the performance evaluation results meet the frequency usage requirements, output the frequency usage plan.

[0010] Compared with the prior art, the significant advantages of this invention are:

[0011] (1) Based on the frequency management strategy, resource allocation is carried out to reduce the complexity of the frequency planning system and improve the response speed of the frequency planning system.

[0012] (2) Decoupling of overall regional frequency demand and unit regional frequency demand is achieved through hierarchical frequency planning. Attached Figure Description

[0018] The strategy-based online automatic frequency usage adjustment method of this invention divides the overall frequency usage area and unit frequency usage area into coarse-grained frequency usage time through frequency usage management strategies and hierarchical frequency usage planning. Then, it performs fine-grained frequency usage collaborative planning within each unit frequency usage area and automatically adjusts the strategy based on the task's performance evaluation results. This method reduces the coupling between frequency-using devices while effectively reducing the complexity and response time of the frequency usage planning system, adaptively providing scientific and effective real-time frequency usage plans.

First, the frequency service system sends frequency requirements to the frequency planning and control center; second, the frequency planning and control center sends frequency management instructions to the frequency sensing system; then, the frequency sensing system sends frequency usage information to the frequency planning and control center; finally, the frequency planning and control center combines the frequency requirements and usage information to generate a real-time frequency usage plan, and sends it to the frequency service system via frequency management instructions.

[0020] Combination Figure 2 A policy-based method for online automatic adjustment of usage frequency includes the following steps:

[0021] Step 1: Based on the frequency usage data input from the frequency usage awareness system and the frequency usage requirements input from the frequency usage service system, select a frequency usage strategy to divide the overall frequency usage area into units and allocate frequency resources, and output the frequency usage area division and resource allocation details for each unit. This mainly includes the following steps:

[0022] Step 1-1: The Frequency Usage Planning and Control Center receives frequency usage requests from the frequency usage business system, including frequency usage area, frequency usage range, frequency usage time, frequency usage items, and frequency usage priority information.

[0023] Steps 1-2: The frequency planning and control center sends frequency management instructions to the frequency sensing system to obtain the frequency usage information of the frequency usage area and its surrounding areas in the frequency usage demand, including frequency usage area, frequency usage range, frequency usage time, frequency usage items and frequency usage priority information.

[0024] Steps 1-3: Based on the current frequency usage demand and situation, the frequency planning and control center divides the overall frequency usage area into unit frequency usage areas and allocates frequency resources according to the frequency usage management strategy (frequency priority, frequency avoidance, frequency sharing, frequency suppression), so as to maximize the coverage of the frequency usage area and frequency range in the frequency usage demand of each unit frequency usage area.

[0025] Step 2: Based on the frequency usage area division and frequency resource allocation of each unit output in Step 1, plan the frequency usage time of each unit's frequency usage area, and output the frequency usage time plan of each unit's frequency usage area in the overall frequency usage area.

[0026] Step 3: Based on the frequency usage time planning for each unit's frequency usage area output in Step 2, perform frequency usage coordination planning within each unit's frequency usage area, and output the frequency usage plan for each unit's frequency usage area in the overall frequency usage area. This mainly includes the following steps:

[0027] Step 3-1: Based on the current frequency usage demand and usage status, the frequency usage planning and control center allocates frequency resources to the frequency usage equipment in each unit's frequency usage area according to the frequency usage matters, and outputs the frequency resource allocation status of each frequency usage equipment.

[0028] Step 3-2: Based on the frequency resource allocation of each frequency-using device, plan the frequency usage time of each frequency-using device and output the frequency usage plan of each frequency-using device in each unit frequency-using area.

[0029] Step 3-3: Combine the frequency usage time planning of each unit frequency usage area in the overall frequency usage area with the frequency usage plan of each frequency usage device in each unit frequency usage area, and output the frequency usage plan of each frequency usage device in the overall frequency usage area.

[0030] Step 4: Based on the frequency usage plans for each unit's frequency usage area output in Step 3, perform a task performance evaluation to determine whether the frequency usage plans meet the frequency usage requirements. If the performance evaluation result does not meet the frequency usage requirements, return to Step 1 for strategy adjustment. If the performance evaluation result meets the frequency usage requirements, output the frequency usage plan. This mainly includes the following steps:

[0031] Step 4-1: Based on the generated frequency usage plan, use a simulation demonstration method to conduct a performance evaluation and observe whether the performance evaluation results meet the current frequency usage requirements.

[0032] Step 4-2: If the performance evaluation result does not meet the current frequency usage requirements, return to Step 1 to regenerate the frequency usage plan, and use the performance evaluation result as the input for strategy adjustment during frequency usage plan generation. If the performance evaluation result meets the current frequency usage requirements, output the frequency usage plan.
