Technical Field

[0001] The present invention relates to the technical field of electronic equipment resource scheduling based on a resource pool architecture, and in particular to a resource management device and method for a phased array system based on a resource pool architecture. Background Art

[0002] Resource pool technology is a concept widely used in many fields. Its main goal is to achieve centralized management and dynamic allocation of resources, thereby improving resource utilization efficiency, flexibility and scalability. Integrating scattered resources into a unified resource pool can facilitate centralized management and monitoring, and can be flexibly and efficiently scheduled according to task needs.

[0003] Electronic equipment systems based on large phased arrays generally contain a considerable number of hardware modules and extensions to complete various functions from space signal transmission and reception to data information processing. For example, phased array antenna systems are used for space signal transmission and reception, general signal processing platforms are used for baseband signal processing, and computer platforms are used for data processing and various display monitoring. In order to better schedule and manage various resources of the system and achieve rapid response to tasks, various hardware resources can be classified and virtualized. Through virtualization, hardware resources are transformed into various functional modules, which realizes the decoupling of tasks from the underlying hardware, and then the virtualized functional modules are managed and monitored in a resource pool. Transforming the hardware resources of the electronic equipment system into multiple resource pools composed of various functional modules can greatly improve the system's integration, task reliability, and flexibility of resource use. For example, the Chinese invention patent application with publication number CN112700172A, "A Flexible Design Method for a Wideband Passive Phased Array Resource Scheduling Framework," counts the resources that a passive phased array radar may have, virtualizes each resource, and puts it into a virtual resource pool. It then modifies the resource data in the virtual resource pool accordingly based on different passive phased array radar design requirements.

The beam resource pool management module schedules the task. p Required transmit beam TBeam i and receive beam RBeam j To lock, the baseband resource pool management module schedules the task p Required Mods k and demodulator DeMod m To lock the task, the computing resource pool management module will schedule the task p Required virtual machine VirPC n Lock and build the task plan Task p The desired transmit beam set SetTBeam p , receive beam set SetRBeam p , Modulator set SetMod p , demodulator set SetDeMod p , computing resource requirement set SetVirPC p The comprehensive operation management module then plans the task according to the task pBased on the link interconnection and backup requirements, an interconnection matrix of the above five sets is constructed to achieve task and resource matching. The elements in the interconnection matrix represent the interconnection relationship between resource pools. When the element in the interconnection matrix is ​​1, it means that the resource elements in the resource pool are interconnected, data / information interaction can be achieved, and task planning can be executed. When the element in the interconnection matrix is ​​0, it means that the interconnection line / network between the resource elements in the resource pool is interrupted, data / information interaction cannot be achieved, and task execution fails. Information interaction between multiple virtualized resource pools is achieved.

[0100] The beam resource pool management module can schedule and manage the beam resource pool, including: a transmit beam resource pool beam synthesis device and a receive beam resource pool beam synthesis device, wherein the transmit beam resource pool beam synthesis device includes:

[0101] The transmit beam resource pool management module is used to periodically send the beam pointing and required beam EIRP of the managed transmit beam: EIRP is the equivalent isotropic radiated power (Equivalent Isotropic Radiated Power);

[0102] The array resource management module is used to adaptively schedule the subarrays according to the beam pointing of each transmit beam and the required beam EIRP. When the angle between the subarray normal pointing and the beam pointing is less than or equal to the set angle and the sum of the subarray EIRP is greater than or equal to the required beam EIRP, the transmit beam in the specified direction is synthesized; the scheduled subarrays constitute the subarray set S i (t), the calculation formula of the sum of sub-array EIRP is:

[0103] G k is the set of sub-matrices S i The normal gain of the kth sub-matrix in (t), P k is the set of sub-matrices S i The transmission power of the kth subarray in (t), θ k (t) is the sub-matrix set S i The angle between the normal of the kth subarray and the beam direction in (t), K is the subarray set S i (t) The total number of neutron arrays, 1≤k≤K.

[0104] The transmit beam resource pool management module manages I(t) transmit beams at time t, and the i-th transmit beam is denoted as TBeam i , i∈[1,I], I represents the transmit beam TBeam i The total number of transmit beams TBeam is periodically updated by the transmit beam resource pool management module according to the beam update period. i The beam pointing and the required beam EIRP are sent to the array resource management module, and the array resource management module divides the M planar sub-arrays on the array into an idle sub-array set S idle (t) and the set of working subarrays S busy (t), the surface used to synthesize the transmit beam TBeam i The plane sub-matrix of i (t), different transmit beams do not share a plane subarray, the working subarray set S busy (t) = S 1 (t)∪S 2 (t)∪...∪S I(t) (t).

[0105] See also Figure 3 and 4 The process of adaptively scheduling the sub-arrays by the array resource management module according to the beam pointing of each transmit beam and the required beam EIRP includes:

[0106] Step 1: At time t+Δt, Δt represents the transmit beam update period, the array resource management module determines the transmit beam TBeam iIs the task finished? If so, set the subarray set S i (t) The sub-array is released. If it is not finished, the idle sub-array set S is maintained. idle (t) and the set of working subarrays S busy (t) unchanged;

[0107] Step 2: Select the idle subarray set S idle (t) extract K continuous distribution sub-matrices A k The sub-array set S i (t+Δt), update the idle subarray set S iale (t+Δt) and the working subarray set S busy (t+Δt);

[0108] Step 3: Determine subarray A k The normal direction and the beam pointing direction of the transmitted beam Is the angle between them less than or equal to the set angle? If so, go directly to step 4. If not, change subarray A k From the sub-matrix set S i After deleting (t+Δt), proceed to step 4;

[0109] Step 4: Determine the subarray set S i Is the sum of the subarray EIRP greater than or equal to the beam EIRP at (t+Δt)? i (t+Δt), if so, based on the subarray set S i (t+Δt) synthesizes the transmit beam; if not, select the idle subarray set S idle (t+Δt) and the subarray set S i (t+Δt) adjacent sub-matrix A p , when subarray A p Normal and beam pointing The angle between them is less than or equal to the set angle, and the subarray A p Put the subarray set S i (t+Δt), get the updated sub-array set S i (t+Δt), repeat this step until the updated sub-array set S is satisfied i The sum of the subarray EIRP at (t+Δt) is greater than or equal to the beam EIRP i (t+Δt), based on the updated sub-array set S i (t+Δt) synthesized transmit beam.

[0110] In step 1, determine the transmit beam TBeam i Whether the mission is completed is determined by judging the beam EIRP i (t+Δt) is equal to 0, 1≤i≤I(t+Δt), if EIRP i(t+Δt)=0, determine the transmit beam TBeam i After the task is completed, the array resource management module sets the subarray set S i (t) is released, that is, S idle (t+Δt)=S idle (t)∪S i (t), and reduce the number of managed transmit beams by I(t+Δt)-I(t); if EIRP i (t+Δt)>0, determine the transmit beam TBeam i The task is not completed, and the array resource management module maintains the idle sub-array set S idle (t) and the set of working subarrays S busy (t) remains unchanged.

[0111] In step 2, update the idle subarray set S idle (t+Δt) and the working subarray set S busy (t+Δt) means: from the idle sub-array set S idle (t) Delete the subarray set S i (t+Δt) to get the idle subarray set S idle (t+Δt), and in the working sub-array set S busy (t) Add subarray set S i (t+Δt) to get the working sub-array set S busy (t+Δt).

[0112] The setting angle of the present invention is 60°, and by judging the subarray A k Normal and beam pointing Is the angle between them less than or equal to 60°? If it is less than or equal to 60°, it means that subarray A k The efficiency of participating in beam synthesis is greater than half and has not been attenuated to half. If it is greater than 60°, it means that the subarray A k The angle between the normal direction of the composite beam and the direction of the composite beam is too large, so the subarray A k Only half of the power can be contributed to the total beam, and the efficiency is only 50%. Therefore, it does not participate in the transmit beam synthesis. k Normal and beam pointing By adjusting the angle between the two sub-arrays, the sub-array with larger power contribution is selected to participate in the transmit beam synthesis, which can improve the working efficiency of the system.

[0113] In step 3, determine subarray A k The normal direction and the beam pointing direction of the transmitted beam The process of determining whether the angle between them is less than or equal to the set angle includes:

[0117] The transmit beam resource pool beam synthesis device is based on the antenna array of the subarray collection (rather than processing each antenna unit independently). According to the different beam pointing directions, different subarrays are scheduled to participate in beam synthesis, and the minimum-scale subarray is scheduled to participate in beam synthesis according to the needs of the task, rather than all subarrays participating in the synthesis, so as to improve the working efficiency of the array surface; under the requirement of the beam equivalent isotropic radiated power EIRP, the synthesized beam in the specified direction is completed at the minimum cost (minimum-scale array surface), so as to minimize the power consumption of the system. During the task execution process, by judging the angle between the normal pointing of the subarray and the pointing required by the synthesized beam, and the EIRP of the subarray itself (composed of subarray gain (dB) + subarray power (dBW)), the subarray resources are adaptively scheduled, and the synthesis of the transmit beam is completed with the minimum-scale array surface, which can realize efficient scheduling of subarray resources for large multi-faceted phased arrays or large conformal phased array systems based on subarray splicing, make full use of the flexibility of multi-faceted or conformal phased array systems, synthesize beams according to the transmission power requirements, and achieve optimal power efficiency.
