Embodiment Construction

[0049] The technical solutions in the present invention are clearly and completely described below in conjunction with the embodiments and the accompanying drawings. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0050] After research, it is found that the cooperative state estimation algorithm based on multi-sensor network has two implementation methods: centralized framework (Centralized Framework, CF) and distributed framework (Distributed Framework, DF). Among them, the centralized architecture consists of an information fusion center and multiple sensors, and the information fusion center and each sensor need to establish communication. While this provides optimal estimation, it imposes limitations on the application since the information fusion center needs to bear all the computational load while establishi...

Abstract

The invention relates to the technical field of distributed architecture, in particular to a method and device for acquiring a target state based on the distributed architecture and a storage medium. According to the invention, each node body in a distributed architecture is adopted to obtain the state of a target object, then the adjacent node bodies of each node body are combined to carry out inverse covariance cross iterative operation, and finally each node body obtains fused target state data. The distributed architecture increases the robustness of the whole system and reduces the demand for communication bandwidth. According to the invention, the node set is adopted to carry out iterative operation on the target state data obtained by each node body, so that the target state data obtained by each node body can be diffused to a network in which the whole distributed architecture is located, thereby improving the precision of the target state data obtained through the distributed architecture. And meanwhile, a consistent fusion result can be given during each iteration of the adopted iterative algorithm, so that the finally obtained target state data is close to a real state parameter.

Description

technical field [0001] The present invention relates to the technical field of distributed architecture, in particular to a method, device and storage medium for acquiring a target state based on a distributed architecture. Background technique [0002] The collaborative state estimation algorithm based on multi-sensor network has two implementations: Centralized Framework (CF) and Distributed Framework (DF). Among them, the centralized architecture consists of an information fusion center and multiple sensors, and the information fusion center and each sensor need to establish communication. While this provides optimal estimation, it imposes limitations on the application since the information fusion center needs to bear all the computational load while establishing and maintaining direct communication with each node in the sensor network. In addition, the destruction of the information fusion center in the centralized architecture will cause the entire system to collapse;...
