Embodiment Construction

[0020] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0021] The UWB positioning base station deployment scheme and evaluation method based on the 3D model of the substation, including the 3D model scene of the substation based on 3D laser scanning technology;

[0022] The deployment scheme is as follows:

[0023] 1a) According to the CAD drawings of substations, set the deployment principle of UWB positioning base station. The deployment principle of UWB positioning base station is: UWB positioning base station is installed at a position with fixed supports outside the safe distance of live equipment, and the height range of UWB positioning base station deployment Set it to 1-100 meters, set the spacing to 0.1-50 meters, select as many suitable deployment points as possible, and complete the initial deployment scheme design;

[0024] 1b) According to the initial deployment plan, set m ...

Abstract

The present invention relates to a UWB positioning base station deployment scheme and evaluation method based on a three-dimensional model of a substation. The UWB positioning base station with the most line-of-sight connections with a single target, the greater the number, the better the deployment solution. After repeated tests, the optimal deployment solution was found. With the accurately modeled 3D simulation model of the whole station as the background, the actual deployment results are truly simulated to ensure that the evaluation conclusion is consistent with the actual application effect; the position of the base station can be adjusted arbitrarily in the model, and the number of UWB positioning base stations can be increased or decreased, so that it can be easily changed Deploy the plan to achieve the best effect; collect the connection relationship between the UWB positioning base station and the target object in real time, and accurately display the number of UWB positioning base stations in the line-of-sight to the target object, providing a reliable basis for signal quality evaluation.

Description

technical field [0001] The invention belongs to the technical field of positioning base stations, and in particular relates to a UWB positioning base station deployment scheme and evaluation method based on a three-dimensional model of a substation. Background technique [0002] UWB wireless positioning technology is generally used for precise positioning of people in substations. The application of this technology requires the deployment of multiple base stations in substations to ensure that the positioning accuracy reaches the centimeter level. However, when there is occlusion between the base station and the target, the signal will be reflected or refracted, resulting in a decrease in signal quality or no signal, resulting in a large positioning error. Due to the large number of devices in the substation and the heights are uneven, when deploying base stations, the deployment strategy must be planned in advance to ensure that when the target moves in the substation and c...
