Embodiment 1

[0035] figure 1 The schematic flow chart that provides for the embodiment of the present invention; figure 1 As shown, the present embodiment provides a substation violation and cross-line prompt method based on ultra-wideband UWB positioning, and the method includes the following steps:

[0036] (1) According to the safety distance of the equipment in the substation, draw the safety area of ​​the equipment in the 1:1 3D model of the substation, and form a visualized 3D electronic fence;

[0037] Among them, the three-dimensional model of the substation can be realized through 3D-Max modeling, which is a common modeling method and technology for substations. Those skilled in the art can master this method through relevant books or literature.

[0038] In addition, the formation process of the visualized three-dimensional electronic fence includes the following steps:

[0039] a. Artificially set the safety distance of different voltage levels and different types of equipment...

Abstract

The invention relates to a substation illegal line-crossing prompting method based on ultra-wideband (UWB) positioning. The method comprises: a safe area of a device is drawn in a substation three-dimensional model and a visual three-dimensional electronic fence is formed; UWB positioning system deployment is carried out in the substation; according to a content of a work ticket, a corresponding working area is drawn; a staff member in the substation wears a spatial positioning device; a background carries out calculation to obtain the real-time position of the staff member; the background carries out comparison with safety fence boundary data to calculate whether someone approaches or crosses a safety distance and a corresponding working range; if any early-warning or line-crossing behavior is made, the information is sent to a smart watch worn by the staff member; the information is sent to an administrator background; and the background records data including the person doing alarming, lasting time, and a walking path of the alarm event. Therefore, the staff member and the administrator are prompted effectively; and the background records the line-crossing behavior so as to carry out follow-up work and analysis conveniently.

Description

technical field [0001] The invention belongs to the technical field of electric power maintenance, and in particular relates to a method for prompting substation violations and crossing lines based on ultra-wideband UWB positioning. Background technique [0002] In order to realize the safe production of electric power, ensure the safe and stable operation of the power grid, improve the management and maintenance level of equipment, and realize the prevention and effective control of accidents, under the guidance of the substation standardized management guidelines and standardized operation instructions, all kinds of maintenance work in substations are required Carry out standardized control of safety fences, standardize the scope of activities of maintenance personnel, make the setting of safe work scopes more clear, perfect and reasonable, and minimize the incidence of accidents. [0003] Traditional substation safety fences use physical fence entities, including left and...
