Precise positioning device and method for power transmission line maintenance workers

Abstract

A precise positioning device and method for power transmission line maintenance workers belongs to the technical field of power system safety production management and control, and comprises a data server, a geographic information system (GIS), an electronic fence setting, an on-site video acquisition module, a Beidou positioning system (BDS) module, a positioning anchor point label, a worker wireless positioning base station and a worker wireless positioning portable terminal. The positioning algorithm is characterized in that the personnel positioning terminal realizes sensor network initialization, anchor point information broadcasting, information exchange, anchor point PTI test, overlap area scanning and weighted centroid algorithm, the coordinates of the portable positioning terminal are calculated, and then the portable terminal is accurately positioned. According to the invention, the positioning precision of the power transmission line maintenance workers can be improved, the system composition is simple, the field installation is convenient, the equipment types are few, real-time data uploading can be realized, the field operation requirements are met, and the safety and effectiveness of high power transmission line maintenance are further improved.

Description

technical field [0001] The invention belongs to the technical field of power system safety production management and control, and in particular relates to a precise positioning device and method for transmission line maintenance operators. Background technique [0002] Transmission lines undertake the important task of electric energy transmission, so the safety and reliability of transmission lines are related to the stable supply of electric energy, industrial production and residents' lives. However, the transmission line covers a wide area, the area span is large, the on-site maintenance operation environment is complex, the conditions are harsh, and the positioning deviation of traditional personnel is large, which cannot meet the accuracy requirements of on-site operations. [0003] The improvement of positioning accuracy of traditional on-site positioning equipment depends on increasing the deployment density of positioning base stations. Since the networking between ...

However, the transmission line covers a wide range, the area span is large, the on-site maintenance operation environment is complex, the conditions are harsh, and the positioning deviation of traditional personnel is large, which cannot meet the accuracy requirements of on-site operation

[0003] The improvement of positioning accuracy of traditional on-site positioning equipment depends on increasing the deployment density of positioning base stations. Since the networking between base stations is mostly through wired transmission methods such as optical cables and buses, which require external power supply, the investment required to improve positioning accuracy, The amount of work such as cable erection and the construction period of the project are rapidly increasing
