In-station positioning method for converter station

Abstract

The invention relates to positioning algorithms, in particular to an in-station positioning method for a converter station. The in-station positioning method is adaptive to complicated electromagneticenvironments and comprises a remote controller, a switch, a main AP base station, a tributary AP base station, AP hotspots, UWB (ultra-wide band) equipment and UWB chips on the basis of an in-stationpositioning device. The remote controller and the switch are both arranged in a monitoring room of the converter station, the main AP base station is mounted outside the monitoring room, the tributary AP base station is mounted outside the converter station, and the AP hotspots and the UWB equipment are mounted in the converter station. The remote controller, the switch and the main AP base station are connected for networking, the main AP base station and the tributary AP base station are connected, the tributary AP base station is connected with the AP hotspots, the UWB equipment is connected with the AP hotspots, and the UWB chips accessing to the station are connected with the UWB equipment. The UWB equipment receives pulse signals transmitted by the UWB chips, effective information signals are obtained by filtering of various noise interferences in an electromagnetic wave transmission process, and range-based positioning calculation and analysis are carried out through a centralprocessing unit to realize accurate positioning.
