Description
Technical Field
The utility model belongs to the technical field of the power feed detects, especially, relate to an earth connection monitoring system based on UWB ultra wide band location.
Background
The auxiliary power of hydropower stations, thermal power stations or wind power plants in the power industry often needs to use a grounding wire in the switching operation process, and the grounding wire is mainly used for grounding the maintenance equipment (a bus, a switch, a knife or a transformer) before maintenance operation after power failure so as to prevent voltage from accidentally injuring workers. After the maintenance operation is finished, the grounding wire must be removed before power transmission is prepared, otherwise, accidents such as grounding trip, equipment damage, casualties and the like are easily caused. Therefore, after the maintenance work is completed, it is necessary to check and confirm whether or not the ground wire is removed before the power transmission is resumed.
The traditional ground wire dismantling, checking and confirming mode adopts a positioning mode with low precision and an inaccurate detection result, and the traditional mode adopting a mobile network is poor in data transmission and detection stability and easy to interfere with signals.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide an earth connection monitoring system based on UWB ultra wide band location just in order to solve above-mentioned problem, include:
the UWB positioning tag is arranged at the end of the grounding wire and used for monitoring the position state of the grounding wire, sending an UWB pulse signal and transmitting positioning data back to the UWB positioning base station;
the ultra-wideband positioning base station is used for receiving ultra-wideband pulse signals sent by the ultra-wideband positioning labels and transmitting the ultra-wideband pulse signals back to the monitoring server;
and the monitoring server is used for receiving the positioning data and monitoring the position state of the grounding wire.
The beneficial effects of the utility model reside in that: the utility model discloses an installation ultra wide band location basic station installs UWB ultra wide band positioning signal terminal again and can realize the real-time location to the earth connection, has improved positioning accuracy and data transmission speed, avoids appearing data transmission and disturbs, guarantees the accuracy of earth connection monitoring.
