Transformer substation multi-target accurate sound positioning system

摘要

The invention relates to a transformer substation multi-target accurate positioning system, which comprises an intelligent positioning terminal, a sound positioning beacon node and a wireless data transmission base station. The intelligent positioning terminal can match with the sound positioning beacon node so as to perform a time synchronization on the sound positioning beacon node, and then send an ultrasonic positioning signal; the sound positioning beacon node can decode the ultrasonic signal sent by the intelligent positioning terminal to obtain positioning information by matching with the intelligent positioning terminal so as to perform the time synchronization, and transmit the positioning information to the wireless data transmission base station; and the wireless data transmission base station processes the positioning information transmitted by the sound positioning beacon node so as to obtain a position coordinate of an operator wearing the intelligent positioning terminal. The invention can position site plants in the transformer substation, identify and dynamically position the operator, ensure that the operator operates according to rules, and provide alarm bases for a violation operation which is out of scope or time, which is performed on wrong operation objects, or which destructs safety precautions.
