Wireless energy transmission method for power grid high potential monitoring equipment oriented sensor

Abstract

The invention discloses a wireless energy transmission method for a power grid high potential monitoring equipment oriented sensor, and belongs to the field of power grid high potential monitoring. The method comprises the following steps: (1) before energy is supplied for the sensor, starting a tracking aiming unit of the system, and beginning to automatically search a wireless energy receiver ata receiving end; (2) after the wireless energy receiver is aimed by a wireless transmitter, increasing power to start energy transmission, collecting fed-back positional information parameters of thewireless energy receiver in real time according to an upper computer by the tracking aiming unit in the period to constantly adjust the posture, and thus completing real-time tracking energy transmission at the receiving end; and (3) in the energy transmission period, carrying out real-time monitoring on the electric quantity of a storage battery at the receiving end by the energy monitoring unit, and controlling the turning-on and turning-off of a driving source according to the electric quantity. Efficient and continuous energy supply for the monitoring equipment oriented sensor is realized, and the energy supply operation of workers for the monitoring equipment sensor is completed in a safe region in a remote non-contact mode.

Description

technical field [0001] The invention relates to a wireless energy transmission method for a sensor of a high potential monitoring equipment of a power grid, and belongs to the field of high potential monitoring of a power grid. Background technique [0002] With the development of power system automation and smart grid, real-time monitoring of high-voltage power equipment is becoming increasingly important, and the application of smart electronic devices and monitoring sensors in power transmission and transformation equipment is becoming more and more extensive. In order to accurately monitor various physical quantities of electrical equipment, a large number of sensor nodes of various types will be densely distributed in the area to be measured. Usually, sensors and electronic equipment are powered by low-voltage DC, but in the complex working environment of medium and high-voltage electrical equipment, the conventional method of artificially replenishing sensor node energ...
