Abstract

The invention discloses a low-power-consumption partial discharge signal monitoring method and device based on a LoRa technology. The method is applied to a partial discharge signal monitoring device, and the method comprises the following steps: S110: obtaining first power-on information of a first monitoring node; S120, according to the first power-on information, the first monitoring node carrying out first registration on the sink node according to a preset communication mode; S130, judging whether the first registration is the first registration or not; S140, when the first registration is not the first registration, judging whether the first power-on information is triggered by the first sensor; S150, when the first power-on information is triggered by the first sensor, obtaining partial discharge data according to the first sensor; S160, the first wireless communication module transmitting the partial discharge data to a sink node through a preset communication mode; wherein M is greater than or equal to 1 and is a positive integer. The technical effect of reducing the power consumption of the partial discharge signal monitoring equipment while finding the partial discharge signal of the power equipment in time is achieved.

Description

technical field [0001] The invention relates to the technical field of discharge monitoring, in particular to a method and device for monitoring partial discharge signals with low power consumption based on LoRa technology. Background technique [0002] In the field of partial discharge detection, multiple wireless sensor nodes are generally installed for electrical equipment to detect the health of electrical equipment. [0003] In the prior art, sensors are often used to monitor the partial discharge of the power equipment in real time, so as to detect the partial discharge of the power equipment in time. However, there are uncertainties in the phenomenon of partial discharge. Although this method can detect the partial leakage of electric equipment in time, the power consumption of the monitoring equipment is large and the service life of the battery is short. Contents of the invention [0004] The present invention provides a low power consumption partial discharge si...
