Electric leakage detection remote alarm device and method

Abstract

The invention discloses an electric leakage detection remote alarm device which comprises a power supply module, a power supply monitoring module, a wake-up circuit, an electric leakage detection module, a data analysis MCU module and an NB-IoT module, and the NB-IoT module communicates with the cloud service platform. The invention also discloses an electric leakage detection remote alarm methodwhich comprises the following steps: when the electric leakage detection probe detects an electric leakage voltage, the electric leakage detection module awakens the data analysis MCU module through the awakening circuit; the data analysis MCU module collects electric leakage data in the electric leakage detection module, and awakens the NB-IoT module if reporting is needed after sampling analysis. The NB-IoT module transmits data to the cloud service platform; and the cloud service platform determines whether to give an alarm after analysis. According to the method, the problem of fixed-pointdetection of the electric leakage position is solved, the point position where electric leakage possibly occurs is directly detected, the electric leakage source is not focused on, and electric leakage detection and real-time alarm data uploading of the monitored point position are accurately and efficiently carried out.

Description

technical field [0001] The invention relates to the technical field of the Internet of Things, in particular to a low-power consumption wide area network leakage alarm device for detecting whether there is leakage on an object based on a three-electrode method. Background technique [0002] With the development of economy and society, various types of electrical equipment in public places are increasing, and the risk of leakage is also increasing. In recent years, there have been frequent incidents of casualties caused by electric leakage of street lamps, billboards and other electrical facilities, causing huge property losses and endangering personal safety. The hidden dangers and risks of electric leakage of such power facilities have attracted great attention from management departments at all levels, and there is an urgent need for practical and effective monitoring methods to prevent problems before they happen. [0003] At present, the detection of leakage focuses mor...

AI Technical Summary

Problems solved by technology

[0003] At present, the detection of leakage mainly focuses on the leakage of the line, and judges whether there is a risk of leakage by detecting the abnormal current on the line, but it is impossible to judge whether there is a leakage at a certain point

In fact, the leakage power source at a certain point may be diverse and complicated, no matter which leakage power source causes the leakage, it may cause irreparable losses, and the abnormal current detection based on the line has a high rate of false alarms and The fatal flaw that cannot accurately judge the leakage point
