A remote alarm device and method for electric leakage detection

Abstract

The invention discloses a leakage detection remote alarm device, which includes a power supply module, a power monitoring module, a wake-up circuit, a leakage detection module, a data analysis MCU module and an NB-IoT module, and the NB-IoT module communicates with a cloud service platform. Also discloses a leakage detection remote alarm method, including when the leakage detection probe detects the leakage voltage, the leakage detection module wakes up the data analysis MCU module through the wake-up circuit; the data analysis MCU module collects the leakage data in the leakage detection module, and if When reporting is required, the NB‑IoT module is woken up, and the NB‑IoT module transmits data to the cloud service platform; the cloud service platform determines whether to send an alarm after analysis. The invention solves the problem of fixed-point detection of the leakage position, directly detects the points where the leakage may occur, and does not focus on the leakage source, and accurately and efficiently detects the leakage of the monitored point and uploads real-time alarm data.

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
