Problems solved by technology

Low-voltage user power outages lack active sensing methods, and can only be obtained passively through user fault reports for repairs, which restricts the further improvement of customer service levels; abnormalities in low-voltage distribution network lines can only be found through manual on-site inspections, and the existing personnel are difficult to meet inspection requirements. broken problem
[0004] 2. The low-voltage user fault handling rate is low and there are many customer complaints
[0010] However, when this product is applied on a large scale, the main station system will receive a large number of household meter power outage information, which will cause information congestion in the main station system, greatly reduce the failure research and judgment ability of the main station, and even cause the main station to go down. Not suitable for large-scale application

Embodiment 1

[0039] This embodiment provides a low-voltage household meter power failure warning device based on edge computing. The warning device includes a data acquisition device and an edge computing control device.

[0040] Wherein, the data acquisition device is used to collect the power outage event data sent by the low-voltage user electric energy meter after the power outage and send it to the edge computing control device; the edge computing control device is used to perform local edge calculation on the received power outage event data , get the power failure type data and send it to the master station.

[0041] In this embodiment, the three-phase acquisition device is used to collect the outage event data sent by the electric energy meter of the low-voltage user after the power outage, and the collected data is digitized, and then transmitted to the edge computing control device for local processing. Such as figure 1 As shown, the data acquisition device includes a three-phase ...

Embodiment 2

[0045] Based on the edge computing-based low-voltage household meter power failure alarm device proposed in the above-mentioned embodiment 1, this embodiment proposes a corresponding edge computing-based low-voltage household meter power failure alarm method, such as image 3 As shown, the method includes the following steps:

[0046] In step S1, the data collection device collects the power outage event data sent by the low-voltage user electric energy meter after the power outage and sends it to the edge computing control device.

[0047] Step S21 specifically includes:

[0048] Step S11, respectively adopting the monitoring unit of the three-phase acquisition device to collect the power outage event data corresponding to the single phase after the power outage of the low-voltage user electric energy meter;

[0049] In step S12, digitize the outage event data through respective processing units, and transmit the processed data to the edge computing control device through th...

Abstract

The invention discloses a low-voltage household meter power failure alarm device and method based on edge computing. The alarm device includes a data acquisition device and an edge computing control device; wherein, the data acquisition device is used to collect the power failure issued by the low-voltage user electric energy meter after the power failure The event data is sent to the edge computing control device; the edge computing control device is used to perform local edge computing on the received power outage event data to obtain power outage fault type data and send it to the master station. The invention obtains the type of power outage and sends it to the main station by performing edge calculation of data locally, thereby reducing the concurrency pressure of the main station and avoiding downtime of the main station due to a large amount of concurrent data.

Description

technical field [0001] The invention relates to the technical field of power distribution monitoring, in particular to a low-voltage household meter power failure alarm device and method based on edge computing. Background technique [0002] The distribution network area is the carrier of urban and rural power supply. The stability and safety of the distribution network area is directly related to the power supply safety of enterprises and thousands of households, and has important economic value and social significance. In the early stage of power grid construction, more emphasis was placed on power generation and transmission, while distribution stations were often underestimated. In recent years, the country has invested a lot of money in the transformation of urban and rural power grids for the distribution network, and has transformed a large number of lines, switches and transformers, and upgraded the distribution station area in terms of hardware. However, the curren...
