Internet-of-Things modular electric energy meter capable of meeting temperature monitoring of terminal block

Abstract

The invention provides an internet-of-things modular electric energy meter capable of meeting temperature monitoring of a terminal block, which comprises a metering core mainboard, a management core mainboard, an expansion module and a communication module, wherein the metering core mainboard is provided with a metering module, the metering module comprises an MCU module, a voltage and current sampling module, a battery, a super capacitor, an RTC clock module, an ESAM module, a storage module, a pulse signal module and a power supply module, the management core mainboard is provided with a management module, and the management module comprises an MCU module, a terminal temperature measurement module, a key, an ESAM module, a liquid crystal display screen, a backlight module, a Bluetooth module and a storage module. The metering function can be independent, the metering core and the management core are in a separated state, once software or hardware faults occur, the troubleshooting time can be greatly shortened, the faults can be positioned more accurately, the faulted core can be directly replaced with the core with the normal function, and the plug-and-play effect is achieved.

Description

technical field [0001] The invention relates to the technical field of electric energy meter communication, in particular to an Internet of Things modular electric energy meter that meets the temperature monitoring requirements of terminal blocks. Background technique [0002] The Internet of Things energy meter is the product of the integration and development of smart grid construction and smart Internet of Things. The Internet of Things (abbreviation: IoT) is a network based on information carriers such as the Internet and traditional telecommunication networks, enabling all ordinary objects that can perform independent functions to realize interconnection. [0003] At present, between 2013 and 2017, a total of 457 million smart meters have been invested and installed, and the design method is integrated. If the phase wire and neutral wire terminals of the electric energy meter are abnormally overheated, electrical failure may occur. The temperature rise of the equipment...

AI Technical Summary

Problems solved by technology

If the phase wire and neutral wire terminals of the electric energy meter are abnormally overheated, electrical failure may occur. The temperature rise of the equipment will cause the equipment to burn out, and seriously affect the safety of the user's electricity use. Considering the safety factor, a A device capable of real-time monitoring of the terminal temperature of the incoming and outgoing lines of the electric energy meter

In the existing electric energy meter, when the inspection personnel need to measure the temperature of the equipment terminal, they must use an infrared temperature measuring gun to measure the temperature of the terminal copper bar. The work efficiency is low, and safety accidents are generally not easy to prevent in advance.

It is impossible to monitor the running status of the electric energy meter in real time

And with the long-term investment of the product and the poor storage environment, etc.
