Title:
SMART ELECTRICITY METER TERMINAL
Document Type and Number:
WIPO Patent Application WO/2022/247089
Kind Code:
A1
Abstract:
A smart electricity meter terminal, comprising: a core board, an expansion board and an external sensor, wherein the expansion board is connected to the core board by means of a GEC interface, and the expansion board is connected to the external sensor by means of a universal interface; the core board comprises an MCU and a communication module, which is connected to the MCU by means of a fixed interface; the expansion board comprises photosensitive and thermosensitive sensors, a program download interface, a power source interface and a work indicator lamp; and the external sensor comprises an LCD and a power grid data sampling sensor. A hardware circuit modularization design idea is used for the AHL NB-IoT-based electricity meter terminal, such that a hardware circuit can be rapidly reused; and a component-based design idea is used for a hardware entity, such that a hardware terminal can be quickly upgraded.
