Intelligent constant-display power monitoring device and control method thereof

Abstract

The invention discloses an intelligent constant-display power monitoring device and a control method thereof. The device comprises an electric power supply module, a system standby power supply, a power supply switching circuit, a three-phase electric quantity acquisition module, a main control MCU module, a wireless communication module, a low-power-consumption display screen module and a FLASH storage module. The master control MCU module is electrically connected with the three-phase electric quantity acquisition module, the wireless communication module, the low-power-consumption display screen module and the FLASH storage module. The electric power supply module and the system standby power supply output a power supply to an electric power monitoring device for power supply through the power supply switching circuit. When the power supply is normal, the power supply supplies power; and in a power-off state, the system standby power supply supplies power. By using the device, an online monitoring system for realizing automatic acquisition, real-time transmission, statistics and comprehensive analysis of power grid data can constantly display accumulated operation duration and accumulated power consumption under a condition of power failure, is suitable for unattended occasions, and is convenient to maintain, repair, charge and bill.

Description

technical field [0001] The invention relates to the field of power monitoring, in particular to an intelligent constant display power monitoring device and a control method thereof. Background technique [0002] With the development of the electronics industry, a large number of electronic components are widely used in the process of production practice, which makes people put forward higher and higher requirements for the power supply quality, power supply stability and reliability of the power supply system. The traditional power monitoring is The use of mechanical measuring instruments has low reliability during use, and is easily affected by the external environment and its own design defects, resulting in low measurement accuracy and accurate results, and cannot monitor the power supply system in real time. At the same time, the existing electronic power monitoring device cannot check the cumulative running time and power consumption of the equipment after power failure...
