Basic electric quantity type energy-efficiency data collecting terminal

Abstract

The invention provides a basic electric quantity type energy-efficiency data collecting terminal which comprises a micro control unit MCU, a data storage module, a power supply module and an RS485 interface, wherein the data storage module and the micro control unit MCU are in bidirectional connection; the power supply module is used for supplying power to the micro control unit MCU; the RS485 interface, a micro-power wireless module and a PLC (Programmable Logic Controller) carrier communication module are respectively in bidirectional connection with the micro control unit MCU; a metering module and the micro control unit MCU are in bidirectional connection; and a three-path voltage sampling module and a three-path current sampling module are respectively in one-way connection with the metering module. The basic electric quantity type energy-efficiency data collecting terminal is ultrahigh in anti-interference property and high in reliability. The difficulties of basic electric quantity energy-efficiency data collection and transmission are overcome, and clustering type arrangement, various data type collections, various interface transmissions and the like, which are completely suitable for industrial on-site energy-efficiency basic electric quantity collection, can be realized. Besides, the terminal meets the requirements of different working conditions, for example, a communication mode can be micro-power wireless, PLC (programmable logic control) or other signal transmission modes. An expandable interface is left for realizing future intelligent control of a master station.
