Abstract

The invention discloses an electric energy monitoring system. The electric energy monitoring system comprises an STM32F103CBT6 single-chip microcomputer; a direct-current power supply module which isa 12V / 2W direct-current power supply and can supply power to an external data collector; a communication module which uses RS485 communication and can be communicated with an external data collector;a control module which includes two paths of DO and can control ON / OFF of an external relay; and an extension module which includes two paths of CT and can be used for extending data sampling. According to the invention, two paths of electric energy can be monitored, data interaction with a data collector can be carried out through RS485 communication, 12V / 2W direct current can be provided for providing drive for the external data collector, and ON / OFF of the external relay can be controlled through a DO dry contact. High expansibility and cost control are achieved.

Description

technical field [0001] The invention relates to the field of the Internet of Things, in particular to an electric energy monitoring system. Background technique [0002] In recent years, with the popularization of the application of Internet of Things technology in all walks of life, the Internet of Things has been vigorously developed. In the new energy industry, especially new energy industries such as photovoltaic inverter systems, how to realize intelligent monitoring of electric energy has become a new research direction. Traditional electric meter measurement devices only measure electric energy, and meter reading cannot be operated remotely. Version (communication interface added), also can not carry out multi-loop monitoring and control, and needs an additional power supply to power the data collector, which cannot meet the current intelligent requirements of the power Internet of Things. The present invention researches on this, and invents an intelligent electric ...
