Comprehensive electricity consumption measurement and control management terminal

Abstract

The invention discloses a comprehensive electricity consumption measurement and control management terminal and belongs to the technical field of electric use safety and energy conservation. The terminal comprises a microcontrol unit and an illumination intensity acquisition module, a human body induction module, an electric quantity acquisition module, a data storage module, a real-time clock module, a Lonworks intelligent receiving and transmitting device, an RS485 communication interface and a man-machine interaction interface platform which are all connected with the microcontrol unit. By means of the terminal, energy consumption conditions of electric appliances in a building can be accurately monitored, statistical analysis of the energy consumption conditions and energy consumption charging are facilitated, the terminal has various energy-saving control modes and can be conveniently set, bases are provided for flexible control strategy implementation of a comprehensive energy management system, and the effects of reasonably using energy and reducing energy consumption are achieved. Consumption reduction indexes can be sent through the system in the electricity use peak hours, the set temperature is automatically adjusted through a temperature controller, and the aim of reducing consumption is achieved. The terminal can be widely applied to energy-saving systems of an air conditioner, an illumination device and other electric appliances of the building.

Description

technical field [0001] The invention belongs to the technical field of electricity safety and energy saving, in particular to a comprehensive electricity measurement and control management terminal. Background technique [0002] In order to meet the needs of future economic and social development, comprehensively support the development of clean energy and low-carbon economy, meet the requirements of advanced technology, cost-effective, diverse services, flexible interaction, and friendly and open smart electricity consumption under the smart grid, and build power grids and user energy flow A new type of power supply and consumption relationship that interacts in real time, information flow, and business flow has become a mainstream in today's era. The total annual power consumption of large-scale buildings in my country accounts for 10% of the total national consumption, and the energy cost exceeds 80 billion yuan, mainly including large-scale buildings such as government a...

Problems solved by technology

At present, most of the energy management equipment on the market is aimed at the control and measurement of a certain electrical equipment, and can deal with a wide variety of electrical equipment. If you want to centrally manage the electricity consumption of the entire building, you need multiple hardware products to control and measure separately. , and the interface protocol of each hardware product is not completely unified, which not only wastes cost, but also is not easy to manage

Most of the integrated energy management systems use energy consumption classification and sub-item, and each subordinate branch has multiple branch metering, and there is no centralized and friendly user interface, which is convenient for users to query
