Abstract

Building energy consumption monitoring and management system have been developed widely in China in order to gain the real-time data of energy consumption in buildings for analyzing it in the next state work. This paper describes a low-cost and small-sized collector based on the STM32 microcontroller, which can be placed in a building easily to implement the work of data acquisition, storage, and transmission. The collector gathers the electricity, water, heat, and energy consumption data through the RS485 field bus and stores the data into an SD card with mass storage, finally, using Internet to finish the communication and transmission to data server through TCP protocol. The collector has been used in application for two years, and the results show that the system is reliable and stable.

Highlights

With the rapid growth of world energy uses, increases a series of serious problems, such as supply difficulties, exhaustion of energy resources, and negative impact on the environment
The main work for the system of data acquisition and transmission is to collect energy consumption data from terminal meters which are installed in buildings periodically, store the data after analyzing and processing, and transmit the data to data server through Ethernet
The collector has been used in building energy consumption monitoring platform in Liaoning province and in the superintend platform of economical campus for Taiyuan University of Technology

Summary

Introduction

With the rapid growth of world energy uses, increases a series of serious problems, such as supply difficulties, exhaustion of energy resources, and negative impact on the environment (atmospheric pollution, greenhouse effect, climate change, destroy of ozonosphere, etc.). In China, the energy consumption has become 2 times at an average growing rate of 3.7% [1], and China has passed the US to become the world’s biggest energy consumer, based on the new data from the IEA. In the future, this growing trend will continue, and the demand is still growing in absolute terms. Energy saving of buildings becomes one of the major tasks of promoting energy conservation and raising the efficiency of energy consumption. Transformation of the old buildings is currently facing a major problem that experts and scholars have repeatedly stressed on when talking about the promotion of energy-saving construction. Almost nobody knows when energy consumption occurs and where it takes place; the users can make more sensible decisions to lower the energy consumption if they find out where and when the energy consumption happens in a well and true way [2]
