物联网技术在大型公共建筑能耗数据采集中的应用
Application of Internet of Things technology in energy consumption data acquisition of large-scale public building
摘要
Abstract
The traditional building energy consumption data acquisition method based on time series has high requirements for data quantity and sampling period,and disadvantages of low acquisition efficiency and high data packet loss rate. Therefore, an IoT-based energy consumption data acquisition method for large-scale public building is put forward. The overall IoT architec-ture of energy system for large-scale public building is designed. The details of each level are analyzed. The hardware structure of the intelligent data collector and acquisition process of building energy consumption data realized by RS 485 acquisition cir-cuit in the collector by means of polling measures are designed. The sub allocation algorithm of data collector is used to solve the problem of energy consumption data lost. The frequency conversion sampling method is used to implement the optimal sampling for the cumulative operation energy consumption data. The Lévesque sampling method is used to improve the sampling of energy consumption data monitored by the system in real time. The experimental results show that the proposed method has low packet loss rate for the acquired building energy consumption data,high sampling efficiency and accuracy,and can operate stably for a long time.关键词
