资料介绍

针对传统基于时间序列的建筑能耗数据采集方法对数据量以及采样周期的要求较高,存在采集效率低以及数据丢包率高等弊端,提出基于物联网技术的大型公共建筑能耗数据采集方法。设计大型公共建筑能源系统物联网总体架构,并分析其中各层次的详细内容,设计智能数据采集器的硬件结构,以及采集器中的RS 485采集电路,通过轮询措施实现建筑能耗数据的采集流程。通过数据采集器子配置算法解决能耗数据丢失问题,采用变频采样方法对累计运算类能耗数据实施优化采样,通过勒贝格采样方法对系统实时监测类能耗数据进行改进采样。实验结果说明,利用所提方法采集的建筑能耗数据丢包率低,具有较高的采样效率和精度,可长期稳定运行。

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 Io T-based energy consumption data acquisition method for large-scale public building is put forward. The overall Io T architecture 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 circuit in the collector by means...
