基于嵌入式的建筑能耗数据采集器的设计

Design of Building-energy Consumption Acquisition Unit Based on Embedded System

在建筑能耗监测系统中,建筑能耗数据采集器是实现建筑能耗数据分类、分项采集的关键设备。建筑能耗数据采集器负责采集监测区域内的电、水、燃气等计量装置的计量数据,同时也需要具备能耗数据本地分析、存储和网络转发的功能。介绍一种基于S3C6410 ARM11平台的建筑能耗数据采集器设计方案。该方案通过Internet方式实现与上级数据中心的数据通讯功能,使用RS-485总线完成各种能耗计量数据的采集。该设备配备了SD卡存储器和USB扩展接口模块。描述了建筑能耗数据采集器的硬件组成和软件设计,并给出详细的硬件结构设计方案。

This paper introduces the design of building-energy consumption acquisition unit based on S3 C6410 ARM11 platform.Though Internet and RS-485 bus,the scheme complete data communication with the data center and meter.This equipment also includes secure digital memory card and USB 2.0 interface.This paper describes hardware structure and software module of the design.
