摘要
针对智能楼宇的外墙参数高精度检测问题,提出一种新型嵌入式外墙温度和风压参数监测系统的设计方案。整体系统由多个分布式外墙节点和一个中心子系统构成。基于压力变送器PT500-503S,RFID射频识别技术、嵌入式系统及USB总线开发技术实现了系统的硬件平台,基于VC++、SQL Server 2008数据库及嵌入式C语言进行了软件系统的设计与实现。试用结果表明,该系统具有精度高、鲁棒性强、功耗低及运行稳定等特点,能够很好地满足智能楼宇高精度外墙温度和风压参数监测的需求。
To solve the problem of the exterior wall temperature and pressure monitoring system of intelligent buildings ,a novel embedded monitoring system was designed based on RFID. The system consists of multiple subsystems constituted of distributed nodes and a center subsystem. The hardware of was designed based on pressure transmiter PTSOO-503S,RFID and embedded systems and USB technology. The design of software system was based on VC＋＋, embedded C language and SQL Server 2008. Trial results show that the system has high precision,robustness,low power consumption and running stability characteristics,and the system has an expansive application prospect.
