文档介绍：基于LABVIEW的智能热量表
摘要
本文设计了一种新型的暖气表以及与之配套的远程抄表系统。整个系统由户机、采集器、PC机三部分组成:户机通过实时测量热水的瞬时流量及温度,得到用户在一段时间内的用热量;测量数据通过采集器可以远传至物业管理中心的PC机,由管理中心统一完成数据存储,数据查询,数据打印等多项任务。
本文包括整个系统的硬件和软件设计,重点介绍了物业管理中心的PC机管理软件部分。软件部分用LabVIEW,LabVIEW 是美国 NI 公司实现虚拟器(Virtual Instrument-VI)技术的G语言。图形化编程开发平台的特点是基于通用计算机等准软硬件资源平台,实现构建灵活、层次体系明晰、功能强大且人机界面友好的测控系统,此在国内外许多测控应用中被广泛采用,并具有丰富的统计、计算,数据储存等功能;具有广泛的扩展升级空间。

Abstract
This paper developed a new kind of heating table with the necessary long-distance meter reading system. The whole system consists of heat table, collector, PC three parts: heat table receive the heat of users in a period of time through real-time measuring hot water temperature and the instantaneous flow; the measurement data can be transmitted to property management center of PC through the terminal, finally the management plete data storage, unified data query, data printing missions.
This paper expounds the system hardware and software design, and emphatically introduces the property management center of PC management software. Software adopts LabVIEW, which is the United States LabVIEW Virtual device (Virtual Instrument - VI) technology G language. The characteristic of graphical programming developed platform is based on puter software and hardware resource platform and realizes the construction of accurate, well arranged, powerful and friendly man-machine interface system, the application is widely used in Measurement and Control field at home and abroad. And It has rich statistics, calculation, data storage function and widely extended upgrade space.
