基于HART协议的混合型环保疏浚多相流体测控系统

A Hybrid Measure and Control System for Multiphase Liquid in Environmental Dredging Based on HART Protocol

本文根据工业现场的测量与控制实际情况和技术需求 ,提出了应用HART协议的仪表混合型测控网络框架 ,说明了系统的通信方式 ,应用Delphi开发工具开发了应用于环保疏浚中多相流体测量与控制的应用程序 ,在所构造的数字仪表与模拟仪表并存的混合型测控网络基础上 ,实现了测量数据的可视化和历史数据记录 ,为更好地发挥环保疏浚系统的效能打下了基础。

According to the industrial field requirement of measure and control,a hybrid field instruments measure and control network architecture using HART protocol was presented,and communication mode of the system was explained.By using HART interface and Delphi,a series of client programs was developed to measure and control the multiphase parameters during environmental dredging course.Based on this hybrid network,the visual data and data records as a basement to promote efficiency of dredging system was obtained.
