摘　　要：针对二线制智能阀门定位器的低功耗特性,基于自适应控制理论,设计了一种基于HART协议的智能阀门定位器。分别对HART通信协议、协议接口等技术进行了研究,并具体给出了HART通信的阀门定位器原理和智能阀门定位器的软硬件设计方案。现场运行表明,系统的稳态精度、动态响应特性等技术指标均较好地达到了预定要求。系统具有广泛的市场需求,并将在相当长的时间内发挥主导作用。Aiming at the feature of low power consumption of two wired intelligent valve positioner, an intelligent positioner for electric valve has been designed based on HART protocol and self-adaptive control theory. The technologies of HART communication protocol and protocol interface are researched, and the principle, design strategies of software and hardware of this positioner are given concretely. The field operation shows that the technical indexes in stability and dynamic respondent characteristic of the system well reaches the predicted demands. The system meets wide applicable market requirement, and will play a leading role in certain period ahead.
