摘　　要：作为一种现场总线,HART协议及相关设备被广泛地应用在工业过程控制系统中。HART协议自身也在不断发展,特别是第6版规范的提出,推动了HART的系统整合应用。针对压力类仪表,采用自主的软件状态机模型技术,设计了满足HART6规范要求的智能压力变送器,并实现对压力族命令的支持。As one type of the field buses, HART protocol and its related devices have been widely used in industrial process control systems. HART protocol is developing continuously, especially HART 6 Edition＇s releasing promotes integrated applications. Aiming at thepressure in- struments, intelligent pressure transmitter meeting HART 6 specification is designed by adopting self-developed software state machine model technology; and the pressure device family commands are supported.
