摘　　要：智能化仪器仪表设计研究成为新一代工业制造技术突破的重要瓶颈之一;ION智能变送器是基于LonWorks总线,具有多种信息智能处理的智能变送器,能够将标准的模拟信号、传感器输出的非标准的弱模拟信号及其脉冲信号转换为数字信号,与其它控制仪表实现双向数字通讯;LON智能变送器除了具有数字调零、数字滤波等功能外,其重要特征是具有传感器故障诊断与处理功能,在传感器失效后,能够在一定时间内继续输出有效数据,保证控制系统的稳定和安全。Design and research of an intelligent instrument and meters is one of important bottlenecks by which the new generation of in- dustrial manufacturing technology makes a breakthrough. Lon intelligent transducer is based on LonWorks bus, and it can makes standard analog signal, nonstandard weak analog signal and pulse signal into digital signal and communicates with other intelligent instruments by bidi- rectional digital communication. The important feature of the transducer is the function of dealing with sensor failure, and it can continue to output valid data when the senor gets into failure at some time. So the function can keep the controlled system stable and safety.
