Analysis of IEEE 1451 Intelligent Sensor Standard

智能传感器IEEE1451标准体系由7个子标准组成。IEEE1451.1模型分别为网络适配器与通信网络、NCAP与变送器模块间的通信提供软件接口,适用于单个或多个NCAP组成的系统,其传感器通过NCAP与外部网络连接。IEEE1451.1标准规定的软件接口通过对象、数据和网络通讯3种模型实现。IEEE1451.2标准则将网络化智能传感器分为智能传感器接口模块(包括电子数据表格TEDS)、网络适配器及STIM与NCAP间TII接口。

Intelligent sensor standard IEEE 1451 is composed of seven sub-standards. IEEE 1451.1 model provides software interfaces between NCAP and networks, transducers, which is fit for systems composed of one or some NCAPs and sensors are connected to networks by NCAP. Interfaces defined in IEEE 1451.1 are utilized by objects, data and communication models. IEEE 1451.2 divides network intelligent sensors into three parts： intelligent sensor interface module （including TEDS）, NCAP and TII interface between STIM and NCAP.
