基于IEEE1451.2的智能变送器接口模块的设计与实现

Design and implementation of smart transducer interface module based on IEEE1451.2

IEEE1451.2标准为将不同的智能变送器连接到网络适配器(NCAP)或微处理器制定了一个统一的数字接口,真正实现了现场设备的即插即用。简述了IEEE1451.2标准,重点介绍了智能变送器接口模块(STIM)的软硬件设计思想和测试平台,通过实践验证了采用ADuC812芯片实现智能变送器接口模块的可行性。

IEEE1451.2 standard defines a digital interface for linking different smart transducers to network capable application processors （NCAPs） or microprocessors and realizes the plug-and-play function for site equipments. In this paper, IEEE1451.2 standard is resumed, the software and hardware design ideas of smart transducer interface module（STIM） and test platform are introduced. The practical tests verify the feasibility of the solution using ADuC812 to realize the STIM.
