IEEE1451标准智能传感器中网络应用处理器的实现

Design of networked capable application processor for IEEE1451 standard smart sensor

IEEE1451智能传感器接口标准为网络化传感器的互操作性与互换性提供了解决方案,在该协议的基础上,研制了系列IEEE1451标准网络化智能传感器,关键模块包括网络应用处理器(NCAP)和智能传感器模块(STIM)。详细介绍NCAP的实现方法;重点讨论关键技术的实现及其注意事项,最后,给出测试结果。通过实际测试,NCAP符合IEEE1451国际标准,传输速率达到8Mb it/s以上,能够应用于大型分布式测控领域。

The IEEE1451 smart transducer interface standard provides a method to resolve the inter-operability and inter-changeability problems of networked smart transducer; a series of standard networked smart transducer on the basis of the protocols are developed. The realization method of networked capable application processor （NCAP） is given,which is the key module of IEEE1451 standard transducer. The realization of key technology and key points are discussed. The test results＇show that NCAP adaptes to the IEEE1451 international standard,the transmission speed is more than 8 Mbit/s and it can be used in distributing measurement and control field.
