摘　　要：网络化智能传感器接口标准IEEE1451.2通过定义软件上TEDS(transducer electronic data sheet:传感器电子数据表格)和硬件上的TII(transducer independent interface:传感器独立接口)使传感器的即插即用成为可能。TII接口的NACK响应协议是接口控制和数据传输功能实现的基础,是实现基于IEEE1451.2的传感器智能接入模块(STIM,smart transducer interface module)的关键部分。设计分析了NACK响应的各种情况,并加以实现,经仿真验证,达到标准要求。Networked smart transducer interface standard--IEEE1451.2 makes transducer＇s Plug and Play possible through TEDS （transducer electronic data sheet） and TII（transducer independent interface）.The NACK response protocol of TII is the base of the implementation of control and communication of TII, and is critical to implement smart transducer interface module based on IEEE1451.2.The design analyses all occasions when NACK happens, and implements them. The NACK response can meet the requirement of standard after simulation.
