摘要
IEEE1451.2标准定义的TEDS技术使智能变送器具有自我描述和自识别能力,是智能变送器实现即插即用的关键;对IEEE1451.2标准下的智能变送器模型进行了研究,以XC2S50为主控单元设计了智能执行器接口模块,并从硬件和软件两个方面阐述了具体的实现方法;该模块采用TEDS技术,具备TⅡ接口通信能力;用测试系统对智能执行器接口模块进行测试,测试结果表明:该模块能与测试系统实现无缝连接,能被系统智能识别和控制。
The TEDS technology which IEEE 1451.2 standard defined makes smart transmitters have the capacity of self--description and self--recognition, it is also the key for smart transmitters to realize plug and play. The paper introduces the transmitter model of IEEE 1451.2 standard, designs a smart actuator interface module by using XC2S50 as the control unit and describes the specific implementation methods from both hardware and software. The module uses TEDS technology and has TII interface communication capabilities. System test shows that： The module can be seamlessly connected with the system and it can be intelligent identification and controlled by the system.
