摘　　要：针对自动测量系统中GPIB总线系统为有线连接,在应用环境上有距离、空间的限制,基于物联网思想,设计了一种基于LPC1768的Wi Fi-GPIB通信接口卡实现无线通信。硬件设计上,基于NAT9914设计GPIB接口电路。软件设计上,GPIB接口功能采用中断处理的方法设计实现;针对UDP协议可靠性的欠缺,Wi Fi通信功能利用基于Scoket编程的RUDP协议实现。实验表明,该通信卡在特殊环境下亦有良好实时性和可靠性。In view of the length space limit of GPIB Interface cable in automatic measurement , referencing the Internet of things design a WiFi-GPIB converter card based on LPC1768 to realize wireless communication. On the hardware design, the GPIB interface circuit designed based on the NAT9914. On the software design, the design of functions of GPIB interface adopt the method of interrupt. And for the lack of reliability of UI）P protocol, realize the RUDP protocol based on the Scoket programming. This card has great real-time reliability performance in special environment experiment.
