摘　　要：电阻焊控制器与上位机PC之间,需要高速可靠地传输大量数据。通用串行总线USB具有使用简便、支持热插拔以及传输速度快等优点,文中研究设计了以PDIUSBD12为USB桥接芯片,STC89C52RC为控制器的USB接口设计方案。用C51语言设计了相应的USB固件程序,在VC++6.0环境下编写客户端的驱动程序以及上位机人机界面,实现了PC机与电阻焊控制器之间的双向数据传输。试验表明:该接口系统硬件简单、软件移植性好,可以加以推广运用于其他各类焊机的通信系统中。Communication between resistance welding controller and PC requires high speed and reliable transmission of large amount of data. Universal serial bus USB has the following advantages： convenient to use,support hot-swappable,and high speed.This research discussed a USB interface with PDIUSBD12 as USB bridge chip and STC89C52 RC as the controller. The USB firmware was designed with C51. The client driver and PC interface were compiled under VC ＋ ＋ 6. 0 environment. Test results show that the interface is simple,feasible and has a fine portability,it can be used in communication systems for various kinds of electric welding.
