摘　　要：各种异构信息源工业设备间通信是实现智能制造关键落地技术。针对此问题,研发一种基于OPC UA的总线桥通信系统。构建嵌入式总线桥,硬件上支持与I2C接口和RJ45接口,软件上在Linux系统基础上移植UATCP协议栈,实现传感器与828D数控系统通信。实验结果表明:使用总线桥实现了底层设备与数控系统间的通信,具有跨平台性与简便性,使智能制造成为可能。The communication between various heterogeneous information sources and industrial equipment is the key technology to realize intelligent manufacturing.A bus bridge communication system based on OPC UA(OPC unified architecture)was developed for this problem.An embedded bus bridge was built,which supported the use of I2C interface and RJ45 interface in hardware,and UATCP protocol stack was transplanted on the basis of Linux system in software to realize the communication between sensor and 828D CNC system.The experimental results show that using the bus bridge to communicate the underlying equipment with the CNC system is cross-platform and simple,making intelligent manufacturing possible.
