摘　　要：对目前常用的几种工业无线标准进行了简单比较,并着重介绍了低速无线个人区域网络的新标准IEEE 802.15.4a及其关键技术MDMA和CCS。新标准采用Chirp扩频物理层技术作为物理层标准,对工业环境中的干扰等具有很强的鲁棒性。以IEEE 802.15.4a为基础,在现场总线测控系统中构建了无线子网段,实验表明系统处于稳定运行状态,且满足一般流程工业要求。该实例为工业无线网络接入到有线网络提供了一种解决方案,新标准在工业现场的短距离传输方面将会有广阔的应用前景。Several commonly used industrial wireless standards have been compared in brief, and the new standard IEEE 802.15.4a for low data rate wireless personal area network （ WPAN ） , and its critical technologies MDMA and CSS are introduced emphatically. In the new stand- ard, the Chirp spread spectrum physical layer technology is used as physical layer standard, it features strong robustness to interference in industrial environment. With IEEE 802.15.4a as the basis, the wireless subnet is built in fieldbus measuring and control system. The experiment indicates that the system operates stably and meets requirements of normal process industries. The practical example provides a solution for merging industrial wireless into cable network. The standard will be widely used in short distance transmission for industrial fields.
