| 摘 要： | 针对ISA100.11a工业无线通信网络的特点,分析了通信调度作为ISA100.11a通信协议栈核心内容的重要性,提出了一种基于时隙查询与缓冲队列的ISA100.11a DLL子网的通信调度方法.在此基础上,根据网络设备的超帧信息、链路信息以及跳信道信息等,开发了通信调度实体.该系统采用集中式管理,提供了一整套的通信资源分配机制.测试结果表明:ISA100.11a DLL子网的通信调度运行稳定,有效的避免了数据丢失、乱序等现象,改善了通信过程中的确定性、可靠性等问题.

| Abstract: | The importance of the communication schedule of the ISA100.11a industrial wireless network is discussed in the paper.In addition,one scheduling mechanism based on slot circle and buffer queue for ISA100.11a subnet is introduced.This method decentralizes the system management,provides a complete mechanisms of allocation of communications resources through employing the information of the superframe,link and channel hopping.The principle and design are employed to avoids missing or disordering packets,in orde... |
