摘要
本文对无线数据采集系统中数据链层组网机制进行了详细的分析和研究。针对竞争分配和预约分配机制存在的问题,设计和实现了一种基于动态优先级轮询机制的无线网络数据链路层协议。该系统在"公交一卡通"无线数据采集系统中得到了应用。
This paper research on the protocol mechanism of wireless data acquisition system. In allusion to the existing problems of competitive allocation and reservation distribution mechanism,it designs and realizes a wireless network data link layer protocol based on dynamic priority polling mechanism. The system is applied in the Bus Card Wireless Data Acquisition System.
