摘要
根据交通系统的具体特点,提出了一种基于ZigBee和GPRS网络相结合的方法来实现城市交通干线的覆盖思路,给出了基于ZigBee协议的链状拓扑结构无线通信网络实现方法。该方法可通过计算节点之间的RSSI值来实现智能报站和智能定位功能。
In this paper, an idea for the coverage of urban traffic trunk based on the combination of ZigBee and GPRS network is proposed. A ZigBee based chain topology for the wireless communication network was designed and realized. This method can realize bus-stop and positioning through the RSSI measurement of different nodes.
