摘要：

针对坡道转弯这一特定的交通情形，设计基于无线传感器网络的坡道转弯智能交通提醒系统。采用基于粗集的约简方法对提醒点进行约简，获得最小的独立提醒点集合。利用基于有限状态机的状态图来辅助完成智能控制电路设计，进一步降低硬件造价。分析结果表明，该方法能减少提醒点和系统状态集合的数量，降低系统硬件部署的代价，提高系统的反应速度。

Abstract:

Aiming at the specific traffic difficulty at the ramp corner, this paper proposes a traffic reminder system based on Wireless Sensor Network(WSN). The knowledge reduction of rough set theory is used to get the minimum set of reminder. It simplifies the design of the control circuit. It designs the intelligent control circuit using the state diagram based on the finite state automaton, which brings down the cost of hardware further. Experiment results indicate that knowledge reduction reduces the quantity of the remainders and the system states sets, and it reduces the cost of the hardware effectively, and increases the reaction velocity of the system.

Key words: Wireless Sensor Network(WSN), automata, rough sets, reduction
