基于无线传感器网络的移动物体计数算法

Counting algorithm of moving object in wireless sensor networks

在低消耗环保的大背景下,基于无线传感器网络平台上移动物体计数方法存在以下不足:只能实现单通道的单向计数,或能实现双向计数但误差较大。利用类位运算思想,实现了较精确的双向计数,对解决计数中的异常出入问题———在门口徘徊,有明显效果。现场测试结果表明,该算法基本达到了最优化,并在实际应用中取得了较好的效果,计数过程不受计数对象实际大小的限制。可应用于停车场、教室、会议厅等地方的计数。

In the low consumption environmental background, the method of moving object counting in wireless sensor network platform currently remains to be perfect, which often have inadequacies such as it can realize single channel unilateral counting only, or double counting but larger error. A similar bit operation counting algorithm idea is used to realize bidirectional counting more precisely, solving the problems of abnormal passing-in and passing-out in target counting. Experimental results indicate that the algorithm reaches the better effects and the counting process is barely limited to the size of objeets, it can be used in the places such as parking lot, the classroom and conference hall.
