| 摘 要： | 为了防止井下人员跟踪定位系统中多个射频标签同时向基站发送识别信息时产生的碰撞问题,提出了一种基于搜索矩阵的自适应防碰撞算法.该算法有效利用碰撞信息,通过构造搜索矩阵进行读取,通过引入碰撞栈,并根据时隙状态自适应调整搜索路径的方法,使碰撞概率大大降低.理论和仿真实验证明,该算法能够有效解决多目标识别的防碰撞问题.

| Abstract: | In order to avoid signal collision occurs when more than one mobile tag send the recognition information to the base station with function of personnel tracking system in mine,an adaptive algorithm based on search matrix is proposed.In this algorithm,the information of collision bits is used effectively,by constructing a search matrix for reading,the stack through the introduction of the collision,and adaptive adjustment of status based on the search path slot ways,the probability of collision is reduced si... |
