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 sighificantly.Theory and computer simulation results show that this algorithm can resolve the problem of collision of many tags.
