常见的定位技术用于笼内小鼠跟踪准确度不高.为提高笼内小鼠定位准确性,提出了一种基于射频识别(RFID)技术的笼内小鼠定位跟踪和行为分析系统,通过放置在饲养笼下方的RFID读写器天线阵列板实现定位跟踪,上位机软件可实时显示小鼠的活动轨迹图以便科研人员对小鼠进行行为分析.通过模拟实验和生物实验,该系统可准确定位4×6阵列中小鼠位置,定位准确率可达95％以上,其中,组成阵列的单元格尺寸仅为45 mm×45 mm.
Design of tracking system for locating mice in cages based on RFID
Common positioning techniques used to track individual mouse in a population within the same cage are not very accurate.To improve the accuracy,a system based on radio frequency identification(RFID)technology is proposed for tracking and analyzing the behaviour of mice in cages,by placing an RFID reader antenna array board underneath the cage.The upper computer software can display real-time activity trajectories of mice for researchers to analyze their behavior.Simulation and experimental results show that the system can accurately locate mice in a 4 ×6 array with an accuracy of over 95％,where the cell size of the array is only 45 mm ×45 mm.
