| 摘 要： | 随着社会和技术的发展，室内无线定位问题越来越受到人们的重视。GPS定位系统应用于室内定位时精度不高。本文提出采用RFID技术进行室内定位的方法。其原理是：利用RSSI（接收信号强度）来估算标签和读写器的距离，再根据读到的四个标签的坐标，采用极大似然估计方法来计算出装备有RFID读写器的机器人的坐标位置。仿真结果表明，该定位方法误差小于1m，满足室内定位的需求。

| Abstract: | With the social and technological development, wireless positioning has been paid more and more attention. The accuracy of GPS positioning system appliced indoors is not high. Radio Frequency Identi- fication （RFID）applying to indoor scale, makes good performance. This article put to use a method based on RFID to calculate indoor position. With RSSI to evaluate the distance between tags and the reader. According to the coordinates of the four tags, we can get the coordinates of the robot equipped with the RFID reader with the maximum likelihood estimation method. The simulation show that thelocalization method is. |
