改进LANDMARC算法在舱室作业人员轨迹定位中的应用

摘要

针对船舶修造企业舱室的特殊工作环境的安全要求，提出一种以RFID射频技术为基础的人员定位系统，以实现船上人员的轨迹分布与精准定位。采用改进的LANDMARC算法，通过用距离替换RSSI值对传统的LANDMARC算法进行改进，解决在空间定位中的偏差问题。在实验环境下对系统的设计思路进行了验证，结果表明改进的 LAN-DMARC算法具有更高的定位精度，可用于船舶修造密闭舱室作业人员的跟踪定位。%Aiming at the safety requirements of the special working environment of ship building enterprise cabins, a personnel positioning system based on RFID radio technology is proposed to realize the trajectory distribution and pre-cise positioning of ship personnel. By using the improved LANDMARC algorithm, the traditional LANDMARC algo-rithm is improved by replacing the RSSI value with distance to solve the problem of spatial localization. The results show that the improved LANDMARC algorithm has higher positioning accuracy and can be used in the tracking and positioning of ship building and confined cabin crews in the experimental environment.
