摘　　要：满足移动医疗设备的区域性定位、运行轨迹跟踪及现场可视化管理需求,实现重点区域的越界和入侵告警管理。基于CSS技术和边缘计算技术,设计医疗设备定位管理系统,定义系统层次功能,优化定位滤波算法,构建实验测试系统并完成系统性能测试。经过Kalman滤波后,系统定位精度可提高到1 m左右,传输速率为1 Mbit/s信号。在1μW功率下,传输距离可达5 m,在6.3 mW功率下,传输距离可达26 m。所设计方案可实现覆盖大范围区域的移动医疗设备的智能追踪,及时、准确地将各个区域设备的动态情况反映到中心监控平台,使管理人员能够随时掌握布控区域设备的分布状况和每个受控对象的运动轨迹,进而实现更加合理的管理。To meet the needs of regional positioning,operation track tracking and on-site visual management of mobile medical equipment,it is wished to realize the management of cross-border and intrusion alarm in key areas. Based on CSS technology and edge computing technology,the medical equipment location management system is designed,the system level functions are defined,the location filtering algorithm is optimized,the experimental test system is constructed and the system performance test is completed. After Kalman filtering,the positioning accuracy of the system can be improved to about 1 m,the transmission speed is 1 Mbit/s,the transmission distance can reach 5 m under 1 μW power,and 26 m under 6.3 mW power. The designed scheme can realize the intelligent tracking of mobile medical devices covering a large area,timely and accurately reflect the dynamic situation of devices in each area to the central monitoring platform,so that managers can master the distribution of devices in the control area and the movement track of each controlled object at any time,and then realize more reasonable management.
