摘要
采用MPU-9250九轴运动传感器、MSP430f5529微控制器和ZigBee技术,设计了基于惯性导航的室内消防员定位系统.根据采集到的三轴加速度和陀螺仪信息,通过步伐检测、方向判断及人员状态判定,实现了消防员的精确定位.将采集数据汇总到数据采集系统中,测试结果显示步数误差在3%以内,实现了对消防员的运动轨迹的粗略跟踪,具有一定的实际应用价值.
A firefighter indoor positioning system based on inertial navigation was put forward in this paper, in which the technologies of MPU-9250 nine axis motion sensor, MSP430f5529 microcontroller and ZigBee were used. Then, three algorithms including step detection, direction determination and firefighter＇s state determination combine with the three-axis accelerometer and gyroscope information collected by software,achieve the precise positioning of firefighters. Finally, the data will be aggrega- ted to the data acquisition system. The experiment results show that the error of step number is less than 3%, and it can recognize the current status of firemen accurately. So it has practical value to a certain extent.
