煤矿井下人员安全可穿戴装置研究

Research on wearable devices for safety of underground mine personnel

  • 摘要: 针对井下人员定位系统定位精度较低、井下人员生命体征监测系统功能不全面的问题,研究了一种具有人员定位、摔倒或躺下姿态监测及心率监测功能的可穿戴装置。该装置采用RSSI测距与步距计算相结合的方法提高人员定位精度,采用三轴加速度传感器监测人员的异常动作,采用心率传感器获取心率数据。测试结果表明,该装置可以实现井下人员精确定位,能够准确判断井下人员是否摔倒、躺下,并对异常状态进行报警。

     

    Abstract: In view of problems of low positioning accuracy of underground personnel positioning system and incomplete functions of underground personnel vital signs monitoring system, a wearable device with functions of personnel positioning, falling or lying posture monitoring and heart rate monitoring was studied. The device adopts combination of RSSI ranging and step calculation to improve positioning accuracy of underground personnel. Three-axis acceleration sensor is used to detect abnormal movement of person, and heart rate sensor is used to obtain heart rate data. The test results show that the device can achieve accurate positioning of underground personnel, can accurately determine falling or lying posture of underground personnel, and alarm abnormal state.
