【摘要】：对矿井下人员定位方式和算法进行了研究,分别介绍了TOA(Time of arrival)定位视距LOS和非视距NLOS 2种场景下的定位数学模型。依据基站接收到的由井下人员携带的报警设备发出的脉冲响应电平值来判断该信号场景,在非视距场景下使用测量值减去误差值的方式,转化为视距场景下的数学模型进行计算。通过实际测试证明:定位算法具有算法简单、计算量小、精度高等优点,具有一定实用价值。
[Abstract]:The positioning mode and algorithm of personnel in mine are studied, and the mathematical models of TOA (Time of arrival) positioning line-of-sight LOS and non-line-of-sight NLOS are introduced respectively. The signal scene is judged according to the impulse response level value of the alarm equipment carried by the underground personnel received by the base station. In the non-line-of-sight scene, the measured value is subtracted by the error value, which is transformed into a mathematical model under the line-of-sight scene for calculation. The practical test shows that the positioning algorithm has the advantages of simple algorithm, small amount of calculation and high precision, and has certain practical value.
