【摘要】：對礦井下人員定位方式和算法進(jìn)行了研究,分別介紹了TOA(Time of arrival)定位視距LOS和非視距NLOS 2種場景下的定位數(shù)學(xué)模型。依據(jù)基站接收到的由井下人員攜帶的報警設(shè)備發(fā)出的脈沖響應(yīng)電平值來判斷該信號場景,在非視距場景下使用測量值減去誤差值的方式,轉(zhuǎn)化為視距場景下的數(shù)學(xué)模型進(jìn)行計算。通過實(shí)際測試證明:定位算法具有算法簡單、計算量小、精度高等優(yōu)點(diǎn),具有一定實(shí)用價值。
[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.
