wMPS测量原理算法及优化

wMPS Measurement Algorithm and Optimization

wMPS测量基本原理算法适用于两台wMPS基站测量,存在精度低、稳定性差的问题。为了满足工业现场应用需求,提高wMPS的测量精度和wMPS系统在工业应用中的可靠性、稳定性,需要采用多发射站测量。通过数学分析,采用矢量法与最小二乘法相结合的方法,实现了多发射站同时测量某一待测点坐标的求解算法。该算法将矢量法应用在多个发射站测某一待测点算法中,从而提高测量精度及稳定性等,同时避免了原始算法中先求解水平角和垂直角,再根据两个发射站之间的距离进行待测点坐标解算,降低了运算量。

The algorithm of the wMPS measuring basic principles is used in the two wMPS transmitting sta- tions, which has some problems such as low accuracy and poor stability. In order to meet the needs of industrial field applications, improve the wMPS measurement accuracy, and the requirements of wMPS systems such as reliability and stability in industrial applications at the same time, it needs to apply multi-transmitting stations in measurement. By mathematical analysis, combination of the vector method and least squares method, the al- gorithm for a multi-transmitting station simultaneous measurement of a test point coordinates is achieved. The vector method of the algorithm in multi-transmitting stations measured in a test point algorithm is applied, thus measurement accuracy and stability are improved, the original algorithm for solving the horizontal and vertical angles are avoided. Then test point coordinates are solved stations, and the computation is reduced. based on the distance between the two transmitting
