摘要
针对超声波接收器的位置是影响超声波定位系统性能的关键因素这一问题,提出了2种超声波接收器布局方案,分别是基于正方形端点和基于正六边形端点的布局方案。根据超声波发射端与覆盖范围之间的函数关系确定所需正方形或者正六边形的数量,根据正方形或者正六边形的边长与定位空间平面的长和宽的函数关系确定所需的超声波接收节点的数量,对2种方案进行仿真实验。仿真结果表明:两定位系统的定位误差能够控制在4 cm内,基于正方形端点布局方案平均置信度为92.91%,基于正六边形端点布局方案平均置信度为95.23%;在实验中,采用固定布局方案达到了良好的定位效果,具有良好的可靠性和精确性。
Aiming at the problem that the position of ultrasonic receiver is the key factor affecting the performance of ultrasonic positioning system,two layout schemes of ultrasonic receiver are proposed,which are based on square endpoints and regular hexagonal endpoints.Firstly,the number of square or regular hexagon is determined according to the functional relationship between the ultrasonic emitter and the coverage area,and then the number of ultrasonic receiving nodes is determined according to the functional relationship between the side length of the square or hexagon and the length and width of the positioning space plane.Finally,simulation experiments are carried out on the two schemes.The simulation results show that the positioning error of the two positioning systems can be controlled within the range of 4 cm,and the average confidence of the square end layout scheme is 92.91%,and the average confidence of the hexagonal end layout scheme is 95.23%.In the actual experiment,the fixed layout scheme achieves a good positioning effect,so the layout scheme has good reliability and accuracy.
