超声波定位系统的研究

An Ultrasonic Positioning System

采用超声波定位系统,在较小的局域空间对移动物体进行定位。为提高该系统的性能,采用如下措施:利用成熟的无线局域网技术传输数据,使传输数据稳定、可靠;用射频技术传输超声波发送和接收端的同步信号,从而提高了定位系统中的测距精度;利用病态数学和良态数学的理论指导参考点的布置,使得由于超声波测距误差对定位系统的影响控制在允许的范围内,从而进一步提高了定位系统的精度。超声波定位系统的定位误差一般不大于6 cm。该系统具有较高的性价比,可满足在多种局域环境中对移动物体进行定位的精度需求。

The moving object in a space localized was positioned using the ahrasonic positioning system. In order to improve the performance of the system, a lot of measures were adopted, which are： making use of the mature technology of wireless local area network to transfer data stably and reliably, with radio frequency technique to deliver and receive ultrasonic synchronous signal so as to raised the ranging accuracy and by Pathological mathematis and Good state mathematics theories to direcl the layoat of reference points do limit ranging error within hounds. Generally speaking the ranging errer will not be bigger than 6 em for a ultrsonic positioing system. The result shows that the system has a higher posth moving object in differen! local area
