摘要
水下机器人的定位系统利用超声波传感器获取距离信息,同时采用三点定位法计算出位置坐标。利用单片机存储时间信息和温度信息,并将这些信息实时传送到工控机程序完成定位。最后,通过实验获取了超声波的定位数据,并采用非线性优化的方法对数据进行了分析,得到两种不同发射传感器的定位精度,对以后改进系统和提高定位精度都有参考价值。
The orientation system of underwater robot captures the distance information by the ultrasonic sensors,and uses three points location theory to compute the coordinate of the position. To save the time and temperature information by single chip computers,which transmit this information to the industrial PC to complete the orientation. Finally, we can obtain a lot of orientation data through experiment. Then we can obtain the orientation precision of two different type sensors which used for sending signals,though analyzing these data by the method of non - linear optimization. The conclusion is valuable reference for the improvement of the system and orientation precision.
