摘要
详细介绍了一种机器人超声测距系统,测距范围0.2~5m,具体设计了基于单片机控制的3路超声测距系统的软、硬件,并介绍了该系统的构成、工作原理最后,通过实验获得3路测距数据,同时利用误差补偿的方法得到测距系统所要求的精度±4cm还给出了该单片机应用系统与上位机之间的通讯等利用本系统及其设计方法作为农业机器人辅助视觉系统。
The article particularly introduces a robotic ultrasonic ranging system.It is able to measure the distance from 0.2 to 5 meters.The hardware and the software of three points ultrasonic ranging system is practically designed by means of control technology of single chip computer,and the structure and principle of the system are introduced.The ultrasonic ranging data is obtained through experiment and the requested accuracy(±4cm) is gained utilizing the method of error compensation.The article also gives the communication method between the single chip computer applied system and the upper computer. The authors believe that the scheme of the system and its designing method can be used as the aided visual system of agricultural robot.By means of it,the robot can obtain the messages of the distance and the roughly shape about the crops.
