Study on software part of ultrasonic ranging system based on variable emission wavelength

摘要

At present, ultrasonic technology is widely used in measurement, automobile, medical, chemical industry, aerospace, machinery, exploration, biology, food and other fields, especially in the detection distance. The reason why autonomous mobile robots can move autonomously is that there is obstacle avoidance or positioning system in the robot system. The robot uses ultrasonic technology in detecting the distance of obstacles. In view of this, this paper introduces a fully integrated high-speed, high-performance hybrid signal processing system MCU, which controls receiver and transceiver ultrasonic range finder. In this paper, the design scheme of software system for ultrasonic range finder is expounded in detail, and the solution for the blind area of ultrasonic is given. Finally, the rangefinder is mounted on the robot for practical testing. The test data show that the Ultrasonic distance measurement finder described in this paper has good ranging performance, and it can meet the requirements of robot rangefinder.
