| Abstract: | The principle of the ultrasonic position-meter was introduced, the position measuring system was given with the single chip microcomputer, and the ultrasonic generating and receiving circuit were designed. To realize the multi-position management, the serial communication circuit was designed. The problem of temperature influencing the position measurement was discussed and the solution was put forward. The detecting error was analyzed on the basis of test as well. |
