A ultrasonic rangefinders was made for the sake of avoiding barriers,which is going to be used for intelligent gluided vehicle.

The author introduces software and hardware composition of an ultrasonic ranging system based on single-chip control as well as its working principle and error analysis .

The ultrasonic ranging is used to design the plane location system with a high accuracy.

This paper design a new ultrasonic ranging system,which uses P89V51RB2 for the control core of the microcontroller, uses envelope detector circuit structure echo envelope,and through differential zero detection circuit set echo envelope peak time,thereby establishing the dissemination time in the ultrasonic measuring distance.

Design of new retinoscope with the ultrasonic distance measure instrument;

A liquid-level auto-control system based on ultrasonic distance measure;

This paper analyzed the disadvantage of traditional ultrasonic distance measure system,and for the actual application,designed a subaqueous ultrasonic distance measure system,which used PCI-1714 as the hardware platform,and confirmed the echo time by high speed data acquisition and correlation time-delay estimate.

Design of ultrasonic distance measurement system with high precision based on μC/OS-Ⅱ

Intelligent ultrasonic distance measurement system of CAN bus based on P87C591

An approach of hardware and software for intelligent ultrasonic distance measurement system based on CAN bus with PIC16F877A,stand-alone CAN bus controller MCP2501 and PCA82C250 was introduced.
