| Abstract: | For the purpose of un-contact measurement of distance,an ultrasonic device of detecting distance was designed.The construction and the application circuit of integrated DLL decoder LM567 were introduced.The demand to the input signal and its periphery components were emphasized when used as the detector of ultrasonic.The circuit and flowchart using LM567 as the detection component of the ultrasonic to detect distance were given.It was indicated by the experiment that the higher ratio of performance to price can be reached using LM567 as the IC of the ultrasonic detection. |
