A portable ultrasonic wave concrete pouring pile detector is designed

using Android tablet as the terminal to detect parameter setting

waveform display and data analysis

it improves developing convenient and operating interactive.Using high performance chip TMS320F28335 as main control chip of lower PC.Connecting pass is set up through USB communication wire

which increases operating flexibility and convenience.The basic principle of ultrasonic wave test and main index parameters are analyzed.The system hardware circuit and software program are designed.In order to test the system performance

practical test and datas processing and analysis are carried out on test-piece in scene

the sound-time precision reaches 0.1 μs and its average standard deviation is within 2 %

consistency is good

the defects detection are accurate and reliable.The experimental results verify that the detector works stably and is easy to use with small error

and has broad application prospect in pile detecting.
