The invention discloses a detection
system applied to shallow beach buried pipeline ultrasonic detecting and positioning. The detection
system comprises a multi-channel
signal generator module, a power amplifying module, a sound back wave receiving module and a core master control board, wherein the multi-channel
signal generator module is used for generating
sound wave emission signals with adjustable frequency, adjustable
pulse number and controllable time
delay, the power amplifying module is used for amplifying the
sound wave emission signals to high-
voltage signals and exciting an energyconverter to send
sound wave signals to a medium, the sound back wave receiving module is used for receiving the sound wave signals and comprises an isolation amplitude limiting circuit, a
voltage controlled amplifying circuit and an AD gathering circuit, the core master control board is of an eight-layer PCB structure, the sequence of stacking
layers is of a
signal layer, a
ground layer, the signal layer, the
ground layer, a power source layer, the signal layer, the
ground layer and the signal layer, bottom layer shields are added between the signal
layers, and the core master control board is used for command parameter configuration, sampling trigger, digital filtering and data communication and comprises an FPGA submodule and a
USB2.0 submodule. By means of the detection
system appliedto shallow beach buried pipeline ultrasonic detecting and positioning, the acoustic signal data can be finally obtained stably and subsequent
algorithm processing can be performed to obtain the pipeline detecting and positioning result.
