Implement of ultrasonic testing system of low-power consumption is presented in this paper.The system is based on FPGA and ARM platforms,using a modular hierarchical design.This paper focuses on the non-destructive testing methods to achieve low-power systems from both hardware and software:The isolation of transceiver circuit and amplifier by dormancy transformer coupling circuit,which reduces the voltage of the amplifier.Through the AD time-sampling technology,it reduces the working time of AD sampling and the power consumption of the system.The implement of sleep and wake-up of the device by the power management of Linux system shall reduce the time of the device.After the performance tests,it shows that the three methods proposed in this paper effectively reduce the power consumption of the system,prolong the use time of battery,improve the performance of the system and meet the requirements.
