Ultrasonic Phased Array Transceiver with Low Power Consumption

Abstract

The invention discloses a low-power-consumption ultrasonic phased-array transmitting and receiving device. The low-power-consumption ultrasonic phased-array transmitting and receiving device comprises a wave beam receiving module, a wave beam transmitting module and a field programmable gate array (FPGA) module, wherein a wave beam control unit and a time sequence control unit are arranged in the FPGA module; the time sequence control unit is energized to control the wave beam transmitting module and the wave beam receiving module to work alternately in sequence. Two different state signals are respectively output to the wave beam transmitting module and the wave beam receiving module in a mode of using the FPGA module as a state machine; after the condition of finishing energizing is realized, the wave beam transmitting module is controlled to work, and the wave beam receiving module is controlled to stop working; after transmission is finished, the wave beam receiving module is controlled to work, and the wave beam transmitting module is controlled to stop working; therefore, the wave beam transmitting module and the wave beam receiving module can work alternately, an idling time period of the wave beam transmitting module and the wave beam receiving module is avoided, the energy consumption of elements can be maximally reduced, and the low-power-consumption ultrasonic phased-array transmitting and receiving device is extremely applicable to a portable ultrasonic nondestructive flaw detector.

Problems solved by technology

[0003] The existing ultrasonic testing technology has been widely used in the industrial field as a mature non-destructive testing technology, especially in the fields of aerospace and pipeline transportation. Some industrial flaw detectors are no longer applicable due to reasons such as large size, complex structure, and unsuitability to carry. Therefore, portable ultrasonic nondestructive flaw detectors gradually appear in this field. Because portable ultrasonic nondestructive flaw detectors need to be portable and easy to operate, Therefore, its power supply is powered by an independent power supply, and the high power consumption has become a problem faced by existing portable nondestructive flaw detectors.
