Addressing Receiving Strategy and Circuit System Design of 8+8 Ultrasonic Sensor Array Based on PZT
The signal-receiving method of the addressing ultrasonic transducer array differs from that of the traditional ultrasonic transducer array. The number and distribution range of receiving array elements can be flexibly selected to achieve variable receiving aperture with a simplified circuit scale. In this study, an 8+8 (64 element) scale addressing excitation ultrasonic array receiving strategy based on lead zirconate titanate (PZT) is proposed, and an addressing receiving circuit based on a microprocessor and PMOS electronic switch is designed. The electrical characteristics of the ultrasonic array are tested and analyzed. The echo signals of the bottom surface of aluminum and steel blocks are tested in four addressing receiving modes: single-array element, whole-row array elements, whole-column array elements, and all array elements.
