Ultrasonic Measurement System with Infrared Communication Technology

In order to achieve remote control of ultrasonic measurement system, an infrared communication-based ultrasonic measurement system is developed combining wireless communication technology with ultrasonic measurement technology. The hardware circuits of entire system and the achievement of several key technologies are discussed, including transducer structure and parameters selection, design of the corresponding circuit. The system is composed of host and slave parts. The host part is composed of host microcontroller, receiver circuit, liquid crystal display circuit and infrared communication module. The slave part is composed of ultrasonic transmitter, infrared communication modules and single-chip component. The host and slave parts transmit data through the infrared communication module. AT89S52 microcontroller is used as systems main control unit and ZHX1010 infrared communication chip for wireless data transmission. The system has low-cost, the implementation of convenient, easyto-use, convenient, flexible, reliable transmission of data, and stable performance.
