Ultrasonic testing system based on Bluetooth technology
Xiao Chen, Shandong Xiao · 2009
To achieve the remote control and automation of ultrasonic testing equipment, a Bluetooth-based ultrasonic testing system was developed with single-chip microcomputer as the core and wireless communication technology for data transmission. The system is composed of master and slave units. The slave unit includes the ultrasonic transmitter and receiver circuits, Bluetooth communication module and the microcontroller. It is responsible for transmitting and receiving ultrasonic signal and sending the signal to the host. The master unit includes the MCU, LCD display circuit, Bluetooth communication module. It is responsible for data processing and display the results and controlling. The master and slave units transmit data via Bluetooth communication module. MSP430F microcontroller is used as systems main control unit and ROK101007 Bluetooth communication chip for wireless data transmission. The system can be used in dangerous environment such as high pressure or high temperature with a decrease of human security and other considerations. It has great application prospect.
