| 中文摘要 | Dynamic lung sound signal analysis and processing require synchronous multi-channel data acquisition system. In noninvasive and no pain lung sound diagnosis system, the highly accurate, synchronous and stable data acquisition system is the foundation of fellow-up work. In order to acquire the array data of lung sound, higher speed, reliability and synchronous data acquisition system can meet the requests. Lung sound signal was produced by lung vibration during air exchange. Simultaneous sampling maintains the phase information and provides us with more detailed information about physiology and pathology. Our method is to use piezopolymer sensor array attached to the backside and capture the lung vibration information. This paper mainly presents a FPGA-based synchronous data acquisition system. FPGA as a main component offers the ADC chip timing and FIFO design using Verilog HDL source code. Furthermore, this paper solves the synchronization problems so that array phase information is saved. Test results of the data acquisition system can fully meet the need of data acquisition in array data acquisition of lung sound. © 2012 IEEE. |
