| 中文摘要 | 针对大规模分布地震检波器的现场测试需求,本文设计了一种基于手持PDA的检波器测试系统.该系统利用FPGA芯片和Cirrus Logic公司的地震套片对检波器进行激励和信号采集,通过RS232串口与PDA进行通讯,接收PDA的控制指令并将采集到的数据发送给PDA。利用LabVIEW for Pocket PC Modul编写的应用程序运行于PDA的Windows Mobile操作系统,可以将测试的结果显示在PDA的屏幕上。结合LabVIEW的图形编程和信号处理的功能,该手持式测试设备具有强大的现场测试功能,而且有友好的人机交互界面。系统可以方便地从FPGA接收数据,并在PDA中进行处理和显示,不仅体积小,功耗低,而且功能强大,工作效率高.; In order to fulfill the requirement of testing large-scale distributed seismic detectors,a testing system based on a portable PDA was designed in this paper.A seismic exploration chip suit and a FPGA chip were used to give excitation and collect the response signal.The system transmitted processed data to the PDA through a serial port.The controlling order was also transmitted from the PDA to the FPGA chip through the serial port. Users could see their testing results on the screen of PDA which is programmed by LabVIEWfor Pocket PC module,operating under Windows Mobile OS.With graphics programming function and signal processing abilities of LabVIEW,the handheld device is considered to be a powerful field-testing instrument,especially containing a friendly interface.It proves convenient to receive raw data by FPGA,then to process and display testing results on PDA,which leads to certain advantages including small volume,low power consumption, high efficiency and so on. |
