超声波随钻井径检测仪的数据采集与传输

摘要

To make full use of the advantages of the authenticity and flexibility of data detected by logging while drilling tool, an exciting transducer is developed to collect, temporarily store and transmit the echo on FPGA minimum system board made in the laboratory, which is involved with AD data acquisition, FPGA data cache and FPGA data serial transmission of APA075 FPGA data collection and transmission system produced by Actel Inc.%　　为了更好地发挥随钻测井仪检测数据的真实性和使用灵活性等优点，文中基于Actel公司的APA075FPGA数据采集和传输系统所涉及到的AD数据采集、FPGA数据缓存、FPGA中数据的串口发送三部分，在实验室自制的一块FPGA最小系统板上，开发了一种激发换能器来对回波进行采集、缓存和传输。
