基于无线数据采集技术的弹性波测量仪研制

Development of Elastic Wave Measuring Instrument Based on the Wireless Data Acquisition Technology

工程勘探环境的日益复杂带来了弹性波测量仪的数据采集与传输难题。采用高精度ADC设计数据采集单元,nRF无线收发集成芯片设计数据传输单元,实现弹性波测量仪的无线数据采集。仪器在"5.12汶川地震"某地质区域进行了地质勘探应用实验研究,找出了某处隐伏断层,结果表明:该成果打破了传统的有线数据采集方式,实现了便携式工程勘探,作业时间缩短到传统测量仪的1/3,具有较好应用前景。

With the increasing complexity of the engineering exploration circumstance, the elastic wave measuring instrument＇s data acquisition and transmission problems were brought about. Thus, the latest ADC （Analog to Digital Converter） with high precision was adopted to design the signal sampling element, and the nRF integrated wireless transceiver chip was used to form the data transmission unit. In one of the geological region of the ＂5.12Wenchuan Earthquake＂, the geological survey has been done with the instrument above and somewhere a hidden CT has been found. The above achievements show that the research has broken down the traditional fixed wire mode, realized the goal of portable exploration and shorten the operation time to the 1/3 of the traditional measurement. The project has a better prospect.
