چکیده
Abstract In Fretting is an important research direction in the detection of urban underground space structure. Traditional geophones have three issues with achieving fretting field, high cost, large size and low accuracy. A signal acquisition system based on AD7177 proposed to solve above problems, which takes STM32 as design core. decision-making scheme that combines vibration sensor introduced, used settle cost instrument. To improve accuracy, high-precision A/D conversion module GPS are for processing positioning timing respectively. Finally, tests field experiments were conducted a state equipped storage WIFI transmission, shows convenient successful. The experimental results show effective, AD7177-based has accuracy small volume, good ability complete detection.

FPGA-Based Signal Acquisition System
This paper presents a high-performance four-channel signal acquisition system composed of frequency channelizers and signal detectors in a single 6U VME slot. The intense computational complexity necessary to implement such an application requires field programmable gate arrays (FPGAs) to achieve a 10x performance density increase over a traditional GPP implementation. The same application perf...
