基于FPGA的大地震前兆传感信号采集模块
Sensor Signal Acquisition Model of Violent Earthquake Precursor Based on FPGA
摘要
Abstract
The formation and occurring of violent earthquake is a process of energy gathering and emission. During this process,it emits strong precursor. A sensor signal acquisition model of comprehensive monitoring system of microscopic precursors is proposed. It is com-posed of multi-signal acquisition,data reading,data packaging&sending,transfer management and generation model of clock and enable signal. The circuit of signal acquisition includes acceleration acquisition,temperature acquisition,geo-sound acquisition and electromag-netic radiation acquisition. There are four parts in the acquisition of geo-sound and electromagnetic radiation,and they are interface cir-cuit,filters,write memories and memories. The function of sensor signal acquisition model is implemented on FPGA which is faster and e-nough to handle large amounts of multi-channel sensor signal data. The adaptability and the high stability enable the system to maintain long-term normal working in the ground and other more hostile environment. In addition,it is easier to debug and update software which simplifies the development process and shortens the development cycle.关键词
