一种新型微破裂信号并行采集电路的设计与实现
资料介绍
基于STM32微处理器,以CirrusLogic公司的CS3301A,CS5372A,CS5376A相组合,利用以太网传输技术,设计了一种新型微破裂信号并行采集电路.该电路主要由可编程增益放大器、24位△-∑A/D转换器、多功能数字滤波器组成,具有动态范围宽、信噪比高、道间串扰小,功耗低等优点.其采样率可在1-4ksps范围内可调.解决了单通道采集电路中存在的拾震能力不强、波形不全面等问题.野外测试表明该电路采集的波形很好,在微震监测中具有可靠的应用性.
Based on the STM32 microprocessor, to make Cirrus Logic＇ s CS3301A, CS5372A,CS5376Acombined, and using Ethernet transmission technology to design a new type micro burst signal collectioncircuit in parallel. The circuitmainly consists of a programmable gain amplifier, 24 A - EA / D converter, multi-function digital filter, it has a wide dynamic range,high signal to noise ratio,crosstalk between channels small andlow power consumption characteristics. The sampling rate can be adjusted within a range of 1 -4 ksps. to solve theproblems which are the capability of picking up shock is not strong and the waveform is not comprehensive in single-channel. Field tests show that the circuit can acquire good waveforms, and ...
