【摘要】 针对地震波高动态范围的特点,设计一种基于STM32和LabVIEW的24位高精度、120 dB高动态范围的地震数据采集卡。采集卡前端通过采用基于△-Σ技术的24位ADC调制芯片CS5372,配合使用数字滤波芯片CS5376,实现较强的数据采集和处理能力。选用STM32作为主控制器,使采集卡拥有低功耗以及高可靠性和可维护性。上位机采用LabVIEW作为开发平台,通过网络接口芯片ENC28J60实现STM32和上位机的通信。更多还原

【Abstract】 According to the seismic wave high dynamic range characteristics,a kind of seismic data acquisition card based on STM32 and LabVIEW for 24 bits high precision and 120 dB high dynamic range is designed.At the front of this acquisition system a 24 bits ADC modulation chip based on △-Σ technology CS5372 is used,and cooperates with using digital filter chip CS5376 realizing the strong data acquisition and processing power.STM32 is used as the main controller,which makes collection card has low power consumption,high reliability and maintainability.The upper machine used LabVIEW as a development platform,which through the network interface implementation STM32 and PC communications.更多还原
