ADS1282及其在单通道地震数据采集单元中的应用
|
摘要
为满足高精度地震数据采集需要,设计一种以32位、高集成度模/数转换器ADS1282为核心,以高性能、低功耗微控制器MSP430F123为采集控制器的单通道地震数据采集单元,该单元可实现单通道地震信号的拾取、数据转换、存储及传输功能。设计中充分利用ADS1282片上集成功能,配合相应的抗干扰措施,既简化了电路设计,也保证了采集信号的质量和系统的稳定性。该采集单元可适用于那些对功耗、体积、精度均有严格要求的应用场合。
To meet the needs of high-precision seismic data acquisition,a single-channel seismic data acquisition unit was designed,which used the 32-bit high integration analog-to-digital ADS1282 as a core and the high-performance,low power microcontroller MSP430F123 as the acquisition controller.The unit achieved such functions: single-channel seismic signal signals picked up,data conversion,storage and transmission.The design unite fully used with the design ADS1282 chip integration,with the corresponding anti-jamming measures,not only simplified the circuit design,but also ensured the quality of signal acquisition and system stability.The acquisition unit is suitable for the application which have strict requirements in power,volume,precision.
