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.
