摘要

基于分布式瞬变电磁探测的分布式测量需求,结合MSP430信号处理芯片、ZigBee无线收发技术和GPS同步技术,设计并实现了24位分布式瞬变电磁的接收系统。该系统的接收机呈阵列式排布,各接收机所采数据的预处理都在MSP430中实现,数据可实现本地存储与上位机存储两种模式。接收机的采样率最高为200 kS/s,动态范围达到140 dB.试验证实了该系统的接收机可以准确检测出异常体,满足了分布式电磁探测的需求。
Based on distributed transient electromagnetic measurement needs,combined with MSP430 signal processing chip,ZigBee wireless transceiver and GPS synchronization technology,this paper designed the 24-bit distributed transient electromagnetic receiver system.The receiver was arranged in array type,data were preprocessing by MSP430 in each receiver.The data storage has two modes,local storage and computer storage.Receiver's sampling rate is up to 200 kS/s,the dynamic range is 140 dB.The experiments confirm that the receiver of the system can accurately detect the presence of abnormal body which meets the needs of distributed electromagnetic exploration.
