摘要

提出了一种基于无线网络的浅层地震勘探仪低功耗设计,重点讨论了检测子站的设计方案。该方案以AVR的AT32UC3B0256为核心,以低噪声、高分辨率模数转换器ADS1255实现数据采集,选用CC1101组建无线网络,实现了低功耗浅层地震勘探仪检测子站。针对模数转换器工作的间断特点,设计了可控电源模块,实现动态供电;利用CC1101的无线唤醒功能进一步降低了系统的待机功耗。测试表明,检测子站在测期间功耗约700mW、传输期间功耗约1 000mW、待机功耗约25mW。
A low-power shallow seismograph design based on wireless network is presented.This paper mainly discussed the design of shallow seismograph detection sub station.In the design,using AT32UC3B0256 as the center,with ADS1255 for analog to digital conversion,adopting CC1101 to build the wireless network,the shallow seismograph detection sub station is realized in low power consumption.For the intermittent characteristics of analog to digital converter,a controllable power supply module is designed to realize the dynamic power supply;using the CC1101 wireless waked-up function,the standby power consumption of system is reduced further.Test results show that the detection substation power consumption in detection is about 700 mW,power consumption in transmission is about 1 000 mW,and standby power consumption is about 25 mW.
