摘要
为了测量海底自然电场产生的微弱信号,提出一种基于STM32的海底自然电位法检测系统。该系统以微弱信号的检测为核心,采用仪表运放对微弱信号进行放大处理,经AD转换后传输给单片机,单片机将采集的数据进行处理后通过串口输出,可以方便地查看测量结果。经实验验证,可以在海底热液硫化物矿体勘探中得到成功应用。
To measure the electric field generated by Self-potential weak signals,we proposed STM32-based submarine Self-potential detection system.The weak signal detection plays the key role in the system,this system uses instrument op-amp for amplification treatment of weak signal,then transmits data to the microcontroller after AD transform,and the microcontroller outputs the collected data through a serial port.It is easy to view the measurement result.The experiments prove that the system can be successfully applied on hydrothermal sulfide ore exploration.
