摘要

在海底金属硫化物的探测过程中,发送机探测方法的选择对探测效果有着重要的影响。基于海洋激发极化方法设计了一套海洋双频激电发送系统。该系统能够根据甲板机发送的指令自动调整高低两种频率的大小,同时对发送系统中实时检测的电流、电压、水深等信号通过隔离差分传输方式进行有效的传送。最后,给出了相应的实验数据和结果分析,实验结果表明,该发送系统设计合理,为利用海洋激发极化方法进行海洋探矿提供了一个有益的尝试。
        In the process of submarine detection for metal sulfides,an electric transmitter system has a significant impact on detection effects.A transmitter system is designed based on the marine induced polarization method.The system can adjust the value of dual frequency automatically according to the instruction from deck machines,meanwhile it can transmit the signals of current,voltage and depth of water with isolated differential transmission in real-time.Finally,the corresponding experiment data and analysis results are given,in which the results confirm the rationality of the system.It is concluded that it is an useful attempt for the application that uses induced polarization method for marine prospecting.
