摘　　要：采用传统方法对微地震电磁信号实施监测控制时所用的时间较长,且监控到的微地震电磁信号幅度曲线与实际幅度曲线之间的误差较大。为此,论文提出了基于单片机和超声传感的微地震电磁信号远程监测控制方法。该方法利用电源模块、NRF2401无线模块、时钟模块和超声液位传感监测模块组建单片机和超声传感单元,并采集微地震电磁信号。根据相邻道地震信号间的相关性,对微地震电磁信号做相关性运算,去除微地震电磁信号中存在的噪声,有效提高监测准确度。由于其他地震波与直达波的性质存在差异,为此,该研究在分离直达波的基础上,重建震源激发信号,从而实现对微地震电磁信号的远程监控。根据仿真结果可知:该方法的监控效率和准确度均较高。It takes a long time to implement the monitoring and control of the microseismic electromagnetic signal by the traditional method,and the error between the monitored amplitude curve and the actual amplitude curve is large.In this paper,a remote monitoring and control method of microseismic electromagnetic signal based on microcontroller and ultrasonic sensing is proposed.In this method,the power module,NRF2401 wireless module,clock module and ultrasonic level sensing monitoring module were used to build a single chip microcomputer and ultrasonic sensing unit,and the microseismic electromagnetic signal was collected.According to the correlation between the seismic signals of adjacent channels,the correlation calculation of the microseismic electromagnetic signals is done to remove the noise in the microseismic electromagnetic signals and effectively improve the monitoring accuracy.Due to the different properties of other seismic waves and direct waves,this study reconstructed the source excitation signal on the basis of the separation of direct waves,so as to realize the remote monitoring of the microseismic electromagnetic signal.According to the simulation results,the monitoring efficiency and accuracy of this method are high.
