背景技术Background technique
天然源地震探测是指将节点式地震仪按照一定的拓扑结构排列，采集天然震源引起的地震波数据，并根据记录的地震波数据及拓扑结构，按照一定的算法进行计算，反演地质结构的一种方法。Natural source seismic exploration is a method of arranging node seismographs according to a certain topological structure, collecting seismic wave data caused by natural seismic sources, and calculating according to a certain algorithm according to the recorded seismic wave data and topological structure to invert the geological structure. method.
现有的天然源地震仪绝大部分是盲采，即在进行微动作业时地震仪先把采集到的地震波数据存储在本地，等作业完成后统一数据回收，导致无法实时确认采集数据是否成功以及数据质量，增加作业的不确定性。Most of the existing natural source seismographs are blind collection, that is, when performing micro-motion operations, the seismograph first stores the collected seismic wave data locally, and the data is recovered after the operation is completed, which makes it impossible to confirm whether the collected data is successful in real time As well as data quality, increase the uncertainty of the operation.
极少数的天然源地震仪支持3G或者wifi无线传输数据，但仅可无线回收数据，无法实时给出数据处理结果，导致无法实时获得现场作业效果。更无法根据地震波数据质量进行采样参数的自主调整，需要施工人员根据经验设置，降低作业质量。A very small number of natural source seismometers support 3G or wifi wireless data transmission, but they can only recover data wirelessly, and cannot provide real-time data processing results, resulting in the inability to obtain real-time results of field operations. It is also impossible to independently adjust sampling parameters based on the quality of seismic wave data, and construction personnel are required to set up based on experience to reduce the quality of work.

The attached drawings are for reference and explanation purposes only, and are not used to limit the protection scope of the present invention.
如图1所示，本实施例公开了一种基于无线通讯的地震探测方法，其将地震仪采集到的地震波数据经无线传输至上位机，上位机对地震波数据进行处理的过程包括如下步骤S1至S4：As shown in Figure 1, this embodiment discloses a seismic detection method based on wireless communication, which wirelessly transmits seismic wave data collected by a seismograph to a host computer. The process of processing the seismic wave data by the host computer includes the following steps S1 To S4:
S1、通过无线通讯远程接收台阵采集站采集的地震波数据，其中，台阵采集站按照初始采样参数对地震波数据进行采集；S1. Remotely receive the seismic wave data collected by the array acquisition station through wireless communication, where the array acquisition station collects the seismic wave data according to the initial sampling parameters;
其中，台阵采集站由n个地震仪按照设定的拓扑结构布置得到，该拓扑结构可为L形或圆形。初始采样参数为地震仪上电后的默认采样参数，比如初始采样率500bps，增益0db，滤波类型为sinc。Among them, the array acquisition station is obtained by arranging n seismographs according to the set topology, and the topology can be L-shaped or circular. The initial sampling parameters are the default sampling parameters after the seismograph is powered on. For example, the initial sampling rate is 500bps, the gain is 0db, and the filter type is sinc.
S2、对接收到的地震波数据进行处理，以对地震波数据质量进行评价；S2. Process the received seismic wave data to evaluate the quality of seismic wave data;
S3、根据地震波数据质量评价结果，对所述初始采样参数进行调整，得到调整后的采样参数；S3. Adjust the initial sampling parameters according to the seismic wave data quality evaluation results to obtain adjusted sampling parameters;
S4、将调整后的采样参数下发至所述台阵采集站以使台阵采集站按照调整后的采样参数对地震波数据进行采集。S4. Send the adjusted sampling parameters to the array acquisition station so that the array acquisition station collects seismic wave data according to the adjusted sampling parameters.
其中，利用无线地震仪按照初始采样参数实时采集地震波数据并将采集到的地震波数据通过无线传输方式发送至上位机，上位机对地震波数据进行处理，得到信号幅度、频谱混叠情况、频散曲线等，以对采集到的地震波数据进行质量评价，然后根据地震波数据质量评价结果对初始采样参数进行自主调整，直至使得地震仪采集到的地震波数据质量最优，提高作业质量。Among them, a wireless seismograph is used to collect seismic wave data in real time according to the initial sampling parameters and send the collected seismic wave data to the upper computer through wireless transmission. The upper computer processes the seismic wave data to obtain the signal amplitude, spectrum aliasing situation, and dispersion curve In order to evaluate the quality of the collected seismic wave data, and then independently adjust the initial sampling parameters according to the results of the seismic wave data quality evaluation, until the quality of the seismic wave data collected by the seismograph is optimized and the operation quality is improved.
优选地，所述初始采样参数包括采样率、采样增益、滤波参数和台阵采集站位置，所述根据地震波数据质量评价结果，对所述初始采样参数进行调整，得到调整后的采样参数，包括：Preferably, the initial sampling parameters include sampling rate, sampling gain, filtering parameters, and array acquisition station location. According to the seismic wave data quality evaluation result, adjusting the initial sampling parameters to obtain the adjusted sampling parameters includes :
（1）根据信号幅度与满量程的比值，对采样增益进行调整：(1) Adjust the sampling gain according to the ratio of signal amplitude to full scale:
具体地，本实施例中满量程为2500mv，若信号最大值小于100mv，增益加一倍，若信号最大值大于1000mv，增益减小一倍。Specifically, the full scale in this embodiment is 2500 mv, if the maximum signal is less than 100 mv, the gain is doubled, and if the maximum signal is greater than 1000 mv, the gain is doubled.
（2）根据频谱混叠情况对采样率进行调整：(2) Adjust the sampling rate according to the spectrum aliasing situation:
具体地，在实际应用中，采样率越大，白噪声越大（干扰越大），出现频谱混叠的信号频率越大（带宽越大），数据量越大（数据处理压力越大）。在满足关注的频率最大信号采样不失真情况下，采样率越小越好。Specifically, in practical applications, the greater the sampling rate, the greater the white noise (the greater the interference), the greater the frequency of the signal with spectrum aliasing (the greater the bandwidth), and the greater the amount of data (the greater the data processing pressure). Under the condition that the maximum signal sampling at the frequency of concern is not distorted, the smaller the sampling rate, the better.
（3）根据实时频散曲线能量集中效果，对台阵采集站位置进行调整。(3) According to the energy concentration effect of the real-time dispersion curve, adjust the position of the array acquisition station.
具体地，若频散曲线高频部分能量不强，减小台阵半径，频散曲线低频部分能量不强，增加台阵半径。Specifically, if the energy of the high frequency part of the dispersion curve is not strong, reduce the radius of the array, and if the energy of the low frequency part of the dispersion curve is not strong, increase the radius of the array.
（4）根据干扰情况对滤波参数进行调整。(4) Adjust the filtering parameters according to the interference situation.
具体地，根据频谱图，计算干扰较大的频率，设定滤波类型是高通、低通、带通，根据干扰频率，设置截止频率。Specifically, according to the spectrogram, calculate the frequency with greater interference, set the filter type to be high pass, low pass, and band pass, and set the cutoff frequency according to the interference frequency.
需要说明的是，采样参数经过调整后，若经过设定时间够，采样参数不再改变，则记录此时参数，此次作业过程中不再进行参数调整，以保证采样参数的一致性。It should be noted that after the sampling parameters are adjusted, if the set time is sufficient and the sampling parameters no longer change, the parameters at this time will be recorded, and no parameter adjustments will be made during this operation to ensure the consistency of the sampling parameters.
优选地，在所述通过无线通讯远程接收台阵采集站采集的地震波数据之后，还包括：Preferably, after said remotely receiving the seismic wave data collected by the array acquisition station through wireless communication, the method further includes:

根据所述台阵采集站的拓扑结构和面波频散曲线，将当前算法自动改变为FK算法或SPAC算法。According to the topology structure and surface wave dispersion curve of the array acquisition station, the current algorithm is automatically changed to the FK algorithm or the SPAC algorithm.
具体地，若是拓扑结构为L型则优先选择FK法，若是拓扑结构为圆形则优先选择SPAC法。频散曲线如果深层效果不好就采用FK法，若频散曲线低频部分不连续或者无低频频散曲线，则说明浅层频散曲线品质不高，则需采用SPAC法。Specifically, if the topology is L-shaped, the FK method is preferred, and if the topology is circular, the SPAC method is preferred. If the deep effect of the dispersion curve is not good, use the FK method. If the low-frequency part of the dispersion curve is discontinuous or there is no low-frequency dispersion curve, it means that the quality of the shallow dispersion curve is not high, and the SPAC method is required.
优选地，还包括：根据预先设置的刷新频率将所述第一无线通信模块发送的地震波数据实时绘制成地震波形。其中：在具体处理过程中如果数据量过大超过用户设置的刷新频率，则需要对数据进行部分丢弃，如间隔丢弃（奇数数据点丢弃）。Preferably, the method further includes: real-time drawing the seismic wave data sent by the first wireless communication module into a seismic waveform according to a preset refresh frequency. Among them: In the specific processing process, if the amount of data is too large and exceeds the refresh frequency set by the user, the data needs to be partially discarded, such as interval discarding (odd data point discarding).
优选地，还包括：将绘制的地震波形和提取到的面波频散曲线进行显示，以向客户展示作业效果。Preferably, the method further includes: displaying the drawn seismic waveform and the extracted surface wave dispersion curve to show the work effect to the customer.
优选地，还包括：将地震仪经无线传输后的地震波数据按照设定的格式储存，以便客户回收数据。本实施例中：一个站上传数据包含有帧头信息和3个地震检波器的10个采样点的采集数据，数据格式是按照上位机软件处理数据时规定的格式协议。Preferably, it further includes: storing the seismic wave data after the seismograph is wirelessly transmitted in a set format so that the customer can retrieve the data.
