在日本东北大学NECPC98系列微机地震波实时处理软件的基础上,成功开发了IBMPC机型上的地震波实时处理系统,并实际应用于成都遥测地震台网。该系统的技术优势主要在于用AR模型对信号进行预处理以压制干扰,提高信噪比,增加系统的稳定性和可靠性;采用赤池(Akaike)情报量规准则(AIC)对P波、S波进行自动判读,大大降低了误判率;其人机交互处理采用了鼠标器对波形进行截取、放大及P波、S波进行人工读取,提高了系统效率
Based on the real-time processing software of NECPC98 series computerized seismic waves of Northeastern University in Japan, the real-time seismic wave processing system on the IBMPC model has been successfully developed and applied to Chengdu telemetry seismic network. The main advantage of the system lies in the preprocessing of signals by AR model to suppress the interference, improve the signal-to-noise ratio and increase the stability and reliability of the system. Using Akaike’s intelligence rules (AIC) Automatic interpretation, greatly reducing the false positive rate; its human-computer interaction using a mouse to capture the waveform interception, amplification and P wave, S wave artificial read, improve system efficiency
