【摘要】 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，提高了系统效率更多还原

【Abstract】 On the base of the software compiled by Tohoku University of Japan for NEC PC 98 micricomputer series, we mprove it and make it appliable for IBM micocomputer series used in Chengdu Telemetry Seismic Network (CTSN). The technical advantages of this system are following aspects: Pre process the signals using AR model to suppress the disturbance, maximize the S/N ratio and make the system more stable and reliable; identify and pick up P or S arrivals automatically using the technique of Akaike′s Information Criteria(AIC), so the probability of the failure or mistake of event detection is reduced greatly; this system can also achieve the manual computer processing. With a mouse, we can zoom out and truncate the waveform and pick up P or S arrivals artificially, so the efficiency of this system is then improved.更多还原
