摘要
为了保证数字遥测地震台网的地震监测和速报质量,在《地震观测技术规范》规定各遥测台站要每天(甚宽带要每月)定时进行脉冲标定,并每天检查脉冲标定的幅度和周期变化,当发现脉冲标定波形的周期发生明显变化或脉冲幅度变化>5%时,应及时检查修复。以前天津台网定时进行脉冲标定,但脉冲标定周期和幅度都是通过值班人员人工检测,并记录在值班日志上的方法进行检查的。现在我们编写了《脉冲标定自动检测软件》,软件每天能自动完成检测并将结果通过对话框的方式显示在微机上,使这项手工费时费力的检测工作变成抄表式操作。
To guarantee the quality of earthquake monitoring and speed report in digital remote network, it is required by Chapter 5 of Earthquake Observation Technology Criterion to scale the short period seismographs on a daily basis and the broad band seismographs on a monthly basis with pulse calibration. Moreover, it is compulsory to check the amplitude and period of pulse calibration, in case the amplitude and period of the pulse calibration waveform variance are bigger than 5%. Tianjin seismic network used to be scaled by pulse at regular time everyday, the period and amplitude of the pulse were measured manually, and were written in the duty log. Now we have developed Auto Detection Software of Pulse Scale, which can do auto detection everyday and demonstrate the result on the screen in the dialogue box. This converts the manual detection to table copying operation.
