本文以DFS-V数字地震仪、SSS-200、SSS-300和TBZ-800遥爆系统为例,讨论数字地震仪与遥爆系统的同步原理及爆炸信号的功能与意义,指出三种不同的时断信号(钟时断、验证时断和内部时断)启动仪器扫描时序对记录的影响,阐述了爆炸信号不是检验爆炸时刻与采集地震信号同步的充分必要条件。提出了应根据不同的方式和不同的遥爆系统来规定爆炸信号的误差。
Taking DFS-V digital seismograph, SSS-200, SSS-300 and TBZ-800 remote explosion system as an example, this paper discusses the synchronization principle of digital seismograph and explosive system and the function and significance of the explosion signal, and points out three different The influence of the time-delay signal (clock break, verify break and internal break) on the record of starting the instrument’s scanning sequence expounds that the explosion signal is not sufficient and necessary to test the synchronization of the explosion time with the acquisition of the seismic signal. It is proposed that the error of the explosion signal should be regulated according to different ways and different explosive explosion systems.
