爆破振动自记系统包括：①有线遥控装置；②无线电遥控装置；③串行数字通讯与微机配套；④自记仪。无线电遥控装置提供开机及同步信号，有线遥控提供同步信号，它们提供信号的可靠性在９５％以上。自记仪的工作受控于开机信号和同步信号。当不需要时间起始标记时，自记仪利用自启动完成振动波形的记录。几年来该系统已在十多个工地应用，工作正常，使用效果良好。串行数字通讯用ＲＳ－２３２标准，波特率用１２００，能正确地传输数据到终端ＰＣ机存盘。选用ＣＲＡＳ软件整理和分析观测资料，使成果质量更高，工效倍增。
Blasting Vibration self-recording system includes: ① wired remote control; ② radio remote control device; ③ serial digital communications and computer support; ④ self-record instrument. The radio remote controls provide power-on and synchronization signals, and wired remote control provides synchronization signals that provide over 95% signal reliability. Self-record instrument work is controlled by the boot signal and the synchronization signal. When you do not need time to start the mark, the self-charter uses self-starting to complete the recording of the vibration waveform. Over the past few years the system has been applied in more than a dozen sites, work properly, the use of good results. RS-232 serial digital communications standards, the baud rate with 1200, the correct data can be transmitted to the terminal PC save. The use of CRAS software sorting and analysis of observations, the results of higher quality, ergonomic doubled.
