爆破自记仪采用微控制器为核心的全CMOS集成电路,蓄电池供电以及遥控电源等的设计方案,测量不用导线和电源线。自记仪为单通道,带宽0～1000Hz,记录时间1S,由爆破同步信号启动记录,记录完毕自动断电。记录时首先记入同步信号,此同步信号在多台自记仪模拟输出的时间曲线上是对齐的;在数字输出时供计算机识别波形。模拟信号还原过程的尾部记有100Hz的矩形波供标定用。
Blasting self-record instrument uses a microcontroller as the core of all-CMOS integrated circuits, battery-powered and remote control power supply design, measurement without wires and power lines. Self-record instrument is a single channel, bandwidth 0 ~ 1000Hz, recording time 1S, recorded by the blasting synchronization signal start recording automatically power off. The first record of the synchronization signal is recorded, the synchronization signal in multiple self-recording device analog output time curve is aligned; digital output for the computer to identify the waveform. The end of the analog signal recovery process recorded a 100Hz square wave for calibration.
