1.YBJ—1型爆破振动自记仪的性能与特点爆破振动自记仪测量是将传感器、记录器一起放在测点处,人员撤离现场时将自记仪置于等待状态。起爆前,遥控开机,记录与起爆合闸同步,记录完毕由软件自动关闭电源。也可以用自控方式。数据存储器具有掉电保护,存入的信号不会丢失。爆破振动自记仪由模拟放大单元、数据采集单元、数模转换及低通滤波单元、电源控制单元、爆破同步单元五部分组成。以微控制器执行EPROM中的程序工作,由小型镉镍蓄电池供电。爆破振动自记仪设计新颖,采用嵌入式微控制器为核心的全CMOS集成电路,使仪器能
1.YBJ-1 blasting vibration self-recording instrument performance and characteristics of blasting vibrometer measurement is the sensor, the recorder together at the measuring point, leaving the scene will be self-record instrument placed in wait state. Before detonating, the remote control is switched on and the recording and initiating switch-on are synchronized. After the recording is finished, the software automatically turns off the power supply. You can also use self-control method. Data memory with power-down protection, stored signal will not be lost. Blasting vibration self-recording instrument consists of five parts: analog amplification unit, data acquisition unit, digital-analog conversion and low-pass filter unit, power control unit and burst unit. Program execution in the EPROM with a microcontroller powered by a small cadmium-nickel battery. Blasting vibrometer design novel, using embedded microcontrollers as the core of all-CMOS integrated circuits, the instrument can
