爆破测振仪L20-N记录参数设置
记录参数为系统设置内第一个参数。
一、记录参数的设定原则
根据操作者使用习惯和振源类型选择触发方式;
触发电平值应大于测点环境的振动值(不自动触发);
记录时长应大于振动信号持续时间1-2秒;
时间触发常用在连续振动事件中采集定时定量的数据;
针对初学者,推荐选用波形触发方式;
二、记录参数设定步骤
1.触发方式
选择电平触发时需根据爆破参数,传播介质等因素设定触发电平和存储时长;
选择波形触发时,仪器根据测点环境自适应,无需任何设置;
选择时间触发时,仪器按照指定的时刻触发,在每个触发间隔内存储指定时长数据;
2.触发电平
触发电平只在触发方式为电平触发时需要设置;
触发电平过高,仪器不记录,触发电平过低,仪器误触发;
实际运用时选用不自动触发的最低触发电平值;推荐0.05cm/s
3.存储时长
存储时长只在触发方式为电平触发时需要设置;
记录时长过短,同一次振动事件会被分段记录;
设定的记录时长应大于整个振动事件持续的时间2s;
4.触发间隔
触发间隔是时间触发模式下的参数,设定的触发间隔必须大于存储时长,否则会导致时间触发模式无效;
5.
触发时刻
触发时刻是时间触发模式下的参数,触发时刻为将来任意时间点。
