新增站体自动检测电路设计

The automatic detection circuit design for roll-in acquisition unit

地震仪器施工过程中,排列不断向前滚动,前端不断有新增站体加入。如果地面站体能够自动识别下级是否存在新增站体,并自动为新增站体加电,那么就能够大大提高仪器施工的效率。本文介绍了一种新增站体自动检测电路,通过将该检测电路加入到采集站和电源站中,测试某点的电压值,再将该电压值与预先设定的阀值比较,来判定排列中是否有新增站体,从而判定是否向外输出±24V的电压,最终实现自动识别有无新增站体、自动向新增站体提供电能的功能。

In seismic exploration process, with the rolling of seismic array, there are always new acquisition units to join. If the acquisition unit on the seismic array can automatically identify the existence of new additional stations and automatically plus power for them, then it can greatly enhance the efficiency of seisimc exploration equipments. This paper presents a new station additional automatically detect circuit.
