DZW型重力仪自动调零装置的原理和设计
|
摘要
设计了一种新型自动调零装置的机械结构和电路结构,该结构不仅能将DZW型重力仪的调零精度提高到40×10-8m s-2,而且还能提高仪器调零速度和实现远程遥控调零,即可通过网络和控制软件实现远程对仪器调零,在调零过程中不产生过调整和欠调整情况。
The mechanical structure and circuits of a new type of automatic zeroing device are designed,which can make the precision of DZW-type gravimeters' zero conrol reach to 40×10-8ms-2.The design not only accelerates the zeroing operation but also avoids excess and lack of adjustment as well.Moreover,the device can fulfill automatic zero by distant control.
