高精度三通道强震动地震记录仪硬件设计

Hardware Design of High Precise Strong Seismic Motion Recorder with Three Channels

本文详细介绍应用24bits AD实现的高精度三通道强震记录仪硬件设计原理及整体设计过程。24bits AD本身动态范围能实现100 d B以上的,特别实用于地震台网中无人值守的三通道强震动记录仪,系统硬件的稳定可靠、技术的先进等诸多优势,可以实现对天然强震动的有效记录。

In this paper, the whole design process and hardware design principle of three-channel recorder with high precision are introduced in detail and the application of 24 bits-AD is also achieved. Dynamic range of 24 bits-AD can achieve more than 100 d B, especially practical three channel on unmanned seismic network on strong motion recorder, the hardware of the system is stable and reliable, advanced technology and other advantages, can effectively record the vibration of the natural strong earthquake.
