摘　　要：为了适应中国数字强震动台网建设发展的需要,设计出了高精度三通道数字强震记录器,本文对该记录器作了简要介绍。高精度三通道数字强震记录器采用了高精度的Δ-∑类型的24位AD转换器,其有效转换位数达到17.5位。记录器支持本地串口通信、Modem远程拨号通信、TCP/IP网络通信等多种通信方式,仪器面板上有液晶屏、小键盘,直接支持自启动、参数设置等,并且实现了便携式低功耗设计方式,完全满足数字强震动监测网络建设发展的需求。One high resolution three-channel strong-motion recorder is designed for the development of China digital strong-motion observation network. In this paper, the recorder is introduced in detail. The recorder is designed with 24 bits analog-to-digital converter which is type of△-∑ converter, itst effective convert bit can achieve 17.5. And it supports local serial-port communication, remote modem dial communication and network communication of TCP/IP protocol. The recorder also supports LCD display and keyboard operation. Therefore it can be startup and modified parameters without computer. The low power consumption and portable design of the recorder make it suitable for the development of China digital strong motion observation network.
