嵌入式地震前兆观测仪器网络接口系统设计
|
摘要
针对"九五"期间地震前兆台站DSC系列公用数据采集器的工作状况及特点,研制出一种基于TCP/IP协议的嵌入式以太网通信接口设备——EP95型IP采集转换器。将"九五"地震前兆仪器的工作方式通过此接口设备转换成符合"十五"规范要求的各种方式,使其支持WEB和命令控制操作等,这样可方便数据中心的统一管理、数据资源共享和交换。
In the light of the characteristics and operational condition of the seismic precursor DSC data acquisition device at the "Ninth Five-Year Plan" period——an embedded ethernet communication interface equipment,the EP95 IP data acquisition device based on TCP/IP protocol is developed.The working mode of seismic precursor device at the "Ninth Five-Year Plan" period was transformed to the mode fitting the criterion for"Tenth Five-Year Plan",thus making it support WEB and command control and,finally,it will be convenient for unified management,data sharing and exchange.
