数字强震动台网远程光纤通信方案及其应用
|
摘要
经济、高效、稳定的通信技术是强震观测和地震工程研究的重要基石,将光纤通信技术应用于数字强震动台网,是对强震仪现有通信方式的改进和完善,它既可以独立成网,也可以接入国际互联网。本文详细研究各种类型强震仪的通信接口,将远程光纤通信分为基于RS-232串口和基于RJ-45以太网口两个方案,其方法是通过不同型号的光电转换设备和光纤将强震仪和计算机连接起来,它具有保证数据可靠性、完整性和避免强震仪通信引雷等诸多优点。
Economic,efficient and stable communication technology is an important cornerstone of strong motion and earthquake engineering research.The optical fiber communication technology used in digital strong motion station network improves and perfects the strong motion seismograph existing communication,either separate network, you can also access the Internet.The detailed study of various types of strong motion seismograph communication interface and the remote optical fiber communication is divided into two programs based on the RS-232 serial port and RJ-45 Ethernet port.The method is that strong motion seismograph and computers are connected together by different models of photoelectric conversion apparatus and optical fiber.
