【摘要】 为了在震后能够及时获取大坝震动信息,以及远程管理的需要,研究并开发了大坝远程强震监测系统,并对各种通信方式进行了研究和应用。着重介绍其中一种基于公共交换电话网(PSTN)的大坝强震动远程监测系统通信协议的设计规则以及系统通信的线程设置。通过工作流程图以及系统的几组源代码,介绍了应用PSTN进行信息通信的关键技术。更多还原

【Abstract】 In order to obtain the dam’s motion imformation rapidly after an earthquake,and to meet the requirement of remote management,a remote strong earthquake observation system for dams is developed. Various modes of communication have been researched and applied in the system. In this paper,the communication protocol design based on public switched telephone network(PSTN) in the remote observation system and threads setting in the communication course of the system are introduced. The key technologies of communication based on the PSTN are introduced in detail through the flow charts and some program codes.更多还原
