摘　　要：针对滑坡灾害演化过程建模的高实时性能要求,推出一种基于云平台虚拟化的结构化分布式实时数据库系统。利用对等网络广播方式速度快、不需要服务器,客户机服务器查询方式完整、准确的特点,该系统将两者相结合,分别处理系统需要快速主动传递的实时采集数据或控制、处理操作等发生时的实时数据改变值。滑坡监测系统的应用实例表明,采用该实时数据库系统可较好地解决实时数据采集、处理、传输、控制等过程中的同步性、可靠性和一致性问题。According to the high real-time performance requirements of the evolution process modeling of landslide hazards,a kind of structured distributed real-time database system based on cloud platform virtualization is presented.This system synthesizes the advantages both the P2 P mode with no server and quick broadcast of information,and the C/S mode with complete and accurate query features,so it can separately process each kind of real-time data change values that need to be fast actively transmitted from real-time acquisition data or control and processing operations,etc.The application practice shows that the landslide monitoring system with this real-time database system can better solve the problems of synchronization,reliability and consistency in the process of real-time data acquisition,processing,transmission and control.
