摘　　要：基于单片机AT89S53和RS-485总线设计和开发大坝安全监测数据采集系统,采用分布式结构及组网方式,通过安全监测自动化软件对整个大坝性态进行实时监控。重点研究了数据采集模块的工作原理、硬件构成,软件方面设计并实现了串口通信动态链接库(DLL)。该系统能有效实现大坝的远程通信和监控。The design of safety monitoring data collection system of dam based on mico-chip AT89S53 and RS-485 bus was introduced.It adopted a distributed architecture and networking method to monitor the status of the dam automatically through the safety monitoring software.And working principle,hardware structure of data collection module were studied with stress,then complicated the dynamic link library（DLL）of series-communication in software.This system is effective to the centralized monitoring and long-distance communications of dam.
