摘要
介绍了一种基于可编程控制器 (PLC)的分布式堤防安全监测数据采集系统的构成及工作原理 .该系统具有较好的扩展性、可靠性以及很强的抗干扰能力 ,同时解决了系统的后备电源、系统防雷等技术关键 。
The structure and operation principle of a distributed data acquisition system for embankment safety monitoring based on PLC, are introduced. The system has many merits such as high reliability, expansibility and anti_jamming. Moreover, the key technical problems in this system such as lightning protection and backup supply are also discussed. A good foundation is laid for embankment safety monitoring and warning in advance.
