新型三级分布式大坝安全监测自动化数据采集装置

针对现有二级分布式安全监测自动化采集模块采集形式单一、扩展能力差、存储容量小、通道配置不灵活等弊端,笔者提出一种能适应各种类型监测仪器采集、测点接入数量不受限制的新型三级(监测中心层、测站层、采集层)分布式大坝安全监测自动化采集系统架构。重点介绍了该架构的核心部分——数据采集装置的工作原理、硬件构成以及电路实现。通过应用新型CAN总线通讯技术和SD卡大容量存储技术,使系统在通用性、扩展性、先进性和可靠性等方面都有很大提高。

Design of new three-level distributed dam safety monitoring automatic data acquisition device

The existing 2-level distributed safety monitoring automatic acquisition modules have some disadvantages,such as a single module only detecting one type of sensor,poor expansion ability,small storage capacity,and nonflexible way of channel configuration. This paper presents a new 3-level distributed architecture for dam Safety monitoring automatic acquisition system.It consists of monitoring center layer,station layer and acquisition layers,thus the data acquisition devices can detect various types of senso...
