基于CAN总线的大坝边坡安全监测模块设计

边坡监测是大坝安全监测的一个重要方面,边坡监测的自动化是一种必然的发展趋势。针对边坡监测的特点以及边坡监测常用的传感器的特点,设计了一种基于CAN总线控制系统的大坝边坡安全监测模块。该模块采用C8051f040作为CPU,AD620作为放大器,AD7710作为AD转换芯片,并进行了抗干扰、防雷击、防潮以及环境适应方面的设计。实验证明该模块测量精度能够满足水利系统的要求,而且具有长期稳定性,对环境的适应性等方面则有待该系统在青海拉西瓦大坝的现场实验中得到验证。

Design for the Slope-security Monitoring Module of Dam Based on CAN Bus

Slope monitoring is a important part for dam safety monitoring,and the automatic slope monitoring is necessary.Aim at the features of slope monitoring and the sensors used in slope monitoring,we design a slope-security monitoring module of dam based on CAN Bus-mastering system.The module takes C8051f040 as CPU,AD620 as amplifier and AD7710 as the AD converter chip,it also contains design of anti-jamming,preventing lightening and moisture and adaptation of environment.Experiment indicate the module can meet the requirements of the water system,and the performances as adaptation of environment will be certificated when used in the slope monitoring of Lasiwa Dam.
