The Design of Distributed Monitoring and early-warning System Based on CAN Bus
针对目前岩土工程所用监测系统的实时性差、可靠性低的问题,提出基于低功耗处理器LPC1768与CAN(Controller Area Network)总线通讯相结合的分布式监测系统。通过设计智能节点对岩土工程的稳定性进行实时监测,获得其状态参数值；基于粒子群算法建立预测模型,对坝体浸润线高度进行预测。将该系统应用在坝体监测工程中,结果表明：该系统稳定可靠,预测精度较高,满足工程要求。
英文摘要:
In view of the poor real-time and low reliability of the monitoring system used in geotechnical engineering, a distributed monitoring system based on the low power consumption processor LPC1768 and CAN(Controller Area Network) bus communication is proposed. The intelligent nodes are designed. And the stability of geotechnical engineering is monitored in real time. The state parameters are obtained. The prediction model is established based on Particle Swarm Optimization (PSO) to predict the height of saturated line of dam. The system is applied in monitoring engineering. And the result shows that the system is stable, reliable and processing high prediction accuracy. And the engineering requirements are met.
