分析比较了3种不同的密集架控制方案,提出了基于以太网和CAN总线的分布式控制系统结构。基于可靠性优先的主体思想,结合实际功能需求,给出了主站和从站控制器的主要硬件配置和实现原理。针对密集架系统存在的安全问题,提出了多传感器自主多层安全监测框架,并介绍了传感器的性能,明确了安全监控的层数,实现了自主安全监控的目的。同时,对现场CAN调试过程遇到的问题进行了分析总结。实验结果证明,该密集架控制系统及其安全监测系统具有操作简便、成本低廉、稳定可靠和自动安全防范措施完善等特点,该系统为智能仓储和物流管理系统的开发提供了一种参考。
Three different control schemes of shelves were analyzed and compared, and the structure of distributed control system based on Ethernet and CAN bus was proposed. Based on the main idea of reliability priority, combined with the actual functional requirements, the main hardware configuration and implementation principle of the master and slave controllers are given. Aiming at the safety problems of shelving system, a multi-sensor autonomous multi-layer safety monitoring framework is proposed. The performance of sensors is introduced. The number of safety monitoring layers is clarified and the purpose of autonomous safety monitoring is achieved. At the same time, the problems encountered in the on-site CAN debugging process are analyzed and summarized. The experimental results show that the system and its safety monitoring system are easy to operate, low cost, stable and reliable, and perfect automatic safety precautions. The system provides a reference for the development of intelligent warehousing and logistics management system.
