基于CAN总线的分布式电梯群控系统的研究与设计

应用多代理系统分布式求解问题的思想可构建分布式电梯群控系统，克服集中式电梯群控系统因实时性要求较高而出现的计算瓶颈，提出了基于合同网协商模式的分布式电梯群控系统MAS模型，分析了该群控系统中各实体对象与代理的映射关系，利用LPC2292开发板从硬件上构建了基于CAN总线的分布式电梯群控系统，并从软件上设计了其中的各个代理及分布式群控算法。

Design and Implementation of Distributive Elevator Group Control System Based On CAN Bus

The idea of distributive problem solving existed in Multi-Agent System is used to establish Distributive Elevator Group Control System （DEGCS）, which can eliminate the computing bottleneck caused by the real-time requirement of the EGCS. A DEGCS model of multi-agent based on the negotiation mode of contract net mechanism is introduced and mapping relationship among agents in the DEGCS model and the object entities of the EGCS. In hardware level, the DEGCS is constructed by development boards of LPC2292 （a type of micro-controller unit with ARM7TDMI-S core produced by Philips Ltd. ） that are connected by CAN Bus; in software level, all the agents of the DEGCS and the corresponding distributive algorithm of group control are designed and implemented.
