摘要
本文设计一套基于AT89C55,嵌入式系统UCOS-II以及RS485总线的酒店客房控制管理系统。在硬件设计方面,详细研究了以AT89C55为核心,详细研究通信子系统、数字量输入系统、数字量输出系统、二通阀调节系统的设计方案和实现原理。在软件设计方面,以UCOS-II为操作,根据各系统的各功能部分的实现任务规划,并根据其重要性和执行率的高低分配任务的优先级。通过验证,该系统的各功能子系统均能良好运作,系统软硬件设计方案可行。
This dissertation designed a system based on AT89C55, embedded systems UCOS-II and the RS485-bus, hotel rooms control and management system. In hardware design, it conducted a detailed study on AT89C55 as the core, and communication subsystems, digital entry systems, digital output system, the second valve adjustment system design and implementation principle. In software design, use UCOS-II for the operation, according to parts of the system to achieve the various functions of mission planning, and implementation rate in accordance with their level of importance and priority allocation of tasks. After validated, the system can work well in all functional subsystems, the system software and hardware design is feasible.
