| 摘 要： | 设计了一款采用ARM2440作为服务器主控芯片的排队系统,集成了基于ARM2440的开发板micro2440服务器、LPC2138型LED显示屏、基于AT89C2051的智能呼叫终端模块和语音呼叫模块。排队系统主要以时间作为优先级,主机根据服务类别形成队列,管理者可优先处理紧急事务。采用自制RS485总线通信协议传输信号,对信号进行循环冗余码检验,安全高效。以嵌入式操作系统RedhatLinux9.0作为主机服务器的开发平台,采用基于中断处理的前后台系统实现了LED显示屏和智能呼叫终端的软件设计。系统测试显示,各模块工作正常,满足设计的要求。

| Abstract: | A queuing system based on ARM2440 as a host server chip is introduced.ARM2440-based development board micro2440 server,LED display based on LPC2138,intelligent call terminal module based on AT89C2051 and voice calls module are integrated effectively.Queuing system looks time as the main priority.the host forms the queue according to type of service and the urgency.System uses self-made RS485 bus communication protocol signals.The protocol is developed to check the signal with cyclic redundancy code,which ensures system security.Redhat Linux 9.0 embedded operating system development platforms as the host server.LED display and intelligent call terminal software are used after the Taiwan-based interrupt handling system.System test shows that the module is working to meet the design requirements. |
