摘　　要：结合上位计算机和下位PC104嵌入式控制器,实现一种以PC104为核心的时序控制系统设计。在该设计中,下位PC104嵌入式控制器以黑箱模式工作,完成实时性要求较高的时序控制任务,上位计算机经由以太网与控制器进行通信,完成整个系统的远程监控。应用结果表明,该系统具有实时性高、可靠性高、配置灵活、功能重构性强的特点,能为各子系统提供安全可靠的时序控制。This paper implements a design of time-sequence control system based on PC104 by using below PC104 embedded controller in combination with an upper industrial computer. In the design, PC104 controller works black-box mode to finish the time-sequence task which has higher real-time demand. Ethernet communication is applied between the upper computer and the PC 104 controller, and remote monitor is achieved by the upper computer. Application results show that this system has the features of high reliability, high real-time, flexible configuration and strong function restructure, and it can provide reliable time-sequence control for sub-system.
