摘要
根据抢答的规则和流程分析了抢答器的控制要求和系统设计思想。以六路抢答器系统为例,采用PLC作为控制核心部件对LED数码显示的抢答器系统进行了设计,并着重探讨了系统的硬件选择、I/O分配和程序设计等关键环节。
According to the rules and processes of the rush responding, the control requirements and system design ideas of the responder are analyzed. With the six-way responder system as an example, using the PLC as the control core parts, the responder system with LED digital display is designed. The hardware selection, I / 0 allocation, program design and such key links are emphatically discussed in this paper.
