PLC 实训( 四人智力抢答器) 编号: PLC 应用实训说明书题目: 四人智力抢答器院(系): 专业:机械设计制造及其自动化学生姓名: 学号: 指导教师: 2013 年1月6日桂林电子科技大学实训报告用纸摘要抢答器在竞赛中有很大用处, 它能准确、公正、直观地判断出第 1 抢答者。通过抢答器的指示灯显示、数码显示和警示蜂鸣等手段指示出第 1抢答者。本文介绍一种数字式抢答器的设计方案, 其程序设计简单, 通过 PLC 的梯形图设计完成, 利用 GX Developer 软件编辑程序, 仿真验证, 非常适用于多种竞赛场合。通过实训促进学生对可编程控制器的工作原理、结构组成、指令系统的理解掌握, 并学会简单的程序设计与系统调试方法, 进而提高可编程控制器的编程水平和应用能力, 为以后的学习、工作打下坚实的基础。关键词: PLC ;抢答器;定时功能桂林电子科技大学实训报告用纸 Abstrac Responder in petition is very useful, it can be accurate, impartial, intuitive to judge from first responder. The responder indicating lamp display, digital display and warning buzzer and other means to indicate first responder. This paper introduces a digital answering device design, the program design is simple, through the PLC ladder diagram design, use GX Developer software to edit program, simulation, very suitable for a variety petitions. Through the training to promote students to the programmable controller the working principle, structure, instruction system of understanding, and learn simple program design and system debugging method, and to improve the level of programming a programmable controller and application ability, for the future study, work and lay a solid foundation.
