这是一种单片机控制的智能化抢答器,该抢答器可以克服普通抢答器存在的各种缺陷。详细介绍了其硬件结构和设计方法。本系统的功能是通过按下抢答键的按钮使单片机的相应的口线读入信号,经过处理后输出至7447显示所按下的键号。本系统还具备了用概率的方法筛选第一有效抢答信号、显示超前违规抢答信号、以及可变的提示抢答的倒计时信号和按键自检等功能。其中简述了单片机的特点和7447芯片的使用;概述中断系统的控制功能,并详细介绍了本系统软件的程序设计和步骤。-This is an intelligent microprocessor controlled Responder, the Responder Responder can overcome various problems common defects. Details of their hardware architecture and design. Functions of the system by pressing the key button to answer in the corresponding microcontroller port line read signal processed output to 7447 display the pressed key number. The system also has a way with the probability of selection and effective answer in the first signal that answer in advance violation signal, and the prompt answer in the variable countdown signals and key self-test functions. Which outlines the characteristics and the 7447 microcontroller chip use overview of the interrupt system control functions, and details of the system software, programming and procedures.
