基于单片机和PC端组态软件的多路抢答器研制

为解决现有各类抢答器所存在的抢答不公平、人机界面不友好等两大问题,可设计一种新型的智能抢答器,其采用单片机控制板做下位机、PC端组态软件做上位机的协调控制模式。一方面,利用单片机控制板的快速分辨能力,负责扫描按键,分析并锁定抢答数据,保证了抢答结果的准确;另一方面,又可利用PC端组态软件的友好操作界面,易编写出友好的抢答器人机界面。

Study on Multi-channel Responder based on Single-chip Microcomputer and PC Configuration Software

To solve two big problems--the unfairness existing in each kind of responder, unfriendly man- machine interface, it designs a new type of intelligent responder which uses a control mode of coordination between SCM control and PC configuration software control. On the one hand, the use of rapid resolution of MCU is responsible for the button scan, data analysis and guaranteeing the accuracy of the answers And on the other hand, the use of PC configuration software is easy to write a friendly responder man-machine interface. The effect of actual use of responder by two dozen college students is very good which prove that it has the very high popularization value.
