摘 要
    本文采用西门子S7-200系列PLC进行路抢答器系统的设计，抢答器是一种能使任何比赛及竞争性的游戏体现公平、公正的电子装备。在比赛中为了准确、公正、直观地判断出第一抢答者，所设计的抢答器通常由数码显示、灯光、音响等多种手段指示出第一抢答者。同时，系统控制程序采用梯形图设计，并能有序地完成整个系统的自动控制，具有运行可靠，降低生产成本、提高生产效率等优点。
关键词: 抢答器 数码显示 自动控制 PLC

Abstract
 This article uses Simens S7-200 series PLC to enter travels vies to answer first system's design, vies to answer first is one kind can cause any competition and the competitive game manifests fairly, the fair electronic equipment. In competition, for accurate, fair, judges the first viing to answer first intuitively, designs vies to answer first usually by the numerical code demonstrated that the light, the sound and so on many kinds of methods instruct the first viing to answer first. At the same time, the systems control procedure uses the trapezoidal chart design, and can the order complete overall system's automatic control, has the movement to be reliable, reduces merits and so on production cost, enhancement production efficiency.
 key word: Vies to answer first digital demonstration automatic control PLC
