摘　　要：提出抢答器,早期抢答器逻辑电路通常选用优先权编码器控制,逻辑功能单一,整体电路较复杂且其可靠性不高,需要缓冲时间较长,不便于后期功能扩展和升级。本系统通过对比最终选择FX2N系列PLC来实现,它的控制性能稳定,反应迅速,而且后期维修起来也方便,本文完成外围的硬件电路设计调试。This paper introduces the responder at first. The priority encoder is usually to be selected to control the logic circuit of initial responder, so its operation speed is slow, the circuit is complexity and the reliability is not high, the logical function is relatively simple. By comparison, the final choice is to achieve the system with Mitsubishi FX2N Series PLC, which has the features of stable controlling performance and rapid, response, and the latter maintenance is also easier. The debugging of the peripheral hardware cir- cuit design is realized in the article.
