一、概述智能化语言实验室是提高外语教学质量所必需的一种教学设备.国内原有的语言实验室基本上都采用继电器来实现各种功能,操作比较复杂.从国外进口的语言实验室应用微机控制功能的转换,但价格昂贵.本文介绍的智能化语言实验室的主控电路操作简便,各个功能键具有记忆能力,在工作状态转换后,微机能记忆转换前的状态,以便在接受合理控制信号后,返回原工作状态.主控电路采用了Z-80微处理器的专用
First, an overview of intelligent language laboratory is to improve the quality of foreign language teaching is necessary for a teaching device. The original language lab basically use relays to achieve a variety of functions, the operation is more complex.Language laboratories imported from abroad The application of microcomputer control function conversion, but the price is expensive.This article describes the intelligent language laboratory control circuit easy to operate, each function key has a memory capacity, after the conversion of the working state, the computer can remember the state before conversion in order to accept Reasonable control signal, return to the original working state. The main control circuit uses a dedicated Z-80 microprocessor
