微机控制语音文字综合报警系统

ON A MICRO-CONTROLLER INTEGRATED SPEECH/WORD ALARMING SYSTEM

本文讨论的是一种单片机控制的通用文字/语音综合报警系统。探讨了系统的结构组成、使单片机数据存储器寻址范围远超出64KE的分段管理技术及人机接口。还讨论了语音芯片与单片机的接口以及发光二极管点阵用于汉字显示的驱动与接口电路。并对系统的软件设计和单片机内部资源的配置也作了详细的说明。

Discussed in this paper is a micro -controller (8032) based integrated speech/word alarming system, which can report up to 255 alarming events in speaking natural voice and displaying Hanzi(Chinese characters). After a detsil description. of the configuration of the system, a segmentated memory management scheme is developed and it will be used to store high capacity voice data. This scheme enables a micro-controller to address its data memory space far beyond the 6,4KB limit and will cost little performance loss. Also studied are the system bus structure and the interfaces between CPU and natural voice circuits and between CPU and LED display array, which is employed to display Hanzi in 16x16 dot array format. A complete system software is developed and the usage of CPU resources is diecnssed too.
