 目前,大多数电梯楼层语音系统都采用专门语音器件,但缺陷多。针对这种情况,设计了一种基于CPLD和VS1011E解码器的电梯语音系统,该系统主要采用STC89C58RD+C、CPLD、VS1011E和Flash技术,控制器按照输入的信息,向CPLD发出控制命令和传送数据,CPLD根据接收到的命令按照逻辑规则读写Flash并对MP3设定内部控制寄存器和传送音频数据,MP3输出的模拟信号直接驱动外接功率放大器,实现了电梯语音服务的智能化和自动化。
Abstract:
 At present, most elevator audio systems, which are designed by using special audio chip, are far from being flawless.The elevator audio system based on MP3 is designed which is based primarily on STC89C58RD+C、CPLD、VS1011E and Flash and so on.According to the information input controller to control CPLD issued orders and transmit data to the receiving CPLD orders in accordance with the rules of logic and literacy Flash MP3 set of internal control registers and data transmission audio, MP3 analog signal can be output directly to an external power amplifier audible.This system succeeds the intelligence and automation of elevator voice service.
