基于FPGA的智能呼叫系统的设计

Design of intelligent call system based on FPGA

研究了智能呼叫系统,能实现64人呼叫,在有人呼叫时,启动语言对话系统,实现呼叫者和值班管理员对话,显示第一或优先呼叫者编码,并有光声提示,同时还能存储多人呼叫信息。将系统分成若干部分,主要包括呼叫信号编码和译码电路、呼叫存储电路、语音放大电路、控制电路、模拟电子开关电路、模拟选择/分配电路等部分。数字部分功能用Altera公司的FPGA器件EPF10K10TC144-3实现。

This article studies the intelligent call system to realize sixty-four persons＇ call When people call, the language dialogue system will be started to achieve the dialogue between caller and admimstrator. The system is divided into several parts, mainly including parts of the call signal encoding and decoding circuit, call memory circuit, voice amplification circuit, control circuit, analog electronic switching circuit, analog selection/distribution circuit and language integrated circuit. The function of digital part can be achieved by FPGA devices-EPF10K10TC144-3 produced by Altera Corporation.
