摘要
基于PIC单片机的智能语音网关由PIC16F883单片机、MT8880双音频编码解码芯片、键盘电路、显示电路和语音合成电路等组成,具有标准的振铃检测和模拟摘机、DTMF信号编码解码等功能。通过此网关能够将带式输送机沿线或工作面沿线的语音对讲系统直接接入到矿井语音调度系统中,实现调度对输送机沿线或工作面的直接对讲或扩播,也可以通过网关对其进行远程监控。
The intelligents voice gateway based on PIC MCU, by pic16f883 microcontroller, MT8880 DTMF coding decoding chip, keyboard circuit, display circuit, a speech synthesis circuit, etc., with the standard ring detection and simulated off hook, DTMF signal encoding and decoding function. Through the gateway to will bring along the conveyor or surface along the voice intercom system direct access to mine voice scheduling system. The scheduling of conveyor line or working face directly intercom or expansion sowing, can also through the gateway of the remote monitoring.
