分析了当前煤矿输送带语音通信系统的现状,提出了一种基于ARM9内核的S3C2440微控制器和CAN总线的矿井输送带语音系统的设计方案。该系统利用高性能ARM处理器S3C2440作为语音识别控制模块,将由语音模块采集来的音频信号经CAN控制器叠加到传输监控信息的CAN总线上,实现了井下输送带监控系统的语音和监控信息混合传输的功能。
The status quo of voice communication system in coal conveyor belt is analyzed and a design scheme of mine conveyor belt voice system based on ARM9 core S3C2440 microcontroller and CAN bus is proposed. The system uses high-performance S3C2440 ARM processor as a speech recognition control module, the voice module will be collected by the audio signal superimposed on the CAN controller monitoring information transmitted on the CAN bus to achieve a downhole conveyor belt monitoring system voice and monitoring information mixed Transfer function.
