基于CAN总线冗余结构的矿下智能语音系统设计
Design of Intelligent Voice System Based on CAN Bus Redundant Structure Under the Mine
摘要
Abstract
In order to meet the reliable requirements of intelligent voice communication system in the harsh environment under the mine,it is advertised to integrate the idea of redundant structure into CAN bus intelligent voice communication sys-tem.The system is based on the parallel double CAN bus,and all nodes have communicated with double CAN bus simultane-ously.In the system,with the STM32 microprocessor and AMBE-2000 chip as the core,the voice signal encoded by the AMBE is transmitted to all nodes of the system by the CAN bus.In the meantime,the underpit collected data by the sensor are also transmitted to the ground master station via the CAN bus,so as to realize the real-time voice communication between the ground master station and the underground substations,including the communication among all substations.Besides,the voice signal can monitor and give early warnings of underground conditions.The experimental results show that in emergen-cies,the redundant structure has good anti-interference ability under the mine,which has achieved the expected reliability and real-time performance for the voice communications and data acquisition under the mine.关键词
