Abstract
Aiming at the disadvantages of traditional coal mine voice communication system such as short transmission distance, weak anti-jamming capability and poor voice quality, designed a voice communication and data collection system based on double CAN bus. The system adopts double CAN bus transmission design, CAN 1 bus is responsible for transmitting voice data, CAN 2 bus is responsible for real-time data acquisition. Double CAN bus design make voice information and control information does not interfere with each other, ensured the timely and accurate information transmission. Introduced hardware and software design of the system in detail, experimental tests showed that the system is stable with long transmission distance and high voice quality, and has certain application value.
