Guo Li Liang · Ceshi jishu xuebao · 2011
Aiming at the safety status of domestic coal mine, a person position system in coal mine based on RFID and the embedded technology was researched and established.Main system structure and working principle of underground mine personnel positioning were detailed.The system used wireless data collection,and data transmission went through the cable.Each officer in the mine was equipped with a transmitter that could send their identity personnel numbers using radio signals out.Along the roadway,the status code station set underground by receiving radio signals could gather information and data staff.The data of mine were collected in all stations and were transmitted to the ground host through the cable.The data analysis,processing and storage were processed by the host based on embedded technology.Ground host and underground monitoring stations used CAN field bus to form a perfectly connected system.At the end of the paper,the software's block diagram was offered.
