Gao Yu-qin · Yibiao jishu yu chuanganqi · 2007
The composition of coal mine safety monitoring system interfused with WSN and RFID technology was introduced,and its main functions were described.The hardware principle and software design philosophy of the moving label(RFID) and fixation nodal point(card reader) were suggested,and the comprehensive hardware composition schematic diagram and software design flow diagram were presented.Moreover,low power consumption,frequency band choose,collision prevention principle,signal strength testing,location algorithm and communication protocol of the system were analyzed.
