针对煤矿井下施救的及时性与高效性,设计出矿井下人员定位系统。以往基于RFID技术的井下人员定位系统受限于安装成本高和通信短距性,不能对井下无线信号区域进行全面覆盖,不能够很好实现煤矿井下人员的全方位精确定位。伴随无线通讯与无线传感网络技术的飞速发展,应用WSN(无线传感网络)技术对人员定位系统进行重新的设计,极大提升了煤矿数字化安全管理的水平。
In response to the timely and efficient rescue of underground coal mines, a staff positioning system was designed. In the past, the downhole personnel positioning system based on RFID technology was limited by high installation cost and short communication distance, and could not comprehensively cover the wireless signal area in the mine and could not well realize the all-round precise positioning of underground miners. With the rapid development of wireless communication and wireless sensor network technology, WSN (Wireless Sensor Network) technology is used to redesign the personnel location system, which has greatly raised the level of digital safety management in coal mines.
