摘要: UWB精确人员定位系统在煤矿已逐步推广使用，但目前却缺少与之配套的手持移动式读卡器，用以在发生矿难时对人员进行搜救及日常对定位卡的检测。设计了一种基于UWB技术和SDSTWR双边双程测距算法的矿用移动式读卡器；读卡器以ARM主控器STM32F429和UWB无线收发芯片DW1000为核心，实现了对定位卡的信息读取及精确定位。测试结果表明：移动式读卡器有效无线测距距离400 m，最大静态定位误差不大于0.3 m，最大并发识别量80张定位卡，满足煤矿的使用要求，对灾后开展科学救援及日常的系统维护具有重要的现实意义。Abstract: Ultra wide band （ＵＷＢ） accurate positioning system for underground personnel has been gradually popularized and used in coal mines. However, there is a lack of portable card reader, which can be used to search and rescue personnel in case of mining accidents and test positioning cards in daily life. Therefore, this paper studies and designs a mine portable card reader based on UWB technology and SDSTWR（ｓｙｍｍｅｔｒｉｃａｌ ｄｏｕｂｌｅ－ｓｉｄｅｄ ｔｗｏ ｗａｙ ｒａｎｇｉｎｇ） ranging algorithm. The card reader takes ARM master controller STM32F429 and UWB wireless transceiver chip DW1000 as the core, and realizes the information reading and accurate positioning of the positioning card. The test results show that the mobile card reader has an effective wireless ranging distance of 400 meters, the maximum static positioning error is no more than 0.3 meters, and the maximum concurrent identification number is 80 positioning cards, which can meet the requirements of coal mine and have important practical significance for carrying out scientific rescue after the disaster and daily system maintenance work.
