在基于 Zigbee 技术的井下人员定位系统中,其设计模型是由人员佩戴微功率标识卡与有固定坐标的读卡器进行无线通信,从而实现模糊或是精确的定位功能。由于标识卡的体积不宜过大,成本不宜过高,同时要保证一定的使用年限,所以标识卡配备钮扣电池供电最为适宜。文中提出了一种基于 Zigbee 技术的井下人员定位系统低功耗标识卡设计,并详细介绍了该标识卡的结构、通信机制及工作原理。
In underground personnel positioning system based on Zigbee technology, the design model is to wirelessly communicate by personnel wearing micro-power identification card and fixed-position card reader to achieve ambiguous or accurate positioning function. As the size of the identification card should not be too large, the cost should not be too high, while ensuring a certain useful life, so the identification card equipped with a button battery-powered most appropriate. This paper presents a low-power identification card design based on Zigbee technology for downhole personnel positioning system, and introduces the structure, communication mechanism and working principle of the identification card in detail.
