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监控基站进行无线通信,从而实现模糊或是精确的定位功能。由于监控基站与标识卡之间通信频繁且方式单一,因此整体使用ZigBee协议栈就显得不合时宜了。提出了一种基于ZigBee技术、使用IEEE Std 802.15.4~(TM)通信规范的无线通信设计,并详细介绍了其结构、通信规范及工作原理。
In underground personnel positioning system based on ZigBee technology, the design model is that the personnel wear the micro-power identification card and monitor the base station to carry on the wireless communication, thus realize the fuzzy or accurate positioning function. As the monitoring base station and the identification of frequent and single communication between the cards, so the overall use of the ZigBee protocol stack is outdated. A wireless communication design based on ZigBee technology and IEEE Std 802.15.4 ~ (TM) communication specification is proposed. Its structure, communication specification and working principle are introduced in detail.
