摘要现在在21实际，能源是我们最需求的东西之一，当然现在有许许多多的新能源被开发出来，但是真正大面积投入使用的毕竟特别少的。如今，我们最需要的资源仍然使我们日以需求的煤炭。在我国，煤炭方面的安全还是比较健全的，但是再健全我们仍然不能忽视这个问题，井下毕竟是很危险的，对于井下的一切如果可以监控，那对于安全系数将是一个质的提高。
本篇论文先是讲了一下短程的无线通讯技术，例如蓝牙，WIFI等，然后比较这些之后我们采用的ZigBee相比这些有着低能量低利率还能自己组网等的优点，尤其是用在煤矿井下无线方面提别突出。本文介绍了本技术的几个算法，并用了其中的RSSI算法，并改进了它。在硬件方面，我们选取了以CC2530芯片为核心的硬件电路为设计中心。77234

The Underground Wireless Positioning System Based On ZigBee Technology Design
Abstract Now in the 21st century, the energy is one of the things we most need, of course there are lots and lots of new energy has been developed, but really put into use in large area, after all, especially less。 Now, we need to demand of coal resources still make our day。 In our country, the coal security is sound, but we still can't ignore the problem, to improve the mine, after all, it is dangerous for all underground if can monitor, that for the factor of safety will be a qualitative improvement。
This paper first has a speak of short-range wireless communication technology, such as bluetooth, WIFI, etc。, and then compare these after we adopt ZigBee than those with low energy low interest rates can also own network advantages, such as especially used in the coal mine wireless don't highlight。 This paper introduces the technology of several algorithms, and the RSSI algorithm, and improved it。 In the aspect of hardware, we selected the CC2530 chip as the core of hardware circuit design center。
