在智能医院的研究中我们进行了严格的计划和细致的探索，在设计中我采用的Arduino单片机作为协调器对信息进行处理，把具有Zigbee技术收发技术的Xbee芯片作为组建无线网络的节点芯片。在设计硬件的时候，重点对AVR系列的Arduino单片机和外围电路进行分析研究。详细介绍了基于三角形的定位原理。所要设计的系统必须对协调器，参考节点，移动节点进行系统的设计。首先我们需要对Xbee进行配置让它们形成一个网络；其次监测是否有移动节点加入，一旦有新的节点加入立刻发送数据请求用来得到移动节点的数据信息；然后把所有参考节点得到的消息都传输给协调器进行数据处理从而得到移动节点的位置信息。最后通过通信把数据传输到上位机进行显示并根据情况给协调器发送命令。

Abstract
Due to the aging population in our country is more and more serious, everyone's quality of life also in rising, people on the high quality of life, health, improve the health care system and higher. In the wireless communication technology gradually improve today, the use of wireless technology and medical applications more and more. The use of wireless network technology for the hospital to implement accurate real-time positioning and monitoring is one of the important applications. This level of improve the efficiency of the hospital, so that patients get more comfortable service, whole provides the quality of medical staff, but also to the use of medical equipment to the big, is the necessary technology to establish a modern hospital.
In the research of intelligent hospital we were strict planning and careful exploration, I use in the design of the Arduino microcontroller as a coordinator of information processing, with the XBee ZigBee transceiver chip as a form of wireless network node chip. In the design of hardware, the focus of the AVR series Arduino microcontroller and peripheral circuit analysis and research. The positioning principle based on the triangle localization algorithm is introduced in detail.. In the aspect of node software, the workflow of coordinator, reference node and mobile node is analyzed, and the localization algorithm of mobile node is realized, and the positioning of the nodes is effective.. In the localization network, the stability of the system is improved by increasing the number of reference nodes, and the existence of the blind zone is largely reduced, and the real-time of the positioning is ensured.
