【摘要】：随着生活水平的不断提高，人们也越来越注重自己的身体健康，医疗监护已不再局限于对重病患者的监护，而是走进人们的家庭，使人们即便足不出户就能得到医院医生的监护和治疗。目前越来越多的研究机构开始开发远程医疗系统，同时也取得了很好的成效，为远程医疗监护系统的发展提供了良好的契机。本文利用无线传感器网络将采集的人体生理信号传送到智能手机或PDA，再由3G移动通讯网络将信号发送给远程监护中心。使人们在家也能及时了解自己的身体状况。 首先对几种短距离无线通讯技术进行比较后，选用Zigbee无线通讯技术完成对人体生理信号的采集和传输。对Zigbee的网络结构和协议栈进行分析后，组建Zigbee协调器节点星形网络，包括一个协调器节点和若干个终端节点。然后对系统的硬件进行设计，，包括芯片的选型和外围电路的设计。终端节点的通讯模块采用CC2530芯片来负责数据的传输，CC2530内置的工业8051微控制器可以对采集的数据进行处理和存储。PDA采用MSP430F149作为微处理器，对采集的生理信号进行分析处理并通过液晶显示屏实时的显示出来。最后通过WCDMA模块将采集的信息发送到远程监护中心，监控中心对人体的生理信号做出正确的分析后将医嘱通过短信发送到用户的手机。 另外，系统采用改进的Zigbee无线传感器网络节点定位算法进行人员定位，仿真结果表明该算法提高了定位的准确性，节约了硬件的成本，从而使监护系统在病人遇到突发状况时能够准确、快速的确定病人的具体位置。
[Abstract]:With the continuous improvement of living standards, people pay more and more attention to their own health. Medical care is no longer confined to the care of seriously ill patients, but into people's families. So that people can get the supervision and treatment of hospital doctors even if they stay at home. At present, more and more research institutions begin to develop telemedicine system, and at the same time, they have achieved good results, which provides a good opportunity for the development of telemedicine monitoring system. In this paper, we use wireless sensor network to transmit human physiological signals to smart phones or PDAs, and then send the signals to remote monitoring center by 3G mobile communication network. So that people at home can also be informed of their physical condition. After comparing several short range wireless communication technologies, Zigbee wireless communication technology is used to collect and transmit human physiological signals. After analyzing the network structure and protocol stack of Zigbee, the star network of Zigbee coordinator node is constructed, including one coordinator node and several terminal nodes. Then the hardware of the system is designed, including chip selection and peripheral circuit design. The communication module of terminal node uses CC2530 chip to transmit data. The industrial 8051 microcontroller built in CC2530 can process and store the collected data. MSP430F149 is used as microprocessor. The physiological signals collected are analyzed and processed and displayed in real time through liquid crystal display (LCD). Finally, the collected information is sent to the remote monitoring center through the WCDMA module. The monitoring center makes a correct analysis of the physiological signals of the human body and sends the doctor's orders to the user's mobile phone by SMS. In addition, the system adopts the improved Zigbee wireless sensor network node location algorithm to locate the personnel. The simulation results show that the algorithm improves the accuracy of location and saves the cost of hardware. So that the monitoring system can accurately and quickly determine the specific location of patients when they encounter emergencies.
