【摘要】：隨著生活水平的不斷提高，人們也越來越注重自己的身體健康，醫(yī)療監(jiān)護已不再局限于對重病患者的監(jiān)護，而是走進人們的家庭，使人們即便足不出戶就能得到醫(yī)院醫(yī)生的監(jiān)護和治療。目前越來越多的研究機構(gòu)開始開發(fā)遠程醫(yī)療系統(tǒng)，同時也取得了很好的成效，為遠程醫(yī)療監(jiān)護系統(tǒng)的發(fā)展提供了良好的契機。本文利用無線傳感器網(wǎng)絡將采集的人體生理信號傳送到智能手機或PDA，再由3G移動通訊網(wǎng)絡將信號發(fā)送給遠程監(jiān)護中心。使人們在家也能及時了解自己的身體狀況。 首先對幾種短距離無線通訊技術(shù)進行比較后，選用Zigbee無線通訊技術(shù)完成對人體生理信號的采集和傳輸。對Zigbee的網(wǎng)絡結(jié)構(gòu)和協(xié)議棧進行分析后，組建Zigbee協(xié)調(diào)器節(jié)點星形網(wǎng)絡，包括一個協(xié)調(diào)器節(jié)點和若干個終端節(jié)點。然后對系統(tǒng)的硬件進行設計，，包括芯片的選型和外圍電路的設計。終端節(jié)點的通訊模塊采用CC2530芯片來負責數(shù)據(jù)的傳輸，CC2530內(nèi)置的工業(yè)8051微控制器可以對采集的數(shù)據(jù)進行處理和存儲。PDA采用MSP430F149作為微處理器，對采集的生理信號進行分析處理并通過液晶顯示屏實時的顯示出來。最后通過WCDMA模塊將采集的信息發(fā)送到遠程監(jiān)護中心，監(jiān)控中心對人體的生理信號做出正確的分析后將醫(yī)囑通過短信發(fā)送到用戶的手機。 另外，系統(tǒng)采用改進的Zigbee無線傳感器網(wǎng)絡節(jié)點定位算法進行人員定位，仿真結(jié)果表明該算法提高了定位的準確性，節(jié)約了硬件的成本，從而使監(jiān)護系統(tǒng)在病人遇到突發(fā)狀況時能夠準確、快速的確定病人的具體位置。
[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.
