Research And Development Of Physiological Parameter Monitoring System Based On ZigBee

With the rapid development of information technology,wireless communication technology and wireless sensor technology,to the medical field,its bring new ideas and solutions to promote the development of intelligent medical.Intelligent medical technology is the uses of advanced Internet of things technology to achieve the interaction between patients and medical personnel,medical in stitutions,medical equipment,to build an information platform.The human physiological parameters monitoring system is an important part of intelligent medical care,through intelligent medical equipment for real-time monitoring of the patients,the human physiological parameters of monitoring data through the wireless network to send to the remote monitoring center,medical staff can keep abreast of patient's physical condition.This brings great convenience to medical staff and patients.In this paper,a physiological parameter monitoring system is developed for the demand situation of intelligent medical system.The system was a combination of ZigBee wireless communication technology and human physiological parameter monitoring technology to realize the acquisition,processing and wireless transmission of physiological parameter information.The system can accommodate hundreds of monitoring nodes rely on strong networking capabilities of ZigBee technology,while the monitoring center software can be real-time display of the monitoring of the physiological parameters of information.The system is mainly composed of three modules: data acquisition module,data processing and transmission module,monitoring center data processing and management module.The data acquisition module of the system realized the collection of human physiological parameters such as body temperature and heart rate data.The DS18B20 was used to design body temperature acquisition module,and the heart rate acquisition module of PPG technology was used to design the system;The data processing and transmission module uses the CC2530 as the core processor to process the data collected by the sensor and then sent to the ZigBee network coordinator.The final data collected by the network coordinator is sent to the personal computer through the serial port,the monitoring software can display physiological parameters such as body temperature and heart rate on personal computer,if body temperature and heart rate over the normal range will be issued an alarm.The physiological parameters monitoring system developed in this paper allows patients to move freely within a certain range.It solved the problem of traditional manual monitoring or cable monitoring bring about by the large amount of human and material resources,limiting the scope of activities of patients,bring tension to patients.It also overcomed the difficuties in the convenience and real-time.It reduced the burden to patients and not affected by cable monitoring.This system was a great help to the rehabilitation of the disease,it uses multi-node monitoring and wireless transmission also improved the efficiency of medical staff.
