Based On Zigbee Technology For Empty Nest Elderly Of Community Healthy Monitoring System Terminal Research

With the development of economy and society,aging has become a global problem in twenty-first Century,while China is the world's aging more serious country,problems seriously restrict the development of social economy and social progress.Based on the Empty Nester practical research,combining the development of the industry,put forward a kind of health monitoring system of Zigbee technology oriented community Empty Nester based on empty nest elderly can realize real-time monitoring of vital signs,abnormal alarm function.This terminal can not only solve the "difficult to see a doctor" in the title,but more importantly,to create a prevention,prevention and control,national health,community health care model,reducing the health risks of the empty nest elderly.The main contents of this paper are as follows:By reading the literature and the use of devices available on the market monitoring equipment related technology,analyzed and summarized.According to the system requirements,the overall design scheme and the selected components are proposed.The center rate and the pulse module of the monitoring module are monitored by the photoelectric method,and the heart rate is calculated by the single chip interruption counting function.The body temperature detection module used the thermistor to detect the body temperature methodand the blood pressure monitoring module through the circuit design and use of improved post-wave method for blood pressure detection and calculation;and through the microcontroller that the external circuit to complete the alarm.This system is an integrated circuit of monitoring terminal which integrates the functions of GPS and location.To monitor the real-time monitoring of the object and the abnormal data to the police,to ensure that the empty nest elderly can get the first time treatment.The hardware platform is a solution of MSP430F149+CC2530 transparent transmission module,the software was developed by IAR Embedded Workbench+ C language platform.The main program and the related display and alarm procedures were wrorte,and the related algorithms are optimized,to achieve the monitoring object real-time monitoring,remote storage data timing and abnormal data alarm function.The monitoring system is tested and analyzed by various methods.The results were compared and analyzed with the terminal monitoring results of the system and it proved that the system monitoring terminal can be more rapid and accurate monitoring of the pulse,heart rate,body temperature,blood pressure,further verify the reliability of the system terminal.The monitoring terminal of this system follows the design principles of low power consumption and portability.Using the GPS integrated module to obtain location information,and life parameter data,location information and the alarm signal was sent to the Zigbee coordinator.The system detected four vital signs,and the reserved ports in the hardware design can be extended to detect other vital signs so as to facilitate the industrialization of the system terminals.
