Design And Implementation Of Pulse System Based On Multi Node ZigBee

At present, China constantly deepen reform to protect and improve people’s li velihood, but the basic conditions of our country still exist many difficulties, such as high cost. Under double pressures of the lack of medical resources and the w aste of medical resources of the public, the special online service platform was b orn[1], the rapid growth of the health services industry has been silent for a long time, many health care professionals involved in the Internet and started to pay attention to health care consulting field. In this way, patients can stay at home, a nd easily get professional and efficient advisory services.In the field of health consultation, the most worthy of praise is the human p hysiological parameters consultation. As an important index of human, pulse contai ns abundant human physiological information. The photoelectric which gather hum an pulse information with fast dynamic response, signal detection ability, stability, good reliability and other advantages has been widely used. The elderly and child ren is a special group, their life health is the focus of attention. In this case, the elderly as well as children in this group is measured as the object.As a simple wireless communication technology, ZigBee with its low comple xity, low power consumption, low cost, the advantages of ad hoc networks is gra dually emerging in the short distance wireless communication. In the aspect of inf ormation technology, industry intelligence, ZigBee technology has been widely use d. According to the characteristics of low power consumption, ZigBee technology can be used in any wireless data acquisition system of the body parametersAndroid (Android) system, which is the highest market share of Linux operat ing system with the completely open source, is widely used in intelligent mobile phone and tablet computer. Android service constantly upgrading for the establish ment of the Open Handset Alliance launched by Google (OHA, Open Handset All iance).It can let the machine equipment and the body better interaction with friend ly interface.This paper mainly studies a kind of pulse measurement system of multiple n odes based on the technology of ZigBee, the contents of which are as follows:(1)Depending on the background of design research, it analyzes the research significance and domestic and foreign development of this subject[3].According to the characteristics of pulse signals, it deduces the theoretical basis of the pulse signal, selects the ZigBee technology as the networking scheme, based on which it puts forward the overall scheme of the Android query platform.(2) Then it selects CC2530 chip produced by TI (Texas Instruments) as the ZigBee RF chip, and with this chip as the core, it designs the peripheral circuit based on the functional characteristics of each node. The data is transmitted to PC through the serial communication interface, and is displayed through simple interactive interface.(3) It adopts the LABVTEW display pulse curve and saves the data in the local database. Then by adopting the LAN Android platform or WeChat public consultation platform, it can read the physiological information of testees.(4)Finally, it completes the test of The final completion of the whole pulse system. The system fulfills acquisition parameter of ZigBee wireless network ultimately.As the monitoring, this design uses Android devices such as handheld tablets and mobile phones, which have the advantages of popularization, convenience and speediness.
