Design And Implementation Of Smart Temperature Measurement System Based On Bluetooth 4.0 LE

With the development of Internet of things, the development of smart medical and smart health are receiving more and more attention. In order to provide a better service for people, a lot of medical and health monitors and mesurment equipments achieve the function of networking and intelligence.The smart temperature measurement system is developed towarding intelligence and network based on the traditional thermometer.Several technologies are used in this system, such as wearable technology, temperature sensor technology, low power wireless transmission technology and health data management technology. In order to solve chirldren’s termperature mesurement issues, many functions are achived in this system, such as 24 hours real-time temperature measurement, intelligent alarm, remote data sharing, data analysis, etc. On the design perspective, the multifunction is achived in one product based on the design of belt and separation and this improves the user experience. On the hardware perspective, the bluetooth controller is completed based on CC2540 of TI Ltd; The temperature capture module is achived based on high level NTC sensor; The smart thermometer is implemented based on these modules. On the software perspective, the high precision temperature measurement thermometer service and keyfob service are implemented based on OSAL system which is designed based on the Bluetooth 4.0 LE stack; the tempereture data display and analysis system is developed based on iOS system; the server system was established based on ECS, which has data storage, analysis, distribution functions. The system introduced in this paper has been implemented and it could be a reference for the smart health and medical research in the future.
