Abstract
AbstractIn order to promote the development of wearable device informatization and solve the problem of frequent lost of the elderly, we attempt to research an anti-lost intelligent tracker based on Narrow Band Internet of Things (NB-IoT) technology. It covers functions such as remote acquisition and data storage of multi-sensor node information from sensors. The system collects environmental information and health information in real time and transmits them remotely to the IoT cloud platform through NB-IoT technology. The real-time position of the elderly can be taken on the map in APP. The experimental results show that the APP can indicate the specific location of the target on the map in real time and the environmental information in the meanwhile. Through monitoring the health information, the health status of individuals in the environment can be timely known to ensure safety. This paper develops an anti-lost intelligent tracker which uses NB-IoT technology to replace WiFi and Bluetooth. We use NB-IoT technology to achieve data aggregation and long-distance transmission to IoT telecom cloud platform. Compared with other devices on the market, the proposed system has the characteristics of low-consumption, power management and endurable continuous positioning.KeywordsWearable deviceIoT cloud platformNB-IoTIntelligent trackerLow power consumption
