Design and implementation of a wearable system for information monitoring

In view of the limited measurement accuracy and short data transmission distance of existing smart wearable devices, this paper designs a wearable multi-information monitoring system. It achieves multi-directional observation of human body via energy consumption, vital signs and location-tracking information. The overall system consists of three parts: data terminal, LoRa communication network and remote monitoring center. Considering the constraint of power and memory cost, the system adopts a set of appropriate chips for hardware design. As the core of the system, data terminal contains a main control module, a signal acquisition module, and a display and transmission module. The microcontroller controls each sensor to collect different original signals which are performed noise reduction, and then these signals are processed by the algorithm embedded on chips to create the final information for monitoring human body. Test results show that the wearable multi-information monitoring system meets the demand for the measurement accuracy of human body information.
