  With the fast advancement of smart devices and Internet of Things (IoT)
technologies, certain established situations are opening up new avenues of
exploration. Particularly in the sphere of healthcare, the diverse and big
population, the complicated and professional data, and the stringent
environmental requirements for certain medical scenes and equipment all impose
exceptionally high standards on hospital administration. As a result, an
effective and secure Internet of things system is critical. This article
proposes an IoT system that might be used in hospitals for a variety of
purposes. This system collects data by LoRa, Wi-Fi, and other ways, uploads it
to a cloud platform for processing over a secure connection, and then feeds it
back to users in real-time via the user interface. This system enables precise
indoor localization through the use of UWB, ECG signal detection, environmental
monitoring, and data on people flow.
