Description

Technical Field

[0001] The utility model relates to an alarm device, in particular to an intelligent fall alarm device. Background Art

[0002] The fall alarm systems currently on the market usually rely on wearing additional external devices to detect fall events, which may limit their scope of application and mobility. Secondly, there is a certain false alarm rate, and sometimes non-fall events are mistakenly identified as fall events, which may cause unnecessary panic to users and question the reliability of the system. What's more, some fall alarm systems need to monitor users' daily activities and physiological data, which may cause a certain degree of intrusion into users' privacy, causing users' concerns and privacy leakage risks. The current fall alarm system still has deficiencies in data analysis and personalized customization. The system fails to fully explore users' personalized needs and lacks intelligent analysis and feedback. Some fall alarm systems may lack practicality, comfort and portability, and are too difficult to operate for most elderly groups. The user experience and acceptance need to be further optimized to ensure that the system better meets the actual needs and expectations of users. Utility Model Content
