Description

Technical Field

[0001] The invention relates to an elderly management system, in particular to a face recognition elderly management system based on an industrial computer. Background Art

[0002] In the context of the big data industry, facial recognition will be used more and more in scenarios such as welcoming guests (passenger flow statistics, large data screens, behavioral routes), security (identification alarms, fence alarms), patrols (patrol surveys, patrol reports, patrol statistics), attendance (work attendance, attendance statistics), and access control (employee authority identification, stranger visitors).

[0003] However, there are very few applications of face recognition in the smart elderly care industry. Most of the face recognition that can be used currently requires the user site to provide external IP network information for connecting to cloud platforms or information services. This also brings many problems. For example, these face recognition cameras will inevitably be exposed to the external network, which poses an unsafe privacy factor. In addition, the site needs to cover a fixed external network IP, which increases expenditure costs. There are also cameras on the market that do not have external network access, which cannot be included in the selection, resulting in a narrow selection range and limited use. Invention content
