\begin{tabular}{p{113.8 pt} p{113.8 pt} p{113.8 pt}} \hline \hline  & \multicolumn{2}{c}{**Traditional Environment and Green Care**} \\ \cline{2-3}  & **Traditional Therapeutic Environment** & **SGCS Therapeutic Environment Green Care** \\ \cline{2-3}  & **Green Care** & **SGCS Therapeutic Environment Green Care** \\ \hline \multirow{4}{*}{Manpower} & The maintenance, monitoring, and control of environmental conditions must be performed in person to provide effective physical care for the elderly. & The introduction of remote monitoring and real-time warning can reduce manpower and arrange physical rehabilitation for individual seniors. \\ \cline{2-3}  & Environmental protection and energy saving resource-intensive. & Environmental maintenance through rules of thumb is less grounded and more resource-intensive. & Referencing the data returned from IoT sensors to achieve the maintain the environment; maintenance resources can be used efficiently. \\ \hline \multirow{2}{*}{Food security} & The use of pesticides to eliminate pests and diseases cannot be avoided. & The use of drugs is strictly prohibited by providing green nutrients through the ecological cycle. \\ \hline \multirow{2}{*}{Production quality} & The crops produced are susceptible to imbalances in supply and demand, as well as to ecological imbalances. & Ecological advantages of precise farming production and easy-to-control plant growth. \\ \hline \multirow{2}{*}{Maintenance cost} & Maintenance of the environment requires considerable human and resources. & Eco-cyclic IoT fields need to be built initially, and the environment can be monitored with alerts ensuring effective control of people and resources. \\ \hline \multirow{2}{*}{Land pollution} & The use of organic or chemical agents is required for soil conservation and water recycling. & The use of off-ground farming and medium instead of soil can effectively reduce contamination. \\ \hline \multirow{4}{*}{Site restrictions} & A large area is needed for green plant farming, with a limited land area and limited space use. & Effective planning can be implemented for the site; the SGCS can be large or small and can be developed horizontally or vertically to effectively use space. \\ \hline \multirow{2}{*}{Promote social activities} & Only passive waiting for seniors to communicate and discuss the environment. & An app is provided to convey farming information, guide participants to online or offline communication topics, and effectively promote social activities. \\ \hline \multirow{2}{*}{Therapeutic care} & Only passive waiting for the elderly to carry out physical fitness activities. & The system can provide physical rehabilitation for the elderly, as well as effective physical therapy. \\ \hline \multirow{2}{*}{Traceability} & None & Environmental parameters can be stored, and data can be tracked. \\ \hline \multirow{2}{*}{Remote monitoring} & None & The server pushes messages to the client side, enabling a remote monitoring environment. On the client side, the human voice can be used to control the environment through the server. \\ \hline \multirow{2}{*}{Real-time alerts} & None & Alert thresholds can be set for changing environmental conditions. \\ \hline \multirow{2}{*}{Human–machine interaction} & None & An alter app is provided to send notifications about maintenance processes and guide users to engage in physical fitness and care activities according to SOP. \\ \hline \hline \end{tabular}

Table 2: Comparison of traditional therapeutic environment green care with the proposed SGCS therapeutic environment green care. The confusion matrix shows that the automatic control model does not suffer from overfitting and can accurately predict the two types of data. The device marked as 0 represents the open state, devices marked as 1 represents the closed state, and the recall value labeled as 0 is as high as 98.11%.
