1. Project Introduction
First of all, the paper clearly discusses the systematic research content at the beginning. Secondly, analyze the system requirements analysis and figure out "what to do". The analysis includes business analysis, business process analysis and use case analysis to further clarify the system requirements. Then, based on understanding the requirements of the system, it is necessary to further design the system, mainly including software architecture model, overall functional module, and database design. The software architecture of this project chooses the B/S mode, and the overall functional modules use top-down hierarchical thinking. Then there is the implementation of the system and coding to implement the functions. The last chapter of the paper summarizes my experience and summary of completing this paper and developing this project. Through the smart elderly care platform, the work efficiency of all aspects of smart elderly care will be substantially improved.
2. System design
2.1 Software function module design
The overall functions of the website are as follows:
2.2 Concept model design
The conceptual model is a description of the things that cause problems in reality. The ER diagram is a diagram composed of entities and their relationships. The E-R diagram can clearly describe the mutual relationships between entities involved in the system.

3.1 Front page
Smart elderly care platform, you can view the homepage, activity information, convenience stores, labor, service items, personal center, backend management and other content on the system homepage, and perform detailed operations;
Activity information. On the activity information page, you can view the activity title, activity category, start time, end time, activity location and other contents for collection and other operations.
Convenience stores. On the convenience store page, you can view the product name, production location, quantity, unit price, product classification, etc. for details or collection operations.
Service items. On the service item page, you can view the project name, project type, project price, labor name, etc. for details or collection.

3.2Backend management
Before entering the system, the administrator and the elderly fill in the user name and password as required on the login page, select roles and other information, and click Login to perform the login operation.
After the administrator logs in to the system, he can manage the homepage, personal center, elderly management, relative management, daily health management, past medical history management, activity classification management, activity information management, commodity type management, convenience store management, commodity purchase management, and labor management. , service type management, service project management, service purchase management, emergency help management, gift distribution management, points increase management, system management and other functions for corresponding operation management
