Abstract:Cardiovascular disease, as the top chronic disease, seriously threatens the life and health of 10.3% of the population in the country. Effective prevention and treatment of it have become a current research hotspot. At present, the lack of real-time collection terminals and analysis and diagnosis platforms for chronic disease information in China makes it impossible for chronic diseases such as cardiovascular disease to be tracked and quickly and effectively treated. To this end, this article uses the Internet of Things technology, combined with the SQL Server database, C# language, and WPF development technology to design a cardiovascular function test and diagnosis platform based on the Internet of Things. The platform realizes the collection of the health information of patients with cardiovascular diseases through the terminal and uploads it to the cloud using Zigbee communication technology. The platform receives the data through Socket technology and gives a diagnosis conclusion, generates a physical examination report, and the system test results verify the cardiovascular function test diagnosis The rationality and effectiveness of the platform, the experimental results have reached the expected goal, can effectively improve the accuracy of the diagnosis results, and provide data support and platform foundation for the early detection and treatment of cardiovascular and other chronic diseases.
