Abstract:With the economic development in society, people do not only pursue higher material life, but they also pay more attention to their physical health and monitor their own health information. This paper introduces the National Physical Fitness Monitoring System, which is used to monitor the users' personal information, health data and basic motion data, and provide a complete one-stop service solution for health management and chronic disease intervention. The system consists of data statistics and analysis subsystem based on.NET MVC, data synchronization service and data aggregation service based on Windows service and system monitoring program based on Zabbix and so on, and the system can also provide access forms:the Web and the mobile terminal access. The data statistics and analysis subsystem is used to count the user data, and it uses the data mining technology to give the statistical analysis result and the scientific fitness guidance scheme. The data synchronization service is used to prepare data to ensure data integrity and consistency of the system. The data aggregation service aggregates data from the ground station database of provincial data center to the central database, and the data can be exchanged between the central database and the data statistics and analysis subsystem. The system monitoring program monitors the server networking, IIS state, the state of the database as well as the possible errors in the running process of the system, and gives the warning information by message or e-mail. The National Physical Fitness Monitoring System, we designed and developed, provides an effective national physical fitness monitoring and scientific fitness guidance scheme to help users improve their physical condition.
