server (21) and a plurality of web servers (22). The 
database layer (3) comprises a communication database (31) and a plurality of application databases (32). The communication 
server (21) is configured to manage communication between the application layer (1) and the service layer (2). The communication database (31) is configured to store communication information between the application layer (1) and the service layer (2). The web servers (22) are configured to respond to the service request of the application layer (1). The application databases (32) are configured to store and manage the 
data resources input from the application layer (1). 
User information and maintenance information in the 
data resources input from the application layer (1) are sent to a manufacturer 
client (100), such that the manufacturer 
client (100) properly distributes maintenance points according to the 
user information, and determines products having high 
repair rate according to the maintenance information, so as to determine a research and development direction.
