Meanwhile, the property management system can receive the service request of the system and receive the service request from the community management system, processes the service, and synchronizes with the parking lot management system according to the data type, the instruction type, the file type and the service request type which are divided into different service requirements. The synchronous data are divided into data types, instruction types, file types and service request types according to different service types, different types adopt different synchronous schemes according to different timeliness requirements and fault tolerance requirements, and unidirectional or bidirectional data synchronization can be performed between the parking lot management system and the property management system as well as between the property management system and the community management system.
