Embodiment Construction

[0054] like Figure 1-3 As shown, the present invention provides a real-time data synchronization method in a distributed environment, and the method includes the following steps:

[0055] Step 1: Establish a sub-center real-time data center.

[0056] The synchronization method includes several sub-center real-time data centers (referred to as sub-centers) and one real-time data center of the general center (referred to as the main center). The data entered into the sub-center for synchronization includes the data from the automatic database and the manual database. The automatic database is the data collected automatically by the telemetry station, at least one; the manual database is the data entered manually. The sub-center includes the fusion library and the rejected library.

[0057] This step includes the following sub-steps:

[0058] 1.1 The data collected automatically by the acquisition terminal enters the automatic library, number the automatic library (I1, I2...I...

Abstract

The invention discloses a real-time data synchronization method in a distributed environment. The method is characterized in that, to begin with, establishing a branch center real-time data center and a total center real-time data center; collected data being exchanged in real time and entering the data center, and being stored to a fusion database and a loser database of the data center according to configuration; and then synchronizing data from the total center and data from the branch center, during the synchronizing process, the branch center is responsible for initiating synchronization operation and maintaining increment consistency among previous synchronization operation, and the total center is responsible for responding to the synchronization initiated by the branch center and finishing the synchronization process according to the configuration. With the method, the problems of conflict and business operation incapability and the like due to inconsistency of real-time data of each department in the distributed environment are solved, and meanwhile, the method can help to improve accuracy and efficiency of data synchronization.

Description

technical field [0001] The invention relates to the technical field of data synchronization, in particular to a real-time data synchronization method in a distributed environment. Background technique [0002] For the existing data acquisition system, there are many problems in the process of data to the database. For example, in the field of hydrology, the data collected by the telemetry station has low data quality, data stability and security, especially in the application of government departments. The acquisition system is different from industrial acquisition. Government departments and local municipal departments need a lot of data sharing and exchange, and each department has its own acquisition system. For the acquisition of the same sampling point, there are inconsistent data between departments. The main reasons are: the data collected by the telemetry stations of the provincial center and the prefecture-level center are different; the modification operations of t...
