Provided in the present invention is a cloud service center system for flow totalization. The system comprises a flow compensation and totalization sub-system, a cloud data center, and a cloud display control platform. The flow compensation and totalization sub-system performs, by means of accessing real-time data in a real-time database, compensation and totalization on flow data from different acquisition apparatuses, and writes a generated result into a corresponding field in the real-time database. The cloud data center mainly comprises the real-time database and an archiving server. The cloud display control platform performs real-time operation monitoring and balanced scheduling coordination related to the flow data, and conducts comprehensive management on the basis of a large amount of flow data. Compared with the prior art, the cloud service center system for flow totalization connects each field data acquisition node to a network on the basis of a distributed framework on a manufacturing site, and performs centralized management and control on the cloud, thus achieving advantageous effects of the monitoring technology, and providing convenience for system management.
