Abstract

The invention relates to a distributed data statistical processing system and application thereof. The distributed data statistical processing system comprises a database server, a first OLE for process control (OPC) server, a second OPC server, a WEB server, programmable logic controllers (PLCs) and a monitoring server. The database server is respectively connected with the first OPC server and the WEB server, the first OPC server and the second OPC server are both connected with the PLCs, and the second OPC server is connected with the monitoring server. The application of the distributed data statistical processing system particularly comprises steps that the PLCs automatically store basic statistical data into the database server and transmit the basic statistical data to the monitoring server through the second OPC server; the WEB server stores reported data into the database server in real time; the database server sequentially establishes daily statement, monthly statement and annual statement according to a basic statistical data table and a reported data table at regular intervals. Compared with the prior art, the distributed data statistical processing system and the application of the distributed data statistical processing system have the advantages of balancing data processing masks, improving data statistical processing efficiency and the like.

Description

technical field [0001] The invention relates to a data processing device for an automatic control system, in particular to a distributed data statistical processing system and its application. Background technique [0002] With the technological development of automation control systems, it has become a trend to rely on databases for data statistical processing capabilities, and to perform multi-directional and large-scale data statistics on real-time working condition data. However, real-time working condition data usually has a large processing scale and requires high processing speed. At present, this huge data processing work is undertaken by the database server alone. From the perspective of the system, the task distribution is unbalanced, which increases the computational complexity of the application server and workload, making the database server overwhelmed. [0003] Statistics can generally be divided into two categories: basic statistics and summary statistics. ...
