DCS upper computer data report generation method and system Technical Field The invention relates to the technical field of data processing, in particular to a method and a system for generating a DCS (distributed control system) upper computer data report. Background The distributed control system is widely applied to the continuous and automatic industrial production fields of chemical industry, electric power, metallurgy, pharmacy and the like, and is used for realizing real-time monitoring, data acquisition and process control of the production process. The DCS system is generally composed of a field control layer and an upper computer monitoring layer, wherein the upper computer is responsible for centralized display, storage and management of field device operation data, process parameters and alarm information. Along with the continuous expansion of industrial production scale and continuous improvement of automation level, a large amount of real-time data, historical trend data and alarm and operation event data can be generated by the DCS upper computer in the running process.
