Abstract

The invention provides a system and a method for automatically calculating the start-stop running time of a chemical device, wherein a standard reference data storage module is used for solidifying design parameters of the device to provide a standard for running analysis, a data acquisition module is used for forcedly unifying a time stamp format to eliminate format confusion risks in manual recording, a dynamic calculation engine is used for processing complex scenes by adopting a spreadsheet and an algorithm to process the running scenes with missing stop time and cross periods, an analysis comparison module is used for checking the design parameters of the device and actual running data in real time to identify abnormal working conditions that the start-stop frequency and the running time deviate from a design threshold value, and a suggestion output module is used for outputting a specific maintenance strategy based on an analysis conclusion to push an operation and maintenance mode to be changed from post-treatment to pre-warning. The automatic calculation system for the start-stop running time of the chemical device solves the technical problems that the statistical efficiency is low, the calculation error rate is high and a dynamic early warning mechanism is lacked because the automatic calculation system relies on manual data acquisition and input in the prior art.
