Production line efficiency automatic monitoring and analysis system and method

Abstract

The invention discloses a production line efficiency automatic monitoring and analysis system and method, and the system comprises a production line data collection module, an OEE calculation module, and a result display and output module. The OEE calculation module further comprises a theoretical time utilization rate calculation unit, a production scheduling utilization rate calculation unit, a time utilization rate calculation unit, a configuration utilization rate calculation unit, a program point efficiency calculation unit, a performance utilization rate calculation unit, a product qualification rate calculation unit and a data summarization and OEE calculation unit. According to the invention, OEE automatic monitoring of an industrial production enterprise is realized in an automatic and systematic manner, so that the human input cost is saved, and the OEE management efficiency is remarkably improved.

Description

technical field [0001] The invention relates to an industrial monitoring and analysis system and a corresponding monitoring and analysis method, in particular to an automatic monitoring and analysis system and method for large-scale production line equipment, belonging to the field of industrial automation. Background technique [0002] In the actual operation process of industrial production enterprises, the project of OEE (Overall Equipment Effectiveness) management within the enterprise plays an important role. Each production equipment has its own theoretical production capacity. To achieve this theoretical production capacity, there must be no interference and quality loss. OEE is an independent measurement tool used to reflect the ratio of actual production capacity to theoretical production capacity. The calculation formula can generally be expressed as: OEE = time utilization rate * equipment operating efficiency * product qualification rate. Among them, time utiliz...

Problems solved by technology

There are too many manual intervention links in the whole process, and it is very easy to have problems such as wrong or untimely data results

[0005] Secondly, when managers view the report, they need to compare and analyze the significant factors and the rate of change compared with the previous ones; in the process of viewing the data, they cannot intuitively obtain the rate of change and significance

If you need specific research and investigation, you need to open more than a dozen EXCEL sheets to view and analyze one by one, which is time-consuming, labor-intensive, and inefficient

[0006] In addition, since the purpose of OEE management is to monitor and manage all losses in the manufacturing process of the enterprise, it can be known from the calculation formulas mentioned above that most of the OEE algorithms in the industry only cover the three aspects of production scheduling loss, start-up loss and quality loss. Each aspect, and the calculation of each aspect only stays on the surface without further subdivision, which leads to inaccurate final OEE calculation results
