Abstract

The application relates to a production metering topology modeling method, a system and a storage medium based on metering point variable constraint, which realize the structural construction and the automatic calculation of a production metering model by establishing clear metering point variable constraint and inheritance relation thereof and combining bottom-up data linkage calculation and an embedded reasonable interval verification mechanism. The scheme can ensure that the attributes of the metering data such as dimension, period, unit and the like are kept consistent in the whole network, eliminates the error-prone property of traditional manual statistics, and improves the accuracy and traceability of metering results. In addition, potential data anomalies in the metering process can be timely found and fed back by introducing asymmetric data linkage calculation and real-time early warning, so that the automation level, transparency and management efficiency of enterprise production metering are effectively improved, and the requirements of lean production and cost fine management are strongly supported.

Background In the process industry, such as the fields of chemical industry, metallurgy, pharmacy, food processing and the like, a production process is generally accompanied by a series of complex material processing and energy conversion, and in order to achieve fine management, cost control and efficiency improvement, enterprises need to utilize various metering instruments and control systems to accurately and real-timely meter the material consumption, intermediate products, final products and energy consumption in the production process. The intelligent instrument, the distributed control system, the weighing system and various intelligent equipment are widely applied, so that the real-time data points of the bottom layer which can be perceived by enterprises are increased sharply, the granularity of the data is finer, and a data foundation is provided for the digitization and transparentization management of the production process. However, despite the greatly improved data awareness of the underlying layers, the prior art still has significant pain points in how to effectively organize and utilize such data to form a complete, accurate, traceable production metering system.

This approach is not only inefficient, very error prone, but also the computational logic is separated from the data source, resulting in an opaque overall metering process that is difficult to trace back and verify.
