Real-time data acquisition system for quality of product on production line

Abstract

The invention discloses a real-time data acquisition system for quality of a product on a production line. The system includes a production management layer, a data acquisition layer, and an object recognition layer. A signal end of the production management layer is connected to industrial Ethernet through a wireless network; an output end of the production management layer is connected to the data acquisition layer in an interaction manner; the signal end of the data acquisition layer is connected with the object recognition layer in the interaction manner; a terminal controller is disposedinside the data acquisition layer; the signal end of the terminal controller is connected with a reader / writer and a barcode gun; and an interaction port of the production management layer is connected with a cloud service platform. The system achieves a function of visualization and transparency of a production process, meets real-time and accurate requirements of production field data by lean production, can timely and effectively collect production data required for on-site monitoring, provides data support for an upper-level application and on-site management, and achieves synchronizationof logistics and information flow.

Description

technical field [0001] The invention relates to the field of real-time data collection systems, in particular to a real-time collection system for product quality data on a production line. Background technique [0002] At present, barcode technology is the most mature and widely used identification technology. Barcode technology appeared in the 1940s and began to be used in the industrial field in the 1970s and 1980s. Since its development, barcode technology has been widely used in material identification in assembly manufacturing, and has a very high technical maturity. Its first-time reading success rate is greater than 98%, and the reading error rate is about one in a million. It is a marking technology with low cost, fast information collection speed, high reading accuracy and wide application range. [0003] In the lean production mode, barcode technology, as an economical and practical object identification technology, is introduced into the production site for prod...

AI Technical Summary

Problems solved by technology

[0007] (1) At present, due to the limitation of the barcode itself, it is not enough to meet the automatic identification of mass production elements and the real-time data collection under the lean production mode: the industrial production environment is relatively harsh, and the barcode is easily polluted by oil stains and scratched by sharp and hard objects , High-temperature and high-humidity air erosion and other damages, resulting in the barcode falling off, deforming or staining, resulting in a linear decline in the success rate and accuracy of barcode information reading;

[0008] (2) The reading conditions of the barcode are relatively harsh, requiring short-distance scanning within a short visual range, which often requires manual participation, which not only increases the workload of the assembly workers, but also affects the reliability and real-time performance of information collection. and accuracy;

[0009] (3) The information storage capacity of the barcode label is small, and the production process is cumbersome. A barcode printer needs to be installed, and the data is solidified after the barcode is produced, and cannot be added or modified at will during the production process, so it is impossible to record real-time data generated during the production process
