In the process of manufacturing informatization, workshop level informatization is a weak link. Developing product manufacturing data chain technology is an effective way to improve the level of workshop informatization, which can meet key requirements such as WIP flow, quality control, equipment access, problem traceability analysis, and real-time data collection in the production workshop. It can control production progress and monitor abnormalities in real time, achieve integrated workshop production management, create a digital factory for enterprises, achieve intelligent manufacturing, and provide full link data support.
