Is it upper-level monitoring? For our auxiliary facilities, we use the FMCS facility management system ； Battery manufacturing relies on MES, which exchanges data with ERP, FMCS, LIMS, and other systems.
MES, together with upper-level business systems such as ERP and lower-level production equipment control systems like DCS, constitutes the enterprise’s nervous system. Its functions include transmitting instructions from business plans to the production site, as well as collecting, uploading, and processing information from the production site in a timely manner. MES is not merely a system designed for the production site; rather, it serves as a system for transferring information between the upper and lower levels of the organization. 1. MES operation categories (1) Operation monitoring. Metrics are monitored based on operational instructions and boundary management; deviations are reported in accordance with monitoring objectives and set boundary conditions. An interface is provided for operators to enter the reasons for deviations, and various algorithms are used to assess the impact of these metrics. Thousands of monitoring objectives can be defined, each with its own independent boundary conditions. When the device stops operating, it is possible to set records of the deviations that occur. (2) Operation instructions. In conjunction with operation monitoring, it is possible to modify the upper and lower limits of the monitored targets. Monthly plans can be broken down into daily instructions. There is also a complete set of processes including creation, review, and activation. Instructions can contain various pieces of information such as boundary management and corresponding records. These instructions are related to devices and apparatuses; different instructions are issued for different devices. (3) Operation logs. An interface is provided for operators to enter information that occurs during their shift, thereby digitizing shift handover records. A process involving creation, submission, and confirmation within a day is implemented to control access permissions. Based on actual job roles, the permission settings are designed such that information from the operation monitoring and command modules can be automatically generated in the operation logs via a unified data platform. Additionally, a task sub-module is provided as a tool for assigning routine tasks and providing feedback on their completion. The three modules can each perform their respective functions; together, they form an integrated whole that works synergistically to achieve maximum efficiency. Additionally, the operation and management module can also work in conjunction with modules such as the real-time data platform and performance management system, thereby constituting the core of the plant’s informatization construction. 2. Application functions
Data collection: Collects and analyzes real-time data from the process site through intelligent network transmission. Process management: Monitoring the manufacturing process allows for the timely detection of any abnormalities during production, enabling appropriate actions to be taken. Performance analysis: It provides the results of measurements taken during the actual production process, past records, the goals set by the company, as well as customer requirements, in order to analyze performance outcomes.
