ZigBee-Enabled Workshop Production Progress and Process Monitoring Management for MES Systems

I. Solution Overview

With intensifying competition in the manufacturing industry and constantly changing market demands, workshop production progress and process monitoring have become crucial for manufacturing enterprises to enhance production efficiency, reduce costs, and enable timely decision-making. In this context, the Workshop Production Progress and Process Monitoring module of the Manufacturing Execution System (MES) has emerged. By deploying ZigBee dual-frequency tags on materials, equipment, and personnel within the workshop, and utilizing ZigBee dual-frequency locators and card reader base stations to collect data integrated with the MES system, it achieves precise monitoring of production progress and processes.

II. Specific Implementation

1. Tag Deployment
   • Material Tags: Attach unique ZigBee dual-frequency tags to each raw material and semi-finished product. The tag ID is bound in the software to information such as stored material numbers and batch details.
   • Equipment Tags: Install ZigBee dual-frequency tags on production equipment. The tag ID is bound in the software to equipment numbers, maintenance information, etc.
   • Personnel Tags: Employees wear ZigBee dual-frequency badges. The tag ID is bound in the software to individual identity information.
2. Dual-frequency Reader Installation
   • Install ZigBee dual-frequency locators and card readers at key locations such as workshop entrances, process handover points, and warehouse entrances/exits.
   • For example, readers at process handover points can automatically identify the arrival and departure of materials, triggering process transition records.
3. MES System Integration
   • Data Transmission: Transmit data collected by the ZigBee dual-frequency card readers to the MES system in real-time.
   • Process Monitoring: The MES system determines the start, progress, and end times of processes based on material flow and equipment usage. For instance, when an item with a specific material tag arrives at a work area for a particular process and the corresponding equipment starts operating, the MES system records the process start; when the material leaves the area, the MES system records the process end.
   • Production Progress Calculation: The MES system calculates overall production progress based on process completion status. For example, if a product requires 10 processes and 6 are completed, the production progress is 60%.
4. Exception Handling
   • If materials remain at a process for an excessively long time, the MES system triggers an alarm.
   • In case of equipment failure, the system quickly identifies the operating employee at the time through the association between personnel badges and equipment tags, facilitating traceability and problem resolution.

III. Benefit Analysis

1. Improved Production Efficiency: Precise process monitoring reduces waiting times between processes, enhancing overall production efficiency.
2. Quality Traceability: Facilitates tracing the production status of products at each process, aiding quality control.
3. Real-time Monitoring: Management can gain real-time insights into production progress, enabling timely decision-making and adjustments.

The Workshop Production Progress Monitoring MES system plays a pivotal role in modern manufacturing. Through real-time monitoring, scheduling, and data analysis, it enhances production efficiency, resource utilization, and production quality. By effectively managing and optimizing production processes, enterprises can achieve higher production efficiency, faster delivery cycles, and increased customer satisfaction. Therefore, the Workshop Production Progress Monitoring MES system is a vital tool for manufacturing enterprises to realize smart manufacturing and enhance competitiveness.
