With the development of the economy, traditional intensive processing and manufacturing industries such as home appliances, clothing, electronics, etc. have increasingly high single product manufacturing costs and lower processing profits. In order to improve the overall profit margin of enterprises and optimize management processes, improving production efficiency through information technology transformation has become one of the effective means. In traditional manufacturing enterprises, management mainly focuses on product management, quality management, warehouse management, mobile asset management, on-site personnel management, fleet management, etc. Usually, the collection of production line information is done through manual collection and input. The accuracy of manual collection and input methods is insufficient, and there is a certain error rate. Manual input can only be done on a scheduled basis, resulting in production plans being submitted on a weekly or monthly basis, which cannot be precise to the day. The production data in the system cannot be updated in real time, and the lag situation is severe, which is not conducive to the smooth progress of the production flow and restricts the further improvement of production capacity. At the same time, most of the functional departments in manufacturing enterprises use paper and pen, which makes them face a large number of data errors and reduces productivity.

based onRFIDThe production line management system of technology has become one of the effective solutions to solve the above problems, by adoptingRFIDTechnology and systems can automatically collect production data and equipment status data, providing real-time data for all aspects of the enterprise's business process for production managers. It allows for online monitoring and analysis of production information such as process parameters and equipment operating parameters for important production processes, based on the process characteristics of each process equipment and related process and quality indicators. This helps enterprises achieve automation and information integration of semi-finished and finished product processes, warehouse inbound and outbound management, automatic real-time tracking of the supply chain, sales and after-sales service feedback, enabling them to grasp process information in real time and supervise enterprise business. And achieve real-time tracking of the product lifecycle, improving the efficiency and service level of enterprise production management.

2、 System objectives

Addressing the following common issues in traditional manufacturing enterprise management:

uThe overall production efficiency is low, and on-site management is at a loss;

uThe production process has a large amount of data, and there is a serious backlog in the production line, which cannot form automated circulation and automated data collection;

uNeed to manually input a large amount of data, with low accuracy and work efficiency, and reliability cannot be guaranteed;

uPoor controllability, inaccurate grasp of processing progress, and insufficient monitoring ability of production site status;

uSerious quality loss, high repair rate, and inability to trace quality;

uThe production progress of orders and workshop work in progress, completion data, etc. are unclear, making it difficult to accurately calculate costs;

uThe analysis and statistics of business data cannot be accurate and timely, making it difficult to extract valuable information to guide future production plans.

3、 System architecture

The production line management system mainly includes six parts: employee information management system, work in progress information management system, data collection system, production information management system, process inspection system, and workload statistics system.

4、 System functions

RFIDThe functions of the production line management system are as follows:

uEmployee Information Management System

uWork in progress information management system

udata acquisition system

uProduction Information Management System

uProcess Inspection System

uWorkload Statistics System

5、 System features

uProduction data can be accurately and real-time collected

The system collects real-time production data in the production workshop by workers swiping cards at each process during the production process. Various production data are transmitted to the data controller through the workstation data acquisition terminal and fed back to the system in real time, thereby achieving real-time production data collection and analysis.

uData is transmitted wirelessly without the need for construction wiring, saving costs and investments

Wireless transmission not only ensures accurate and real-time data transmission, but also greatly reduces the use of cables, eliminates line restrictions, and saves labor costs in construction and installation, thereby greatly reducing project cost investment.

uProductivity is improved on the existing basis

Real time production data from the production workshop is fed back to the system, and through system monitoring, the reasons that hinder the smooth operation of the production line can be discovered in real time, and production bottlenecks can be identified in a timely manner. The system monitors the production situation of each workshop, group, parking space, and worker in real time through real-time data collection, so as to discover any abnormal states that occur in any production process and promptly solve bottlenecks that hinder production flow. Overall, it ensures the smooth operation of the assembly line and improves productivity.

uReal time monitoring of the working status of production line workers

The system can monitor the status of production line workers in real time, and through observing the different states of employees at workstations, achieve transparent management of the entire factory and improve the efficiency of factory management.

uReal time tracking of order progress to ensure timely delivery

based onRFIDThe production line management system can start from customer orders and track the real-time progress of the entire production process from material allocation to offline production. Real time tracking of the progress of orders on the production line, when the entire order starts to be fed, how many products have been completed in each process, and which process is mainly stagnant, in order to accurately grasp the production progress of each order and achieve timely delivery.

uStrict quality control to reduce repair rate

Quality is the cornerstone of sustainable operation for production enterprises, and it is also the brand guarantee for enterprises to face customers. The goal is to achieve zero return rate for quality problems. based onRFIDThe production line management system can conduct strict quality management, trace responsibility to individuals, record when products with quality problems were made, which process was done, how long it took, and which worker performed this process one by one. This not only increases production but also controls quality, reduces repair rates, and improves productivity.

uIntelligent statistics of production capacity and piece rate wages

Traditional production statistics and calculation of piece rate wages for workers require a lot of labor and time, and the lag and distortion of data can easily lead to adverse consequences. passRFIDThe production line management system can track workers' production capacity and piece rate wages, improving the efficiency and accuracy of production data statistics. It can provide real-time statistics on workers' actual output and real-time salary reports, facilitating salary accounting and improving the efficiency of the company's production and operation.
