The traditional manufacturing production line waste a lot of materials in the process of production, the production line often causes various errors due to human reasons, which lead to results and expectations easily affect. With the help of RFID technology and terminal devices, a highly organized and integrated control system can be formed throughout the production process, which can realize the identification and follow -up of raw materials, components, semi -finished products, and final finished products to reduce the cost and error rate of artificial identification, ensure that the assembly line is balanced and coordinated.
Paste the RFID label on the production materials or products, which can automatically record the number of products, specifications, quality, time, and person in charge of the product instead of traditional manual records; production supervisors read the product information at any time through the RFID reader; Personnel can timely grasp the production status and adjust the production arrangements according to the situation; the procurement, production, and warehousing information are consistent and can be monitored in real time; the system will automatically record the entry-in database information before leaving the warehouse, and can track the location of the item in real time.
The application characteristics of RFID in manufacturing
1) Real -time data sharing
Install the RFID inventory machine and equipment on the various processes of the production line, and place the RFID electronic tags that can be read and write repeatedly on the product or pallet. In this way, when the product passes through these nodes, the RFID read -write device can read the information in the product or pallet label, and feeds the information in real time to the management system in the background.
2) Standardized production control
The RFID system can provide continuously updated real -time data streams, complement the manufacturing execution system. The information provided by the RFID can be used to ensure the correct use of machinery, equipment, tools, and components, so as to realize paperless information transmission and reduce the time to stop work. Furthermore, when raw materials, components, and equipment pass through the production line, real -time control, modification, and even reorganization of production can be performed to ensure the reliability and high quality of production.
3) Quality tracking and traceability
On the production line of the RFID system, the quality of the product is detected by some test positions distributed in several places. At the end of the production or before the product acceptance, all the previous data collected by the workpiece must be clear to express its quality. The use of RFID electronic labels can easily do this, because the quality data that obtained throughout the production process have taken down the production line with the product.
System functions that can be realized by RFID
According to the requirements of the overall design of the manufacturing system, the entire RFID application system includes system management, production operation management, production query management, resource management, production monitoring management and data interface. The functions of each main module are as follows:
1) System management.
The system management module can define the production characteristics of a certain type of product and the users of the management information system, the authority to perform functions and the authorization of users to use the functions, complete the data backup operation, and maintain the basic data common to each subsystem, such as process (bit) , workers, workshops and other information, these basic data are the functional basis for online settings and operation scheduling.
2) Production operation management.
This module accepts the master production plan rollingly, automatically generates workshop for intuitive reflection, and provides decision-making basis for managers. The query function can query the operation information of each station, such as the specific time of assembly, material demand information, employee operation results, quality status, etc., and can also trace the production history, so as to find where and how defective products come out.
3) Resource management.
This module mainly manages some equipment required by the production line, provides the user with the current working status of each equipment, and timely understands the actual use of the existing equipment, so as to provide a reference for arranging production or equipment maintenance. According to the load of the production equipment, develop daily, weekly and monthly production plans for production lines to ensure normal production.
4) Production monitoring and management.
This module mainly provides information to general users, enterprise managers, leaders and other personnel who need to know the production progress in time. It mainly includes real-time monitoring of order execution, real-time monitoring of process production, and real-time detection of station production. These real-time monitoring functions provide users with overall or partial production execution information, so that users can adjust production plans in a timely manner according to actual conditions.
5) Data interface.
This module provides data interface functions with workshop electrical control equipment, IVIES, ERP, SCM or other workshop management information systems.
With the help of RFID technology and related RFID intelligent terminal devices, labels, etc., real-time data collection visualization, punctuality, business collaboration and product information traceability in the production process can be realized. The RFID system is seamlessly integrated with the automation system and enterprise information system to build a supply chain-oriented RFID architecture system, so as to realize the sharing of product information in the supply chain, and fully realize cost reduction and efficiency increase.
