Application of Intelligent RFID System in Industrial Control

RFID systems are now almost standard in modern processing. Use the RFID system related to the application, and use the corresponding reader and coordinated software. With the help of this system, the production process and the logistics required for this can be precisely formulated and perfectly coordinated with each other.


The RFID system cannot generate a batch of transponders on a component in batches, and can provide data to the automatic control device of the manufacturing process and the spare parts supply process. In this way, the history path of each component can be recorded throughout and traced back. In addition, if the data carrier is permanently mounted on the target, product life cycle management can also be effectively performed. The target can be verified as an original component at any time, and the prescribed quality inspection certificate can also be recorded on the RFID system.

The biggest challenge for production is that no one production process is the same as another production process, so a successful RFID system cannot be manufactured in batches. Any RFID system must be closely matched with the process of the corresponding enterprise. Which solution is preferred depends on the requirements of the specific application. Therefore, the road to a well-functioning RFID system must always go through a comprehensive analysis of all participating processes and framework conditions.

In machine and equipment manufacturing, the effective installation of RFID-enabled business processes also depends on many other factors: such as sophisticated hardware integration, data management, including corresponding back-end systems, and personalized RFID data, which can be provided according to The standard is connected with ERP / EDI data.

Traceability provides safety. Every part identified by RFID is recognized by the reader at an important part of the logistics chain, and is collected by a higher-level data network. Continue processing and write additional when necessary. The data. Using this information, each process step can be effectively implemented and controlled. In addition, decentralized storage of production data can improve the system's safety against failures, and enable components to smoothly enter and exit the processing production line without problems—for example, during subsequent processing.

The special antenna design of the UHF metal tag can use the electromagnetic coupling device between the tag and the base to work, so the metal bottom plate itself becomes an extended antenna, and it helps to reliably transmit data at a long range.

In practice, the staged processing on the processing or assembly line depends on the information of the RFID tag: Only when the components are clearly identified according to the processing drawings and the relevant important production and quality data are approved, the equipment is approved for continued processing. Modern data carriers such as RFID tags or smart tags can keep product life information on the components for a long time, so they can also be traced back in detail after several years.

Typical information on smart tags, such as individual product data and identification codes, so-called "Unique ID"; In addition, there are information about the processing status and quality parameters in production, as well as the processing conditions and time. For after-sales service, the information recorded on the label is also useful. For example, in terms of maintenance intervals, repair services, or warranty; at the same time, modern encryption technology can prevent any illegal calls to confidential data.

Take the maintenance of machines and equipment as an example: staff in this area can call all data of components without contact. In this way, the required spare parts can be purchased in strict accordance with the series model, and the maintenance and repair work done are recorded on the data carrier. In addition, once a certain component often fails, the manufacturer can smoothly and efficiently conduct the necessary telephone return visits, which can effectively avoid greater subsequent damage and subsequent costs.

Important data is located on the target. Now, intelligent RFID systems are increasingly occupying new fields of use, such as metal bases, which can generate electromagnetic fields when reading and writing transponders through radio networks. If such a tag is on a solid metal base, transmission failure and range limitation will occur prematurely. For this, Schreiner
Logidata ’s UHF metal tag can be used in this metal environment: its special antenna design can even use the electromagnetic coupling device between the tag and the base to work, so the metal itself becomes an extended antenna, and it helps Reliable data transmission at range.

Reliable identification under harsh conditions In machinery and equipment manufacturing, innovative technologies open up entirely new possibilities, such as uninterrupted tracking during the production process. If a single component or a complete set of equipment must pass through a paint production line (paint booth), it turns out that many links are required. Because the traditional identification system cannot withstand thermal and chemical loads on the paint production line, the production data has been transferred from one data carrier to another system in the past when the transition from rough parts to paint. For this purpose, for example, the use of an auxiliary cover plate with an identification code, or the use of an expensive active RFID system housed in a fully sealed and insulated enclosure. Most of these two solutions are not fixed on the product itself, but fixed on the special paint production line slide. This is a hidden danger of quality problems, its price is very expensive, and it takes time and effort, and it is also one of the biggest sources of failure in the tracking process.

With the innovative UHF metal tag, these shortcomings are solved: the RFID tag is fixed on the product all the way, which is more advantageous in manufacturing and operation than all previous systems. This is a great progress in vigorous research and development work. High-tech response tags must not only function properly on the metal base, especially the structure must be flat, but also must withstand high temperatures of 220 ℃, also in the painting process It must be safe.

Based on RFID automatic identification, it also has great potential for controlling the usability of materials. In order to obtain a sufficient number of components in the right place at any time during the processing process, many companies in the technology industry use the Kanban system to work. The principle of the system is very simple and very effective: once a processing site requires less than the minimum number of components, the relevant staff will post a printed kanban card on the reader to start the supplementary supply system .

Using RFID technology can further simplify and automate these processes. If each component is labeled with a transponder, the consumption status and current inventory on the processing station can be automatically reported to the EDV system via radio and real-time. Therefore, even the production sites or parts supply enterprises that are far away can be precisely coordinated to make the mutual deployment perfect.
