To date, various forms of barcodes remain the commonly used technology for object identification. However, RFID (Radio Frequency Identification) technology is increasingly being used in the planning of new process industry projects and the design of final products, often in products requiring multiple identifications. This is particularly true when historical information needs to be recorded, when data exchange with the product being inspected is required, or when conventional barcode labels are not feasible. RFID technology can improve and optimize internal logistics processes because materials can be identified non-contactly over short distances. Typically, the detection distance for RFID is measured in centimeters to meters.
Common applications of RFID (Radio Frequency Identification) technology in daily life include access control and the identification of animal and product consistency. In these applications, RFID technology benefits businesses by reducing the number of staff required, as inspection (of goods entering and leaving the warehouse), sorting, and consistency identification are all automated. Applications of RFID technology in goods tracking, such as at supermarket checkouts and for inventory tracking, are currently in the experimental stage. To achieve these goals economically, active transponders are needed, and the RFID identification range needs to be increased to 2-3 meters.
How is it applied in the industrial sector?
In the industrial sector, the first consideration is to use radio frequency identification (RFID) technology in the labeling of transport vehicles such as containers, bulk bags, and pallets to improve internal inventory and logistics management and reduce potential confusion incidents.
The storage and transportation of powdered, liquid, and gaseous raw materials often utilize reusable, multi-purpose containers, such as drums or bulk containers. To avoid product mixing or cross-contamination, reliable cleanliness must be ensured. New or cleaned drum-like containers should be used for filling, or containers containing the same product should be used for filling and transportation. In this case, the containers should be equipped with controllable transponders that record container filling data (e.g., container production date, product number, batch number, and filling date). Some transponders should also have password-protected access. Using RFID (Radio Frequency Identification) technology makes it possible to determine the substance contained in the container without a central database.
In the chemical industry, liquids, gases, and powders are often filled or transferred through so-called "pipeline centers." It is crucial to ensure the correct pipes and connections are used, as incorrect container placement could lead to catastrophic consequences. Therefore, a consistent identification and monitoring system is essential near the piping connection system. A transponder should be present at each hose connection on the pipe side, and a reader should be located at the other end of the connection. The control system reads the information in the code and controls the opening of the correct pipeline valve. This approach can also be applied to the maintenance and repair of process equipment. During maintenance, RFID (Radio Frequency Identification) acts as an electronic tag, improving the preparation of necessary maintenance components, the repair of parts and machine tools, reducing downtime for process equipment maintenance, monitoring product recalls, and enabling regular maintenance of process equipment and components according to the company's safety production technical specifications, while maintaining accurate records.
Many resource management systems require data from instruments installed on process equipment. However, due to the harsh working environment in chemical plants, this data is often difficult to read on-site, such as when instrument nameplates are scratched or covered by thick layers of dirt. Particularly serious is the fact that these instruments are installed in equipment requiring strict monitoring, where the requirements for inspection and recording are extremely high, such as in environments with flammable and explosive safety precautions or in structures with protective devices. To enable process equipment operators to accurately perform their duties, they can use electronic aids, such as RFID (Radio Frequency Identification) instruments, to perform these checks, thus assisting the enterprise resource management system.
In production conditions with requirements for personnel safety and health protection as well as product safety protection, RFID (Radio Frequency Identification) technology is an important tool for accessibility detection and operator verification. It can clearly indicate whether someone is active in a hazardous area.
Another interesting application area is environmental monitoring. By integrating a sensor, such as a temperature sensor, into an RFID chip, it's possible to monitor the entire cooling chain of a product. Any temperature differences are recorded and can be read at any time.
There are many more possibilities for the application of RFID (Radio Frequency Identification) technology, and perhaps you can list one or two examples. Have you used RFID technology?
