Revolutionizing Industrial Internet: The Power of LF RFID Technology

With the rapid development of the Industrial Internet, low-frequency RFID (Radio Frequency Identification) technology has been increasingly applied in industrial fields. Low-frequency RFID technology mainly operates in the frequency band of 30 kHz to 300 kHz, offering advantages such as strong penetration, robust anti-interference capabilities, and suitability for metal environments. This article will introduce the working principle of low-frequency RFID technology and demonstrate its prac

tical application in the Industrial Internet through a specific project case.

Working Principle

A low-frequency RFID system consists of three components: tags, readers, and antennas. The tags contain embedded microchips and antennas for storing and transmitting data. The reader emits low-frequency electromagnetic waves through its antenna. When the tag enters the working range of the reader, its antenna receives the electromagnetic waves and converts them into electrical energy, thereby activating the chip. The tag's chip modulates and reflects the stored data back to the reader, which then receives and demodulates this data to achieve information reading.

The reading distance of low-frequency RFID is usually between a few centimeters to one meter, making it suitable for scenarios requiring close-range, high-accuracy data collection. Additionally, low-frequency RFID has strong penetration capabilities in metal and liquid environments, ensuring stable performance in complex industrial settings.

Project Case

Take an automobile manufacturing plant as an example, which introduced low-frequency RFID technology for tracking and managing workpieces on the production line. Traditional manual recording and barcode scanning methods were inefficient and error-prone, unable to meet the demands of modern production management.During the project implementation, engineers installed low-frequency RFID readers at key process nodes and attached low-frequency RFID tags to the workpieces. As the workpieces moved through different stages of the production line, the readers automatically read the information from the tags and transmitted the data in real-time to the central management system. This allowed production line managers to monitor the production progress, location, and status of each workpiece in real-time, ensuring efficient and accurate production processes.Moreover, low-frequency RFID technology helped the automobile manufacturing plant achieve intelligent management of tools and equipment. Each tool and piece of equipment was tagged with low-frequency RFID labels. When workers used the tools or equipment, the readers recorded the usage information and updated it in the system. This not only improved the management efficiency of tools and equipment but also prevented loss and damage.

By introducing low-frequency RFID technology, the automobile manufacturing plant significantly enhanced the management efficiency of the production line, reduced the incidence of human errors, and achieved comprehensive digitization and intelligent management of the production process.

Conclusion

The application of low-frequency RFID technology in the Industrial Internet not only optimizes production line management but also enhances the efficiency of equipment and tool usage. As the Industrial Internet continues to develop, low-frequency RFID technology will play a unique role in more industrial fields, bringing more value to enterprises.
