RFID technology, with its uniqueness, strong anti-interference, fast recognition, and intelligent identification characteristics, provides intelligent and informatized management solutions for these industries, realizing a new type of weighing smart management mode that is efficient, accurate, fast, and cheat-proof.

Unattended RFID Smart Weighing Management System Technology

Based on RFID technology, unattended smart weighing management systems can achieve automatic vehicle recognition and informatized management, improve traffic efficiency and safety, record vehicle entry and exit data, provide scheduling convenience for management personnel, reduce their workload, effectively prevent fee loopholes. The smart weighing management system utilizes long-distance RFID technology to automatically identify vehicles and merge the collected vehicle information into the weighing management system. This system can increase vehicle passing speed by 3-4 times, prevent economic losses caused by human fraud through automatic vehicle number recognition and precise measurement.

After system implementation, it significantly reduces the workload and human error rate of staff, enhances the transparency of management processes, and promotes the enterprise’s informatization process. A complete RFID management system consists of a reader, electronic tags, and application software system. The working principle involves the reader emitting wireless radio wave energy at a specific frequency to the tag, driving the tag circuit to send out internal data, then the reader receives and interprets the data, sending it to the application program for corresponding processing.

Unattended RFID Smart Weighing Management System Technology

Products derived from RFID technology can be broadly categorized into two types: passive RFID products and active RFID products.
1. Passive RFID products are one of the earliest and most maturely developed products with wide market applications. Its main operating frequencies include low frequency 125KHZ, high frequency 13.56MHZ, and ultra-high frequency 915MHZ. Low frequency 125KHZ is mainly used for canteen meal cards, membership cards, access cards, etc., while high frequency 13.56MHZ is widely used in public transport cards, library borrowing cards, etc. Ultra-high frequency 915MHZ has many advantages such as long-distance contactless reading, multi-tag anti-collision reading, fast identification speed, and the ability to identify fast-moving objects, thus being increasingly applied in IoT applications.

2. Active RFID products have gradually developed in recent years, with main operating frequencies including ultra-high frequency 433MHZ, microwave 2.45GHZ, and 5.8GMHZ. They have significant applications in the field of automatic long-distance identification, such as smart prisons and home-school communication. The RFID products used in current unattended weighing systems belong to passive RFID, operating at ultra-high frequencies within the range of 900-960MHZ, widely used in power plants, coal mines, non-ferrous metal mines, landfills, freight yards, and other units.
