Traditional warehouse item search relies on human memory, requiring staff to remember the locations of numerous items. Memory errors are common, leading to frequent instances of items being misplaced or incorrectly located during searches, which significantly impacts operational efficiency. With the advancement of IoT technology, traditional search methods can no longer meet the demands of modern warehouse management. There is an urgent need for a new technology to enhance warehouse search efficiency, reduce operational costs, and elevate the intelligence level of warehouse management.
The 2.4G audio-visual item-finding tag warehouse item-finding solution introduces item-finding base stations and an intelligent management system. When staff need to locate a specific item, they input the item’s name or related keywords through the warehouse management system’s interface. The warehouse management system queries the corresponding 2.4G audio-visual tag bound to the item based on the input information. The item-finding base station automatically sends an item-finding command to the tag. Upon receiving the command, the 2.4G audio-visual tag immediately activates its audio-visual alarm function, emitting flashing lights and continuous alarm sounds. Staff can quickly locate the item’s position based on the audio-visual signals.
Ⅰ. Features of the 2.4G Audio-Visual Item-Finding Tag1. Long-range transmission.
The 2.4G frequency band has excellent penetration and long transmission distance. RFID tracking tags can communicate stably in large warehouses, with an effective communication range of tens of meters, adapting to different warehouse environments and ensuring signal coverage.
2. Wide spatial coverage
Whether the warehouse layout is complex or the area is large, the 2.4G audio-visual tag can achieve wide coverage, allowing staff to receive signals from any location in the warehouse and quickly locate the item.
Warehouse Intelligent Tracking Solution
3. Reusable Tags
A single battery can last 1–3 years (depending on usage frequency). After the battery runs out, it can be replaced for reuse. After locating the item, the sound and light alerts can be manually turned off by pressing the button on the tag.
4. Advanced Low-Power Design
Using advanced low-power technology, the tags can operate for extended periods. The duration of the sound and light alerts can be customized, reducing energy consumption, minimizing battery replacement frequency, lowering maintenance costs, and enhancing warehouse management efficiency.
II. Features of the Item Tracking Base Station.
This solution offers two versions. The first version does not require a network connection and only needs one smartphone and one portable base station, making it suitable for small warehouses managed by a single staff member. The second version uses a network-connected fixed base station, enabling real-time data sharing and collaboration among multiple users, ideal for large warehouses managed by multiple staff members.
1. Portable Item Tracking Base Station
The portable item tracking base station is an active RFID base station device operating on the 2.4GHz frequency band. It connects to a smartphone via a data cable and, when paired with an omnidirectional antenna, enables omnidirectional read/write functionality. This product features an internal antenna installation design, offering portability, flexibility, wide identification range, high identification rate, powerful functionality, high reliability, and strong scalability. Its reading range can reach up to 100 meters in open environments.
2. Fixed-Mounted Item Tracking Base Station.The fixed-mounted item tracking base station is an active RFID base station device operating in the 2.4GHz frequency band. When paired with omnidirectional/directional antennas, it can achieve omnidirectional/directional read/write functionality. This product uses an external antenna installation method, allowing flexible configuration of various omnidirectional and directional antennas. It features a wide detection range, high detection rate, powerful functionality, high reliability, and strong scalability, with a reading range of up to 50 meters. The base station has a sleek and modern design, is compact and lightweight, and is durable and robust. The product incorporates software fault tolerance and hardware interference resistance design, enabling it to operate continuously and stably in harsh working environments for extended periods.
Ⅲ. Warehouse Item Tracking Solution Implementation
1. Tag Installation Method Selection
Install 2.4GHz audio-visual tags on warehouse items or shelf units using adhesive or hanging methods to ensure the tags are visible and do not interfere with item usage.
2. Tag Information Binding and Entry
In the warehouse management system, bind the tags to item information, including detailed details such as name, specifications, quantity, and location, to provide data support for precise searches.
3. Ensuring Tag Installation Quality
During installation, ensure that tags are securely installed and positioned accurately to avoid signal transmission blockages or false alarms caused by improper installation, which could affect search effectiveness.
4. Reasonable Base Station Layout and Site Selection
Base stations are deployed based on warehouse layout and area, with 2.4G base stations installed in elevated locations with unobstructed views to ensure coverage of all warehouse corners and avoid signal dead zones.
5. Coverage Range Planning
For medium-sized warehouses, a base station is installed every 30–50 meters, connected to the management system via wired or 4G networks to enable rapid data transmission and ensure system stability.
