1. Requirements description
If the involved items leave the warehouse without permission, an alarm will be triggered.
The items in the storage cabinet can be automatically counted at regular intervals.
2. RFID electronic tag selection
Commonly used RFID electronic tags include 900M UHF passive electronic tags and multi-frequency active RFID electronic tags.
The 900M passive RFID electronic tag has a low cost and is mainly used for inventory and identification of organized items. The main problem of the 900M UHF passive electronic tag is that it is greatly affected by the material and occlusion of the item, and it is basically impossible to read it if it is occluded. It is basically unavailable for such applications as access control.
Multi-frequency active RFID electronic tags have high cost, but have good recognition rate and are not affected by obstruction. They are very suitable for on-site monitoring and entrance and exit control applications. The battery life of the multi-frequency active electronic label is 6-8 years. It has a built-in passive electronic label, and the surface can be printed with barcode/two-dimensional code.
Considering that the main requirements for RFID management and control of the property involved are on-site monitoring (inventory) and access control, it is recommended to adopt a multi-frequency active RFID solution.
3. Point deployment
As shown in the figure, a set of RFID identification equipment is deployed at the entrance and exit, and RFID on-site monitoring equipment is deployed at the storage cabinet to achieve real-time inventory.
4. Business scenario and process description
1) Access control
When taking out the property with RFID electronic tag installed, you need to go through the formalities in the reception room to remove the RFID electronic tag and release the armed state. Loan normally.
If the RFID electronic tag reaches the doorway identification area when it is not released from the armed state, the doorway RFID identification device will give an alarm when it reads it.
If the RFID electronic label is removed illegally, the RFID electronic label and the RFID identification device will give an alarm.
2) Online inventory
The RFID identification equipment in the storage cabinet regularly reads the data of the RFID electronic tags in it to realize regular inventory.
When the RFID electronic tag is illegally removed, the RFID electronic tag and the RFID identification device will give an alarm.
