On the importance of RFID access control system in asset management

　　Asset management is an important part of enterprise management in various industries, such as some mechanical equipment, electronic equipment, tools and appliances. Traditional asset management methods are time-consuming and labor-intensive, information feedback is lagging, and management efficiency is low. The drawbacks of various aspects are becoming increasingly prominent and urgently need to be resolved.

　　UHF RFID technology has been widely used in the asset management of various industries such as power, banks, hospitals, etc. because of its long reading distance, strong penetrating ability, strong multi-tag recognition ability, large amount of information, and anti-pollution. Install RFID electronic tags on the assets to be managed, install RFID antennas and RFID readers at the entrance and exit, or directly use the RFID access control system, combined with the real-time monitoring platform of the back-end data center, to achieve full visibility of assets and real-time information update, which can be real-time Monitoring the use and flow of assets can realize real-time location query, equipment movement tracking records, alarms and other functions, which improves the efficiency of asset management.

　　The application advantages of the access control system combined with UHF RFID technology in asset management are mainly reflected in the following aspects:

　　1. Non-contact data collection, without manual intervention, reduces labor costs.

　　2. Real-time monitoring of asset entry and exit information, and record all assets entering and exiting. This protects the security of assets and prevents theft.

　　3. Strong ability to read multiple tags. It can identify multiple assets with RFID electronic tags at the same time, reducing time and labor costs.

　　4. Effectively avoid label misreading. The antenna of the RFID access control system uses a horizontal plane narrow beam design, the access control coverage area is accurate, there is no blind spot, and the tags inside the entrance and exit will not be misread.

　　5. There will be alarm prompts for illegal label access. When the assets with RFID tags pass through the RFID access control radiation area, the tags are activated and radiate signals to the outside. After the access control receives the tag information, it transmits it to the microprocessor. The microprocessor compares the EPC information with the EAS function setting conditions. , If the setting conditions are not met, it is an illegal label. The alarm will alarm when entering and exiting the access control, which can effectively prevent asset loss and save costs.

　　The most common problem of RFID access control with poor performance in the market is misreading and missing reading. The access control is installed at the door, and the asset equipment in the warehouse is very close to the door. Usually the antenna will read the tag inside. , Resulting in inaccurate data, so the antenna disabled by the door must be a circularly polarized narrow beam antenna, so that the radiation on the left and right sides of the door is as narrow as possible, so that the tags in the warehouse will not be misread. In addition, the problem of missing reading will cause data loss and waste of resources. Therefore, the performance and selection of RFID antennas in the access control system are particularly important. The access control system integrates a powerful circularly polarized narrow beam antenna that can effectively solve misreading, Missed reading,
