RFID for asset management
RFID is used to label the fixed assets. By installing RFID electronic tags, RFID identification devices are installed in the entrances and exits. Combined with the real-time monitoring platform of the data center assets, the assets are fully visible and the information is updated in real time. It can monitor the use and flow of assets in real time, which is embodied in the real-time query of equipment location, equipment movement tracking records, alarms, equipment management statistics reports and other management objectives, and establish an advanced, standardized and optimized management mechanism.
RFID (Radio Frequency Identification) is mainly composed of a reading and writing device and an electronic tag. The reading and writing device and the electronic tag automatically recognize the target object through the radio frequency signal, and acquire related data, thereby realizing the recognition of the object. The collected data is transmitted to the application system platform for aggregation, analysis, and processing. The technology has the characteristics of long reading distance, strong penetrating ability, anti-pollution, high efficiency (multiple tags can be processed at the same time), and large amount of information.
Using RFID principles and features, RFID tags are installed on fixed assets such as cabinets and internal equipment, RFID identification devices are installed inside the machine room entrances and cabinets, and real-time monitoring platforms for data center assets are used to realize full visibility of assets and real-time information updates. It can monitor the use and flow of assets in real time, which is embodied in the real-time query of equipment location, equipment movement tracking records, alarms, equipment management statistics reports and other management objectives, and establish an advanced, standardized and optimized management mechanism.
What is the difference between active RFID and passive RFID?
Passive tags have no power; they are activated by electromagnetic waves emitted by the reader and then sent back to the reader. The practical range of passive tags is about 10 cm to a few meters.
Active tags have a built-in power supply and a microprocessor to perform special tasks. The data transmission range of active tags is much higher than that of passive tags; an active RFID reader can monitor all active tags within 100 meters.
What are the advantages of passive RFID?
If you use passive asset tagging technology, it can read up to four times faster than using a barcode. Users only need to carry a passive RFID reader, even if the tag is not in the line of sight can be detected. Users still need to inspect the actual location of each tag asset, the data collection process will run automatically and the error rate is very low.
What are the advantages of active RFID?
When an object is managed by an active RFID tag, the routine inventory of the object is essentially unnecessary. Active RFID tracking solutions will automatically and in real-time start asset inventory based on suitability, business and security needs.
The reader can be permanently installed (eg, office, storage room, areas with high traffic flow, exit channels, etc.) key locations to report the current status of the tagged assets in the designated area.
When to use passive RFID
Passive RFID is commonly used in the retail supply chain to improve inventory tracking and management effectiveness. Passive RFID can be regarded as a kind of “enhanced bar code”. (The longer the bar code will be used, the more the quality will be defaced, the quality of the tear, etc., and the reader and the bar code are required to be in the field of view. Within the scope). The absence of a built-in power source means that individual passive tags can be quite small and inexpensive; passive tags for commercial use can be used to be nested on sticker tags.
When to use active RFID
Active RFID systems use the “lighthouse” tag to relay their status on a regular basis. These tags are transmitted in real time and identify the tag assets immediately and continuously. Active RFID solutions are clearly superior to other passive solutions if real-time tracking is required over a large range. Active technologies have significant advantages for the management of critical assets, IT equipment, valuables, mobile and shared resources.
How do active RFID tags recognize assets?
The tag information is encoded in the form of a “license” number by a series of RF pulses; these pulse codes consisting of letters and numbers do not have any inherent meaning. The reader will decode and report on the payload status of all tags in the area being run (eg displacement, temperature, damage). Once the tag is associated with the asset, these will become important and valid information through the system software. The tag number information tells the geographic location of the system’s assets; the tag’s payload status also provides asset awareness for operational decisions.
