UHF RFID systems use radio signals for tag reading, writing and energizing. UHF stands for Ultra High Frequency, i.e. 865 — 868 MHz in Europe (the ‘ETSI’ region) as well as in many other countries.
The systems are directional with a high-capacity zone, and all tags that pass in front of an antenna are quickly (up to about 200 km/h) read also at large distance (up to about 10 m).
Tags are ‘passive’, i.e. without batteries; no down-time because of empty tag batteries, nor willl there be a tag recycling issue.
Avieco's system complies to ISO 18000-63 (earlier called -6C), also called Gen2, C1G2 and more. ISO-compliance means that equipment from different manufacturers are compatible with one another. The Gen2 standard is today widely accepted for use in logistics, parking, tolling, manufacturing and other applications.
Avieco-supported readers have a voltage-tolerant 9-36 Vdc power supply, and come with a robust metal housing. They comprise traditional interfaces such as Ethernet, RS232 and I/O ports, and feature an API from the manufacturer.
With our firmware in the reader, host(s) can receive data in specific formats like XML, CSV or other. Settings can be updated via TCP and the IP address can be obtained by DHCP or set to static. Readers can e.g. be a truly ‘two-readers-in-one’ unit for multiple TCP server (or client) connection, and events can be NTP-server synchronized and reported with ms precision.
Time-, input- and other filtering can be included to block unwanted reads, a built-in log can protect recorded events against disturbances, and, to further enhance reliability, self-test and keep-alive functions have been implemented.
Avieco RFID is primarily designed for identification of large and valuable objects, e.g. to provide automatic services such as;
– Granting access via tags to open barriers, doors, gates and the like.
– Guide the tag holder where to go via a visual display, green/red lights etc.
– Direct tagged objects by automatic routing, e.g. in a factory flow-line.
– Track and report objects for decisions and/or database updating.
– Assess or analyze objects, e.g. by weighing a truck or classification of a car.
– Perform financial transactions related to tag reading, such as parking fee debiting.
The main benefit with RFID is often to reduce capital tie-up in complex processes. This is achieved e.g. through improved logistics planning and higher system up-time. Other reasons may be higher safety and stronger security in the served applications. Pay-back time is short.
