In general, three main aspects need to be considered to achieve a balance point for an RFID application. They are:
· The distance between the label and the head;
· The speed at which objects can pass in front of them;
· Data transfer rate.
Although RFID system manufacturers offer some sophisticated formulas, there are online configurations available that allow users to mimic their applications and find optimal settings.
Like many innovative concepts in the field of automation control, the automotive industry has become one of the key industries for the development of RFID applications driven by the consumption of personalized cars.
Today, consumers can determine exactly what will fit in the car they buy. This makes it necessary to mark each vehicle with information about individual characteristics that needs to be matched to the vehicle to some extent, providing transparency for each time period throughout the manufacturing process.
For automotive manufacturing that uses almost all of the classic manufacturing processes, the challenges are unique. In addition to mechanical engineering, factors that may be encountered include transportation technology, processing technology, logistics, and stamping and general metalworking techniques. These techniques add more difference to the internal associated process, so you'll run into more complex situations.
RFID applications in the automotive industry
Data carriers or tags that can withstand high temperatures are an important added value for systems offered to automotive manufacturers. They are also increasingly used in the process of coating curing, in which data carriers can be used because they can pass through the furnace on the vehicle rails. These data carriers can operate at temperatures of 200 degrees Celsius and do not require cooling prior to read and write operations.
A good system will provide tags with EEPROM and FRAM memory, which can provide almost unlimited number of read and write operations. Many traditional RFID systems only have the ability to read and write tags statically, but better systems can perform fast read and write, typically at a rate of 0.5 milliseconds per byte.
For early system developers, producing a read/write head with a usable sensing range is a major challenge. However, it has now become possible to use a head with a sensing range of 500 mm.
