Main RFID System Features
Tags can store the large amount of
data (8,000 bytes max.) that is necessary for production control.
The data required for each process (process history, inspection
data, etc.) can be overwritten freely and without contact. This
promotes paperless production lines, and eliminates several factors
that lower yield within each process.
Data is distributed to lower the
burden on the host system. This cuts system development costs,
dramatically speeds up system start-ups, and enables flexibility in
making system changes. Integrating objects and data allows accurate,
error-free production, process, and quality control. Also,
up-to-the-minute data storage enables offline processing in the
event of an emergency, to drastically shorten the time required to
restore operation.
Unlike bar codes, in which "1s" and
"0s" must be distinguished, the RFID System uses highly advanced
wireless transmission technologies and protocols. The transmitted
data includes a 16-bit CRC (checksum), and burst error detection for
18 bits or more is 99.9985% min., ensuring highly reliable
communications. The system also has no mechanical parts, as there
are in raster scanning bar codes, so there is much less chance of a
malfunction or other problem.
In contrast with bar codes, the RFID
System communicates with electrical and electromagnetic signals.
This eliminates the problem of data errors or not being able to read
data due to soiling, moisture, oil, etc., on the target object.
Communication is not affected by resin, moisture, or other matter,
except for metals, positioned between the Antenna and the Tag.
Further, because the communications area is relatively large, there
is no need for extremely precise positioning of the target object,
which reduces both time and cost in mechanical design.
