Introduction
RFID is called Radio Frequency Identification. It is an automatic identification method which relying on storing and remotely retrieving data using RFID devices. RFID system consists of three components: antenna, transceiver and transponder. Data stores in the transponder which also called RFID tag. Transceivers read and write data from the RFID tags through the antenna. The significant advantage of RIFD is non-contact and the responding time is fast. It can be used for machine maintenance control of an auto car park system.

Technology
RFID Machine Maintenance Control used RFID technology for maintenance purpose. For an auto car park system, pallets are common to use for storing vehicles which is conveniently to transfer the vehicle with pallets. RFID tag can be stuck on the pallet for storing information of pallets and information of parking vehicles. It is useful for maintenance and system management.

Features

• Storing Pallet Information
  The tag can be stored the information of pallet, such as starting date, total served time, total empty time, number of vehicle served, etc. Engineers can use the pallet information to estimate the time need to repair or replace the pallet.
  

• Storing Parking Information
  After a vehicle parked on a pallet, the tag can store the information of parking vehicle. Start/finish parking time, types of vehicle, license number of vehicle, etc, can be stored for system operation.
  

• Automatic Build Up Parking Data
  Once all the parking data is lost or confusion, the system can automatically scan all the tag of pallets to build up the parking database again. It can dispense human input the data into the system.
  

• Highly Efficiency
  Since the read/write speed of tag is fast, it would not affect or retard the operation of system. RFID can be read through a variety of substances such as fog, paint, crusted grime, dusty and other visually and environmentally challenging conditions, where barcodes or other optically read technologies would be useless.
