Car Body Detection in Automobile Production

End-to-end use of RFID for automobile identification

Digital production and logistics in the automotive sector require the availability of information on every single vehicle at any time. Identification number, current production area, body design, painting, engine and equipment must be accessible reliably and automatically. Autonomously operating systems represent the greatest challenge here since they normally use different identification technologies, thus significantly restricting the networkability of the production areas. Some vehicle information is still even documented on paper. There is no central acquisition of vehicle information so that seamless cross-system vehicle identification is not possible. Furtheremore, it is also necessary to maintain the different identification technologies, thus requiring additional effort.

Your Benefits

Cross-system identification with just a single tag
Maximum detection rate thanks to polarization switching
Minimum installation effort thanks to Power over Ethernet (PoE) and integrated I/Os

The polarization switching of the Q300 guarantees maximum detection rates in metal environments
The TW865-868-Q30L50-M-HT-B332 hard tag contains the process and component data of the entire production
The TW860-960-L75-50-M-HT-B42 high temperature label accompanies the vehicle right up to shipment

Cross-system identification with just a single tag

At the first production step in the body construction area, each vehicle is already fitted with a particularly heavy-duty RFID tag such as the TW865-868-Q30L50-MHT-B332, which is suitable for direct mounting on metal. The durable hard tag based on a PCB is fitted on the rear of the car body and accompanies the vehicle from the first production step to the paintshop, to assembly right through to order preparation and shipment. The high-temperature tag features a 56-byte EPC memory for tracking long serial numbers (such as VIN) and an extensive freely usable memory of 256 bytes for chronologically logging the production process and components right through to final assembly.

Standardized data for smart production

The hard tag enables seamless digitalized production and logistics. The data of all systems is logged centrally on the vehicle. Only one identification technology is required and only this requires maintenance. Each system can read information from the chip of the RFID transponder, and can also store new data on it. Standardized vehicle information on the tag thus ensures that vehicle information can be identified across all systems.

Maximum tag detection rate

A Q300 RFID UHF reader close to the relevant workstation provides the maximum tag detection rate. Its polarization switch ensures that tags can be detected on several polarization planes and thus provides reliable tag detection in any position. Customers are spared the need for complex algorithms in the middleware or mechanical measures to ensure the detection rate. The Q300-CDS UHF reader can be used in the three Ethernet networks, Profinet Ethernet/IP or Modbus TCP immediately and without any intervention by the user. This is a major benefit for international manufacturers with controllers using different networks. Even a separate power supply is unnecessary thanks to Power over Ethernet.
The Q300 RFID read/write head can be connected to controllers or other systems directly via Ethernet. No additional interface is required. This therefore minimizes the intervention required in existing applications. The flexibility of the Q300 thus increases investment security of the UHF application.
