• Programming of transponders

Example: Cennection possibilities

The transponder antenna is used for localization and track guidance of Automated Guided Vehicles (AGVs) or cranes by means of tags on or within the ground (transponders). All settings or software updates important for operation can be carried out via a serial interface. As soon as a transponder is in the antenna's reading area, it is supplied with power inductively without contact and then cyclically sends its code back to the antenna every eight milliseconds at half the antenna’s transmission frequency.

The transponder is otherwise completely passive and does not require its own power supply or battery. Only one transponder at a time may be in the antenna's reading area. The antenna supplies the transponder code, a uniform linear deviation transverse to the direction of travel, and in the direction of travel the information "In front of transponder", "Crossing" and "Behind transponder".

The measuring electronics for determining the code and position are integrated in the antenna. When the Y-axis is crossed (crossing at right angles to the direction of travel), a high-precision positioning pulse (PosiPulse) with adjustable duration is output. The PosiPulse is available both as a digital output and via the telegrams of the serial and CAN bus interfaces.
