Method and system for transferring data between at least one read/write device and at least one data memory in an identification system using transfer-time measurement for selecting received data
First Claim
1. Method for transferring data between at least one read/write device and at least one mobile data memory in an identification system with at least one mobile data memory attached to at least one object, for detecting object-related data of the at least one object, comprising:
- sending a data signal from the read/write device to the at least one mobile data memory;
returning a modulated data signal from the at least one mobile data memory to the read/write device;
determining a difference in transfer time between a received modulated data signal of a mobile data memory and the data signal of the read/write device; and
processing the modulated data signal of the mobile data memory if the determined difference in transfer time is below a predefined transfer time limit.

Abstract
A method and system for transferring data between at least one read/write device (RWD) and at least one mobile data memory (MDM). The mobile data memory (MDM) is preferably attached to an object for recording object-related status and/or process data, e.g. in a dispatch, transport and/or manufacturing system for the individual objects. According to the method, a difference in transfer time between the received data signals of a mobile data memory (MDM) and transmitted data signals of the read/write device (RWD) is determined in the read/write device (RWD) and the received data signals of the mobile data memory (MDM) are processed further in said read/write device (RWD) only if the difference in transfer time which has been determined lies within a predefined transfer time limit.

16. Identification system comprising:
-
a read write device;
a plurality of objects in motion; and
a plurality of mobile data memories correlated with said objects;
wherein said read write device is configured with at least one of hardware or software to transmit a plurality of data signals, wherein said data memories are each configured with at least one of hardware or software to return at least one of the data signals as a modulated data signal, and wherein said read write device is further configured with at least one of hardware or software to receive the modulated data signal, to determine a difference in transfer time between the at least one data signal and the modulated data signal, and to compare the determined difference with a limit value. - View Dependent Claims (17, 18, 19)
