Embodiment Construction
[0067] for Figure 1 to Figure 3 Corresponding parts in , use the same reference numerals.
[0068] figure 1 The system 100 shown comprises a transponder device 50 , ie an electronic tag assigned to a valuable item, and two monitor devices 10 , 20 assigned to this electronic tag 50 .
[0069] Each monitor device 10 , 20 is based on short-range radio frequency communication and includes a transmitting unit 18 , 28 for periodically transmitting at least one request 40 , 42 (ie a ping message) to the electronic tag 50 .
[0070] Instead the tag is designed to transmit at least one response 60 , 62 , ie a return message, to the monitor device 10 , 20 that has pinged ( 40 , 42 ) the electronic tag 50 .
[0071] As an exemplary embodiment, figure 1 A series of messages 40, 60 and 42, 62 between tags belonging to two co-custodians of valuables are shown. Each supervisor has one of the monitor devices 10, 20 which periodically sends a "ping" message 40, 42 to the tag 50 attached t...

Abstract
In order to further develop a system (100) as well as a method for protecting at least one item to be secured, for example at least one piece of luggage, the system comprising at least one transponder device (50), in particular at least one electronic tag, being assigned to the item, and at least one monitor device (10, 20), in particular being based on short range radio frequency communication, with at least one transmitting unit (18, 28) for transmitting and / or for broadcasting and / or for multicasting, in particular periodically, at least one request (40, 42) to the transponder device (50),in such way that the monitor device (10, 20) can be carried with him by at least one user and that at the same time it can be discovered whether the item remains nearby the respective monitor device (10, 20), it is proposed that the transponder device (50) comprises at least one processing unit (52) for determining the number (N) of monitor devices (10, 20) being arranged within the range, in particular within the receiving and / or transmitting range, of the transponder device (50), and having transmitted and / or having broadcasted and / or having multicasted its respective request (40, 42) to the transponder device (50), within a certain time interval, and that the transponder device (50) is designed for transmitting and / or for broadcasting and / or for multicasting at least one response (60, 62) comprising the determined number (N) of monitor devices (10, 20) to the respective monitor device (10, 20) having transmitted and / or having broadcasted and / or having multicasted its respective request (40, 42) to the transponder device (50).
Description
technical field [0001] The present invention relates to a system for securing at least one item, such as at least one piece of luggage, the system comprising: [0002] - at least one transponder device assigned to the item, in particular at least one electronic tag, and [0003] - at least one monitor device, in particular a monitor device based on short-range radio frequency communication, having at least one transmitting unit for transmitting and / or broadcasting and / or multicasting at least one request to the transponder device, in particular with to periodically transmit and / or broadcast and / or multicast at least one request to the responder device. [0004] The invention further relates to a method for securing at least one item, such as at least one piece of luggage. Background technique [0005] Securing belongings can be a difficult job for travelers who need to be constantly on the lookout for any luggage left behind or who have been the victim of theft. Bags may ...
