Abstract

Systems and methods are disclosed to adapt RFID tags in a master-slave configuration and to connect them by a connector. Upon a request from a reader, the slave RFID tag will transmit via the connector data to the master RFID tag which will concatenate the latter with its own data and transmit a concatenated series of data to the reader. Such RFID tags are presented in use in a system for managing a plurality of equipment stored in a plurality of housings, as is the case for a room of IT servers. Each such slave RFID tag is fastened preferably onto a housing, contains information on the housing, and is connected to the master RFID tag preferably fastened onto the equipment stored in the housing and containing information on the equipment. A user thereby knows in a single reading information about the equipment and the housing that it occupies.

Claims

1. A management system for managing a plurality of equipment stored in a plurality of housings, the management system comprising a reader, a plurality of RFID tags of a first type, denoted slave, each comprising a transmitter and a plurality of RFID tags of a second type, denoted master, each comprising a transmitter, each housing comprising an RFID tag of one type, either master or slave, and each equipment comprising an RFID tag of the other type connected via a connector to the RFID tag of the housing in which the equipment is stored, and in that the RFID tag of the master type is configured to transmit to the reader a series of data output by the slave RFID tag to which it is connected and a series of data output by the master RFID tag, in response to a request of the reader.

2. The management system according to claim 1, wherein each housing comprises a slave RFID tag and each equipment comprises a master RFID tag.

3. A management system according to claim 1, comprising a connector on each slave RFID tag configured to receive:

the connector;

or

a free connector, denoted inhibitor, configured to be connected to the connector.

4. The management system according to claim 3, wherein each slave RFID tag comprises:

a mechanism for detecting a connection on the connector;

an inhibitor configured to deactivate the transmitter of the RFID tag, in the event of a connection being detected on the connector; and

a sender configured to send a series of data in response to a request from the reader, in the event of a connection on the connector.

5. The management system according to claim 1, wherein each master RFID tag comprises:

a receiver configured to receive, via the connector, a series of data originating from the slave RFID tag connected to the master RFID tag;

a mechanism for detecting a connection of the receiver; and

a concatenator configured to concatenate the series of data received from the slave RFID tag with another series of data into a concatenated series of data, intended to be transmitted to the reader in response to a request from the reader.

6. The management system according to claim 4, wherein at least one of the master RFID tags comprises the connector for connecting to the slave RFID tag.

7. The management system according to claim 1, wherein the connector is chosen from among a cable and a jumper wire.

8. A method for managing a plurality of equipment stored in a plurality of housings, the management method implementing a management system according to claim 1 and comprising emitting a request in the direction of a housing and of the reader receiving a series of data, the method comprising, for each housing receiving an equipment, a step of connecting the RFID tag associated with the housing:

to the RFID tag associated with the equipment stored in the housing;

or

to an inhibitor.

9. The method according to claim 8, comprising, for each equipment stored in a housing, subsequently to the step of connecting the RFID tag associated with the housing, a step of the master RFID tag concatenating a series of data received from the slave RFID tag with a series of data output by the slave RFID tag.
