Abstract

A method is presented for setting parameters of a field station equipped with an antenna for exchanging data in a contactless manner through RFID technology with electronic tags, the field station equipped with a signalling unit and equipped with electronic circuits including a memory containing at least one parameter. The invention consists in particular of updating a field station parameter as a function of the duration for which an electronic setting tag remains within the range of the field station antenna and of transmitting a signal using a signalling unit when the parameter of the field station is being updated.

Claims

1. Method for setting a value of a parameter of a field station equipped with an antenna for exchanging data in a contactless manner through inductive RFID technology with electronic tags, the field station equipped with electronic circuits including a memory containing at least one parameter, wherein in said method, the field station implements steps of:

recognizing an electronic setting tag when the electronic setting tag passes within range of the antenna,

initializing the value of the parameter of the field station at the moment when the field station recognizes the electronic setting tag,

updating the value of the parameter of the field station as a function of the duration for which the electronic setting tag remains within the range of the antenna, and

transmitting a signal using a signalling unit when the parameter of the field station is being updated.

2. The method according to claim 1, wherein the updating the value for the parameter includes incrementing the parameter at a predefined frequency for the duration for which the electronic setting tag remains within the range of the antenna.

3. The method according to claim 2, wherein the signalling unit includes a light-emitting diode emitting a flash of light each time the value of the parameter increments.

4. The method according to claim 1 or 2, wherein the method further comprises:

transmitting, using the signalling unit, a number of signals corresponding to the value of the parameter of the field station stored in the memory when the electronic setting tag is no longer within the range of the antenna of the field station.

5. The method according to claim 4, wherein the signalling unit includes a light-emitting diode emitting flashes of light at regular intervals, the number of such flashes being equal to the value of the parameter of the field station stored in the memory.

6. The method according to claim 1, wherein the step of recognizing the electronic setting tag is carried out after the field station is powered up when an electronic setting tag comes within the range of the antenna.

7. The method according to claim 1, wherein the parameter to be updated is an address identifying the field station in a communication network.

8. System for setting a value of a parameter of a field station equipped with an antenna and with electronic circuits including a memory containing at least one parameter, the field station able to exchange data in a contactless manner through inductive technology with electronic tags, the system comprising:

an electronic setting tag and

the field station including a recognition means for recognizing the electronic setting tag, updating means for updating the value of the parameter as a function of a duration for which the electronic setting tag remains within range of the antenna and a signalling means for transmitting a signal when the value of the parameter of the field station is being updated.

9. The system according to claim 8, wherein the updating means initializes the value of the parameter of the field station when the electronic setting tag arrives within the range of the antenna.

10. The system according to claim 9, wherein the updating means increments the value of the parameter of the field station at a predefined frequency while the electronic setting tag remains within the range of the antenna.

11. The system according to claim 10, wherein the signalling means includes a light-emitting diode emitting a flash of light each time the value of the parameter of the field station is incremented.

12. The system according to one of claims 8 to 10, wherein the signalling means transmits a number of signals corresponding to the value of the parameter of the field station stored in the memory when the electronic setting tag is no longer within the range of the antenna.

13. The system according to claim 12, wherein the signalling means includes a light-emitting diode emitting flashes of light at regular intervals, the number of such flashes being equal to the stored value of the parameter of the field station.

14. The system according to claim 8, wherein the recognition means is executed each time the field station is powered up.

15. The system according to claim 8, wherein the parameter to be updated is an address identifying the field station in a communications network.
