Abstract

The invention relates to communication technology. Use of the invention allows to check the location of equipment in telecommunication racks. This technical result is achieved by steps of: providing the rail of rack with lengthy antenna connected to an RFID interrogator; installing on the rail sensors of location that change their state when equipment is mounted in the rack; providing said equipment with RFID tags. When equipment is set into the rack the equipment and its location is identified correlating changing of the RFID tags replay signal and changing of location sensors state.

Claims

1. A system for checking the location of equipment, comprising:

a rack with a rail for securing in place equipment;

at least one computer system;

at least one RFID interrogator connected to said computer system;

at least one unit of equipment is intended to install into said rack and provided with an RFID tag which tag contains the identifier of said unit of equipment;

characterized in that the system

comprises a lengthy near-field antenna connected to said RFID interrogator and located at least partially along said rail;

comprises at least one sensor of equipment location which sensor correlates with a part of said rail and changes its state when said unit of equipment is located at said part of rail; and

said RFID tag changes its reply signal perceived by said RFID interrogator when said unit of equipment is placed in said rack;

said computer system determines the part of said rail where said unit of equipment is located and identifies said unit of equipment correlating the change of said sensor/sensors signal/signals and the change of replay signal of said RFID tag perceived by said RFID interrogator which changes are nearest by time.

2. The system of claim 1, wherein said sensor of equipment location comprises an RFID tag.

3. The system of claim 2, wherein said sensor of equipment location comprises a switch which switch changes electrical parameters of the antenna of said RFID tag.

4. The system of claim 3, wherein said switch is a magnetic controlled switch.

5. The system of claim 1, wherein said antenna is a radiating coaxial cable.

6. The system of claim 1, wherein said antenna is a loop antenna where one long side of said loop is located along said rail.

7. The system of claim 1, wherein said RFID interrogator has several antennas connected to said RFID interrogator through an internal or/and external multiplexer.

8. The system of claim 1, wherein said RFID interrogator feeds signal to said antenna when the door of said rack is open.

9. The system of claim 1, wherein said RFID interrogator feeds signal to said antenna when a human is near said rack.

10. The system of claim 1, wherein said antenna is located along more than one rail.
