Abstract

A system is provided for assessing a condition of a tire. The system includes first and second individual modules, a data transmission gateway, and a collaboration device. The first and second individual modules are for assessing the condition of the tire. Each of the first and second individual modules includes a housing, which is structured to be placed on a ground surface, and a data transmitter. The housing includes at least one detector arranged to enable a parameter of the tire to be assessed as the tire passes over the housing. The data transmission gateway is structured to transmit data between the first and second individual modules and a remote database. The collaboration device is structured to enable data from the first individual module to be used collaboratively with data from the second individual module.

Claims

1. A system for assessing a condition of a tire, the system comprising:

first and second individual modules structured to assess a condition of a tire, each of the first and second individual modules including;

a housing structured to be placed on a ground surface, the housing containing therein at least one detection device that enables a parameter of the tire to be assessed as the tire passes over the housing, and

a data transmitter;

a data-transmission gateway structured to transmit data between the first and second individual modules and a remote database; and

a collaboration device structured to enable data from the first individual module to be used collaboratively with data from the second individual module.

2. The system according to claim 1, wherein the first and second individual modules are positioned adjacent to each other.

3. The system according to claim 1, wherein the collaboration device includes a clock synchronizer structured to synchronize internal clocks of the first and second individual modules.

4. The system according to claim 1, wherein the collaboration device includes a time adjuster.

5. The system according to claim 1, wherein each of the first and second individual modules includes an RFID chip reader.

6. The system according to claim 1, wherein the at least one detection device of each of the first and second individual modules includes at least one sensor that uses a magnetic field source.

7. The system according to claim 6, wherein the first and second individual modules and the sensors of the first and second individual modules are positioned in such a way that a distance between two adjacent sensors of the first and second individual modules is constant regardless of whether the two adjacent sensors are both installed in a same one of the first and second individual modules or are separately installed in a different one of the first and second individual modules.

8. The system according to claim 1, wherein the remote database stores information indicative of a positioning of the first and second individual modules relative to each other.

9. The system according to claim 1, wherein the collaboration device includes a mechanical device.

10. The system according to claim 1, wherein the collaboration device reconstructs a complete measurement from partial measurements taken on a same tire.
