AI Technical Summary

Technical Problem

Existing systems for checking the integrity of guided vehicles, such as trains or subways, are complex and inflexible, especially during reconfigurations like adding or removing cars, and require a simpler and more adaptable solution.

Method used

A system comprising beacons, amplifiers, and a central processing unit (CPU) that uses wireless signals with unique identifiers, where beacons are installed on cars, amplifiers extend the signal range, and the CPU determines the presence of the first beacon, allowing easy adaptation to vehicle composition changes.

Benefits of technology

The system provides a flexible and efficient method to check vehicle integrity by easily adding or removing beacons and amplifiers, ensuring the signal reaches the CPU, thus accommodating reconfigurations without complex installations.

Abstract

System and method for automatically checking an integrity of a guided vehicle Abstract The present invention concerns a system (100) and a method for checking an integrity of a guided vehicle (200), said guided vehicle (200) comprising a first car (FC), a last car (LC), and optionally one or several intermediate cars (IC) located between the first car (FC) and the last car (LC), the system (100) comprising: - at least one beacon (110), each beacon (110) being configured for wirelessly broadcasting a signal comprising a unique identifier enabling an identification of the beacon (110) broadcasting said signal, wherein at least one beacon (110), hereafter called first beacon (FB), is configured for being installed on the first car (FC); - optionally, one or several amplifiers (120) for extending a transmission range of a received beacon signal so that it reaches a gateway (130), each amplifier being configured for being installed on one of said intermediate cars (IC); - said gateway (130) configured for receiving any beacon signal, said gateway (130) being configured for being installed on the last car (LC) and for transmitting any received beacon signal to a central processing unit (140), hereafter CPU; - said CPU (140), connected to the gateway (130), and configured for determining a presence of the first beacon (FB) by identifying, in the beacon signals transmitted by the gateway (130), the unique identifier of the first beacon (FB). Figure 1 System and method for automatically checking an integrity of a guided vehicle Abstract The present invention concerns a system (100) and a method for checking an integrity of a guided vehicle (200), said guided vehicle (200) comprising a first car (FC), a last car (LC), and optionally one or several intermediate cars (IC) located between the first car (FC) and the last car (LC), the system (100) comprising: - at least one beacon (110), each beacon (110) being configured for wirelessly broadcasting a signal comprising a unique identifier enabling an identification of the beacon (110) broadcasting said signal, wherein at least one beacon (110), hereafter called first beacon (FB), is configured for being installed on the first car (FC); - optionally, one or several amplifiers (120) for extending a transmission range of a received beacon signal SO that it reaches a gateway (130), each amplifier being configured for being installed on one of said intermediate cars (IC); - said gateway (130) configured for receiving any beacon signal, said gateway (130) being configured for being installed on the last car (LC) and for transmitting any received beacon signal to a central processing unit (140), hereafter CPU; - said CPU (140), connected to the gateway (130), and configured for determining a presence of the first beacon (FB) by identifying, in the beacon signals transmitted by the gateway (130), the unique identifier of the first beacon (FB).
