System to detect a person in a gap SIL3 (DIL)

Détection d’individus dans les lacunes (DIL)

CLEARSY was chosen by the RATP to install a person detection system (DIL). The project includes studies, development, supply, qualification, installation, trials, and putting into service the DIL system and maintenance (turnkey project).

As part of the project of complete automation of the line 1 and now the line 4 of PARIS subway (RATP), platform screen doors were installed on all the platforms of the lines.

They permit the circulation of the driverless trains. It allows a better time management and better regularity. However, the curve of some platforms creates a gap between the train and the platform. It was therefore necessary to make sure that no one fell in the gaps before closing the doors.

Our actions

The project includes studies, development, supply, qualification, installation, trials, and putting into service the DIL system and maintenance (turnkey project).
