FRENCH National Railways (SNCF) has begun the fleet rollout of an Internet of Things (IoT)-based solution for monitoring the status of passenger train doors.

The Avisé system has been developed as part of the DigitalSNCF programme to automatically notify traincrew if the doors of Corail coaches are not properly secured when the train is in motion.

Two sensors remotely monitor the status of each door, illuminating a lamp in a vestibule cabinet if the door is properly secured. The status of the lamp is transmitted via a communications module to SNCF’s IoT platform, which compares the position of all doors of the train and issues a smartphone alert to the traincrew if it detects an anomaly. This enables unsecured doors to be quickly identified.

SNCF plans to install Avisé on 350 Corail vehicles, which are used on Intercités services.
