Monitoring the area between the platform screen door and the train door

          Platform screen doors increase passenger safety. Falling onto the track or moving into the track area is reliably prevented. Half-height platform screen doors (APGs) are used outdoors for safeguarding purposes, and can also be used for partially-covered platforms. In the worst case scenario, persons can be caught between the train door and the platform screen door. Before the train departs, this must be reliably signaled to the driver to prevent the train from starting. The LMS5xx 2D LiDAR sensor is installed over the platform edge, which also protects from vandalism at the same time. Thanks to the large range, a single sensor can monitor up to three platform screen doors at one time. Combined with the Flexi Soft safety controller as well as specific, integrated and external diagnostic measures, a defined safety level can be achieved. This supports individual operating licenses from a government agency or notified body.
