The COPP2 system is an upgrade of COPP, extended to twelve metro stations of Paris’ 13th line. Its goal is to safely control the opening and closing of the platform screen-doors and enable the automatic turn-back of the trains at Châtillon-Montrouge (terminus of the line).
The opening of the platform screen doors
Dependability of the system
The closing of the platform screen doors
2°If, for an unknown reason, the screen doors are opened without a train at the right place or with no train at all, then, the screen doors close themselves. (If you configure them to do so.)
> An availability of the system superior to 99.9%.
> The distance between the transmitter of the train and the magnetic loop is from 0 to 284mm.
ARCHITECTURE OF THE SYSTEM
The system is made of 2 parts:
1 – An on-board system: A COPP2-Bord sub-system is installed on each train. It is connected with the material of the train and transmits the command from the train to the ground. In this COPP2-bord, we can find a record deck at the keystone of the middle wagon and a transmitter installed under this wagon.
2 – A ground part : A sub-system named “COPP2-Sol” is installed on each way and interfaced with the platform screen-doors. It receives the commands from the train, checks the necessary requirements, and if they are ok, transmits the commands to the platform screen doors. This dispositive is composed of an electronic-board, the captors and the magnetic loop between the rails.
NB : There is a magnetic loop for each platform around the train to guarantee that the right screen doors open.
At the station Châtillon-Montrouge, that subsystem is interfaced with the automatic turn-back system.
