DESCRIPTION
D
ETECTION
The DIRAS cells are of the Transmitter/Receiver type. They are grouped by 8 on electronic boards. The
transmitter cells are located on the left unit, and the receiver cells on the right unit.
The program manages the passages and determines violations in relation to the cell masking sequence.
Each lane is divided into different detection zones:
The cells located on either side of the obstacles define a security zone with a configurable length. This zone
ensures the safety of passengers by prohibiting the opening or closing of the obstacles when a passenger
comes too close to them (regardless of whether the user is authorized or not).
By extending the security zone, the safety of the passenger takes priority over the anti-fraud protection.
By reducing the security zone, the anti-fraud protection takes priority over the safety of the passenger.
In PRM mode, detection is inhibited: anti-fraud detection is deactivated to reduce the number of false alarms
due to atypical images of passengers with wheelchairs, bikes, pushchairs, etc. A simple detection mechanism
is used to prevent the obstacles from closing on the passengers or their luggage
