At least one leaf of this door is equipped with a detection device comprising a mechanical detection device and a contactless sensor each capable of detecting a presence. The control circuit board comprises a control unit for movement of each leaf and a diagnostic unit, while means transfer, from the detection device in the direction of the diagnostic unit and the control unit, a first item of information representative of the activation state of the mechanical device, and a second item of information representative of the activation state of the contactless sensor. The diagnostic unit can identify a malfunction at least of the contactless detection device, when the first item of information has an active value while the second item of information has an inactive value. The invention allows redundancy to improve the availability of the detection device, while performing predictive maintenance for the operator, in particular a malfunction of the contactless sensor.
An access door, comprising:
(canceled)
The door according to claim 15, wherein the control unit is configured to compare the first item of information with the second item of information for a predetermined duration.
The door according to claim 15, wherein the first item of information corresponds only to the activation state of the mechanical device, while the second item of information corresponds only to the activation state of the contactless sensor.
The door according to claim 15, wherein the first item of information corresponds only to the activation state of the mechanical device or only to the activation state of the contactless sensor, while the second item of information corresponds to the activation state of one or both the mechanical device and the contactless sensor.
The door according to claim 15, in which the one or more transfer lines comprise a single transfer line configured to convey a single electrical signal carrying both the first item of information and the second item of information from the detection unit towards the control unit.
The door of claim 15, wherein the detection device and the control unit are configured to receive the first and second items of information, the control unit configured to identify malfunction of the contactless sensor responsive to the first and second items of information indicating activation of the mechanical device but an absence of activation of the contactless sensor.
