发明名称 Systems and methods for determining functionality of an automatic door system
摘要 Automatic door systems and methods capable of determining proper functionality thereof are provided. The door systems are provided with a healthcheck module which automatically determines functionality of the door system by initially monitoring a first output signal provided by a first sensor and a second output signal provided by a second sensor. More specifically, the healthcheck module correlates the first output signal with the second output signal and operates one or more doors of a door system according to the correlation. The healthcheck module then monitors the second output signal provided by the second sensor to determine the ability of the one or more doors to close, and determines functionality of the door system accordingly.

主权项 1. A method for determining functionality of an automatically closing door system, comprising the steps of: monitoring an obstruction signal output by a first sensor configured to detect an obstruction in a pathway of a door of the door system, the obstruction signal corresponding to one of at least three states including a normal state, a first abnormal state and a second abnormal state; closing the door at a first speed if the obstruction signal corresponds to the normal state; closing the door at a second speed if the obstruction signal corresponds to any one of the first and second abnormal states, the second speed being slower than the first speed, the first abnormal state corresponding to a consistently active obstruction signal and the second abnormal state corresponding to a consistently inactive obstruction signal; monitoring a door position signal output by a second sensor configured to detect a current position of the door, the door position signal corresponding to one of at least three states including a closed state, an open state and a blocked state; determining if the first sensor is malfunctioning if the obstruction signal corresponds to the first abnormal state and the door position signal corresponds to the closed state, or if the obstruction signal corresponds to the second abnormal state and the door position signal corresponds to the blocked state; and declaring the door system as malfunctioning if the first sensor is malfunctioning.
