Abstract

A door control device is disclosed. In the door control device, after operation of “Full Close” in one status has been detected, obstruction occurs in a door close detection switch ON/OFF detection portion so that one event “Dcsm=OFF”, e.g. a signal (Dcsm=OFF) indicating OFF detected by the door close detection switch ON/OFF detection portion is obtained. On this occasion, operation of “ReClose” in another status is executed so that drive toward a close direction is continued by a door close control portion through a reclose command portion until another event “Dcsm=ON”, e.g. a signal (Dcsm=ON) indicating ON detected by the door close detection switch ON/OFF detection portion is obtained.

First claim

What is claimed is:

1. A door control device that opens and closes a door using a door drive portion, the door control device comprising:
a door opening and closing control portion that gives an open command to the door drive portion, a close command to the door drive portion, a reclose command to the door drive portion, and a recycle open and close command to the door drive portion, the door drive portion being
driven in response to each of the close, reclose and open commands, and
driven recyclically in response to the recycle open and close command;

a door close detection portion that detects a full close state of the door based on whether a switch is detected to be in an ON status or an OFF status; and
wherein the door opening and closing control portion is configured so that in response to the ON status transitioning, not in response to any open command to open the door being provided to the door drive portion by the door opening and closing control portion, to the OFF status, the door opening and closing control portion performs a reclose operation of giving the reclose command to the door drive portion to control the door drive portion to perform an open operation of the door and then a continuous close operation of the door until the ON status is detected.

2. The door control device according to claim 1 , further comprising:
a lock mechanism operation detection portion that detects an operation and non-operation of a lock mechanism for locking the door in a close position,
wherein when the reclose operation has been performed recyclically such that the close operation of the door has been performed recyclically a plurality of times within a predetermined time, an obstruction signal of the lock mechanism is outputted by the door control device.

3. The door control device according to claim 1 , wherein in the reclose operation, when the ON status of the switch is not detected by the door close detection switch portion when the close operation of the door is performed continuously for a time, an obstruction signal of the door close detection portion is outputted by the door control device.

4. The door control device according to claim 1 , wherein in the reclose operation, an open command operation is validated by the door control device when the close operation of the door is continuously performed due to the OFF status of the switch being detected by the door close detection portion.

5. A door control device that opens and closes a door using a door drive portion, the door control device comprising:
a door opening and closing control portion that gives an open command to the door drive portion, a close command to the door drive portion, a reclose command to the door drive portion, and a recycle open and close command to the door drive portion, the door drive portion being
driven in response to each of the close, reclose and open commands, and
driven recyclically in response to the recycle open and close command;

a door close detection portion that detects a full close state of the door based on whether a switch is detected to be in an ON status or an OFF status; and
a lock mechanism operation detection portion that detects an operation and non-operation of a lock mechanism for locking the door in a close position;
wherein the door opening and closing control portion is configured so that in response to the lock mechanism operation detection portion detecting the non-operation of the lock mechanism, the door opening and closing control portion performs a reclose operation of giving the reclose command to the door drive portion to control the door drive portion to perform an open operation of the door and then a continuous close operation of the door until the ON status is detected.

6. The door control device according to claim 5 , wherein an open command operation is validated by the door control device when in the reclose operation, the close operation of the door is continuously performed for a predetermined time due to the non-operation of the lock mechanism being detected by the lock mechanism operation detection portion.

7. The door control device according to claim 5 , wherein when the reclose operation has been performed recyclically such that the close operation of the door has been performed recyclically a plurality of times within a predetermined time, an obstruction signal of the lock mechanism is outputted by the door control device.

8. The door control device according to claim 5 , wherein in the reclose operation, the door opening and closing control portion controls the door drive portion to perform the open operation regardless of whether an ON status is detected.

9. The door control device according to claim 8 , wherein the ON status is detected when the open operation of the reclose operation is initiated by the door opening and closing control portion.

10. The door control device according to claim 5 , wherein the door opening and closing control portion controls the door drive portion to continuously perform the reclose operation until
both the ON status is detected and the operation of the lock mechanism is detected.
