Abstract

A maintenance station monitors and maintains a plurality of automatic door systems at remote locations. Each door system includes a control unit for controlling the operation of an automatic door, and a self-diagnosing arrangement which operates in conjunction with the control operation of the control unit, to inspect the automatic door system for malfunctioning or broken part of the door system. When a failure is found in the automatic door system, the self-diagnosing arrangement of that door system sends information identifying that door system and information identifying the malfunctioning or broken part to the maintenance station via modems and telephones.

Claims

1. An automatic door remote monitoring system comprising:

a plurality of automatic door systems each including an automatic door and a control unit, said control unit including door control means for controlling the operation of said automatic door and self-diagnosing means for detecting a failure in components of said automatic door system, said self-diagnosing means, when detecting a failure in any of said components of the automatic door system with which said self-diagnosing means is associated, providing failure information including system identifying information identifying said associated automatic door system, malfunctioning part identifying information identifying a malfunctioning component and system state information about the malfunctioning automatic door; and

a communications system for sending said failure information from each of said control units to a maintenance station which monitors and maintains said plurality of automatic door systems;

said maintenance station determining, from said failure information sent thereto, the state of the automatic door of the automatic door system from which said failure information has been sent to said maintenance station, and sending, via said communications system, to the control unit of said automatic door system, a command to change operation of the automatic door of the automatic door system.

2. The automatic door remote monitoring system according to claim 1 wherein said system state information includes door position information about a position of said automatic door when the detected failure has occurred.

3. The automatic door remote monitoring system according to claim 1 wherein said system state information includes operating parameter information about an operating parameter of said automatic door when the detected failure has occurred.

4. The automatic door remote monitoring system according to claim 1 wherein said system state information includes maintenance information about maintenance which was provided for said automatic door system before the detected failure has occurred.

5. An automatic door remote monitoring system comprising:

a plurality of automatic door systems, each including an automatic door and a control unit for controlling said automatic door; and

a maintenance station which monitors and maintains said plurality of automatic door systems, said maintenance station sending a command to change an operating parameter of the automatic door of a particular automatic door system via a communications system to the control unit of said particular automatic door system, in accordance with a request by the owner of said particular automatic door system;

said maintenance station, when sending said command to change the operating parameter to said control unit, sending a command to cause said automatic door to temporarily perform a predetermined particular opening and closing operation so as to notify said owner of the operating parameter change;

said control unit of said particular automatic door system causing said automatic door to operate with the operating parameter as changed in response to said command, after causing said automatic door to perform said predetermined particular opening and closing operation.

6. The automatic door remote monitoring system according to claim 5 wherein each of said plurality of automatic door systems includes a sensor for sensing an object approaching the automatic door of that automatic door system, and said control unit of that automatic door system executes the command to change the operating parameter of the automatic door when said control units finds that said sensor is not sensing any object.

7. An automatic door remote monitoring system comprising:

a plurality of automatic door systems each including an automatic door and a control unit, said control unit including door control means for controlling the operation of said automatic door and self-diagnosing means for detecting a failure in components of said automatic door system said self-diagnosing means, when detecting a failure in any of said components of the automatic door system with which said self-diagnosing means is associated, providing failure information including system identifying information identifying said associated automatic door system, and malfunctioning part identifying information identifying a malfunctioning component; and

a communications system for sending said failure information from each of said control units to a maintenance station which monitors and maintains said plurality of automatic door systems;

said self-diagnosing means sending said failure information to said maintenance station through said communications system, and also providing a command to change the operation of the automatic door to said door control means, the operation to be changed being dependent on a malfunctioning component of said automatic door.

8. The automatic door remote monitoring system according to claim 7 wherein said command to change the operation of the automatic door is a command to lower the moving sped of said automatic door.

9. The automatic door remote monitoring system according to claim 7 wherein said command to change the operation of the automatic door is a command to move the automatic door to the fully opened or fully closed position thereof.
