Abstract

A remote control door closure operating system is based on a central server with a backend database identifying a collection of controllable doors and a plurality of authorized users and corresponding credentials. A door interface unit is adapted to communicate with an authorized user to supply a live video stream of a respective door and to execute door opening and closing commands from the authorized user. A mobile device has a user application program configured to interact with the central server and door interface unit in order to 1) obtain configuration data, 2) authenticate the authorized user, 3) receive the live video stream, and 4) initiate the door opening and closing commands. Safe operation of the door opening/closing operation is encouraged by maximizing use of video surveillance before and during door operations and by conducting separate security authentications for video streaming and for door operation requests.

First claim

What is claimed is:

1. A remote control door closure operating system comprising:
a door controller unit adapted to connect to a door actuator for operating the door closure and to a video camera for obtaining a view of the door closure; and
a central server, wherein the central server and the door controller unit are adapted for network communication with each other and with a mobile device operating a user application, wherein the central server responds to a user of the mobile device to authenticate the user, and wherein when the user is validly authenticated then the central server is configured to enable access for the user application to a video stream from the door controller unit by opening a port in a network firewall operating in the door controller unit and configured to identify the opened port to the user application;
wherein the door controller unit is configured to receive a request from the user of the user application for initiating a door operation, and wherein the door controller unit is configured to contact the central server to authenticate validity of the request based on an identity of the user before initiating the door operation.

2. The system of claim 1 wherein the door controller unit monitors transmission of the video stream during execution of the door operation, and wherein the door controller unit halts execution of the door operation in the event of detecting that transmission of the video stream has failed.

3. The system of claim 1 wherein the door controller unit monitors an elapsed time during execution of the door operation, and wherein the door controller unit halts execution of the door operation in the event that the elapsed time exceeds a predetermined threshold.

4. The system of claim 1 further comprising a backend database configured to identify a collection of controllable doors and a plurality of authorized users and corresponding credentials, wherein the validity of the request depends on stored permissions of the identified user for opening and closing the door closure.

5. The system of claim 4 wherein the stored permissions of the identified user include times of day or days of the week when access to respective door operations is authorized.

6. The system of claim 4 wherein the backend database resides within the central server.

7. The system of claim 1 further comprising a backend database configured to identify a collection of controllable doors and a plurality of authorized users and corresponding credentials, wherein the central server is configured to receive idle messages from the user application when a request for a door operation is not initiated by the user, wherein the central server is configured to receive operating messages from the user application when the user application determines that a request initiated by the user is in progress, wherein a request status is stored in the backend database according to the idle messages and the operating messages, wherein the door controller unit retrieves the stored request status from the backend database when it executes a requested door operation, and wherein the door controller unit halts an executing door operation if the stored request status fails to match an actual status.

8. The system of claim 1 wherein the door controller unit has a non-video mode, wherein when receiving a request from the user for initiating a door operation and the request is validated by the central server then the door controller unit determines a proximity between the mobile device and the door closure, and wherein the door controller module initiates the requested door operation only if the proximity is within a predetermined proximity threshold.

9. The system of claim 8 wherein the predetermined proximity threshold is a distance.

10. A method of remote monitoring and operation of a door closure, comprising the steps of:
configuring a backend database containing address data of a plurality of door controller units each associated with a respective door closure, a plurality of authorized users of respective doors, and corresponding user credentials and permissions;
launching a user application on a mobile device of a user;
conducting network communication between the user application and a central server to authenticate the user, wherein the central server accesses the backend database to obtain the corresponding user credentials;
conducting network communication between the central server and the door controller unit to open a video port in a network firewall operating in the door controller unit;
conducting network communication between the central server and the mobile device to identify the opened video port to the user application;
capturing video data showing the door closure from a video camera connected to the door controller unit;
streaming the video data via the opened video port to the mobile device for presentation to the user;
conducting network communication between the user application on the mobile device and the door controller unit to transmit a request from the user for initiating a door operation;
conducting network communication between the door controller unit and the central server to authenticate validity of the request based on an identity of the user; and
initiating the door operation if validity of the request is authenticated.

11. The method of claim 10 further comprising the steps of:
monitoring transmission of the video stream during execution of the door operation; and
halting execution of the door operation in the event of detecting that transmission of the video stream has failed.

12. The method of claim 10 further comprising the steps of:
monitoring an elapsed time during execution of the door operation; and
halting execution of the door operation in the event that the elapsed time exceeds a predetermined threshold.

13. The method of claim 10 wherein the validity of the request depends on stored permissions of the identified user for opening and closing the door closure.

14. The method of claim 13 wherein the stored permissions of the identified user include times of day or days of the week when access to respective door operations is authorized.

15. The method of claim 10 wherein the backend database resides within the central server.

16. The method of claim 10 further comprising the steps of:
transmitting idle messages from the user application to the central server when a request for a door operation is not initiated by the user;
transmitting operating messages from the user application to the central server when the user application determines that a request initiated by the user is in progress;
storing a request status in the backend database according to the idle messages and the operating messages;
the door controller unit retrieving the stored request status from the backend database when it executes a requested door operation; and
halting an executing door operation if the stored request status fails to match an actual status.

17. The method of claim 10 with a non-video mode, comprising the steps of:
determining a proximity between the mobile device and the door closure when a request from the user for initiating a door operation is validated by the central server; and
initiating the requested door operation only if the proximity is within a predetermined proximity threshold.

18. The method of claim 17 wherein the predetermined proximity threshold is comprised of a distance.
