Abstract

A system and method for interfacing a destination entry system with existing security infrastructure of a space. The destination entry system may include at least one destination entry device configured to receive a destination request from a user and an interface device to facilitate communication between the destination entry system and a security system). The interface device may be configured to receive credentials of the user from the security system, co-relate the credentials with areas within a space that the user is authorized to access, identify which one of the at least one destination entry device originated the destination request from the user and communicate the authorized areas and the identified one of the at least one destination entry device to the destination entry system.

First claim

What is claimed is:

1. A destination entry system, comprising:
at least one destination entry device configured to receive a destination request from a user;
an interface device to facilitate communication between the destination entry system and a security system, the interface device configured to receive credentials of the user from the security system, co-relate the credentials with areas within a space that the user is authorized to access, identify which one of the at least one destination entry device originated the destination request from the user and communicate the authorized areas and the identified one of the at least one destination entry device to the destination entry system;
at least one switch in at least indirect communication with the interface device, each at least one switch associated with one of the areas within the space that are accessible, wherein an unsecured landing is converted to a secured landing by changing status of a switch associated with a landing to be converted.

2. The destination entry system of claim 1 , wherein the interface device includes an input/output interface unit configured to receive the credentials of the user at least indirectly from the security system.

3. The destination entry system of claim 2 , wherein the input/output interface unit transfers the credentials of the user to a processing unit within the interface device.

4. The destination entry system of claim 1 , wherein the interface device further includes a message processing system configured to communicate at least indirectly with the destination entry system, the message processing system configured to generate messages identifying the authorized areas within the space.

5. The destination entry system of claim 4 , wherein the message processing system generates one message for each one of the at least one destination entry device in each of the destination request from the user.

6. The destination entry system of claim 1 , wherein the interface device communicates with the destination entry system via Ethernet.

7. The destination entry system of claim 1 , further including at least one contact in at least indirect communication with the security system and the interface device, each of the at least one contact associated with one of the areas within the space that are accessible.

8. A method of managing elevator traffic, the method comprising:
receiving a destination request from a user on a destination entry system;
determining by an interface device areas within a space that the user is authorized to access; and
assigning an elevator car by the destination entry system to the user if the destination request is to one of the areas within the space that the user is authorized to access;
wherein an unsecured landing is converted to a secured landing by changing status of a switch associated with a landing to be converted, the switch in at least indirect communication with the destination entry system.

9. The method of claim 8 , wherein receiving the destination request comprises determining by the destination entry system if the destination request is to a secured landing or an unsecured landing.

10. The method of claim 9 , wherein if the destination request is to the unsecured landing, a destination entry device of the destination entry system assigns the elevator car ( 8 - 18 ) to the user without asking for credentials of the user.

11. The method of claim 9 , wherein if the destination request is to the secured landing, the destination entry system requires the user to present credentials to a security system before assigning the elevator car to the user.

12. The method of claim 11 , wherein determining the areas within the space that the user is authorized to access comprises closing at least one contact when the credentials of the user are presented to the security system.

13. The method of claim 8 , wherein determining the areas within the space that the user is authorized to access comprises identifying a destination entry device of the destination entry system that originated the destination request.

14. The method of claim 13 , wherein determining the areas within the space that the user is authorized to access comprises generating a message to the identified destination entry device that originated the destination request, the message identifying the areas that the user is authorized to access.

15. An elevator system, comprising:
at least one group elevator system having a plurality of elevator cars; and
a destination entry system in communication with the at least one group elevator system, the destination entry system having a destination entry device configured to receive a destination request from a user; and
an interface device configured to receive the credentials from a security system, identify floors within a building that the user is authorized to access, identify the destination entry device that originated the destination request and generate a message to the destination entry system indicating the floors that the user is authorized to access;
wherein the interface device is in at least indirect communication with at least one switch, each of the at least one switch associated with at least one floor within the building that is accessible, wherein an unsecured landing is converted to a secured landing by changing status of a switch associated with a landing to be converted.

16. The elevator system of claim 15 , wherein the interface device is configured to integrate with existing security infrastructure of the building.

17. The elevator system of claim 15 , wherein the interface device includes a processing unit that identifies the floors that the user is authorized to access and the destination entry device that originated the destination request, the interface device also including a message processing system that generates the message for the destination entry system indicating the floors that the user is authorized to access.

18. The destination entry system of claim 1 , wherein the at least one switch comprises and electromechanical switch.
