The following description relates to elevator systems and, more specifically, to a mobile elevator request floor authorization system of an elevator system.
In the fields of physical security and information security, access control (AC) is the selective restriction of access to a place or other resource. The act of accessing may mean consuming, entering or using. Permission to access a resource is called authorization.
In a building, AC is employed to permit or prevent access to certain areas or floors by various personnel. For example, in a hotel, hotel guests may be permitted to have access to their guestrooms and public areas but not to other guestrooms or hotel offices. On the other hand, cleaning services may have access to all the guestrooms.
In any case, movement between floors in a building is often provided by way of an elevator system that is responsive to elevator requests made in elevator bays. Those elevator requests may be improper, however, as in a case in which a hotel guest or cleaning person requests travel to a floor in the hotel to which he does not have access.

These and other advantages and features will become more apparent from the following description taken in conjunction with the drawings.
The subject matter, which is regarded as the disclosure, is particularly pointed out and distinctly claimed in the claims at the conclusion of the specification. The foregoing and other features, and advantages of the disclosure are apparent from the following detailed description taken in conjunction with the accompanying drawings in which:
As will be described below, an elevator request authorization system is provided to provide smartphone users the ability to call an elevator from their smartphone. To provide security authorization functionality for smartphone users, the elevator request authorization system routes the same credential data to a security system whether the user makes an elevator request from their smartphone or by way of a radio frequency identification (RFID) card or any other known security credentialing method. That is, a smartphone user registers with a remote or first server and completes a user account setup with the same credential data that would otherwise be used in the RFID card or secure identification cases and which is programmed in an access control system (i.e., when a smartphone user registers, a building manager or security personnel for the building approves the user registration and inputs credential information for the user that is the same as what is present in the access control database). Following registration, the smartphone user makes an elevator request on their smartphone which is transmitted to the remote or first server. The elevator request is authenticated by the remote or first server and the corresponding credential data is appended to the elevator request. The elevator request and the appended credential data is then routed to a local or second server and passed to the access control system. Within the access control system, the user's authorized floors are verified based on the credential data. An elevator car assignment can then be made with an elevator car dispatched thereafter.

With continued reference to
The portable computing device 22 of the user may be provided as a smartphone, a smart watch, a tablet, a laptop computer, etc. In any case, the portable computing device 22 may have an application 220, such as an elevator request application, stored thereon for facilitating an interface between the user and the elevator system 13 of the building 10. The user initially uses the application 220 to register himself and the portable computing device 22 with the first server 21 or, in alternative embodiments, with other computing devices such as the second server 23 or with some of the components 30 of the access control system 100. For purposes of clarity and brevity, the following description will relate to the case of the portable computing device 22 being a smartphone.
The first server 21 is receptive of an elevator request of a user. The elevator request may be made and instantiated by the user through the application 220 of the portable computing device 22. Upon such reception of the elevator request by the first server 21, the first server 21 is configured to authenticate the elevator request and to append credential data thereto in accordance with a result of the authentication. The credential data is associated with access rights of the user and is established upon completion of the registration.
The second server 23 is receptive of the elevator request appended with the credential data from the first server 21 via the internet gateway 24 and passes the elevator request appended with the credential data to the components 30 of the access control system 100.
In accordance with embodiments, the components 30 of the access control system 100 receive the elevator request appended with the credential data from the second server 23 and are configured to analyze the credential data, to determine which floors of the plurality of floors 11 of the building 10 the user is authorized to visit based on the credential data and to assign an elevator car 130 to service the elevator request in accordance with a result of the determination. The components 30 of the access control system 100 are further configured to determine, using similar inputs and algorithms, which floors of the plurality of floors 11 a user generating an elevator request with an RFID card or some other form of security identification is authorized to visit.
In accordance with alternative embodiments, other computing devices described herein may be disposed and configured to complete all or a portion of the operations of the components 30 of the access control system 100. For example, either the first server 21 or the second server 23 may be disposed and configured to analyze the credential data, to determine which floors of the plurality of floors 11 of the building 10 the user is authorized to visit based on the credential data, to assign an elevator car 130 to service the elevator request in accordance with a result of the determination and to determine, using similar inputs and algorithms, which floors of the plurality of floors 11 a user generating an elevator request with an RFID card or some other form of security identification is authorized to visit.
As shown in
In accordance with embodiments, the third server 31 is configured to be receptive of the credential data, to analyze the credential data, to determine which floors of the plurality of floors 11 the user is authorized to visit based on results of the analysis of the credential data and to generate a signal S1 accordingly. This signal S1 is indicative or reflective of those floors of the plurality of floors 11 the user is authorized to access. The fourth server 32 is configured to receive the elevator request appended with the credential data from the second server 23, to direct the credential data toward and to receive the signal S1 from the third server 31.
In an event the signal S1 is inconsistent with the elevator request (i.e., the elevator request would take the user to a floor he is not authorized to access), the fourth server 32 may refuse to act on the elevator request and may issue a refuse notification to the application 220 whereby the user can be advised of the refusal.
In an event the signal S1 is consistent with the elevator request (i.e., the elevator request takes the user to a floor he is authorized to access), the fourth server 32 directs a call signal S2, which is consistent with the elevator request, toward the dispatcher unit 15. The dispatcher unit 15 then dispatches an elevator car 130 to service the elevator request and issues a car assignment signal S3 to the fourth server 32. The fourth server 32 is further configured to be receptive of the car assignment signal S3 and to issue an elevator assignment signal S4 to the application 220 whereby the user may be advised that an elevator car 130 is about to be or has been dispatched to service the elevator request.
With reference to
With reference back to
In accordance with further embodiments, the method may also include directing the credential data from the fourth server 32 to the third server 31 (205), analyzing the credential data, determining from a result of the analysis which floors of the plurality of floors 11 the user is authorized to visit based on the credential data at the third server 31 and issuing the signal S1 back to the fourth server 32 (206). At this point, in an event the signal S1 is consistent with the elevator request (i.e., the elevator request takes the user to a floor he is authorized to access), the method may also include directing a call signal S2, which is consistent with the elevator request, from the fourth server 32 toward the dispatcher unit 15 (207), dispatching an elevator car 130 to service the elevator request and issuing car assignment signal S3 to the fourth server 32 at and from the dispatcher unit 15 (208) and, upon reception of the car assignment signal S3 at the fourth server 32, issuing the elevator assignment signal S4 from the fourth server 32 to the application 220 (209).
