Abstract
An elevator access control system monitors a secure area, including an elevator landing, and controls an elevator system with at least one elevator car that is accessible from the elevator landing. Each elevator car of the elevator system has a door at the landing that provides access between the elevator car and the landing. The system includes an access monitoring device that detects the presence of non-authorized individuals within the secure area and produces a breach signal upon detecting one or more non-authorized individuals within or entering the secure area. Upon receiving the breach signal, an access system controller in communication with the access monitoring device initiates a security alert phase.
Claims23
An elevator access control system comprising:
- an access monitoring device operable to detect the presence of non-authorized individuals within a secure area including an elevator landing and to produce a breach signal upon a detection of one or more non-authorized individuals within the secure area;
- an access system controller in communication with the access monitoring device and configured to initiate a security alert phase upon receiving the breach signal;
- and
- an elevator system controller configured to,
- monitor each elevator car during the security alert phase to identify each elevator car having a respective door at the landing with an open door status, and
- for each elevator car with a corresponding door at the landing having or achieving an open door status during the security alert phase, allow the door at the landing to open that is at least one of:
- opening at the beginning of the security alert phase, closing and subsequently reopening at the beginning of the security alert phase, or arriving at the landing during the security alert phase to open, and prevent user operation of the respective elevator car and maintain the respective door at the landing open for a remainder of the security alert phase.
4 more elements
A method of securing an elevator access area, the method comprising:
- defining a secure area including an elevator landing providing access to an elevator system including at least one elevator car;
- monitoring the presence or entry of unauthorized individuals in the secure area;
- initiating a security alert phase upon detecting the presence or entry of one or more unauthorized individuals in the secure area;
- monitoring a status of each elevator car in the elevator system during the security alert phase to identify each elevator car havin a respective door at the landing with an open door status;
- and
- for each elevator car having a door at the landing that is opening at the beginning of the security alert phase, allowing the corresponding door to fully open, subsequently holding the corresponding door open for the remainder of the security alert phase and preventing user control of the corresponding elevator for the remainder of the security alert phase.
3 more elements
A method of securing an elevator access area, the method comprising:
- defining a secure area including an elevator landing providing access to an elevator system including at least one elevator car;
- monitoring the presence or entry of unauthorized individuals in the secure area;
- initiating a security alert phase upon detecting the presence or entry of one or more unauthorized individuals in the secure area;
- monitoring a status of each elevator car in the elevator system during the security alert phase to identify each elevator car having a respective door at the landing with an open door status;
- and
- for each elevator car having a door at the landing that is closing at the beginning of the security alert phase, opening the corresponding door, holding the corresponding door open for the remainder of the security alert phase and preventing user control of the corresponding elevator for the remainder of the security alert phase.
3 more elements
A method of securing an elevator access area, the method comprising:
- defining a secure area including an elevator landing providing access to an elevator system including at least one elevator car;
- monitoring the presence or entry of unauthorized individuals in the secure area;
- initiating a security alert phase upon detecting the presence or entry of one or more unauthorized individuals in the secure area;
- monitoring a status of each elevator car in the elevator system during the security alert phase to identify each elevator car having a respective door at the landing with an open door status;
- and
- for each elevator car that arrives at the landing during the security alert phase, allowing the corresponding door to fully open, subsequently holding the corresponding door open for the remainder of the security alert phase and preventing user control of the corresponding elevator for the remainder of the security alert phase.
3 more elements
An elevator installation comprising:
- an elevator car, the elevator car comprising an elevator car entrance;
- a monitoring device, the monitoring device comprising a card reader or a biometric reader,
- the monitoring device being configured to produce an alarm signal upon detecting a non-authorized individual within an area outside of and around the elevator car entrance;
- and
- an elevator controller, the elevator controller comprising a processor, wherein for each elevator car having a door at the landing that is opening at the beginning of the security alert phase, closing at the beginning of the security alert phase and subsequently reopening, or arriving at the landing during the security alert phase, the elevator controller is configured to determine that a door of the elevator car is at least partly open and prevent use of the elevator car in response to the alarm signal.
2 more elements
One or more computer-readable storage media having encoded thereon instructions that, when executed by a processor, cause the processor to perform a method, the method comprising:
- monitoring an area for unauthorized individuals, the area comprising at least part of an elevator landing;
- initiating an alarm period as a result of detecting at least one unauthorized individual entering the area or in the area;
- for each elevator car having a door at the landing that is opening at the beginning of the security alert phase, closing and subsequently reopening at the beginning of the security alert phase, or arriving at the landing during the security alert phase, determining that an elevator car at the landing has a door that is at least partially open, preventing user operation of the elevator car during the alarm period and preventing closing of the elevator car door during the alarm period.
