Abstract

An adaptive elevator security system has a security module (52) which uses data stored in a configuration data element (64) to update a security state data element (62). The security module (52) provides data from a raw car/hall call data element (56) to a filtered car/hall call data element (58) according to data stored in the security state data element (62).

Claims

1. A method of providing secure service to an elevator system in a building, comprising:

providing a plurality of configuration signals indicative of a table of entries, each entry including a field identifying a particular security peripheral device which may be actuated to affect access to use of the elevator system, a field identifying a floor of the building, the access to which is to be affected by actuation of the related peripheral device, a field identifying an electro car involved in the affected access of said entry and a field indicating whether said entry is effective or not to deny access in response to car calls, up hall calls or down hall calls, receptively;

providing, in response to actuation of a security peripheral device, a security input signal indicative of such security peripheral device having been actuated;

providing, in response to said configuration signals and said security input signal, a plurality of security state signals separately indicative of any floors to which access is to be denied from any specific elevator car, any floors from which access si to be denied to any specific elevator car traveling in the up direction, and any floors from which access is to be denied to any specific elevator car reveling in the down direction;

providing, in response to actuation of hall call buttons and car calls buttons, corresponding raw hall call signals and raw car call signals;

`and providing to said elevator system, filtered hall call signals and filtered car call signal each corresponding to a related one of said raw hall call signals and said raw car call signals relating to service not involving access which is indicated by said security state signals as access to be denied.

2. A method according to claim 1, wherein each entry includes a field indicating whether said security state signals should indicate access is to be denied in response to said corresponding particular security peripheral device being actuated ON or actuated OFF.

3. A method according to claim 1 wherein each entry includes a field indicating a default operation with respect to said entry to become effective in the event that is becomes impossible to provide said security input signal in response to actuation of the corresponding device.

4. A method according to claim 1 wherein each entry includes a field indicating a corresponding message to be displayed in relation to said entry.

5. A method according to claim 1 wherein each entry includes a field indicating interaction with another security peripheral device and the actuation condition thereof which affects the access related to said entry.
