Abstract

A method of operating an elevator system includes the steps of specifying and storing at least one profile describing at least one elevator operational characteristic, including an elevator security function specifying a landing or landings for which hall calls are not to be responded to and a landing or landings for which car calls are not to be responded to. The profile has a start time, an end time, and a day or days of the week specified therefor during which time the profile is to be activated. A next step repetitively determines a current time and a current day of the week and compares the current time and current day of the week to the specified start time, end time, and day or days of the week associated with the at least one stored profile. Responsive to an equality condition, the method includes a further step of transmitting information to a controller of at least one elevator car within a group of elevator cars. The transmitted information causes the at least one elevator car to begin operating in accordance with the specified profile, or to stop operating in accordance with the specified profile.

Claims

1. A method of operating an elevator system, comprising the steps of:

specifying a profile describing at least one elevator operational characteristic, the profile having a start time, an end time, and at least one day of the week specified therefor;

storing the profile;

repetitively determining a current time and a current day of the week;

comparing the current time to the start time and to the end time associated with the stored profile and also comparing the current day of the week to the specified at least one day of the week; and

responsive to the comparison indicating that the current time equals either the start time or the end time, and that the current day of the week equals the at least one specified day of the week, transmitting information to at least one elevator car within a group of elevator cars for then causing at least one elevator car to begin operating in accordance with the specified profile or to stop operating in accordance with the specified profile.

2. A method as set forth in claim 1 wherein the step of specifying includes a step of specifying an elevator security function.

3. A method as set forth in claim 2 wherein the step of specifying an elevator security function specifies a landing or landings for which hall calls are not to be responded to.

4. A method as set forth in claim 2 wherein the step of specifying an elevator security function specifies a landing or landings for which car calls are not to be responded to.

5. A method as set forth in claim 1 wherein the step of specifying specifies elevator group commands, elevator car commands, elevator group parameters, and elevator car parameters.

6. A method as set forth in claim 1 wherein the step of transmitting transmits the information to a ring communication bus, the ring communication bus having at least one elevator car controller coupled thereto.

7. An elevator system, comprising:

means for generating an indication of a current time, including a current day of the week; and

control means, said control means including,

means for receiving and storing at least one profile describing at least one elevator operational characteristic, the profile having a start time, an end time, and at least one day of the week specified therefor;

means, having an input coupled to an output of said time generating means, for comparing the current time to the start time and to the end time associated with the stored profile and for comparing the current day of the week to the at least one day of the week associated with the stored profile; and

means, responsive to the comparison indicating that the current time equals either the start time or the end time, and that the current day of the week equals the at least one specified day of the week, for transmitting information to at least one elevator car within a group of elevator cars for causing the at least one elevator car to begin operating in accordance with the specified profile or to stop operating in accordance with the specified profile.

8. An elevator system as set forth in claim 7 wherein the receiving and storing means includes means for receiving and storing profile information specifying an elevator security function.

9. An elevator system as set forth in claim 8 wherein the profile information specifies a landing or landings for which hall calls are not to be responded to.

10. An elevator system as set forth in claim 8 wherein the profile information specifies a landing or landings for which car calls are not to be responded to.

11. An elevator system as set forth in claim 7 wherein the receiving and storing means includes means for receiving and storing profile information for specifying elevator group commands, elevator car commands, elevator group parameters, and elevator car parameters.

12. An elevator system as set forth in claim 7 wherein the means for transmitting is coupled to a communication bus for transmitting the information thereto, and wherein the communication bus has at least one elevator car control means coupled thereto for receiving the information and for operating the elevator car in accordance therewith.

13. A method of operating an elevator system, comprising the steps of:

specifying at least one profile describing at least one elevator operational characteristic, including an elevator security function specifying a landing or landings for which hall calls are not to be responded to and a landing or landings for which car calls are not to be responded to, the profile further having a start time, an end time, and a day or days of the week specified therefor during which time the profile is to be activated;

storing the at least one profile;

repetitively determining a current time and a current day of the week;

comparing the current time and current day of the week to the specified start time, end time, and day or days of the week associated with the at least one stored profile; and

responsive to the comparison indicating that the current time equals either the start time or the end time, and to the comparison indicating that the current day of the week equals one of the specified days of the week, transmitting information over a communication bus to a control means of at least one elevator car within a group of elevator cars for causing the at least one elevator car to begin operating in accordance with the specified profile or to stop operating in accordance with the specified profile.

14. A method as set forth in claim 13 wherein the step of specifying specifies elevator group commands, elevator car commands, elevator group parameters, and elevator car parameters.

15. A method as set forth in claim 13 wherein the step of transmitting transmits the information to a ring communication bus, the ring communication bus having at least one of the elevator car control means coupled thereto.

16. A method as set forth in claim 13 wherein, responsive to a determination that an elevator car control means is not executing a specified one of the profiles, includes a step of transmitting information over the communication bus to the control means of at least one elevator car within the group of elevator cars for causing at least one elevator car to begin operating in accordance with a default profile.

17. A method as set forth in claim 13 wherein the elevator security function specifies, on a front car door and on a rear car door basis, a landing or landings for which hall calls are not to be responded to and a landing or landings for which car calls are not to be responded to.
