Methods and tools for servicing an elevator system
First Claim
1. A method of servicing an elevator system which includes a plurality of elevator cars mounted in a building, and a supervisory system processor which makes assignments to the elevator cars responsive to system conditions and a predetermined strategy, comprising the steps of:
- providing a visual display which displays the assignments made to the cars by the system processor,providing means for selectively entering calls for elevator service,inhibiting the elevator cars from moving,entering a call for elevator service,and observing the assignments made to the cars by the system processor.

Abstract
Apparatus and methods for servicing an elevator system having a plurality of elevator cars under the supervision of a supervisory system processor. The system processor makes assignments to the cars according to a predetermined strategy. The servicing tool is connectable to the elevator system such that the positions of the cars in the building, the assignments to the cars by the system processor, and the status of the elevator cars, are displayed on a panel position and motion indicator or display. The servicing tool also includes pushbuttons for entering car and hall calls, and a mode select switch. The mode select switch includes an operating mode in which the system processor is maintained operational, and the controls of the cars are maintained operational, except the cars are inhibited from moving. The servicing method includes inhibiting the cars from moving while predetermined calls are entered into the system. The assignments to the cars, the change in assignments, and the change in the status of the cars as each call is entered, are noted by viewing the display. The display image, after each call is entered, may be compared with the correct image or response of the system processor and cars, to quickly check the system processor and car controllers to determine if they are operating properly.

9. A method of servicing an elevator system which includes a plurality of elevator cars mounted in a building to serve the floors therein, a supervisory system processor which makes assignments to the cars responsive to system conditions and a predetermined strategy, call entering means for entering calls for elevator service, and memory means for storing calls for elevator service until they are answered, comprising the steps of:
-
providing a visual display which displays the positions of the elevator cars in the building, and the locations of calls for elevator service in the building, providing auxiliary call entering means separate from the call entering means associated with the elevator system, providing auxiliary memory means separate from the memory means associated with the elevator system, and OR'"'"'ing the calls stored in the two separate memory means to provide a composite signal which includes calls from both memory means.

10. A method of servicing an elevator system which includes a plurality of elevator cars mounted in a building, and a supervisory system processor which makes assignments to the elevator cars responsive to system conditions and a predetermined strategy, comprising the steps of:
-
providing a visual display which displays assignments made to the cars by the system processor, the locations of the cars in the building, the locations of calls for elevator service and signals which indicate the status of each of the elevator cars, providing means adjacent to the visual display for selectively entering calls for elevator service, inhibiting the elevator cars from moving, entering a call for elevator service, and observing the assignments made to the cars by system processor, and the status signals relative to the cars. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)

18. A servicing tool for servicing an elevator system having a plurality of cars mounted in a building to serve the floors therein, conventional call means for entering calls for elevator service, and a supervisory system processor which makes assignments to the elevator cars responsive to system conditions and a predetermined strategy, comprising:
-
a visual display for displaying assignments to the cars by the system processor, and the positions of the elevator cars in the building, call entering means for selectively entering calls for elevator service remote from the conventional call means, and inhibit means for inhibiting the elevator cars from moving, wherein assignments to the cars by the supervisory system processor in response to calls entered on said call entering means may be observed on the visual display. - View Dependent Claims (19, 20)
