Elevator installation modernization using an existing interface
First Claim
1. An elevator installation modernization method comprising:
- placing a destination call control at an elevator installation, the destination call control being configured to generate start floor signals and destination floor signals based at least in part on at least one of a destination call signal or an identification code; and
connecting the destination call control with an existing elevator control using an existing serial maintenance interface of the existing elevator control, such that the destination call control is configured to provide the start floor signals and the destination floor signals to the existing elevator control through the existing serial maintenance interface by implementing a communications protocol compatible with the existing serial maintenance interface to provide the start floor signals and the destination floor signals to the existing elevator control.

Abstract
An elevator installation for serving at least one floor in at least one building can be modernized, the elevator installation comprising at least one elevator with at least one elevator car and at least one elevator control. At least one destination call terminal for input of at least one destination call and/or for recognition of at least one identification code is installed on at least one input floor. At least one destination call control is installed. The destination call terminal is, for communication of the destination call signal, connected with the destination call control. The destination call control can be connected to the elevator control through a serial interface of the elevator control.

14. An elevator modernization device, comprising:
-
a processor;
a serial interface configured to connect the elevator modernization device with an existing maintenance interface of at least one existing elevator control of an elevator installation; anda memory storing instructions which, when executed by the processor, cause the processor to generate start floor signals and destination floor signals based at least in part on a destination call signal or an identification code, and which further cause the processor to communicate the start floor signals and the destination floor signals to the at least one existing elevator control through the existing serial maintenance interface, wherein the elevator modernization device is configured to use a communications protocol that is compatible with the existing serial maintenance interface to provide the start floor signals and the destination floor signals to the at least one existing elevator control. - View Dependent Claims (15, 16)

17. An elevator installation comprising:
-
a destination call terminal; a destination call control coupled to the destination call terminal and implementing a communications protocol compatible with a serial maintenance interface and receiving start floor signals and destination floor signals from the destination call terminal; an elevator control comprising the serial maintenance interface and coupled to the destination call control through the serial maintenance interface, and receiving the start floor signals and the destination floor signals from the destination call control implementing the communications protocol via the serial maintenance interface.

18. An elevator installation modernization method comprising:
-
generating, by a destination call control, start floor signals and destination floor signals based at least in part on at least one of a destination call signal or an identification code; connecting, using an existing serial maintenance interface of the existing elevator control, the destination call control with an existing elevator control; implementing, by the destination call control, a communications protocol compatible with the existing serial maintenance interface to provide the start floor signals and the destination floor signals to the existing elevator control; and transmitting, by the destination call control, the start floor signals and the destination floor signals to the existing elevator control using the communications protocol and the existing serial maintenance interface.
