Abstract

An elevator system (10) includes a wireless batteryless hall call switch module (22) that transmits a unique wireless code when a person presses a hall call button (32, 34) requesting elevator service. A hall indicator module (24) includes an RF transceiver (64) that receives the wireless code from the switch module (22), activates a display to indicate that a button has been pushed, and transmits the hall call information to the elevator control system (14). When the elevator controller (14) informs the transceiver (64) of car arrival, the hall indicator module (24) causes the display to indicate car arrival.

Claims

1. An elevator call system comprising:

a hall call switch module including a hall call button and a wireless transmitter powered by actuation of the button to transmit a hall call signal; and

a hall lantern module mounted on a hoistway wall, the hall lantern module including a display, an antenna;

an RF transceiver connected to the antenna for receiving the hall call signal, transmitting hall call information to an elevator control system, receiving elevator location information from the elevator control system, and a processor for controlling operation of the display based upon the hall call signal and the elevator location information.

2. The system of claim 1 wherein the display includes up and down button indicators and up and down hall car arrival indicators.

3. The system of claim 1 wherein the hall call switch includes a piezoelectric generator responsive to actuation of the button.

4. An elevator call system comprising:

an elevator control system capable of providing an elevator position signal;

a hall call switch module comprising;

at least on actuatable hall call button; and

a power generator capable of generating power through actuation of a first of the at least one hall call buttons to produce a hall call signal; and

a hall indicator module having a display, wherein the hall indicator module is wirelessly linked to the hall call switch module and to the elevator control system, and wherein the display is controlled as a function of the hall call signal and the elevator position signal.

5. The system of claim 4 wherein the hall indicator module further comprises a second indicator.

6. The system of claim 4, wherein the hall call switch module does not include a display.

7. The system of claim 4 and further comprising:

a wireless RF communication system wirelessly linking the hall call switch module and the hall indicator module.

8. The system of claim 4 and further comprising:

a wireless communication system wirelessly linking the elevator control system and the hall indicator module.

9. The system of claim 4, wherein the indicator of the hall indicator module is a lamp.

10. An elevator call system comprising:

an elevator entryway;

an indicator module capable of providing elevator status information, wherein the indicator module is positioned in an area of the elevator entryway; and

a wireless and batteryless call switch module located remote from the indicator module, the call switch module comprising;

a hall call button;

a wireless transmitter for transmitting a hall call signal to the indicator module; and

a power generator responsive to actuation of the hall call button.

11. The system of claim 10, wherein the power generator includes a piezoelectric element for powering the wireless transmitter through actuation of the hall call button.

12. The system of claim 10, wherein the wireless communication system is an RF transceiver system.

13. The system of claim 10 and further comprising:

an elevator control system capable of providing an elevator position signal, wherein the indicator module is wirelessly linked to both the call switch module and the elevator control system, and wherein the elevator status information is a function of the hall call signal and the elevator position signal.

14. The system of claim 10, wherein the elevator status information is provided as a binary visual indication.

15. The system of claim 10, wherein the call switch module does not include a display.
