Abstract

A passenger transportation system, in particular an elevator system or an escalator, includes an emergency-call system that has a plurality of telephones, a monitoring system that has a plurality of monitoring units for monitoring the functioning of the passenger transportation system, and a central control unit. The monitoring units are suitable for exchanging data between themselves and with the central control unit, the monitoring units, the central control unit, and the telephones being connected to each other via one and the same data conductor.

Claims

1. A passenger transportation system, in particular an elevator system or escalator, with an emergency-call system that includes a plurality of telephones, and with a monitoring system that includes a plurality of monitoring units for monitoring the functioning of the passenger transportation system and a central control unit, comprising:

the monitoring units being suitable for exchanging data between themselves and with the central control unit; and

a single data conductor being connecting the monitoring units, the central control unit and the telephones to each other.

2. The passenger transportation system according to claim 1 wherein said the data conductor is a telephone line that is provided for an emergency-call telephone system of an elevator system or for a telephone system of a building.

3. The passenger transportation system according to claim 1 wherein at least one of the monitoring units and the telephones are each connected to the data conductor by a subscriber line.

4. The passenger transportation system according to claim 3 wherein the monitoring units are connected to said subscriber line via an interface such as a network adapter or a modem.

5. The passenger transportation system according to claim 1 wherein the monitoring units monitor at least one of rotational speed of a motor drive, a speed, and a direction of travel of the passenger transportation system.

6. The passenger transportation system according to claim 1 wherein the monitoring units are suitable for mutual monitoring.

7. The passenger transportation system according to claim 1 wherein the control unit contains at least one processor, one data transmission unit, and at least one interface.

8. The passenger transportation system according to claim 7 where in said at least one interface is one of a USB interface, a PCI interface, an Ethernet interface, an XDSL interface and a serial interface.

9. The passenger transportation system according to claim 7 wherein said at least one interface is connected to at least one peripheral device such as a printer or an elevator controller.

10. The passenger transportation system according to claim 1 wherein said data conductor is an Internet line that is suitable for Internet telephony.

11. An elevator installation with an emergency-call system comprising:

a plurality of telephones;

a monitoring system including a plurality of monitoring units for monitoring the functioning of the elevator installation;

a central control unit; and

a single data conductor being connecting said monitoring units, said central control unit and said telephones to each other, said monitoring units being suitable for exchanging data between themselves and said central control unit.
