Abstract

In an elevator installation system of at least one elevator installation with one or more elevators and a service center, which is functionally connected therewith, but provided spatially separate therefrom, the control device of the elevator installation is likewise disposed in the service center. The control device stands in connection with the elevator installation by way of a data transmission device. Data for the control of the elevator installation are prepared in situ and transmitted either to the service center or to the control device, preferably by way of a public telephone network. After processing of the information in the service center, a return transmission of the ascertained control instructions and a corresponding actuation of the setting members and actuators for the operation of the elevators take place.

Claims

1. An elevator installation system, comprising:

at least one elevator installation which includes at least one elevator;

control means for controlling operation of the elevator installation;

a service center which is spatially separate from the elevator installation for monitoring operation of the installation; and

data transmission means for exchanging data relevant to an elevator between the elevator installation and the service center, the data transmission means including a first transmission device arranged in the service center, a second transmission device arranged at the elevator installation, and a data path arranged to connect the first transmission device with the second transmission device, the control means being arranged in the service center so that there is no elevator control at the elevator installation, and all data relevant to control technique are transmissible reciprocally between the control means and the elevator installation by the data transmission means.

2. An elevator installation system according to claim 1, wherein the control means is associated with several elevator installations.

3. An elevator installation system according to claim 1, wherein the data path is formed by optical conductors.

4. An elevator installation system according to claim 1, wherein the data path is formed by metallic conductors.

5. An elevator installation system according to claim 1, wherein the data path is a telephone network.

6. A method for controlling operation of an elevator installation system including at least one elevator installation which has at least one elevator, control means for controlling operation of the elevator installation, a service center which is spatially separate from the elevator installation for monitoring operation of the installation, the control means being located at the service center so that no elevator controls are at the elevator installation, and data transmission means for exchanging data relevant to an elevator between the elevator installation and the service center, the data transmission means including a first transmission device arranged in the service center, and a second transmission device arranged at the elevator installation, and a data path arranged to connect the first transmission device to the second transmission device, the method comprising the steps of:

transmitting data relevant to control of the elevators, via the data transmission means, to the control means which is spatially separate from the elevators;

processing the transmitted data in the control means into control commands for the elevators; and

transmitting the control commands from the service center by way of the data transmission means to the elevators for actuating setting members.

7. A method for controlling the operation of an elevator installation system according to claim 6, including operating several elevators with one control means.

8. A method for controlling, the operation of an elevator installation system according to claim 6, wherein the transmitting step includes transmitting data relevant to control by wireless media.

9. A method for controlling the operation of an elevator installation system according to claim 6, wherein the transmitting step includes transmitting data relevant to control by cable-bound media.
