Abstract

A method for the exchange of data between one unit of an elevator system and a monitoring unit of a service center locationally remote from the elevator system, wherein, via a first communication network, the one unit is connected with a communication unit arranged on, or in, an elevator car that travels vertically in an elevator hoistway, and wherein the data that are transmitted by the one unit are transmitted to the communication unit and stored there. A mobile-communication end-device brought into the elevator car by an elevator passenger is connected, via a second wireless communication network, with the communication unit and the stored data are transmitted by the communication unit to the end-device, and stored in the latter. When the elevator car is exited by the elevator passenger with the end-device, the stored data are transmitted from the end-device via a public mobile-communication network to the monitoring unit.

Claims

1. A method for the exchange of data between at least one unit of an elevator system and a monitoring unit of a service center that is locationally remote from the elevator system, wherein the elevator system includes an elevator car that runs in an elevator hoistway, a first wireless communication network that connects the at-least one unit with a first communication unit arranged on, or in, the elevator car, and wherein data transmitted from the at-least one unit are stored in the first communication unit, comprising the steps of:

a mobile-communication end-device, which is brought into the elevator car by an elevator passenger, is connected, via a second wireless communication network, with the first communication unit;

the data that are transmitted by the at-least one unit to the first communication unit, and stored there, are transmitted by the first communication unit to the mobile-communication end-device and stored therein; and

after the elevator car is exited by the elevator passenger with the mobile-communication end-device, the stored data are transmitted by the mobile-communication end-device, via a public mobile-communication network, to the monitoring unit that is locationally remote from the elevator system, wherein the end-device is not in communication with the public mobile-communication network when the end-device is in the elevator car.

2. The method according to claim 1 wherein, depending on at least one rule, the data are transmitted by the first communication unit to the mobile-communication end-device and stored there.

3. The method according to claim 1 wherein the at least one rule is based on at least one of a previously defined data volume, a priority of the data, a safety-requirement criterion, a time delay, a signal strength and a transmission time.

4. The method according to claim 2 wherein, depending on at least one further rule, the stored data are transmitted by the mobile-communication end-device via the public mobile-communication network to the monitoring unit.

5. The method according to claim 4 wherein the at least one further rule is based on at least one of a previously defined data volume, a priority of the data, a safety-requirement criterion, a time delay, a signal strength and a transmission time.

6. The method according to claim 1 wherein the first communication network is a wireless communication network or a wired communication network.

7. The method according to claim 1 wherein the mobile-communication end-device is one of a computer, a tablet computer, and an intelligent mobile-communication end-device.

8. The method according to claim 7 wherein the mobile-communication end-device includes at least one program for storing, managing, and transmitting the data.

9. The method according to claim 1 wherein the at least one unit is a sensor unit or an elevator control unit.

10. The method according to claim 9 wherein the data are transmitted by the sensor unit when the elevator car with the first communication unit is caused to travel past the sensor unit or is in proximity to the sensor unit.

11. The method according to claim 9 wherein a communication range of the sensor unit matches a cross section of the elevator hoistway.

12. The method according to claim 9 wherein the sensor unit is one of an acceleration sensor, a temperature sensor, an air-pressure sensor, a current sensor, a voltage sensor, a light sensor, an air-humidity sensor, a door-contact unit, a safety unit, a weight sensor, a velocity sensor and a position sensor.

13. The method according to claim 1 wherein the first communication unit includes a data storage unit connected to a data communication module.
