Abstract

An elevator device includes an operation control unit ( 18 ), a storage unit ( 22 ), a transmission unit ( 23 ), a determination unit ( 25 ), and a recovery unit ( 26 ). When an inspection operation is interrupted by the operation control unit ( 18 ), the transmission unit ( 23 ) transmits inspection data stored in the storage unit ( 22 ) to a plurality of specific devices ( 20 ). The determination unit ( 25 ) determines whether or not recovery conditions are satisfied on the basis of a plurality of responses from the devices ( 20 ) to which the transmission unit ( 23 ) transmits the inspection data. For example, the recovery unit ( 26 ) restores a normal operation when the determination unit ( 25 ) determines that the recovery conditions are satisfied.

First claim

The invention claimed is:

1. An elevator device, comprising:
circuitry to
perform an inspection operation that collects and analyzes inspection data after detecting an occurrence of an earthquake and after performing an earthquake emergency operation;
interrupt the inspection operation before the inspection operation is completed, when an abnormality is detected by analyzing the collected inspection data;
transmit, when the inspection operation is interrupted, the inspection data collected during the inspection operation to a plurality of specific devices;
determine whether or not recovery conditions are satisfied based on a plurality of responses from the specific devices with respect to the transmitted inspection data, after the inspection operation has been interrupted; and
restore a normal operation or cause the inspection operation to be restarted, when the recovery conditions are determined to be satisfied, after the inspection operation has been interrupted.

2. The elevator device according to claim 1 , wherein the circuitry is further configured to transmit the inspection data collected during the inspection operation to a transmission destination registered in advance in order to make the inspection data accessible to the specific devices or transmit the inspection data directly to the specific devices.

3. The elevator device according to claim 1 , wherein the specific devices are mobile terminals.

4. The elevator device according to claim 3 , wherein the circuitry is further configured to transmit the collected inspection data to the specific devices located in an area separated from an installation site of the elevator device by 300 km or more.

5. An elevator device, comprising:
circuitry to
start an inspection operation that collects and analyzes inspection data, based on state data, after detecting an occurrence of an earthquake and after performing an earthquake emergency operation;
transmit, when determining that the inspection operation is not started after detecting the occurrence of the earthquake, the state data, which is collected after the occurrence of the earthquake, to a plurality of specific devices;
determine whether or not start conditions are satisfied based on a plurality of responses from the specific devices with respect to the transmitted state data, when the inspection operation has not been started; and
cause the inspection operation to be started when the start conditions are determined to be satisfied.

6. The elevator device according to claim 5 , wherein the circuitry is further configured to transmit the state data collected after the occurrence of the earthquake to a transmission destination registered in advance in order to make the state data accessible to the specific devices or transfer the state data directly to the specific devices.

7. The elevator device according to claim 5 , wherein the devices are mobile terminals.

8. The elevator device according to claim 7 , wherein the circuitry is further configured to transmit the collected inspection data to the specific devices located in an area separated from an installation site of the elevator device by 300 km or more.

9. An elevator recovery method, comprising:
performing an inspection operation that collects and analyzes inspection data after an occurrence of an earthquake and after performing an earthquake emergency operation;
interrupting the inspection operation before the inspection operation is completed, when an abnormality is detected by analyzing the collected inspection data;
transmitting, when the inspection operation is interrupted, the inspection data collected during the inspection operation to a plurality of specific devices;
determining whether or not recovery conditions are satisfied based on a plurality of responses from the specific devices with respect to the transmitted inspection data, after the inspection operation has been interrupted; and
restoring a normal operation or causing the inspection operation to be restarted, when the recovery conditions are determined to be satisfied, after the inspection operation has been interrupted.

10. The elevator recovery method according to claim 9 , wherein the transmitting step comprises transmitting the inspection data collected during the inspection operation to a transmission destination registered in advance in order to make the inspection data accessible to the specific devices or transfer the inspection data directly to the specific devices.

11. The elevator recovery method according to claim 9 , wherein the devices are mobile terminals.

12. The elevator recovery method according to claim 11 , wherein the transmitting step comprises transmitting the collected inspection data to the specific devices located in an area separated from an installation site of the elevator device by 300 km or more.

13. An elevator recovery method, comprising:
starting an inspection operation that collects and analyzes inspection data based on analyzing state data, after detecting an occurrence of an earthquake and after performing an earthquake emergency operation;
transmitting, when determining that the inspection operation is not started after detecting the occurrence of the earthquake, the state data, which is collected after the occurrence of the earthquake, to a plurality of specific devices;
determining whether or not start conditions are satisfied based on a plurality of responses from the specific devices with respect to the transmitted state data, when the inspection operation has not been started; and
starting the inspection operation when the start conditions are determined to be satisfied.

14. The elevator recovery method according to claim 13 , wherein the transmitting step comprises transmitting the state data collected after the occurrence of the earthquake to a transmission destination registered in advance in order to make the state data accessible to the specific devices or to transfer the state data directly to specific devices.

15. The elevator recovery method according to claim 13 , wherein the devices are mobile terminals.

16. The elevator recovery method according to claim 15 , wherein the transmitting step comprises transmitting the collected inspection data to the specific devices located in an area separated from an installation site of the elevator device by 300 km or more.
