Embodiment form 1.

1 is a block diagram showing an outline of a remote monitoring system to which the elevator remote inspection device according to Embodiment 1 is applied.

In the remote monitoring system shown in FIG. 1, the elevator 1 is installed in a building not shown. The elevator 1 is provided with a control panel 2. The control panel 2 is installed in the same building as the elevator 1. The control panel 2 is installed to control the overall operation of the elevator 1.

The monitoring device 3 is installed in the same building as the elevator 1. The monitoring device 3 is electrically connected to the control panel 2. The monitoring device 3 is installed to collect operation information of the elevator 1 from the control panel 2. The monitoring device 3 is installed to store the driving information. The monitoring device 3 is installed so that a power outage notification can be sent when a power outage occurs in a building in which the elevator 1 is installed. The monitoring device 3 is installed so that a restoration notification can be sent when the power outage is restored.

The communication base station 4 is installed in a location different from the building where the elevator 1 is installed. The communication base station 4 mediates communication.

The remote inspection device 5 is installed in a building different from the building in which the elevator 1 is installed. For example, the remote inspection device 5 is installed in the building of a maintenance company for the elevator 1. The remote inspection device 5 can communicate with the monitoring device 3 by using an existing communication system such as a priority telephone line or wireless communication line. At this time, the remote inspection device 5 can communicate with the monitoring device 3 via the communication base station 4.

The remote inspection device 5 is installed so that disaster information can be acquired through communication from an external organization. Specifically, the remote inspection device 5 can acquire disaster information about disasters such as heavy rain, typhoons, or earthquakes in a specific area from an external organization. The remote inspection device 5 can acquire information about a power outage that occurred in a specific area from an external organization as disaster information.

The remote inspection device 5 includes a remote inspection unit 6, an information processing unit 7, a disaster determination unit 8, a power outage determination unit 9, and an inspection postponement unit 10.

The remote inspection unit 6 performs a remote inspection operation to acquire the operation information of the elevator 1 accumulated from the monitoring device 3 at regular intervals at set timings. Specifically, for example, the remote inspection unit 6 performs a remote inspection operation at a set date and time every month. In the remote inspection operation, the remote inspection unit 6 transmits a command for performing the remote inspection operation to the monitoring device 3. After that, when the remote inspection unit 6 receives a response signal from the monitoring device 3, it performs an operation to acquire driving information from the monitoring device 3.

When the remote inspection unit 6 does not receive a response signal from the monitoring device 3 after transmitting the command to start the remote inspection operation, the remote inspection unit 6 sets the set number of retries as the upper limit and sends the remote inspection operation to the monitoring device 3. Send a command to perform a remote inspection operation. Specifically, the remote inspection unit 6 sets the number of retries as the upper limit of 20 and transmits a command to start the remote inspection operation to the monitoring device 3.

When the remote inspection unit 6 receives an instruction to postpone the remote inspection operation to another date and time at the set date and time, it postpones the date and time for performing the remote inspection operation by a specified period. Specifically, for example, when the remote inspection unit 6 receives the command, it postpones the date and time of performing the remote inspection operation by 6 hours.

The information processing unit 7 performs failure diagnosis of the elevator 1 using the operation information acquired by the remote inspection unit 6. The information processing unit 7 creates report information for the owner of the elevator 1 using the operation information acquired by the remote inspection unit 6.

The disaster determination unit 8 acquires disaster information from an external organization. When the date and time at which the remote inspection unit 6 performs the remote inspection arrives, the disaster determination unit 8 determines that at least one of the area where the elevator 1 is installed and the area where the communication base station 4 is installed has a disaster based on the disaster information. Determine whether is occurring. For example, when a heavy rain warning is issued for an area where the elevator 1 is installed, the disaster determination unit 8 determines that a disaster has occurred in the area based on the disaster information of the heavy rain warning. .

The power outage determination unit 9 receives a power outage notification sent by the monitoring device 3. The power failure determination unit 9 receives a recovery notification sent by the monitoring device 3. The power failure determination unit 9 determines that the elevator 1 is in a power failure state when no restoration notification is received after receiving the power failure notification.

At the time when the remote inspection unit 6 performs the remote inspection, the disaster determination unit 8 determines that a disaster has occurred in at least one of the area where the elevator 1 is installed and the area where the communication base station 4 is installed. In this case, the inspection postponement unit 10 transmits a command to the remote inspection unit 6 to postpone the remote inspection operation to another date and time.

When the power failure determination unit 9 determines that the elevator 1 is in a power outage state at the time when the remote inspection unit 6 performs the remote inspection, the inspection postponement unit 10 determines that the remote inspection unit 6 A command is sent to postpone the remote inspection operation to another date.

Next, the processing performed by the remote inspection device 5 will be explained using FIG. 2.

FIG. 2 is a flowchart for explaining the outline of processing of the elevator remote inspection device in Embodiment 1.

As shown in FIG. 2, in step S001, the remote inspection device 5 determines whether it is the date and time to perform the remote inspection operation.

If it is determined in step S001 that the date and time for performing the remote inspection operation is not, the remote inspection device 5 repeats the operation of step S001.

When it is determined in step S001 that the remote inspection operation is to be performed, the remote inspection device 5 performs the operation in step S002. In step S002, the remote inspection device 5 determines whether a disaster has occurred in at least one of the area where the elevator 1 is installed and the area where the communication base station 4 is installed.

If it is determined in step S002 that a disaster has not occurred in any area, the remote inspection device 5 performs the operation of step S003. In step S003, the remote inspection device 5 determines whether the elevator 1 is in a power outage state.

When it is determined in step S003 that the elevator 1 is not in a power outage state, the remote inspection device 5 performs the operation of step S004. In step S004, the remote inspection device 5 performs a remote inspection operation.

After that, the remote inspection device 5 ends the processing.

If it is determined in step S002 that a disaster has occurred in at least one of the area where the elevator 1 is installed and the area where the communication base station 4 is installed, or if it is determined in step S003 that the elevator 1 is in a power outage, remote inspection The device 5 performs the operation in step S005. In step S005, the remote inspection device 5 postpones the remote inspection operation for a specified period of time. Specifically, in step S005, the remote inspection device 5 waits for a specified period of time. After that, the remote inspection device 5 performs operations from step S002 onward.

According to Embodiment 1 described above, the remote inspection device 5 is provided with a remote inspection unit 6, a disaster determination unit 8, and an inspection postponement unit 10. The inspection postponement unit 10 causes the remote inspection unit 6 to postpone the remote inspection operation to another date and time by transmitting a command. For this reason, when communication with the monitoring device 3 is not possible due to the occurrence of a disaster, the remote inspection device 5 can avoid performing a remote inspection operation regarding the monitoring device 3. Specifically, the remote inspection device 5 can suppress sending a command to perform a remote inspection operation to the monitoring device 3 by the number of retries. As a result, it is possible to suppress the load on the communication line in the event of a disaster.

Additionally, the inspection postponement unit 10 may transmit a confirmation command to the remote inspection unit 6 before transmitting a command to postpone the remote inspection operation to another date and time. When receiving a confirmation command, the remote inspection unit 6 may perform a confirmation operation of transmitting a command for transmitting operation information to the monitoring device 3 a specified number of times less than the number of retries. The number of retries is the upper limit number of times to transmit a command to the monitoring device 3 when a disaster is not recognized. On the other hand, the number of times specified in this regulation is the number of times a command is transmitted to the monitoring device 3 when a disaster is recognized. Specifically, the remote inspection unit 6 may perform a confirmation operation of transmitting the command only twice. When the remote inspection unit 6 cannot acquire operation information for the confirmation operation, the inspection postponement unit 10 may transmit an instruction to postpone the remote inspection operation to another date and time. For this reason, in the case where disaster information in the target area is not updated to the restored state despite recovery from a disaster, the remote inspection device 5 can acquire driving information from the monitoring device 3. Additionally, the number of times specified in this regulation is less than the number of retries. For this reason, even when communication with the monitoring device 3 is not possible, it is possible to suppress the burden on the communication line in the event of a disaster.

Moreover, when the remote inspection device 5 determines that the elevator 1 is out of power when the date and time for performing the remote inspection operation has arrived, it postpones the date and time for performing the remote inspection operation to another date and time. For this reason, after a disaster occurs, when the elevator 1 is not recovering from a power outage, the remote inspection device 5 transmits a command to perform a remote inspection operation to the monitoring device 3 equal to the number of retries. It can be suppressed. As a result, it is possible to suppress the load on the communication line.

The remote inspection device 5 may perform the remote inspection operation not only when the set date and time has been reached, but also when the set conditions have been satisfied. In this case, the remote inspection device 5 may postpone the timing of performing the remote inspection operation by a specified period. In addition, the remote inspection device 5 may postpone the timing of performing the remote inspection operation to another timing, such as performing the remote inspection operation when the specified conditions are satisfied.

Additionally, the disaster determination unit 8 may detect that the state in which a disaster occurred has been resolved based on an operation from the operator of the maintenance company.
