In addition, the same code|symbol is attached|subjected to the part which is the same or corresponds in each figure. Redundant description of the relevant part will be simplified or omitted as appropriate.

Embodiment 1.
FIG. 1 is a diagram showing an overview of a remote monitoring system to which a remote monitoring device for elevators according to Embodiment 1 is applied.

In FIG. 1, multiple elevators 1 are installed in multiple buildings (not shown). Each of the plurality of elevators 1 is an elevator. Each of the elevators 1 has an individual monitoring device 2 . The individual monitoring device 2 is provided so as to be able to grasp the operating state of the corresponding elevator 1 .

The information center 3 is located in a building separate from the multiple buildings. For example, the information center 3 is provided in an elevator maintenance company.

The polling device 4 is provided inside the information center 3. The polling device 4 comprises a receiving section 5 , a polling section 6 and a state storage section 7 .

The receiving unit 5 is provided so as to be able to communicate with each of the plurality of elevators 1. A polling unit 6 is provided so as to be able to communicate with each of the plurality of elevators 1 . The state storage unit 7 stores state information indicating whether each of the plurality of elevators 1 is in a stopped state, a non-stopped state, or an unconfirmed state. The state storage unit 7 stores state information indicating that all the elevators 1 are in an unconfirmed state when an earthquake has not occurred.

The remote monitoring device 8 is provided inside the information center 3. A remote monitoring device 8 is provided to communicate with the polling device 4 . For example, the remote monitoring device 8 is provided so as to be able to acquire earthquake information from K-NET, which is an external earthquake information distribution service, via a communication line.

The first storage device 9 is provided inside the information center 3 . A first storage device 9 is provided for communication with the remote monitoring device 8 . The first storage device 9 stores elevator information including information on the location of the building where each of the plurality of elevators 1 is installed.

The second storage device 10 is provided inside the information center 3 . A second storage device 10 is provided for communication with the remote monitoring device 8 . The second storage device 10 stores past record information in which whether each of the plurality of elevators 1 has been brought into a stopped state or a non-stopped state due to an earthquake is associated with the earthquake information.

If the scale of shaking of a building when an earthquake occurs is larger than the prescribed scale, the elevator 1 installed in the building will be stopped after performing controlled operation. In this case, the individual monitoring device 2 in the elevator 1 transmits information to the receiver 5 of the polling device 4 that the elevator 1 is in a stopped state. When receiving the information indicating that the elevator 1 is in the stopped state, the receiving unit 5 causes the state storage unit 7 to store the state information indicating that the elevator 1 is in the stopped state.

If the scale of the shaking of a building when an earthquake occurs is less than the prescribed scale, the elevator 1 installed in the building will return to normal operation after conducting controlled operation or will continue normal operation. In this case, the elevator 1 remains in a non-stop state. When the elevator 1 remains in the non-stop state, the individual monitoring device 2 of the elevator 1 does not transmit information by itself.

When an earthquake occurs, the administrator of a certain elevator 1 sends information to the effect that the elevator 1 has stopped due to the earthquake or information to the effect that the elevator 1 remains in a non-stop state from a terminal (not shown) to the reception unit of the polling device 4. 5 may be sent. When receiving information indicating that the elevator 1 is in a stopped state or information indicating that the elevator 1 remains in a non-stop state, the receiving unit 5 determines that the elevator is in a stopped state or remains in a non-stop state. The state information is stored in the state storage unit 7 .

When an earthquake occurs, the remote monitoring device 8 acquires earthquake information from the earthquake information distribution service. The remote monitoring device 8 acquires state information of the plurality of elevators 1 from the state storage unit 7 of the polling device 4 . Using the earthquake information and the status information, the remote monitoring device 8 creates a polling order for inquiring about the status of the elevators 1 whose status information is unconfirmed. The remote monitoring device 8 transmits polling sequence information to the polling unit 6 of the polling device 4 .

When the polling unit 6 in the polling device 4 receives information on the polling order, it performs a polling operation of sending a signal to inquire about the status of the plurality of elevators 1 according to the polling order.

In the elevator 1 to which the signal inquiring about the status is transmitted, the individual monitoring device 2 receives the signal. The individual monitoring device 2 transmits information indicating that the elevator 1 is in a stopped state or information indicating that the elevator 1 remains in a non-stop state to the receiving section 5 of the polling device 4 .

For example, the remote monitoring device 8 repeats the operation of creating a polling sequence until the percentage of elevators 1 that are in the unconfirmed state becomes smaller than a specified value.

For example, an elevator maintenance company lists elevators 1 whose status information is in a stopped state in the maintenance list. The elevator maintenance company dispatches workers to the elevators 1 listed in the maintenance list. After that, the worker confirms the safety of the elevator 1 and restores the elevator 1 to normal operation.

Next, the unconfirmed state of the state information stored in the state storage unit 7 of the polling device 4 will be described with reference to FIG.
FIG. 2 is a conceptual diagram showing status information stored in a polling device to which the elevator remote monitoring device according to the first embodiment is applied.

　In FIG. 2, the area surrounded by the dashed line represents the elevator 1 whose state information is in the stopped state. A range surrounded by a dashed line represents elevators 1 whose status information is in an unconfirmed state.

If the communication line is congested after an earthquake occurs, the information that the elevator 1 is in a stopped state sent from the individual monitoring device 2 may not reach the receiving unit 5 of the polling device 4. In this case, the information indicating that the elevator 1 is in a stopped state is interrupted. In the state information stored in the state storage unit 7, the elevator 1 is in an unconfirmed state. In the state information stored in the state storage unit 7, an elevator 1 in an unconfirmed state is an elevator 1 that is unknown whether it is in a stopped state or a non-stopped state.

Next, with reference to FIG. 3, the process of creating polling order information by the remote monitoring device 8 will be described.
FIG. 3 is a block diagram of a remote monitoring device for an elevator according to Embodiment 1. FIG.

As shown in FIG. 3, the remote monitoring device 8 includes a storage unit 11, an earthquake information collection unit 12, an outage probability calculation unit 13, a state correspondence unit 14, an initial range setting unit 15, an individual range setting unit 16, and a outage ratio calculation unit. It includes a section 17 , a priority search setting section 18 , an order creation section 19 and a start determination section 20 .

The storage unit 11 stores information.

When an earthquake occurs, the earthquake information collection unit 12 collects earthquake information, including information on seismic acceleration on the ground surface at multiple observation points, from the earthquake information distribution service.

The outage probability calculation unit 13 acquires earthquake information from the earthquake information collection unit 12 . The stop probability calculation unit 13 acquires from the first storage device 9 elevator information including information on the location of the building in which each of the plurality of elevators 1 is installed. A stop probability calculation unit 13 acquires from the second storage device 10 past performance information in which whether each of the plurality of elevators 1 has stopped or not stopped due to a past earthquake is associated with information on the past earthquake. do.

When an earthquake occurs, the stop probability calculation unit 13 calculates the stop probability that each of the plurality of elevators 1 will be stopped due to the earthquake, based on the earthquake information, the elevator information, and the past record information. . The stop probability calculation unit 13 causes the storage unit 11 to store information on the stop probability.

The state correspondence unit 14 acquires stop probability information from the storage unit 11 . The state correspondence unit 14 acquires from the state storage unit 7 of the polling device 4 state information indicating whether each of the plurality of elevators 1 is in a stopped state, a non-stopped state, or an unconfirmed state. The state correspondence unit 14 adds state information to the information about the probability of stopping, thereby associating each piece of information on the plurality of elevators 1 with one of a stopped state, a non-stopped state, and an unconfirmed state.

The initial range setting unit 15 acquires outage probability information to which state information is added from the state correspondence unit 14 . The initial range setting unit 15 applies a linear search method to the stop probability information to which the state information is added, thereby specifying the elevator 1 with the lowest stop probability among the plurality of elevators 1 in the stopped state. For example, the initial range setting unit 15 sets the range of stop probability from the value of the stop probability of the elevator 1 with the lowest stop probability to 100% as the initial search range.

The individual range setting unit 16 acquires stop probability information to which state information is added from the initial range setting unit 15 . The individual range setting unit 16 sets a plurality of individual search ranges by dividing the initial search range set by the initial range setting unit 15 using the stop probability information into a plurality of stop probability ranges.

The stoppage ratio calculation unit 17 acquires stoppage probability information to which state information is added from the individual range setting unit 16 . The stoppage ratio calculation unit 17 calculates the stoppage ratio using the information on the stoppage probability to which the state information is added. At this time, the stop ratio calculation unit 17 calculates the stop ratio corresponding to each of the plurality of individual search ranges set by the individual range setting unit 16 based on the following formula (1).
Stop ratio = number of stop states / (number of stop states + number of non-stop states) (1)

According to the formula (1), the stop ratio calculation unit 17 calculates the sum of the number of elevators 1 in a stopped state and the number of elevators 1 in a non-stopped state in a plurality of elevators 1 included in a certain individual search range. The quotient obtained by dividing the number of elevators 1 is set as the stop ratio of the individual search range. The stop ratio calculator 17 creates stop ratio information corresponding to each of the plurality of individual search ranges.

The focused search setting unit 18 acquires stop ratio information and stop probability information to which state information is added from the stop ratio calculation unit 17 . The focused search setting unit 18 identifies the individual search range with the smallest stop probability value among one or more individual search ranges in which the value of the stop ratio is equal to or greater than the prescribed allocation threshold, and sets it as the focused search range. The focused search setting unit 18 sets the plurality of elevators 1 included in the focused search range as the plurality of focused search elevators. Further, the focused search setting unit 18 sets a plurality of elevators 1 having a lower probability of stopping than the elevators 1 included in the focused search range among the plurality of elevators 1 as the plurality of focused search elevators.

The order creation unit 19 acquires stop probability information to which state information is added and information on a plurality of priority search elevators from the priority search setting unit 18 . The order creation unit 19 uses the information of the stop probability to which the state information is added and the information of the plurality of priority search elevators to identify the plurality of elevators 1 included in the plurality of priority search elevators and whose state information is in an unconfirmed state. identify. The order creation unit 19 creates polling order information in which the plurality of elevators 1 included in the plurality of priority search elevators and whose status information is in an unconfirmed state are arranged in descending order of the stop probability. The order creating unit 19 transmits polling order information to the polling unit 6 of the polling device 4 .

The start determination unit 20 starts measuring time when the earthquake information collection unit 12 collects earthquake information. The start determination unit 20 sets the measured time to zero when the order creation unit 19 transmits the polling order information to the polling unit 6 of the polling device 4 . When the measured time reaches zero, the start determination unit 20 restarts time measurement.

The start determination unit 20 acquires state information from the state storage unit 7 of the polling device 4 when the measured time exceeds the specified time. The start determination unit 20 calculates the unconfirmed ratio in the state information based on the following formula (2).
Unconfirmed rate = number of unconfirmed states / (number of stopped states + number of non-stopped states + number of unconfirmed states) (2)

According to the formula (2), the start determination unit 20 determines the number of elevators 1 in the unconfirmed state by summing the number of elevators 1 in the stopped state, the number of elevators 1 in the non-stop state, and the number of elevators 1 in the unconfirmed state included in the state information. The quotient obtained by dividing the number of elevators 1 is set as the unconfirmed ratio in the state information. The start determination unit 20 determines whether or not the value of the unconfirmed rate is greater than a prescribed start threshold.

If the value of the unconfirmed rate is greater than the prescribed start threshold, the start determination unit 20 sends a command to the state handling unit 14 to acquire stop probability information. After that, the remote monitoring device 8 sequentially performs operations for creating polling order information.

If the value of the unconfirmed rate is equal to or less than the specified start threshold, the start determination unit 20 terminates the operation of the remote monitoring device 8 to create polling order information. For example, if the initiation threshold is set to 0, the remote monitoring device 8 creates polling order information until there are no more unconfirmed elevators 1 . In this case, the polling device 4 performs the polling operation until there are no elevators 1 in the unconfirmed state.

Next, the operation of the stop probability calculation unit 13 predicting the stop probability and creating stop probability information will be described with reference to FIGS. 4 and 5. FIG.

FIG. 5 is a diagram showing stop probability information calculated by the stop probability calculation unit of the remote monitoring device for elevators according to the first embodiment.

Each of the plurality of graphs shown in FIG. 4 is a graph representing the relationship between the stop probability value and the seismic acceleration value. The vertical axis of the graph is the stop probability value of the elevator 1 provided in a certain building. The horizontal axis of the graph is the value of seismic acceleration on the ground surface that occurs in the building during an earthquake. The unit of the seismic acceleration is [GAL].

The stop probability calculation unit 13 uses past performance information in which whether each of the plurality of elevators 1 has stopped or not stopped due to a past earthquake is associated with the scale of the past earthquake, and calculates a stop probability curve. Learn model parameters. For example, the outage probability calculator 13 learns the parameters of the outage probability curve model before an earthquake occurs. The stop probability calculator 13 determines the parameters of the stop probability curve model for each of the plurality of elevators 1 installed in the plurality of buildings.

When an earthquake occurs, the stop probability calculation unit 13 calculates the stop probability of each of the plurality of elevators 1 using information on the earthquake and information on the model of the stop probability curve. The stop probability calculation unit 13 calculates the stop probability of each elevator 1 by applying the seismic acceleration value on the ground surface of the building in which the elevator 1 is installed to a model of the stop probability curve. do.

In the graph of FIG. 4, the white circles represent past performance information indicating that the elevator 1 installed in a certain building was in a stopped state or was in a non-stopped state due to past earthquakes. When the elevator 1 has stopped due to past earthquakes, a white circle is drawn at a position on the vertical axis indicating that the probability of stopping is 100%. If the elevator 1 was in a non-stop state in past earthquakes, a white circle is drawn on the vertical axis at a position indicating that the stop probability is 0%. In the graph, the curve X represents a model of the outage probability curve for a certain building learned by the outage probability calculation unit 13 . The parameters of the stopping probability curve model are determined to fit the stopping probability curve to the points represented by the open circles. In the graph, black circles represent the relationship between the seismic acceleration value on the ground surface of the most recent earthquake and the stop probability value of the elevator 1 calculated from the seismic acceleration.

As shown in FIG. 5, the stop probability information is information in which "building" information, "elevator No." information provided in the building, and "stop probability [%]" information are associated with each other. be. The information on the probability of stopping is information in a table in which the information on the "Elevator No." is arranged in descending order of the "probability of stopping [%]". "Building" information is information for identifying a building. The information of "Elevator No." is information indicating a unique number of the elevator 1 provided in the building. The information of “stop probability [%]” is information indicating the stop probability of the elevator 1 calculated by the stop probability calculation unit 13 .

Next, state information of the plurality of elevators 1 immediately after the occurrence of an earthquake will be described with reference to FIG.

FIG. 6 is a graph showing the relationship between the stop probabilities of the plurality of elevators 1 and the state information associated by the state correspondence unit 14. As shown in FIG. The vertical axis of the graph represents state information indicating whether the elevator 1 is in a stopped state, a non-stopped state, or an unconfirmed state immediately after the earthquake. The horizontal axis of the graph is the stop probability of the elevator 1 .

As shown in the graph, there are elevators 1 that have been confirmed to be in a stopped or non-stopped state immediately after the earthquake and elevators 1 whose current state is unconfirmed.

Next, an example of an initial search range set by the initial range setting unit 15 and a plurality of individual search ranges set by the individual range setting unit 16 will be described with reference to FIG.
FIG. 7 is a diagram showing the relationship between the stop probability and the state information indicating the initial search range and a plurality of individual search ranges set by the remote monitoring device for the elevator according to the first embodiment.

FIG. 7 is a graph showing the relationship between the stop probabilities and the state information of the plurality of elevators 1 for which the initial search range and the plurality of individual search ranges are set. As shown in the graph, the initial search range is a range from the stop probability of the elevator 1 with the lowest stop probability among the elevators 1 in the stopped state to the stop probability of 100%. Each of the plurality of individual search ranges is a range obtained by dividing the initial search range into ranges of stopping probabilities.

Next, with reference to FIG. 8, the process of creating polling order information by the remote monitoring device 8 will be described.
FIG. 8 is a flow chart for explaining an outline of processing for creating polling order information by the elevator remote monitoring device according to the first embodiment.

When an earthquake occurs, the remote monitoring device 8 starts processing to create polling order information.

In step S001, the earthquake information collection unit 12 collects earthquake information from the earthquake information distribution service. The start determination unit 20 starts measuring time. The stop probability calculation unit 13 calculates stop probabilities in the plurality of elevators 1 .

After that, the operation of step S002 is performed. In step S002, the start determination unit 20 determines whether or not the measured time has exceeded the specified time.

In step S002, if the measured time does not exceed the prescribed time, the start determination unit 20 repeats the operation of step S002.

In step S002, when the measured time exceeds the prescribed time, the operation of step S003 is performed. In step S003, the start determination unit 20 calculates the unconfirmed ratio. The start determination unit 20 determines whether or not the value of the unconfirmed rate is greater than a prescribed start threshold.

In step S003, if the value of the unconfirmed rate is greater than the prescribed start threshold, the operation of step S004 is performed. In step S004, the state association unit 14 adds state information to the information on the probability of stopping, thereby associating each of the information on the plurality of elevators 1 with one of the stopped state, the non-stopped state, and the unconfirmed state.

After that, the operation of step S005 is performed. In step S005, the initial range setting unit 15 sets an initial search range.

After that, the operation of step S006 is performed. In step S006, the individual range setting unit 16 sets an individual search range.

After that, the operation of step S007 is performed. In step S007, the stop ratio calculator 17 calculates stop ratios corresponding to each of the plurality of individual search ranges.

After that, the operation of step S008 is performed. In step S008, the focused search setting unit 18 sets a plurality of focused search elevators.

After that, the operation of step S009 is performed. In step S009, the order creating unit 19 creates polling order information. The order creating unit 19 transmits polling order information to the polling unit 6 of the polling device 4 .

After that, the operation of step S010 is performed. In step S010, the start determination unit 20 sets the measured time to zero. The start determination unit 20 starts measuring time again.

After that, the operations after step S002 are repeated.

In step S003, if the value of the unconfirmed rate is equal to or less than the prescribed start threshold, the remote monitoring device 8 terminates the process of creating polling order information.

According to the first embodiment described above, the remote monitoring device 8 includes the outage probability calculation unit 13, the state correspondence unit 14, the initial range setting unit 15, and the order creation unit 19. Remote monitoring device 8 creates a polling order to include elevator 1, which has a probability of being stopped within the initial search range. The initial search range includes stop probabilities in which elevators 1 in a stopped state and elevators 1 in a non-stopped state coexist. Therefore, it is possible to effectively inquire about the state of the elevator 1 when an earthquake occurs.

In addition, the remote monitoring device 8 includes an individual range setting unit 16 and a stop ratio calculation unit 17. Remote monitoring device 8 creates a polling sequence that includes elevators with outage probabilities for individual search ranges whose outage percentage values exceed a defined threshold. The remote monitoring device 8 creates a polling sequence based on the elevator 1 outage probability and the current percentage of elevator 1 outages. Therefore, it is possible to more effectively inquire about the status of the elevator 1 .

In addition, the remote monitoring device 8 includes a priority search setting unit 18 and an order creation unit 19 . The remote monitoring device 8 creates a polling order in which a plurality of priority search elevators are arranged in descending order of stop probability. On the other hand, the elevator 1, which has a higher probability of stopping than the plurality of priority search elevators, has a high probability of being stopped. Therefore, the remote monitoring device 8 can suppress inquiring about the state of elevators that are likely to be stopped. As a result, it is possible to quickly distinguish between the elevator 1 to which the notification of the stop state has not been received and the elevator 1 which remains in the non-stop state.

It should be noted that the remote monitoring device 8 may be applied to remote monitoring of elevators 1 such as escalators, moving walkways, etc. during an earthquake.

Note that the initial range setting unit 15 applies a binary search method to a table in which the information of the plurality of elevators 1 to which the state information is added is arranged in the order of stop probability. Among them, the elevator 1 with the lowest probability of stopping may be specified.

Note that the order creation unit 19 may create a polling order in which a plurality of elevators 1 having stop probabilities included in the initial search range set by the initial range setting unit 15 are arranged in descending order of stop probability.

The order creation unit 19 identifies individual range setting units in which the values of the stop ratio are within a specified value range, and arranges the elevators 1 having the stop probability included in the individual range setting units in the highest order. You may create an ordered polling order.

For example, each function of the remote monitoring device 8 is implemented by a processing circuit. For example, each function of the remote monitoring device 8 is collectively realized by a processing circuit.

A part of each function of the remote monitoring device 8 may be realized by dedicated hardware 200, and the other part may be realized by software or firmware.
