Detailed Description

Embodiments of the present invention will be described with reference to the accompanying drawings. In the drawings, the same or corresponding portions are denoted by the same reference numerals, and repetitive description thereof will be appropriately simplified or omitted. The object of the present invention is not limited to the following embodiments, and modifications of any of the components of the embodiments or omission of any of the components of the embodiments can be made within the scope of the present invention.

Embodiment 1.

Fig. 1 is a structural diagram of an elevator system 1 according to embodiment 1.

The elevator system 1 includes an elevator 2. The elevator 2 is applied, for example, to a facility 3 having a plurality of floors. In the installation 3, a hoistway 4 of the elevator 2 is provided. The hoistway 4 is a vertically long space extending across a plurality of floors. A pit is provided at the lower end of the hoistway 4. Each floor is provided with a landing 5 adjacent to the hoistway 4. Landing doors 6 are provided at the landing 5 of each floor. Landing doors 6 are doors that divide hoistway 4 and landing 5. The elevator 2 includes a hoisting machine 7, main ropes 8, a car 9, a counterweight 10, and a control panel 11.

The hoisting machine 7 is disposed, for example, in an upper portion or a lower portion of the hoistway 4. For example, when a machine room of the elevator 2 is provided above the hoistway 4, the hoisting machine 7 may be disposed in the machine room. The hoisting machine 7 includes a motor and a sheave. The motor of the hoisting machine 7 is a device that generates driving force. The sheave of the hoisting machine 7 is a device that rotates by a driving force generated by a motor of the hoisting machine 7.

The main rope 8 is wound around a sheave of the hoisting machine 7. The main rope 8 supports the load of the car 9 on one side of the sheave of the hoisting machine 7. The main ropes 8 support the load of the counterweight 10 on the other side of the sheave of the hoisting machine 7. The main rope 8 is moved by rotation of the sheave of the hoisting machine 7 so as to be pulled by the sheave of the hoisting machine 7 or so as to be discharged from the sheave of the hoisting machine 7.

The car 9 is a device that travels in the vertical direction in the hoistway 4 to convey a user of the elevator 2 or the like between a plurality of floors. The car 9 travels in the vertical direction in the hoistway 4 in association with the movement of the main rope 8 by the rotation of the sheave of the hoisting machine 7. The car 9 is provided with a car door 12. The car door 12 is a door that divides the interior and exterior of the car 9. The car door 12 is a device for opening and closing the landing door 6 of any floor in association with each other when the car 9 stops at that floor.

The counterweight 10 is a device for balancing the load applied to both sides of the sheave of the hoisting machine 7 with respect to the car 9. The counterweight 10 travels in the hoistway 4 in the opposite direction to the car 9 in the up-down direction in conjunction with the movement of the main rope 8 by the rotation of the sheave of the hoisting machine 7.

The control panel 11 is a device for controlling the operation of the elevator 2. The control panel 11 is disposed, for example, at an upper portion or a lower portion of the hoistway 4. For example, when a machine room of the elevator 2 is provided above the hoistway 4, the control panel 11 may be disposed in the machine room. The operation of the elevator 2 controlled by the control panel 11 includes the running of the car 9, the opening and closing of the car door 12, and the like. For example, the control panel 11 causes the car 9 to travel between a plurality of floors based on the registered call. When the car 9 is stopped at an arbitrary floor, the control panel 11 opens the car door 12 in conjunction with the landing door 6 and the car door 12. The control panel 11 maintains the fully opened state of the car door 12 and the landing door 6 for a predetermined door opening time. After the door opening time has elapsed since the car 9 was fully opened, the control panel 11 causes the landing door 6 to close the car door 12 in conjunction with the car door 12.

An abnormality detection unit 13 is provided in the facility 3 to which the elevator 2 is applied. The abnormality detection unit 13 is a part that detects an abnormality in the facility 3. The abnormality detected by the abnormality detecting unit 13 is, for example, a device failure of the elevator 2 applied to the facility 3, a device failure of the facility 3, a partial damage of the facility 3, or the like. The abnormality detection unit 13 outputs information of the detected abnormality to the remote monitoring device 15 or the like. The abnormality detection unit 13 is, for example, a sensor or the like provided in the equipment of the elevator 2 or the equipment of the facility 3.

The elevator 2 is provided with a flooding detection unit 14. The flooding detection unit 14 is a portion that detects flooding of the hoistway 4. The flooding detection unit 14 is disposed in the hoistway 4. The flooding detection unit 14 may be disposed in a pit, for example. In this example, the flooding detection unit 14 outputs information of the detected flooding to the control panel 11. The flooding detection unit 14 is, for example, a flooding sensor.

The elevator system 1 is provided with a remote monitoring device 15. The remote monitoring device 15 is a device for remote monitoring of the state of the elevator 2, and the like. The remote monitoring device 15 is connected to the control panel 11 or the like so as to be able to collect status information of the elevator 2. The remote monitoring device 15 collects, for example, information input to the control panel 11, information output from the control panel 11, and the like as status information of the elevator 2. The information collected by the remote monitoring device 15 is transmitted to a device or the like provided in the information center 17 via a communication network 16 such as the internet or a telephone network. The information center 17 is a point where the status information of the elevator 2 is collected and managed. The remote monitoring device 15 receives a control signal of the elevator 2 from the outside of the facility 3 or the like where the elevator 2 is installed through the communication network 16. The remote monitoring device 15 outputs the received control signal to the control panel 11.

The elevator system 1 includes a management system 18. The management system 18 is a system for performing remote management of the elevator 2. The management system 18 is, for example, a system including one or more server devices and the like. The server of the management system 18 is disposed in the information center 17, for example. The management system 18 is connected to the communication network 16. Some or all of the functions of management system 18 may also be installed by processing on cloud services as well as stored resources. The management system 18 collects status information of the elevator 2, for example, by a remote monitoring device 15 or the like of the elevator 2. The management system 18 includes an acquisition unit 19, a command unit 20, a monitoring processing unit 21, and a management processing unit 22.

The acquisition unit 19 is a part that acquires information from a system external to the management system 18 via the communication network 16 or the like. The external system is, for example, a weather information system 23 which distributes weather information. The weather information system 23 is, for example, a system of an organization such as a public institution or a civil weather company that processes weather information as in the weather bureau of japan. In this example, the weather information system 23 issues information indicating the emergency degree of the flooding disaster at each site. The information to be distributed is, for example, the risk distribution of a heavy rain alarm (a water-immersed disaster) issued by the weather bureau, or the same information as the risk distribution. The information to be distributed is, for example, information indicating the degree of urgency at each location in five levels, i.e., a risk level of 0 to a risk level of 4. The acquisition unit 19 successively acquires the emergency degree of the water-immersed disaster at the location where the facility 3 to which the elevator 2 is applied is installed from the weather information system 23. In this example, the acquisition unit 19 periodically acquires the degree of urgency. The period for obtaining the degree of urgency is, for example, 10 minutes.

The command unit 20 is a part that outputs a control signal of the evacuation function from the submergence evacuation to the elevator 2 through the communication network 16, the remote monitoring device 15, and the like. The evacuation function is a function of the elevator 2 for avoiding or suppressing damage due to the hoistway 4 being immersed in water. The back-off function includes, for example, upper floor standby and operation suspension. The upper floor standby is a back-off function in which the standby floor of the car 9 is set as the upper floor. Here, the waiting floor of the car 9 is a floor at which the car 9 waits when stopping in an undirected manner. In normal operation, the standby floor is set as, for example, a vestibule floor of the facility 3. The upper floor is a floor above a floor set in advance in the facility 3. The upper floor is, for example, any floor above the vestibule floor. The upper floor set as the waiting floor may be the uppermost floor of the facility 3. The operation suspension is a suspension function for suspending the car 9 without traveling. At this time, the elevator 2 stops in a state where the car 9 stops at an upper floor, for example.

The command unit 20 outputs a control signal based on the information acquired by the acquisition unit 19. The command unit 20 is preset with a 1 st reference value and a 2 nd reference value related to the degree of emergency. The 2 nd reference value is set to a value equal to or smaller than the 1 st reference value. The 1 st reference value is a reference value of the degree of urgency for starting the backoff function. The 2 nd reference value is a reference value of the degree of urgency for canceling the backoff function. That is, the command unit 20 outputs a control signal for starting the backoff function when the degree of emergency acquired by the acquisition unit 19 is equal to or greater than the 1 st reference value. When the degree of emergency acquired by the acquisition unit 19 is smaller than the 2 nd reference value, the instruction unit 20 outputs a control signal for releasing the backoff function. The 1 st reference value and the 2 nd reference value may be set for each type of the backoff function, for example.

The monitoring processor 21 receives input of monitoring information. The monitoring information is information entered by a monitoring person of the elevator 2. The monitoring person of the elevator 2 is, for example, an operator who monitors the elevator 2 as a service in the information center 17. The monitoring information is, for example, information indicating that an abnormality has occurred in the elevator 2. When receiving notification of occurrence of an abnormality from a user or the like of the elevator 2, for example, a monitoring person inputs monitoring information indicating occurrence of an abnormality with respect to the elevator 2 to the monitoring processor 21. When an abnormality occurs in the elevator 2, a monitoring person dispatches a maintenance person corresponding to the abnormality to the elevator 2. When the abnormality is eliminated by the handling of the maintenance personnel, the monitoring personnel inputs monitoring information indicating that the abnormality has been eliminated to the monitoring processing section 21.

The management processing unit 22 is a unit that receives management operations of a manager of the elevator 2. The management personnel accesses the management processing unit 22 of the management system 18, for example, using the management terminal 24 connected to the communication network 16. The management terminal 24 is, for example, a general-purpose information terminal such as a personal computer. In this case, the management processing unit 22 operates as a web server or the like, for example. The manager views the status information of the elevator 2 through an application such as a web browser on the management terminal 24. The manager performs a management operation of setting change by the management terminal 24. The management operation of setting change includes, for example, setting of the 1 st reference value and the 2 nd reference value.

Fig. 2 is a diagram showing an example of a setting change screen in the management system 18 according to embodiment 1.

Fig. 2 shows an example of a screen displayed on the management terminal 24.

The management terminal 24 selects the elevator 2 to be the setting change target. In this example, elevator 2 is selected by pulling down. In this example, elevator 2 of "001 car" is selected.

The management terminal 24 sets the 1 st reference value and the 2 nd reference value for each backoff function. In this example, the 1 st reference value and the 2 nd reference value are selected by pull-down. In this example, the 1 st reference value for starting the operation suspension is set to the risk level 4. At this time, for example, when the degree of urgency acquired by the acquisition unit 19 increases from the degree of danger 3 to the degree of danger 4, the instruction unit 20 outputs a control signal to start the operation suspension. The 2 nd reference value for canceling the operation suspension is set to the risk level 3. At this time, for example, when the degree of urgency acquired by the acquisition unit 19 decreases from the degree of danger 3 to the degree of danger 2, the instruction unit 20 outputs a control signal for canceling the operation suspension. In this example, the 1 st reference value for starting the standby at the upper floor is set to the risk level 3. At this time, for example, when the degree of urgency acquired by the acquisition unit 19 increases from the degree of danger 2 to the degree of danger 3, the instruction unit 20 outputs a control signal to start the standby of the upper floor. The 2 nd reference value for canceling the standby at the upper floor is set to the risk level 3. At this time, for example, when the degree of urgency acquired by the acquisition unit 19 decreases from the degree of danger 3 to the degree of danger 2, the instruction unit 20 outputs a control signal for canceling the standby at the upper floor.

The management terminal 24 sets the validity or invalidity of the automatic control for each backoff function. In this example, a switch is used to select whether the automatic control is active or inactive. In this example, the automatic control of the operation suspension is set to be effective. Further, automatic control of the upper floor standby is set to be effective. Regarding the backoff function for which the automatic control is set to be disabled, the command unit 20 does not output a control signal for the backoff function according to the change in the degree of urgency acquired by the acquisition unit 19.

In the management terminal 24, the validity or invalidity of the notification function is set. The notification function is a function of notifying a manager from the management system 18 according to a change in the degree of urgency acquired by the acquisition unit 19. The management system 18 notifies the management personnel, for example, by an email or push notification of the management processing unit 22. In this example, a switch is used to select whether the notification function is active or inactive.

The notification function is preset with a rising reference value and a falling reference value. As the notification function, the management processing unit 22 notifies the manager, for example, when the degree of urgency acquired by the acquisition unit 19 is equal to or greater than the ascent reference value and when the degree of urgency acquired by the acquisition unit 19 is less than the descent reference value. In this example, the rising reference value is designated as the risk level 2. Further, the descent reference value is designated as the risk level 2. Therefore, the management processing unit 22 notifies the management staff when the degree of urgency acquired by the acquisition unit 19 increases from the degree of danger 1 to the degree of danger 2 and when the degree of urgency acquired by the acquisition unit 19 decreases from the degree of danger 2 to the degree of danger 1.

The reference value for the rise may be set according to the 1 st reference value of any backoff function. The drop reference value may be set based on the 2 nd reference value of any backoff function. The validity or invalidity of the notification function may be set for the notification based on the ascending reference value and the notification based on the descending reference value, respectively.

Next, an example of the function of the elevator system 1 will be described with reference to fig. 2.

Here, when setting is performed as shown in fig. 2, a case will be described in which, in a place where the facility 3 to which the elevator 2 is applied is provided, the emergency level is raised from the risk level 0 to the risk level 4 in order due to rainfall, and then the emergency level is lowered from the risk level 4 to the risk level 0 in order.

Before rainfall, the acquisition unit 19 acquires the degree of urgency of the degree of danger 0 from the weather information system 23. At this time, the elevator 2 is in normal operation.

Then, when the rainfall becomes strong, the acquisition unit 19 acquires the degree of urgency of the risk level 1 from the weather information system 23. At this time, the elevator 2 is in normal operation.

Then, when the emergency of the flooding disaster increases due to an increase in the precipitation amount or the like, the acquisition unit 19 acquires the emergency of the risk level 2 from the weather information system 23. Since the degree of urgency is equal to or greater than the reference value for the rise of the notification function, the management processing unit 22 notifies the manager of the degree of urgency. At this time, the elevator 2 is in normal operation.

Then, when the emergency of the flooding disaster is further improved, the acquiring unit 19 acquires the emergency of the risk level 3 from the weather information system 23. At this time, the degree of urgency is equal to or greater than the 1 st reference value of the upper floor standby. Since the automatic control is set to be active for the upper floor standby, the command unit 20 outputs a control signal for starting the upper floor standby to the control panel 11 of the elevator 2 via the communication network 16 and the remote monitoring device 15. Here, the management processing unit 22 may notify the manager when the degree of emergency is equal to or greater than the 1 st reference value of the upper floor standby. The control panel 11 sets the waiting floor of the car 9 to an upper floor such as the uppermost floor, for example, in response to a control signal from the command unit 20.

Then, when the flooding disaster further progresses, the acquiring unit 19 acquires the degree of urgency of the degree of danger 4 from the weather information system 23. In this case, the degree of urgency is equal to or greater than the 1 st reference value for the operation suspension. Since the automatic control is set to be active in the operation suspension, the command unit 20 outputs a control signal for starting the operation suspension to the control panel 11 of the elevator 2 via the communication network 16 and the remote monitoring device 15. Here, the management processing unit 22 may notify the manager when the degree of urgency is equal to or greater than the 1 st reference value for the operation suspension. The control panel 11 stops the operation of the elevator 2 according to a control signal from the command unit 20. Before stopping the operation of the elevator 2, the control panel 11 stops the car 9 at any floor of the facility 3, and allows a user who has been riding on the car 9 to get off the elevator. In this example, the control panel 11 stops the car 9 at the nearest floor and allows the user to get off the elevator.

When the hoistway 4 is immersed in water, which is detected by the immersion detection unit 14, the command unit 20 outputs a control signal for starting the evacuation function even when the degree of emergency is smaller than the 1 st reference value of the evacuation function. For example, when the flooding detection unit 14 detects that the hoistway 4 is flooded, the command unit 20 outputs a control signal for starting the operation suspension even when the degree of urgency is smaller than the 1 st reference value for the operation suspension. That is, as an output condition of the control signal for starting the retraction function, the command unit 20 prioritizes the detection of the immersion of the hoistway 4 by the immersion detection unit 14 over the change in the degree of emergency acquired by the acquisition unit 19.

Then, when the emergency is alleviated due to a decrease in the precipitation amount or the like, the obtaining unit 19 obtains the emergency of the risk level 3 from the weather information system 23. In this case, since the degree of emergency is equal to or greater than the 2 nd reference value for the operation suspension, the command unit 20 does not output a control signal for releasing the operation suspension. Further, since the degree of emergency is equal to or greater than the 2 nd reference value of the upper floor standby, the command unit 20 does not output a control signal for canceling the upper floor standby.

Then, when the emergency is further alleviated, the obtaining unit 19 obtains the emergency of the risk level 2 from the weather information system 23. At this time, the degree of urgency is smaller than the 2 nd reference value of the operation suspension. Since the automatic control is set to be active in response to the suspension of operation, the command unit 20 outputs a control signal for releasing the suspension of operation to the control panel 11 of the elevator 2 via the communication network 16 and the remote monitoring device 15. In addition, the degree of urgency is smaller than the 2 nd reference value of the upper floor standby. Since the automatic control is set to be active in the upper floor standby mode, the command unit 20 outputs a control signal for canceling the suspension of operation to the control panel 11 of the elevator 2 via the communication network 16 and the remote monitoring device 15. Here, the management processing unit 22 may notify the manager when the degree of urgency is smaller than the 2 nd reference value for the operation suspension. Here, the management processing unit 22 may notify the manager when the degree of urgency is smaller than the 2 nd reference value of the upper floor standby. The control panel 11 resumes the operation of the elevator 2 in response to a control signal from the command unit 20. The control panel 11 releases the upper floor standby in response to the control signal from the command unit 20.

Here, when the hoistway 4 is immersed in water, which is detected by the immersion detection unit 14, the command unit 20 does not output a control signal for releasing the retraction function even when the degree of emergency is smaller than the 2 nd reference value of the retraction function. The command unit 20 suspends the release of the retraction function until the detection of the immersion of the hoistway 4 by the immersion detection unit 14 is released. When the emergency degree is smaller than the 2 nd reference value of the retraction function when the immersion detection of the hoistway 4 by the immersion detection unit 14 is released, the command unit 20 outputs a control signal for releasing the retraction function. That is, as an output condition of the control signal for canceling the retraction function, the command unit 20 prioritizes the detection of the immersion of the hoistway 4 by the immersion detection unit 14 over the change in the degree of emergency acquired by the acquisition unit 19.

In addition, when the abnormality detection unit 13 detects an abnormality in the facility 3, the command unit 20 may suspend the operation without outputting a control signal for canceling the backoff function even when the degree of urgency is smaller than the 2 nd reference value of the backoff function. In this case, when the degree of urgency is smaller than the 2 nd reference value of the backoff function when the abnormality detection by the abnormality detection unit 13 is released, the command unit 20 outputs a control signal for releasing the backoff function.

In addition, when the monitoring processor 21 receives the monitoring information indicating that an abnormality has occurred in the elevator 2, the instruction unit 20 may suspend the elevator without outputting a control signal for canceling the evacuation function even when the degree of urgency is smaller than the 2 nd reference value of the evacuation function. When the monitoring processor 21 receives the monitoring information indicating that the abnormality in the elevator 2 has been eliminated, the instruction unit 20 outputs a control signal for canceling the evacuation function if the degree of urgency is smaller than the 2 nd reference value of the evacuation function.

Then, when the emergency is further alleviated, the obtaining unit 19 obtains the emergency of the risk level 1 from the weather information system 23. Since the degree of urgency is smaller than the decrease reference value of the notification function, the management processing unit 22 notifies the manager. At this time, the elevator 2 is in normal operation.

Then, as the emergency is further alleviated, the obtaining unit 19 obtains the emergency degrees of the risk degree 1 and the risk degree 0 in order from the weather information system 23. At this time, the elevator 2 is in normal operation.

When the automatic control of the backoff function is set to be invalid, the command unit 20 does not output a control signal for starting the backoff function when the degree of urgency is equal to or greater than the 1 st reference value of the backoff function. On the other hand, when the degree of urgency is equal to or greater than the 1 st reference value of the backoff function, the management processing unit 22 notifies the manager. The manager who receives the notification performs a management operation of, for example, starting the back-off function from a remote place through the management terminal 24. When the management processing unit 22 receives the management operation, the command unit 20 outputs a control signal for starting the retraction function to the control panel 11 of the elevator 2.

When the automatic control of the backoff function is set to be invalid, the command unit 20 does not output a control signal for canceling the backoff function when the degree of urgency is smaller than the 2 nd reference value of the backoff function. On the other hand, when the degree of urgency is smaller than the 2 nd reference value of the backoff function, the management processing unit 22 notifies the manager. The manager who receives the notification performs a management operation of releasing the back-off function from a remote place, for example, through the management terminal 24. When the management processing unit 22 receives the management operation, the command unit 20 outputs a control signal for canceling the retraction function to the control panel 11 of the elevator 2.

Next, an example of the operation of the management system 18 will be described with reference to fig. 3.

Fig. 3 is a flowchart showing an example of the operation of the management system 18 according to embodiment 1.

Fig. 3 shows an example of processing when the back-off function is started.

The management system 18 performs the processing shown in fig. 3 for each backoff function, for example.

In step S1, the management processing unit 22 receives a management operation for setting change. Then, the process in the management system 18 advances to step S2.

In step S2, the acquisition unit 19 acquires the emergency level of the water flooding disaster at the location where the facility 3 to which the elevator 2 is applied is provided, from the weather information system 23. Then, the process in the management system 18 advances to step S3.

In step S3, the instruction unit 20 determines whether or not the degree of urgency acquired by the acquisition unit 19 satisfies the start condition of the backoff function. In this example, the instruction unit 20 determines whether or not the degree of urgency has become equal to or greater than the 1 st reference value. In the case where the determination result is no, the process in the management system 18 advances to step S2. If the determination result is yes, the process in the management system 18 advances to step S4.

In step S4, the instruction unit 20 determines whether or not the automatic control is set to be effective for the backoff function that has satisfied the start condition. If the determination result is yes, the process in the management system 18 advances to step S5. In the case where the determination result is no, the process in the management system 18 advances to step S6.

In step S5, the command unit 20 outputs a control signal for starting the backoff function to the control panel 11. Then, the management system 18 ends the processing at the start of the back-off function.

In step S6, the management processing unit 22 notifies the manager of the elevator 2 that the start condition of the backoff function has been satisfied. Then, the process in the management system 18 advances to step S7.

In step S7, the management processing section 22 waits for input of a management operation from the manager who received the notification. Then, the process in the management system 18 advances to step S8.

In step S8, the management processing unit 22 determines whether or not an input of a management operation for starting the backoff function from a remote location is received from the manager. If the determination result is yes, the process in the management system 18 advances to step S5. In the case where the determination result is no, the process in the management system 18 advances to step S7.

When the back-off function is released, the same processing as in fig. 3 is performed. In this case, in the same process as step S3, the instruction unit 20 may determine whether or not the flooding detection unit 14 detects the flooding. In this case, when the flooding detection unit 14 detects flooding, the command unit 20 determines that the release condition of the back-off function is not satisfied.

The degree of urgency may be information expressed in 6 or more levels. The degree of urgency may be information expressed in less than 4 levels. The degree of urgency may also be information represented by a continuous numerical value.

As described above, the elevator system 1 according to embodiment 1 includes the remote monitoring device 15 and the management system 18. The remote monitoring device 15 is provided in the facility 3 to which the elevator 2 is applied. The remote monitoring device 15 is connected to a control panel 11 for controlling the operation of the elevator 2. The remote monitoring device 15 provides status information of the elevator 2 to the management system 18. The management system 18 includes an acquisition unit 19 and a command unit 20. The obtaining unit 19 successively obtains the emergency degree of the water flooding disaster at the location where the facility 3 is installed from the external weather information system 23. When the degree of emergency acquired by the acquisition unit 19 is equal to or greater than the 1 st reference value, the instruction unit 20 starts a retraction function for retracting the elevator 2 from the immersed state. The command unit 20 releases the evacuation function of the elevator 2 when the degree of emergency acquired by the acquisition unit 19 is smaller than the 2 nd reference value. The 1 st reference value and the 2 nd reference value are preset, and the 2 nd reference value is equal to or less than the 1 st reference value.

According to such a configuration, in the elevator 2, the evacuation function is released in response to a change in the emergency information from the outside such as the weather information system 23. Therefore, the back-off function from the flooding back-off is released irrespective of the operation of the manager in the facility 3. This suppresses the delay in recovery of the elevator 2 due to the delay in arrival of the manager or the like. In addition, a phenomenon due to weather disasters such as flooding may occur simultaneously in a plurality of facilities 3 managed by a manager. In this case, since the back-off function is released based on the information from the weather system, the elevator 2 can be restored without waiting for the manager to sequentially reach each facility 3. Thus, the convenience of the user is not easily impaired. Further, since the 1 st reference value related to the start of the backoff function and the 2 nd reference value related to the release of the backoff function are set independently, the reference value can be set so that the started backoff function is released after the emergency is sufficiently relaxed. This can more effectively suppress damage caused by flooding or the like.

Further, the 2 nd reference value is set lower than the 1 st reference value.

According to this configuration, the emergency is sufficiently alleviated, and then the started back-off function is released. This can more effectively suppress damage caused by flooding or the like.

The instruction unit 20 notifies the manager of the elevator 2 when the evacuation function is started. The instruction unit 20 notifies the manager of the elevator 2 when the back-off function is released.

With this configuration, the manager can more easily grasp the implementation state of the evacuation function in the elevator 2. Thereby, the elevator 2 is more easily managed.

Further, as the retraction function, the instruction unit 20 stops the operation of the elevator 2.

According to such a configuration, since the car 9 does not travel when the emergency degree of the water flooding disaster is high, damage due to flooding or the like of the car 9, a user getting trapped in the ladder, or the like is less likely to occur.

The command unit 20 sets the waiting floor of the car 9 to an upper floor above a floor preset in the facility 3 as the evacuation function.

According to this configuration, when the emergency degree of the water flooding disaster is high, the car 9 stands by at the upper floor. This makes it difficult for the car 9 in standby to be flooded or for water to flow into the car 9 in standby from the upper landing 5.

The instruction unit 20 also temporarily releases the retraction function of the elevator 2 while the abnormality detection unit 13 provided in the facility 3 detects an abnormality of the facility 3.

According to such a configuration, when an abnormality of the facility 3 is detected, the elevator 2 is not restored only by the weather condition being restored. Therefore, even when the weather conditions are recovered earlier than the recovery of the facility 3, the occurrence of secondary damage in the elevator 2 can be suppressed.

The command unit 20 also suspends the release function of the elevator 2 while the hoistway 4 is immersed in water, which is detected by the immersion detection unit 14 provided in the hoistway 4.

According to such a configuration, when the hoistway 4 is detected to be immersed, the elevator 2 is not restored only by the weather condition. Therefore, even when the meteorological conditions are recovered earlier than the recovery of the drainage of the hoistway 4, etc., it is possible to suppress occurrence of secondary damage in the elevator 2 due to flooding of the car 9, etc.

The management system 18 further includes a monitoring processor 21. The monitoring processor 21 receives input of monitoring information by a monitoring person of the elevator 2. When the monitoring processor 21 receives the input of the monitoring information in which the abnormality has occurred in the elevator 2, the instruction unit 20 temporarily releases the retraction function of the elevator 2 until the monitoring information receiver receives the input of the monitoring information in which the abnormality has been removed.

According to such a configuration, even when abnormality or the like of the facility 3 is not detected, the elevator 2 is not restored only by the weather condition when abnormality is confirmed by notification or the like. Therefore, even when the weather conditions are recovered earlier than the recovery of the facility 3, the occurrence of secondary damage in the elevator 2 can be suppressed.

The management system 18 further includes a management processing unit 22. The management processing unit 22 receives an input of a management operation by a manager of the elevator 2. When the management processing unit 22 receives a management operation to remotely cancel the evacuation function, the instruction unit 20 causes the elevator 2 to cancel the evacuation function.

According to this configuration, even when the weather condition is not recovered, the function of the elevator 2 can be recovered according to the judgment of the manager. Therefore, the convenience of the user is less likely to be impaired. The command unit 20 may give priority to the detection of the water in the hoistway 4 by the water penetration detection unit 14 as an output condition of the control signal for canceling the retraction function over the remote cancellation based on the management operation.

In addition, for example, when a communication failure or the like occurs before the retraction function of the elevator 2 is released, the acquisition unit 19 may not be able to acquire weather information from the weather information system 23. In this case, the command unit 20 may automatically output a control signal for releasing the backoff function according to the elapse of time. For example, the instruction unit 20 determines whether or not the 1 st time has elapsed since the last emergency degree obtained by the obtaining unit 19. The 1 st time is, for example, a time preset according to an emergency acquisition cycle. When the 1 st time has elapsed, the instruction unit 20 determines that the acquisition unit 19 has failed to acquire the weather information from the weather information system 23. At this time, the command unit 20 determines whether or not the 2 nd time has elapsed since the start of the evacuation function of the elevator 2. The 2 nd time is, for example, a time such as 300 minutes, which is preset to be a time sufficient to restore the weather conditions. When the 2 nd time has elapsed, the command unit 20 outputs a control signal for releasing the backoff function to the elevator 2.

According to such a configuration, even when a communication failure or the like occurs, the backoff function is automatically released as time passes. Thus, the convenience of the user is less likely to be impaired. The command unit 20 may give priority to the detection of the water in the hoistway 4 by the water penetration detection unit 14 over the passage of the 2 nd time as an output condition of the control signal for canceling the retraction function.

Next, an example of a hardware configuration of the management system 18 will be described with reference to fig. 4.

Fig. 4 is a hardware configuration diagram of a main part of the management system 18 according to embodiment 1.

The functions of the processing in the management system 18 can be realized by a processing circuit. The processing circuit is provided with at least one processor 100a and at least one memory 100b. The processing circuit may include the processor 100a, the memory 100b, and at least one dedicated hardware 200, or the processing circuit may include at least one dedicated hardware 200 instead of the processor 100a and the memory 100b.

In the case where the processing circuit includes the processor 100a and the memory 100b, each function of the management system 18 is implemented by software, firmware, or a combination of software and firmware. At least one of the software and the firmware is described as a program. The program is stored in the memory 100b. The processor 100a realizes the functions of the management system 18 by reading out and executing programs stored in the memory 100b.

The processor 100a is also called a CPU (Central Processing Unit: central processing unit), a processing device, an arithmetic device, a microprocessor, a microcomputer, or a DSP. The Memory 100b is constituted by a nonvolatile or volatile semiconductor Memory such as RAM (Random Access Memory: random access Memory), ROM (Read Only Memory), flash Memory, EPROM (Erasable Programmable Read Only Memory: erasable programmable Read Only Memory), EEPROM (Electrically Erasable Programmable Read Only Memory: electrically erasable programmable Read Only Memory), or the like.

In the case of a processing circuit provided with dedicated hardware 200, the processing circuit is implemented, for example, by a single circuit, a complex circuit, a programmed processor, a parallel programmed processor, an ASIC (Application Specific Integrated Circuit: application specific integrated circuit), an FPGA (Field Programmable Gate Array: field programmable gate array), or a combination thereof.

The functions of the processing in the management system 18 can be realized by a processing circuit, respectively. Alternatively, the functions of the management system 18 can be realized by a processing circuit. With respect to the functions of management system 18, one part may be implemented by dedicated hardware 200 and the other part may be implemented by software or firmware. As such, the processing circuitry implements the functions of management system 18 via dedicated hardware 200, software, firmware, or a combination thereof.

In the respective embodiments described below, differences from examples disclosed in other embodiments will be described in particular detail. As for the features not described in the following embodiments, any features of examples disclosed in other embodiments may be employed.

Embodiment 2.

Fig. 5 is a structural diagram of an elevator system 1 according to embodiment 2.

The management system 18 includes a facility information storage unit 25. The facility information storage unit 25 is a part for storing the structural information of the facility 3. The configuration information of the facility 3 includes information on whether each floor is an indoor floor or an outdoor floor, and the like. The indoor floor is a floor where the landing 5 is located indoors. The outdoor floor is a floor where the landing 5 is exposed to the outside. For example, when the landing 5 is adjacent to the outer corridor at any floor of the facility 3, the floor is stored as an outdoor floor in the facility information storage unit 25. When the landing 5 is provided on the roof layer of the facility 3, the roof layer is stored as an outdoor floor in the facility information storage unit 25. In the case where the management system 18 is used for management of the elevators 2 at a plurality of facilities 3, the facility information storage unit 25 stores configuration information for each facility 3.

The command unit 20 outputs a control signal to the elevator 2 based on the configuration information of the facility 3 stored in the facility information storage unit 25.

When the elevator 2 starts to wait for the upper floor, the command unit 20 outputs a control signal to the control panel 11 so that any floor among the indoor floors of the facility 3 is the upper floor. The upper floor set at this time is, for example, the highest floor among the indoor floors of the facility 3. For example, when all floors above a certain indoor floor in the facility 3 are outdoor floors, the upper floor is set as the indoor floor.

When the elevator 2 is executing a back-off function such as waiting at an upper floor, the command unit 20 outputs a control signal to the control panel 11 so as to set the door opening time based on the configuration information of the facility 3. In this example, the instruction unit 20 outputs a control signal so that the door opening time at the outdoor floor of the facility 3 at the time when the elevator 2 starts to stand by at the upper floor is shorter than the door opening time in the normal operation. At this time, when the elevator 2 releases the upper floor standby, the instruction unit 20 outputs a control signal to return the door opening time at the outdoor floor of the facility 3 to the door opening time in the normal operation.

The command unit 20 outputs a control signal to the control panel 11 so as to set a floor on which the car 9 is stopped to allow a user who is mounted on the car 9 to get off before the operation of the elevator 2 is stopped, based on the structural information of the facility 3. In this example, the instruction unit 20 sets the floor as an arbitrary indoor floor of the facility 3. When there are a plurality of indoor floors in the facility 3, the command unit 20 may stop the car 9 at the nearest indoor floor.

As described above, the instruction unit 20 of the management system 18 according to embodiment 2 sets the indoor floor of the facility 3 to the floor at which the user gets off the car 9 before stopping the operation of the elevator 2.

According to this configuration, since the floor from which the user gets off is an indoor floor by opening the car door 12, it is possible to prevent wind and rain from being blown into the car 9 and the hoistway 4 from the open car door 12. This can more effectively suppress damage caused by water entering the hoistway 4 or the like.

The upper floor is set in advance as the indoor floor of the facility 3.

According to this configuration, since the car 9 stands by at the indoor floor, water blown into the landing 5 by wind can be prevented from flowing into the car 9 and the hoistway 4. This can more effectively suppress damage caused by water entering the hoistway 4 or the like.

The instruction unit 20 also makes the door opening time of the elevator 2 at the outdoor floor of the facility 3 shorter than during normal operation while the evacuation function is being performed.

The travel range of the car 9 during the standby period of the upper floor may be not particularly limited. At this time, the car 9 may travel to an outdoor floor in response to a call from the user. Even in such a case, since the door opening time at the outdoor floor is short, it is possible to prevent wind and rain from blowing into the car 9 and the hoistway 4 from the open car door 12. This can more effectively suppress damage caused by water entering the hoistway 4 or the like.

Embodiment 3.

Fig. 6 is a structural diagram of an elevator system 1 according to embodiment 3.

In the management system 18, a plurality of nearby facilities 3a are preset for the facilities 3 provided with the elevators 2. The nearby facility 3a of a certain facility 3 is, for example, a facility located within a range preset for the facility 3. In this example, each of the nearby facilities 3a is provided with an elevator 2 and a remote monitoring device 15, and the remote monitoring device 15 is used for remote monitoring of the state of the elevator 2.

The management system 18 includes a vicinity information acquiring unit 26. The vicinity information acquiring unit 26 is a part for acquiring information of each vicinity facility 3a of the facility 3 with respect to the facility 3. The vicinity information acquiring unit 26 is connected to the remote monitoring device 15 of each of the vicinity facilities 3a via, for example, the communication network 16. The vicinity information obtaining unit 26 obtains, for example, information on occurrence of flooding in the vicinity facility 3a from the remote monitoring device 15 of each vicinity facility 3a. The information of occurrence of flooding in the nearby facility 3a is, for example, information of flooding detection performed by the flooding detection unit 14 provided in the hoistway 4 of the elevator 2 of the nearby facility 3a.

The command unit 20 outputs a control signal to the elevator 2 based on the information acquired by the vicinity information acquisition unit 26.

The command unit 20 is preset with a reference value of the number of facilities. The reference value of the number of facilities is a number of 2 or more. In this example, the reference value of the number of facilities is set to two facilities. When acquiring the information of occurrence of flooding from the nearby facility 3a having the reference value or more among the nearby facilities 3a of the facility 3, the command unit 20 outputs a control signal for starting the evacuation function such as standby or operation suspension of the upper floor to the elevator 2 of the facility 3. In this example, when information on occurrence of flooding is acquired from two or more nearby facilities 3a among the nearby facilities 3a of the facility 3, the instruction unit 20 causes the elevator 2 of the facility 3 to start the evacuation function.

As described above, the management system 18 according to embodiment 3 includes the vicinity information acquiring unit 26. The vicinity information acquiring unit 26 acquires information on occurrence of flooding in each of the vicinity facilities 3a preset for the facility 3. When the vicinity information acquiring unit 26 acquires information on occurrence of flooding from the vicinity facility 3a having a predetermined number of facilities or more among the plurality of vicinity facilities 3a, the instruction unit 20 causes the elevator 2 to start the evacuation function. Here, the reference value of the number of facilities is set to 2 or more in advance.

According to such a configuration, even when the forecast of the weather information system 23, which is the basis of the degree of emergency, is inaccurate, the back-off function can be started based on the information of the nearby facility 3 a. This enables the back-off function to be started more reliably when necessary. In addition, when water immersion occurs in only a single nearby facility 3a, water immersion may occur in the nearby facility 3a due to the unique conditions. In such a case, since the command unit 20 suspends the output of the control signal for starting the backoff function, it is not easy to start the backoff function if it is not necessary. Therefore, the convenience of the user is not easily impaired.

Embodiment 4.

Fig. 7 is a structural diagram of an elevator system 1 according to embodiment 4.

The management system 18 includes a learning unit 27 and an updating unit 28. The learning unit 27 is a unit that learns the relationship between the occurrence of flooding in the hoistway 4 and the degree of emergency acquired by the acquisition unit 19. The learning unit 27 learns from the history of the degree of emergency acquired by the acquisition unit 19 and the history of the occurrence of flooding in the hoistway 4. The updating unit 28 is a unit that updates the reference value in the command unit 20 based on the learning result of the learning unit 27. The updating unit 28 updates, for example, the 1 st reference value and the 2 nd reference value.

The learning unit 27 performs learning as follows, for example. The learning unit 27 generates a frequency distribution for the degree of urgency at which the flooding detection unit 14 starts to detect the flooding, based on the past history. The learning unit 27 generates a frequency distribution for the degree of urgency when the flooding detection unit 14 no longer detects flooding, based on the past history. These frequency distributions are generated as examples of the relationship between the occurrence of flooding and the degree of urgency.

The updating unit 28 updates the reference value as follows, for example. The updating unit 28 calculates a representative value of the degree of urgency from the frequency distribution of the degree of urgency at the start of detection of flooding. The representative value of the degree of urgency is, for example, an average value, a most frequent value, a median value, a lowest value, or the like of the degree of urgency. The updating unit 28 updates the 1 st reference value of the backoff function so that the backoff function such as standby or operation stop of the upper floor starts according to the degree of urgency of the calculated representative value or more. The updating unit 28 calculates a representative value of the degree of urgency from the frequency distribution of the degree of urgency when flooding is no longer detected. The updating unit 28 updates the 2 nd reference value of the backoff function so as not to cancel the backoff function such as the standby or the operation stop of the upper floor according to the degree of urgency of the calculated representative value or more.

The learning by the learning unit 27 and the updating of the reference value by the updating unit 28 may be performed periodically, for example, at a predetermined cycle, or may be performed every time a weather disaster such as the hoistway 4 is immersed.

As described above, the management system 18 according to embodiment 4 includes the learning unit 27 and the updating unit 28. The learning unit 27 learns the relationship between the occurrence of flooding in the hoistway 4 and the degree of emergency acquired by the acquisition unit 19, based on the history of the degree of emergency acquired by the acquisition unit 19 and the history of the occurrence of flooding in the hoistway 4. The updating unit 28 updates the 1 st reference value and the 2 nd reference value based on the learning result of the learning unit 27.

Depending on the surrounding terrain, the structure of the facility 3, and other conditions inherent to the facility 3, the facility 3 may be different in the ease of occurrence of flooding from the nearby facility 3 a. In contrast, since the reference value is updated based on the history of the occurrence of flooding and the history of the degree of emergency, the backoff function can be implemented based on the reference value considering the influence of the inherent condition of the facility 3. This makes it possible to reduce damage caused by flooding and ensure convenience for users in accordance with the conditions of each facility 3.

Embodiment 5.

Fig. 8 is a structural diagram of an elevator system 1 according to embodiment 5.

The management system 18 includes a facility information storage unit 25, a prediction unit 29, and a correction unit 30. The predicting unit 29 predicts that water immersion occurs in the hoistway 4. The prediction unit 29 predicts the outdoor floor of the facility 3 based on the condition of the landing 5 and weather information of the place where the facility 3 is installed. Here, the prediction unit 29 refers to the facility information storage unit 25 to obtain the condition of the landing 5 at the outdoor floor of the facility 3. The correction unit 30 corrects the degree of urgency acquired by the acquisition unit 19 based on the prediction result of the prediction unit 29.

The prediction unit 29 predicts the occurrence of flooding, for example, based on a prediction model generated as described below. The prediction model calculates the probability of occurrence of water immersion in the hoistway 4 after a predetermined time period, for example, using the weather information acquired by the acquisition unit 19 from the weather information system 23 as an input. Here, the preset time is, for example, 60 minutes. The prediction unit 29 groups, for example, weather phenomena associated with the occurrence of water immersion such as rainfall, and the like, phenomena occurring in the past according to the intensity of the association with water immersion. The strength of the relation with the immersion is calculated from weather information such as precipitation. The prediction unit 29 calculates, for each group, the proportion of the phenomenon that has occurred in the past, in which the hoistway 4 has been immersed after a predetermined time, as the probability of occurrence of the immersion in the hoistway 4 after the predetermined time. The probabilities thus calculated for each group are examples of predictive models. The prediction unit 29 determines which group the currently occurring phenomenon such as rainfall belongs to, based on the weather information acquired by the acquisition unit 19. The prediction unit 29 calculates the probability calculated for the group to which the currently occurring phenomenon belongs as the probability of occurrence of water immersion in the hoistway 4 after a time set in advance from the present.

The prediction unit 29 may use histories of a plurality of facilities 3 different from each other in generating the prediction model so that the number of sufficient phenomena can be ensured. At this time, the prediction unit 29 corrects the probability in the prediction model based on the condition of the landing 5 at the outdoor floor of the facility 3 and the weather information at the location where the facility 3 is installed. Here, the conditions of the landing 5 on the outdoor floor include, for example, the area of the landing 5, the direction in which the landing 5 is exposed outdoors, and the extent to which the landing 5 is exposed. The extent of exposure includes, for example, the area of an opening that is not provided with a roof or exposed to the outside. The weather information includes measured values or predicted values of wind speed, wind direction, and precipitation. The weather information includes information such as an alarm or notice of weather disaster prevention. For example, when the current wind is the direction in which the landing 5 of the outdoor floor is exposed, the prediction unit 29 calculates the probability of occurrence of flooding by adding or subtracting the probability in the prediction model based on the wind speed, the degree to which the landing 5 is exposed, and the like.

The correction unit 30 corrects the degree of urgency as follows, for example. When the probability of occurrence of flooding predicted by the prediction unit 29 is greater than the predetermined probability, the correction unit 30 sets the degree of urgency acquired by the acquisition unit 19 to a higher degree of urgency. Alternatively, in a case where the degree of urgency is represented by a continuous numerical value, the correction unit 30 may perform correction by adding a value corresponding to the probability predicted by the prediction unit 29 to the degree of urgency.

The command unit 20 outputs a control signal according to the degree of urgency corrected by the correction unit 30.

The prediction unit 29 may generate the prediction model by other methods. The prediction unit 29 may generate a prediction model that receives, as input, weather information of a location where the facility 3 is installed and structural information of the facility 3, and outputs a time until the occurrence of flooding. The prediction unit 29 generates a prediction model by, for example, a supervised learning method using, as learning data, weather information of a phenomenon that has occurred in the past, structural information of the facility 3, and a set of times until flooding occurs in the facility 3 due to the phenomenon. The prediction unit 29 may generate a prediction model by another machine learning method or the like. At this time, for example, when the time period from the occurrence of flooding predicted by the predicting unit 29 to the occurrence of flooding is shorter than a predetermined time period, the correcting unit 30 sets the degree of urgency acquired by the acquiring unit 19 to a higher degree of urgency.

The prediction unit 29 may predict the occurrence of the water immersion in the hoistway 4 using information of an abnormality occurring in the nearby facility 3 a.

As described above, the management system 18 according to embodiment 5 includes the prediction unit 29 and the correction unit 30. The prediction unit 29 predicts the occurrence of the water immersion in the hoistway 4 based on the condition of the landing 5 on the outdoor floor of the facility 3 and the weather information of the place where the facility 3 is installed. The correction unit 30 corrects the degree of urgency acquired by the acquisition unit 19 based on the prediction result of the prediction unit 29.

According to this configuration, since the emergency degree is corrected based on the prediction of the condition unique to the facility 3, such as the condition of the landing 5 taking into account the outdoor floor of the facility 3, the evacuation function can be implemented based on the emergency degree taking into account the influence of the condition unique to the facility 3. This makes it possible to reduce damage caused by flooding and ensure convenience for users in accordance with the conditions of each facility 3.

Embodiment 6.

Fig. 9 is a structural diagram of an elevator system 1 according to embodiment 6.

The elevator 2 is provided with an imaging device 32. The imaging device 32 is a device that photographs the hoistway 4. The imaging device 32 is disposed in the lower part of the car 9. The image pickup device 32 picks up, for example, a pit. The images taken by the camera device 32 are collected in the management system 18, for example, via the control panel 11 and the remote monitoring device 15.

The elevator 2 is provided with a swinging portion 33. The swinging portion 33 is a portion that performs an operation of swinging the water surface when the hoistway 4 is immersed. The swinging portion 33 is disposed at the lower portion of the car 9. The swinging portion 33 drops liquid, blows air, radiates sound, or the like, for example, to the lower side of the car 9. When the hoistway 4 is immersed, the water surface fluctuates due to this operation. The control system 18 operates the swinging portion 33 at a preset timing of detecting water immersion, for example. The control system 18 operates the swinging unit 33, for example, by a control signal from the command unit 20.

The management system 18 includes an image processing unit 31. The image processing unit 31 detects the water immersion in the hoistway 4 from the image captured by the imaging device 32. The image processing unit 31 detects the water penetration of the hoistway 4 from an image captured by the imaging device 32 after the operation of the swinging unit 33 that swings the water surface when the hoistway 4 is immersed, for example, as follows. When the hoistway 4 is immersed, the imaging device 32 captures the water surface that fluctuates due to the operation of the swinging portion 33. The image processing unit 31 detects the water surface waves and the like to detect the water immersion of the hoistway 4. On the other hand, when the hoistway 4 is not immersed, there is no water surface in the range captured by the imaging device 32, and therefore, even if the swinging portion 33 is operated, the image processing portion 31 does not detect waves or the like. Therefore, the image processing unit 31 does not detect the hoistway 4 immersed in water.

When the image processing unit 31 detects a water bath, the command unit 20 outputs a control signal to the control panel 11 of the elevator 2, the control signal being suppressed so that the car 9 does not travel to the water bath.

The management system 18 may use equipment for operating the elevator 2 as the swinging portion 33. The management system 18 may use, for example, a not-shown governor rope or a tensioning sheave thereof disposed in the pit as the swinging portion 33. These devices move in the pit along with the travel of the car 9. Therefore, when the hoistway 4 is immersed, the water surface fluctuates by these devices when the car 9 is traveling. Therefore, the management system 18 may drive the car 9 upward by a control signal or the like of the command unit 20 as an operation of fluctuating the water surface when the hoistway 4 is immersed in water, before the image processing by the image processing unit 31.

In addition, the image processing unit 31 may detect the flooding of the hoistway 4 by ripple detection based on the water flowing into the hoistway 4.

As described above, the management system 18 according to embodiment 6 includes the image processing unit 31. The image processing unit 31 detects the water immersion in the hoistway 4 from an image of the hoistway 4 captured by an imaging device 32 provided at the lower portion of the car 9. When the image processing unit 31 detects that the hoistway 4 is immersed, the command unit 20 causes the elevator 2 to suppress the car 9 from traveling to a portion where the hoistway 4 is immersed.

According to this configuration, even in the elevator 2 in which the flooding detection unit 14 is not provided in the hoistway 4 or in the elevator 2 in which the flooding detection unit 14 is provided at a high position, flooding of the pit can be detected from the image. This can reduce damage to the elevator 2 caused by flooding or the like more effectively.

The elevator system 1 further includes a swinging portion 33. The swinging portion 33 performs an operation of swinging the water surface when the hoistway 4 is immersed. The image processing unit 31 detects the flooding of the hoistway 4 from the image of the hoistway 4 captured after the operation of the swinging unit 33.

According to such a configuration, even when the inflow of water into the hoistway 4 has stopped, the image processing unit 31 can more reliably detect the flooding of the hoistway 4.

Embodiment 7.

Fig. 10 is a structural diagram of an elevator system 1 according to embodiment 7.

In this example, the water immersion detection unit 14 is a rear mounting device additionally provided to the existing elevator 2. At this time, the flooding detection unit 14 is not connected to the control board 11. The flooding detection unit 14 is connected to a remote monitoring device 15. The flooding detection unit 14 is connected to a general switch or the like of the remote monitoring device 15.

As described above, the elevator system 1 according to embodiment 7 includes the management system 18, the flooding detection unit 14, and the remote monitoring device 15. The flooding detection unit 14 is provided in the hoistway 4. The flooding detection unit 14 is not connected to the control panel 11. The flooding detection unit 14 detects flooding of the hoistway 4. The remote monitoring device 15 is connected to the flooding detection unit 14 so as to be able to receive detection information from the flooding detection unit 14. The remote monitoring device 15 supplies information on the state of the elevator 2 including the detection information from the flooding detection unit 14 to the management system 18.

According to this configuration, since the detection information of the flooding detection unit 14 is supplied to the management system 18 without passing through the control panel 11, the flooding detection unit 14 can be introduced without requiring the construction of changing the specification of the elevator 2 itself including the control panel 11. Thereby, the management system 18 can be applied to more kinds of elevators 2.
