[0007] According to the elevator monitoring system and elevator monitoring method described herein, in the event of a tsunami caused by a rise in atmospheric pressure, the elevator can perform flood evacuation operations. [Brief explanation of the drawing]

[0008] [Figure 1] This is a block diagram showing the elevator monitoring system according to Embodiment 1. [Figure 2] Figure 1 is a diagram showing the configuration of the elevator monitoring system. [Figure 3] This graph shows how atmospheric pressure temporarily rises due to the air shock waves generated by a large-scale volcanic eruption. [Figure 4] This is a flowchart showing the processing of the elevator monitoring system according to Embodiment 1. [Modes for carrying out the invention]

[0009] Figure 1 is a block diagram showing an elevator monitoring system according to Embodiment 1. Figure 2 is a configuration diagram showing the elevator monitoring system of Figure 1. The elevator monitoring system according to Embodiment 1 comprises an elevator 1, a pressure information acquisition device 2, a monitoring device 3, and an information center 4.

[0010] Elevator 1 comprises an elevator control panel 101, an elevator hoisting machine 102, an elevator car 103, an in-car speaker 104, and an in-car display 105.

[0011] The elevator control panel 101 controls the drive of the elevator hoisting machine 102. The elevator car 103 moves up and down in a hoistway (not shown) by the drive of the elevator hoisting machine 102. An in-car speaker 104 and an in-car display 105 are installed in the elevator car 103.

[0012] The elevator control panel 101 receives flood evacuation operation commands, which will be described later, from the monitoring device 3. When a flood evacuation operation command is received by the elevator control panel 101, the elevator control panel 101 controls the elevator hoisting machine 102 so that elevator 1 performs flood evacuation operation.

[0013] In the flood evacuation operation of elevator 1, the elevator control panel 101 first determines whether or not there are passengers in the elevator car 103.

[0014] If the elevator control panel 101 determines that there are passengers in elevator car 103, the elevator control panel 101 moves elevator car 103 to a pre-set evacuation floor and then opens the entrance to elevator car 103. This allows passengers in elevator car 103 to disembark at the evacuation floor. After the passengers in elevator car 103 have disembarked at the evacuation floor, the elevator control panel 101 moves elevator car 103 to the top floor and puts elevator 1 into a deactivation state. Examples of evacuation floors include the ground floor, the nearest floor, and the top floor.

[0015] On the other hand, when the elevator control panel 101 determines that there are no passengers in the elevator car 103, the elevator control panel 101 moves the elevator car 103 to the top floor, and then places the elevator 1 in a dormant state.

[0016] When the elevator control panel 101 moves the elevator car 103 to the evacuation floor, the in-car speaker 104 emits a voice indicating evacuation guidance, and the in-car display 105 displays an image indicating evacuation guidance. The in-car speaker 104 and the in-car display 105 are controlled by an operation control command unit 303, which will be described later in the monitoring device 3. The in-car speaker 104 and the in-car display 105 may be controlled by the elevator control panel 101.

[0017] The atmospheric pressure information acquisition device 2 is installed in the building where the elevator 1 is installed. The atmospheric pressure information acquisition device 2 includes a barometer (not shown). The barometer of the atmospheric pressure information acquisition device 2 periodically measures the atmospheric pressure in the area where the building with the elevator 1 is located. As the barometer of the atmospheric pressure information acquisition device 2 measures the atmospheric pressure, the atmospheric pressure information acquisition device 2 periodically acquires atmospheric pressure information. The atmospheric pressure information acquired by the atmospheric pressure information acquisition device 2 is output from the atmospheric pressure information acquisition device 2 and input to the monitoring device 3.

[0018] The monitoring device 3 is installed in the building where the elevator 1 is installed. The monitoring device 3 includes an atmospheric pressure determination processing unit 301, an area determination processing unit 302, and an operation control command unit 303.

[0019] When a large-scale eruption occurs, the atmospheric pressure rises temporarily due to the air shock wave generated by the eruption, and a tsunami is generated. Figure 3 is a graph showing how the atmospheric pressure rises temporarily due to the air shock wave generated by the eruption when a large-scale eruption occurs. In Figure 3, the vertical axis represents atmospheric pressure, and the horizontal axis represents time. When a large-scale eruption that can generate a tsunami occurs, the atmospheric pressure rises by approximately 0.8 to 1.5 hPa per hour, as shown in Figure 3.

[0020] In the atmospheric pressure determination processing unit 301, a threshold T used for determining whether or not the elevator 1 performs a submergence evacuation operation is stored in advance. The threshold T stored in the atmospheric pressure determination processing unit 301 corresponds to an increase amount A of atmospheric pressure per unit time such that a tsunami is generated.

[0021] The atmospheric pressure information output from the atmospheric pressure information acquisition device 2 is input to the atmospheric pressure determination processing unit 301. Using the threshold T pre-stored in the atmospheric pressure determination processing unit 301 and the atmospheric pressure information input to the atmospheric pressure determination processing unit 301, the atmospheric pressure determination processing unit 301 determines whether or not the increase amount A of atmospheric pressure per unit time exceeds the preset threshold T.

[0022] An area predicted to be flooded by the arrival of a tsunami is defined as a flood predicted area. The flood predicted area is determined by the altitude above sea level of the area and the distance from the coast and rivers to the area. In the area determination processing unit 302, the position information of the building where the elevator 1 is installed and the position information of the flood predicted area are stored in advance.

[0023] The area determination processing unit 302 uses the position information of the building where the elevator 1 is installed and the position information of the flood predicted area to determine whether or not the area where the elevator 1 is installed is included in the flood predicted area.

[0024] The determination result of the atmospheric pressure determination processing unit 301 and the determination result of the area determination processing unit 302 are input to the operation control command unit 303. When the atmospheric pressure determination processing unit 301 determines that the increase amount A of atmospheric pressure per unit time exceeds the threshold T, and the area determination processing unit 302 determines that the area where the elevator 1 is installed is included in the flood predicted area, the operation control command unit 303 outputs a submergence evacuation operation command.

[0025] The flood avoidance operation command output from the operation control command unit 303 is input to the elevator control panel 101. When the flood avoidance operation command is input to the elevator control panel 101, the elevator control panel 101 controls the elevator hoisting machine 102 so that elevator 1 performs flood avoidance operation.

[0026] Furthermore, the flood evacuation operation command output from the operation control command unit 303 is input to the information center 4 along with information identifying elevator 1. The information center 4 records that elevator 1 is performing flood evacuation operation.

[0027] Next, the elevator monitoring method in the elevator monitoring system according to Embodiment 1 will be described. Figure 4 is a flowchart showing the processing of the elevator monitoring system according to Embodiment 1. First, in step S101, a pressure determination process is performed. In the pressure determination process, the pressure determination processing unit 301 determines whether the increase in pressure A per unit time exceeds the threshold T. The pressure determination process is performed each time pressure information is input to the pressure determination processing unit 301.

[0028] In step S101, if the pressure determination processing unit 301 determines that the increase in pressure A per unit time does not exceed the threshold T, the elevator monitoring system according to Embodiment 1 repeats step S101.

[0029] On the other hand, if the pressure determination processing unit 301 determines in step S101 that the increase in pressure per unit time A exceeds the threshold T, the elevator monitoring system according to Embodiment 1 proceeds to step S102.

[0030] In step S102, a regional determination process is performed. In the regional determination process, the regional determination processing unit 302 determines whether or not the area where the elevator 1 is installed is included in the flood prediction area.

[0031] In step S102, if the area determination processing unit 302 determines that the area where elevator 1 is installed is not included in the flood prediction area, the processing of the elevator monitoring system according to Embodiment 1 is terminated.

[0032] On the other hand, if the area determination processing unit 302 determines in step S102 that the area where elevator 1 is installed is included in the flood prediction area, the processing of the elevator monitoring system according to Embodiment 1 proceeds to step S103.

[0033] In step S103, the operation control command process is performed. In the operation control command process, the operation control command unit 303 outputs a flood evacuation operation command, and the outputted flood evacuation operation command is input to the elevator control panel 101. After that, the processing of the elevator monitoring system according to Embodiment 1 proceeds to step S104.

[0034] In step S104, the flood evacuation operation process is performed. In the flood evacuation operation process, the elevator control panel 101 first determines whether or not there are passengers in the elevator car 103.

[0035] In step S104, if the elevator control panel 101 determines that there are passengers in the elevator car 103, the elevator control panel 101 moves the elevator car 103 to a pre-set evacuation floor and then opens the door to the elevator car 103. This allows the passengers in the elevator car 103 to disembark at the evacuation floor. At this time, the operation control command unit 303 controls the in-car speaker 104 and the in-car display 105, so that the in-car speaker 104 emits an audio message indicating evacuation guidance and the in-car display 105 displays an image indicating evacuation guidance.

[0036] After the passengers in elevator car 103 disembark at the evacuation floor, the elevator control panel 101 moves elevator car 103 to the top floor and puts elevator 1 into a deactivated state.

[0037] On the other hand, if the elevator control panel 101 determines in step S104 that there are no passengers in the elevator car 103, the elevator control panel 101 moves the elevator car 103 to the top floor and then puts the elevator 1 into a paused state. With this, the processing of the elevator monitoring system according to Embodiment 1 is completed.

[0038] As described above, the elevator monitoring system according to Embodiment 1 comprises a pressure determination processing unit 301 and an operation control command unit 303. The pressure determination processing unit 301 determines whether the increase in pressure per unit time A exceeds a threshold T. Based on the determination result of the pressure determination processing unit 301, the operation control command unit 303 outputs a flood evacuation operation command to the elevator 1. With this configuration, the elevator 1 can perform flood evacuation operation in the event of a tsunami caused by a rise in pressure.

[0039] Furthermore, the elevator monitoring system according to Embodiment 1 further includes a regional determination processing unit 302. The regional determination processing unit 302 determines whether the area where the elevator 1 is installed is included in the flood prediction area. The operation control command unit 303 outputs a flood evacuation operation command to the elevator 1 based on the determination result of the atmospheric pressure determination processing unit 301 and the determination result of the regional determination processing unit 302. With this configuration, in the event of a tsunami caused by a rise in atmospheric pressure, the elevator 1 can perform flood evacuation operation in response to whether the area where the elevator 1 is installed is included in the flood prediction area. As a result, the elevator 1 can perform flood evacuation operation at a more appropriate timing.

[0040] Furthermore, the elevator monitoring method according to Embodiment 1 includes a pressure determination process and an operation control command process. In the pressure determination process, it is determined whether the increase in pressure per unit time A exceeds a threshold T. The operation control command process is performed after the pressure determination process. In the operation control command process, a flood evacuation operation command is output to the elevator 1 based on the determination result of the pressure determination process. With this configuration, the elevator 1 can perform flood evacuation operation when a tsunami occurs due to a rise in pressure.

[0041] Furthermore, the elevator monitoring method according to Embodiment 1 further includes a region determination process. In the region determination process, it is determined whether or not the area where the elevator 1 is installed is included in the flood prediction area. After the atmospheric pressure determination process and the region determination process, the operation control command process outputs a flood evacuation operation command to the elevator 1 based on the determination results of the atmospheric pressure determination process and the determination results of the region determination process. With this configuration, in the event of a tsunami caused by a rise in atmospheric pressure, the elevator 1 can perform flood evacuation operation in response to whether or not the area where the elevator 1 is installed is included in the flood prediction area. As a result, the elevator 1 can perform flood evacuation operation at a more appropriate timing.

[0042] In the first embodiment of the elevator monitoring system, a configuration was described in which the barometric pressure information acquisition device 2 is installed in the building where the elevator 1 is located. However, the elevator monitoring system may also be configured in which the barometric pressure information acquisition device 2 is installed outside the building where the elevator 1 is located. In this case, for example, the barometric pressure information acquisition device 2 may be installed in the information center 4.

[0043] Furthermore, in the elevator monitoring system according to Embodiment 1, the barometric pressure information acquisition device 2 is equipped with a barometer, and the barometric pressure information acquisition device 2 acquires barometric pressure information by measuring the barometric pressure. However, the elevator monitoring system may also be configured such that barometric pressure information is input from the information center 4 to the barometric pressure information acquisition device 2.

[0044] Furthermore, the elevator monitoring system according to Embodiment 1 was described in a configuration that includes one elevator 1. However, the elevator monitoring system may also be configured to include multiple elevators 1. In this case, the elevator monitoring system may be configured such that a barometric pressure information acquisition device 2 with a barometer is installed only in the building where one of the multiple elevators 1 is installed. The barometric pressure information acquired by the barometric pressure information acquisition device 2 with a barometer is output from the barometric pressure information acquisition device 2 with a barometer and input to the information center 4. The barometric pressure information input to the information center 4 is output from the information center 4 and input to a barometric pressure information acquisition device 2 without a barometer. As a result, even if the configuration is such that a barometric pressure information acquisition device 2 with a barometer is installed only in the building where one of the multiple elevators 1 is installed, each of the multiple elevators 1's barometric pressure information acquisition devices 2 can acquire barometric pressure information.

[0045] Furthermore, in the elevator monitoring system according to Embodiment 1, a configuration was described in which the monitoring device 3 is installed in the building where the elevator 1 is located. However, the elevator monitoring system may also be configured in which the monitoring device 3 is installed outside the building where the elevator 1 is located. In this case, for example, the elevator monitoring system may be configured in which the monitoring device 3 is installed in the information center 4.

[0046] Furthermore, in the elevator monitoring system according to Embodiment 1, a configuration was described in which one threshold T corresponding to the amount of increase in atmospheric pressure per unit time A that causes a tsunami is stored in the atmospheric pressure determination processing unit 301. However, the elevator monitoring system may also be configured such that multiple thresholds T are pre-stored in the atmospheric pressure determination processing unit 301, and each of the multiple thresholds T pre-stored in the atmospheric pressure determination processing unit 301 corresponds to the expected height of the tsunami. In this case, the area determination processing unit 302 may store multiple inundation prediction areas corresponding to the predicted height of the tsunami. In other words, the inundation prediction areas may change in response to the predicted height of the tsunami.

[0047] Information on the largest threshold T that the increase in atmospheric pressure per unit time A exceeds among multiple thresholds T is output from the atmospheric pressure determination processing unit 301 and input to the area determination processing unit 302. The area determination processing unit 302 uses the location information of the flood prediction area corresponding to the threshold T input to the area determination processing unit 302 among multiple flood prediction areas to determine whether the area where elevator 1 is installed is included in the flood prediction area. In this way, the area determination processing unit 302 can determine whether the area where elevator 1 is installed is included in the flood prediction area in accordance with the expected tsunami height.

[0048] The elevator monitoring system is not limited to a configuration in which threshold T information is output from the pressure determination processing unit 301 and input to the area determination processing unit 302. For example, the elevator monitoring system may be configured in which pressure information output from the pressure information acquisition device 2 is input to the area determination processing unit 302. In this case, the area determination processing unit 302 uses the location information of the flood prediction area corresponding to the amount of pressure increase A per unit time among a plurality of flood prediction areas to determine whether the area where the elevator 1 is installed is included in the flood prediction area.

[0049] Furthermore, the elevator monitoring system according to Embodiment 1 was described in which the location information of the building where elevator 1 is installed and the location information of the flood prediction area are pre-stored in the area determination processing unit 302. However, the elevator monitoring system may also be configured in which the location information of the building where elevator 1 is installed and the location information of the flood prediction area are pre-stored in the information center 4. In this case, the area determination processing unit 302 transmits information that identifies elevator 1 to the information center 4. The information center 4, in response to the information that identifies elevator 1 transmitted to the information center 4, transmits the location information of the building where elevator 1 is installed and the location information of the flood prediction area to the area determination processing unit 302.

[0050] Although a preferred embodiment 1 of the elevator monitoring system has been described above, the system is not limited to the elevator monitoring system according to embodiment 1 described above. Various modifications and transformations can be made to the elevator monitoring system according to embodiment 1 described above without departing from the scope of the claims.
