Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, regarding the method of canceling the flood evacuation operation, it is common to set a time limit until cancellation at the time of setting and automatically cancel it after the specified time limit has elapsed. However, after a flood or typhoon, rainwater may accumulate on the elevator hall side. In this case, if normal operation is started immediately after canceling the flood evacuation operation, there is a risk that the rainwater accumulated on the elevator hall side will run along the door sill and fall onto the car. Control devices such as the opening and closing device of the car door are installed on the car, and the rainwater that has fallen onto the car can cause these control devices to malfunction.

[0005] Therefore, an object of the present invention is to provide an elevator control system and an elevator control method capable of reducing water damage to the car.

Means for Solving the Problems

[0006] In order to solve the above problems, for example, the configuration described in the claims is adopted. Although this application includes a plurality of means for solving the above problems, if an example is given, in an elevator control system including a flood evacuation operation control unit that controls the flood evacuation operation of the elevator and a flood evacuation operation cancellation management unit that manages the cancellation of the flood evacuation operation, when it is determined in the flood evacuation operation cancellation management unit that the flood evacuation operation is to be canceled, the car of the elevator is sequentially landed from the upper floor to the lower floor, and at each floor where the landing is made, a drainage operation control unit that performs a drainage operation of repeatedly opening and closing the car door of the car is provided.

Effects of the Invention

[0007] According to the present invention, it is possible to provide an elevator control system and an elevator control method that can more reliably prevent water damage to the car.

Modes for Carrying Out the Invention

[0009] Hereinafter, each embodiment to which the present invention is applied will be described in detail with reference to the drawings. In each of the embodiments described below, the same reference numerals are given to the same components, and redundant descriptions are omitted.

[0010] ≪First Embodiment≫ <Elevator Control System> FIG. 1 is a configuration diagram of an elevator control system 100 according to the first embodiment. The elevator control system 100 shown in FIG. 1 is a system for controlling the operation of a plurality of elevators 100a, and has a function of suppressing waterlogging damage to the elevators 100a caused by guerrilla heavy rain or typhoons. The elevators 100a controlled by the elevator control system 100 are a plurality of elevators 100a installed in the same building or different buildings. Here, only one elevator 100a is illustrated.

[0011] Each elevator 100a includes a car 1, a car door 2 provided on the car 1, a door opening / closing device 3 that controls the opening and closing of the car door 2, interior lighting 4 in the car, an interior display unit 5, and an interior speaker 6. Each elevator 100a also includes a landing door 7 provided on each floor of the travel path along which the car 1 travels, a landing operation panel 8 provided on each floor, and an elevator control device 9 that controls the travel of the car 1 and the opening and closing of the car door 2.

[0012] And an elevator control system 100 for controlling the operation of such an elevator 100a includes an elevator control device 9 that the elevator 100a has, and a control center 11 connected to the elevator control device 9 via the Internet network 10. The elevator control system 100 also includes a precipitation information management server 12 connected to the Internet network 10.

[0013] These elevator control device 9, control center 11, and precipitation information management server 12 are each constituted by a computer. A computer includes hardware used as a so-called computer, such as a CPU (Central Processing Unit), a RAM (Random Access Memory), a non-volatile storage unit such as a ROM (Read Only Memory), and further includes a network interface.

[0014] Among these, the elevator control device 9 has functional units such as a control center communication unit 9a, a flood evacuation operation mode management unit 9b, a flood evacuation operation cancellation management unit 9c, a flood evacuation operation cancellation mode management unit 9d, a flood evacuation operation control unit 9e, a drainage operation control unit 9f, a passenger boarding inhibition control unit 9g during drainage operation, a door motor torque detection unit 9h, and a door motor torque control unit 9i during drainage operation. The functions of these functional units will be described in the following elevator control method.

[0015] In addition, the control center 11 includes functional units such as an Internet network communication unit 11a, a flood evacuation operation setting unit 11b, a flood evacuation operation mode management unit 11c, and a flood evacuation cancellation mode determination unit 11d. The functions of these functional units will be described in the following elevator control method.

[0016] The precipitation information management server 12 is an external server that handles meteorological information, such as a computer owned by the Japan Meteorological Agency or other weather forecasting companies.

[0017] <Elevator Control Method> Next, an elevator control method implemented by the above-described elevator control system 100 will be described.

[0018] FIG. 2 is a flowchart (Part 1) showing the elevator control method of the first embodiment, and shows the procedure of elevator control implemented according to the programs of the respective parts of the elevator control system 100 described with reference to FIG. 1. This flow is automatically started based on the precipitation amounts in each region acquired by the control center 11 from the precipitation information management server 12. In this case, for example, it is started when the control center 11 acquires a forecast that the precipitation amount per hour exceeds a predetermined value (for example, 30 mm) from the precipitation information management server 12.

[0019] Hereinafter, the procedure of the elevator control method will be described with reference to FIGS. 1 and other figures along the flowchart of FIG. 2.

[0020] First, in step S101, the flood evacuation operation mode management unit 9b of each elevator 100a determines whether or not there is a setting for flood evacuation operation. At this time, the flood evacuation operation mode management unit 9b makes this determination by referring to the flood evacuation operation setting unit 11b of the control center 11 because it has received a forecast of the occurrence of flood damage from the control center 11. The flood evacuation operation setting unit 11b has set the flood evacuation operation remotely for all elevators 100a managed by this control center 11 before the occurrence of flood and water disasters, and is assumed to have information regarding the presence or absence of the setting of the flood evacuation operation.

[0021] For the elevator 100a determined to have a setting (YES), the flood evacuation operation mode management unit 9b proceeds to the next step S102. On the other hand, for the elevator 100a determined to have no setting (NO), the process is terminated. Note that the flood evacuation operation mode management unit 9b of each elevator 100a may have information on whether there is a setting for the flood evacuation operation.

[0022] In step S102, the flood evacuation operation control unit 9e of each elevator 100a that has advanced from step S101 determines whether the flood evacuation operation mode is set to the "operation pause" mode. At this time, the flood evacuation operation control unit 9e makes this determination by referring to the flood evacuation operation mode management unit 11c of the control center 11. The flood evacuation operation mode management unit 11c shall have the setting information of the pre-set flood evacuation operation mode for all elevators 100a for which the flood evacuation operation is set. Note that the flood evacuation operation control unit 9e of each elevator 100a may have the setting information of the flood evacuation operation mode.

[0023] If the flood evacuation operation control unit 9e determines that it is set to the "operation pause" mode (YES), it proceeds to step S103. On the other hand, if it determines that it is not set (NO), it proceeds to step S104.

[0024] In step S103, the flood evacuation operation control unit 9e moves the car 1 to the top floor, pauses the operation of the elevator 100a, and proceeds to step S106.

[0025] On the other hand, step S104 is the step that proceeds after determining in step S102 that the flood evacuation operation mode is not set to the "operation pause" mode (NO). In this case, it is assumed that the flood evacuation operation mode is set to the "standby floor setting" mode. The "standby floor setting" mode is an operation mode in which, when there is no call, the car is evacuated to a predetermined reference floor (typically the top floor) and the operation continues.

[0026] In this step S104, the flooding evacuation operation control unit 9e determines whether the elevator 100a is unused. Whether the elevator 100a is unused is determined, for example, by the fact that there are no passengers in the car 1 or there is no call setting. If the flooding evacuation operation control unit 9e determines that the elevator 100a is unused (YES), it proceeds to step S105. On the contrary, if the flooding evacuation operation control unit 9e determines that there are passengers in the car 1 (or there is a call setting) and the elevator 100a is not unused (NO), it continues the operation of the currently used elevator 100a and proceeds to step S106.

[0027] On the other hand, in step S105, since the elevator 100a is unused, the flooding evacuation operation control unit 9e moves the car 1 to the top floor and proceeds to step S106.

[0028] In step S106, the flooding evacuation operation cancellation management unit 9c determines whether the time limit for the flooding evacuation operation setting has elapsed. Here, the time limit for the flooding evacuation operation setting is the time from the start of the flooding evacuation operation setting to the cancellation of the flooding evacuation operation, which is a preset time. If the flooding evacuation operation cancellation management unit 9c determines that it has elapsed (YES), it proceeds to the next step S107. If it determines that it has not elapsed (NO), it returns to step S102.

[0029] In step S107, the flooding evacuation operation cancellation mode management unit 9d determines whether the cancellation mode of the flooding evacuation operation is "cancelled after drainage operation". At this time, the flooding evacuation operation cancellation mode management unit 9d refers to the flooding evacuation cancellation mode determination unit 11d of the control center 11 to perform this determination. It is assumed that the flooding evacuation cancellation mode determination unit 11d has the setting information of the preset flooding evacuation cancellation mode for all elevators 100a for which the flooding evacuation operation is set. Note that the flooding evacuation operation cancellation mode management unit 9d of each elevator 100a may have the setting information of the flooding evacuation cancellation mode.

[0030] When the flooding evacuation operation cancellation mode management unit 9d determines that the cancellation mode of the flooding evacuation operation is "cancelled after drainage operation" (YES), it proceeds to step S108. On the other hand, when it determines that it is not "cancelled after drainage operation" (NO), it proceeds to step S109.

[0031] In step S108, the drainage operation control unit 9f performs a drainage operation. FIG. 3 is a flowchart (part 2) showing the elevator control method of the first embodiment, and shows the procedure of the drainage operation performed by the elevator control device 9. Hereinafter, the procedure of the drainage operation will be described along the flowchart of FIG. 3.

[0032] In step S201, the drainage operation control unit 9f determines whether the current car position of the car 1 is the top floor. If it determines that it is the top floor (YES), it proceeds to step S203, and if it determines that it is not the top floor (NO), it proceeds to step S202.

[0033] In step S202, the drainage operation control unit 9f moves the car 1 to the top floor and proceeds to step S203.

[0034] In step S203, the drainage operation control unit 9f starts the drainage operation.

[0035] In the next step S204, the passenger boarding inhibition control unit 9g during drainage operation performs a process of inhibiting passenger boarding into the car 1. The inhibition process performed by the passenger boarding inhibition control unit 9g during drainage operation is, for example, disabling the operation of the hall operation panel 8, turning off the car interior lighting 4, displaying a message on the car interior display unit 5, and giving a warning announcement by the car interior speaker 6.

[0036] FIG. 4 is a diagram showing a display example of the car interior display unit 5 for suppressing passenger boarding during drainage operation. As shown in FIG. 4, during the drainage operation, the passenger boarding suppression control unit 9g causes the car interior display unit 5 to display that the drainage operation is currently in progress and a warning prompting getting off as a passenger boarding suppression process. Thereby, boarding of passengers into the car 1 during the drainage operation is suppressed.

[0037] Thereafter, in step S205, the drainage operation control unit 9f performs an operation of opening and closing the car door 2 a plurality of times. The number of times of opening and closing the car door 2 may be, for example, a preset number of times or a number determined experimentally (for example, 5 times). By this operation, on the floor where the car 1 has landed, the hall door 7 connected to the car door 2 is opened and closed, and rainwater accumulated on the elevator hall side is dropped from the door sill of the hall door 7 below the car 1 to forcibly drain the water.

[0038] In step S206, the door motor torque detection unit 9h determines whether the door motor torque feedback value during the opening and closing operation of the car door 2 in step S205 is equal to or less than the normal value. Here, the normal value is defined as the value when the car door 2 is normally opened and closed, and may have a certain range. Also, the door motor torque feedback value may be the value at the last opening and closing operation among a plurality of opening and closing operations, or the average value of a plurality of times.

[0039] When the door motor torque detection unit 9h determines that the door motor torque feedback value is equal to or less than the normal value (YES), it proceeds to step S208. On the other hand, when it is determined that the door motor torque feedback value exceeds the normal value range and is not less than the normal value (NO), it is considered that, for example, foreign matter carried by rainwater has accumulated on the door sill. Therefore, it proceeds to step S207.

[0040] In step S207, during the drainage operation, the car door motor torque control unit 9i increases the car door motor torque command value and instructs the car door opening / closing device 3 to perform multiple opening / closing operations of the car door 2 again. The number of opening / closing operations of the car door 2 here may be, for example, a preset number or a number determined experimentally. Similarly, the increase range of the car door motor torque command value is the same.

[0041] By the opening / closing operation of the car door 2 here, the foreign matter deposited on the door sill by rainwater is pushed out from the door sill. This eliminates the failure of the car door opening / closing due to the clogging of foreign matter in the door sill.

[0042] After the above, the car door motor torque command value is returned to the original value and the process proceeds to step S208. Note that in this step 207, after the car door motor torque control unit 9i increases the car door motor torque command value during the drainage operation, it may also return to step S205. In this case, in step S206, the opening / closing of the car door 2 is repeated until the car door motor torque feedback value becomes equal to or less than the normal value.

[0043] In step S208, the drainage operation control unit 9f determines whether the current car position is the lowest floor. If it is determined that it is the lowest floor (YES), the process proceeds to step S211. If it is determined that it is not the lowest floor (NO), the process proceeds to step S209.

[0044] In step S209, after the opening / closing operation of the car door 2 in step S205 or step S207, the drainage operation control unit 9f makes the car 1 wait for a certain period of time. The certain period of time here is a preset time, which is sufficient for the rainwater forcibly drained from the door sill of the hall door 7 to flow downward on the floor where the car 1 is stopped. Then the process proceeds to step S210.

[0045] In step S210, the drainage operation control unit 9f moves the car to a floor below the first floor and returns to step S205.

[0046] On the one hand, in step S211, the drainage operation control unit 9f moves the car 1 at the lowest floor to the top floor and proceeds to step S212.

[0047] In step S212, the passenger boarding suppression control unit 9g during drainage operation releases the passenger boarding suppression process performed in step S204 and ends the drainage operation process. Thereafter, it proceeds to step S109 of the flowchart in FIG. 2.

[0048] Returning to FIG. 2, in step S109, the flooding evacuation operation control unit 9e releases the flooding evacuation operation and returns to the normal elevator operation service. Thereby, the process of the flooding evacuation operation is ended.

[0049] <Effect of the First Embodiment> According to the first embodiment described above, before releasing the flooding evacuation operation and returning to normal operation, by performing a drainage operation of opening and closing the car door 2 on each floor where it has landed in order from the top floor downward, the rainwater accumulated on the elevator hall side can be forcibly drained from the door sill of the hall door 7. Thereby, when the flooding operation is released and the normal operation is resumed, it is possible to prevent the rainwater accumulated on the elevator hall side from falling on the upper part of the car 1. Thereby, it is possible to prevent failures caused by flooding of the equipment installed on the upper part of the car 1.

[0050] In the first embodiment described above, as described in step S107 (see FIG. 2), the flooding evacuation operation release mode management unit 9d is configured to perform the drainage operation shown in FIG. 3 when it is determined as "release after drainage operation" based on the preset flooding evacuation operation release mode. However, the control center 11 may automatically change the flooding evacuation operation release mode of each elevator 100a from normal release to "release after drainage operation" based on the information from the precipitation information management server 12.

[0051] In this case, when the control center 11 obtains from the precipitation information management server 12 a forecast that the precipitation per hour exceeds a certain value (for example, 30 mm), the control center 11 automatically changes the flood evacuation operation cancellation mode of the elevator 100a in the forecast area from the normal cancellation to "cancellation after drainage operation". Then, the flood evacuation cancellation mode determination unit 11d of the control center 11 is caused to hold this change by overwriting. As a result, the flood evacuation operation cancellation mode of the elevator 100a is automatically changed from the normal cancellation to "cancellation after drainage operation" based on the precipitation in that area. Note that the predetermined value of the precipitation for automatically changing the flood evacuation operation cancellation mode from the normal cancellation to "cancellation after drainage operation" is a threshold value set in advance in the control center 11.

[0052] ≪Second Embodiment≫ <Elevator Control Device> FIG. 5 is a configuration diagram of the elevator control system 200 according to the second embodiment. The elevator control system 200 according to the second embodiment shown in FIG. 5 is obtained by adding functional units to the elevator control device 9 and the control center 11 of the elevator control system of the first embodiment. These control center 11 and elevator control device 9 are connected to the precipitation / wind volume information management server 12'. Further, the elevator control system 200 additionally includes a building warning device 13.

[0053] The functional unit added to the elevator control device 9 is the non-stop floor setting processing unit 9j. The functional units added to the control center 11 are the building warning device abnormality management unit 11e, the monitored elevator installation information management unit 11f, the adjacent elevator identification unit 11g for detecting full water in the water receiving tank, and the non-stop floor setting unit 11h. The functions of these functional units will be described in the following elevator control method.

[0054] In addition, the building warning device 13 monitors the building facilities installed in a building such as an apartment or a condominium. The building facilities are, for example, a water receiving tank, and an alarm is sent to the control center 11 when the water receiving tank is full. Such a building warning device 13 includes a control center communication unit 13a and a water receiving tank full water detection unit 13b. Among these, the control center communication unit 13a communicates with the control center 11 via the Internet network 10. The water receiving tank full water detection unit 13b is a sensor for detecting the full water of the water receiving tank of the building where the elevator 100a is installed.

[0055] The precipitation and wind volume information management server 12’ is an external server that handles meteorological information, and is, for example, a computer owned by the Japan Meteorological Agency or other weather forecasting companies.

[0056] <Elevator Control Method> Next, a first example and a second example of the elevator control method implemented by the above-described elevator control system 200 will be described in order.

[0057] [First Example] FIG. 6 is a flowchart showing a first example of the elevator control method of the second embodiment, and shows the procedure implemented according to the program of each part of the elevator control system 200 described with reference to FIG. 5. This flow shows the procedure of the operation in the "specific floor non-stop" mode, which is implemented as one of the operation modes during the flood evacuation operation.

[0058] Hereinafter, the procedure of the first example of the elevator control method will be described with reference to FIG. 5 along the flowchart of FIG. 6.

[0059] In step S301, the Internet network communication unit 11a of the control center 11 determines whether it has received a forecast that rain with a precipitation amount and a wind amount above a certain level will fall. At this time, based on the information received from the precipitation amount and wind amount information management server 12’, when there is a forecast of a precipitation amount and a wind amount above a certain level, the Internet network communication unit 11a determines that it has received the above forecast (YES) and proceeds to the next step S302. Note that the precipitation amount and wind amount above a certain level are values determined to be likely to allow rain to enter the building due to sideway rain and are preset.

[0060] In step S302, the elevator installation information management unit 11f of the control center 11 checks the elevator information in the area of the precipitation forecast. The area of the precipitation forecast is the area where the above forecast received in step S301 was issued. Here, the elevator installation information management unit 11f of the monitoring target holds, as elevator information, information such as the address of the building where each elevator is installed and the ease of rain entering from the outside to the elevator hall. The elevator installation information management unit 11f of the monitoring target checks the elevator information in the area where the above forecast was issued.

[0061] In step S303, based on the result of the check in step S302, the elevator installation information management unit 11f of the monitoring target determines whether there is an elevator with a specific floor facing the outside among the elevators installed in the area where the above forecast was issued. Here, that the specific floor faces the outside means that the hall door 7 faces the outside. If it is determined that there is an elevator (YES), it proceeds to step S304, and if it is determined that there is no elevator (NO), the process ends.

[0062] In step S304, the non-stop floor setting unit 11h transmits a specific floor non-stop setting to the target elevator determined to be an elevator having a structure in which the specific floor faces outward in step S303. At this time, in step S303, the non-stop floor setting unit 11h determines that the specific floor faces the outside and sets the specific floor as the non-stop floor of the target elevator 100a. Then, a specific floor non-stop setting that makes the specific floor non-stop is transmitted to the target elevator, and the process is terminated. Note that the specific floor may be all floors.

[0063] Also, the non-stop floor setting processing unit 9j of each elevator 100a that has received the specific floor non-stop setting sets the specific floor facing the outside as the non-stop floor. As a result, each elevator 100a operates in the "specific floor non-stop" mode with the specific floor facing the outside set as the non-stop floor. For example, in the case of the elevator 100a where only the elevator hall on the top floor faces the outside, when operating in the "specific floor non-stop" mode, the car 1 is not stopped at the top floor.

[0064] Also, the non-stop floor setting unit 11h may combine the "standby floor setting" mode described in step S104 of the first embodiment with the "specific floor non-stop" mode and set the floor without the influence of wind and rain as the standby floor.

[0065] When canceling the specific floor non-stop operation as described above, the drainage operation described using the flowchart of FIG. 3 explained in the first embodiment is performed. Note that the determination of canceling the operation in the "specific floor non-stop" mode may be made depending on whether the time limit for the flood evacuation operation setting has elapsed, similar to step S106 of the first embodiment.

[0066] [Effect of the First Example] According to the first example described above, it is possible to perform the flood evacuation operation without stopping the operation of the elevator 100a in accordance with the structure of the building in which the elevator 100a is installed.

[0067] [Second Example of Control Method] FIG. 7 is a flowchart showing a second example of the elevator control method according to the second embodiment, and shows procedures to be performed according to programs included in respective parts of the elevator control system 200 described with reference to FIG. 5. This flowchart shows procedures in the case of setting the flood evacuation operation for an elevator in which the flood evacuation operation described in the first embodiment is not set.

[0068] Hereinafter, with reference to FIG. 7 and while referring to FIG. 5, procedures of a second example of the elevator control method will be described.

[0069] In step S401, the water receiving tank full water detection unit 13b of the building warning device 13 determines whether or not it has detected full water in the water receiving tank. If it has detected full water (YES), the process proceeds to step S402.

[0070] In step S402, the control center communication unit 13a of the building warning device 13 transmits a full water detection signal to the control center 11 as an alarm. The building warning device abnormality management unit 11e of the control center 11 manages alarm information such as full water in the water receiving tank based on the full water signal received from the building warning device 13.

[0071] In step S403, the monitored elevator installation information management unit 11f of the control center 11 determines whether there is an elevator in the building that transmitted the full water detection signal in step S402. The monitored elevator installation information management unit 11f has information on buildings in which each elevator managed by the control center 11 is installed, and makes this determination based on this information. If it is determined that there is an elevator (YES), the process proceeds to step S404, and if it is determined that there is no elevator (NO), the process is terminated.

[0072] In step S404, the submergence evacuation operation setting unit 11b judges whether or not submergence evacuation operation has not been set for the elevator 100a in the building that transmitted the full water detection signal in step S402. The submergence evacuation operation setting unit 11b has information on whether or not submergence evacuation operation has been set for each elevator managed by the control center 11, and makes this judgment based on this information. If it is determined that submergence evacuation operation has not been set (YES), the process proceeds to step S405, and if it is determined that submergence evacuation operation has not been set (NO), the process ends. Note that for the elevator 100a for which it is determined that submergence evacuation operation has not been set (NO), submergence evacuation operation has already been set, and therefore submergence evacuation operation is performed according to that setting.

[0073] In step S405, the submergence evacuation operation setting unit 11b sets submergence evacuation operation for the elevator 100a in the building that transmitted the full water detection signal in step S402. At this time, the submergence evacuation operation setting unit 11b sets the submergence evacuation operation mode to either the "operation suspension" mode or the "standby floor setting" mode, and ends the process. After that, it is sufficient to proceed to step S102 in Fig. 2, and when the submergence evacuation operation is released, a drainage operation is performed.

[0074] The submergence evacuation operation setting unit 11b may set the mode of the submergence evacuation operation to the "standby floor setting" mode by the procedure of the first example described with reference to FIG.

[0075] [Effect of the second example] According to the second example described above, when an alarm occurs such as a water tank full due to a sudden downpour or a typhoon, if the flood evacuation setting has not been set for the elevator 100a in the building, the flood evacuation setting can be automatically set.

[0076] [Modification of the second example] In the second example described above, a configuration for automatically setting the flood evacuation setting for the elevator in the building where the water receiving tank is full was described. However, when there is another building with an elevator managed by the control center 11 near the building where the water receiving tank is full, the control center 11 may also automatically set the flood evacuation setting for the elevator in the other building. Note that the vicinity of the building shall be an area where the meteorological conditions are substantially the same as those of the location of the building and within the same weather forecast area. Also, another building includes a building without a water receiving tank and a building with a water receiving tank that is not full.

[0077] In such a case, when the control center 11 receives a full water detection signal, the elevator in the neighboring building of the building that sent the full water detection signal is identified by the neighboring elevator identification unit 11g for full water detection of the water receiving tank. Thereafter, proceed to step S404, and for each elevator identified by the neighboring elevator identification unit 11g for full water detection of the water receiving tank together with the elevator in the building, determine whether the flood evacuation operation is not set, and then proceed to step S405.

[0078] Furthermore, even when the control center 11 receives a full water detection signal from a building where no elevator is installed, the control center 11 may also automatically set the flood evacuation setting for the elevator in another building existing near the building that sent the full water detection signal.

[0079] As a result, even for the elevator 100a in a building without a water receiving tank or a building with a water receiving tank that is not full, if the flood evacuation setting is not set, the flood evacuation setting can be automatically set in response to the occurrence of a guerrilla heavy rain or a typhoon.

[0080] Note that the present invention is not limited to the above-described embodiments and modifications, and further includes various modifications. For example, the above-described embodiments have been described in detail for easy understanding of the present invention, and are not necessarily limited to those having all the configurations described.
