[0001] The present disclosure relates to an earthquake information display system for an elevator. [Background technology]

[0002] 2. Description of the Related Art Conventionally, elevators have been known that are equipped with earthquake sensors that detect earthquakes, and that perform earthquake controlled operation when the earthquake sensor detects an earthquake (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 2-123083 Summary of the Invention [Problem to be solved by the invention]

[0004] When an earthquake occurs, the earthquake detector detects the earthquake and the elevator performs earthquake controlled operation. This prevents passengers from becoming trapped inside the car. After the elevator performs earthquake controlled operation, workers perform recovery work for the elevator. After the workers have performed recovery work for the elevator, the elevator resumes normal operation.

[0005] When a large earthquake occurs, there is a possibility that aftershocks of a magnitude that would require elevators to operate under earthquake control will occur within a certain period of time after the large earthquake. However, some elevator users are worried that they will be trapped in the elevator car if another earthquake occurs. This creates a problem in that users who are worried will avoid using elevators until a certain period of time has passed since the large earthquake.

[0006] The present disclosure has been made to solve the problems described above, and its purpose is to provide an elevator earthquake information display system that can alleviate users' anxiety about being trapped inside the elevator car. [Means for solving the problem]

[0007] The elevator earthquake information display system according to the present disclosure is provided in an elevator car, and when an earthquake control operation is performed on the elevator, the elevator car displays the following information until a preset earthquake information notification time has elapsed from the time the earthquake control operation is performed: again The elevator is equipped with a display device that displays earthquake control operation information, which is information indicating that the elevator will perform earthquake control operation in the event of an earthquake. Effect of the Invention

[0008] The elevator earthquake information display system according to the present disclosure can alleviate passengers' anxiety about being trapped in the elevator car. [Brief description of the drawings]

[0009] [Figure 1] FIG. 1 is a block diagram showing an elevator equipped with an earthquake information display system for an elevator according to the first embodiment. [Diagram 2] FIG. 2 is a configuration diagram showing the main parts of the elevator in FIG. 1. [Diagram 3] 2 is a flowchart showing the operation of the elevator earthquake information display system of FIG. 1. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] Embodiment 1 Fig. 1 is a block diagram showing an elevator equipped with an earthquake information display system for elevators according to embodiment 1. Fig. 2 is a configuration diagram showing a main part of the elevator in Fig. 1. The elevator is equipped with a car 1 in which users get on and off.

[0011] The car 1 has a car body 101 and a car door 102. A car entrance 103 through which users pass is formed in the car body 101. The car door 102 is movable in an opening direction A of the car entrance 103. The car door 102 moves to open and close the car entrance 103. The car door 102 moves to switch the state of the car 1 between a door-closed state and a door-open state. The door-open state is a state in which the car entrance 103 is open, and the door-closed state is a state in which the car entrance 103 is closed by the car door 102.

[0012] The elevator also includes an elevator control panel 2. The movement of the car 1 and the movement of the car doors 102 are controlled by the elevator control panel 2.

[0013] The elevator also includes a car operation panel 3 and a speaker device 4. The car operation panel 3 and the speaker device 4 are each provided on a sleeve wall 104 of the car body 101.

[0014] The car operation panel 3 is operated by a user in the car 1. The car operation panel 3 has a number of buttons 301 corresponding to each of the number of floors of the building in which the elevator is installed. When the car operation panel 3 is operated, information on the operation of the car operation panel 3 is input to the elevator control panel 2. The information on the operation of the car operation panel 3 includes information identifying the button 301 that was operated.

[0015] The elevator control panel 2 moves the car 1 to the destination floor using information on the operation of the car operating panel 3. Therefore, the car 1 moves to the destination floor when a user in the car 1 operates the car operating panel 3. The destination floor is the floor that corresponds to the operated button 301.

[0016] The speaker device 4 makes announcements to passengers in the car 1. The announcements made by the speaker device 4 are controlled by the elevator control panel 2.

[0017] The elevator is also equipped with an earthquake detector 5 and an earthquake information display system 6.

[0018] The earthquake sensor 5 detects earthquakes in the area in which the building in which the elevator is installed is constructed. When the earthquake sensor 5 detects an earthquake, the detection result of the earthquake sensor 5 is input to the elevator control panel 2. In this example, the earthquake sensor 5 detects an earthquake when an earthquake with a seismic intensity of 4 or more occurs. Note that the earthquake sensor 5 may also detect an earthquake when an earthquake with a seismic intensity of 3 or less occurs.

[0019] When the detection result of earthquake detector 5 is input to elevator control panel 2, elevator control panel 2 moves car 1 to the nearest floor and sets the door of car 1 to an open state. The elevator operation in which car 1 moves to the nearest floor and the door of car 1 is set to an open state is called earthquake controlled operation of the elevator.

[0020] In the event of an earthquake, the elevator is operated under earthquake control, thereby preventing elevator users from becoming trapped inside the car 1.

[0021] After the elevator is put into earthquake controlled operation, workers perform the elevator recovery work. After the workers have performed the elevator recovery work, the elevator resumes normal operation.

[0022] The earthquake information display system 6 includes a display device 601 , an earthquake information acquisition device 602 , and a control device 603 .

[0023] The display device 601 is provided on the sleeve wall 104 of the car body 101. When the building in which the elevator is installed is a commercial facility, the display device 601 displays guide information for each of the multiple stores on each floor of the building.

[0024] The display device 601 also has a monitor for displaying images. The display device 601 displays earthquake controlled operation information. The earthquake controlled operation information is information indicating that the elevator will perform earthquake controlled operation when an earthquake occurs. An example of the earthquake controlled operation information is a video of the elevator performing an operation in which the car moves to the nearest floor and the car is in the door open state when an earthquake occurs. That is, an example of the earthquake controlled operation information is a video of the elevator performing earthquake controlled operation when an earthquake occurs. The video of the elevator performing earthquake controlled operation shows the car moving to the nearest floor and the car being in the door open state, and the user in the car evacuating to the nearest floor. Note that the earthquake controlled operation information is not limited to a video, and may be a still image.

[0025] By displaying earthquake control operation information on display device 601, the anxiety of elevator users that they may be trapped in car 1 in the event of an earthquake can be alleviated.

[0026] The earthquake information acquisition device 602 is composed of a communication device. The earthquake information acquisition device 602 is capable of communicating with an external information center 7. When an earthquake occurs, a group of earthquake information is input to the information center 7.

[0027] The earthquake information group input to the information center 7 includes information indicating the time when the earthquake occurred, information indicating the epicenter where the earthquake occurred, and information indicating the seismic intensity in each of a plurality of regions.

[0028] The earthquake information acquisition device 602 acquires earthquake information from the information center 7. The earthquake information acquired by the earthquake information acquisition device 602 from the information center 7 is part of the earthquake information group input to the information center 7. Specifically, the earthquake information acquired by the earthquake information acquisition device 602 from the information center 7 includes information indicating the time the earthquake occurred, information indicating the epicenter where the earthquake occurred, and information indicating the seismic intensity of the area where the elevator is installed. Note that the earthquake information acquired by the earthquake information acquisition device 602 from the information center 7 may be the same as the earthquake information group input to the information center 7.

[0029] The control device 603 controls each of the display device 601 and the earthquake information acquisition device 602. When an earthquake controlled operation of the elevator is performed, earthquake controlled operation implementation information is input from the elevator control panel 2 to the control device 603. The earthquake controlled operation implementation information is information indicating that an earthquake controlled operation of the elevator has been performed.

[0030] When earthquake controlled operation implementation information is input to the control device 603, the control device 603 causes the display device 601 to display earthquake controlled operation information from the time earthquake controlled operation is performed until the earthquake information notification time, which is a preset time, has elapsed. Therefore, it is possible to prevent users from avoiding using the elevator from the time an earthquake occurs until the earthquake information notification time has elapsed. For example, one week is set as the earthquake information notification time. Note that the earthquake information notification time is not limited to one week, and can be set to any time. In addition, the earthquake information notification time may change depending on the scale of the earthquake that has occurred. Specifically, the earthquake information notification time when a large-scale earthquake has occurred may be longer than the earthquake information notification time when a small-scale earthquake has occurred.

[0031] If a new earthquake controlled operation is performed before the earthquake information report time has elapsed since the previous earthquake controlled operation, the control device 603 causes the display device 601 to display earthquake controlled operation information from the time the new earthquake controlled operation was performed until the earthquake information report time has elapsed. When a large-scale earthquake occurs, there is a possibility that an aftershock of a magnitude that would cause the elevator to perform earthquake controlled operation will occur within a certain amount of time after the large-scale earthquake. Therefore, when a large-scale earthquake occurs and an aftershock occurs afterwards, the display device 601 displays earthquake controlled operation information in response to the occurrence of the aftershock.

[0032] When earthquake control operation implementation information is input to the control device 603, the control device 603 causes the earthquake information acquisition device 602 to acquire earthquake information from the information center 7. The earthquake information acquisition device 602 acquires earthquake information every time an earthquake occurs. Therefore, the earthquake information acquisition device 602 always acquires new earthquake information.

[0033] Furthermore, when earthquake controlled operation implementation information is input to the control device 603, the control device 603 causes the display device 601 to display the earthquake information acquired by the earthquake information acquisition device 602 from the time earthquake controlled operation is performed until the earthquake information alert time has elapsed. Therefore, it is possible to encourage users who use the elevator from the time the earthquake occurs until the earthquake information alert time has elapsed to prepare for an earthquake.

[0034] If a new earthquake control operation is performed before the earthquake information report time has elapsed since the previous earthquake control operation, the control device 603 causes the display device 601 to display earthquake information from the time the new earthquake control operation was performed until the earthquake information report time has elapsed. Therefore, if a large-scale earthquake occurs and aftershocks occur thereafter, the display device 601 displays earthquake information in response to the occurrence of the aftershock.

[0035] The display of earthquake controlled operation information and earthquake information by the display device 601 is started after an earthquake occurs, earthquake controlled operation of the elevator is performed, recovery work is performed by the operator, and the elevator resumes normal operation. Note that the display of earthquake controlled operation information and earthquake information by the display device 601 may be started after an earthquake occurs and earthquake controlled operation of the elevator is performed.

[0036] The speaker device 4 emits a sound corresponding to the earthquake control operation information and the earthquake information in accordance with the timing of display of the earthquake control operation information and the earthquake information on the display device 601, respectively.

[0037] Next, a description will be given of the operation of the elevator earthquake information display system 6. Fig. 3 is a flowchart showing the operation of the elevator earthquake information display system 6 of Fig. 1.

[0038] First, in step S101, an earthquake controlled operation determination step is performed. In the earthquake controlled operation determination step, the control device 603 determines whether or not an earthquake controlled operation of the elevator has been performed. The determination by the control device 603 of the presence or absence of an earthquake controlled operation is performed based on whether or not earthquake controlled operation implementation information has been input to the control device 603 from the elevator control panel 2.

[0039] In step S101, if the control device 603 determines that earthquake control operation is not being performed, the process of step S101 is repeated.

[0040] On the other hand, when the control device 603 determines in step S101 that an earthquake control operation has been performed, an earthquake information acquisition step is performed in step S102. In the earthquake information acquisition step, the earthquake information acquisition device 602 acquires earthquake information from the information center 7.

[0041] Thereafter, in step S103, a display start process is performed. In the display start process, the display device 601 displays the earthquake controlled operation information and the earthquake information. If the building in which the elevator is installed is a commercial facility and the display device 601 displays guidance information for each of a plurality of stores on each floor of the building, the display device 601 stops displaying the guidance information, and displays the earthquake controlled operation information and the earthquake information. In other words, the display device 601 stops normal display and displays the earthquake controlled operation information and the earthquake information.

[0042] Thereafter, in step S104, a step of determining whether or not an earthquake information report time has elapsed is performed. In the step of determining whether or not an earthquake information report time has elapsed, the control device 603 determines whether or not the earthquake information report time has elapsed since the earthquake control operation was performed.

[0043] In step S104, if the control device 603 determines that the earthquake information reporting time has not elapsed since the earthquake control operation was performed, the process of step S104 is repeated.

[0044] On the other hand, if the control device 603 determines in step S104 that the earthquake information notification time has elapsed since the earthquake control operation was performed, a display end step is performed in step S105. In the display end step, the display device 601 ends the display of the earthquake control operation information and the earthquake information. This ends the operation of the elevator earthquake information display system.

[0045] As described above, the elevator earthquake information display system 6 according to the first embodiment includes a display device 601 provided in the elevator car 1. When earthquake controlled operation of the elevator is performed, the display device 601 displays earthquake controlled operation information from the time earthquake controlled operation is performed until the earthquake information reporting time has elapsed. With this configuration, by having the user look at the display device 601, the user's anxiety about being trapped in the car can be alleviated.

[0046] Furthermore, the elevator earthquake information display system 6 includes an earthquake information acquisition device 602 that acquires earthquake information from the information center 7 when earthquake controlled operation is performed. From the time earthquake controlled operation is performed until the earthquake information alert time has elapsed, the display device 601 displays earthquake controlled operation information and the earthquake information acquired by the earthquake information acquisition device 602. With this configuration, by the user looking at the display device 601, it is possible to alleviate the user's anxiety about being trapped in the car and also to inform the user of earthquake information.

[0047] The earthquake information also includes information indicating the time the earthquake occurred, information indicating the epicenter of the earthquake, and information indicating the seismic intensity of the area the elevator is installed in. With this configuration, by the user looking at display device 601, the user can be notified of information indicating the time the earthquake occurred, information indicating the epicenter of the earthquake, and information indicating the seismic intensity of the area the elevator is installed.

[0048] Furthermore, when a new earthquake controlled operation is performed before the earthquake information alert time has elapsed since the previous earthquake controlled operation, the display device 601 displays earthquake controlled operation information from the new earthquake controlled operation until the earthquake information alert time has elapsed. With this configuration, when a new earthquake controlled operation is performed, the user can look at the display device 601 from the new earthquake controlled operation until the earthquake information alert time has elapsed, thereby eliminating the user's anxiety that he or she will be trapped in the car.

[0049] In the above-mentioned embodiment 1, the configuration of the earthquake information display system 6 including the display device 601 provided in the car 1 has been described. However, the earthquake information display system 6 may be configured to include a display device provided in the hall in addition to the display device 601 provided in the car 1. In this case, the display device provided in the hall has the same configuration as the display device 601 provided in the car 1. Therefore, like the display device 601 provided in the car 1, when an earthquake controlled operation of the elevator is performed, the display device provided in the hall displays earthquake controlled operation information from the time when earthquake controlled operation is performed until the earthquake information notification time has passed. According to this configuration, the user's anxiety that he or she will be trapped in the car can be eliminated by looking at the display device provided in the hall. In addition, like the display device 601 provided in the car 1, the display device provided in the hall may display earthquake controlled operation information and earthquake information from the time when earthquake controlled operation is performed until the earthquake information notification time has passed when an earthquake controlled operation of the elevator is performed. According to this configuration, by allowing passengers to look at the display device installed at the boarding area, it is possible to alleviate the passengers' anxiety about being trapped in the car and also to inform them of earthquake information.
