Embodiment 1 FIG.
1 is a side view showing an elevator apparatus according to Embodiment 1 of the present invention.
In FIG. 1, 1 is an elevator hoistway, 2 is an elevator hall, and 3 is an elevator car. FIG. 1 shows an example in which an elevator is installed in a four-story building. The hoistway 1 is formed so as to penetrate each floor (1st to 4th floors) of the building. The hall 2 is provided on each floor of the building. A landing door 4 is provided at each landing 2. The hall door 4 opens and closes the hall entrance / exit of the elevator. The car 3 moves up and down in the hoistway 1. A car door 5 is provided on the car 3. The car door 5 opens and closes the elevator car doorway.

  6 is a staircase provided in the building, and 7 is a rooftop exit room. The stairs 6 on the top floor leads to the rooftop exit room 7. A person in the building can go out from the rooftop exit room 7 to the rooftop 8 of the building. The door 9 for exiting from the roof outlet chamber 7 to the roof 8 is provided with an electromagnetic lock 10. The door 9 is normally locked by the electromagnetic lock 10. The electromagnetic lock 10 is unlocked by, for example, an unlock command from the control panel 13 described later.

  Reference numeral 11 denotes a key box installed in the rooftop exit chamber 7. When the door 9 is provided with a mechanical lock device instead of the electromagnetic lock 10, a key for unlocking the lock device is stored in the key box 11. In addition, an electromagnetic lock is provided on the door of the key box 11. The electromagnetic lock is unlocked by an unlock command from the control panel 13.

  An elevator machine room 12 is provided on the roof 8 of the building. The machine room 12 is disposed above the hoistway 1. The machine room 12 is provided with an elevator control panel 13 and a charging confirmation panel 14. A support 15 is provided on the outer wall surface of the machine room 12.

  The control panel 13 controls the operation of the elevator. For example, the control panel 13 controls the normal operation and control operation of the elevator based on various input information. The traveling control and door opening / closing control of the car 3 in various operations are performed by the control panel 13.

  The car 3 is connected to the control panel 13 by a control cable 16. The control cable 16 is composed of, for example, a power supply line or a transmission line. Other devices are connected to the control panel 13 by wiring 17. For example, the electromagnetic lock 10 and the charging confirmation panel 14 are connected to the control panel 13 by wiring 17.

The elevator and the building are provided with a plurality of submersion sensors 18a to 18d.
In the following, when it is not necessary to individually specify the submersion sensor, it is simply expressed as a submersion sensor 18.

  The submersion sensors 18a and 18b are provided in the car 3. The submergence sensor 18a is arranged so as to be able to detect, for example, submergence (flooding) at the floor level of the car 3. The submersion sensor 18b is disposed at a higher position in the car 3 than the submersion sensor 18a. The flooding sensor 18b detects flooding (flooding) at a position (predetermined height) higher than the position where the flooding sensor 18a detects flooding. The submersion sensors 18 a and 18 b are connected to the control panel 13 by the control cable 16.

  The submersion sensor 18 c is provided in the pit portion of the hoistway 1. The submergence sensor 18c is arranged so as to detect submergence (flooding) at a position lower than the hall 2 on the lowest floor. The submergence sensor 18c detects submergence at the bottom surface height of the pit portion, for example.

  The submersion sensor 18d is provided at the landing 2 on each floor of the building. The submergence sensor 18d is arranged so as to be able to detect, for example, submergence (flooding) at the height of the floor of the hall 2. When it is necessary to individually specify the submergence sensor 18d, a number indicating the number of floors is further added after the sign. For example, the submersion sensor installed in the hall 2 on the first floor is expressed as 18d-1. The submersion sensor installed in the hall 2 on the N floor is expressed as 18d-N. In the following description, other devices are individually identified by adding a number indicating the number of floors after the code as necessary. The submersion sensors 18 c and 18 d are connected to the control panel 13 by the wiring 17.

  19 is the Japan Meteorological Agency and 20 is the information center of the elevator. The control panel 13 receives a tsunami warning (tsunami warning) issued by the Japan Meteorological Agency 19 via the public line 21. The control panel 13 receives information on the tsunami (hereinafter referred to as “communication information”) from the information center 20 via the public line 21. The tsunami warning and communication information include information on a time when a tsunami is predicted to arrive (tsunami arrival prediction time) and information on a predicted tsunami height (tsunami predicted wave height).

  The control panel 13 has a function of performing a control operation (tsunami evacuation control operation) for minimizing damage caused by the tsunami. FIG. 2 is a diagram showing the configuration of the control panel of the elevator apparatus according to Embodiment 1 of the present invention. In order to realize the above functions, the control panel 13 includes a storage unit 22, a calculation unit 23, a control unit 24, and an information acquisition unit 25.

  The information acquisition unit 25 causes the storage unit 22 to store the predicted tsunami arrival time and the predicted tsunami wave height based on information acquired from the outside. When the control panel 13 receives a tsunami warning from the Japan Meteorological Agency 19 or communication information from the information center 20, the information acquisition unit 25 stores a predicted tsunami arrival time in the storage unit 22 based on the received tsunami warning / communication information. And the predicted tsunami wave height. The calculation unit 23 performs a predetermined calculation based on the predicted tsunami arrival time and the predicted tsunami height stored in the storage unit 22. The control unit 24 appropriately controls the tsunami evacuation control operation based on the calculation result of the calculation unit 23 and other input information.

  The information acquisition unit 25 includes a specifying unit 25a. The identification unit 25 a is provided in the information acquisition unit 25 for an elevator that cannot receive information from the Japan Meteorological Agency 19 or the information center 20. The identifying unit 25a identifies the predicted tsunami arrival time and the predicted tsunami height based on information other than the tsunami warning and communication information.

  Table 1 shows an example of the semi-communication information. The quasi-communication information is information necessary for the identifying unit 25a to identify the predicted tsunami arrival time and the predicted tsunami wave height.

  In the example shown in Table 1, the reliability is set in advance for information that can be a trigger when starting the tsunami evacuation control operation. For example, the highest reliability (for example, 10 points) is given to the tsunami warning from the Meteorological Agency 19 and the communication information from the information center 20. If the control panel 13 cannot receive information from the Japan Meteorological Agency 19 or the information center 20, it is not necessary to consider this field. In addition, when the control panel 13 can receive information from the Japan Meteorological Agency 19 or the information center 20, the information acquisition unit 25 stores the information in the storage unit 22 based on the received tsunami warning / communication information regardless of the presence or absence of other information. You may memorize | store tsunami arrival prediction time and tsunami prediction wave height.

  For the information obtained from evacuees in the building, a lower reliability than the tsunami warning and communication information is set. For example, the next highest reliability (for example, 5 points) is given to information obtained from a so-called evacuation instructor such as a person responsible for guidance during evacuation. On the other hand, low reliability is given to information obtained from general evacuees. For example, among the information obtained from the general evacuees, 1 point is given as the reliability for highly public information such as TV and radio. Among the information obtained from general evacuees, 0.5 points are assigned as reliability for information sources with low publicity such as other evacuees.

  In order to realize the above function by the specifying unit 25a, a device (input device: not shown in FIGS. 1 and 2) for an evacuee in the building to input predetermined information regarding the tsunami to the hall 2, the car 3, etc. ) Is provided. Details of the input device will be described later. The identifying unit 25a identifies the predicted tsunami arrival time and the predicted tsunami height based on information input from the input device.

FIG. 3 is a front view showing a landing on the first floor of the elevator apparatus according to Embodiment 1 of the present invention. The hall 2 on the other floor has the same configuration as that shown in FIG.
The hall 2 on the first floor is provided with a hall operating panel 26, a display 27, and a discriminator 28 on the wall surface adjacent to the hall entrance.

The hall operation panel 26 is for the user to operate at the hall 2. The hall operation panel 26 includes, for example, an UP button and a DOWN button for registering a hall call, and an UP lamp and a DOWN lamp that indicate a registration direction of the call.
The display device 27 is for providing information to users at the hall 2. The display device 27 displays characters, designs, and the like.

  The discriminator 28 is a device used for performing various discriminations. The discriminator 28 includes a camera for photographing the user's face, a microphone for listening to the user's voice, a speaker for playing a message, and the like. Image information and audio information acquired by the discriminator 28 are transmitted to the control panel 13. The discriminator 28 may be used as the input device.

  For example, the specifying unit 25a classifies information input from the discriminator 28 based on the information source. The identification unit 25a identifies the predicted tsunami arrival time and the predicted tsunami wave height based on the number of information for each classification and the reliability for each classification.

  For example, the specifying unit 25a multiplies the number of information and the reliability for each classification, and stores the obtained score in the storage unit 22. In the example shown in Table 1, if the voice data is input 12 times by the evacuation instructor, the score of classification I2 is 12 × 5 = 60. Similarly, if the number of information of class I3 is 50, the score of class I3 is 50, and if the number of information of class I4 is 80, the score of class I4 is 40. The identifying unit 25a employs the classification information having the highest score as information for identifying the predicted tsunami arrival time and the predicted tsunami wave height.

Next, the basic operation of the tsunami evacuation control operation based on the predicted tsunami arrival time will be described.
The computing unit 23 calculates a basic time related to the tsunami evacuation control operation based on the predicted tsunami arrival time stored in the storage unit 22. The basic time calculated by the calculation unit 23 is stored in the storage unit 22.
Table 2 shows an example of the basic time set by the calculation unit 23.

Table 2 shows a case where the calculation unit 23 sets four types of basic times (time t1, time t2, time t3, and time t4 in order from the earliest time).
Time t1 is the time when the tsunami warning or tsunami warning is issued. The time t1 is set based on the information stored in the storage unit 22. Time t <b> 4 is a predicted tsunami arrival time stored in the storage unit 22.

  Time t3 is an elevator usage limit time. During the tsunami evacuation control operation, use of the elevator is restricted by time t3. At time t3, subsequent use of the elevator is not permitted. That is, the control unit 24 forcibly stops the elevator at time t3. For example, the time t3 is set to a time that is a predetermined time before the time t4.

  Time t2 is the evacuation start limit time of the evacuation priority person. An evacuation priority person is a person who can prioritize and use an elevator during evacuation. Wheelchair users, etc. fall under priority for evacuation. The time t2 is set to a time that is a predetermined time before the time t3, for example. For example, the storage unit 22 stores predetermined information regarding evacuation priority persons in buildings. Based on the information stored in the storage unit 22, the calculation unit 23 calculates an evacuation time required for all evacuation priority persons in the building to evacuate using an elevator. For example, (evacuation priority number) × (time required for evacuation) is defined as the evacuation time. The calculation unit 23 sets a time t2 before the evacuation time (or a time obtained by adding a predetermined margin time to the evacuation time) from the time t3.

  Immediately after time t1, there is a little room until the predicted tsunami arrival time (time t4). The control unit 24 performs an operation (priority operation) that preferentially evacuates the evacuation priority person in the building to the upper floor from time t1 to time t2. That is, when the current time becomes time t1 (or when the current time has passed time t1), the control unit 24 controls the priority operation. In priority driving, evacuation priority is given priority to evacuation using an elevator. In priority driving, general refugees (evacuees other than evacuation priority persons) are allowed to evacuate using an elevator.

  Time t2 is the last time that all evacuation priority persons in the building can evacuate before the elevator stops. When the current time is time t2, the priority operation is terminated and the dedicated operation is started. The control unit 24 controls a dedicated operation for evacuating the evacuation priority person in the building to the upper floor from time t2 to time t3. Dedicated driving is for refuge priority people. In exclusive operation, evacuation using an elevator is restricted to evacuation priority persons. General evacuees are not allowed to evacuate using elevators. The general refugee evacuates using the stairs 6.

When the current time is time t3, the exclusive operation is terminated and the elevator is stopped. Thereby, for example, the elevator is in a pause state several minutes before the predicted arrival time of the tsunami. The stop of the elevator is continued from time t3 to time t4.
The above is the basic operation of the tsunami evacuation control operation starting from time t1.

Next, the basic operation of the tsunami evacuation control operation based on the predicted tsunami height will be described.
The control unit 24 determines an operation to be performed in the tsunami evacuation control operation based on the predicted tsunami height stored in the storage unit 22. For example, the control unit 24 determines whether to perform priority operation or dedicated operation based on the predicted tsunami wave height. Furthermore, the control unit 24 controls a necessary evacuation operation based on the predicted tsunami wave height.
Table 3 shows an example of operations performed in the tsunami evacuation control operation.

  Table 3 shows a case where the operation in the tsunami evacuation control operation is changed according to four types of basic heights (heights h0, h1, h2, h3 in order of increasing wave height).

  For example, when the predicted tsunami height is equal to or lower than the floor surface of the first floor (of landing 2) (height h0), the control unit 24 determines that there is almost no danger from the tsunami. In such a case, the control unit 24 continues the normal operation until time t3 even after time t1 has elapsed. That is, priority operation and exclusive operation are not performed. At time t3, the control unit 24 ends the normal operation and stops the elevator. The time (time from time t3 to time t4) for making the elevator stand by in a stop state is set to a predetermined short time.

  When the predicted tsunami height is, for example, higher than the floor surface of the first floor (height h0 or more) and 15 cm or less (height h1) on the first floor, the control unit 24 starts priority operation at time t1. . At time t2, the control unit 24 ends the priority operation and starts the dedicated operation. The control unit 24 stops the elevator at time t3. The elevator standby time is set to a predetermined short time.

  When the predicted tsunami wave height is, for example, higher than 15 cm above the floor on the first floor (height h1 or higher) and below the floor surface of the (top-1) floor (height h3 or lower), the control unit 24 becomes time t1. Does not perform priority operation. The control unit 24 starts a dedicated operation at time t2. The control unit 24 stops the elevator at time t3. The elevator standby time is set to a predetermined long time.

Furthermore, when the predicted tsunami wave height reaches the floor surface (height h2) of the (top-2) floor, the control unit 24 stops the elevator and then shuts off the elevator power. When the predicted tsunami wave height reaches the floor surface (height h3) of the (top-1) floor, the control unit 24 unlocks the electromagnetic lock 10 and secures an evacuation route to the rooftop 8.
The above is the basic operation of the tsunami evacuation control operation corresponding to the basic height.

  The predicted tsunami arrival time and the predicted tsunami wave height stored in the storage unit 22 are merely predicted values. An actual tsunami may reach the building earlier than the predicted tsunami arrival time. When a tsunami reaches a building during dedicated operation, various obstacles due to flooding may occur. This elevator apparatus is provided with a function (shut-off function) that shuts off the electrical connection of devices as a means for avoiding the above-mentioned obstacles.

The actual tsunami wave height may be higher than the predicted tsunami wave height. For example, the tsunami wave height may be higher than that of a building. This elevator apparatus also has a function (evacuation support function) for assisting evacuees when the tsunami wave height is higher than that of the building.
Hereinafter, the configuration for realizing the blocking function and the evacuation support function will be described in detail with reference to FIGS.

  FIG. 4 is a side view showing a main part of the elevator apparatus according to Embodiment 1 of the present invention. FIG. 4 shows a state in which the machine room 12 and the first floor of the building are viewed from the side.

A door switch 29 is provided corresponding to the landing door 4 on the first floor. The door switch 29 is a switch for detecting that the landing door 4 is completely closed. The door switch 29 is connected to the control panel 13 by the wiring 17 in the same manner as the submergence sensor 18d-1, the hall operation panel 26, the display device 27, and the discriminator 28.
Similarly, in the hall 2 on the other floor, the flood sensor 18d, the hall operation panel 26, the display 27, the discriminator 28, and the door switch 29 are connected to the control panel 13 by the wiring 17.

  5 and 6 are diagrams showing circuit configurations relating to landing equipment of the elevator apparatus according to Embodiment 1 of the present invention. 5 and 6, reference signs + and − indicate elevator control power lines formed in the control panel 13. 5 and 6, the circuit inside the control panel 13 is indicated by a solid line, and the circuit outside the control panel 13 is indicated by a broken line.

  Reference numeral 30 denotes a contact point of the submersion sensor 18d. The contact 30 is a B contact. The contact 30-1 of the first floor flood sensor 18d-1 is disconnected when the flood sensor 18d-1 detects the flood. Reference numeral 31 denotes a separation contact formed of a B contact. The separation contact 31-1 on the first floor is disconnected when the wiring 17 of the hall 2 on the first floor is disconnected in advance. S is a relay with time-deactivation time limit (hereinafter simply referred to as “time relay S”), and SA is a contact point (A contact point) of the time limit relay S. SN is a relay without time limit (hereinafter, simply referred to as “relay SN”), and SNB is a contact (contact B) of the relay SN.

  The hall device circuit 32 is a circuit for a device (landing device) installed in the corresponding hall 2 (and its peripheral portion). The submersion sensor 18d, the hall operation panel 26, the display 27, the discriminator 28, and the door switch 29 are connected to the control board 13 via the hall device circuit 32 (and the wiring 17). The hall device circuit 32 is connected to the power line + through the contact SA. The hall device circuit 32 is connected to the power supply line − through another contact SA.

  In normal times, the contact 30-1 and the separation contact 31-1 are closed, and the time relay S-1 is energized. If the time relay S-1 is energized, the contact SA-1 is closed. A predetermined voltage is supplied between the power supply lines + and −, and the landing equipment on the first floor is electrically connected to the control panel 13.

  When the contact 30-1 or the separation contact 31-1 is disconnected, the time relay S-1 and the relay SN-1 are deactivated. As a result, the contact SA-1 connected to the power line + and the contact SA-1 connected to the power line-are disconnected. Electricity is not supplied to the hall device circuit 32-1, and the hall device on the first floor is electrically disconnected from the control panel 13.

  For example, when the first floor flood sensor 18 d-1 detects flooding, the first floor landing equipment is electrically disconnected from the control panel 13. In addition, the separation means in the hall 2 on the first floor is configured by the contact 30-1, the time relay S-1, and the contact SA-1. At this time, if the second floor flood sensor 18 d-2 does not detect flooding, the second floor hall device remains electrically connected to the control panel 13. Thereafter, when the water surface rises and the second floor flood sensor 18d-2 detects the flood, the second floor landing equipment is electrically disconnected from the control panel 13. At this time, if the submergence sensor 18d-3 on the third floor has not detected submergence, the landing equipment on the third floor remains electrically connected to the control panel 13.

  Thus, according to the situation of flooding, electrical disconnection can be performed in order from the landing equipment installed below. Note that the separation means in the Nth floor hall 2 includes a contact 30-N, a timed relay SN, and a contact SA-N.

  DS shown in FIG. 6 is a contact point of the door switch 29. The time relay S in the control panel 13 is energized when enabling the landing equipment on the first floor. The contact DS-1 of the door switch 29-1 on the first floor is connected between the contacts SA-1. The contact SA-1, the contact DS-1, and the contact SA-1 connected in series are connected in parallel to the contact SNB-1 of the relay SN-1. Similarly, the contact DS-2 of the door switch 29-2 on the second floor is connected between the contacts SA-2. The contact SA-2, contact DS-2, and contact SA-2 connected in series are connected in parallel to the contact SNB-2 of the relay SN-2. The contact SA-2, contact DS-2, and contact SA-2 connected in series are connected in series to the contact SA-1, contact DS-1, and contact SA-1. That is, the contacts DS of the door switches 29 on each floor are connected in series.

  The DSL is a relay that is energized when the contacts DS of all door switches 29 are closed (connected). That is, during normal times, the relay DSL is energized if all the landing doors 4 are completely closed.

For example, consider a case where submergence is detected by the submergence sensor 18d-1 on the first floor.
When the submergence sensor 18d-1 detects submergence, the contact 30-1 is disconnected. When the contact 30-1 is disconnected, the contact SA-1 of the time relay S-1 is disconnected after maintaining the communication state for a certain time. Further, when the contact 30-1 is disconnected, the contact SNB of the relay SN-1 is instantaneously closed and turned on. For this reason, it is possible to keep the relay DSL in the state after disconnecting the contact DS-1 of the door switch 29 on the first floor where there is a risk of flooding. Other circuits using the relay DSL are not affected by flooding. That is, there is no possibility that the circuit in the control panel 13 is affected by the flooded floor (electric shock, electric leakage, short circuit, etc.).

Next, an electrical interrupting function for a device (cage device) installed in the car 3 will be described.
FIG. 7 is a front view showing a car of the elevator apparatus according to Embodiment 1 of the present invention. The car 3 includes various car devices in addition to the above-described submersion sensors 18a and 18b. For example, the car 3 includes a car operation panel 33, a scale device 34, a photoelectric device 35, a multi-axis beam device 36, a car lower illumination 37, and an SDE switch 38.

The car operation panel 33 is for operation by a user in the car 3. The car operation panel 33 includes, for example, an interphone 39 in addition to an open button and a close button for opening and closing the car door 5, a destination floor button corresponding to each destination floor, and a display.
The scale device 34 detects the loaded load of the car 3. Detection of excessive riding on the car 3 is performed based on the load detected by the scale device 34.

The photoelectric device 35 and the multi-axis beam device 36 are for holding the car door 5 (and the landing door 4) in an open state when the user enters and leaves the car 3.
The car lower illumination 37 is for illuminating the lower part of the car 3. The undercarriage illumination 37 is used during elevator maintenance or the like.

  The SDE switch 38 is for preventing a user from colliding with the car door 5. The safety bar 40 is provided on the car door 5 via the link 41 so as to protrude from the door end of the car door 5. When the safety bar 40 moves in the door closing direction with respect to the car door 5, the link 41 operates the SDE switch 38. When the SDE switch 38 is operated, the car door 5 is reversed to perform the door opening operation.

  A car upper box 42 is provided at the top of the car 3. The control cable 16 passes through the side of the car 3 and its end is connected to the car upper box 42. A wiring 43 is connected between the car upper box 42 and each car device. That is, the submersion sensors 18a and 18b, the car operation panel 33, the scale device 34, the photoelectric device 35, the multi-axis beam device 36, the car lower illumination 37, and the SDE switch 38 are connected via the wiring 43, the car upper box 42, and the control cable 16. Connected to the control panel 13.

  For a device installed in the car 3, a predetermined car device is electrically disconnected from the control panel 13 by a method similar to the method described with reference to FIGS. For example, when submersion is detected by the submersion sensor 18a, a contact point (not shown) of the submersion sensor 18a is disconnected and a predetermined car device is electrically disconnected from the control panel 13. The contact point of the flood sensor 18a constitutes a part of the separating means in the car 3.

  Among the car devices, the car operation panel 33 is an apparatus necessary for carrying out the tsunami evacuation control operation. In an emergency elevator that performs fire fighting operation, the car operation panel 33 is waterproofed. For this reason, the car operation panel 33 does not break down to the extent that the water is slightly applied. However, even such a car operation panel 33 cannot withstand submergence. The submersion sensor 18 b is installed below the car operation panel 33 and in the vicinity of the lower end of the car operation panel 33. The submergence sensor 18b is arranged so that submersion at a position below the car operation panel 33 can be detected before the car operation panel 33 is submerged.

  Of the car equipment, the SDE switch 38 is an apparatus necessary for safety when performing the tsunami evacuation control operation. The SDE switch 38 is disposed above the flood sensor 18b, for example, above the car 3.

  In addition, the said height h1 is the limit height of the water surface for operating the cage | basket | car 3 normally in a tsunami escape control operation. As described above, when the floor surface of the car 3 is submerged, the car devices other than the car operation panel 33 and the SDE switch 38 are disconnected from the control panel 13. For this reason, even if the floor surface of the car 3 is submerged, the car 3 operates normally. If the water surface is lower than the lower end of the car operation panel 33 (for example, a height of about 50 cm from the floor surface of the car 3), the car 3 can be operated by a command from the car operation panel 33. Moreover, if the flooding is about 20 cm from the floor of the car 3, the door opening and closing operation can be performed normally. In the present embodiment, in consideration of safety, the height h1 is set to 15 cm or less on the first floor.

    If submersion is detected by the submersion sensor 18b during priority operation or dedicated operation, the control unit 24 moves the car 3 upward so that the submersion is not detected by the submersion sensor 18b, for example. By performing such an operation, both the car operation panel 33 and the SDE switch 38 can be utilized until a series of operations of the tsunami evacuation control operation is completed.

Next, a function for cutting off the power supply of the elevator will be described.
FIG. 8 is a side view showing a main part of the elevator apparatus according to Embodiment 1 of the present invention. FIG. 8 shows a state in which the machine room 12 and the floor one floor below the top floor of the building (hereinafter referred to as the third floor in accordance with the present embodiment) are viewed from the side.

  The control panel 13 includes a breaker lever 44 on the front of the panel. For example, when the breaker lever 44 is moved downward, the power source of the elevator (control panel 13) is shut off. The power shut-off means 45 is for forcibly shutting off the power source of the elevator when it is submerged to a predetermined height below the control panel 13. For example, when the power shut-off means 45 floods the third floor of the building, the power shut-off means 45 drops the breaker lever 44 and shuts off the power.

  The power shut-off means 45 includes, for example, pulleys 46a to 46f, a gear 47, a weight 48, wires 49a and 49b, a claw portion 50, a lock device 51, a float case 52, and a float 53.

The pulleys 46a to 46f are provided with a horizontal rotation axis.
The pulley 46 a, the pulley 46 b, and the pulley 46 c are rotatably provided on the side surface of the control panel 13. The pulley 46a is disposed on the front side of the panel, and the pulley 46b is disposed on the rear side. The pulley 46a and the pulley 46b are disposed at substantially the same height. The pulley 46c is disposed above the pulley 46b. The gear 47 is provided integrally with the pulley 46b. That is, the gear 47 rotates together with the pulley 46b and stops.

  The weight 48 is provided at one end of the wire 49a. The wire 49a is wound around the pulley 46b and the pulley 46a from one end side. A claw portion 50 is provided at the other end portion of the wire 49a. The claw portion 50 is for moving the breaker lever 44 downward. When the wire 49a moves to one end side from the predetermined position, the claw portion 50 pulls down the breaker lever 44.

  The lock device 51 is a device for preventing the rotation of the pulley 46b. When the locking device 51 comes into contact with the gear 47 from above and meshes with the gear 47, the rotation of the gear 47, that is, the rotation of the pulley 46b is prevented. Under normal conditions, the locking device 51 is engaged with the gear 47. For this reason, the wire 49a is held at the predetermined position, and the claw portion 50 does not pull down the breaker lever 44.

  The pulley 46 d is rotatably provided on the fixed body of the machine room 12. The pulley 46d and the pulley 46c are disposed at substantially the same height. The pulleys 46e and 46f are rotatably provided on the fixed body of the hoistway 1. The pulleys 46e and 46f are arranged below the floor surface of the hall 2 on the third floor. The pulley 46e is disposed immediately below the pulley 46d. The pulleys 46e and 46f are arranged at substantially the same height.

  The float case 52 is provided above the pulley 46f. A float 53 is disposed inside the float case 52. One end of the wire 49 b is connected to the lock device 51. The wire 49b is wound around the pulley 46c, the pulley 46d, the pulley 46e, and the pulley 46f sequentially from one end side. The other end of the wire 49 b is connected to the float 53.

  Considering that the car 3 evacuates to the top floor when a large tsunami reaches the building, the power shut-off means 45 drops the breaker lever 44 and shuts off the power when the building is flooded to the third floor. That is, when water enters the hoistway 1 and the water surface reaches the vicinity of the third floor, the float 53 floats, and the float 53 pulls the wire 49b to the other end side. When the water surface reaches the floor surface of the third floor hall 2 and the third floor hall 2 is submerged, the wire 49b lifts the lock device 51, and the lock device 51 is disengaged from the gear 47. Thereby, the load by the weight 48 acts on the wire 49a, and the claw part 50 pulls down the breaker lever 44.

  The lock device 51 is released by the wire 49b and also released by an electric signal from the control panel 13.

Next, the evacuation support function will be described.
FIG. 9 is a diagram showing a rooftop of a building provided with the elevator apparatus according to Embodiment 1 of the present invention. A wall 54 forming the machine room 12 is provided on the roof 8 of the building. The support 15 is fixed to the wall body 54.

  Reference numeral 55 denotes an evacuation device box provided on the wall body 54, and 56 denotes an electromagnetic lock for locking the door of the evacuation device box 55. The door of the evacuation equipment box 55 is normally locked with an electromagnetic lock 56. The electromagnetic lock 56 is unlocked by an unlock command from the control panel 13, for example. Thereby, the door of the refuge tool box 55 can be opened.

FIG. 10 is a view showing the inside of the evacuation equipment box. FIG. 11 is a diagram showing the stored items in the evacuation equipment box.
The inside of the evacuation equipment box 55 is divided by a shelf 57, and a large number of life jackets 58 are stored. In the life jacket 58, a mobile phone 59 having a GPS function and a waterproof function is placed in each pocket. The mobile phone 59 is always supplied with AC 100V power from the control panel 13. For this reason, if it is stored in the evacuation equipment box 55, the mobile phone 59 is basically fully charged. A signal indicating the charging state of the mobile phone 59 is transmitted to the charging confirmation panel 14. The charging confirmation board 14 displays the charging state of each mobile phone 59 based on the received information. The elevator maintenance staff can check the charging state of each mobile phone 59 by looking at the display on the charging confirmation panel 14.

  FIG. 11 shows a state in which the life jacket 58 is taken out of the shelf 57 and spread. Reference numeral 60 denotes a belt that is fastened and fixed so as not to loosen when the life jacket 58 is worn. A reel 61 is provided on the belt 60. A wire 62 is wound around the reel 61. If the wire 62 is pulled to the tip side, the wire 62 can be unwound from the reel 61. The wire 62 is provided with a hook 63 at the tip. The hook 63 is hooked on a part of the reel 64 and connected to the reel 64. A wire 65 is wound around the reel 64. If the wire 65 is pulled toward the distal end side, the wire 65 can be fed out from the reel 64. The wire 65 is provided with a hook 66 at the tip. In this manner, the two-tiered hooks with reels are connected to the belt 60.

  Next, the operation and function of the elevator apparatus having the above-described configuration will be specifically described with reference to FIGS. FIG. 12 is a flowchart showing the operation of the elevator apparatus according to Embodiment 1 of the present invention.

  The control panel 13 determines whether any of the tsunami warning, the tsunami warning, or the communication information has been received (S101). When the control panel 13 receives, for example, a tsunami warning, the tsunami arrival prediction time and the tsunami prediction wave height are stored in the storage unit 22 (Yes in S102).

  In an elevator apparatus that cannot receive information from the Japan Meteorological Agency 19 or the information center 20, for example, the control panel 13 acquires semi-communication information using the discriminator 28 installed at the hall 2. FIG. 13 is a diagram for explaining the operation of the elevator apparatus according to Embodiment 1 of the present invention. FIG. 13 shows a state where the evacuees are uttering that a tsunami is coming toward the microphone of the discriminator 28.

  The audio information acquired by the microphone of the discriminator 28 is transmitted to the control panel 13. The identifying unit 25a detects that the tsunami may reach the building based on the voice information input from the discriminator 28. In such a case, the control panel 13 displays information for acquiring quasi-communication information on the display 27 of each hall 2. FIG. 14 to FIG. 16 are diagrams for explaining the operation for acquiring the semi-communication information. 14 to 16 show the indicator 27 and the discriminator 28 installed at the hall 2.

  FIG. 14 is a display example of the display device 27 for acquiring information related to the information source. FIG. 15 is a display example of the display device 27 for acquiring information related to the predicted arrival time of the tsunami. FIG. 16 is a display example of the display device 27 for acquiring information related to the predicted tsunami wave height. The refugee who sees the display on the display 27 inputs information on the information source, the arrival time of the tsunami, the tsunami wave height, and the like from the microphone of the discriminator 28. The identifying unit 25a identifies the predicted tsunami arrival time and the predicted tsunami wave height based on the voice information input from the discriminator 28, and stores the identified contents in the storage unit 22 (Yes in S102).

  FIG. 17 is a diagram showing another configuration example of the elevator hall. As shown in FIG. 17, a numeric keypad 67 (display with numeric keypad 27) is installed at the hall 2, and an evacuee inputs information on the information source, the arrival time of the tsunami, the tsunami wave height, etc. from the numeric keypad 67. Also good.

  When the predicted tsunami arrival time and the predicted tsunami wave height are stored in the storage unit 22, the calculation unit 23 calculates time t <b> 2 and time t <b> 3 based on the storage content of the storage unit 22. Moreover, the calculating part 23 calculates the floor (submerged floor) which will be submerged when the tsunami arrives based on the memory content of the memory | storage part 22. FIG. Information about time t2, time t3, and the submerged floor calculated by the calculation unit 23 is displayed on the display 27 of each landing 2 (S103).

  18 and 19 are diagrams for explaining information provided to evacuees. 18 and 19 show examples of contents displayed on the display 27 of each hall 2 in S103.

  As a result of the calculation performed by the calculation unit 23, when it is determined that the entire floor of the building is not submerged (for example, when the tsunami prediction wave height is the height h0) (S104), the control unit 24 until the time t3, Normal operation is continued (S105).

When it is determined that a part of the building is submerged (for example, when the predicted tsunami height is from h1 to h3) (S106), the control unit 24 performs priority operation and dedicated operation according to the situation (S107).
For example, when the predicted tsunami height is the height h1, the control unit 24 starts the priority operation at time t1. In priority operation, evacuees are evacuated to a floor above the submerged floor. When the predicted tsunami height is not less than h1 and not more than h3, the control unit 24 starts a dedicated operation at time t2. In exclusive operation, evacuees are evacuated to a floor above the submerged floor. FIG. 20 is a diagram for explaining information provided to evacuees. FIG. 20 shows an example of the contents displayed on the display 27 of each hall 2 when the dedicated operation is performed.

  When it is determined that the entire building is submerged (for example, when the predicted tsunami height is greater than or equal to the height h3) (S108), the control unit 24 does not perform the priority operation. The control unit 24 starts a dedicated operation at time t2. In exclusive operation, evacuees are evacuated to the top floor. In addition, the control unit 24 unlocks the electromagnetic lock 10 of the door 9 provided in the rooftop exit chamber 7. Thereby, the evacuees can evacuate from the rooftop exit chamber 7 to the rooftop 8. Further, the control unit 24 unlocks the electromagnetic lock 56 of the door of the evacuation equipment box 55 provided on the rooftop 8 (S109).

  At time t3 (Yes in S110), in preparation for the arrival of the tsunami, the control unit 24 stops the elevator entirely (S111). After the time t3 has elapsed, the car 3 does not travel and does not open or close the door, and stands by on the top floor of the building. The landing equipment on the submerged floor is disconnected from the electrical connection to the control panel 13.

  When the tsunami reaches the building and the floor above the submerged floor calculated by the calculation unit 23 is submerged, the submersion sensor 18d of the landing 2 detects the submersion, as described above, and the landing 2 The hall device is electrically disconnected from the control panel 13. When the tsunami reaches the building, if the floor one floor below the top floor of the building is submerged, the power of the elevator (control panel 13) is shut off by the power shut-off means 45.

  FIG. 21 is a flowchart showing the operation of the elevator apparatus according to Embodiment 1 of the present invention. FIG. 21 shows the operation during priority operation.

  During priority operation, the control unit 24 determines whether or not there is an evacuation priority person, that is, whether or not the evacuation priority person is going to evacuate using an elevator (S201). The evacuation priority person registers information (personal information) for specifying an individual in the storage unit 22 in advance. The evacuation priority person inputs personal information at the landing 2 when evacuating using an elevator. For example, the evacuation priority person inputs a face image and fingerprint information from the discriminator 28. Alternatively, the evacuation priority person inputs a password from the display 27 with a numeric keypad.

  Personal information entered by the evacuation priority person at the hall 2 is transmitted to the control panel 13. The control unit 24 compares the input personal information with the pre-registered personal information, and determines that there is an evacuation priority person if the input personal information exists in the registered information (S201). Yes).

When the control unit 24 confirms the existence of the evacuation priority person, the control unit 24 performs a predetermined display on the display 27, and states that "the evacuation priority person gets on the car 3 and the general refugee evacuates using the stairs 6". Is notified (S202). Furthermore, if the presence of an evacuation priority person is confirmed, the control part 24 will drive | operate in a wheelchair use mode, such as dropping a door opening / closing speed (S203).
In the case of exclusive operation, information indicating that “a general refugee cannot ride in the car 3” is displayed on the display 27.

Next, a detailed operation after time t2 will be described with reference to FIG.
FIG. 22 is a flowchart showing the operation of the elevator apparatus according to Embodiment 1 of the present invention.

  At time t2, a dedicated operation in which evacuation by the elevator is restricted to evacuation priority persons is performed. The dedicated driving is, for example, driving with a driver using an evacuation instructor as a driver. If there is a driver, even if a tsunami reaches the building during dedicated driving, it can respond appropriately to the emergency and help the evacuation priority person.

  After time t2, when the car 3 stops at the landing 2 on the first floor, the control unit 24 stores the elapsed time (door opening time) after opening the car door 5 (and the landing door 4) in the storage unit 22. (S301). Further, the control unit 24 determines whether or not the tsunami has reached the building before the predicted tsunami arrival time (S302).

  If the tsunami arrival prediction is lost and the tsunami reaches the building before the tsunami arrival prediction time (Yes in S302), the control unit 24 appropriately controls the operation of the elevator in accordance with the situation at that time.

  When it is detected that the tsunami has reached the building during the exclusive operation, the control unit 24 first determines whether or not the elevator car 3 is traveling (S303). If the car 3 is stopped (No in S303), the control unit 24 next determines whether or not the car 3 is stopped on the first floor (the lowest floor) (S304).

  When the car 3 is stopped on a floor other than the first floor (No in S304), the equipment provided in the car 3 is not flooded. In such a case, the control unit 24 causes the car 3 to travel to a predetermined evacuation floor (for example, a predetermined floor above the submerged floor, the top floor, etc.). When stopping the car 3 on the evacuation floor, the control unit 24 stops the elevator after the door opening (closing) operation (S305).

  When the car 3 is stopped on the first floor (Yes in S304), the evacuee is about to be put on the car 3. When the tsunami reaches the building while the car 3 is stopped on the first floor, the submersion sensor 18a of the car 3 detects the submergence as soon as possible. When the submersion sensor 18a detects submergence, a predetermined car device (for example, a device installed in the lower part of the car 3 (a car device other than the car operation panel 33 and the SDE switch 38)) is electrically connected from the control panel 13. Blocked. Further, when the submersion sensor 18d-1 of the landing 2 on the first floor detects submersion, the landing equipment on the first floor is electrically disconnected from the control panel 13.

  When the car 3 is stopped on the first floor, the control unit 24 next determines whether or not the wave height is the height h1 and three seconds or more have passed since the car door 5 was opened ( S306). For example, if the submersion sensor 18a of the car 3 detects submergence and the submersion sensor 18b does not detect submergence, the control unit 24 determines that the wave height is the height h1. The control unit 24 determines the door opening time on the first floor based on the stored contents of the storage unit 22.

  When the wave height is the height h1 and the opening time of the car door 5 is 3 seconds or more (Yes in S306), the control unit 24 does not submerge the car operation panel 33 and the car 3 of the evacuation priority person. It is determined that boarding has been completed. In such a case, the control unit 24 closes the car door 5 and causes the car 3 to go straight to the evacuation floor. When the control unit 24 stops the car 3 on the evacuation floor, the control unit 24 stops the elevator after the door opening (closing) operation (S307). The control unit 24 transmits an electrical signal to the lock device 51 when the elevator is stopped. As a result, the lock device 51 is disengaged from the gear 47, and the power of the elevator (control panel 13) is shut off by the function of the power shut-off means 45.

In exclusive driving, the driver is in the car 3. Even if the car door 5 is closed when the evacuation priority person is in the car 3, the driver can assist the evacuation priority person.
In order to notify the driver that the opening time of the car door 5 on the first floor has passed 3 seconds, when the 3 seconds have passed, the close button of the car operation panel 33 is flashed (lighted → flashing). Also good.

  When the car 3 is run (raised) from a state where the lower part of the car 3 is submerged, there is a risk that the equipment provided in the hall 2 on the way gets wet by the water falling from the car 3. For this reason, when making the car 3 go directly to the evacuation floor in S307, the landing equipment on the floor below the evacuation floor may be electrically disconnected from the control panel 13.

  In S306, when the wave height is higher than the height h1, or when the car door 5 is opened for less than 3 seconds (No in S306), the control unit 24 evacuates after placing the evacuation priority person in the car 3. Judge that there is no room on the floor. That is, there is a high possibility that the car operation panel 33 will be submerged before leaving the car 3. In such a case, the control unit 24 immediately stops the elevator while the car 3 is stopped on the first floor (S308). The control unit 24 transmits an electrical signal to the lock device 51 when the elevator is stopped. As a result, the lock device 51 is disengaged from the gear 47, and the power of the elevator (control panel 13) is shut off by the function of the power shut-off means 45. The evacuation priority person and the driver will evacuate using the stairs 6.

  When the car 3 is traveling in S303, the control unit 24 next determines whether or not the car 3 is moving up (the traveling direction of the car 3 is upward) (S309).

  When the traveling direction of the car 3 is upward (Yes in S309), the car 3 is traveling toward the evacuation floor. In such a case, the control unit 24 continues to travel as it is so that the car 3 arrives at the evacuation floor in a short time. When stopping the car 3 on the evacuation floor, the control unit 24 stops the elevator after the door opening (closing) operation (S305).

  When the traveling direction of the car 3 is downward (No in S309), in order to stop the car 3 on the evacuation floor, after the car 3 is temporarily stopped, the traveling direction is reversed and the car 3 is caused to travel again. I must. During the above operation, the car operation panel 33 may be submerged. For this reason, when the traveling direction of the car 3 is downward (No in S309), the control unit 24 stops the car 3 at the nearest floor, performs a door opening (closing) operation, and then stops the elevator (S310). .

  Next, the operation of the evacuees after evacuating to the rooftop 8 will be specifically described with reference to FIGS. FIG. 23 to FIG. 26 are diagrams for explaining the operation of the evacuees after evacuating to the rooftop.

  When the process shown in S109 of FIG. 12 is performed, the evacuees can go out to the rooftop 8. The evacuees who have left the rooftop 8 first take out the life jacket 58 from the evacuation equipment box 55 and wear it. Next, the evacuee hangs the hook 66 on the support 15 and connects the life jacket 58 to the support 15 (see FIG. 23).

  If the actual wave height of the tsunami is higher than that of the building, the evacuees will float due to the buoyancy of the life jacket 58 and float on the surface of the water. When the evacuees leave the building roof 8, the wire 65 is fed from the reel 64. Since the hook 66 is hung on the support 15, the evacuees are locked in the building (see FIG. 24).

  When a large floating object hits the refugee, the refugee removes the hook 63 from the reel 64. In such a case, the evacuees are temporarily swept away by the tsunami (see FIG. 25). When arriving at another building after being swept away by the tsunami, the refugee hooks the hook 63 on the fence of the building and fixes itself to the building (see FIG. 26). A mobile phone 59 is in the pocket of the life jacket 58. The mobile phone 59 continues to send location information. The evacuees can use the mobile phone 59 to have a conversation. For this reason, it can prevent that an evacuee is missing.

  Next, the operation after the tsunami warning is canceled will be specifically described with reference to FIG. FIG. 27 is a flowchart showing the operation of the elevator apparatus according to Embodiment 1 of the present invention.

  After stopping the elevator at time t3, the control unit 24 determines whether or not the tsunami warning is released (S401). When information indicating that the tsunami warning is canceled is received from, for example, the Japan Meteorological Agency 19 or the information center 20, and the end of the tsunami is detected, the control unit 24 next determines whether or not the landing 2 is submerged ( S402). When the hall 2 is submerged by the tsunami, the submergence sensor 18d detects the submersion. If no landing 2 is flooded, the control unit 24 returns the elevator to normal operation (S403).

  When any landing 2 is submerged (S402), the control unit 24 next determines whether or not the car 3 is submerged (S404). When the car 3 is submerged by the tsunami, the submergence sensor 18a detects the submergence. If the car 3 is flooded when the tsunami arrives, the control unit 24 continues the operation stop of the elevator (S405).

  If any of the landings 2 is submerged, but the car 3 is not submerged (No in S404), the control unit 24 prohibits the operation of the elevator (running of the car 3), but uses the car 3 as an evacuation site. Provide (S406). In such a case, the control unit 24 opens the car door 5 (and the landing door 4). In addition, the control unit 24 displays on the display 27 of the hall 2 that the car 3 can be evacuated. FIG. 28 is a diagram for explaining information provided to evacuees. FIG. 28 shows a display example of the display 27 in S406. The evacuees who have seen the display on the display 27 evacuate temporarily in the car 3. The evacuees can contact the information center 20 using the intercom 39.

  With the elevator device having the above-described configuration, when the occurrence of a tsunami is expected, the elevator can be appropriately controlled according to the predicted tsunami arrival time and the predicted tsunami height. When the control panel 13 can communicate with the Japan Meteorological Agency 19 and the information center 20, appropriate control can be performed based on the tsunami warning and communication information. Even if the control panel 13 cannot communicate with the Japan Meteorological Agency 19 or the information center 20, it is possible to acquire quasi-communication information from evacuees or the like and appropriately specify the predicted tsunami arrival time and the predicted tsunami wave height. it can.

  In the tsunami evacuation control operation, the exclusive operation and the priority operation are performed, so that the evacuation priority person can be evacuated with priority. In priority operation, general evacuees can evacuate using an elevator.

With this elevator apparatus, when the tsunami reaches the building earlier than the predicted tsunami arrival time, it is possible to perform appropriate control giving priority to evacuation over the protection of equipment.
When the landing 2 or the car 3 is submerged, the landing equipment or the car device is disconnected from the control panel 13. Even if the tsunami reaches the building, there is no possibility that the circuit in the control panel 13 is affected by the flooded floor (electric shock, leakage, short circuit, etc.). When the water surface reaches the vicinity of the third floor, the float 53 floats, and the power source of the control panel 13 can be reliably shut off by a physical action.

  Since the roof 8 is provided with the evacuation equipment box 55 in which the life jacket 58 is stored, even if a tsunami higher than the building comes, the refugee can drift on the water surface. The evacuees can wait for rescue using the mobile phone 59, the reel 61, and the like.

  If the car 3 is not flooded after the tsunami ends, the car 3 is provided as an evacuation site. The evacuees can contact the information center 20 using the interphone 39 in the car 3.

Embodiment 2. FIG.
FIG. 29 is a side view showing an elevator apparatus according to Embodiment 2 of the present invention. FIG. 30 is a front view showing the hall on the top floor of the elevator apparatus according to Embodiment 2 of the present invention.

In the elevator apparatus shown in FIG. 29, the control panel 13 and the charging confirmation panel 14 are provided in the pit portion of the hoistway 1. Since there is no need to install the machine room 12 above the hoistway 1, the evacuation equipment box 55 is provided, for example, at the landing 2 on the top floor. The hall 2 on the floor other than the top floor has the same configuration as shown in FIG.
Other configurations are the same as the configurations disclosed in the first embodiment.

Next, the operation of the elevator apparatus having the above configuration will be described with reference to FIG.
FIG. 31 is a flowchart showing the operation of the elevator apparatus according to Embodiment 1 of the present invention.

  The operations shown in S501 and S502 of FIG. 31 are the same as the operations shown in S101 and S102 of FIG. When the predicted tsunami arrival time and the predicted tsunami height are stored in the storage unit 22, the calculation unit 23 calculates a floor (submerged floor) that is submerged when the tsunami arrives, based on the storage content of the storage unit 22. . Information about the submerged floor calculated by the calculation unit 23 is displayed on the display 27 of each hall 2 (S503).

  When it is determined that a part or all of the building is submerged as a result of the calculation by the calculation unit 23, the control unit 24 immediately starts a dedicated operation and stops the elevator as soon as possible.
