Description

The present invention relates to an elevator, and more particularly to an elevator having a plurality of doors in a car.

In recent years, there are elevators that perform disaster control operations in the event of a disaster such as a fire, earthquake, or power outage.

For example, the conventional elevator operating device described in Patent Document 1 drives a car to a preset evacuation floor by disaster control operation when a fire is detected, and opens the door to the car. After letting them close the door, they will be put on standby at the evacuation floor. The elevator of Patent Document 1 is provided with a display device that displays to the outside a state in which a passenger who has been delayed in escaping exists in the car waiting for the door to close. Therefore, when the display device indicates that there are passengers in the car, a worker such as a firefighter on the evacuation floor operates the landing button, or the worker is remote from the monitoring room. By operating the car, the car is opened.

Further, for example, in the conventional elevator control device described in Patent Document 2, when the occurrence of a disaster is detected, the car is driven to the evacuation floor and the door is opened by the disaster control operation. At this time, the elevator control device determines the presence or absence of passengers in the car based on the detection result of the passenger presence detection device. When it is determined that there are no passengers, the elevator control device closes the door. On the other hand, if it is determined that there are passengers, the door closing operation is invalidated.

In recent years, one car having two doors has been developed.

However, in Patent Document 1 and Patent Document 2, an elevator in which a car having such two doors is installed is not considered at all.

Here, suppose that the elevator of Patent Document 1 is provided with a car having two doors, and the car performs evacuation operation. At this time, if the display device indicates that there are passengers in the car, the car will perform any of the following operations by operating the landing button on the evacuation floor or by remote control from the monitoring room. It will be. As a result, there is a problem that the evacuation operation after the control operation cannot be performed smoothly.
(A): When the car is waiting to close, the door to the landing on the side affected by the fire may be opened and smoke or gas may flow into the car.
(B): When the car is running, the car may stop between floors in response to a door opening command. In that case, the evacuated passengers will be trapped in the car. Alternatively, after the car has traveled to the evacuation floor, the door to the landing on the side affected by the fire may be opened.

Further, in Patent Document 2 described above, suppose that the elevator is provided with a car having two doors, and the car is performing evacuation operation. The elevator control device performs a door closing operation when it is determined that there are no passengers, but invalidates the door closing operation when it is determined that there are passengers. Therefore, when a worker such as a firefighter is in the car to guide evacuation, the door cannot be closed. As a result, there is a problem that the evacuation operation after the control operation cannot be performed smoothly.

The present invention has been made to solve such a problem, and to obtain an elevator having at least one car having a plurality of doors and capable of smoothly performing evacuation operation by the car. The purpose.

Similarly, when the landing buttons 6 and 7 are provided on the top floor, only the downward buttons are provided on the landing buttons 6 and 7.

Each of the cars L1, L2 and L4 has one door 11. These doors 11 are provided facing the landing 14. On the other hand, the car L3 has doors 11 and 12 in two directions. In the car L3, the door 11 and the door 12 are arranged at positions facing each other. It is assumed that the car L3 has both doors 11 and 12 on all floors including the evacuation floor. Here, an example is given in which the door 11 and the door 12 are arranged at positions facing each other, but not limited to this case, the door 11 is provided on one surface of the car L3, and the door 12 is provided. , It may be provided on another surface different from the one surface.

Of the two doors 11 and 12 of the car L3, the door 11 is provided on the side facing the landing 14 like the doors 11 of the other cars L1, L2 and L4. In the normal state, the car L3 is operated in the normal operation mode by using the door 11 provided on the side facing the landing 14, like the other cars L1, L2 and L4.

On the other hand, the door 12 of the car L3 is provided facing the landing 15 in the fireproof section of the building. When the operation mode of the car L3 is switched to the evacuation operation mode in the event of a disaster such as a fire, earthquake, or power outage, the car L3 remains in the building using only the door 12 leading to the landing 15 in the fireproof compartment. Evacuate the passengers who are doing the evacuation.

Hereinafter, the operation of the elevator according to the first embodiment will be briefly described. The cars L1, L2, and L4 have two operation modes, a normal operation mode and a disaster control operation mode. On the other hand, the car L3 has three operation modes: a normal operation mode, a disaster control operation mode, and an evacuation operation mode.

Now suppose a fire broke out in the building. The group management device 1 switches the operation modes of all the cars L1 to L4 from the normal operation mode to the disaster control operation mode. As a result, the operation of the cars L1 to L4 becomes a disaster control operation. In the disaster control operation, the cars L1 to L4 travel to the preset evacuation floor, open the door on the evacuation floor, and disembark the passengers in the car. Further, after a certain period of time has passed after the door is opened, the cages L1 to L4 are closed. After that, the cars L1, L2, and L4 stand by in the closed state on the evacuation floor. The evacuation floor is set in advance on any floor, but generally, it is set on the floor where the entrance / exit of the building communicating with the outside is installed.

On the other hand, for the car L3, the group management device 1 further switches the operation mode from the disaster control operation mode to the evacuation operation mode. In addition, the group management device 1 transmits a signal indicating that the mode has been switched to the evacuation operation mode to the management room of the building. As a result, the management room of the building moves to the landing 15 in the fireproof section for the passengers in the building via the announcement device on each floor, and uses the car L3 to evacuate to the outside of the building. Guidance is provided by voice message.

When the operation mode is switched to the evacuation operation mode, the car L3 starts the evacuation operation using only the door 12. During the evacuation operation, the door 11 is maintained in the closed state. In the evacuation operation, the car L3 once travels to the top floor, opens the door 12, and allows passengers at the landing 15 in the fireproof compartment to board. Next, the car L3 descends one by one to the lower floors, and passengers of the landing 15 in the fireproof compartment are boarded on all floors. After that, drive to the evacuation floor and get off the passengers in the car to evacuate.

In the elevator according to the first embodiment, when a worker such as a firefighter or another passenger operates the landing button 6 or the landing button 7, the doors 11 of all the cars L1 to L4 waiting on the floor are opened. To do. This allows workers such as firefighters or other passengers to check if there are any passengers left in the cars L1 to L4. However, if the car L3 is in evacuation operation and the door 12 on the landing 15 side in the fireproof compartment is being used, even if a worker such as a firefighter or another passenger operates the landing button 6 or the landing button 7. , The door 11 of the car L3 does not open.

Next, the internal configuration of the elevator according to the first embodiment will be described with reference to FIG. As shown in FIG. 2, the elevator according to the first embodiment includes a group management device 1, each unit control device 8-1, 8-2, 8-3, 8-4, cars L1 to L4, and each floor. It is configured to have landing buttons 6 and 7 installed in.

The group management device 1 includes a disaster control operation detection unit 2, an all-car door open / close control unit 3, an announcement determination unit 4, and a landing button operation detection unit 5.

On the other hand, each unit control device 8-3 is configured to include a door opening / closing control unit 9-3, an announcement unit 10-3, and a door opening / closing control unit 13-3 during evacuation operation.

Hereinafter, each component of FIG. 2 will be described.

First, the rough operation of the group management device 1 will be described. The group management device 1 controls the operation of all the cars L1, L2, L3, and L4 in the grape via the control devices 8-1, 8-2, 8-3, and 8-4.

Next, each component of the group management device 1 will be described.

The disaster control operation detection unit 2 has a disaster occurrence determination unit that determines whether or not a disaster such as a fire, an earthquake, or a power outage has occurred. The occurrence of a disaster is detected by, for example, the following method. Each sensor such as a fire sensor, an earthquake sensor, and a power failure sensor is provided in advance as a disaster occurrence detection device in the building. In addition, each sensor is provided with a switch or contact that switches ON / OFF when each sensor detects the occurrence of a disaster. When each sensor detects the occurrence of a disaster, these switches or contacts output a disaster control operation signal to the group management device 1 by switching ON / OFF. The disaster occurrence determination unit of the disaster control operation detection unit 2 determines whether or not a disaster has occurred based on the presence or absence of reception of the disaster control operation signal.

Further, when the disaster control operation detection unit 2 determines that a disaster has occurred, the car L1, L2, L3, for each unit control device 8-1, 8-2, 8-3, 8-4. It has a disaster control operation unit that transmits a mode switching command to switch the operation mode of L4 to the disaster control operation mode and controls the cars L1, L2, L3, and L4 to perform disaster control operation.

Further, the disaster control operation detection unit 2 transmits a mode switching command to each unit control device 8-3 so as to switch the operation mode from the disaster control operation mode to the evacuation operation mode after the disaster control operation is performed. The car L3 has an evacuation driving unit that controls the evacuation driving.

In the disaster control operation mode, the all car door opening / closing control unit 3 is the landing button 6 or the landing button based on the information from the landing button operation detection unit 5 when the cars in the group are waiting for the door to close on the evacuation floor. When it is detected that 7 has been operated, a door opening command is output to each of the control devices 8-1, 8-2, 8-3, and 8-4. Even if the operation mode of the car L3 is the evacuation operation mode and the car L3 is in the evacuation operation, the door opening command is issued to all the control devices 8-1, 8-2, 8-3, 8-4. Is output to. At this time, each unit control device 8-3 invalidates the door opening command for the car L3 and maintains the door closed state of the door 11 of the car L3.

When all the cars L1 to L4 start the disaster control operation by the command of the disaster control operation detection unit 2, the announcement determination unit 4 makes all the announcement devices (not shown) installed at the landing 14 on each floor. A pause guidance command is output so as to output a voice message indicating that the cars L1 to L4 have been suspended. An example of a voice message in this case is, for example, "All units 1 to 4 are inactive." The voice message is generated in advance and stored in a memory.

Further, when the landing button 6 or 7 is operated on any floor other than the evacuation floor in the evacuation operation mode, the announcement determination unit 4 makes a landing based on the information from the landing button operation detection unit 5. The cars L1, L2, and L4 are inactive and the car L3 evacuates at the landing 15 in the fireproof compartment with respect to the announcement device (not shown) installed at the landing 14 on the floor where the button 6 or 7 is operated. Output an evacuation guidance command to output a voice message indicating that the vehicle is in operation. An example of a voice message in this case is, for example, "We are currently conducting evacuation operation at Unit 3. If you want to use it, please wait at the landing in the fireproof area." The voice message is generated in advance and stored in a memory.

Further, when the landing button 6 or the landing button 7 is operated on the evacuation floor, the announcement determination unit 4 operates the landing button 6 or the landing button 7 based on the information from the landing button operation detection unit 5. The car L1 or the car L4 is selected as the car closest to the car L3 from the cars adjacent to the car. Then, the announcement determination unit 4 outputs a voice message from the announcement device (not shown) installed in the selected car L1 or car L4 to the effect that the door 11 of the car L3 has stopped opening and will not open. A door opening cancellation guidance command is output so as to do so. An example of a voice message in this case is, for example, "The door of Unit 3 will not open." The voice message is generated in advance and stored in a memory.

In this way, the announcement determination unit 4 determines what kind of voice message is output from which output unit when the landing button operation detection unit 5 detects that the landing button 6 or 7 has been operated. Then, an output determination unit that outputs one of a pause guidance command, an evacuation guidance command, and a door opening stop guidance command to the announcement units 10-1 to 10-4 is configured.

As described above, in the first embodiment, the car L3 has three operation modes: a normal operation mode, a disaster control operation mode, and an evacuation operation mode. Further, the car L3 has a door 11 as a normal operation door used in the normal operation mode and a door 12 as an evacuation door used in the evacuation operation mode. When a disaster occurs, first of all, by disaster control operation, the cars L1 to L4 travel to a preset evacuation floor, disembark passengers, and then stand by for closing the door on the evacuation floor. After that, only the car L3 uses only the door 12 used at the time of evacuation, and the evacuation operation is performed with the door 11 closed. As a result, the evacuation operation after the disaster control operation can be smoothly performed.

Further, in the first embodiment, when the landing button 6 or 7 on the evacuation floor is operated, the announcement determination unit 4 outputs a door opening cancellation guidance command, and the door 11 of the car L3 cancels the door opening. Outputs a voice message stating that the door will not open. Therefore, it is possible to prevent troubles such as a worker such as a firefighter erroneously recognizing that the door 11 of the car L3 cannot be opened and trying to pry open the door. As a result, it is possible to prevent troubles such as unwinding stop due to prying open of the door of the car L3. In addition, since the existing announcement device or display device installed in the landing or the car is used without newly installing another device, the design of the car and the landing is not impaired and the cost is increased. Can be avoided. Further, the announcement determination unit 4 selects the car closest to the car L3 from the operated cars adjacent to the landing button 6 or the landing button 7 based on the information from the landing button operation detection unit 5. Since the voice message is issued from a close position to the person who operates the landing buttons 6 and 7, the audibility of the voice message can be improved.

The landing button operation detection unit 5 detects whether or not the landing buttons 6 or 7 installed on each floor have been operated in the control operation mode and the evacuation operation mode. Further, when the landing button operation detection unit 5 detects that the landing button 6 or 7 has been operated, the information indicating that the operation has been performed, and the installation floor and the installation position of the operated landing buttons 6 and 7 are provided. Information about the above is transmitted to the announcement decision unit 5. Further, in the landing button operation detection unit 5, when the floor on which the landing button 6 or 7 is operated is the evacuation floor, the landing button 6 or 7 is operated on the evacuation floor with respect to the all car door opening / closing control unit 3. Send information indicating that.

The door opening / closing control units 9-1, 9-2, 9-3, and 9-4 are provided in the respective unit control devices 8-1, 8-2, 8-3, and 8-4, respectively. The door opening / closing control units 9-1, 9-2, 9-3, 9-4 receive the door opening command and the door closing command from all the car door opening / closing control units 3 in the group management device 1. During normal operation, the door opening / closing control units 9-1, 9-2, 9-3, and 9-4 perform door opening operations of the cages L1, L2, L3, and L4, respectively, in accordance with the door opening command and the door closing command. And close the door. Further, in the disaster control operation mode, the door opening / closing control units 9-1, 9-2, 9-3, 9-4 open the door when the cars L1 to L4 are waiting for the door to close on the evacuation floor. The door 11 is opened according to the instruction. On the other hand, when the car L3 is in the evacuation operation, the door opening / closing control unit 9-3 invalidates the door opening command and maintains the door closed state even if the door opening / closing command is received.

The announcement units 10-1, 10-2, 10-3, and 10-4 are provided in the respective unit control devices 8-1, 8-2, 8-3, and 8-4, respectively. The announcement units 10-1, 10-2, 10-3, and 10-4 are announcement devices (not shown) provided in the cars L1 to L4 in accordance with the suspension guidance command, the evacuation guidance command, and the door opening stop guidance command. ) Or, an announcement device (not shown) provided on each floor outputs a voice message as a signal to be output. In this way, the announcement units 10-1, 10-2, 10-3, 10-4 and the announcement device are the pause guidance command, the evacuation guidance command, and the door from the announcement determination unit 4 in the group management device 1. It functions as an output unit that outputs a signal to be output to the outside in accordance with any one of the open / stop guidance commands.

Here, a voice message will be described as an example of a signal to be output, but the present invention is not limited to this case. For example, when a display device is installed in an elevator, the display device may be used instead of the announcement device to display a character message on the display screen of the display device. Alternatively, an announcement unit is set up in the remote management room, and the announcement determination unit 4 sends a suspension guidance command, an evacuation guidance command, and a door opening cancellation guidance command to the announcement section of the management room. You may. In that case, the announcement unit of the control room instructs the announcement device or display device installed in the building to output a voice message or a text message.

The door opening / closing control unit 13-3 during evacuation operation is provided in each unit control device 8-3. The door opening / closing control unit 13-3 during evacuation operation controls the opening / closing operation of the door 12 when the car L3 is operating in the evacuation operation mode. The door opening / closing control unit 9-3 in each unit control device 8-3 opens / closes the door 11, whereas the door opening / closing control unit 13-3 during evacuation operation opens and closes the door 12.

Next, the operation of the elevator according to the first embodiment will be described with reference to FIG.

In FIG. 3, four cars L1 to L4 wait for the door to close on the evacuation floor during disaster control operation, then the car L3 switches to the evacuation operation mode and operates using the door 12 on the landing 15 side in the fireproof compartment. Show the case. In FIG. 3, the car L3 departs from the evacuation floor by the evacuation operation after the disaster control operation is performed, and is not on the evacuation floor.

In FIG. 3, first, in step S1, the disaster occurrence determination unit of the disaster control operation detection unit 2 determines that a disaster has occurred by receiving a disaster control operation signal from each switch or contact.

In step S2, the disaster control operation unit of the disaster control operation detection unit 2 changes the operation mode from the normal operation mode to the disaster control operation for each unit control device 8-1, 8-2, 8-3, 8-4. A mode switching command is transmitted to switch to the mode, and the cars L1, L2, L3, and L4 are controlled to perform disaster control operation. As a result, the cars L1 to L4 travel to the evacuation floor by fire control operation. The cars L1 to L4 open the door 11 on the evacuation floor to disembark the passengers in the cars L1 to L4. Further, when a predetermined fixed time elapses after the door is opened, the cars L1 to L4 close the opened door. As a result, all the cars L1 to L4 are in the door closing standby state on the evacuation floor.

In step S3, the evacuation operation unit of the disaster control operation detection unit 2 instructs each unit control device 8-3 to switch the operation mode of the car L3 from the disaster control operation mode to the evacuation operation mode. Is output. As a result, the car L3 switches to the evacuation operation mode, departs from the evacuation floor, and starts the evacuation operation. During the evacuation operation, only the door 12 facing the landing 15 in the fireproof compartment is opened and closed, and the door 11 is kept closed.

In step S4, the landing button operation detection unit 5 in the group management device 1 determines whether or not the landing button 6 has been operated on the evacuation floor. As a result of the determination, if it is determined that the landing button 6 has been operated on the evacuation floor, the process proceeds to step S8. If not, the process proceeds to step S5.

In step S5, the landing button operation detection unit 5 in the group management device 1 determines whether or not the landing button 7 has been operated on the evacuation floor. As a result of the determination, if it is determined that the landing button 7 has been operated on the evacuation floor, the process proceeds to step S6. If not, the process returns to step S4.

In step S6, the door open / close control unit 3 in the group management device 1 outputs a door open command to each of the unit control devices 8-1 to 8-4. Each unit control device 8-1, 8-2, 8-4 operates the door opening operation of the cages L1, L2, L4 by the door opening / closing control units 9-1, 9-2, 9-4. However, since the car L3 is in the evacuation operation, the door 11 cannot be opened, so that each unit control device 8-3 does not respond to the door opening command.

In step S7, the announcement determination unit 4 in the group management device 1 selects a car that issues a voice message indicating that the car L3 has stopped opening the door. That is, the announcement determination unit 4 selects the car L4 as the car closest to the car L3 from the cars adjacent to the operated landing button 7. The announcement determination unit 4 outputs a voice message to the announcement unit 10-4 of each unit control device 8-4 from the announcement device installed in the car L4 to the effect that the car L3 will not open. Outputs a start / stop guidance command. As a result, the announcement unit 10-4 issues the voice message from the announcement device installed in the car L4.

In step S8, the door open / close control unit 3 in the group management device 1 outputs a door open command to each of the unit control devices 8-1 to 8-4. Each unit control device 8-1, 8-2, 8-4 operates the door opening operation of the cages L1, L2, L4 by the door opening / closing control units 9-1, 9-2, 9-4. However, since the car L3 is in the evacuation operation, the door 11 cannot be opened, so that each unit control device 8-3 does not respond to the door opening command.

In step S9, the announcement determination unit 4 in the group management device 1 selects a car that issues a voice message indicating that the car L3 has stopped opening the door. That is, the announcement determination unit 4 selects the car L1 as the car closest to the car L3 from the cars adjacent to the operated landing button 6. The announcement determination unit 4 outputs a door opening cancellation guidance command to the announcement unit 10-1 of each unit control device 8-1 so as to output a voice message indicating that the car L3 will not open the door. As a result, the announcement unit 10-1 issues the voice message from the announcement device installed in the car L1.

As described above, in the elevator according to the first embodiment, when a disaster occurs, the cars L1 to L4 travel to a preset evacuation floor by disaster control operation, disembark passengers, and then evacuate. Wait for the door to close on the floor. Further, only the car L3 has the doors 11 and 12, and the evacuation operation is performed while the door 11 is closed by using only one of the doors 12 used at the time of evacuation. At this time, by operating the landing buttons 6 and 7 on the evacuation floor, the doors 11 of the cars L1, L2 and L4 are opened, and it is confirmed from the outside whether there are any passengers who have been late to escape in the car. Can be done. On the other hand, even if the landing buttons 6 and 7 are operated on the evacuation floor, the door 11 is not opened when the car L3 is in the evacuation operation, so that a firefighter or the like may mistakenly think that the door 11 cannot be opened. There is sex. Therefore, another car L1 or L4 closest to the car L3 issues a voice message indicating that the door 11 of the car L3 has stopped opening. This makes it possible to prevent troubles such as unwinding stop due to prying open by firefighters and the like. As a result, in the elevator according to the first embodiment, disaster control operation and evacuation operation can be smoothly performed.

In the above description, in order to make the explanation easier to understand, the door 11 is used as a normal door and the door 12 is used as an evacuation door, but the use of the door is not particularly limited to normal time and evacuation. .. Further, both doors 11 and 12 may be used at normal times, and the door 12 facing the landing 15 in the fireproof compartment may be used only at the time of evacuation.

In the above-described first embodiment, the group management device 1 and the control devices 8-1, 8-2, 8-3, and 8-4 of each unit are configured to include a controller.
