Description

  The present invention relates to an elevator control device.

  In an elevator, there is a case where a control called service cut for restricting service to a specific floor is performed. With this service cut control, a normal destination floor button operation in the car makes it impossible to perform call registration for a specific floor that is the target of the service cut (hereinafter, this floor is referred to as a “service cut floor”). This is what is controlled. Further, when the car is stopped at the service cut floor for some reason, the door opening is restricted even if the door opening button in the car is operated.

  The service cut control is performed, for example, in order to cope with security problems such as preventing an unauthorized person from entering a floor where entry of unauthorized persons is restricted. In this case, the floor that imposes security entry restrictions is set as the service cut floor. When using this floor, authentication with a personal identification number or an ID card is performed. Only when this authentication is successful, the destination floor call registration and door opening to the floor are permitted.

  In this way, when service cut control is performed from the viewpoint of security, there is a possibility that the car may stop at the service cut floor even though the authentication is not successful (authentication is not performed). . More specifically, the case where there is such a possibility is, for example, when the car is put on standby at an appropriate floor in order to improve driving efficiency in a state where call registration is not made. In some cases, the service cut floor is selected and the car is automatically driven on the service cut floor. In addition, when the elevator is set to be on the service cut floor at a specific time by a timer, it is switched to the service cut floor while the car is running, or the hall assigned to a certain unit in the group management control elevator It is also possible that the call registration is changed to another unit.

  If the car stops on the service cut floor even though the above authentication is not successful, there is a possibility that there is a user in the car, so as described above, authentication is performed to maintain security. Unless it succeeds, door opening on the service cut floor is controlled. Therefore, there is a possibility that the user is trapped in the car.

  Therefore, the conventional elevator control device performs such service cut control, detects that the car is waiting on the service cut floor, and operates the door open button in the car. When it is detected that the vehicle has been operated, a vehicle is known that travels to a specific floor (for example, see Patent Document 1). As this specific floor, the first floor above the ground and the manager room floor are adopted. The specific floor is preferably a floor other than the service cut floor. In addition, when it is detected that the car is waiting on the service cut floor and it is detected that the door opening button in the car is operated, a predetermined notification is given to the user in the car. What is performed is also known (see, for example, Patent Document 2).

  Then, in the elevator control device that performs the conventional service cut control, when all floors are set as service cut floors, the car is forwarded to a predetermined floor such as the entrance floor or a floor with guards. (For example, see Patent Document 3), and when all floors are set as service cut floors, only a destination floor call registration to a specific floor is valid (for example, Patent Documents) 4).

  In addition, in elevators that do not perform service cut control, there is a user in the car after a certain period of time has elapsed since the car stopped and the door was closed, as a means of preventing users from being trapped in the car. When the vehicle is detected, the vehicle is known to travel to the final door opening level (see, for example, Patent Document 5).

Japanese Patent No. 4375138 JP 2006-219222 A Japanese Patent Laid-Open No. 04-153168 Japanese Patent Laid-Open No. 04-201962 Japanese Patent Laid-Open No. 06-271224

  Thus, the conventional elevator control devices shown in Patent Document 1 and Patent Document 2 are used when the car is waiting on the service cut floor and the door opening button in the car is operated. The car is intended to run to a floor other than the service cut floor. However, in such a conventional elevator control device, if all floors are set as service cut floors, the car cannot be moved to a floor other than the service cut floors.

  And when all the floors are set as service cut floors, there is a problem that security may be lowered when traveling on a specific floor such as the first floor above ground. In other words, after getting in the car and waiting for the car to stop on the service cut floor and operating the door opening button, the person who tries to make an unauthorized intrusion that the car will run to the specific floor and open the door If it is understood, it will be meaningless to set the service cut for this specific floor. In addition, since there are buildings where the manager room is not provided, the specific floor cannot always be set as the floor where the manager room is located, and in this respect, there is a possibility that security may be lowered.

  In Patent Document 3 and Patent Document 4, when all floors are set as service cut floors, the car is caused to travel to a specific floor set in advance. In such a conventional elevator control device, when all floors are set as service cut floors, as described above, if the car is made to wait on an appropriate floor to improve driving efficiency, It must be a service cut floor. Then, since the car is caused to travel to a specific floor, there is a problem that the car cannot be waited on an appropriate standby floor in order to improve driving efficiency.

  Moreover, what is described in Patent Document 5 is irrelevant to the service cut control, and there is a problem that no consideration is given to maintaining the security of the building during the service cut control.

  The present invention has been made to solve such a problem, and it is possible to make the service cut floor a standby floor in order to improve driving efficiency, and to maintain the security of the building. It is an object of the present invention to provide an elevator control device that can prevent a user from being trapped in a car when the car is stopped.

  In the elevator control device according to the present invention, the door opening restriction floor setting means for setting an arbitrary floor as a door opening restriction floor for restricting the elevator car from being opened, and the car is the door A door opening limit floor door closing stop detecting means for detecting that the vehicle is stopped when the door is closed on the door opening limit floor, and a door opening operation performed by a user in the car provided in the car. A door opening operation device, a door opening operation detecting means for detecting that the door opening operation has been performed on the door opening operation device, and a floor at which the car was last stopped and opened. The door is stored in a state where it is detected that the car is closed on the door opening restricted floor and stopped by the door opening restricted floor door closing stop detecting means. With respect to the door opening operation device by the opening operation detection means Control that causes the car to travel to the final door opening floor stored in the final door opening storage means and to open the door at the final door opening floor when it is detected that a door opening operation has been performed. Means.

  In the elevator control device according to the present invention, the service cut floor can be used as a standby floor in order to improve driving efficiency, and the car can be stopped when the car stops on the service cut floor while maintaining the security of the building. There is an effect that it is possible to prevent users from being trapped in the car.

In FIG. 1, reference numeral 1 denotes an elevator control device body that controls the overall operation of the elevator. In the elevator hoistway (not shown), a car (not shown) that loads and carries users and the like under the control of the control device main body 1 is disposed so as to be movable up and down.

In this car, a door opening operation device 2, a car guide device 3, and a car destination registration device 4 are provided.
The door opening operation device 2 is for opening a car door that opens and closes a doorway of the car when operated by a user in the car. Information relating to the operation performed on the door opening operation device 2 is transmitted to the control device main body 1 as door opening operation information.

The in-car guidance device 3 is for guiding various information related to the operation status of the elevator such as the destination floor of the car and the current position to the users in the car. The in-car guide device 3 guides the users in the car to the destination floor and the like based on the destination guide command transmitted from the control device main body 1.
The in-car destination registration device 4 is used for registering a call to a destination floor desired by the user when operated by a user in the car. Information relating to operations performed on the car destination registration device 4 is transmitted to the control device main body 1 as destination registration information.
The car is also provided with a door control device (not shown) for controlling the opening / closing operation of the car door provided in the car.

The control device main body 1 includes a door opening operation detection means 5, a drive control means 6, a service cut floor setting means 7, a service cut floor door close / stop detection means 8, and a final door opening floor storage means 9.
The door opening operation detection means 5 detects whether or not the door opening operation device 2 has been opened based on the door opening operation information output from the door opening operation device 2. When the door opening operation detecting means 5 detects that the door opening operation has been performed on the door opening operation device 2, door opening operation detection information is output to the drive control means 6.

  The drive control means 6 controls the driving of the car by controlling the operation of a hoisting machine (not shown), which is a driving machine that drives the raising and lowering of the car. And based on the door open operation detection information etc. which are output from the door open operation detection means 5, a door open command and a door close command are output to the door control apparatus of a car, and the opening / closing of a car door is also controlled. The drive control means 6 acquires the current stop floor of the car and outputs it as car stop floor information, acquires the open / close state of the car door, and outputs it as door open / close information.

  The service cut floor setting means 7 sets an arbitrary floor of the building as a service cut floor that is a floor to be excluded from the service target of the elevator. This service cut floor setting means 7 holds service cut floor information indicating which floor is set as the service cut floor among the floors of the building where the elevator is set. In addition, since the service cut floor is excluded from the service target of the elevator, even if the car stops on this floor, the door opening is controlled. Therefore, in this sense, it can also be called a door opening limit floor. When the service cut floor is a door opening restriction floor, the service cut floor setting means 7 corresponds to the door opening restriction floor setting means, and the service cut floor door closing stop detection means 8 corresponds to the door opening restriction floor closing stop detection means. Will do.

  The service cut floor door close / stop detection means 8 is configured to provide service to the car based on the car stop floor information and door opening / closing information output from the drive control means 6 and the service cut floor information output from the service cut floor setting means 7. It is detected that the car is stopped on the cut floor and the car door is closed. That is, if the car stop floor is the service cut floor and the car is in the door closed state, the service cut floor door closed stop state is detected. When the service cut floor closing stop state is detected, the service cut door closing stop detection unit 8 outputs service cut floor closing detection information to the drive control unit 6.

  Based on the car stop floor information and door opening / closing information output from the drive control means 6, the final door opening storage means 9 stores the floor at which the car was last stopped and opened. The final door opening storage means 9 stores the car stop floor at that time as the final door opening floor when the car is stopped on the floor and is in the door open state. If the car is running or is in a door-closed state, the last door opening level stored at that time is kept as it is.

FIG. 2 shows an in-car operation panel installed in the elevator car. That is, reference numeral 10 denotes an in-car operation panel installed in the car. The in-car operation panel 10 includes a door opening button 11, a door closing button 12, a destination floor registration button 13, a guidance display device 14, and a voice guidance device 15.
The door opening button 11 constitutes a part of the door opening operation device 2, and is used to open the car door when a user in the car presses it. When the door opening button 11 is pressed, the door opening operation device 2 outputs door opening operation information to the control device main body 1. The door closing button 12 is used for closing a car door when a user in the car presses the door button.

  The destination floor registration button 13 constitutes a part of the in-car destination registration device 4, and a car destination floor to a floor desired by the user as a destination when the user in the car depresses it. This is for call registration. The destination floor registration button 13 is composed of a plurality of buttons provided corresponding to each floor of the building. The user presses the destination floor registration button 13 corresponding to his / her predetermined destination floor. When the destination floor registration button 13 is pressed, the in-car destination registration device 4 outputs to the control device body 1 destination registration information in which the floor corresponding to the pressed button is the destination floor. And the control apparatus main body 1 registers a destination floor call based on this destination registration information.

  Further, each of the destination floor registration buttons 13 has a built-in lighting means such as an LED. The control device main body 1 outputs a destination button lighting command to the in-car destination registration device 4 based on the destination floor call registration status, the elevator operation status, and the like. The car destination registration device 4 lights or blinks the lighting means of each destination floor registration button 13 based on the destination button lighting command.

  The guidance display device 14 and the voice guidance device 15 constitute part of the car guidance device 3. The guidance display device 14 is composed of, for example, a liquid crystal display or an LED display. The guidance display device 14 displays a message made up of numbers, characters, figures, etc. to the users in the car. In addition, the voice guidance device 15 has a speaker and can announce a voice message or the like to a user in the car. The in-car guidance device 3 displays a message on the guidance display device 14 based on a destination guidance command or the like output from the control device main body 1, and makes an announcement by the voice guidance device 15. In this way, necessary guidance is provided to users in the car.

In this embodiment, the elevator control device determines whether to start the rescue operation according to a series of flows shown in FIG.
First, in step S <b> 1, the drive control means 6 of the control device main body 1 confirms whether or not the service cut floor closing detection information is output from the service cut floor closing detection means 8. In other words, it is confirmed whether or not the car is stopped at the service cut floor and the door closed state (service cut floor door closed stop state) is detected. And when this service cut floor closing stop state is detected by this step S1, it progresses to step S2. On the other hand, when the service cut floor closing stop state is not detected, the process proceeds to step S4 and the operation flow ends.

  In step S <b> 2, the drive control unit 6 confirms whether or not the door opening operation detection information is output from the door opening operation detection unit 5. This confirms whether or not the door opening operation detecting means 5 has detected that the door opening button 11 of the door opening operation device 2 has been operated. If an operation on the door open button 11 is detected in step S2, the process proceeds to step S3. On the other hand, when the operation with respect to the door opening button 11 is not detected, the process proceeds to step S4 and the operation flow ends.

  When an operation on the door opening button 11 is detected in a state where the service cut floor door closing stop state is detected, the drive control means 6 starts the rescue operation in step S3. At this time, it is detected that the door opening button 11 is operated, but the door opening command is not output (the car door is not opened). Then, the process proceeds to step S4, and a series of operation flow ends.

FIG. 4 shows the operation of the elevator control device after the rescue operation is started. That is, when the rescue operation is started in step S3 in FIG. 3, first, in step S11 in FIG. 4, the user in the car is guided to travel to the final door opening level. In step S <b> 11, first, the drive control unit 6 acquires final door opening information from the final door opening storage unit 9. Then, the drive control means 6 outputs a destination guidance command to the car guidance device 3 based on the final door opening information. Based on this destination guidance command, the in-car guidance device 3 uses the guidance display device 14 and the voice guidance device 15 to indicate that the floor where the car is currently stopped cannot be opened for security reasons, and the final Travel to the door opening level and inform the passengers in the car that the door will open.
At this time, the drive control means 6 may output a destination button lighting command to the car destination registration device 4 so as to light the destination floor registration button 13 corresponding to the final door opening floor.

Next, proceeding to step S12, the drive control means 6 causes the car to travel to the final door opening level. In subsequent step S13, the drive control means 6 confirms whether or not the car has arrived at the final door opening level. If it is confirmed in step S13 that the car has arrived at the final door opening level, the process proceeds to step S14. In step S14, the drive control means 6 outputs a door opening command to the car door control device to open the car door. Then, the process proceeds to step S15, and a series of operation flow ends.
On the other hand, if it is not confirmed in step S13 that the car has arrived at the final door opening level, the process returns to step S12, and this step S12 is performed until it is confirmed that the car has arrived at the final door opening level. Is repeated.

  The fact that the door opening button operation is detected when the car is stopped on the service cut floor (the door opening restriction floor) is considered to indicate that the user is in the car and wants to get off. Therefore, in order to rescue this user, it is necessary to open the door at an appropriate floor and get off the vehicle. The elevator control system configured as described above allows passengers to get on and off the floor that stops to rescue in order to prevent security degradation even when all floors are service cut floors (door opening restricted floors) It is to be the floor that was. Specifically, by memorizing the floor at which the car was last stopped and opened, the floor where the passengers in the car were able to get on and off when the door open button was operated It is possible to get off the vehicle.

  For this reason, the service cut floor can be used as a standby floor in order to improve driving efficiency, and it can be used in the car when the car stops on the service cut floor while maintaining the security of the building. Person confinement can be prevented.

  Further, if the elevator is in a normal state, the car will not run suddenly when the door open button is operated. Therefore, as described here, when the door opening button operation is detected, automatically running the car is an operation different from the user's intention and may cause anxiety to the user. Therefore, the user can understand the situation and operation by informing the user in the car before the car travels that the car will be driven to the final door opening level. Anxiety that a person has can be reduced.

Embodiment 2. FIG.
FIG. 5 relates to Embodiment 2 of the present invention.
In the first embodiment described above, after the rescue operation is started, the car is automatically driven to the final door opening level. On the other hand, in the second embodiment described here, after the rescue operation is started, the destination floor registration button corresponding to the final door opening flashes, and the user in the car corresponds to the final door opening. The user is prompted to press the destination floor registration button.

  That is, in the second embodiment, the configuration of the elevator control device is the same as that of the first embodiment (therefore, detailed description thereof is omitted). And the operation | movement of the control apparatus of the elevator after a rescue operation start differs from Embodiment 1, and it becomes what is shown in FIG.

  That is, when the rescue operation is started, first, in step S21 of FIG. 5, the drive control means 6 blinks the destination floor registration button 13 corresponding to the final door opening floor. The flashing of the destination floor registration button 13 in step S21 is performed as follows. First, the drive control means 6 acquires the final door opening information from the final door opening storage means 9. And the drive control means 6 blinks the destination floor registration button 13 corresponding to the last door opening floor based on this last door opening floor information. This blinking operation can be realized, for example, if the drive control means 6 intermittently outputs a destination button lighting command to the car destination registration device 4.

  Then, the process proceeds to step S22, and guidance is provided to prompt the user in the car to operate the blinking destination floor registration button 13. In this step S22, first, the drive control means 6 outputs a destination guidance command to the car guide device 3 based on the final door opening floor information. Based on the destination guidance command, the in-car guide device 3 indicates that the guidance display device 14 and the voice guidance device 15 cannot open the door for security reasons at the floor where the car is currently stopped, and The user in the car is instructed to prompt the user to operate the flashing destination floor registration button 13.

  In the next step S23, the control device body 1 detects that the destination floor registration button 13 corresponding to the final door opening floor has been pressed based on the destination registration information output from the car destination registration device 4. Confirm whether or not. In step S23, when it is confirmed that pressing of the destination floor registration button 13 corresponding to the last door opening is not detected, the process returns to step S21, and the destination floor registration button corresponding to the last door opening floor is detected. 13 continues to blink. On the other hand, when it is confirmed that pressing of the destination floor registration button 13 corresponding to the final door opening floor is detected, the process proceeds to step S24.

In step S24, the drive control means 6 causes the car to travel to the final door opening floor. In subsequent step S25, the drive control means 6 confirms whether or not the car has arrived at the final door opening level. If it is confirmed in step S25 that the car has arrived at the final door opening level, the process proceeds to step S26. In step S26, the drive control means 6 outputs a door opening command to the car door control device to open the car door. Then, the process proceeds to step S27, and the series of operation flow ends.
On the other hand, if it is not confirmed in step S25 that the car has arrived at the final door opening level, the process returns to step S24, and this step S24 is performed until it is confirmed that the car has arrived at the final door opening level. Is repeated.

  The elevator control device configured as described above does not automatically move the car to the final door opening floor when starting the rescue operation, but the destination floor registration button corresponding to the final door opening floor. By blinking the lighting means, the user is prompted to operate the blinking destination floor registration button. When it is detected that the blinking destination floor registration button has been operated, the car is moved to the final door opening floor and opened at the final door opening floor. Therefore, the user can drive the car to the final door opening floor by an operation similar to the operation for the normal destination floor registration button. For this reason, the user can grasp a situation and operation, and can reduce anxiety that the user has.

Embodiment 3 FIG.
In the first embodiment and the second embodiment described above, the floor at which the car was last stopped and opened is stored as the final door opening. At this time, no special consideration was given to the type of call registration that caused the car to stop at the final door opening. On the other hand, Embodiment 3 described here also considers the type of call registration that caused the car to stop.

  There are two types of call registration here. The first is car destination floor call registration performed by a user in the car operating a destination floor registration button 13 provided in the car which is the car destination registration device 4. The second is hall call registration performed by a user at the hall operating a hall call button provided at the hall of the floor where the car stops.

  The last door opening storage means 9 stores the car stop floor at that time as the last door opening floor when the car is stopped on the floor according to the hall call registration and is in the door open state. To do. And if the car is running or is in a closed state, or if it is stopped on the floor in response to the car destination floor call registration, the last stored at that time Continue to hold the door open. If the floor call registration and the car destination floor call registration are both stopped and the door is open, the car stop floor at that time is stored as the last door open floor. Is done. In other words, a floor that has been stopped only by car destination floor call registration is excluded from the final door opening target.

Therefore, in this embodiment, the floor that has been stopped and opened by the user calling the car by an operation at the landing is an object to be stored as the final door opening. On the other hand, the floor where the car is stopped and opened by only the operation of the user in the car is excluded from the object to be stored as the final door opening.
Other configurations are the same as those in the first or second embodiment, and detailed description thereof is omitted.

  In the elevator control apparatus configured as described above, the final door opening storage means 9 has a floor in which the car is stopped and opened only by an operation on the car destination registration device 4 provided in the car. This is excluded from the object to be stored as the last door opening floor.

  Normally, when using an elevator, the user calls on a landing call button provided at the landing to get on the car that has arrived. Therefore, at the floor that is stopped only by operating the destination floor registration button in the car, there is only a user who gets off the car, and there is a high possibility that there is no user who gets into the car. . Therefore, from the floor where the rescue is performed by excluding the floor where the car is stopped and opened by only the operation on the car destination registration device 4 provided in the car from the object to be stored as the final door opening floor. It is possible to exclude floors that are unlikely to be boarded by users in the car. For this reason, it is possible to maintain the security of the building in a better state.
