The boarding / alighting determination unit 215 also determines whether or not the wheelchair user and other occupants have disembarked from the car 2 based on the output of the phototube sensor 28.

The door open / close control unit 214 controls the opening / closing of the door 29 for opening / closing the car 2. Specifically, when the car 2 stops on an arbitrary floor, the door 29 is opened. Further, the door 29 is closed when a predetermined time has elapsed after the door 29 is opened. The door open / close control unit 214 also opens / closes the door when the open / close button 23 is operated by the occupant. The door open / close control unit 214 also controls to lengthen the door opening time, which is the time when the door 29 is open when the door is opened, and the door 29 is closed, according to the wheelchair user getting in and out of the car 2. Control to slow down the door closing speed, which is the speed at which the door closes. The details of the control for lengthening the door opening time and the control for slowing the door closing speed will be described later.

On the other hand, as shown in FIGS. 1 and 4, the floor control device 3 includes a floor communication device 31, a general floor call button 32, a wheelchair floor call button 33, a floor display unit 34, and a floor speaker 35. I have.

The general floor call button 32 is a button installed at the elevator landing on each floor to register a "general floor call" for calling the ascending or descending car 2. By pressing the general floor call button 32, the floor can be stopped.

The wheelchair floor call button 33 is installed at the elevator platform on each floor and is a button for registering a "wheelchair floor call" for calling a wheelchair car. By pressing the wheelchair floor call button 33, the wheelchair car 2 can be stopped on the floor.

The floor display unit 34 is installed at the elevator landing on each floor, and displays the floor on which the current car 2 is located, arrows indicating ascending / descending, and the like.

The floor speaker 35 outputs information to be notified to the occupants waiting at the elevator landing by voice.

Further, as shown in FIG. 4, the elevator landing on each floor is provided with a door 36 that opens and closes when the occupant goes up and down.

On the other hand, the main control device 1 shown in FIG. 1 includes an operation control unit 11 and a communication unit 12. The main control device 1 can be configured as an integrated computer including, for example, a central processing unit (CPU) and storage means such as a RAM, a ROM, and a hard disk.

The communication unit 12 communicates with the car control device 21 and each floor control device 3 (3-1 to 3-N) by wire or wirelessly.

The operation control unit 11 comprehensively controls the ascent / descent of the car 2 and the stoppage on each floor. Specifically, when the general car call button 24 is pressed and the general car call is registered, the operation control unit 11 controls to stop the car 2 on the registered floor. The operation control unit 11 also controls that when the wheelchair car call button 25 is pressed and the wheelchair car call is registered, the wheelchair car 2 is stopped on the registered floor.

Next, a wheelchair user's boarding / alighting determination by the boarding / alighting determination unit 215, and control for changing the door opening time and the door closing speed of the door 29 by the door opening / closing control unit 214 will be described. The boarding / alighting determination unit 215 determines boarding / alighting of a wheelchair user based on the output signal of the phototube sensor 28.

FIG. 5 is a timing chart showing on / off signals output from the phototube sensor 28. The phototube sensor 28 outputs an on signal when the light projected between the pair of sensors is blocked, and outputs an off signal when the light passes through. FIG. 5A shows an on / off signal when a wheelchair user gets on and off, and FIG. 5B shows an on / off signal when a wheelchair user does not get on and off.

When a general occupant gets in the car 2 or gets off the car 2, the signal output from the phototube sensor 28 is intermittently intermittent as shown in FIG. 5 (b). It is a signal that is repeatedly turned on and off. On the other hand, when the wheelchair user gets on the car 2 or gets off from the car 2, the signal output from the phototube sensor 28 has a long on-time as shown in FIG. 5A. Therefore, the boarding / alighting determination unit 215 determines that the wheelchair user has boarded the car 2 and that the wheelchair user has disembarked from the car 2 based on the on / off signal output from the phototube sensor 28. It becomes possible to do. Specifically, when the on-time of the output signal of the phototube sensor 28 exceeds a preset threshold time, it is determined that the wheelchair user has boarded or disembarked.

When the door open / close control unit 214 detects that a wheelchair user has boarded the car 2, the door opening time of the door 29 (see FIGS. 2 and 3) when the wheelchair user gets on and off , And control to change the door closing speed.

[Operation of this embodiment]
Hereinafter, the operation of the elevator control system according to the present embodiment will be described with reference to the flowcharts shown in FIGS. 6 to 9.

First, in step S11 of FIG. 6, the car control device 21 acquires the output signal of the phototube sensor 28 when a waiting occupant gets on the car 2 on the floor where the car 2 is stopped. ..

In step S12, the boarding / alighting determination unit 215 determines whether or not the wheelchair user P (see FIG. 2) has boarded the car 2 based on the output signal of the phototube sensor 28. When the wheelchair user P gets in the car 2, as shown in FIG. 5A, the on-time of the output signal of the phototube sensor 28 becomes longer than usual. Therefore, the boarding of the wheelchair user P can be detected based on this output signal.

In step S13, if it is determined that the wheelchair user P is in the car 2, the process proceeds to (S13; YES) step S14, and if not, the process proceeds to (S13; NO) step S16. ..

In step S14, the wheelchair call process is performed after the wheelchair user has boarded the car 2. Details will be described later with reference to FIG. 7.

In step S15, the wheelchair user's disembarkation determination process is performed. Details will be described later with reference to FIG.

In step S16, the wheelchair user's non-boarding determination process is performed. Details will be described later with reference to FIG.

FIG. 7 is a flowchart showing the car calling process after the wheelchair user gets on the vehicle shown in step S14 of FIG.

In step S21 of FIG. 7, the car control device 21 determines whether or not the wheelchair car call is newly registered. If it is registered (S21; YES), the process proceeds to step S22, otherwise (S21; NO), the process proceeds to step S24.

In step S22, the car control device 21 determines whether or not another wheelchair call is already registered in addition to the newly registered wheelchair call. If it is registered (S22; YES), the process proceeds to step S23, otherwise (S22; NO), the process proceeds to step S25.

In step S23, the car control device 21 carries out a process of changing another wheelchair car call to a general car call. That is, the fact that the wheelchair user P got in the wheelchair 2 and then the wheelchair car call was newly registered is presumed to mean that the wheelchair user P registered the wheelchair car call.

Therefore, it is presumed that other wheelchair car calls that have already been registered are registered by a general occupant pressing the wheelchair car call button 25. Therefore, it is determined that the other wheelchair call is not registered by the wheelchair user P, and a process of changing to a general wheelchair call is carried out. After that, the process proceeds to step S25.

On the other hand, if the wheelchair call is not newly registered in the process of step S21 (S21; NO), in step S24, the operation control unit 11 is the general car call and the wheelchair registered at that time. Change all car calls to wheelchair car calls. In other words, the fact that the wheelchair car call was not registered after the wheelchair user P got on the wheelchair 2 suggests that the general car call has already been registered on the floor where the wheelchair user P gets off. Will be done. In this case, the wheelchair user P cannot determine on which floor to get off, so all the car calls are changed to wheelchair car calls.

In step S25, the door open / close control unit 214 controls the floor registered as a wheelchair car to lengthen the door opening time and slow down the door closing speed. Therefore, the wheelchair user P who got on the car 2 gets on the door 29 because the door opening time becomes longer than usual and the door closing speed becomes slower when getting off the car 2. You can get off safely from the car 2.

FIG. 8 is a flowchart showing the wheelchair user disembarkation determination process shown in step S15 of FIG.

In step S31, the boarding / alighting determination unit 215 determines whether or not the occupant is getting off from the car 2 based on the output signal of the phototube sensor 28. When the car 2 is stopped by a general car call or a wheelchair car call, and the phototube sensor 28 detects the movement of the occupant, it is determined that the occupant is getting off on this floor.

In steps S32 and S33, the boarding / alighting determination unit 215 determines whether or not the occupant who got off is a wheelchair user P based on the output signal of the phototube sensor 28, as shown in FIG. If it is determined that the wheelchair user P has disembarked (S33; YES), the process proceeds to step S34, and if not (S33; NO), this process ends.

In step S34, the car control device 21 changes all the wheelchair calls registered at that time to general car calls. That is, the fact that the wheelchair user P got off from the car 2 means that all the wheelchair car calls registered at that time are unnecessary, so the wheelchair call is changed to a general car call. That is, if the wheelchair user P gets off the wheelchair 2 after changing all the car calls to wheelchair car calls in the process of step S24 of FIG. 7, the wheelchair user P is subsequently registered as a wheelchair car call. There is no need. Therefore, by changing the wheelchair car call to a general car call, it is possible to avoid unnecessarily lengthening the door opening time of the door 29 or slowing down the door closing speed. After that, this process ends.

FIG. 9 is a flowchart showing the wheelchair user non-ride determination process shown in step S16 of FIG. This process is the process shown in step S13 of FIG. 6, and is executed when it is determined that the wheelchair user is not in the car 2.

First, in step S41, the car control device 21 determines whether or not a new wheelchair car call has been registered. If it is registered (S41; YES), otherwise (S41; NO), this process is terminated.

In step S42, the car control device 21 changes the newly registered wheelchair car call to a general car call. That is, it is presumed that the fact that the wheelchair call is registered even though the wheelchair user P is not on board means that a general occupant has pressed the wheelchair call button 25. In such a case, it is not necessary to register the wheelchair call, so change it to a general car call.

In step S43, the voice output control unit 213 announces in the car 2 that the wheelchair car call has been changed to a general car call. That is, the speaker 27 in the car shown in FIG. 1 announces by voice that the wheelchair car call has been changed to the general car call, and informs the occupants in the car 2. After that, this process ends.

[Effect of this embodiment]
In this way, in the elevator system according to the present embodiment, if it is detected by the phototube sensor 28 that the wheelchair user has boarded the wheelchair 2, and then the wheelchair call is not registered, the general car call is registered. For all floors, control is performed to lengthen the door opening time, which is the time when the door 29 for opening and closing the wheelchair is open, and control to slow down the door closing speed, which is the speed at which the door 29 is closed. ..

Therefore, when the wheelchair user P gets off from the car 2, the door opening time becomes long and the door closing speed becomes slow, so that the wheelchair user P can get off safely and with a margin.

In the present embodiment, an example of executing both a control for lengthening the door opening time and a control for slowing the door closing speed has been described, but the present invention is not limited to this, and at least one of the controls is controlled. May be executed.

If a wheelchair car call is registered after the wheelchair user P gets in the wheelchair 2, all wheelchair car calls other than this wheelchair car call are changed to a general wheelchair call. For this reason, it is possible to prevent the wheelchair call from being registered unnecessarily, and even though the wheelchair user does not get off, the door 29 has a longer door opening time and a slower door closing speed. It is possible to avoid problems such as long downtime on the floor.

Further, after changing all the general car calls to wheelchair calls, when the disembarkation of the wheelchair user is detected, the wheelchair call registered after that is changed to the general car call. Therefore, even though the wheelchair user has disembarked, there is a problem that the door opening time becomes longer on the subsequent stop floor and the door closing speed becomes slower, so that the stop time on the floor becomes longer. Can be avoided.

In addition, if the wheelchair user's boarding is not detected and then a wheelchair car call occurs, it is presumed that this wheelchair car call is due to a general occupant pressing the wheelchair car call button 25. , Change to a general wheelchair. Therefore, it is possible to avoid the problem that the door opening time of the door 29 becomes long and the door closing speed becomes slow on the subsequent stop floor, so that the stop time on the floor becomes long.

Further, since the change of the wheelchair car call to the general car call is announced to the occupants in the car 2, the occupants can recognize the change.

Although some embodiments of the present invention have been described above, these embodiments are presented as examples and are not intended to limit the scope of the invention. These novel embodiments can be implemented in various other embodiments, and various omissions, replacements, and changes can be made without departing from the gist of the invention.
