That is, in the display restriction operation mode, the control device 1 restricts display of the destination floor of the car 103 registered by the destination floor button 119 on the display device 111 of the call registration device 102 of each floor 110.

  Next, an example of a flowchart for controlling the elevator 101 of the control device 1 will be described with reference to FIG. FIG. 4 is a flowchart illustrating an example of control contents of the elevator control device according to the embodiment. Note that the flowchart illustrated in FIG. 4 is repeatedly executed by the control device 1.

  First, the control device 1 is in a normal operation mode. Control device 1 receives a button-on signal indicating that one of registration buttons 112 and 114 of call registration device 102 provided on each floor 110 has been pressed (step ST1). In step ST <b> 1, the control device 1 is registered for call by any one of the call registration devices 102 provided on each floor 110. Then, the control device 1 determines whether or not the call registration is a special call registration registered by pressing one of the registration buttons 112 and 114 and the first special button 113 at the same time (Step S1). ST2). Specifically, the control device 1 determines whether any one of the registration buttons 112 and 114 and the button on signal of the first special button 113 are input simultaneously. When it is determined that either one of the registration buttons 112 and 114 and the button on signal of the first special button 113 are not input simultaneously, the control device 1 determines that it is not special call registration (step ST2: No), and sets the normal operation mode. Maintain (step ST20).

  When determining that either one of the registration buttons 112 and 114 and the button-on signal of the first special button 113 are simultaneously input, the control device 1 determines that the call is a special call registration (step ST2: Yes), and the level of the call registered. The car 103 is moved up and down toward the floor 110. The control device 1 causes the car 103 to land on the call registered floor 110, and opens the open / close door 103a (step ST3). Then, the passenger gets into the car 103. Then, the control device 1 determines whether or not any destination floor button 119 has been pressed within a predetermined time after the opening / closing door 103a is opened, that is, whether or not the destination floor has been registered ( Step ST4). Specifically, the control device 1 determines whether or not a button-on signal of any destination floor button 119 is input within a predetermined time. If it is determined that the button-on signal of any destination floor button 119 is not input within a predetermined time, the control device 1 determines that there is no destination floor registration (step ST4: No), and maintains the normal operation mode. (Step ST20).

  If control device 1 determines that a button-on signal of any destination floor button 119 has been input within a predetermined time, it determines that destination floor registration has occurred (step ST4: Yes), and destination floor registration is either The destination floor button 119 and the second special button 120 corresponding to the destination floor button 119 are determined to be registered as a special destination floor registration that is registered by simultaneously pressing down (step ST5). Specifically, the control device 1 determines whether or not button-on signals of any of the destination floor buttons 119 and the second special button 120 are input simultaneously. If control device 1 determines that the button-on signals of any destination floor button 119 and second special button 120 are not input at the same time, it determines that it is not special destination floor registration (step ST5: No), and normal operation mode Is maintained (step ST20). That is, after the opening / closing door 103a is opened, the control device 1 maintains the normal operation mode unless the destination floor button 119 and the second special button 120 are pressed simultaneously within a predetermined time.

  When determining that the button-on signal of any destination floor button 119 and the second special button 120 is simultaneously input, the control device 1 determines that the special destination floor is registered (step ST5: Yes), and starts from the normal operation mode. The mode is switched to the display regulation operation mode (step ST6). That is, when the destination floor button 119 and the second special button 120 are simultaneously pressed within a predetermined time after the opening / closing door 103a is opened, the control device 1 switches from the normal operation mode to the display restriction operation mode. In the display restriction operation mode, the control device 1 makes no display on the display devices 111 of all the call registration devices 102 provided on each floor 110. That is, in step ST6, the control device 1 displays nothing on the display devices 111 of all the call registration devices 102 provided on each floor 110. Further, in the present invention, in the display restricted operation mode, the control device 1 causes the display devices 111 of all the call registration devices 102 provided on each floor 110 to display a car such as “execution of the display restricted operation mode”. Specific information unrelated to the current position 103 and the registered destination floor may be displayed.

  And the control apparatus 1 moves (lifts / lowers) the passenger car 103 to the floor 110 of the registered destination floor (step ST7). The control device 1 causes the passenger car 103 to land on the registered destination floor 110 and opens the door 103a (step ST8). It should be noted that the control device 1 holds the registered call registration between step ST6 and step ST8 even if the call registration is performed by the registration buttons 112 and 114 of the call registration device 102. That is, in the display restriction operation mode, the control device 1 does not respond to the call registration until the car 103 arrives on the floor 110 of the destination floor registered by the destination floor button 119 and opens and opens the door. In this way, in the display-restricted operation mode, the control device 1 has at least the registration button 112 of the call registration device 102 until the car 103 arrives on the floor 110 of the destination floor registered by the destination floor button 119. , 114 is suspended.

  Then, the passenger gets out of the car 103 on the registered destination floor. The control device 1 closes the open / close door 103a when a predetermined time elapses without the door open button 117 being operated and the button on signal of the door open button 117 not being input (step ST9). The control device 1 determines whether or not the call registration is performed by pressing the registration buttons 112 and 114 of the call registration device 102 (step ST10). Specifically, the control device 1 determines whether or not the button-on signal of the registration buttons 112 and 114 of the call registration device 102 is input. When determining that the button-on signal of the registration buttons 112 and 114 of the call registration device 102 is not input, the control device 1 determines that the call registration is not performed (step ST10: No), and sets the car 103 to, for example, the ground After moving to the reference floor such as the surface, landing, and opening the door (step ST15), the display restriction operation mode is switched to the normal operation mode (step ST30). As described above, when the call registration is not performed by the registration buttons 112 and 114 of the call registration device 102 during the display restriction operation mode, the control device 1 sets one predetermined reference among the plurality of floors 110. When the car 103 arrives on the floor and opens, the display restriction operation mode is switched to the normal operation mode.

  When the control device 1 determines that the button-on signal of the registration buttons 112 and 114 of the call registration device 102 is input, the control device 1 determines that the call registration is performed (step ST10: Yes), and the call registration is performed using the registration buttons 112 and 112. It is determined whether or not the special call registration is registered by pressing one of 114 and the first special button 113 simultaneously (step ST11). If control device 1 determines that it is not special call registration (step ST11: No), display control is performed after moving, landing, and opening doors (step ST16) to floor 110 where call car 103 is registered. The operation mode is switched to the normal operation mode (step ST30).

  When determining that the call is special call registration (step ST11: Yes), the control device 1 causes the car 103 to land on the floor 110 where the call registration has been made, and opens the door 103a (step ST12). Then, the control device 1 determines whether or not any destination floor button 119 is pressed within a predetermined time after the passenger enters the car 103 and the door 103a is opened, that is, the destination floor registration is performed. It is determined whether or not there is (step ST13). Specifically, the control device 1 determines whether or not a button-on signal of any destination floor button 119 is input within a predetermined time. If control device 1 determines that the button-on signal of any destination floor button 119 has not been input within a predetermined time, it determines that there is no destination floor registration (step ST13: No), and performs normal operation from the display restriction operation mode. The mode is switched (step ST30).

  If control device 1 determines that a button-on signal of any destination floor button 119 has been input within a predetermined time, it determines that there is destination floor registration (step ST13: Yes), and destination floor registration is either The destination floor button 119 and the second special button 120 corresponding to the destination floor button 119 are determined to be registered as a special destination floor registration that is registered by simultaneously pressing down (step ST14). If it determines with it not being special destination floor registration (step ST14: No), the control apparatus 1 will switch from display control operation mode to normal operation mode (step ST30). When the control device 1 determines that it is special destination floor registration (step ST14: Yes), the control device 1 returns to step ST7. As described above, when the call registration is performed (not the special call registration) by the registration buttons 112 and 114 of the call registration device 102 during the display restriction operation mode, the control device 1 performs the floor registration 110 on which the call registration is performed. When the car 103 is landed and opened, the display restriction operation mode is switched to the normal operation mode.

  As described above, the control device 1 determines the destination after the procedure in which the registration buttons 112 and 114 and the first special button 113 are operated at the same time and the car 103 that has landed on the call registered floor 110 is opened. An elevator operation mode switching method including a procedure in which the floor button 119 and the second special button 120 are simultaneously operated and a procedure for switching from the normal operation mode to the display restriction operation mode is executed.

  According to the control device 1 according to the embodiment, after the registration buttons 112 and 114 and the first special button 113 are pressed at the same time, and the car 103 that has landed on the floor 110 that has been registered by calling is opened, A specific operation is performed in which the destination floor button 119 and the second special button 120 are pressed simultaneously. Then, the control device 1 switches to the display restriction operation mode, does not display the destination floor on the display device 111, and does not respond to the call registration. Therefore, the control device 1 can easily switch the passenger's destination floor in the car 103 to the display restricted operation mode that the third party does not want to be known by a specific operation described above without using a dedicated key or the like. Can be made possible. Therefore, the control apparatus 1 can suppress that the passenger's destination floor in the passenger car 103 is known to a third party on each floor 110 in the display restriction operation mode. Furthermore, since the control device 1 does not respond to call registration in the display restriction operation mode, it is possible to prevent a third person from getting on the car 103. Furthermore, when the registration buttons 112 and 114 and the first special button 113 are pressed simultaneously, and the destination floor button 119 and the second special button 120 are pressed simultaneously, the control device 1 switches to the display restriction operation mode. Accordingly, when the registration buttons 112 and 114 and the first special button 113 are pressed simultaneously and then the third person gets on the car 103, the second special button 120 is not pressed and operated. It is possible to prevent the destination floor from being known.

  In the normal operation mode, the control device 1 can accommodate a large number of passengers in the car 103 and move the passengers to a desired floor. Control device 1 can control that a passenger's destination floor is known to a third party in the display restriction operation mode. Therefore, the control apparatus 1 can protect a passenger's privacy, suppressing the fall of driving efficiency. Furthermore, when the next call registration is not performed by the registration buttons 112 and 114 of the call registration device 102 during the display restriction operation mode, the control device 1 has landed and opened the car 103 on the reference floor. Later, the display regulation operation mode is switched to the normal operation mode. Therefore, the control apparatus 1 can suppress reliably that the destination floor of the passenger in the passenger car 103 is known to a third party on each floor 110 in the display restriction operation mode.

[Modification]
An elevator control device according to a modification of the embodiment of the present invention will be described with reference to the drawings. FIG. 5 is an explanatory diagram schematically illustrating an overall configuration of an elevator provided with an elevator control device according to a modification of the embodiment. In FIG. 5, the same parts as those of the embodiment are denoted by the same reference numerals and description thereof is omitted.

  In the modification, the control device 1 controls the operation of the plurality of elevators 101 installed in the building. The control device 1 executes group management control of the plurality of elevators 101 in addition to the control described in the embodiment. Specifically, the group management control means that, when a call is registered from any one of the call registration devices 102 of the plurality of elevators 101, an optimal elevator car 103 that responds to the call registration is assigned. . The control device 1 efficiently allocates the operation of the cars 103 of the plurality of elevators 101 and performs an efficient operation service as a whole of the plurality of elevators 101.

  Further, in the modification, when the control device 1 switches from the normal operation mode to the display restriction operation mode, only one or more predetermined elevators 101 among the plurality of elevators 101 are operated in the display restriction operation mode, and the remaining elevators 101 are operated. Is operated in the normal operation mode. That is, in the modified example, one or more predetermined elevators 101 can switch between the normal operation mode and the display restriction operation mode. Therefore, in the modified example, the second special button 120 is provided in the destination floor registration device 105 of one or more elevators 101 operated in the predetermined display restriction operation mode. In the modified example, the second special button 120 is not provided in the destination floor registration device 105 of the elevator 101 that is operated only in the normal operation mode.

  When the registration buttons 112 and 114 and the first special button 113 are pressed at the same time, the control device 1 of the modified example registers the call 103 of one or more predetermined elevators 101 by the registration buttons 112 and 114. To respond. Then, the control apparatus 1 causes one or more predetermined elevator cars 103 of the elevators 101 to be landed on the registered floor 110 by calling the registration buttons 112 and 114. At this time, if only one elevator 101 is operated in the display restricted operation mode, the elevator car 103 operated in the display restricted operation mode is called and registered by the registration buttons 112 and 114. It is made to land on the floor 110. When there are a plurality of elevators 101 operated in the display restricted operation mode, any of the elevator cars 103 operated in the display restricted operation mode is called and registered by the registration buttons 112 and 114. Land on floor 110.

  Then, the control device 1 of the modified example includes a destination floor button included in the destination floor registration device 105 in the car 103 after the opening / closing door 103a of the car 103 that has responded to the call registration by the registration buttons 112 and 114 is opened. When the button 119 and the second special button 120 are pressed simultaneously, the display restriction operation mode is switched. When the control device 1 of the modified example is switched to the display-restricted operation mode, the elevator 101 in which the destination floor button 119 and the second special button 120 in the car 103 are pressed simultaneously is separated from the group management control, and is executed. It is made to drive by display regulation operation mode like a form. Further, the control device 1 according to the modification executes group management control of the remaining elevators 101. In the modification, the control device 1 executes group management control of all the elevators 101 in the normal operation mode.

  According to the control device 1 of the modified example, in addition to the effects of the above-described embodiment, only one or more predetermined elevators 101 can be operated in the display restriction operation mode. It is not necessary to provide all the elevators 101 in the car 103. Therefore, an increase in cost can be suppressed. Moreover, since it is possible to drive only the predetermined elevator 101 in the display restriction operation mode, it is possible to drive a plurality of elevators 101 in a state close to the predicted driving efficiency.

  In the embodiment and the modification described above, the call registration device 102 is provided with the first special button 113, and the destination floor registration device 105 is provided with the second special button 120. When the registration buttons 112 and 114 of the call registration device 102 and the first special button 113 are operated at the same time, and the destination floor button 119 and the second special button 120 of the destination floor registration device 105 are operated at the same time, display restriction operation is performed. Switch to mode. However, the first special button 113 is not provided in the call registration device 102, and the second special button 120 is not provided in the destination floor registration device 105. In this case, the registration buttons 112 and 114 of the call registration device 102 are pressed down a predetermined number of times, pressed down for a long time, the destination floor button 119 of the destination floor registration device 105 is pressed down a predetermined number of times, or pressed for a long time. Alternatively, the mode may be switched to the display regulation operation mode.
