It is a flowchart which shows the flow of the process of the operation control by an elevator control apparatus. It is a flowchart which shows the flow of the process of the operation control by an elevator control apparatus when the hall call of the destination floor is registered.

  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 shows an overall configuration of an elevator system according to an embodiment of the present invention. In the present embodiment, three elevators are installed in a building on the 10th floor, and a machine room in which a control device and a hoisting machine (not shown) are installed is located above the 10th floor of the building.

  The elevator control device 1 installed in the machine room includes a group management control device 2 and three unit control devices 3. Depending on the hall call that sets the boarding floor of the user or the car call that sets the destination floor of the user, the group management control device 2 can balance the three elevators in consideration of the waiting time or the like. Control dispatch and driving so that passengers are transported efficiently. At this time, the group management control device 2 operates each elevator based on information on the position and traveling direction of the car 4, the status of the car call, the degree of congestion in the car 4, etc. transmitted from each car control device 3. The situation was judged, and the hall call generated by the elevator user operating the hall call button 9 on each floor was assigned to one of the three elevators based on this operation situation, and the hall call was assigned. An allocation signal and a reservation lamp signal are transmitted to the elevator machine control device 3.

  The number control device 3 executes traveling control and door opening / closing control of the elevator number. In addition, the machine control device 3 is installed in a hall (hall) by an assignment signal or a reservation lamp signal from the group management control device 2, and display control of the display 7 for displaying a car position or the like, or lighting control of the hall lantern 10 Is executed to guide the arrival of the car, the position of the car, etc. to the user at the hall, that is, the waiting customer.

  In the car 4, a destination floor button for a passenger to designate a destination floor 5, an operation switch 6 for switching from a normal operation mode to a special operation mode described later, a display 7 for displaying a car position, etc. An in-car guide device provided with the guide device 8 is provided. The signal of the destination floor button 5 and the signal of the operation changeover switch 6 are input to the machine control device 3, and the control signals of the display 7 and the voice guidance device 8 are transmitted from the machine control device 3.

  Hall call buttons 9, hall lanterns 10, and displays 7 are installed at halls on each floor. The user can call the car 4 on each floor by pressing the hall call button 9. In addition, the machine control device 3 lights the hall lantern 10 and displays the car position on the display 7. As a result, the waiting passenger is notified of the arrival and traveling direction of the car 4, and the current position of the car 4.

  The assignment changing unit 2-2 in the group management control device 2 is configured to receive a signal from the hall call button 9, a hall call that has already been assigned, and the position and traveling direction of the car 4 transmitted from the machine control device 3. The elevator number to which the newly generated hall call is assigned is selected from the information regarding the call status and the degree of congestion in the car 4, and an assignment signal indicating the selected elevator number is transmitted to the assignment unit 2-1. The allocation unit 2-1 transmits the allocation signal received from the allocation change unit 2-2 to the number control device 3 that controls the selected elevator number indicated by the allocation signal.

  Signals communicated between the hall call button 9 and the group management control device 2 are directly input / output in the group management control device 2 in FIG. 1, but are input to the group management control device 2 via the machine control device 3. It may be output.

  In the present embodiment, the assignment changing unit 2-2 in the group management control device 2 uses the hall call button 9 on each floor for the elevator car whose operation mode is switched to the special operation mode by the operation changeover switch 6 in the car. Do not assign hall calls. Furthermore, the elevator control device 1 assigns the allocation change unit 2 in the group management control device 2 when there is a hall call on the same floor as the destination floor (destination floor) indicated by the car call registered by the in-car destination floor button 5. -2 assigns the hall call to other elevators and prevents the elevators that have been switched to the special operation mode from arriving at the destination floor until the passenger enters the car of the other assigned elevators. Control the operation of each elevator.

  Next, operation control executed by the elevator control device 1 of the present embodiment will be described with reference to FIGS.

  FIG. 2 is a flowchart showing a flow of operation control processing executed by the elevator control device 1 of the present embodiment. Here, the waiting passengers enter the car 4 of the elevator A that has arrived at the hall, and the operation changeover switch 6 in the car 4 is switched to ON to change the operation mode of the elevator to the special operation mode. Shall.

  The group management control device 2 determines whether or not the operation changeover switch 6 is ON based on the presence or absence of the changeover signal of the operation changeover switch 6 received via the unit control device 3 of the No. A unit (step S1). Is determined (Y in step S1), the ON signal detection information is transmitted to the assignment changing unit 2-2. When it is not determined to be ON (N in Step S1), the elevator control device 1 controls the operation of the No. A machine in the normal operation mode.

  When receiving the ON signal detection information, the allocation changing unit 2-2 changes the allocation of the hall call that has already been allocated to the A-unit to another elevator unit (B-unit or C-unit) (step S2). As a result, it is possible to prevent the car of No. A from stopping on the way to the passenger's destination floor. Therefore, the passenger of the No. A aircraft can go to the destination floor without getting on with other passengers.

  After step S2 is executed, the group management control device 2 registers the destination floor call (car call) depending on the presence or absence of the destination floor call (car call) signal from the destination floor button 5 of the car 4 of the car A. If it is determined whether or not the destination floor call has been registered (Y in step S3), the hall display 7 of Unit A on the floor other than the destination floor (target floor) indicated by the destination floor call 7 Is turned off and a turn-off command signal is transmitted to the machine control device 3 of the machine A. If it is not determined that the destination floor call has been registered (N in step S3), step S1 is executed again.

  Upon receipt of the turn-off command signal, the machine control device 3 of the car A turns off the hall display 7 of the car A on the floor other than the destination floor (the destination floor) (step S4). It is notified to the user who is in the hall of floors other than the target floor that the vehicle is not operated in the normal operation mode. Here, the display 7 on the destination floor is not turned off and is in the same display state as the normal operation mode. As a result, it is possible to prevent others at the landing on or near the destination floor from knowing that Unit A is in the special operation mode and deliberately ambushing.

  After step S4 is executed, in response to the operation command from the group management control device 2, the car controller 3 of the car A does not respond to the hall call on the way floor to the destination floor, and the car 4 Operation control of the No. A machine is performed so as to go to the destination floor (step S5).

  After step S5 is executed, the group management control device 2 determines whether or not a hall call by the hall call button 9 on the destination floor is registered (step S6). When the hall call of the destination floor is registered (Y in step S6), as will be described later with reference to FIG. 3, the passenger waiting at the destination hall is a car 4 of another machine (hereinafter referred to as No. B). Until the vehicle enters the car, the operation of the car A is controlled so that the car 4 of the car A does not reach the destination floor.

  FIG. 3 is a flowchart showing a flow of operation control processing executed by the elevator control device 1 when the hall call of the destination floor is registered. The operation control process shown in FIG. 3 corresponds to the process between A and B in FIG.

  First, the group management control device 2 determines whether or not the waiting customer at the landing on the destination floor has entered the car 4 of the car B (step S7). For example, the elevator car 4 of the B machine arrives at the destination floor, the hall call of the destination floor assigned to the B machine is deleted, and the destination floor call (car) is pressed by the destination floor call button 5 in the elevator car 4 of the B machine. When the call is registered, it is determined that the waiting customer has entered the B-unit.

  When it is determined that the waiting passenger on the destination floor has not entered the car 4 of the B-unit (N in step S7), the group management control device 2 determines that the car 4 of the A-unit has reached the previous floor of the destination floor. It is determined whether or not (step S8).

  When it is determined that the car 4 of Unit A has reached the previous floor (Y in step S8), the group management control device 2 stops the car of Unit A on the previous floor of the destination floor and opens the door. A command is given to the machine control device 3 of the A machine so as to wait in the closed state (step S9). After executing step S9, the group management control device 2 further gives guidance indicating that there is a waiting customer at the landing on the destination floor on the display 7 or the voice guidance device 8 in the car No. A. Is commanded to the machine control device 3 of the No. A machine (step S10). Here, when the car 4 of the Unit A is stopped at the destination floor and is made to stand by, the car position is displayed on the display 7 of the landing floor on the destination floor, so that the waiting customer on the destination floor has arrived at the destination floor. However, there is a possibility of being suspicious or frustrated that the door cannot be opened. On the other hand, the suspiciousness and dissatisfaction of such waiting customers can be suppressed by stopping the car 4 of the A-unit at the floor immediately before the destination floor and waiting.

  When it is determined in step 8 that the car 4 of Unit A has not reached the previous floor (N in Step S8), the group management control device 2 moves the car 4 of Unit A to the hall on the destination floor in Step S6. A command is given to the machine control device 3 of the No. A machine so as to drive at a lower speed than when it is determined that the call is not registered and to go to the destination floor (step 11).

  In this embodiment, passengers of Unit A are waiting for passengers at the landing on the destination floor when the car is traveling toward the destination floor or when the car is waiting on the previous floor. If it is intended to arrive at the destination floor before boarding, press and hold the door open button provided on the operation panel in Unit A (step S12) or switch the operation switch 6 to OFF (step Through S13), the low-speed driving state or the standby state is canceled, and the car 4 of the A-unit can arrive at the destination floor, open the door, and get off.

  Specifically, after step S10 or step 11 is executed, the group management control device 2 determines whether or not the door open button has been pressed for a predetermined time or more (step 12). When it is determined that the door open button has been continuously pressed (Y in Step 12), the group management control device 2 cancels the standby state or the low-speed operation state of the car A of the car A and moves the car 4 of the car A The machine control device 3 is commanded to travel toward the destination floor (step S14). If it is not determined that the door open button has been continuously pressed (N in Step 12), then the group management control device 2 determines whether or not the operation changeover switch 6 in the car 4 of Unit A is ON. Is determined (step S13). When it is determined that the operation changeover switch 6 is ON (step S13), the processes after step S7 are executed again. If it is not determined that the operation changeover switch 6 is ON (N in Step S13), that is, if it is determined that the operation changeover switch 6 is turned OFF, the group management control device 2 uses the car 4 of the No. A car. The vehicle controller 4 is instructed to cancel the standby state or the low-speed operation state of the vehicle and cause the car 4 of the car A to travel toward the destination floor (step S14).

  According to the operation control shown in FIG. 3, Unit A waits on the previous floor until the passenger waiting on the destination floor gets into Unit B, so that the passenger of Unit A waits for the passenger on the destination floor when it arrives at the destination floor. And you do n’t have to face each other. Furthermore, the passenger of No. A can release the special operation mode set at the time of departure by long-pressing the door opening button or switching the operation changeover switch to OFF. In the operation control flow of FIG. 3, step S12 and step 13 may be omitted. Even in this case, the passengers of the Unit A do not have to meet the waiting customers on the destination floor when they arrive at the destination floor through steps S7 to S11.

  After step 14 is executed or when it is determined in step S6 in FIG. 2 that the destination hall call is not registered (N in step S6), the process in step S15 in FIG. 2 is executed. That is, when the car 4 of the car A arrives at the destination floor, the group management control device 2 opens the door without performing the arrival guidance by the hall lantern 10 or the like so that the passenger can get off the car. 3 (step S15). This improves privacy protection by not letting others in the vicinity of the landing on the destination floor know the arrival of the car of the A-unit. After step S15 is executed, the group management control device 2 further returns the display 7 of the Unit A provided at the landing on the floor other than the destination floor to the lighting state and notifies that the Unit A is available. .

  As described above, the elevator control device according to the present embodiment does not allow the user to meet other users in the car and to meet the user waiting at the landing on the destination floor. Elevator operation control becomes possible. Thereby, an elevator user's privacy can be protected reliably. Moreover, the safety of the elevator user can be ensured.

  In addition, this invention is not limited to the Example mentioned above, Various modifications are included. For example, the above-described embodiments have been described in detail for easy understanding of the present invention, and are not necessarily limited to those having all the configurations described. Furthermore, it is possible to add, delete, and replace other configurations for a part of the configuration of the embodiment.

  For example, in the above-described embodiment, the elevator car of Unit A may wait on the destination floor without closing the door until the waiting passenger on the destination floor gets into the car of Unit B. In this case, the arrival guidance for Unit A by the display or hall lantern provided at the landing on the destination floor is not executed. Further, the display may display that the position of the car of Unit A is another floor such as the previous floor.
