A landing destination floor registration device 50 is installed on a standard floor (for example, the first floor), and up/down call buttons 60 and 70 are installed on the landings of other floors.

The group supervisory control device 10a includes a peak demand determination unit 11a, a reference floor pullback door closing standby command output unit 12a, a destination call demand calculation unit 13a, a destination call allocation control unit 14a, and an upper and lower call allocation control unit 15a. , and an allocation command output unit 16a. An allocation control unit 20a is composed of the destination call allocation control unit 14a and the up/down call allocation control unit 15a.

Each elevator car control device 30A, 30B, 30C has the same functional configuration, and includes an assignment response control unit 31, a reference floor pullback door closing standby control unit 32, an elevator information output unit 33, and a car call registration. 34 and an up-down call registration unit 35 .

The peak demand judgment unit 11a of the group supervisory control device 10a judges from the day of the week, the time of day, the load in the car, etc. that it is the peak hour such as the working hours.

The reference floor pull-back door close standby command output unit 12a closes the pull-back door of the free car to the reference floor when the peak demand judgment unit 11a judges that it is a peak time and each car is in a free state with no call to respond. A retraction door closing standby command for waiting is output to the free basket.

The destination call demand calculation unit 13a calculates the demand for departures from the reference floor, which is the installation floor of the hall destination floor registration device 50, and the traffic demand to each floor, based on the destination call registration information from the hall destination floor registration device 50.

The vertical call registration unit 35 registers the vertical call information from the vertical call buttons 60 and 70 .

Next, the operation of the first embodiment will be described based on the flowchart of FIG.

The peak demand judgment unit 11a judges the peak demand of each car (step S1). Judgment as to whether or not there is a peak demand is based on a preset time period, such as the morning arrival time period, lunch time period, and leaving time period. Alternatively, it can be determined by grasping the state of congestion from the load of each car output from the elevator information output unit 33 .

If it is determined that it is the peak time period (step S1 YES), the machine loop of steps S2 to S7 is started. In this car loop, first, it is determined whether or not the car is free. That is, it is determined whether or not there is a call to be answered (step S3).

If it is determined that the car is free (step S3 YES), the reference floor retraction door close standby command output unit 12a instructs the elevator car controllers 30A to 30C that control the car to move the car to the reference floor. (step S4).

Then, when the car arrives at the reference floor, the pulled-back car is put on standby with the door closed on the reference floor (steps S5 and S6).

Next, a description will be given using a specific example shown in FIG.

As can be understood from FIG. 3, the A car is in the free state on the 7th floor and is pulled back to the 1st floor, which is the standard floor, and waits for the doors to be closed. Similarly, car D is in a free state on the 6th floor, and shows a state of being pulled back to the 1st floor, which is the standard floor. Unit B is pulled back to the standard floor and waits for doors to be closed. Car No. C is running from the 2nd floor to the 3rd floor, car calls to the 7th and 8th floors are registered, and a destination floor in the receiving direction is registered at the 4th floor. In addition, E-car is waiting at the standard floor, but is waiting with the door open because the destination floor registration device 50 has assigned a destination floor call to the 6th floor.

As described above, in the first embodiment, in the DCS system in which the landing destination floor registration device 50 is installed on the reference floor, the car is pulled back to the reference floor during peak times such as the working hours, but instead of waiting with the door open. I'm trying to keep the door closed. As a result, it is possible to prevent the user from getting on by mistake. After that, when the destination call is registered by the hall destination floor registration device 50 on the reference floor and the number is assigned, the assigned number is put on standby with the door open. As a result, it is possible to improve service to users during peak demand.

In particular, the group supervisory control device 10b of the second embodiment is characterized by including a door-close waiting car weight value setting unit 17b. Other configurations are the same as those of the first embodiment.

During peak hour operation, if there is a car waiting with the door open and assigned a destination call on the standard floor, the door-open standby car weight value setting unit 17b determines whether the car on the standard floor waiting with the door open is on a floor other than the standard floor. In order to make it easier to allocate hall calls (destination calls or vertical calls) generated on floors, it is difficult to allocate hall calls generated on floors other than the standard floor to cars that have been pulled back to the standard floor and are waiting for the doors to be closed. weight value information for the destination call assignment control unit 14b and the up-down call assignment control unit 15b.

Next, the operation of the second embodiment will be described based on the flowchart of FIG.

If it is determined that it is the peak time zone (step S11 YES), it is determined whether or not a hall call has occurred at a floor other than the standard floor (step S12). If a hall call is generated at a floor other than the standard floor (step S12 YES), a car loop of steps S13 to S16 is started.

If a destination call is registered on the standard floor and there is a car waiting with the doors open, the hall call (destination call or up/down call) for a floor other than the standard floor is assigned to another car on the other standard floor with the door closed. If the passenger moves to the next floor, there is a concern that the responsiveness to the next destination call to the reference floor will be deteriorated. For this reason, a weight value is set and added to the car waiting for door closing on the reference floor (step S14 YES) for hall calls on floors other than the reference floor (step S15). Then, the optimum car number is assigned with the weight value added (step S17). This suppresses the assignment of hall calls to other floors, and makes it easier to allocate the hall calls of floors other than the reference floor to the cars that are waiting with the doors open and that are assigned destination calls of the standard floor.

As described above, in the second embodiment, it is possible to preserve the closed waiting car on the standard floor, and to improve the service to users during peak demand.

An allocation control unit 20c is composed of the destination call allocation control unit 14c and the up/down call allocation control unit 15c. In particular, the group supervisory control device 10c of the third embodiment is characterized by comprising a car passenger number detection unit 18c and a car inner door close button enable/disable output unit 19c. Other configurations are the same as those of the first embodiment.

The number-of-occupants-in-car detector 18c detects the number of people in the elevator car from the load.

The car inner door close button enable/disable output unit 19c disables the door close button in the car to which the destination call for the standard floor is assigned and which is waiting for the door to open on the standard floor during peak hour operation. and the number of passengers in the car waiting with the doors open on the standard floor after the destination call for the standard floor calculated by the number-of-occupants-in-car detection unit is assigned is registered with the destination call for the standard floor. When the number of passengers is greater than or equal to the number of passengers, or when a predetermined time or more elapses after the last destination call for the reference floor is registered, the door closing button in the waiting car with the door open, which has been disabled, is enabled.

Next, the operation of the third embodiment will be described based on the flowchart of FIG.

If it is determined that it is the peak time zone (step S21 YES), it is determined whether or not a destination call has been registered at the reference floor (step S22). If the destination call for the standard floor is assigned and there is a car waiting with the doors open on the standard floor, the car inner door close button is disabled (step S23). Next, it is determined whether or not the number of passengers registered with the destination call has boarded the assigned car (step S24). If the number of passengers has boarded (step S24 YES), or if a certain time has passed since the destination was last registered on the standard floor (step S25 YES), the car inner door close button of the allocated car is activated. (Step S26).

As described above, the third embodiment has a function of enabling/disabling the car inner door close button of a car which is assigned a destination call of the reference floor and is waiting with the door open on the reference floor. If the number of passengers in the car exceeds the number of passengers registered in the destination call, or for a certain period of time after the last destination call was registered at the standard floor The user is prevented from failing to board by validating it when the above elapses. Also, the departure interval from the standard floor can be optimized. As a result, it is possible to improve service to users during peak demand.
