However, in the conventional system, it is not possible to perform the operation at an appropriate timing when the start condition is satisfied according to the demand. For example, if there is a start judgment based on the load conditions, in the registration by the destination floor registration device, the number is specified for each destination floor. It is possible to grasp it at the time when it is done. However, after the passenger has boarded the car and the load condition has been satisfied, the start determination timing is delayed. On the other hand, in the case of the up/down hall call registration device, the demand for calls in the up/down direction cannot be grasped at the time of call registration. . Therefore, in the current call registration method switching, it is possible to apply only one of the presence or absence of the start determination depending on the load condition, and there is a problem that the optimum start determination method cannot be selected for each call registration method.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a group supervisory control apparatus capable of selecting an optimum start determination method for each call registration method.

In the embodiment for achieving the above object, the start condition of the traffic pattern with high demand from a specific floor is set according to the call registration method selected from the destination floor registration device or the up-and-down call registration device at a specific time period. There are two conditions: a time condition only for switching the traffic pattern, and a load condition for switching the traffic pattern when the load of the car departing from the specific floor in the specific time zone exceeds a certain number. Determine whether to switch when When the landing destination floor registration device is selected as the call registration method, if the start condition of the traffic pattern with high demand from a specific floor is not only the time condition for switching the traffic pattern in a specific time period, a specific If the load condition is met during the time period, the start condition is set to switch the traffic pattern.

<First embodiment>
<<Configuration of Embodiment>>
FIG. 1 is a block diagram showing the configuration of the elevator system of the embodiment. FIG. 2 is a block diagram showing the configuration of the group supervisory control device of the embodiment. The block diagrams shown in FIGS. 1 and 2 are commonly used in the following first to seventh embodiments.

As shown in FIG. 1, the elevator system 1 includes a group supervisory control device 10, and under the control of the group supervisory control device 10, an A-car control device 30A that controls the A-car, and a B-car control device that controls the B-car. It comprises a device 30B and a C-car control device 30C that controls the C-car. The A car controller 30A controls the car 40A, the B car controller 30B controls the car 40B, and the C car controller 30C controls the car 40C. Load sensors 41A, 41B, and 41C for detecting respective car loads are installed on the respective cars 40A, 40B, and 40C.

In addition, destination floor registration devices 51 and 52 and up/down call registration devices 61 and 62 are installed in the hall of each floor.

As shown in FIG. 2, the group supervisory control device 10 includes a destination floor registration information input unit 11, an assigned car information output unit 12, an up/down call registration information input unit 13, an up/down call button lighting information output unit 14, A hall call registration method determination unit 15 is provided. The group supervisory control device 10 also includes an allocation control unit 16, a call registration-specific traffic pattern start condition determination unit 17, a timer unit 18, a load signal input unit 19, an allocation switching unit 20, and an allocation command output unit 21. and

The destination floor registration information input unit 11 inputs the destination floor registration information from the hall destination floor registration devices 51 and 52 .

The assigned elevator car information output unit 12 outputs the assigned elevator car information to the corresponding hall destination floor registration devices 51 and 52 .

The up-down call registration information input unit 13 inputs up-down call information from the up-down call registration devices 61 and 62 .

The up/down call button lighting information output unit 14 outputs lighting information indicating that the car is the assigned car to the corresponding up/down call registration devices 61 and 62 .

The hall call registration method determination unit 15 determines whether to use the hall destination floor registration devices 51 and 52 or to use the up/down call registration devices 61 and 62 as the hall call registration method.

The assignment control unit 16 performs elevator car assignment control based on the destination floor information input from the hall destination floor registration devices 51 and 52 or the top and bottom call information input from the top and bottom call registration devices 61 and 62 .

The call registration-specific traffic pattern start condition determination unit 17 determines each start condition of a plurality of preset traffic patterns. Here, the "traffic pattern" refers to driving at the time of arrival at work, driving at the end of work, or driving at lunch time for each special floor such as the standard floor (entrance floor), cafeteria floor, event venue floor, etc., depending on the time period. , driving at the start of an event, driving at the end of an event, etc. There are two types of "starting conditions": a time condition for switching traffic patterns based only on time, and a "time + load" condition that considers elevator demand in addition to time. The call registration-specific traffic pattern start condition determination unit 17 determines the start condition based on the time condition for switching the traffic pattern only by the time period and the "time + load" condition for switching when both the time period and the load condition are satisfied. The load conditions are determined based on load signals from the load sensors 41A, 41B, and 41C. However, the demand (the number of users of the elevator car) may be obtained based on camera images instead of the load sensor. Also, in this specification, load conditions and demand conditions are treated as synonyms.

The timer unit 18 operates at a preset time and outputs time data to the call registration-specific traffic pattern start condition determination unit 17 .

The load signal input unit 19 inputs load signals from the load sensors 41A, 41B, and 41C that measure the load of each car, and supplies them to the call registration-specific traffic pattern start condition determination unit 17 .

The assignment switching unit 20 generates an assignment command for switching the currently assigned car to the assigned car newly assigned by the assignment control unit 16 .

The assignment command output unit 21 outputs an assignment command to the assigned car controller.
