According to FIGS. 2 and 6, allocation and guidance system A
I will explain (normal).

Rule 1 is that when two double-deck elevators are on the 17th and 18th floors, a down hall call occurs on the 12th floor. At this point, the halls on the odd and even floors or the even and odd floors have not been called consecutively, so the double deck elevator of Unit B is assigned by MIN-MAX control and the reservation information is suspended.

[0012] According to Rule 2, if further downward hall calls are generated on the 11th floor, hall calls for consecutive floors in the same direction can be made, so that they are assigned to the same double-deck elevator B at once. Immediate reservation information.

Rule 3 is from the state of Rule 1 to Unit 1
This is when a car call on the first floor occurs. At this time, 12
When the hall call in the descending direction occurs on the floor, it means that the consecutive hall calls occur. Therefore, the hall calls in the descending direction on the 12th floor assigned to Unit B are reassigned and collectively assigned to Unit A. Allocation and immediate reservation information.
As rule 4, if a hall call occurs for 30 seconds, the double deck elevator will be guided and controlled.

In the present invention, the display guidance mode is selected and displayed and guided based on the result of the traffic demand learning table of SF23, and control such as blocking an inconvenient call is performed depending on the traffic demand.

Here, the feature of the present invention is that the reservation guidance is temporarily held according to the traffic volume and the like, and the reservation is positively changed so that consecutive hall calls on the odd and even floors or the even and odd floors can be used for the same double deck. It is characterized by controlling a double-deck elevator that is assigned to all elevators at once.

It is assumed that the programs SF10 and SF20 are divided into a plurality of tasks and are managed under a system program that performs efficient control, that is, an operating system (OS).

Therefore, it is possible to freely start the program from the system timer or from another program.

FIG. 5 is an overall processing flowchart of the operation control program.

The operation control program E5 is started after the power is turned on or by restarting. First, in the initial process E10, an initial process such as a clear process for the control data table SF11 and the like is executed.

Next, steps E20 to E70 are repeatedly executed until the power is turned off or a program abnormality occurs, and the group management control is executed. In step E20, the hall call for all floors is input, and the hall call table SF12 is entered.
Perform the registration process to set to. At step E30, the communication data from the machine controller is stored in the double deck elevator control data table SF11.

At step E35, the current mode of AC demand is identified, and accordingly, the guide display rule, the operation management method, and the hall call allocation rule are selected.

In step E37, the hall call table S
F12 and double deck elevator specification table SF1
3 and the operation parameter table SF14 which is set or automatically learned and adjusted for each traffic demand mode or time zone, and the double-deck elevator control data table SF11 is created according to the driving traffic demand mode identified above.

At step E40, service guide processing is performed according to the assignment of hall calls and the guide rule according to the situation, the learned result, the current traffic demand, and the guide situation.

In step E60, the process is executed every 10 seconds by the timer.

Further, a request for re-evaluating the service double-deck elevator for the assigned hall call in which the passengers on board the priority floor and the like are detected and the predicted degree of congestion in the car upon arrival exceeds the congestion degree allowable value WGC (k) in the car Step E60
And continuously control the congestion degree. It also requests reassignment when an abnormally long wait occurs due to frequent car calls or piles of luggage.

Then, at step E70, the distributed operation of the double-deck elevator and the other operation management control such as the adjustment of the departure interval on the lobby floor are performed.

FIG. 8 is a table for assignment and guidance control. FIG. 8A is a call assignment rule selection table, and FIG. 8B is an explanatory diagram showing combinations of hall call assignment rules and guidance rules.

FIG. 7 is a flow chart of processing showing an embodiment of the hall call allocation control described in step E40 of FIG. In steps F10, F100, and F110, hall call allocation processing for all floors of ascending and descending is sequentially performed. In step F50, it is determined whether or not there is a need for guidance or allocation in the loop. This judgment may judge whether there is a newly generated hall call,
Whether or not a call is registered may be simply determined, and the determination method is determined by a guide rule, a call assignment rule, a review due to long wait or congestion, and an additional assignment method. If the allocation is necessary, the process proceeds to step F60, and if the guidance rule selection is determined, the process of step F80 is performed.
If not decided, the guidance method selection process of step F70 is performed as shown in FIG.
The guide rule is determined by the hall call allocation rule T100.

In step F80, an elevator is selected from the evaluation values of the waiting time, the congestion degree, and the evaluation value giving priority to a specific floor, and the call is assigned.

After the guide rule is decided, the guide rule is selected such that it is assigned to a machine without a signal for blocking the registration of a new hall call, or is not assigned to a machine that is likely to be overloaded. The setting is performed from the setting of the parameter table T200 set for each. (1) The estimated arrival time after hall call registration is 30
If it is within [seconds], immediate reservation guidance is executed, and if it is 30 [seconds] or more, guidance is suspended. (2) Reservation information is not provided for both. (3) Guidance will be provided in the direction of first service.
