It is.

In this embodiment, each landing is shown in FIG.
It is assumed that the landing operation devices 4A and 4B of either one of the types shown in FIG. 2B (or the types having the same function) are installed.

In this embodiment, when each car operates in response to a call, either the first operation mode shown in FIG. 3A or the second operation mode shown in FIG. 3B is performed. In the drawings, a represents an upper car, b represents a lower car, Δ represents a hall call, and O represents a car call. That is, the car in the first operation mode exclusively transports passengers from the even floor to the even floor or from the odd floor to the odd floor. The car in the second operation mode exclusively transports passengers from the odd floor to the even floor or from the even floor to the odd floor.

When the car operating with the first or second operation mode specified responds to the last car call of the car, the specification of the operation mode is released and the car is newly assigned to the call. Until the operation mode is specified, the operation mode is not specified.

Next, the operation after the occurrence of a new call will be described with reference to FIG. When a hall call is input by the hall controllers 4A and 4B in step S1, it is determined in step S2 whether the call is a call from an odd floor to an odd floor or from an even floor to an even floor, or other than that. . In the case of the former call, the process proceeds to step S3, and in the case of the latter call, the process proceeds to step S6.

In step S3, it is determined whether the number of cars in the first operation mode is equal to or larger than a reference value. The procedure for setting the reference value will be described later. If the number of cars is equal to or larger than the reference value, the process proceeds to step S4, and the cars already executing the first operation mode are set as allocation candidates for new calls. If the number of cars is less than the reference value, the process proceeds to step S5, where a car in which the first operation mode is already being executed or a car in which no operation mode is designated such as in a standby state is set as a candidate for assignment to a new call. Set.

Next, when the process proceeds from step S2 to step S6, it is determined whether the number of cars in the second operation mode is equal to or larger than the reference value. If the number of cars is above the reference value,
Proceeding to step S7, a car already executing the second operation mode is set as an allocation candidate for a new call. If the number of cars is less than the reference value, the process proceeds to step S8, where a car in which the second operation mode is already being executed or a car in which no operation mode is designated, such as in a standby state, is set as an allocation candidate for a new call. I do. Steps S1 to S8 are performed by the assignment candidate selecting means 1E.

When the allocation candidates for the new call are set by the above steps, steps S9 and S10 are executed for each allocation candidate car. First, in step S9, a predicted arrival time indicating how many seconds each car can arrive at each floor, a predicted car load indicating a predicted car load value of each car at each floor, and the like are calculated. This prediction calculation procedure is a well-known procedure in the group management control, and a detailed description thereof will be omitted.

Next, in step S10, step S9
Each evaluation value is calculated for the case where each car is assigned to a new call, based on the prediction calculation result by. As the evaluation value, a calculated value for an evaluation index used in normal group management control, such as a predicted waiting time evaluation, a predicted fullness probability evaluation, or a prediction miss probability evaluation, may be obtained. Step S9 is performed by the predictive calculation means 1F, and step S10 is performed by the evaluation calculation means 1G.

Next, in step S11, step S1
Based on the various evaluation values calculated at 0, the assigned car determining means 1H determines the assigned car for the new call. Various procedures are conceivable for the procedure for determining the assigned car. In general, a car having the best overall evaluation value is selected by using a comprehensive evaluation function based on the concept of multi-purpose control as shown in the following equation. It is. (Comprehensive evaluation value of car) = (Estimated waiting time evaluation value) + Wa ×
(Estimated value of predicted fullness probability) + Wb × (Evaluation value of predicted missed probability) where Wa, Wb: weight

The weights Wa and Wb are coefficients indicating the degree of importance of each evaluation index. These weights W
a and Wb are typically calculated by simulation, etc.
Check the effect and set it. Also, it may be set appropriately according to the preference of the building owner.

If the assigned car for the new call is determined by the operation up to step S11 and the assigned car is not specified in any of the operation modes, the operation control means 1J responds to the new call in step S12. Operation mode to be assigned to the assigned car. Then, in step S13, the operation control unit 1J instructs the assigned car to perform a new assignment, and instructs an operation. At the same time, the forecast control means 1K causes the hall lantern 3
A, 3B is turned on, and the landing operation device 4A, 4A,
The forecasting machine corresponding to the new call is displayed on the forecasting machine display 4b, 4d of 4B, and the car assigned to the waiting customer is forecasted.

In the first embodiment (particularly, the operation flowchart of FIG. 4), the landing operation devices 4A and 4B are connected to the landing operation devices 4A and 4B in FIG.
It is shown that the object of the present invention can sufficiently achieve the object of the present invention. Of course, it is clear that the object can be achieved by using the type shown in FIG.
Also, if the destination information can be input at the landing, as in the form of FIG. 2B, the prediction calculation in step S9 in FIG. 4 can be made more accurate. Since there is no relationship, detailed description is omitted.

Next, the procedure for setting the reference value of the number of cars for executing each operation mode will be described with reference to FIG. Note that the series of steps in FIG. 5 are executed periodically (for example, every five minutes). First, at step S21, the traffic data collecting means 1B collects traffic data. For example, the following data can be considered as the data to be collected.

Data on the number of passengers on each floor: (first-mode passengers (up), first-mode passengers (down), second-mode passengers (up), second-mode passengers (down)) (Number of people getting off first mode (up), number of people getting off first mode (down), number of people getting off second mode (up), number of people getting off second mode (down)

In the above, the first mode indicates the movement from the odd floor to the odd floor or the even floor to the even floor, and the second mode indicates the movement from the odd floor to the even floor or from the even floor to the odd floor. With the conventional device, it is possible to collect the data of the number of people getting on and off the vehicle for each floor, but it is difficult to perform the above-described classification. However, in this embodiment, the landing operating device 4 shown in FIG.
By installing A and 4B, it is possible to classify whether the ride is in the first mode or the second mode. In addition, the getting-off mode can be classified from the car driving mode at the time of getting off.

Next, in step S22, the traffic data analysis means 1C analyzes the data obtained in step S21, and in step S23, the driving mode reference setting means 1D
Sets the reference value of the number of cars to execute each operation mode based on the analysis result of step S22. As the simplest of this analysis procedure, it is conceivable to classify the traffic in the building into the items in Table 1.

[0038]

[Table 1]

From Table 1, it is possible to calculate the classification of the traffic pattern (up-peak time, down-peak time, normal time, off-peak time, etc.) and the traffic ratio between the first mode and the second mode.
From these data, the reference number is set as follows, for example. Here, N is the number of cars, and the first mode traffic ratio represents the ratio of the first mode to the total traffic volume. At the time of a strong peak: The number of the first operation modes = (N−1) × the first mode traffic ratio The number of the second operation modes = (N−1) × the second mode traffic ratio

Normal peak time: Number of first operation modes = (N−2) × first mode traffic ratio Number of second operation modes = (N−2) × second mode traffic ratio Normal time: Number of first operation modes = (N−3) × first mode traffic ratio The number of the second operation modes = (N−3) × the second mode traffic ratio When the vehicle is idle: The number of the first operation modes = (N−4) × the first mode traffic ratio second Number of driving modes = (N−4) × Second mode traffic ratio

In the above description, since a large number of passengers are generated during peak hours, each car is often in service, and the number of cars corresponding to each operation mode is set as close as possible to the mode-specific traffic ratio. Also, during normal times or during off-peak hours, the mode is not set so often, and an empty car can be designated for each call occurrence. Note that the above is merely an example, and the classification may be further refined depending on the number of offices in the bank.

The effect of this embodiment will now be described with reference to FIG.
This will be described with reference to FIG. In general, when a DD elevator is applied, an escalator is installed near the elevator landing on the departure floor (the first floor and the second floor in FIG. 6), and passengers traveling to odd-numbered floors are left from the first floor and those traveling to even-numbered floors. Passengers are ascending to the second floor by an escalator and guiding the passengers to board from the second floor. In the past, in order to improve transportation efficiency during peak times on ordinary floors, the car was driven so that the car stopped only on odd-numbered floors from odd-numbered floors and only on even-numbered floors from even-numbered floors. The passengers are guided by a container.

In general, during peak hours, for example, when commuting, traffic from the departure floor occupies a large number as in the case of #B in FIG. 6 (A). However, although the absolute number is small, #
Inter-floor traffic, such as Unit A, occurs. Therefore, conventionally, as seen in the #A car at the peak time, passengers who go from the 14th floor to the 17th floor once reach the stairs by 1 stairs.
It is necessary to move to the 5th floor, which is not convenient.

However, in the first embodiment, since such a passenger only needs to get on the car in the second operation mode, it is not necessary to use a stair or the like. In addition, the number of cars operating in each operation mode is set according to traffic, so that during peak times, the number of cars that execute the second operation mode can be reduced, and compared to the conventional one. However, the transportation efficiency does not decrease. In this way,
It is possible to improve the convenience while securing the transportation efficiency at the peak time.

In normal times, a lot of intermediate floor traffic occurs, but the most frequent one is access to the departure floor (get on / off). For example, as shown in FIG. 6B, especially when there is an express zone (3rd to 12th floors), if a call is answered regardless of the destination, many car calls can be made before reaching the departure floor. Return to the departure floor tends to be delayed. For example, if the #A car in FIG. 6B responds to the hall calls on the 20th and 18th floors,
Four stops on the 8th, 15th and 14th floors are required.

However, in the first embodiment, since the answering machine is separated according to the call and controlled so that passengers can share the car, the number of stops of each car is reduced, and the return to the departure floor is particularly quick. Become. In general, "diversion control" for each destination floor
, It is possible to increase the utilization rate of the car and improve the transport efficiency.

[0047]

As described above, according to the first aspect of the present invention, the lower car is in the first operation mode in which only the odd (even) floors are used, the upper car is used only in the even (odd) floors, and the odd cars are even-numbered. Implement the second operation mode in which only the calls from the floor or even-numbered floor to the odd-numbered floor are performed. When a call is input from the landing, one of the elevators is selected and assigned to the call, and this is assigned to the landing. Since the notification is made, the number of stops of each car can be reduced, the transport efficiency can be improved, and the convenience at the peak time can be increased.

In the second invention, when a call is input from the landing, one of the elevators in which the corresponding operation mode is being executed is selected and assigned to the call, and this is reported to the landing. According to the third aspect, when a call is input from the landing, one of the elevators in which the corresponding operation mode is being executed and the elevators in which none of the operation modes is being executed is selected and assigned to the call. When the elevator is not in operation in any of the operation modes, the elevator is designated as the corresponding operation mode and this is notified to the landing, so that the car in the operation mode corresponding to the call can be selected. In addition, since the useless assignment is not performed, the number of stops of each car can be reduced and the transportation efficiency can be improved.

Further, in the fourth invention, the landing hall is provided with a destination button indicating an odd-numbered ascending direction, an odd-numbered descending direction, an even-numbered ascending direction, and an even-numbered descending direction.
A destination floor button is provided, and a display is provided to notify the elevator assigned to the call by the destination button and the destination floor button, respectively, so that the waiting passengers at the landing can be switched according to the type of the destination floor and the destination floor without being lost. It can be made to.

According to the sixth aspect of the present invention, the traffic data of the elevators is analyzed, and the reference value of the number of elevators used in each operation mode is set based on the analysis result of the traffic data. An appropriate number of operation modes can be set, and transportation efficiency can be ensured.

According to the seventh aspect of the present invention, when a call is input from the landing, if the number of elevators performing the corresponding operation mode is equal to or larger than the reference value, the elevator is selected from the elevators performing the corresponding operation mode. If one of the elevators is selected and assigned to a call, and the number of elevators that are performing the corresponding operation mode is less than the reference value, the number of elevators that are performing that operation mode and the number of elevators that are not performing any operation mode In addition to selecting one from and assigning it to a call, if this assigned elevator is not in any of the operation modes, this elevator is designated as the corresponding operation mode and this is reported to the landing, In normal times, a car that can flexibly respond to various calls can be secured. In addition, transportation efficiency can be ensured.
