Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an elevator apparatus (a so-called double deck elevator) in which a plurality of cars are provided above and below a single shaft, and the plurality of cars are connected to each other, and a method of operating the same.
[0002]
[Prior art]
Conventionally, in order to improve the operation efficiency of a double deck elevator, there is a technique in which floors that can be stopped are divided into upper and lower cars in advance such that the lower car is an odd floor and the upper car is an even floor. There is also a technology that makes it possible to stop both upper and lower cars only on a specific floor.
[0003]
For example, in Japanese Patent Application Laid-Open No. 7-228435, destination buttons such as “to even numbered floor” and “to odd numbered floor” are provided at the hall, and if the user wants to go to the even floor, the “even numbered floor” hall button is pressed. As a result, if the upper car is to serve even floors, the upper car will arrive.
In Japanese Patent Laid-Open No. 7-133302, one of the upper and lower cars is basically stopped on the even floor and the other car is stopped on the odd floor. It can be stopped. In Japanese Patent Laid-Open No. 4-189271, if a car is left unloaded at a landing where there is a head car of the same car (the upper car if the direction of the car is upward, the lower car if it is downward), the next car is stopped. Yes.
[0004]
As for hall calls at consecutive floor halls, Japanese Patent Application Laid-Open No. 7-109076 assigns hall calls generated in the same direction on consecutive floors to the same machine.
[0005]
[Problems to be solved by the invention]
In the above technique, even-numbered floor stops and odd-numbered floor stops are distinguished regardless of the traffic flow in the building, or both the upper car and the lower car are stopped only for a preset floor. For this reason, it is not always possible to say that the operation urging the traffic of the building is being carried out. In addition, in the technique of stopping the same car when a hall call in the same direction is generated on two consecutive floors, this is the first time that two consecutive hall calls are generated.
[0006]
The present invention has been made to solve the above-described problems. For a landing call that is newly generated by allocating a car in advance to a landing call that may occur in the future as well as the present. The purpose is to reduce the waiting time.

DETAILED DESCRIPTION OF THE INVENTION
Embodiment 1 FIG.
FIG. 1 is a configuration diagram of an elevator apparatus according to this embodiment, and particularly describes a control portion of the elevator apparatus. Reference numeral 11 denotes hall call registration means for passengers to register hall calls. Specifically, an up button and a down button are installed on each floor, a destination button is installed on each floor, and a hall call is registered by recognizing that the passenger has pressed these buttons. Reference numeral 12 denotes an elevator assignment unit that determines an elevator car corresponding to the landing call registered by the landing call registration means, and reference numeral 13 denotes an assignment of the upper car or the lower car assigned by the car assignment unit 12. Upper car / lower car allocating means 14 is a congested floor determining means for determining a congested floor of each floor.
[0016]
Next, the control procedure of the elevator apparatus in the present invention will be described. FIG. 2 schematically illustrates the invention by way of example. FIG. 3 is a flowchart of control of the elevator apparatus in this embodiment. This shows a process from when a hall call is generated at a certain floor and the upper car or the lower car is stopped in response to this hall call.
Below, the control procedure of the elevator apparatus of this Embodiment is demonstrated using FIG. 2 and FIG.
[0017]
First, when a hall call is generated by pressing a hall call button at an elevator hall on a certain floor, the hall call is registered by the hall call registration means 11 (step S31). In FIG. 2, as shown at 23, an upward call is registered on the sixth floor.
The information on the hall call registered by the hall call registration means 11 is notified to the car number allocation means 12. In the case of an elevator system provided with a plurality of units, a unit that responds to the hall call is selected by the unit allocation means 12, and if only one elevator system is installed, that unit is caused to respond to the hall call. As a result, the number assigned to the hall call is determined (step S32).
[0018]
Next, the upper car / lower car assigning means 13 uses the floor assigned at step S32 where the hall call is registered, the floor directly above or below the floor (hereinafter referred to as the directly above / downstairs). Whether it has a destination call in the car. If the number assigned in step S32 does not have a destination call in the car on the floor where the hall call is generated or directly above / below it, the process proceeds to step S34, and if it does, the process proceeds to step S312.
The destination call in the car here refers to a destination call registered by the passenger pressing the destination button in the car, and hereinafter referred to as an in-car call in distinction from the hall call pressed by the passenger at the landing.
[0019]
The reason why priority is given to the in-car call in step S312 is as follows. For example, if a call in the car to the floor where the hall call occurred has already been registered in the lower car, the lower car is a crowded floor, so the lower car is stopped at the lower floor, and the upper car is stopped at the landing call floor. Then, in order to complete the in-car call, the lower car is again stopped at the landing call generation floor. Therefore, the boarding time will increase accordingly, and conversely, the service to the passenger and the operating efficiency of the car will often decrease.
[0020]
Therefore, when a car call is registered for the floor where the hall call is generated or the floor directly above / below it, the answering car is selected with priority given to the car call. In the previous example, even if the floor immediately below the floor where the hall call registration occurred is a crowded floor, the in-car call registration for the floor where the hall call registration occurred has been made in the cage below the assigned unit. For example, in order to complete the in-car call, the lower car is stopped at the floor where the landing call is generated.
[0021]
If no in-car call is registered on the floor where the hall call is generated and the floor directly above / below it, the process proceeds to step S34. In FIG. 2, it is a case where there is no in-car call, and the processing after step S34 is performed.
In step S34, the degree of congestion in the same direction as the traveling direction of the assigned unit (the direct upper floor and the direct lower floor are opposite) is detected in the upper floor / lower floor of the floor where the hall call is generated. In other words, the direction of travel of the assigned car coincides with the direction of the hall call. When the hall call is input with the up button and the down button, the direction of the hall call is upward if the up button is pressed, and down when the down button is pressed. In addition, when inputting with the destination floor button, it is determined by the direction from the landing call generation floor to the destination.
[0022]
Detection of the congestion level in step S34 is executed by the congestion floor determination means 14 in response to a request from the upper car / lower car allocation means 13. Here, it is assumed that the degree of congestion is simply set for each floor, and the degree of congestion of the directly upper floor / directly lower floor with respect to the floor where the hall call is generated is read out. In the case of FIG. 2, the hall call is generated on the 6th floor, so the congestion levels on the 5th and 7th floors are read. Since the direction of the hall call is upward, the degree of congestion in the upward direction on the fifth floor and the seventh floor is read out.
The congestion level for each floor may be set at the time of elevator installation, or may be set after elevator installation by a congestion level setting means (not shown). This will be specifically described in the embodiment.
[0023]
Further, the congested floor determining means 14 determines whether or not the floor immediately above / directly below the floor where the hall call has occurred is a congested floor based on the degree of congestion detected in step S34 (step S35). If the degree of congestion is expressed numerically, a threshold value is set in advance, and if it is equal to or greater than that value, it may be determined as a congested floor, and if it is less, it is determined as a non-congested floor. Further, when the congestion status of each floor is set as either crowded or non-congested, the crowded floor is determined based on this content.
[0024]
The result determined in step S35 is transmitted to the upper car / lower car allocating means 13. If the directly upper floor is a congested floor, the process proceeds to step S37, and if the immediately upper floor is a non-congested floor, the process proceeds to step S38.
In step S37, if it is determined in step S35 that the immediately lower floor is a crowded floor, the process proceeds to step S39, and if the immediately lower floor is a non-congested floor, it is determined to proceed to S310. Similarly, in step S38, it is determined from the result of step S35 that if the immediately lower floor is a crowded floor, the process proceeds to step S311, and if the immediately lower floor is a non-congested floor, the process proceeds to step S39. This determination is executed by the upper car / lower car assigning means 13.
[0025]
In step S39, the operation is performed when both the directly upper floor / directly floor are congested floors, or when both the directly upper floor / directly floors are non-congested floors. In this case, the car is given priority over either one of the floors. Since there is no merit to stop automatically, the stop car is decided by the usual method.
For example, if a rule is set in advance to stop the lower car on the odd floor and the upper car on the even floor, the lower car is stopped on the odd floor and the upper car is stopped on the even floor according to this rule. . Specifically, if the floor where the hall call occurs is the 6th floor, the 7th and 5th floors, which are directly above / below, are both congested or non-congested and can be given priority. Since there is no car, the upper car is stopped on the 6th floor and the lower car is stopped on the 5th floor.
[0026]
In step S310, since the directly upper floor is a congested floor and the immediately lower floor is a non-congested floor, it is determined that the lower car is stopped on the floor where the hall call is generated and the upper car is stopped on the upper floor. For example, as shown in FIG. 2 (c), if it is determined that the floor where the hall call is occurring is the 6th floor and the directly upper floor is a congested floor, the upper car is the 7th floor and the lower car is the 6th floor. Each will be stopped.
[0027]
In step S311, since the floor immediately below is a congested floor and the floor directly above is a non-crowded floor, it is determined that the upper car is stopped on the floor where the hall call is generated and the lower car is stopped on the lower floor. For example, as shown in FIG. 2B, when it is determined that the floor where the hall call is generated is the 6th floor and the immediately lower floor is a crowded floor, the upper car is the 6th floor and the lower car is the 5th floor. Each will be stopped.
[0028]
In the case of FIG. 2, when the lower car is on the fifth floor and the upper car stops on the sixth floor through the processing in any of the above steps S39, 310, 311, the lower car is on the sixth floor and the upper car is 7 It will be either when stopping on the floor.
The operations in steps S39 to 311 are all executed by the upper car / lower car allocating means 13.
[0029]
In this embodiment, by setting the congested floor / non-congested floor for each floor in advance, the car is stopped at the upper floor or the lower floor where there is no landing call at present but is easily congested. be able to.
[0030]
Embodiment 2. FIG.
In the first embodiment, it has been described that the degree of congestion for each floor has already been set. However, a user such as a building management operator may input the degree of congestion on each floor using an information input device. .
FIG. 4 shows the configuration of the elevator apparatus in this embodiment. In this embodiment, a user such as a building management operator has a congestion degree input means 15 for inputting the congestion degree of each floor. Thus, the configuration is different from that of the first embodiment. The congestion level input unit 15 is an example of the congestion level setting unit described in the embodiment.
The same reference numerals as those in FIG.
[0031]
FIG. 5 is a diagram illustrating an example of setting information of the congested floor / non-congested floor according to direction in each floor. This information is artificially set by the congestion degree input means 15 using an information input device. The setter considers the flow of people in the building, and if there are many elevator users in the upward direction on a certain floor, set the crowded floor in the upward direction of the corresponding floor, and conversely in the downward direction If there are many elevator users, the crowded floor is set in the downward direction of the corresponding floor. If no congested floor is set, the floor (by direction) is set as a non-congested floor. The above settings are made for each installation floor.
[0032]
Moreover, although the example here shows the setting in two stages of the congested floor / non-congested floor, it may be set as a congestion degree expressed numerically.
A congestion value is set by the input from the congestion degree input means 15, and this congestion value is utilized by the congestion floor determination means 14. This point is as described in the previous embodiment.
[0033]
In this embodiment, since the user inputs the degree of congestion or the crowded floor in advance, the car can be preferentially stopped for a specific floor at the user's intention.
[0034]
Embodiment 3 FIG.
In the first embodiment, it has been described that the degree of congestion for each floor has already been set. However, the degree of congestion for each floor may be determined by accumulating data indicating the usage status of the elevator for a certain period of time. Good.
FIG. 6 shows a configuration of the elevator apparatus according to this embodiment, and shows a configuration in which a 5-minute boarding load for each direction in each floor and its statistics are obtained to determine the degree of congestion for each floor. That is, the second embodiment is different from the first embodiment in that it includes a congestion degree detection means 16, a congestion degree statistics means 17, and a boarding load detection means 18. The congestion level detection unit 16, the congestion level statistics unit 17, and the boarding load detection unit 18 are examples of the congestion level setting unit described in the embodiment. The same reference numerals as those in FIG.
[0035]
The boarding load detecting means 18 detects the boarding load for 5 minutes for each floor in the up / down direction. The boarding load detection means 18 detects the boarding load generated for 5 minutes on a certain day as shown in FIG. The congestion degree statistic means 17 stores the 5-minute boarding load for one week and calculates the average value as shown in FIG.
[0036]
FIG. 7C shows the result of the congestion degree detection means 16 determining the degree of congestion for each floor and for each up / down direction based on the data obtained in FIG. 7B. In this example, the value of the floor having the highest average value of the riding load as shown in FIG. 7B is set to 100, and the other floors are set to 100, and each value is determined by the relative value of the floor. is doing. This calculates the relative value for all the floors in the up / down direction. If the value obtained here is equal to or greater than a specific reference value (20 in this example), the corresponding floor is a congested floor (the floor is underlined in the numerical value), and the floor is not applicable Is defined as a non-congested floor. Here, the first floor and the fourth floor are set as congested floors in the upward direction, and the fourth floor, the tenth floor, and the eleventh floor are respectively set in the downward direction. In FIG.7 (c), the congestion degree of a congested floor is underlined. According to the above procedure, the degree of congestion for each floor and for each up / down direction is determined.
[0037]
The above is merely an example, and the period for taking statistics may be set to one month, or the period of the boarding load detected at a time may be set to 10 minutes. Further, if the period for taking statistics is short, a method in which the values shown in FIG. Further, the value obtained in FIG. 7B as the degree of congestion may be used as it is. In that case, a method of changing the reference value (threshold value) of the congested floor according to the number of installed elevators is also conceivable. Accordingly, it is possible to appropriately determine the congested floor / non-congested floor according to the building environment.
[0038]
The congestion value set as described above is used in the congestion floor determination means 14. This process is as described in the first embodiment.
[0039]
In this embodiment, data indicating the usage of the elevator is accumulated for a certain period of time to determine the degree of congestion of each floor. Can be stopped and the waiting time can be shortened.
[0040]
Embodiment 4 FIG.
This embodiment is a further development of the detection of the degree of congestion of the third embodiment, and detects and sets the congestion situation in each time zone. Also in this embodiment, as shown in FIG. 6, it is executed by the congestion degree detection means 16, the congestion degree statistics means 17, and the boarding load detection means 18. The congestion level detection unit 16, the congestion level statistics unit 17, and the boarding load detection unit 18 are examples of the congestion level setting unit described in the first embodiment.
[0041]
FIG. 8 is a diagram showing a procedure for separately detecting and setting the degree of congestion for each floor and for each direction divided into time zones.
The boarding load detection means 18 detects the current time (step S81), and starts detecting the degree of congestion corresponding to this current time. Specifically, the boarding load is detected by the boarding load detection means 18, the boarding load statistical processing is performed by the congestion degree statistics means 17, and the congestion degree determination processing is executed by the congestion degree detection means 16. The specific processing contents are the same as those described in the third embodiment.
[0042]
In FIG. 8, the time zone is divided into eight ranges, and the degree of congestion is set for each time zone (steps S810 to S817). The degree of congestion in these eight time zones is stored.
If the congestion level determination means 14 has a request for detecting the congestion level, the congestion level corresponding to the time is read and the subsequent processing is executed. This point is as described in the first embodiment.
[0043]
In this embodiment, since the congestion level is set for each time zone, the car can be stopped according to the change in traffic flow in the building depending on the time zone.
[0044]
Embodiment 5 FIG.
In the third and fourth embodiments, when determining the degree of congestion on each floor, the average value of past boarding loads is used. Good. Also in this embodiment, processing is executed with the same configuration as in the third embodiment.
[0045]
Next, a procedure for setting the degree of congestion according to the immediately preceding congestion situation will be described below.
FIG. 9 is an example thereof, and is a flowchart showing a process of detecting the boarding load by floor for the past 5 minutes and calculating the degree of congestion for each floor / direction based on the obtained value.
[0046]
First, the boarding load detection means 18 detects the boarding load by floor for the past 5 minutes in step S91.
Next, proceeding to step S92, the congestion degree detection means 16 calculates the congestion degree of each floor based on the boarding load obtained at step S91. The method for calculating the degree of congestion is as described in the third embodiment. After step S92, the process of returning to step S91 is performed again. This is because the congestion degree is always calculated based on the latest information (ride load by floor), and the calculation period of the congestion degree is A short time such as every 1 minute or every 5 minutes is set to be executed.
[0047]
FIG. 10 is another example, and is a diagram showing the flow of processing when a hall congestion level monitor that detects a congestion situation at a hall is installed on each floor.
In step S <b> 101, the congestion level detection means 16 grasps the congestion status of each floor by using a monitor installed at the landing on each floor. For example, the congestion situation is grasped from values such as the number of passengers and density at each hall.
[0048]
However, since the up / down direction is not known at this time, the process proceeds to step S102, and the registration state of the hall call at each floor is detected. Then, using this detection result, the degree of congestion is determined as follows (step S103). If only the hall call in the upward direction is registered, all the values detected in step S101 are registered as the congestion value in the upward direction. When both the up and down direction hall calls are registered, the value detected in step S101 is divided into two equal parts, and the divided values are registered as the degree of congestion in the up / down direction. When only the downlink hall call is registered, all the values detected in step S101 are registered as the congestion value in the downlink direction.
[0049]
The processes in steps S101 to S103 described above are performed by the congestion degree detection unit 16.
When the calculated congestion level exceeds a predetermined threshold value, the congestion level detection unit 16 may register the floor as a congested floor and the other floors as non-congested floors.
[0050]
After step S103, the process of returning to step S101 is performed again. This is because the congestion degree is always calculated based on the latest information (ride load according to floor), and the calculation period of the congestion degree is A short time such as every 1 minute or every 5 minutes is set to be executed.
As described in the first embodiment, the congestion level set in this way is used for the determination process of the congested floor by the congested floor determination means. The description is omitted here.
[0051]
In this embodiment, since the congestion level is set according to the previous congestion situation and the congestion level is rewritten sequentially, it can be quickly performed on a crowded floor with specificity that causes many passengers to suddenly occur. Can respond.
In particular, according to the detection of the degree of congestion according to the procedure of FIG.
[0052]
Embodiment 6 FIG.
The elevator apparatus according to this embodiment shows another processing procedure when the degree of congestion is set as a numerical value, and a part of the procedure is different from the procedure of the first embodiment. In the first embodiment, when the congestion value exceeds the threshold value, it is determined that the floor is a crowded floor. In this embodiment, the higher floor is compared by comparing the congestion levels of the directly upper floor and the immediately lower floor. The one car is controlled to stop.
[0053]
FIG. 11 shows the configuration of the elevator control apparatus according to this embodiment. In the figure, the same reference numerals indicate corresponding parts, and the description thereof is omitted.
This embodiment is different in that it has a congestion degree comparison means 19 in particular. The congestion degree detection means 16, congestion degree statistics means 17, and boarding load detection means 18 are the same as those shown in the previous third to fifth embodiments, and the degree of congestion for each up and down of each floor is set by these. The
[0054]
FIG. 12 shows the control procedure of this embodiment.
First, when a hall call button is pressed at an elevator hall on a certain floor and a hall call is generated, the hall call registration means 11 registers the hall call (step S121).
The information of the hall call registered by the hall call registration means 11 is transmitted to the car number assignment means 12. In the case of an elevator system provided with a plurality of units, a unit that responds to the hall call is selected by the unit allocation means 12, and if only one elevator system is installed, that unit is caused to respond to the hall call. As a result, the number assigned to the hall call is determined (step S122).
[0055]
Next, the upper car / lower car assigning means 13 has the destination call in the car on the floor where the hall call registered in step S121 or the floor directly above / below it is registered in step S121. Is determined (step S123). If the number assigned in step S122 does not have a call in the car on the floor where the hall call is generated or directly above / below it, the process proceeds to step S124, and if it has, the process proceeds to step S1210. If the process proceeds to step S1210, the car stops in response to the in-car call.
[0056]
If the car call is not registered on the floor where the hall call is generated and the floor directly above / below it, the process proceeds to step S124. In step S124, the degree of congestion in the same direction as the traveling direction of the assigned unit (the uppermost floor and the lowermost floor are reversed) is detected for the upper floor / lower floor of the floor where the hall call is generated. The traveling direction of the assigned car corresponds in other words to the direction of the hall call.
The congestion level detection is executed by the congestion floor comparison unit 19 in response to a request from the upper car / lower car allocation unit 13. In FIG. 12, the degree of congestion on the upper floor _U , K _L It is described. Here, the degree of congestion is determined according to the above-described third to fifth embodiments.
[0057]
The congestion floor comparison means 19 detects the congestion level of the immediately above floor / directly below floor, and then detects the congestion level K of the immediately above floor detected in step S125. _U And the degree of congestion K on the floor directly below _L Compare The crowded floor comparing means 19 notifies the comparison result to the upper car / lower car allocating means 13, and the upper car / lower car allocating means 13 determines the degree of congestion K on the upper floor. _U Is the degree of congestion K on the floor directly below _L If so, step S126 is performed, otherwise step S127 is performed.
[0058]
When proceeding to step S126, the degree of congestion K on the upper floor _U Is the degree of congestion K on the floor directly below _L Therefore, the upper car / lower car allocating means 13 controls the corresponding car so that the lower car of the car is stopped at the landing call registration floor and the upper car is stopped immediately above.
[0059]
If it is determined in step S127 that the degree of congestion between the directly upper floor and the immediately below floor is equal, the upper car / lower car assigning means 13 executes step S128, and otherwise, executes step S129. In step S128, since the congestion levels of the directly upper floor and the immediately lower floor are the same, the upper car / lower car allocating means 13 cannot determine which of the congestion levels is higher. In this case, normal control is performed, and in this example, control is performed so that the lower car is stopped on the odd floor and the upper car is stopped on the even floor.
[0060]
In step S129, since the congestion level of the immediately lower floor exceeds the congestion level of the immediately above floor, the upper car / lower car allocating means 13 stops the upper car at the landing call registration floor and the lower car at the immediately lower floor. To control the corresponding machine.
[0061]
In this embodiment, the degree of congestion is compared between the directly upper floor and the immediately lower floor, so that the car is stopped at the higher congestion level. The car can be preferentially stopped on a crowded floor, and the service can be improved even for a floor with a low degree of congestion. Moreover, even when both the directly upper floor and the directly lower floor can be recognized as the congested floor, the average waiting time can be shortened by stopping the car in a higher congestion level.
[0062]
The comparison of the degree of congestion between the directly upper floor and the directly lower floor as in this embodiment can be applied instead of the process of step S39 in FIG. When both the directly upper floor and the directly below floor are congested as in the case of proceeding to step 39 in FIG. 3, the processes of steps S124 to S129 are executed when both the directly above floor and the immediately below floor are not congested (the directly above floor and Cars may be assigned by comparing the degree of congestion on the floor immediately below. In this case, it is necessary to provide the congestion degree comparison means 19 in the configuration of the first embodiment.
[0063]
In the above embodiment, the degree of congestion between the directly upper floor and the immediately below floor is examined, because the upper car and the lower car of the above-described embodiment are stopped on the adjacent floors.
In the car of the above-described embodiment, the upper car and the lower car are stopped on the adjacent floors, but the upper car and the lower car may be connected to each other with an interval of one floor or more. .
Even in this case, the main points are the floor where the lower car stops when the upper car of the double deck elevator stops at the landing call generation floor, and the floor where the upper car stops when the lower car stops at the landing call generation floor. It is sufficient to check the degree of congestion.
[0064]
【The invention's effect】
The double deck elevator according to the present invention is a double deck elevator in which an upper car and a lower car are vertically connected in a hoistway, and a hall call registration means for registering a hall call and a hall call registration registered by the hall call registration means. A first floor where the lower car stops when the upper car is stopped on the floor, and a second floor where the upper car stops when the lower car is stopped on the landing call generation floor The crowded floor determining means for determining the crowded floor from the first floor and the second floor according to the degree of congestion with the upper floor and the lower car on the crowded floor and the landing call generation floor Since it has a car allocating means for allocating, it is possible to shorten the waiting time for a hall call that will occur in the future for a floor with a high degree of congestion.
[0065]
In addition, when the crowded floor determining means determines that the first floor and the second floor are not crowded floors, the car allocating means determines the hall call based on a predetermined rule. Since the upper car or the lower car is stopped on the generation floor, it is possible to operate with priority given to a predetermined rule.
[0066]
The double deck elevator according to the present invention is a double deck elevator in which an upper car and a lower car are vertically connected in a hoistway, and a hall call registration means for registering a hall call and a hall call registration registered by the hall call registration means. The degree of congestion of the first floor where the lower car stops when the upper car is stopped on the floor, and the second car where the upper car stops when the lower car is stopped on the landing call generation floor A congestion degree comparison means for comparing the degree of congestion with the first floor and the second floor, and determining a crowded floor from the first floor and the second floor as a crowded floor; and Since the upper car and the lower car are assigned to the landing call generation floor, the waiting time is reduced with respect to a floor call that will occur in the future for a highly congested floor. Rukoto can.
[0067]
In addition, when a car call for stopping at any one of the landing call generation floor, the first floor, and the second floor is not registered in the upper car or the lower car, the car Since the assigning means assigns the upper car and the lower car, the operation efficiency can be improved by giving priority to the in-car call.
[0068]
Furthermore, the degree of congestion with respect to a plurality of floors is set for each of the upward direction and the downward direction, and the degree of congestion in the same direction as the direction of the hall call among the congestion degrees set for the plurality of floors is set to the first level. Since the degree of congestion of the first floor and the second floor is used, the driving efficiency can be further improved and the waiting time can be shortened.
[0069]
Furthermore, since it has the congestion degree input means which inputs the congestion degree with respect to several floors, a user can set a congestion degree arbitrarily.
[0070]
In addition, since the degree of congestion is calculated based on the number of passengers in the past on multiple floors, the degree of congestion can be set according to the actual driving situation in the past, and the car assignment can be made more promptly. it can.
[0071]
Furthermore, since the degree of congestion is calculated for a plurality of time zones, it is possible to cope with the case where the congestion situation changes depending on the time zones.
