DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator system for controlling the operation of an elevator, and more particularly to an improvement in an elevator system suitable for a small number of elevators.

[0002]

2. Description of the Related Art In an elevator operation management system, it is the greatest problem to reduce and equalize the waiting time of each user.

Various techniques have been used to address this problem.

[0004] Initially, the service area of each elevator was determined according to each position of the plurality of elevators, and the elevators were arranged at equal intervals as much as possible.
After that, various factors were evaluated for each hall call generated by the development of microcomputers, and a hall call allocation method for allocating an optimum elevator for each hall call came to be used.

[0005] These control systems are methods for optimally servicing hall calls that occur irregularly. Further, as a service that provides a specific traffic flow, there is a service in which a specific service elevator handles only a specific hall call for a divided express operation at the time of commuting or a specific traffic demand.

Japanese Patent Application Laid-Open No. 63-247279 discloses a configuration in which a specific elevator serves a specific traffic demand.
There is JP-A-63-247280. Japanese Patent Application Laid-Open No. 63-247279 discloses that a specific service unit accepts only a car call on a specific floor when a specific high demand occurs at a preset time, so that a specific floor, such as at lunch or leaving work, can be used. During times of heavy demand, the elevators on specific floors are designated, and the elevators serve the demands for specific floors, thereby shortening the round-trip time of specific units and increasing the demand for floors. It is stated that the service will be focused. Further, JP-A-63-247280 discloses JP-A-63-247280.
In addition to No. 7279, multiple elevators are divided into two groups: elevators that provide service on all floors and elevators for specific floors. Elevators for specific floors have special indicators and special buttons, and are set in advance. At that time, it is stated that the elevator for the specific floor indicates that only the specific floor is to be reached, so that the passenger can be serviced without hesitation.

[0007]

The hall call assignment system and the zone system are control methods suitable for a case where a hall call is generated irregularly, and the floor and the destination floor where the hall call is generated are almost determined. Not enough to service traffic demand.

[0008] It is required to provide a good service even in a high demand where it is difficult to cope with the hall call assignment system and the like, and the prior art disclosed in the above-mentioned publication is intended to solve these points. However, it has been found that, for example, when demand is concentrated from each floor to the first floor during lunch, elevators are full on the upper floors, and the service from the middle floors to the lower floors may be significantly reduced. In addition, the above-mentioned conventional example has a time and a specific destination floor in advance.
It was also found that the specific elevator could not cope with the demands of different destinations and could not cope with the changing demands.

An object of the present invention is to solve such a problem,
It is an object of the present invention to provide an elevator apparatus that efficiently manages unpredictable changes and deviations in traffic demand.

[0010]

SUMMARY OF THE INVENTION In one aspect of the present invention, an elevator is serviced only to a plurality of specific floors in response to a scheduled condition.
In one embodiment of the present invention, when it is detected that the traffic demand in the building is biased, any elevator is allowed to share the biased demand, and the other elevators handle the other or the entire demand. Change sharing.

[0011]

With this configuration, it is possible to allocate elevators suitable for the traffic flow at that time, and it is possible to improve the overall service. Also, according to a preferred embodiment of the present invention, the traffic flow is divided into a specific high demand traffic flow and a normal traffic flow, and the service elevator is divided into an elevator serving the specific high demand traffic flow and the normal traffic flow. By providing services separately to the elevators to be serviced, it is possible to prevent the services from being biased to the traffic demand.

Furthermore, in another preferred embodiment of the present invention, elevators serving other floors also do not provide services between high demand floors which require a long time to get on and off, so that the round trip time is shortened and the overall waiting time is reduced. Time is reduced. Further, it is possible to prevent the floors before and after the high-demand floor from being occupied by the full occupancy, thereby improving the overall serviceability.

The hall call allocation method of allocating hall calls using recent comprehensive evaluation is used to optimally service irregularly generated hall calls as described above. For this reason, it was not suitable to service high demand generated between specific floors. In the case of group management control of four or more elevators, while one elevator is serving high demand between specific floors, another elevator is
Since other floors can be serviced, even if the hall call assignment method is adopted, sufficient performance can be exhibited unless there is a particularly large demand.

However, according to a simulation performed by the inventor who applied this allocation method to an elevator having only two or three elevators, if the demand concentrates on the first floor, such as at lunch, the upper floor is required. If the number of passengers is large, it will be full on the way, and services on subsequent floors will not be possible. Also, even if it is not full, it takes much longer to get on and off in a crowded state than in an empty state, so the round-trip time of the elevator becomes longer and the waiting time increases, and during this time the number of customers on each floor increases In addition, a vicious cycle occurs in which the elevators operate in a crowded state.

[0015] Even with four or more elevators, most elevators provide services between high-demand floors, especially when there is a high demand, when there is a large shift in demand, or when there are many service floors. . For this reason, services on floors other than the high-demand floor decrease, and the round-trip time increases due to getting on and off the bus with the high-demand floor congested.

Therefore, the service between the high demand floors is performed by an arbitrary elevator. For example, 1
If there is a large demand on the 10th and 9th floors to the 1st floor in a 0-story building, the elevator will be congested up to the 9th floor and the 8th floor will remain.
The service on the floors after the floor is reduced. Therefore, by detecting this demand and setting any of the plurality of elevators to the piston operation from the ninth floor to the first floor, 1
The waiting time between the 0th and 9th floors and the 1st floor can be shortened, and other elevators can be provided with services on other general floors, thereby preventing an increase in the getting on and off time when the vehicle is full or crowded.

As a result, it is possible to reduce the round-trip time of all elevators, and to improve serviceability such as reduction of waiting time for both specific floor-to-floor demand and general demand.

[0018]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is an overall configuration diagram of the present invention. Information from the hall call buttons 101 to 10n is collected by the hall call collection device 31 in the group management control device 3 through the hall call transmission line 2, and together with the car information of the car information collection device 32, the assignment control device 33 and the traffic flow judgment device. 34. The information of the car call buttons 41 to 44 is stored in the car call transmission line 51.
Are transmitted to the car control devices 61 to 64 through .about.54, and are sent to the car information collecting device 32 and the assignment control device 33 through the transmission line 7 together with car position information of each car. The assignment control device 33 determines an assigned elevator to service the hall call based on the information, and sends an assignment signal to the car control devices 61 to 64 via the transmission line 7. The car control devices 61 to 64 control the motors 81 to 84 according to the assignment signals, and the motors 81 to 84 operate the cars 111 to 114 by the hoists 91 to 94 to provide services for hall calls and car calls. . 121 to 124 are counterweights. The traffic flow determining device 34 determines the traffic flow for each floor from the information sent from the hall call collecting device 31 and the car information collecting device 32. The traffic flow for each floor is calculated based on the estimated traffic volume to the destination floor, whether there is a full load, waiting time, boarding time, occupancy rate at arrival or departure, whether there is a long wait, Whether or not it has occurred. Traffic judgment device 34
Sends a schedule operation command to the assignment control device 33 when it detects that a high demand has occurred or that the service has declined, such as a long wait at another floor. The assignment control device 33 selects a schedule drive suitable for the traffic flow according to the determined traffic flow condition, displays that the scheduled drive is to be performed on the landing display devices 131 to 13n, and when the car becomes empty, or After the end-floor service, perform scheduled operation. In the scheduled operation, one or more car units are selected and rushed to the floor where high demand is occurring. At this time, the main destination floors estimated from the traffic flow are displayed on the landing display devices 131 to 13n. When the elevator reaches the high demand occurrence floor, the car call to the estimated destination floor is automatically registered, and after the user gets on the vehicle, goes straight to the estimated destination floor.

FIG. 2 is a flowchart of the present invention. The following is performed as part of the normal assignment control. First, the traffic flow determination device 34 measures the traffic flow of each floor based on the collected hall call information, car information, and the like (201), and then determines the traffic flow (202). Further, it is determined whether or not the occurrence of a high demand or a lowered service floor is detected (203).
If high demand or service degradation has occurred, the traffic flow judging device 34 issues a schedule operation command to the assignment control device 33 (204). If not, control returns to normal assignment control (212). Upon receiving the schedule operation command, the assignment control device 33 selects a schedule operation suitable for the traffic flow based on the traffic flow determined by the traffic flow determination device 34 (205). Next, a predetermined elevator is selected and disconnected from the target of the normal assignment control (206), and the landing displays 131 to 13n indicate that the elevator will perform the scheduled operation. At this time, the landing indicators 131 to 13n on the high demand floors indicate that the elevator is a straight line from this floor to the main destination floor estimated from the traffic flow. After the elevator is emptied or services the end floor, it goes straight to the high demand floor (207).
Upon reaching the high demand floor, a car call to the main destination floor estimated from this floor is registered (208), and the vehicle goes straight to the destination floor (209). Next, it is checked whether or not the high demand has been resolved (210). If the high demand has not been resolved, the process returns to step 207, and the above steps are repeated. Then, the operation returns to the normal operation (212).

FIG. 3 is an explanatory diagram of the present invention. FIG. 3 (a)
Shows the movement of the elevator at the time of scheduled operation in the case of a two-door elevator in a building with a 6th floor. FIG.
(B) shows the traffic flow in this case. The traffic flow is such that there are many downstream traffic flows, but there are also some upward traffic flows.
There are many traffic flows downstairs and 5th floor. In such a case, the down-facing elevators are loaded in large quantities from the 5th and 6th floors and become full, and it becomes impossible to service down-facing calls on the 4th and lower floors. In particular, in this traffic flow, there is a call on the 5th and 6th floors, so it is not possible to reverse on the middle floor,
The service on the middle floor is significantly reduced. In extreme cases, there is a risk that no services will be provided below the fourth floor at all until there is no downward demand on the fifth or sixth floor. In addition, all elevators are stopped at each floor, and the round time, which is the time the elevator makes a round from top to bottom, increases, and both the waiting time and the boarding time increase. In addition, even if the group is not full, some group users may not be able to ride, especially if the number of riders is small. In this case, immediately after the elevator starts, the hall call button is pressed to call the next elevator again. The occurrence of a wasteful call without getting on / off even when the vehicle stops in this way further increases the round trip time, and further worsens the waiting time and the boarding time. When this situation becomes constant, the user going down on the fourth floor pushes the call button up, goes to the top floor once, and goes down without going down to use the elevator. In this case, the congestion is further increased, and a waiting time is further increased since an originally useless hall call is made. This traffic flow is a traffic flow at the time of lunch in a certain building, and the main traffic flow is a traffic flow from the sixth floor or the fifth floor where the office is located to the first floor serving as a standard floor for eating. Therefore, the traffic flow in FIG. 3B can be separated into traffic flows from the fifth and sixth floors to the first floor and other traffic flows as shown in FIGS. 3C and 3D. Therefore, one elevator is dedicated to the service of the traffic demand from the fifth and sixth floors to the first floor, and the remaining elevators are used to service other traffic flows. In this example, car A is an elevator dedicated to traffic flow from the fifth and sixth floors to the first floor, and car B is an elevator that services other traffic flows. In this way, the users on the fifth and sixth floors go directly to the first floor after riding, so they do not stop on other floors,
The boarding time is shortened and the waiting time is also shortened because one rounding time is shortened because the hall does not respond to hall calls on other floors. As for the traffic flow on the other floors, the situation that the service is not provided due to the fullness of the fifth and sixth floors does not occur. In addition, there is no longer a service that goes down on the 5th and 6th floors, which took many hours to get on and off.
One round time is shortened, and a reduction in waiting time can be expected.

Further, when the fifth and sixth floors become more crowded and the sixth floor becomes full and the fifth floor cannot be serviced, the traffic flow is further increased as shown in FIGS. 3 (g) and 3 (h). Separated from the 5th floor downward and the 6th floor downward, as shown in FIG.
After answering the call on the 6th floor down, go straight to the first floor,
Thereafter, the user may go straight to the fifth floor to service a downward call on the fifth floor.

FIG. 4 shows one embodiment in the case of one unit. The traffic flow judging device 34 in the car controller 61 receives the car information from the hall call buttons 101 to 10n, the car call button 41, the load sensor in the car, etc.
1. When the traffic flow is received from the car information collecting device 32 to determine the traffic flow and a high demand floor or a low service floor is detected, a schedule operation command is sent to the operation control device 611, and the operation control device 611 controls the motor control device 612. And then go into scheduled operation.

FIG. 5 is an explanatory diagram of an example of the schedule operation in the case of one vehicle. The traffic demand in (a) is divided into demand from the sixth floor to the first floor as in (b) and other demand as in (d). Therefore, in the case of one vehicle, the first round trip as shown in (c) is a period during which the high demand floor of (b) is served, and the second round trip is as a period during which the other floors are serviced as shown in (e). This is achieved by alternately performing at a fixed rate.

FIG. 6 is a flowchart of the schedule operation for one vehicle. When a high demand floor or a low service floor is detected (601), the floor on which the scheduled operation is to be performed is checked (602), and the effect of the scheduled operation is displayed on each floor (603). In the case of one unit, a special display is rarely installed, and therefore, in many cases, an express display is performed. Next, in the first period, the floor to be serviced by the scheduled operation is displayed (604), and the service floor goes directly to the high demand floor (605), and then from there, goes directly to the main destination floor (208). Provides traffic flow services. In the next period, the general floors other than the high demand floor will be served. At this time, a message indicating that a general floor is to be serviced is displayed (60).
7). In addition, it responds to calls on floors other than the high demand floor (60
8) When it reaches the terminal floor in response to all calls except the high demand floor, it is checked whether the high demand state has been resolved (21).
0), if not resolved, repeat from (604) onwards,
If it has been canceled, the operation returns to the normal operation (212).

FIG. 7 is a flowchart of the high demand measurement. First, during normal operation, the waiting time for each floor of the elevator, the riding time, the riding rate, the number of hall calls, the number of passengers, the number of people getting off, the number of passengers, the number of passengers, the useless calls, etc. are measured for each round of the elevator (202-1). It is checked whether or not there is a full call, the passage of hall calls, unnecessary calls or long waits (202-2).
If not, normal operation is continued. If it does not occur, return to normal operation. If it does occur, whether it is caused by high demand, based on the time when the full capacity, passage of hall calls, useless calls and long waits occurred, and on the floor where it occurred Is checked (202-3). If it is not due to high demand, normal operation is continued, and if it is due to high demand, the assignment control unit 33 operates the operation control unit 611.
, A schedule operation command is transmitted to perform the schedule operation (202-4).

In a normal traffic flow, it is often not possible to estimate from which floor a user gets down to which floor. However, when high demand is generated, a floor where an event or the like is located and another floor is located. The flow for moving to a specific floor, such as lunch or leaving the office, or the traffic flow from a specific floor to another floor such as when going to work, so the number of people getting on and off while the elevator goes up and down one round for each elevator You can know the main traffic flow if you record in. As a method for checking whether or not a long wait in (203-3) of FIG. 7 is caused by high demand for performing the scheduled operation of the present invention, for example, as shown in FIG. It is sufficient to prepare a table based on the occurrence items and determine whether or not to perform the scheduled operation by referring to this table. This table is packed with elevators,
It may be simplified such as a long wait, an occurrence time zone, an occurrence floor, and the like. The table may be created in advance, or may be created after operation by learning or the like.

FIG. 8 is a flowchart for determining the driving method. First, the floor on which the scheduled operation is to be performed and the destination floor therefrom are determined from the occurrence floor, the occurrence time of a long wait or the like measured at the time of high demand measurement, the occurrence time, and the number of people getting on and off each floor (205-1). The floor on which the scheduled operation is to be performed is determined, for example, as follows. In a seven-story building, it is assumed that the time of lunch is during the lunch time, and that the building is full on the sixth floor, and the fifth and subsequent floors are fully packed. The sixth and seventh floors are high demand floors according to the present invention, and the fifth and subsequent floors are service reduction floors. In the case where the learning function is provided, the determination is made by referring to a table created in advance, and in the case where the learning function is not provided, it is determined from the past learning result. The learning function here does not have to be very detailed. For example, it is only necessary to record the car call floor immediately after the high demand floor hall call service for each time zone. Next, the number of elevators performing the scheduled operation is determined from the learning result or the table (205-2). 1
In the case of a unit, the ratio of the service of the high demand floor and the service of the general floor is determined instead of the number of units. This ratio may be, for example, one high demand floor service (up and down one round) and two general floor services (up and down two rounds) per hour. The method of moving each elevator is determined by referring to a table prepared in advance or created based on simulation results (205-3).

FIG. 9 is an explanatory diagram showing an example of a scheduled operation. (A)-(d) shows the traffic flow, and (e)-(f)
Shows an example of scheduled driving in each traffic flow. (A) is a traffic flow that concentrates from a high-demand floor to a reference floor, such as when the event is completed at the first half of lunch, at the time of leaving work, or at the roof of a department store. (B) is a case where the high demand floor has two floors.
(C) is a traffic flow that scatters from one floor to another floor, such as when going to work. Unlike the conventional express train at work, the present invention does not have to always determine that high demand will occur on the reference floor.Moreover, not only during a fixed time zone, but when high demand occurs, the overall efficiency will be reduced. There is an effect that schedule driving can be performed in consideration of the above. In particular, it is possible to prevent a situation where the departure floor becomes full at the time of commuting and the service upward in the middle floor is significantly reduced. (D) is a case where the user moves from a specific floor to a specific floor which occurs when the user goes to another event venue after the end of the conference or the event.
(E) is an example of the scheduled operation in the case of the traffic demand of (a). It can be seen that the main traffic demand is the traffic demand from the 6th floor to the 1st floor, so that the No. A service is a direct round trip between the 6th floor and the 1st floor to service this demand, and the No. B service the other demands. (F) is the case where the main traffic demand extends over the second floor as in (b). In this example,
The traffic demand from the fifth and sixth floors to the first floor is the main traffic demand.
Also in this case, the main traffic demand is serviced to the car A and the other traffic demand is serviced to the car B. In this example, the car A stops in the order of the sixth floor and the fifth floor and then goes straight to the first floor. However, when the demand further increases and the service of the fifth floor is reduced, the car A is stopped at the sixth floor and the sixth car is stopped. It detects that the floor is full and goes straight to the first floor to drop off passengers, then goes straight to the fifth floor to provide services on the fifth floor. Not only when the sixth floor is full but also when the number of passengers on the fifth floor is smaller than expected, it is determined that high demand has occurred and this driving is performed. This extreme case is where no one gets in when arriving at the hall call. (G) is, like (c),
The main traffic demand is an example of providing a traffic demand in which a traffic flow between each floor is somewhat mixed with a traffic demand distributed from a reference floor to another floor at work. In such traffic demand, when the traffic demand between floors exceeds a certain ratio, the elevator stops at each floor both up and down, and the round-trip time increases and a long wait occurs. In addition, climbing on an intermediate floor takes a long time to get on and off the crowded elevator, and service on the floor near the reference floor is significantly reduced unless there is a car call. Therefore, the car A is dedicated to the service for the demand distributed from the base floor to each floor, and the car B is made to respond to the call of the other floor. In this way, the service can be improved as a whole. In this case, the service on the reference floor seems to be reduced. However, in traffic demand where this driving method is effective, one round time of Unit A serving the reference floor can be halved. The same service is possible. (H)
This is an example of a case where a service in which traffic demand from a specific floor to a specific floor overlaps general traffic demand as shown in FIG. No. A services the traffic demand from the specific floor to the specific floor, which is originally a different traffic flow, and services the general traffic demand from the B car, thereby eliminating waste of getting on and off and the concentration of elevators. Has the effect of not having to travel in the hall by preparing a dedicated car, and has the effect of shortening the boarding time. Since congestion by users can be avoided, the service can be improved as a whole.

FIG. 10 shows an example of the operation method for one vehicle. In the traffic flow shown in FIG. 9A, as shown in FIG. 9A, a direct service from the sixth floor to the first floor is performed in the first period, and services on other floors are performed alternately in the next period. By repeating this, the same effect as in the case of FIG. 9E can be exhibited. In the case of FIG. 9 (b), as shown in FIG. 10 (b), this is divided into a period in which the fifth and sixth floors are serviced and a period in which the other floors are serviced, and this is repeated alternately. In the case of further congestion, as shown in FIG. 10C, the service is divided into three periods: a period during which the sixth floor is serviced, a period during which the fifth floor is serviced, and a period during which the other floors are serviced. FIG.
In the case of (d), as shown in FIG. 10 (d), the riding time and the occupancy rate can be reduced by dividing into a period in which a specific floor is serviced and a period in which another floor is serviced.

FIG. 11 shows an embodiment in which learning is performed. The learning device 35 learns information from the hall call collection device 31 and the car information collection device 32, and a learning table 36.
Create The learning table 36 stores the waiting time for each floor, the elevator, the number of occurrences of hall calls, the boarding time,
The hall calls, occupancy rate, number of passengers, occurrence of occupancy, number of passes, number of unnecessary calls, etc. generated after arriving at each floor and arriving at the next floor are recorded and compiled into data for each unit time and floor. And record by time of day. According to the present embodiment, the accuracy of estimating the main destination floor or the like when a certain time zone or an event occurs can be improved, so that the accuracy of useless scheduled operation is improved, and efficient operation can be performed.

FIG. 12 shows an example of the learning table 36.
(A) is the waiting time for each floor, the number of hall call occurrences,
Ride time, hall calls that occurred after arriving at each floor and arrived at the next floor, boarding rate, number of people getting on and off, full load, number of passes, number of useless calls, etc., and the main destination floor for each floor Recorded separately. For simplicity, the occurrence time zone, the occurrence floor, and the destination floor for each floor may be (b). In this case, what is changed according to the learning result is the high demand floor and its destination floor, and the basic movement when performing the scheduled operation is not changed.

FIG. 13 shows an embodiment in which a simulation is performed based on the learning result. The simulation device 37 performs a simulation based on the contents of the learning table 36, which is the learning result of the learning device 35, by changing the number of schedule operations for each time zone, the situation at that time, the traffic flow, and the number of floors operation. , Find a suitable schedule operation for each. This is registered in the schedule operation table 38 corresponding to each learning operation table,
When the traffic flow judging device 34 detects that a situation in which a scheduled operation should be performed has occurred, a schedule suitable for the determined traffic flow, operation status, time, and floor is found from the schedule operation table 38 and the scheduled operation is performed. Do. According to the present embodiment, a schedule operation suitable for each condition different for each building can be prepared by simulation in advance, so that more efficient operation is possible.

FIG. 14 shows an embodiment in which a schedule is determined in advance. The schedule described so far is to perform a scheduled operation that detects that a certain situation has occurred and resolves it.
In such a method, there is a delay in coping with the problem. For a traffic flow constantly occurring at a specific time, it is possible to eliminate a control delay by starting a scheduled operation at that time in advance. In this case, the occurrence time of a specific traffic flow is detected by the learning device, and a scheduled operation corresponding to the time is determined in advance, and the scheduled operation is automatically started at that time. is there. The learning device 35 records the time zone in which each traffic flow occurs in the learning table 36 by the clock 39, and the assignment control device 33 controls the learning table 3
The schedule operation suitable for the time zone is performed with reference to the schedule operation table 38 based on the data of 6 and the clock 39. According to the present embodiment, a scheduled operation can be executed in advance before a problematic event occurs, so that a quick response can be made.

FIG. 15 shows an embodiment in which a schedule is determined in advance based on a simulation result.
The simulation device 37 simulates various schedule operations using the data of the learning table 36 based on the learning result of the learning device 35,
A suitable driving method is determined for each time zone, for each traffic demand, and for each event, and is written in the schedule driving table 38. The assignment control device 33 includes a clock 39 and a learning table 3
Based on the output of No. 6 and the situation of the halls and cars, schedule operation suitable for the time zone and situation is scheduled.
Select from 8 and operate. According to the present embodiment, the effectiveness can be confirmed in advance by simulation, so that more reliable operation control can be realized, and it is possible to predict how the flow of people changes due to scheduled operation. In addition, if the traffic flow is significantly different from the predicted traffic flow after the scheduled operation, it is judged that the traffic flow is different from the traffic flow assumed in the current scheduled operation, and by returning to normal operation, improper operation can be performed. Can be eliminated.

FIG. 16 is a flowchart when a schedule to be executed at a certain time is determined in advance. First, the assignment control device 33 detects that a predetermined time has come by the clock 39 (161). Next, the traffic flow is determined (202), and whether or not the traffic flow is expected in the time zone is checked by referring to the data of the learning table 36 (162). If the traffic flow is different from the expected traffic flow, the operation returns to the normal operation. If the traffic flow is the expected traffic flow, the steps (204) and subsequent steps are executed as in FIG. Returning to normal operation when traffic flow is different from the expected
5 is particularly effective when performing a simulation, but it can be realized without performing a simulation as long as it can be determined to the extent that a call is generated at a certain floor.

FIG. 17 shows an example of the schedule table. (A) is an example in which a destination floor, a control method, and a number are searched for occurrence events such as a time zone, a floor, and high demand;
(B) is an example in the case of searching by time zone and occurrence event.

FIG. 18 shows an example of setting a service rate. In the embodiments described above, the main focus is on preventing service degradation during times of high demand, etc., so that the services on each floor are made as uniform as possible. It is also possible to give priority to the service on the floor while not lowering the service on the other floors too much. The service rate is set by the service rate setting device 15, and the simulation device 37 finds a control method capable of realizing the service rate by simulation and writes it in the schedule operation table 38.
The assignment control device 33 controls the schedule by selecting a schedule from the schedule operation table 38 for each traffic flow and time zone so that the set service rate can be realized.

FIG. 19 shows an embodiment in which the destination of a passenger is known. When the landing buttons 141 to 14n are installed at the landings, if there are a plurality of main destinations on the high demand floor, it is possible to further improve the efficiency by preparing a car for each destination.

FIG. 20 shows an example of the express display. (A) to (e) are examples of displaying on floors and elevator landing displays for performing scheduled operation, and (f) and (g).
Is an example of displaying at a landing other than the elevator that performs the scheduled operation. (A) is an example of simply displaying express. (B) shows the floor between the service floors going straight
This is an example in which a display is made such as going straight to the sixth floor and the first floor.
(C) is an example displayed when entering the scheduled operation. (D) is an example showing the destination when entering the scheduled operation. (E) is an example schematically showing a service floor and a destination floor.

(H) is an example in which the display of the other elevator on the floor performing the scheduled operation indicates which elevator performs the scheduled operation. (I) is an example in which the user who goes to the scheduled driving service is guided to the elevator that performs the scheduled driving.

FIG. 21 shows an example in which an express is displayed by the indicator. In (a), there is an elevator on the third floor showing the display of the indicator before the scheduled operation is started, and the lamp on the third floor is lit. (B) and (c) are 6
This is an example in which an express operation is performed between the first floor and the first floor. The express display is turned on, and the first and sixth floors serving as service floors are blinked.
(C) shows a state where the user has arrived at the sixth floor. (D)
Is an example of a case where a scheduled operation is performed between the first floor and the sixth and seventh floors. The first floor, sixth floor, and seventh floor, which are service floors, are blinked. (E) and (f) show an example in which the scheduled operation is performed between the first floor and the sixth and seventh floors, but the period for servicing the sixth floor and the period for servicing the seventh floor are separated as shown in FIG. is there. First, the seventh floor and the first floor to be serviced are blinked and displayed, and when this service is completed, this operation is repeated until the scheduled operation for blinking and displaying the sixth floor to be serviced next instead of the seventh floor is completed. (G) and (h) show a case where there are two display lamps, express and normal. As shown in FIG. 4, when the scheduled operation is performed by the single elevator, the period in which the express operation is performed by one elevator and the period in which the normal service is performed alternately exist. This is an example in which a normal display is performed during normal service operation so that it is possible to understand what kind of operation is currently being performed.

FIG. 23 is a flowchart in the case of a diamond display. The process up to making a car call on the main destination floor (208) is performed in the same manner as in FIG. 2, and upon arrival, the system waits until the time indicated on the diagram (231), and thereafter (20)
After 9), the same operation as in FIG. 2 is performed. According to the present embodiment, the waiting time increases since the user waits until the time when the diamond is displayed, but the user does not go earlier than the diamond, so that the user can effectively utilize the margin before the arrival time.

FIG. 24 shows an example of a simple schedule operation. In each flow of this figure, steps a1 to f
Reference numeral 1 denotes a step of detecting an event that triggers this flow. FIG. 7A is a flowchart in the case where a scheduled operation is performed by detecting a packed departure.
First, it is detected that the vehicle is empty at the time of arrival and is full at the time of departure (a1). Next, the main destination floor is detected (a2). Further, it is detected whether or not the call for the packed floor is registered immediately after departure (a3). If there is no call registration, normal operation is performed,
When the call is registered, a direct operation is performed between the packed floor and the main destination floor (a4). Next, it is detected whether or not the demand on the packed floor has disappeared (a4).
4) Repeat the subsequent steps. This embodiment has the effect of improving the service of this floor, assuming that the full-occurrence floor is a high-demand floor. (B) is a flowchart in a case where a schedule is entered when a decrease in service due to passage of a full load is detected. The full departure is detected (b2), and the main destination floor at that time is checked. Next, it is checked whether or not a call has occurred immediately after the departure of the service elevator on the floor where the full load has occurred (b3).
If it has not occurred, normal operation is performed, and if it has occurred, direct operation is performed between the full-occurrence floor and the main destination floor (b4),
Further, it is checked whether or not a call has been generated on the packed floor for a predetermined time, and if a call has been generated, the steps after (b4) are repeated, and if no call has been generated, the operation returns to the normal operation.
(C) is an example in which the scheduled operation is performed based on the number of people getting on and off and the time zone. First, it is detected that the set time zone has come (c1). Next, it is detected whether or not a large amount of entry has occurred on the planned floor (c2), and if there is no large amount of entry, it is determined that the planned traffic demand has not occurred and normal operation is performed. If there is a large amount of boarding, the main destination floor is detected (c3), and direct driving is performed between the specific floor and the main destination floor (c4). Next, it is checked whether or not the demand of the specific floor has disappeared (c5). If the demand has not disappeared, the process is repeated from (c4). If the demand has disappeared, the operation returns to the normal operation. (D) is an example in which a scheduled operation is performed when a waiting sensor that detects the number of waiting customers at the landing detects a large number of waiting customers. First, the waiting sensor detects high demand (d1). Next, the main destination floor is detected (d
2) Investigate whether a call has been registered immediately after departure before or after a packed floor or a high demand floor (d3). If no call has been registered, normal operation is performed. Direct operation is performed between floors (d4). Further, it is checked whether or not the demand for high demand has disappeared (d5). If the demand has not disappeared, the steps after (d4) are repeated, and if there is no demand, the operation returns to the normal operation. According to the present embodiment, the high demand can be accurately detected by the waiting sensor. The reason for (e) is that when a hall call arrives, nobody gets on and a hall call occurs immediately and a scheduled operation is performed. This is an example of the case. First, it is detected that the passenger has arrived at the hall call in a state close to being full and there was no getting on / off (e1). Then, it was checked whether or not the hall call was registered immediately after leaving the hall call generating floor (e2). If not, normal operation is performed, and if registered, the vehicle goes straight to the floor after the end service (e3). Next, a service for the hall call generated on the floor is performed (e4), and it is checked whether a call has been generated on the floor for a certain period after the elevator departure (e5). (E3) The following is repeated, and if no error occurs, the operation returns to the normal operation. According to the present embodiment, it is possible to improve the service of the floor where the service car has arrived in the congested state. (F) An example of providing the direct service to the floor where the service has decreased. First, it is detected that a service-degraded floor has occurred due to the passage of a full load or the like (f1). Next, it is checked whether or not there is a call on the service lowering floor (f2). If there is no call, normal operation is performed. If there is a call, the terminal goes straight to the service lowering floor after the end floor service (f2).
3), the floor is serviced (f4), and it is checked whether or not a call is generated in the floor (the driving direction is determined by the state of the floor) during a certain period after the elevator departure (f5). ), If a hall call has occurred (f3), the following steps are repeated, and if no hall call has occurred, the operation returns to the normal operation.

FIG. 25 shows an embodiment which can be operated by a waiting person. If the floor of an office building where high demand has occurred is a conference room or the like, the destination can not be determined in advance, but it is almost always decided. In such a case, as shown in (a), the destination is provided with destination buttons 141 to 14n integrated with the display at the landing, or until a car call occurs without deciding the destination direction of the schedule operation elevator which becomes an express. Good service can be provided even when the destination is not fixed in a time zone or the like by operating the portable terminal. Conventionally, the vehicle only arrives at the floor, and in the present invention, the vehicle goes straight to the car floor after coming to the hall call floor. (B) is an embodiment in which the user can select a desired floor when he / she wants to go to a floor other than the floor on which the scheduled operation is performed. Instead of using such a button, a normal operation assigned car other than the scheduled operation can be selected by pressing a hall call button other than near the elevator reserved for the scheduled operation. If there is only one set of hall call buttons on each floor, such as when one or two elevators are installed, whether the hall call button was pressed again after the scheduled operation reservation, whether it was pressed twice, etc. The registration of the normal driving car may be performed.
(C) and (d) are examples in which a destination is registered as express operation using an indicator and a hall call button. For example, by pressing the up / down call button for a certain period of time, the express operation is registered, and after the registered and express display is performed, the destination floor is set using the up / down call button. The destination floor to be set is displayed in a blinking manner. When the upward button is pressed, the number of floors increases, and when the downward button is pressed, the number of floors decreases. Next, it is detected that the same floor is set on the same floor for a certain period of time, and that floor is set as the destination floor. As above
