Description

The present invention relates to an elevator system that increases the number of people transported by an elevator, and more particularly to an elevator system that aims to increase the number of people transported per hour during congestion such as when going to work.

The elevator system transports a large number of users smoothly and safely every day as a means of vertical transportation in the building. Especially in a large building, since the number of users is large, multiple elevators are installed, and the group management system manages these multiple elevators as one group.

The purpose of such an elevator system is to transport as many users as possible to the destination floor per predetermined time, which is especially important during busy times such as when going to work or at lunch. The number of people transported per predetermined time is used as an index showing the transportation capacity of the elevator system.

As a technology to improve the transportation capacity against the up-peak traffic flow at the time of going to work or the latter half of lunch, the elevators managed by multiple groups are divided into multiple groups, and the floor of the destination floor of each group's elevator is divided into zones. An operation method called split express control or zoning control is applied. As an example of dividing the zone, there is an example of dividing into two zones, a high-rise zone and a low-rise zone.

In such split express control or zoning control, for high concentration demand between specific floors, the number of express elevators that exclusively service the specific floor demand is determined, and as a control for operating each elevator, for example, a patent. Document 1 is known. According to Patent Document 1, the number of passengers getting on and off each floor is estimated by the load sensor in the car, and the traffic demand in the building is estimated based on the estimation.

In addition, an example of destination floor reservation type (Destination Control) elevator group management that obtains destination floor information (call of the destination floor) and assigns an elevator to be serviced to that destination floor is known, and in particular, the user is at the elevator platform. For example, Patent Document 2 describes an example of control in which a destination floor is detected from the user's ID information (individual authentication information) before arrival and an elevator unit to be serviced is assigned to the destination floor. ..

Japanese Unexamined Patent Publication No. 9-20247 JP-A-2015-21803

The estimation by the load sensor in the car adopted in Patent Document 1 is only the estimation after the passenger gets into the car. Therefore, there is a deviation (error in the number of passengers, delay in detection time) with respect to the number of passengers actually at the landing. Especially when a large number of users are waiting at the platform due to busy work hours and they are lining up without getting on the elevator that arrived, it takes time to finish carrying all of them, so the total number of people is accurate. It can be difficult to estimate. For this reason, there is a possibility that there is an error in the demand between specific floors assumed by the control side, and the number of elevators and floors to be serviced there are not appropriate.

Patent Document 2 is premised on destination floor reservation type group management. For this reason, it may be difficult to carry out the usual elevator group management of up / down button type landing calls. For example, if such a control method is to be implemented later for the elevator group management of the up / down button type landing call, a large-scale modification is required for both the equipment and the control.

Furthermore, it is necessary for the user to always attach the ID information, and it is necessary for the control side to be able to detect it. It may be troublesome for the user to attach the ID information, and it may be difficult for the control side to remotely detect it by wireless or the like (power to output the wireless is required on the device side of the ID information). It is difficult to secure that much power capacity, etc.). If the ID information is not obtained accurately, it will result in a detection error of the number of people, which may lead to a decrease in transportation capacity.

From the above, it is an object of the present invention to improve the number of people to be transported by elevators at the time of work or at the time of congestion such as the latter half of lunch by a simpler and more accurate method while based on the usual elevator group management of up / down button type landing calls. The purpose is to provide an elevator system that can be planned.

In order to achieve the above object, the present invention is "an elevator system for split express control of a plurality of elevators in a building building, which is provided at a building entrance and is provided for each of a plurality of groups on the destination floor of the split express control. A building number detection system that detects the number of buildings, a control specification determination system that determines the control specifications for split express control according to the number of buildings in each group detected by the building number detection system, and a division defined by the control specification determination system. The elevator system is characterized by being equipped with an elevator group management system that divides and controls a plurality of elevators in the building according to the control specifications of the express control.

According to the present invention, the number of people in each destination floor group of building users can be directly detected by a simpler method based on the usual elevator group management of up / down button type landing calls.

Further, according to the embodiment of the present invention, it is possible to efficiently control the operation of elevators divided into a plurality of groups according to the destination floor based on a more accurate number of people, and when the elevator is crowded such as when going to work or in the latter half of lunch. It is possible to improve the number of people who can transport elevators.

Hereinafter, examples of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a diagram showing an overall configuration example of an elevator system according to an embodiment of the present invention.

The elevator system according to the embodiment of the present invention is a control for determining the control specifications of the elevator group management system 3 for controlling the elevator group 2 installed in the building 1 and the split express (or zoning method). The specification determination system 8 and the building number detection system 7 installed in the building entrance 4 to detect the number of people entering the building 1 and the building number detection system 7 installed in the elevator hall of the building building 1 are divided express (or It is composed of an information display device 9 that displays information of the zoning method).

In the following description of the present invention, the split express will be described as a concept including zoning. Further, the division express means so-called service floor division operation / control or zone division operation / control.

In the example of FIG. 1, an elevator group 3 composed of a plurality of elevators (5 in the example of the figure) is installed in the building 1, and transports users who move vertically in the building. The elevator group management system 3 manages the elevator group 3 as one group.

The elevator group management system 3 efficiently controls a plurality of elevator groups 2 according to the usage status of each floor in the building building 1, increases the number of people transported per hour (hereinafter referred to as transportation capacity), and also allows users. We are trying to reduce the waiting time of the elevator at the platform.

In particular, high transportation capacity is required during up-peak hours (up-peak hours of use) such as when going to work or in the latter half of lunch. Here, since many users move from the lobby floor (or the dining room floor) to the upper floors all at once by using the elevator, it is necessary to increase the transportation capacity according to the number of users.

Here, the problem at the time of up-peak is the increase of one lap time of the elevator (hereinafter, simply referred to as one lap time). Since passengers boarding on the lobby floor register a large number of destination floor calls (car calls) in the car, each elevator is in a state of stopping almost on each floor, the one lap time increases, and the number of people transported per hour, that is, The transportation capacity will be reduced. As a result, there are cases where users cannot be transported smoothly and queues occur on the lobby floor.

An effective driving method to improve this is called the split express method. For example, the elevator group 2 is divided into two groups, and one group is divided into two groups (for example, the service floor in the lower half) (for example, only during work hours). Divide the other group into the upper half of the service floors (for example, 9th to 15th floors) to reduce the number of stops on the destination floor and shorten the lap time. Improve transportation capacity. The elevator system according to the embodiment of the present invention is based on this split express, and aims to further improve the transportation capacity by more appropriate mechanism and control.

Returning to FIG. 1, this figure is a situation assuming the time of going to work, and shows a situation in which a large number of users are accessing toward the building entrance (building entrance) 4.

In the present invention, a building number detection system 7 for grasping the number of building people to enter is arranged at the building entrance 4. The number of buildings grasped here is not the total number of people, but the number of buildings for each service floor by the split express method. For this purpose, the passage 5 from the outside of the building to the building entrance 4 is divided into two passages 5a and 5b determined for each destination floor by the split express method, and the number of people passing through each of the divided passages 5a and 5b is determined. I know.

Specifically, the passages 5a and 5b are divided into two areas, group A defined by the display 6a on the destination floors on the 2nd to 8th floors and group B defined by the display 6b on the destination floors on the 9th to 15th floors. Are divided, and the user is consciously guided to pass through the areas (traffic areas) of the passages 5a and 5b according to the respective destination floors. This number of people is detected by the number of people detection device (group A is the number of people detection device 7a, group B is the number of people detection device 7b) for each group. As a result, the number of people in each destination floor group can be obtained in real time with an accurate value before arriving at the elevator platform. Here, the number detection devices 7a and 7b include, for example, a number detection sensor using a laser sensor, an optical sensor, an infrared sensor, an image sensor (camera), a line sensor, or the like that rotates to scan the surrounding area. Can be mentioned.

As described above, the building number detection system 7 is formed by the passages 5a and 5b with the indications 6a and 6b on the destination floor and the number detection devices 7a and 7b. As will be described later, the number of people detection devices 7a and 7b may be permanently installed at the building entrance 4, but may be temporarily installed at a time when the admission trend is desired to be grasped.

The control determination system 8 of the split express is the number of people in each destination floor group obtained from the number detection devices 7a and 7b, and the correspondence information between the number detection devices 7a and 7b and the destination floor (for example, the destination in the number detection device 7a). (Information that the 2nd to 8th floors of the floor group correspond), the time information at the time of detecting the number of people and the calendar information are used as input information, and the control specifications of the split express are determined based on these input information. This control specification includes, for example, the setting of the floor zone serviced by each elevator group of the split express, the setting of the elevator unit belonging to each elevator group, the time schedule of these, and the like. Specific examples of this control specification are shown in FIGS. 4a and 4b, which will be described later.

In this split express control determination system 8, the control specifications of the split express are determined according to the number of people in each destination floor group, and more appropriate split express operation is carried out according to the usage status of the building when going to work. It will be.

For example, in the first half of work hours (for example, 8: 00-8: 30), the number of people in group B (9th to 15th floors) on the destination floor is large, so the number of elevators on the split express is larger in group B (for example). For example, group A has 2 units, group B has 3 units), and conversely, in the latter half of work hours (for example, 8: 30-9: 00), the number of destination floor group A (2nd to 8th floors) is large. It is possible to execute control such that the number of elevators of the split express is distributed more to Group A (for example, Group A has 3 units and Group B has 2 units). As a result, it is possible to secure a transportation capacity that matches the usage situation and improve the overall transportation capacity.

Appropriate control specification data determined by the split express control determination system 8 is transmitted to the elevator group management system 3, and the elevator group management system 3 executes the split express operation according to the control specifications.

Similarly, this control specification data is also sent to the information display device 9 of the split express to display and guide the elevator user with the execution information (time zone, elevator unit, destination floor, split group) of the split express.

The user sees this displayed information and gets on the appropriate elevator group unit according to the destination floor. The information displayed by the information display device 9 is, for example, information as shown in FIGS. 4a and 4b, which will be described later. In addition, the information display device 9 should be installed in a location that is easily visible to elevator users on the lobby floor, such as inside the elevator platform, at the platform entrance, near the platform, and inside the building entrance. May be done.

Here, the division express control determination system 8 of FIG. 1 is described as being outside the building building 1, but for example, a server outside the building connected by a communication network (for example, a service of a building or an elevator). A server managed and operated by a business operator) is assumed. This server may be a server inside the building 1 (for example, a server operated for this building), or may be implemented as a function in the elevator group management system 3.

As described above, the elevator system shown in FIG. 1 can divide users into a plurality of groups determined by the destination floor and accurately detect the number of each group. Based on the number information for each group, the appropriate elevator group and service floor can be detected. A split express consisting of floors can be carried out. As a result, it is possible to improve the transportation capacity of the elevator when going to work or in the latter half of lunch.

Furthermore, the mechanism for dividing this user into multiple groups determined by the destination floor (divided by the traffic area) and detecting the number of each is a simple mechanism, which is a group management elevator with a normal up / down button type landing call. It can be easily installed and connected by external / retrofitting. For this reason, as an optional form of retrofitting to the group management elevator, it is possible to install it later in the case of a heavily congested building.

Furthermore, if necessary, the number of people detection devices 7a and 7b, the display 6a and 6b of the destination floor, and the area division 5a and 5b of the passage are installed for a certain period of time, and the number of people for each group on each destination floor is detected and used. It is also effective to determine and operate the control specifications of the split express based on this, and then remove the number detection device. For example, for a while after the building opens and the tenant enters the building, the number of people for each destination floor group at the time of going to work is detected, and based on that, the control specifications for the split express are determined and operated. After that, when the tenant changes or the number of people changes significantly, the above-mentioned number detection mechanism is installed again to detect the number of people, and based on that, the control specifications of the split express are adjusted and operated. .. Such an operation is also practically effective. In the case of such an operation mode, it is considered that the period for detecting the number of people should be a period of 1 to 6 months (3 months on average) in order to know the macro tendency of the number of people at work. Because it can fluctuate by day of the week (for example, a tenant on a certain floor has a big meeting on Monday and a lot of people gather in the building), and it can fluctuate weekly (such as a big meeting or event in the second week). In order to average this, we think that a period of at least one month for detecting the number of people is necessary.

As described above, the number detection devices 7a and 7b are not installed for a limited time, but are always installed, and the floors and elevators of each zone of the express are divided in real time according to the number of people in each group on the detected destination floor. You may implement the control to change. Since the number of users entering the building for each destination floor group is known in advance, it is possible to control the building according to the usage status by dividing the express control accordingly.

FIG. 2 is a block diagram showing the function of the elevator system of FIG. This corresponds to the processing related to the control function in the elevator system shown in FIG. In FIG. 2, the processes corresponding to FIG. 1 are designated by the same reference numerals. Hereinafter, FIG. 2 will be described.

The building number detection system 7 of FIG. 1 is composed of number detection devices 7a and 7b, destination floor group displays 6a and 6b, and passages (traffic areas) 5a and 5b for each destination floor group. The functions achieved by these can be displayed as functional blocks B71, B72, and B73 as shown in FIG.

According to the block notation of FIG. 2, specifically, the destination floor information setting unit B71 (corresponding to the display 6a and 6b of the destination floor group in FIG. 1) sets the destination floor information of each destination floor group, and further, the clock B72. The time when the number of people was detected is recorded. The number detection unit B73 for each destination floor detects the number of users divided into groups on the destination floor in combination with the set destination floor information (detected by the number detection devices 7a and 7b in FIG. 1). It is necessary to link the destination floor information and the time to the number data detected by the number detection devices 7a and 7b, and the information is transmitted from the destination floor information setting unit B71 and the clock B72 to the number detection unit B73 for each destination floor. The three parties are associated with.

Thus, the data given to the control specification determination system 8 of the split express by the building number detection system 7 is, for example, the number of users in the passages (traffic areas) 5a and 5b for each destination floor group measured at 5-minute intervals. This number is sequentially given to the control specification determination system 8 at 5-minute intervals.

The function of the split express control specification determination system 8 of FIG. 1 can be displayed as functional blocks B81 to B88 as shown in FIG. 2, and the control specification of the split express is determined by this process. The details are as follows.

The time data at 5-minute intervals given by the building number detection system 7 and the number detection data for each destination floor are sequentially accumulated in the number data storage unit B81 for each time and destination floor. The number of people data for each time and destination floor has the data structure shown in FIG. Since these data are collected in large quantities over a period of one month or longer, they are stored in the number database B82 by time and destination floor.

According to FIG. 3 showing the storage structure of the number of people database B82 by time and destination floor, the horizontal axis of this database is, for example, the time zone D02 at 5-minute intervals and the destination floor group A (2nd to 8th floors) D03. , Destination floor group B (9th to 15th floors) D04. In addition, this data is collected and stored together with the data D01 of the collected date and time, for example, data for a period of one month or more.

Next, the control specification change determination unit B83 of the split express determines whether or not the control specification of the split express currently being implemented should be changed. Basically, the change in the current number of people data is small compared to the number of people data by time and destination floor (obtained from the number database B82 by time and destination floor) when the control specifications currently being implemented are set. If so, continue the current specifications. If the change in the number of people is large, the current control specifications may not be suitable, and it is decided to change the specifications.

Explaining according to FIG. 3 showing an example described in the number database B82 by time and destination floor, for example, it is shown by D05 between 8:00 am and 8:30 am on Friday, October 15, 2019. During the period, the number of people in destination floor group B (9th to 15th floors) D04 is larger than the number of people in destination floor group A (2nd to 8th floors) D03, while it is from 8:30 am to 9:00 am. During the period indicated by D06 between minutes, the number of people in destination floor group B (9th to 15th floors) D04 is smaller than the number of people in destination floor group A (2nd to 8th floors) D03.

Therefore, the ratio of the number of destination floor groups A and B during the time zone 08: 25-08: 30 in FIG. 3 and the number of destination floor groups A and B during the time zone 08: 30-08: 35. By comparing the ratios, it can be judged that the current control specifications are not suitable.

Here, when the number of people detection devices 7a and 7b are permanently installed, the current number of people detection data can be used as they are from the number of people detection devices 7a and 7b. If the number of people detection devices 7a and 7b are not permanently installed and have already been removed, the number of people by time and destination floor estimated by the elevator group management side based on the load sensor of the car may be used for comparison. .. In the case where the number detection devices 7a and 7b are not always installed, if it is determined that the control specifications have changed, it is better to re-install the set of the number detection devices 7a and 7b and redetermine the control specifications. ..

In addition to judging the specification change based on the detected change in the number of people, use the current number of people detection value or the estimated number of people (car load sensor) and compare it with the transport capacity under the current control specifications of the split express. Then, you may judge whether the current specifications are appropriate. In this case, the current split express control specification is acquired from the split express control specification data storage unit B84.

When it is determined that the control specifications need to be changed (including the case where the split express is newly implemented when the split express has not been implemented so far), the control specification selection unit B85 of the split express is a candidate for the control specifications. To select.

In addition, since there are variations in work hours and lunch times on each floor during actual work and lunch in the building, the peak number of people in each destination floor group as shown in FIG. 3 is often biased. This is detected by the building number detection system (the number detection devices 7a and 7b in FIG. 1, the display 6a and 6b of the destination floor group, and the set of the passages 5a and 5b divided by the area of the destination floor group) with an accurate and simple mechanism. It is possible to do. It is also possible to measure by retrofitting or temporary installation.

4a and 4b show examples of control specifications stored in the control specification data storage unit B84 of the split express. Of these, FIG. 4a is a diagram showing an example of initial setting (at the start of operation) of control specifications. Further, FIG. 4b is a diagram showing an example of setting after changing the control specifications (adjusted according to the usage situation after operation). In these tables, the time zone D02, the control specification D07, the destination floor group A (D03), and the destination floor group B (D04) are described on the horizontal axis, and the time zones D05 and D06 are described on the vertical axis side. .. According to this example, as the control specification D07, control specifications are set from the two viewpoints of (1. Elevator unit) and (2. Destination floor). Therefore, the candidates for control specifications are (1. Elevator unit) and (2. Destination floor), and one or both of these are changed so that the transportation volume is appropriately adjusted according to the state at that time. become. Which control specification should be changed should be appropriately determined according to the operating conditions at that time.

First, an example of the control specification of the split express at the start of operation of FIG. 4a will be described. The data table shown in FIG. 4a represents the control specifications. In this example, the implementation time zone (D05, D06), each elevator group (D03, D04) of the split express, the name of the elevator unit to which the elevator belongs, and each data of the destination floor of the elevator of the group are stored. Specifically, during the implementation time zone of code D05, the elevators belonging to the destination floor group A (D03) are Units 1, 2 and 3, and the destination floor is the 2-9 floor. The elevators belonging to the destination floor group B (D04) are Units 4 and 5, and the destination floors are the 10th to 15th floors. In this way, the split express operation divides the destination floor (service floor) into zones (areas) and distributes the elevators that service each floor.

FIG. 4b shows after a certain period of time has passed since the start of operation (for example, 3 months have passed), data on the usage status of the building (data for detecting the number of people by destination floor group) has been accumulated, and the control specifications have been adjusted. An example of specification data is shown.

Focusing on the difference from FIG. 4a, first, in the time zone D05 from 8:00 to 8:30, the destination floor group A (2. destination floor) and the destination floor group B (2. destination floor) Is changed in FIGS. 4a and 4b. Group A has a decreasing number of destination floors and Group B has an increasing number. This is because the number of people in Group A is large after operation, and it is necessary to increase the transportation capacity of Group A, and the number of destination floors has been moved from Group A to Group B.

Further, in the time zone D06 from 8:30 to 9:00, the number of destination floor group A (1. Elevator unit) decreased from 3 to 2 in comparison with FIGS. 4a and 4b. The number of destination floor group B has increased from two to three. This is because, on the contrary, it is necessary to greatly increase the transportation capacity of Group B during this time, and one unit (Unit 3) was moved from Group A to B.

Due to the difference in the work hours of tenants on each floor, the number of people in the destination floor group often changes depending on the time zone, and as shown in Fig. 4b, the control specifications for the divided express (for example, the number of elevators are distributed). Etc.) is effective. The reason why such adaptive control is possible is that the number of people can be accurately grasped by detecting the number of people for each destination floor group described in FIG. 1 and that the number of people can be grasped in advance before entering the building.

Returning to FIG. 2, the control specification evaluation unit B86 of the split express calculates the transport capacity by the transport capacity calculation unit B87 by traffic calculation for the selected split express control specification, and this transport capacity value and the current time of detection are calculated. Compare with the number of people data by different / destination floor. If the transportation capacity (transportation number) is appropriate for the number of people, the control specifications may be used. If not, return to the control specification selection unit B85 of the split express, change the control specifications, compare the transportation capacity and the number of people data again in the evaluation unit B86, and repeat this process until the appropriate control specifications are determined. ..

The appropriate control specifications determined through such processing are output to the elevator group management side by the control specification output unit B88 of the split express. At the same time, this specification data is also stored in the control specification data storage unit B84.

The functions achieved by the elevator group management system of FIG. 1 can be displayed as functional blocks B31, B32, and B73 as shown in FIG.

In the elevator group management system 3, the split express operation is carried out according to the determined appropriate split express control specifications. Specifically, based on the time information of the clock 31, the control execution unit 32 of the split express executes the split express operation according to the control specifications in accordance with the execution time defined in the control specifications of the split express. At the same time, the driving information for the user is displayed and guided to the driving information display unit 9 of the split express.

In this way, based on the number of people detection data for each destination floor group, the control specifications of the split express suitable for it are determined and executed in the actual elevator group management. Furthermore, the control specifications of the split express are reviewed as appropriate according to changes in the number of passengers. As a result, it is possible to increase the number of people transported by the elevator when the elevator is busy, such as when going to work or in the latter half of lunch, with more accurate and suitable control.

The information on the control specifications of the split express shown in FIGS. 4a and 4b is displayed and guided to the elevator user by the information display device 9 of the split express shown in FIG. As a result, the user can also see this information and use the elevator appropriately.

As described above, the control specifications are the specification data as shown in FIGS. 4a and 4b, and are composed of the data of the implementation time zone, the unit belonging to the elevator group, and the service floor zone of each group. Basically, the control specifications of the current split express are selected as initial (default) candidates. Alternatively, the data of the past control specifications may be acquired from the control specification data storage unit B84 of the split express.

FIG. 5 is a flowchart showing an adjustment process of control specifications for a split express train related to an elevator system according to an embodiment of the present invention. This is a process executed by the control specification determination system 8 of the split express of FIGS. 1 and 2, the control specification selection unit B85 of the split express of FIG. 2, and the control specification evaluation unit B86 of the split express of FIG. This process is a specification adjustment process when the number of detected users changes and it becomes necessary to change (review) the control specifications of the split express. Hereinafter, this flowchart will be described.

In the first processing step S101 of the flowchart of FIG. 5, a time zone (for example, 30 minutes) at the time of up-congestion during which the split express operation is performed is selected. Next, in the processing step S102, the number of people data by time and destination floor in this time zone is extracted. Then, in the processing step S103, the transport capacity in the normal operation method other than the split express operation is compared with the total number of users in the time zone (the average value seen in a certain period is used), and the transport capacity is compared. If it is larger, the process proceeds to process step S104, and normal operation other than split express is performed.

If the transport capacity is smaller (insufficient transport capacity), the process proceeds to step S105, and it is determined whether or not the split express operation has already been performed. If this is the case, the next step is processing step S106, in which the transportation capacity of the current split express is compared with the total number of passengers (average value) in the time zone. If the transport capacity of the current split express is larger, the current split express is continued as it is in the processing step S107.

If the transportation capacity is small (insufficient transportation capacity), the control specifications of the current split express may not be appropriate, and the control specifications will be adjusted. This is the process from the process step S108 to the process step S114. In the example of FIG. 5, it is assumed that there are two divided zones (divided zones A and B), but when the transport capacity is small, one of the two divided zones has insufficient transport capacity and the other has transport capacity. Is presumed to be satisfied. Therefore, the control specifications are changed so as to increase the transport capacity of the zone on the side where the transport capacity is insufficient and decrease the transport capacity of the other zone. For example, adjustments will be made to move one elevator in charge from the zone where the transportation capacity is sufficient to the zone where the transportation capacity is insufficient. Hereinafter, a specific description will be given.

First, in the processing step S108, it is determined whether the divided zone A has insufficient transport capacity and the divided zone B has sufficient transport capacity. In the case of Yes, in the processing step S109, the control specifications are adjusted so that the service floor of the division zone A is moved to the division zone B or the elevator unit in charge of the division zone B is moved to the division zone A charge. If No, in the processing step S110, it is determined whether the divided zone B has insufficient transport capacity and the divided zone A has sufficient transport capacity. Again, if No, the transportation capacity is insufficient in both zones, so it is necessary for a professional engineer to take action in processing step S111, and the system will contact the service provider. In the case of Yes, in the processing step S112, the control specifications are adjusted so that the service floor of the division zone B is moved to the division zone A or the elevator unit in charge of the division zone A is moved to the division zone B charge.

With respect to the control specifications of the new split express obtained by the above adjustment, the transport capacity is calculated again in the processing step S113, and in the processing step S114, the transport capacity of the new split express and the time zone are changed. Compare with the total number of users (average value). If the transport capacity is large (satisfied), the new control specification is appropriate, and if the transport capacity is small (insufficient), the process returns to process step S108 and the control specifications are adjusted again.

When the transport capacity of the new control specification is satisfied, in the processing step S115, it is finally determined whether or not the condition for changing the control specification of the split express is satisfied. The change condition is, for example, whether a predetermined period has passed since the last change (for example, 3 months have passed), or whether there has been a case where the control specification did not work in the past. When this condition is satisfied, the control specification of the split express is changed in the processing step S115.

As described above, by the adjustment process of the control specifications shown in FIG. 5, the control specifications can be adjusted according to the change in the number of people for each actual destination floor group detected by the number detection devices 7a and 7b, and an appropriate transportation capacity can be maintained. .. Here, the change in the number of people is caused by the change of tenants, the change of the number of people due to the organizational change in the tenant, the change of work hours and lunch time, and the like.

FIG. 6 is a flowchart for a change determination process of the control specification of the split express related to the elevator system according to the embodiment of the present invention. This shows the processing performed by the control specification change determination unit B83 of the split express in FIG. This is to judge the change of the control specification when the tendency of the number of people by destination floor changes due to the replacement of tenants or the change of work hours, and if it is not suitable for the current control specifications. This flowchart will be described below. In FIG. 6, it is assumed that the number of people detection device is not always installed, but is installed and detected as needed. Therefore, it is removed when it is not needed.

In the flow of FIG. 6, first, in the processing step S201, the estimated value of the number of passengers getting on and off for each stop floor is calculated from the load in the car of the elevator or the detection data of the camera in the car. Next, in the processing step S202, the estimated value of the number of people by time and by destination floor is calculated from the estimated value of the number of passengers getting on and off. The processing up to this point is carried out by the elevator group management system 3. In the following, this value will be referred to as the estimated value of the number of people by time and destination floor by group management.

Then, in the processing step S203, it is determined whether or not a predetermined period has elapsed from the previous control specification setting (including the case where there is no change), whether it is a specific month, or whether there is a change determination request command. Here, the predetermined period is a period of change in the number of people, and considering the change of tenants, it is considered that about 3 months is good. Also, as a specific month, I think that April or October, when there is a change in the organization, is good. The change determination request command corresponds to, for example, a request from the building manager.

If the determination process in the process step S203 is Yes, then in the process step S204, it is determined whether or not the split express operation has already been performed.

When the split express operation is being carried out, the number of people data by time and destination floor used when determining the control specifications of the current split express in the processing step S205 is acquired. Then, the estimated value of the number of people by time and destination floor obtained by group management obtained in processing step S202 and the number of people by time and destination floor used when determining the control specifications of the current division express obtained in processing step S205. The data are compared in the processing step S206, and it is determined whether or not the difference between the two is equal to or greater than a predetermined value. If the difference between the two is greater than or equal to the specified value, there is a possibility that the number of people has changed from the current control specifications.

When it is determined in the process of the process step S204 that the split express operation is not performed, the necessity of the split express is calculated from the estimated value of the number of people by time and destination floor by the group management in the process step S207. This necessity calculation is judged by comparing with the transportation capacity by traffic calculation. From this result, it is determined in the processing step S208 whether or not there is a need for a split express (currently, the transportation capacity is insufficient).

When the difference between the two is greater than or equal to a predetermined value in the determination process of the process step S206, or when the determination process of the process step S208 determines that the division express is necessary, the number detection device for each destination floor is used in the process step S208. We will measure the number of people by hour and by destination floor. This is carried out by re-installing a set such as a number detection device and a display of the destination floor group. As already mentioned, this measurement period is preferably at least one month.

As a result of the above, when the number of people data for each hour and each destination floor is collected, the control specification of the split express is set based on the data in the processing step S210.

With the above method, even if the number of people detection device is not always installed, the change in the number of people can be detected by using the data on the elevator group management side, and the number of people detection device can be installed and measured as needed. .. In the case of such a form, the building manager can use the device as needed without purchasing the device, and the introduction cost can be reduced.

7a and 7b show the building number detection system of the elevator system according to the embodiment (number detection devices 7a and 7b in FIG. 1, display 6a and 6b of the destination floor group, passage 5a divided by the area of the destination floor group, It is a figure which shows the arrangement state of 5b).

FIG. 7a shows an example of setting the control specification of the split express offline, and FIG. 7b shows an example of setting the control specification of the split express online in real time based on the number of people detection data. Those common to FIG. 1 are designated by the same reference numerals.

First, FIG. 7a shows a case where the control specification of the split express is set offline, and this is a case where the number detection data is accumulated for a certain period and the control specification of the split express is set based on the data. For example, it is a case where the detection data is accumulated for three months, the control specification of the split express is calculated and determined based on the detection data, and the split express operation is performed according to the control specification from a certain time.

In this case, it is not necessary to immediately reflect the detected number of people data in the control specifications, and the detection can be performed independently. Therefore, the building number detection system (number detection devices 7a, 7b in FIG. 7a, destination floor group display 6a, 6b, a set of passages 5a and 5b divided by the area of the destination floor group) may be installed closer to the elevator group 2.

FIG. 7a shows an example in which the distance 12 between the number of people detection devices 7a and 7b (these detection areas are represented by the dotted line areas 10) and the elevator platform 11 is arranged within 10 to 30 m. From the viewpoint of installing the number of people detection devices 7a and 7b, it is easier to install them at a position closer to the building, so in this offline case, it is better to install them at a closer position. Further, in such an offline setting, the positions of the number of people detection devices 7a and 7b do not necessarily have to be outside the building, but may be inside the building entrance 4. However, it is necessary to secure a certain distance from the elevator platform in order to have the users act so that they are divided according to the destination floor.

Next, FIG. 7b shows a case where the control specification of the split express is set online, and this is a case where the control specification of the split express is set by using the number detection data in real time.

In this case, it is desirable to detect the number of people as soon as possible because it takes time from the detection of the number of people to the setting of the control specifications of the split express and the execution of the control. Therefore, FIG. 7b shows an example in which the distance 12 between the number detection devices 7a and 7b (these detection areas are represented by the dotted line areas 10) and the elevator platform 11 is arranged at 30 to 100 m or more. .. This is because it is considered that one lap time (1 to 2 minutes or more) of the elevator is required from the detection of the number of people to the arrival at the elevator platform.

Even in this online case, it is not preferable to frequently change the control specifications of the split express in a short time (because the user is confused), and the basic is as short as 30 minutes as shown in FIGS. 4a and 4b. I think it is appropriate to switch in about 15 minutes. In this case, the reason for performing the number detection online is that the occurrence of congestion can be detected quickly. For example, since the time of occurrence of congestion changes depending on the operating status of trains and buses, signals, etc., it is considered that this can be detected promptly.

8a, 8b, and 8c are diagrams showing an installation example of the number of people detection device for each destination floor group. The same ones as in FIG. 1 have the same reference numerals.

FIG. 8a shows a mode in which the number detection devices 7a and 7b are installed at both ends of the aisle, and the 7a and 7b detect the number of users passing through the aisles 5a and 5b of the two destination floor groups, respectively. In this case, the number detection devices 7a and 7b are suitable for laser sensors that rotate to scan the surrounding area. In addition, an image sensor (camera) or an infrared sensor may be used.

FIG. 8b shows a mode in which the number of people detection devices 7c, 7d, and 7e are installed at both ends and in the middle of the passage to detect the number of people. In this case, the number of people passing through the passage area 5a (destination floor group on the 2nd to 8th floors) on the line 7c1 of the number detection devices 7c and 7d, and the passage area 5b (9th to 15th floors) on the line 7e1 of the number detection devices 7d and 7e. The number of people passing through the destination floor group) is detected. In this case, a line sensor, an image sensor (camera), an infrared sensor, a laser sensor and the like are suitable.

FIG. 8c shows a mode in which the number of people detection devices 7f and 7g are installed in the upper part of the aisle and the number of people passing through the aisle area in charge of each is detected. In this case, the number detection device places a structure such as reference numeral 7h and detects from the structure. In this case, since the number of people is detected from above, it is easy to obtain the field of view of the sensor, and an image sensor (camera) or an infrared sensor is suitable.

9a and 9b are diagrams showing an example of display means for dividing the passage into the area of the destination floor group. In particular, in the form of this example, the group of the destination floor to be displayed can be changed. In FIG. 9, the same ones as those in FIG. 1 have the same reference numerals. FIG. 9a shows before the display is changed, and FIG. 9b shows after the display is changed.

According to FIG. 9a, display means 6c and 6d for dividing the passage into the area of the destination floor group are provided, respectively, and each displays the destination floor group. For example, the display means 6c outputs the display 6a of the destination floor groups 2 to 8, and the display means 6d outputs the display 6b of the destination floor groups 9 to 15. This display output is, for example, a projection by a projector device or a display screen (liquid crystal, etc.).

FIG. 9b shows a case where the destination floor group is subsequently changed and displayed, the display means 6c is changed to the display 6a of the destination floor groups 2 to 6, and the display means 6d is the destination floor groups 7 to 15 floors. The display is changed to 6b. For example, if the number of people on the 2nd to 8th floors of the destination floor group is larger than initially expected, reduce the floors of the destination floor group to 2nd to 6th floors, detect the number of people, and balance the number of people with the other group. It becomes possible to evaluate whether or not it can be taken.

By making the display of the destination floor group variable in this way, the constituent floors of each destination floor group can be flexibly changed, and even in that case, the number of people in each group can be accurately detected.
