Description

Embodiments of the present invention relate to an elevator group management control device.

The group management control device that controls the elevators of multiple units in general, based on the assigned evaluation value for each unit calculated based on the length of the hall waiting time, etc. The assigned machines to be assigned have been decided. However, for example, if the user who operated the hall call is a woman and only the male user is in the car of the assigned car that arrived at the hall in response to this hall call, In some cases, the user does not board the car in order to avoid carpooling with the user in the car, and as a result, the service efficiency of the elevator may be reduced.

In the operation control of a single elevator, for example, there is a technology to prevent carpooling by restricting boarding into the car to only one user and driving the car directly to the destination floor of the boarding user. Are known. However, since group-controlled elevators are installed in an environment with many users, there is a concern that if such operation control is directly applied to group management control, service efficiency will be significantly reduced.

FIG. 2 is a diagram showing an example of a combination evaluation value table. FIG. 3 is a diagram showing an example of the allocation management table. FIG. 4 is a diagram illustrating another example of determining the attribute of the in-car user. FIG. 5 is a flowchart showing an example of a processing procedure performed by the group management control device according to the embodiment.

Hereinafter, specific embodiments of an elevator group supervisory control device to which the present invention is applied will be described in detail with reference to the drawings. The embodiment described below is an application example to a group management elevator system called DCS (Destination Control System) in which a user can specify a destination floor at a hall. However, the present invention can be effectively applied to a normal group management elevator system in which a user specifies only a destination direction at a hall.

FIG. 1 is a block diagram showing a functional configuration example of a group management control device 1 according to this embodiment. The group management control device 1 is a device for allocating a landing call to each unit (group management control) while monitoring the operating states of elevators of a plurality of units, and for example, a microcomputer including a CPU, a ROM, a RAM, and the like. And the programs executed by the microcomputer realize the functional units shown in FIG.

As shown in FIG. 1, the group management control device 1 according to the present embodiment includes a database 10, a hall attribute determination unit 2, an in-car attribute determination unit 3, an operating state monitoring unit 4, and an assigned vehicle determination unit 5. A response command output unit 6 and a table updating unit 7. The group management control device 1 is connected to a hall operating device 21 and a hall camera 22 provided in a hall on each floor. Further, the group management control device 1 is connected to an elevator control device 31 for each car that individually controls the operation of the car 30 of each car that is the target of the group management control.

The database 10 holds a combination evaluation value table 11 and an allocation management table 12. The combination evaluation value table 11 stores, for each combination of user attributes, a combination evaluation value indicating whether or not those combinations are suitable for carpooling. Based on this combination evaluation value table 11, the attributes of the hall user who performed the new hall call operation (hall attributes) and the inside of the car that synergize in the car 30 when the hall user gets on the car 30 A combination evaluation value corresponding to a combination with a person's attribute (in-car attribute) is obtained.

FIG. 2 shows an example of the combination evaluation value table 11 held by the database 10. The combination evaluation value table 11 shown in FIG. 2 is a simple example in which user attributes are classified into four types of A: adult male, B: adult female, C: boy, and D: girl. The combination evaluation value is set to a value between 0 and 1, and the larger the value, the less suitable the combination of attributes is for carpooling. For example, the combination of the hall attribute B and the in-car attribute A corresponds to a scene in which an adult woman is riding in a car in which an adult man is riding. In this case, it is assumed that the psychological burden of the hall user on carpooling is large. Therefore, the combination evaluation value is set to a high value of 0.8. On the other hand, a combination in which the hall attribute and the in-car attribute are the same is assumed to have a low psychological burden on the hall user for carpooling, so the combination evaluation value is set to a low value of 0.1.

Note that, in the example of FIG. 2, the user attributes are divided into four broad classifications according to gender and whether or not they are adults for the sake of simplicity. May be divided. For example, the attributes of users are not sorted according to whether they are adults or not, but are classified according to the age of 10 years old, and other classification criteria such as clothes, belongings, body shape of the user, and whether the user is a single person or a group of multiple people. You may add it and divide it finely.

FIG. 3 is a diagram showing an example of the allocation management table 12 held by the database 10. The assignment management table 12 stores information on calls currently assigned to each of a plurality of units subject to group management control. In the present embodiment, since the application example to the DCS is assumed, the allocation management table 12 stores the information of the hall call designating the destination floor. That is, when the number (assignment number) to which the hall call designating the destination floor is assigned is determined by the assignment number determining unit 5 described later, as shown in FIG. 3, the departure floor (that is, Information of the hall call including the floor where the hall call was made), the floor where the user gets off from the car 30, and the attributes of the user are stored in the assignment management table 12 as a new record in association with the assigned number. To be done. The information on the hall call is erased from the allocation management table 12 when the car 30 arrives at the destination floor and the user gets off. The allocation management table 12 illustrated in FIG. 3 is a hall call for transporting a user with attribute A from the 2nd floor to the 3rd floor of B, and a hall call for transporting a user with attribute C from the 3rd floor to the 8th floor. And are assigned.

The hall attribute determination unit 2 determines the attribute (hall attribute) of the hall call user who performed the new hall call operation. For example, the hall attribute determination unit 2 acquires an image of the hall from the hall camera 22 installed in the hall on the floor where the hall user operates the hall operating device 21 to call the hall, The hall attribute is determined by analyzing this image. For the hall attributes, the hall user's image features are extracted from the image acquired from the hall camera 22, and the types of the attributes classified as described above are identified using a discriminator such as a neural network based on the image features. It can be determined by doing. Although the hall attribute is determined using the image of the hall camera 22 here, for example, the hall attribute can be determined by reading the personal information of the hall user stored in the IC card or the IC tag. You can

The information on the hall attributes determined by the hall attribute determination unit 2 is transmitted to the assigned car number determination unit 5. It should be noted that the function of the hall attribute determination unit 2 is provided on the hall side, and the information of the hall attribute determined by the hall attribute determination unit 2 together with the information of the hall call according to the operation of the hall operating device 21 by the hall user, The configuration may be such that it is transmitted to the assigned number determination unit 5.

The in-car attribute determination unit 3 determines, for each of a plurality of units subject to group management control, an attribute of the in-car user (in-car attribute) that synergizes in the car 30 when the hall user gets on the car 30. judge. For example, the in-car attribute determination unit 3 acquires information about a new hall call from the hall operating device 21 operated by the hall user, and refers to the allocation management table 12 held by the database 10 to refer to each car Get information about assigned hall calls. Then, if the new hall call and the stroke of the car 30 overlap among the currently assigned hall calls for each of the plurality of units subject to group management control, the in-car attribute determination unit 3 determines that The attribute of the user of the hall call is determined as the in-car attribute.

Explaining with a specific example, in the state where the allocation management table 12 illustrated in FIG. 3 is held in the database 10, there is a new hall call that designates the sixth floor as the destination floor in the hall on the second floor. To do. In this case, of the hall calls currently assigned to Unit 1, the hall floor call where the departure floor is the B2 floor, the destination floor is the 3rd floor, and the user attribute is the attribute A, is new between the 2nd floor and the 3rd floor. The hall call and the process of the car 30 overlap. Therefore, the in-car attribute determination unit 3 determines the attribute A, which is the user attribute of the hall call, as the in-car attribute of the first car. Similarly, among the hall calls currently assigned to Unit 1, the hall floor call where the departure floor is the 3rd floor, the destination floor is the 8th floor, and the user attribute is attribute C is the new one between the 3rd floor and the 6th floor. The hall call and the process of the car 30 overlap. Therefore, the in-car attribute determination unit 3 also determines the attribute C, which is the user attribute of the hall call, as the in-car attribute of the first car. That is, in the case of this example, the in-car attribute determination unit 3 determines that the in-car attribute of the first car is the attribute A and the attribute C. With respect to other cars, the in-car attributes can be determined by the same method.

Further, the in-car attribute determination unit 3 further determines the number of shared floors in which the hall user and the in-car user synergize in the car 30 with respect to each of the plurality of units subject to group management control. As described above, the shared floor number is the number of floors in which the strokes of the car 30 overlap between the hall call currently assigned to each unit and the new hall call. For example, using the above-mentioned example, when the hall user gets on the car 30 of the first car, the hall user will cooperate with the in-car user of the attribute A between the second floor and the third floor. Therefore, the number of shared floors corresponding to the in-car attribute A of Unit 1 is 2. In addition, when the hall user gets on the car 30 of the first car, the hall user will synergize with the user inside the car of attribute C between the third floor and the sixth floor, so the car inside attribute of the first car The number of shared floors corresponding to C is 4.

Information on the in-car attribute and the number of shared floors for each car determined by the in-car attribute judgment unit 3 is transmitted to the assigned car determination unit 5. Note that the in-car attribute determination unit 3 may be configured to determine only the in-car attribute of each car and not the number of shared floors. In this case, only the in-car attribute information of each car is transmitted from the in-car attribute determination unit 3 to the assigned car determination unit 5.

In the above description, the in-car attribute determination unit 3 uses the allocation management table 12 held in the database 10 to determine the in-car attribute and the number of shared floors for each of a plurality of vehicles. As shown in FIG. 4, when an in-car camera 32 is installed in the car 30 of each car, a method similar to that of the hall attribute determination unit 2 is used by using an image captured by the in-car camera 32. It is also possible to determine the attributes of users in the car (attributes in the car). That is, when the information on the new hall call is transmitted from the hall operating device 21 operated by the hall user, the in-car attribute determination unit 3 causes the in-car camera 32 installed in the car 30 of each unit to detect the car 30. Acquire a video of the inside. Then, the in-car attribute determination unit 3 assumes that the user who is in the car 30 at this point is an in-car user who synergizes with the hall user in the car 30. By using the acquired video, the attribute of the in-car user (in-car attribute) can be determined by the same method as the hall attribute determination unit 2.

In addition, when the in-car camera 32 is capturing an image of a user who performs an operation of designating the destination floor by the in-car operation device 33 installed in the car 30, the in-car attribute determination unit 3 operates as shown in FIG. As shown in, by acquiring the operation information of the in-car operation device 33 together with the image captured by the in-car camera 32, the destination floor of the user in the car 30 can be known, and this user can use the platform. It will be possible to judge whether or not the user will be synergistic with the user. In this case, the in-car attribute determination unit 3 can more accurately determine the in-car attribute based on the image captured by the in-car camera 32.

The operating state monitoring unit 4 collects information indicating the operating state (current position and traveling direction of the car 30, whether the car is moving or stopped, etc.) from the elevator control device 31 of each car that is the target of group management control. In addition, the operating status of each unit will be comprehensively monitored. Then, the operation state monitoring unit 4 transmits to the assigned number determining unit 5 information necessary for the assigned number determining unit 5 to calculate a basic evaluation value for each number, which will be described later.

Further, the operating state monitoring unit 4 has a function of updating the allocation management table 12 held in the database 10 according to the operating state of each unit. That is, the operating state monitoring unit 4 of the hall call information for each unit stored in the allocation management table 12, the hall call which has completed the response when the car 30 arrives at the destination floor and the user gets off. Delete the information in.

The assigned number determination unit 5 monitors the hall attributes determined by the hall attribute determination unit 2, the in-car attributes and carpool floors of each unit determined by the in-car attribute determination unit 3, and the operating state monitoring unit 4. The allocation evaluation value for each of the plurality of units subject to group management control is calculated based on the operating state of each unit. Then, the assigned number determination unit 5 determines the assigned number to which a new hall call is assigned among a plurality of number based on the calculated assignment evaluation value for each number.

For example, the assigned car determining unit 5 combines the hall attributes determined by the hall attribute determining unit 2 with the car inside attributes determined by the car inside attribute determining unit 3 for each of the plurality of units subject to group management control. Is compared with the combination evaluation value table 11 held in the database 10 to obtain the combination evaluation value for each of the plural machines. At this time, when a plurality of car internal attributes are determined for one car, a combination evaluation value for each individual car internal attribute is obtained. In addition, the assigned number determination unit 5 obtains a value obtained by dividing the number of floors of the shared pool determined by the attribute determination unit 3 in the car by the total number of floors of the building as the degree of shared pool, and the combined evaluation value is shared. The degree is multiplied to calculate the carpool evaluation value for each of the plurality of units. At this time, if a plurality of car attributes and carpool floors are determined for one car, the carpool evaluation value for each car attribute is calculated.

Explaining with a concrete example, in the state where the combination evaluation value table 11 illustrated in FIG. 2 and the allocation management table 12 illustrated in FIG. It is assumed that there is a new hall call designated as a floor, and the hall attribute determination unit 2 determines that the hall user attribute (hall attribute) is attribute B. In this case, as described above, the in-car attribute determination unit 3 determines that the attributes (in-car attributes) of the in-car user of the first car are attribute A and attribute C, and the in-car attribute A of the first car is determined. The corresponding number of shared floors is 2, and the number of shared floors corresponding to the in-car attribute C of the first car is determined to be 4.

Here, if the total number of floors of the building is 12, the degree of carpooling of the in-car attribute A of the first car is 1/6 by dividing the number of shared floors 2 by the total number of floors 12. Since the combination evaluation value for the combination of the hall attribute B and the in-car attribute A is 0.8, the carpool evaluation value for the in-car attribute A of Unit 1 is 0.8 multiplied by 1/6, It becomes about 0.13. Further, the degree of carpooling of the attribute C in the car of the first car is 1/3 by dividing the number of floors 4 of carpooling by the total number of floors 12. Since the combination evaluation value for the combination of the hall attribute B and the in-car attribute C is 0.2, the carpool evaluation value for the in-car attribute C of Unit 1 is 0.2 times 1/3, It becomes about 0.07.

The assigned number determination unit 5 uses the information acquired from the operating state monitoring unit 4 to calculate a basic evaluation value for each of the multiple units subject to group management control, and the basic evaluation value is calculated as described above. The assigned evaluation value for each of the plurality of units is calculated by adding the carpool evaluation value. When a plurality of carpool evaluation values are calculated for one car, the plurality of carpool evaluation values are added to the basic evaluation value of the car. For example, in the above example, since the carpool evaluation value of 0.13 for the in-car attribute A and the carpool evaluation value of 0.07 for the in-car attribute C are calculated as the carpool evaluation value of the first car, allocation of the first car The evaluation value is a value obtained by adding 0.13 and 0.07 to the basic evaluation value.

The basic evaluation value is an evaluation value according to the length of the waiting time for the landing of each unit (that is, the time required for the car 30 to arrive at the landing when the unit responds to the landing call), for example, It is calculated by multiplying the hall waiting time by a predetermined coefficient α. The basic evaluation value may be calculated by adding parameters other than the length of the hall waiting time, such as the number of users in the car 30.

The method of calculating the allocation evaluation value described above is an example, and the present invention is not limited to this example. The allocation evaluation value may be calculated in consideration of at least the combination of the hall attribute and the in-car attribute. For example, in the above example, the combination evaluation value according to the combination of the hall attribute and the in-car attribute is multiplied by the degree of carpool according to the number of floors of the carpool, and the carpool evaluation value is calculated, and the basic evaluation value is carpooled. Although the evaluation value is added to calculate the allocation evaluation value, more simply, the combination evaluation value according to the combination of the hall attribute and the car attribute is added to the basic evaluation value to calculate the allocation evaluation value. Good. In this case, it is not necessary to determine the number of shared floors, and it is possible to more easily calculate the allocation evaluation value in consideration of the combination of the hall attribute and the in-car attribute.

The assigned number determination unit 5 determines the assigned number to which a new hall call is assigned among the plurality of units based on the assignment evaluation value calculated as described above for each of the plurality of units subject to group management control. To do. In the above example, since the allocation evaluation value of a value that is low enough to be suitable for allocating a new hall call is calculated, the allocation machine determination unit 5 determines that the calculated allocation evaluation value is the smallest among a plurality of machines. The machine that takes the value of is determined as the allocated machine. Information on the assigned number determined by the assigned number determining unit 5 is transmitted to the response command output unit 6. Further, when the assigned number determining unit 5 determines the assigned number to which the new hall call is assigned, the information of the new hall call (starting floor, destination floor, user attribute) is associated with the assigned number, and the assignment management table is displayed. Store in 12.

The response command output unit 6 outputs a hall call response command to the elevator control device 31 of the assigned number determined by the assigned number determination unit 5. The elevator control device 31 of the assigned car controls the operation of the car 30 in response to the hall call response command from the response command output unit 6 and responds to the hall call.

The table updating unit 7 determines whether or not the hall user actually gets on the car 30 of the assigned number after the car 30 of the assigned number determined by the assigned unit determination unit 5 arrives at the hall where the new hall call is made. Depending on whether or not, the combination evaluation value stored in the combination evaluation value table 11 is updated. Whether or not the hall user has boarded the car 30 of the assigned car can be determined by, for example, analyzing an image of the hall photographed by the hall camera 22.

For example, when it is determined that the number of the hall user attribute (hall attribute) is attribute B and the in-car user attribute (in-cab attribute) is attribute C is the assigned number, the table updating unit 7 determines the assigned number. When the hall user does not board the car, the combination evaluation value corresponding to the combination of the hall attribute B and the in-car attribute C among the combination evaluation values stored in the combination evaluation value table 11 is increased. Update. Further, when the hall user gets on this assigned car, the combination evaluation value corresponding to the combination of the hall attribute B and the in-car attribute C may be updated to be lowered.

Further, the table updating unit 7 does not update the combination evaluation value each time the car 30 of the assigned car determined by the assigned car determination unit 5 arrives at the landing where a new landing call was made, but rather, the combination evaluation value For each combination with the interior attribute, a boarding history indicating whether the hall user has boarded the car 30 of the assigned car is accumulated for a predetermined number of times, and the combination evaluation value is updated at an arbitrary timing based on this boarding history. You may do it. In this case, the table updating unit 7 determines, for each combination of the hall attribute and the in-car attribute, the combination evaluation value according to the ratio of the number of times the hall user gets on the car 30 of the assigned car and the number of times that the hall user does not board. Determines the degree of update of. That is, when the number of times that the hall user did not board the car 30 of the assigned car is greater than the number of times that the car is assigned, the combination evaluation value is updated so that the combination evaluation value is increased. Enlarge. If the number of times the hall user has boarded the car 30 of the assigned car is greater than the number of times the passenger has not boarded the car, the combination evaluation value is updated to be smaller, and the larger the number of times the passenger is boarded, the greater the degree of update. ..

As described above, the table updating unit 7 updates the combination evaluation value stored in the combination evaluation value table 11, whereby the actual boarding history can be reflected to optimize the combination evaluation value.

Next, the operation of the group supervisory control device 1 configured as described above will be described with reference to FIG. FIG. 5 is a flowchart showing an example of a processing procedure by the group management control device 1 according to the present embodiment. The series of processes shown in the flowchart of FIG. 5 is started each time the hall user operates the hall operating device 21 to make a new hall call.

When a new hall call operation is performed by the hall user, first, the hall attribute determination unit 2 analyzes the image of the hall camera 22, for example, to determine the hall user attribute (hall attribute) (step. S101).

In addition, the in-car attribute determination unit 3 refers to, for example, the allocation management table 12 held by the database 10, for each of a plurality of units subject to group management control, the attribute of the in-car user (in-car attribute). And the number of shared floors is determined (step S102).

Next, the assigned number determination unit 5 has the combination evaluation value table 11 held by the database 10, the hall attributes determined in step S101, the in-car attributes and the number of shared floors for each number determined in step S102. Based on the above, the carpool evaluation value for each of the plurality of units subject to group management control is calculated (step S103). Then, the assigned number determination unit 5 determines the group management control target by using the reference evaluation value of each number calculated based on the information from the operating state monitoring unit 4 and the carpool evaluation value calculated in step S103. Then, an allocation evaluation value for each of the plural units is calculated (step S104).

Next, the assigned number determination unit 5 determines, based on the assigned evaluation value calculated in step S104, the assigned number that responds to the new hall call among the multiple numbers subject to group management control (step S105). , The information of the assigned machine is transmitted to the response command output unit 6. Further, the assigned machine determining unit 5 stores the information of the hall call in the assignment management table 12 held by the database 10 in association with the assigned machine (step S106).

Then, the response command output unit 6 outputs a hall call response command to the elevator control device 31 of the assigned car (step S107), and the series of processes shown in the flowchart of FIG. 5 ends.

As described above in detail with reference to specific examples, the group management control device 1 according to the present embodiment, the attribute of the hall user who performed the operation of the new hall call (hall attribute), and its use By using the attribute of the user in the car (attribute in the car) that synergizes in the car 30 when the person gets on the car 30, the allocation evaluation value for each of the plurality of units subject to group management control is calculated, Based on this allocation evaluation value, the allocation machine to which a new hall call is allocated is determined. Therefore, according to the group management control device 1 according to the present embodiment, the optimum number of cars, which takes into account the psychological burden of the hall users for carpooling in the car 30, is assigned to the hall calls, and the reduction in service efficiency is suppressed. can do.

Further, in the present embodiment, the carpool evaluation value is based on the combination evaluation value corresponding to the combination of the hall attribute and the in-car attribute and the number of carpool floors that the hall user and the car user synergize in the car 30. Is calculated, and the joint evaluation value is added to the basic evaluation value according to the length of the waiting time for the hall, and the allocation evaluation value of each unit is calculated. Therefore, the psychological burden of the hall user for carpooling can be accurately reflected in the allocation evaluation value of each car.

The embodiment described above can be implemented with various modifications. For example, although the embodiment described above assumes an application example to the DCS, the present invention can also be applied to a normal group management elevator system in which only the destination direction is designated by the hall call. In this case, the destination floor of the hall user can be estimated, for example, based on the past driving history of the elevator. That is, the user who gets on the car 30 from the hall on each floor keeps as a driving history the floor at which the user got off the car 30, and the floor where a new hall call was made gets on the floor. It is possible to presume that the floor with the highest frequency of getting off the user is the destination floor of the hall user who made the new hall call. In addition, the destination floor of the user in the car can be determined by analyzing the image captured by the in-car camera 32, as described above.

In addition, when the shared floor number is not used in the calculation of the assigned evaluation value for each unit, as described above, the number of users who are in the car 30 of each unit at the time when a new hall call is made is determined. Assuming that the user is in the car, the combination evaluation value corresponding to the combination of the hall attribute determined by analyzing the image of the hall camera 22 and the in-car attribute determined by analyzing the image of the in-car camera 32 is displayed. You may use and calculate the allocation evaluation value of each machine. As a result, it is possible to more easily determine the assigned car in consideration of the psychological burden of the hall user on carpooling.
