    DESCRIPTION OF EMBODIMENTS
  • (1) Configuration of Elevator Management System According to This Embodiment Referring to Fig. 1, the reference numeral 1 represents an elevator management system according to this embodiment. This elevator management system 1 is configured by including a management server 2 for managing a plurality of elevators 3. The management server 2 and the plurality of elevators 3 are connected via a communication path 19 such as an intranet.
  • The management server 2 is a management apparatus that acquires operation data of each elevator 3 via a receiving circuit, learns the operation status of each elevator 3 from the acquired operation data, and manages the operation of each elevator 3 by outputting management information via an output circuit. The management server 2 is configured by including a CPU (Central Processing Unit) 4, an auxiliary storage apparatus 5, and a memory 6.
  • The CPU 4 is a processor (controller) that controls the operation of the entire management server 2. The auxiliary storage apparatus 5 is composed of, for example, large-capacity nonvolatile storage devices such as hard disk drives and SSDs (Solid State Drives) and is used to store programs and data for a long period of time. Some of storage areas provided by this auxiliary storage apparatus 5 are used as an operation data table TB10 and a learning data table TB20 described later.
  • The memory 6 is composed of, for example, a volatile semiconductor memory, is also used as a work memory for the CPU 4, and includes an operation storage module 7, an operation learning module 8, a route determination module 9, and a route instruction module 10. Incidentally, the memory 6 may accumulate and record the operation data as appropriate.
  • Each elevator 3 operates to lift and lower a cage 12 in a hoistway installed in a building between boarding places provided respectively at floor levels of, for example, a first floor to a seventh floor as illustrated in Fig. 2.
  • This cage 12 is attached to one end side of a primary rope 13, to the other end side of which a counterbalancing weight 14 is attached. Furthermore, the primary rope 13 is wound around a hoist 15. The hoist 15 is a hoisting mechanism for driving the cage 12 to lift and lower it and is installed together with a control apparatus for controlling hoisting operation of the cage 12 (hereinafter referred to as an elevator control apparatus) 11 in a machine room provided above the hoistway.
  • The elevator control apparatus 11 (Fig. 1) is a computer apparatus for controlling the operation of the cage 12 and controls the hoist 15 to lift and lower the cage 12 in response to a passenger's operation (cage call information) of a call button 16 (Fig. 2) provided at a boarding place.
  • The elevator 3 is inefficient because it is difficult for the elevator 3 to judge in which time slot and through which route the cage 12 does not have to operate; however, the elevator 3 is normally operated in such a manner that the cage 12 can be operated from the highest floor to the lowest floor. According to the present invention, the elevator management system 1 is equipped with a learning function in order to make the above-described judgment.
  • Next, the learning function mounted in the management server 2 of the elevator management system 1 will be explained. Incidentally, the learning function performs, for example, deep learning.
  • The learning function of the elevator management system 1 learns an operation tendency by predicting the operation status of the call button 16 and a destination floor designating button of each cage 12 a specified amount of time later (for example, 5 minutes later as a cycle for the cage 12 to make one run along a traveling route) after accepting the cage call information of each floor level and/or the operation of the destination floor designating button of each cage 12 (destination floor designating information).
  • Fig. 3 illustrates an example of the learning function. Arithmetic operation are performed by applying weighting to between neurons (circles in Fig. 3) in adjacent layers (columns in Fig. 3). Regarding this learning function, after an array of as many dimensions as the number of inputs to the call button 16 of each floor level and the destination floor designating button of each cage 12 is input, the management server 2 performs specified arithmetic operations in a plurality of hidden layers and an output layer. Incidentally, there is one input layer for a floor level where the input is performed; and there is one output layer for a floor level where the output is performed. Also, a plurality of hidden layers exist between the input layer and the output layer.
  • Then, as a result of the arithmetic operations, the management server 2 outputs an array of as many dimensions as the number of inputs to the call button 16 at each floor level and the destination floor designating button of each cage 12. Incidentally, a specified arithmetic operation(s) in the hidden layers is, for example, an arithmetic operation(s) using activation functions such as a Sigmoid function, a hyperbolic tangent function, and a ramp function. Furthermore, a specified arithmetic operation(s) in the output layer is, for example, an arithmetic operation(s) using a Softmax function and so on.
  • Referring to Fig. 3, when the cage 12 moving up is called at the 1st floor and the cage 12 moving up and the cage 12 moving down are called at the 2nd floor, the management server 2 predicts how the cage 12 will be called in the next cycle, according to this learning function.
  • In this case, the management server 2 predicts that the cage 12 moving up will be called at the 2nd floor and the cage 12 moving down will be called at the 4th floor in the next cycle.
  • Incidentally, referring to Fig. 3, "○" represents a case where the button is pressed; and "×" represents a case where the button is not pressed. Furthermore, regarding each floor level, "↑" represents a button when calling the cage 12 moving up at the boarding place; "↓" represents a button when calling the cage 12 moving down at the boarding place; and "→" represents a button when a passenger is getting off from the cage 12 at the relevant floor. Incidentally, since Fig. 3 illustrates an example of the case where there is only one cage 12, there is one row of "→" for each floor; however, there may be a plurality of cages 12.
  • In the case of the prediction in Fig. 3, the management server 2 predicts, by means of deep learning, that the cage 12 will not be called from the 4th floor to the 7th floor during a period of time required for the cage 12 to make one run along the route. The management server 2 issues an instruction to the elevator control apparatus 11 to operate the cage 12 along an operation route with the 4th floor as a destination floor as indicated with a solid line in Fig. 4. Specifically speaking, the management server 2 issues an instruction to the elevator control apparatus 11 to invert a traveling direction of the cage 12 after waiting time for a passenger(s) to get on and/or off the cage 12 at the 4th floor. Incidentally, a broken line in Fig. 4 indicates a conventional operation route and the cage reaches to the 7th floor which is the highest floor according to the conventional operation.
  • As means for implementing the above-described learning function, as illustrated in Fig. 1, the memory 6 of the management server 2 stores the operation storage module 7, the operation learning module 8, the route determination module 9, and the route instruction module 10 and the auxiliary storage apparatus 5 of the management server 2 stores the operation data table TB10 and the learning data table TB20.
  • The operation storage module 7 is a program having a function that acquires the operation data from the elevator control apparatus 11 of each elevator 3, for example, every day and stores the acquired operation data in the operation data table TB10.
  • The operation learning module 8 is a program that performs learning as illustrated in Fig. 3 on the basis of the operation data acquired from the operation data table TB10, for example, for one year every year and changes, for example, necessary values for learning such as a weight value as illustrated in Fig. 3. Furthermore, the operation learning module 8 records the status of the call button 16 at each floor level and the status of the destination floor designating button of each cage 12 which are calculated as a learning result (the learning result) in the learning data table TB20. Incidentally, the learning result is calculated for each combination of the status of the call button 16 at each arbitrary floor level and the status of the destination floor designating button of each cage 12.
  • The route determination module 9 is a program that acquires the learning result from the learning data table TB20 and determines the operation route of the cage 12. The route determination module 9 derives a route which can be omitted and along which the cage 12 does not have to be operated, from each learning result and determines a route which does not pass through the above-mentioned route, as a shortened route, to be the operation route of the cage 12.
  • For example, in a case of the learning result as illustrated in an input row and an output row in Fig. 6, the route determination module 9 recognizes that it is unnecessary to pass through the 2nd floor to the 7th floor regarding either the input row or the output row.
  • Accordingly, the route determination module 9 determines the shortened route, which does not pass through the 2nd floor to the 7th floor, as the operation route of the cage 12. Incidentally, if there is no route which can be omitted, the route determination module 9 determines the normal route along which the cage 12 moves between the lowest floor and the highest floor, as the operation route of the cage 12.
  • The route instruction module 10 is a program that corrects the operation route determined by the route determination module 9 according to the position, traveling direction, etc. of each cage which are given from the elevator control apparatus 11 of each elevator 3. For example, when the call button 16 is pressed within the operation route where the cage 12 has not passed through yet during the operation of the cage 12, or when something which has not occurred yet is predicted while the door for the cage 12 is open, the operation route of the cage 12 is corrected and this corrected operation route is transmitted as the management information to the elevator control apparatus 11 of the elevator 3.
  • Incidentally, when the operation route of the cage 12 does not have to be corrected, the route instruction module 10 transmits the operation route determined by the route determination module 9, without any change, to the elevator control apparatus 11 of the elevator 3. Furthermore, the route instruction module 10 determines one or more cages 12 to be operated from among the plurality of cages 12 according to the operation route determined by the route determination module 9.
  • The operation data table TB10 stores, as illustrated in Fig. 5, the status of the call button 16 at each floor level (the cage call information) and the status of the destination floor designating button of each cage 12 (the destination floor designating information) as the operation data every 5 minutes (time required to make one run along the route). Incidentally, "○", "×", "↑", "↓", and "→" in Fig. 5 have the same meanings as those in Fig. 3.
  • Similarly, the learning data table TB20 stores, as illustrated in Fig. 6, the status of the call button 16 at each arbitrary floor level and the status of the destination floor designating button of each cage 12 as inputs and the status of the call button 16 at each floor level and the status of the destination floor designating button of each cage 12 five minutes later (time required to make one run along the route) as outputs. Incidentally, "○", "×", "↑", "↓", and "→" in Fig. 6 have the same meanings as those in Fig. 3.
  • (2) Various Kinds of Processing by Management Server
  • Next, various kinds of processing executed by the above-described management server 2 will be explained. Incidentally, a processing subject of the various kinds of processing will be hereinafter explained as a "program"; however, it is needless to say that practically the CPU 4 executes the processing based on the "program."
  • Fig. 7 illustrates a processing sequence for operation data acquisition processing executed by the operation storage module 7. The operation storage module 7 acquires the operation data from the elevator control apparatus 11 of each elevator 3 according to the processing sequence illustrated in this Fig. 6.
  • Practically, the operation storage module 7 starts the operation data acquisition processing illustrated in this Fig. 7, for example, at a set time every day.
  • Then, the operation storage module 7 firstly acquires the operation data for one day from the elevator control apparatus 11 of each elevator 3 (S11). Subsequently, the operation storage module 7 stores the operation data for one day in the operation data table TB10 (S12) and terminates the operation data acquisition processing.
  • Fig. 8 illustrates a processing sequence for operation data learning processing executed by the operation learning module 8. The operation learning module 8 learns the status of the call button 16 at each floor level and the status of the destination floor designating button of each cage 12 five minutes later (time required to make one run along the route) (the learning result) with respect to the status of the call button 16 at each arbitrary floor level and the status of the destination floor designating button of each cage 12 in accordance with the processing sequence illustrated in this Fig. 8 based on the operation data acquired from the operation data table TB10.
  • Practically, the operation learning module 8 starts the operation data learning processing, for example, at a set time of the year every year.
  • Then, the operation learning module 8 firstly acquires the operation data for one year from the operation data table TB10 and learns based on the acquired operation data (S15). Subsequently, the operation learning module 8 stores the learning result as learning data in the learning data table TB20 (S16) and terminates the operation data learning processing.
  • Fig. 9 illustrates a processing sequence for operation route determination processing executed by the route determination module 9. The route determination module 9 determines the operation route of the cage 12 in accordance with the processing sequence illustrated in this Fig. 9.
  • Practically, after the operation data learning processing terminates, the route determination module 9 starts the operation route determination processing illustrated in this Fig. 9.
  • Then, the route determination module 9 firstly acquires the learning data from the learning data table TB20 (S21). Subsequently, the route determination module 9 judges whether or not there is any route which can be omitted, with respect to each learning result (S22). When a negative result is obtained in this judgment, the route determination module 9 transmits the normal route as the operation route to the route instruction module 10 and terminates the operation data learning processing.
  • On the other hand, when an affirmative result is obtained in the judgment of step S22 because there is a route which can be omitted, the route determination module 9 generates a shortened route by omitting that route (S23), transmits the shortened route to the route instruction module 10, and terminates the operation data learning processing.
  • Fig. 10 illustrates a processing sequence for operation instruction processing executed by the route instruction module 10. The route instruction module 10 designates the operation route to the cage 12 in accordance with the processing sequence illustrated in this Fig. 10.
  • Practically, after receiving the passenger's operation on the call button 16 from the elevator control apparatus 11 of the elevator 3, the route instruction module 10 starts the operation route correction processing during operation as illustrated in this Fig. 10.
  • Then, the route instruction module 10 firstly determines the cage 12 to be operated (S25). Subsequently, the route instruction module 10: transmits the operation route to the elevator control apparatus 11 which controls the relevant cage 12 (S26); and terminates the operation instruction processing. Then, the elevator control apparatus 11 which has received the operation route operates the cage 12 in accordance with this operation route.
  • Fig. 11 illustrates a processing sequence for operation route correction processing during operation, which is executed by the route instruction module 10. The route instruction module 10 corrects the operation route of the cage 12 in accordance with the processing sequence illustrated in this Fig. 11.
  • Practically, after the operation instruction processing terminates and the route instruction module 10 receives the passenger's operation on the call button 16 at a boarding place within the operation route of the cage 12, whose operation is designated by this operation instruction processing, from the elevator control apparatus 11, the route instruction module 10 starts the operation route correction processing during operation as illustrated in this Fig. 11.
  • Then, the route instruction module 10 firstly acquires the position and traveling direction of the cage 12 from each elevator control apparatus 11 and judges whether there is any cage 12 approaching to the relevant boarding place or not (S31). When an affirmative result is obtained in this judgment because there is a cage 12 approaching to that boarding place, the route instruction module 10 terminates the operation route correction processing during operation. Since this approaching cage 12 stops at the relevant boarding place, the control by the management server 2 becomes no longer necessary.
  • On the other hand, when a negative result is obtained in the judgment of step S31 because there is no cage 12 approaching, the route instruction module 10 selects a cage 12 closest to the boarding place (S32). Subsequently, the route instruction module 10: transmits an instruction to the elevator control apparatus 11, which controls the selected cage 12, to invert the traveling direction of the relevant cage 12 (S33); and terminates the operation route correction processing during operation.
  • Fig. 12 illustrates a processing sequence for operation route correction processing executed by the route instruction module 10 while the door is open. The route instruction module 10 corrects the operation route of the cage 12 in accordance with the processing sequence illustrated in this Fig. 12.
  • Practically, after the operation instruction processing terminates and the route instruction module 10 receives a button pressing operation, which has not occurred yet with respect to the cage 12 (and which should have occurred according to the prediction based on the learning result), from the elevator control apparatus 11 while the door of the cage 12 which has been designated to operate according to this operation instruction processing is opened (hereinafter referred to as door-opened time), the route instruction module 10 starts the operation route correction processing while the door is open as illustrated in this Fig. 12.
  • Then, the route instruction module 10 firstly judges whether or not time elapsed from the time when the button pressing operation should have occurred to this door-opened time is equal to or less than a specified value (S41). When the specified amount of time has passed and the route instruction module 10 judges that an error in the prediction based on the learning result cannot be corrected, and when a negative result is thereby obtained in this judgment, the route instruction module 10 terminates the operation route correction processing while the door is open.
  • On the other hand, when the specified amount of time has not passed and the route instruction module 10 judges that the error in the prediction based on the learning result can be corrected, and when an affirmative result is thereby obtained in the judgment of step S41, the route instruction module 10: transmits an instruction to the elevator control apparatus 11, which controls this cage 12, to extend the time to open the door (S42); and then terminates the operation route correction processing while the door is open.
  • (3) Advantageous Effects of This Embodiment
  • With the elevator management system 1 according to this embodiment as described above, the management server 2 issues the instruction to each elevator 3 to operate by omitting any route which can be omitted, by predicting, based on the learning data, how each elevator will operate in the next cycle.
  • Therefore, this elevator management system 1 makes it possible to apply the operation according to the status of use to the cage(s) 12 without any alterations or the like of programs and the cage(s) 12 can be operated efficiently.
  • (4) Other Embodiments
  • Incidentally, the aforementioned embodiment has described the case where the elevator management system 1 to which the present invention is applied is configured as illustrated in Fig. 1; however, the present invention is not limited to this example and a wide variety of other configurations can be applied as the configurations of these elevator management systems.
  • For example, as illustrated in Fig. 13, an elevator management system 20 may be configured to connect the management server 2 with each elevator 3 via a communication network 21 such as the Internet. In this case, the management server 2 is a cloud server or a server apparatus installed at a data center. The management server 2 is connected to the elevators 3 via the communication network 21, communication equipment 22, 23 such as a switching hub and a router, and a communication path 24 such as an intranet.
  • In the case of the configuration as illustrated in Fig. 1, an inside space of the hoistway of the elevators 3 or a machine room is assumed as a place to install the management server 2, but it is sometimes difficult to install large-capacity data storage devices capable of saving the operation data for one year and the server apparatus for implementing the deep learning at such a place. However, the elevator management system 20 can apply the present invention even in such a case by employing the configuration as illustrated in Fig. 13.
  • Furthermore, the elevator management system 20 is installed at, for example, another building operated with the same working hours or business hours by being connected to the outside via, for example, the Internet and can acquire the operation data of the elevators 3 which operate in similar manners. Accordingly, the elevator management system 20 can acquire many pieces of operation data for learning and enhance the accuracy of learning.
  • Furthermore, as the elevator management system 20 is connected to the outside via, for example, the Internet and uses weather data and operation information of public transportation facilities as information for learning, it can enhance the accuracy of learning.
  • Furthermore, regarding an elevator management system 30 as illustrated in Fig. 14, a cloud server 35 for calculating learning data may be connected to a management server 31, which is a server apparatus, and each elevator 3 via the communication network 21 and communication equipment 37, 39 such as a switching hub and a router. Incidentally, the cloud server 35 is composed of a cloud server, a data center, and so on.
  • As a result of employing the configuration illustrated in Fig. 14, processing mainly focused on the operation data learning processing which requires transfer of the operation data with heavy load and learning processing can be executed by the cloud server 35 with high performance; and processing mainly focused on the operation instruction processing which requires frequent communication with the elevators 3 and for which any delay in the communication would be fatal can be executed by the management server 31.
  • Accordingly, the elevator management system 30 can reduce any influence caused by the delay in the communication and can be installed also in a relatively limited installment space. Incidentally, the acquisition of the learning data by a learning data acquisition module 34 and the operation instruction to the relevant elevator 3 can be implemented promptly by installing the management server 31 in a DMZ (demilitarized zone).
  • Furthermore, regarding an elevator management system 50 as illustrated in Fig. 15, communication via the communication equipment 37 (Fig. 14) such as the switching hub and the router becomes no longer necessary by providing a management server 51, which is a server apparatus, with a communication module 54. Therefore, the present invention can be applied even in a case where the switching hub, the router, and so on cannot be used due to the environment where the switching hub, the router, and so on are not installed, or due to some security reason. Incidentally, the configuration in Fig. 15 can return to the conventional operation of the elevators 3 simply by removing the management server 51.
  • Furthermore, when it is difficult to download the learning data via the communication network, an auxiliary storage apparatus 63 such as an SD card in which learning data TB30 is recorded may be connected to an elevator management system 60 as illustrated in Fig. 16. The auxiliary storage apparatus 63 updates the learning data TB 30 when a customer engineer who periodically performs maintenance and inspection of the elevators 3 performs carrying maintenance or performs inspection. The learning data TB30 is created by copying the learning data TB20. Incidentally, the configuration in Fig. 16 can return to the conventional operation of the elevators 3 simply by removing a management server 61 which is a server apparatus.
  • Furthermore, the aforementioned embodiment has described the case where the deep learning is used as a learning means; however, the present invention is not limited to this example and a statistic means such as regression analysis may be used and machine learning other than the deep learning may be used.
  • Furthermore, the aforementioned embodiment has described the case where the pressed state of the call button 16 at each floor level and the destination floor designating button of each cage 12 after one run along the route is predicted based only on the pressed state of the call button 16 at each floor level and the destination floor designating button of each cage 12; however, the present invention is not limited to this example and season information such as spring, summer, fall, and winter, year information such as a year when the Olympics will be held or a leap year, time slot information such as morning, noon, and night, and so on may be reflected.
  • Furthermore, the aforementioned embodiment has described the case where no consideration is paid to local information within the building; however, the present invention is not limited to this example and the location information such as information about the use of meeting rooms in the building may be acquired through the communication path 19 and be reflected in the prediction result.
