Embodiment 1.
FIG. 1 is a diagram showing an example of an elevator system 1 according to the first embodiment. The elevator system 1 includes a group management device 2. The group management device 2 manages a plurality of elevator devices 3 as a group. In the present embodiment, as the simplest example, an example in which the elevator system 1 includes two elevator devices 3 is shown. That is, the group management device 2 manages the A unit and the B unit. The group management device 2 may manage three or more elevator devices 3.

Each elevator device 3 includes a car 4 and a control device 30. The car 4 moves up and down the hoistway. The car 4 is suspended from the hoistway by the main rope 5. The main rope 5 is wound around the hoisting machine 6. The hoisting machine 6 drives the car 4. The control device 30 controls the hoisting machine 6. That is, the movement of the car 4 is controlled by the control device 30.

The car 4 includes a door 7, a door motor 8, a door switch 9, and an operation panel 10. The door motor 8 drives the door 7. The control device 30 controls the door motor 8. That is, the opening / closing operation of the door 7 is controlled by the control device 30. The door switch 9 detects that the door 7 is in a particular fully closed position. If the door 7 is in the fully closed position, the fully closed information is transmitted from the door switch 9 to the control device 30. This fully closed information is an example of information indicating the position of the door 7. The car 4 may be equipped with a door switch for detecting that the door 7 is in a specific fully open position.

The operation panel 10 includes a destination button, a door open button, and a door close button. The operation panel 10 may be provided with other buttons. The operation panel 10 may include a switch. When the destination button provided on the operation panel 10 is pressed, the destination button information corresponding to the pressed destination button is transmitted from the operation panel 10 to the control device 30. The destination button information from the operation panel 10 is a registration request for a car call. Further, when the door open button is pressed, the door open button information is transmitted from the operation panel 10 to the control device 30. When the door close button is pressed, the door close button information is transmitted from the operation panel 10 to the control device 30. When the switch provided on the operation panel 10 is operated, the switch information corresponding to the operated switch is transmitted from the operation panel 10 to the control device 30.

Each elevator device 3 is provided with a landing device for detecting that the car 4 is arranged according to the height of the landing. The landing device includes a photoelectric sensor 11 and a plate 12. The photoelectric sensor 11 is provided in the car 4. The plate 12 is provided on the hoistway. The plate 12 is arranged according to the height of each landing where the car 4 stops. When the photoelectric sensor 11 detects the plate 12, the photoelectric sensor 11 transmits the plate information corresponding to the detected plate 12 to the control device 30. This plate information is an example of information indicating the position of the car 4.

Each elevator device 3 includes a speed governor 13. When the speed of the car 4 exceeds the reference speed, the speed governor 13 forcibly stops the car 4. The reference speed is preset. The governor 13 includes a governor 14 and an encoder (not shown). The governor 14 rotates in synchronization with the movement of the car 4. The encoder detects the rotation angle of the speed governor 14. The encoder transmits the detected information to the control device 30. The detection information from the encoder is an example of information indicating the running of the car 4. The hoisting machine 6 may be provided with an encoder having the same function as that of the encoder.

The functions of the control device 30 will be described later.

The elevator system 1 includes an operation panel 15. The operation panel 15 is provided at each landing where the car 4 stops. As an example, the operation panel 15 includes an upper button and a lower button. When the button provided on the operation panel 15 is pressed, the landing button information corresponding to the pressed button is transmitted from the operation panel 15 to the group management device 2. The landing button information from the operation panel 15 is a registration request for a landing call.

The group management device 2 includes an allocation unit 21, a prohibition unit 22, and a specific unit 23. FIG. 2 is a diagram for explaining the function of the control device 30. The control device 30 of each elevator device 3 includes a storage unit 31, an operation control unit 32, an information input unit 33, an information recording unit 34, a detection unit 35, an extraction unit 36, a specific unit 37, a determination unit 38, and an adjustment unit 39. Be prepared.

Hereinafter, the operation of the elevator system 1 will be described with reference to FIGS. 3 to 7. In the following description, when it is necessary to distinguish the elements provided in the elevator device 3 for each unit, A or B is added to the code representing each element. For example, Unit A includes a car 4A and a control device 30A. Unit B is equipped with a car 4B and a control device 30B.

FIG. 3 is a flowchart showing an operation example of the group management device 2. In the group management device 2, it is determined whether or not the landing button information is received from the operation panel 15 (S101). For example, when the user presses the upper button of the operation panel 15 to register the call at the landing on the first floor of the building, the group management device 2 outputs the landing button information indicating that the upper button is pressed on the first floor. Receive (Yes in S101).

The allocation unit 21 determines a car 4 to be made to respond to the landing button information from the operation panel 15, that is, a car 4 to which the landing call is assigned (S102). For example, the allocation unit 21 determines the allocation car based on the registration status of the landing call and the car call in each elevator device 3. Further, the allocation unit 21 determines the allocation car based on the content prohibited by the prohibition unit 22. The function of the prohibition unit 22 will be described later.

When the allocation unit 21 determines the car 4 to which the landing call is assigned, the group management device 2 transmits the allocation information to the control device 30 that controls the car 4 (S103). For example, when a new landing call is assigned to the car 4A in S102, the allocation information is transmitted from the group management device 2 to the control device 30A.

FIG. 4 is a flowchart showing an operation example of the control device 30. The operation control unit 32 controls the operation of the elevator device 3 by the car 4 (S201). For example, the operation control unit 32A controls the operation by the car 4A. The operation control unit 32B controls the operation by the car 4B.

As described above, the control device 30 receives various information from the group management device 2, the car 4, and other devices. The information input unit 33 inputs these received information to the operation control unit 32. The operation control unit 32 controls the operation including various operations based on the input information from the information input unit 33.

For example, in the control device 30, the landing call is registered based on the landing button information from the operation panel 15. In the control device 30, the car call is registered based on the destination button information from the operation panel 10. In S201, the operation control unit 32 moves the car 4 so that the car 4 sequentially responds to the registered calls. When the car 4 stops at the landing, the operation control unit 32 opens and closes the door 7 so that the user can get on and off the car 4.

Further, each control device 30 performs a process for recording information regarding the operation of the elevator device 3 in time series. In the following, the information is also referred to as "operation information". For example, operation information is input to the information recording unit 34 from the information input unit 33 (S202). The information recording unit 34 sequentially records the operation information input from the information input unit 33 in the storage unit 31 (S203). As a result, operation information is accumulated in the storage unit 31. For example, the storage unit 31A stores information regarding the operation of Unit A. Information regarding the operation of Unit B is stored in the storage unit 31B.

The operation information includes input information from the information input unit 33 to the operation control unit 32. For example, the input information includes allocation information, door open button information, door close button information, destination button information, switch information, information indicating the position of the door 7, information indicating the position of the car 4, and running of the car 4. Contains information to indicate. The input information may not include a part of the above information. The input information may include other information. The operation information may include a history of operations performed in the operation of S201.

FIG. 5 is a flowchart showing another operation example of the control device 30. The detection unit 35 detects a specific improper operation generated by the operation of S201. Inappropriate operation is preset. As an example, from the viewpoint of safety, an abnormal operation that makes it impossible to continue the operation is set as an inappropriate operation. As another example, an operation that does not hinder the continuation of the operation but causes discomfort to the user may be set as an inappropriate operation.

For example, the detection unit 35 detects the confinement of the user as an inappropriate operation. The detection unit 35 may detect an unintended opening and closing of a door as an inappropriate operation. The detection unit 35 may detect unintended call registration and call cancellation as inappropriate operations. The detection unit 35 may detect a call assignment that is clearly inefficient as an inappropriate operation. The detection unit 35 may detect other operations as inappropriate operations.

In the control device 30, it is determined whether or not the detection unit 35 has detected an inappropriate operation (S301). In the following, a specific example will be described assuming that a specific inappropriate operation has occurred in Unit A. The inappropriate operation generated in Unit A is detected by the detection unit 35A (Yes in S301).

If it is determined to be Yes in S301, the extraction unit 36 extracts the operation information in a specific time zone from the storage unit 31 (S302). This time zone includes the time when the inappropriate operation occurs. As an example, the time zone is set to the time from C seconds before to D seconds after the time when the inappropriate operation occurs. The values of C and D are preset.

The identification unit 37 specifies an information input pattern in which the inappropriate operation is reproduced based on the operation information extracted by the extraction unit 36 (S303). That is, when the detection unit 35 detects an inappropriate operation, the identification unit 37 identifies S303 based on the operation information stored in the storage unit 31. For example, the specific unit 37 analyzes the operation information extracted by the extraction unit 36. The specific unit 37 may use machine learning in this analysis. Based on the analysis result, the specific unit 37 creates an information input pattern in which the type and content of the information to be input and the input timing of the information are defined. In the example shown in the present embodiment, the "information input pattern in which the inappropriate operation is reproduced" may include the "information input pattern in which it is determined that the inappropriate operation is likely to be reproduced". ..

The information input pattern specified by the specific unit 37 is transmitted from the control device 30 to the group management device 2 (S304). Further, the information input pattern specified by the specific unit 37 is transmitted from the control device 30 of the elevator device 3 in which the improper operation has occurred to the control device 30 of the other elevator device 3 in which the improper operation has not occurred. (S304). When an inappropriate operation is detected by the detection unit 35A, the information input pattern specified by the specific unit 37A is transmitted from the control device 30A to the control device 30B.

As shown in FIG. 3, the group management device 2 determines whether or not the information input pattern specified by the specific unit 37 has been received from the control device 30 (S104). If it is determined to be Yes in S104, the specifying unit 23 specifies a call registration pattern in which the inappropriate operation is reproduced, based on the information input pattern specified by the specifying unit 37 (S105). In the example shown in the present embodiment, the "call registration pattern in which the inappropriate operation is reproduced" includes the "call registration pattern in which it is judged that the inappropriate operation is likely to be reproduced". Is also good.

For example, the specific unit 23 identifies the call registration pattern by analyzing the information input pattern specified by the specific unit 37. The specific unit 23 may use machine learning in this analysis. As another example, a pattern for determination may be preset. In such a case, the specific unit 23 determines whether or not the information input pattern specified by the specific unit 37 includes a pattern for determination. The specifying unit 23 specifies the pattern for determination included in the information input pattern as a call registration pattern in which an inappropriate operation is reproduced. Machine learning may be used in setting the pattern for determination.

The prohibition unit 22 prohibits the call registration pattern in each elevator device 3 from being the same as the call registration pattern specified by the specific unit 23. FIG. 6 is a flowchart showing another operation example of the group management device. FIG. 6 shows the process included in S102 of FIG. The process shown in FIG. 6 is performed on each car 4 that is a candidate for the allocation car.

If it is determined to be Yes in S101 of FIG. 3, it is necessary to assign a new call to any of the cars 4. At this time, when the new call is assigned to a certain car 4, the prohibition unit 22 determines whether or not the registration pattern of the call for the car 4 matches the registration pattern of the call specified by the specific unit 23 ( S401).

If it is determined to be Yes in S401, the prohibition unit 22 prohibits assigning the new call to the car 4 (S402). As a result, the car 4 is excluded from the candidates for the allocation car. On the other hand, if No is determined in S401, the prohibition unit 22 does not prohibit the new call from being assigned to the car 4 (S403). As a result, the car 4 is not excluded from the candidates for the allocation car. In S102, the allocation unit 21 determines an allocation car for the new call from the cars 4 that are not excluded from the allocation car candidates.

FIG. 7 is a flowchart showing another operation example of the control device 30. The control device 30 determines whether or not an information input pattern has been received from another control device 30 (S501). For example, the control device 30B determines whether or not the information input pattern specified by the specific unit 37A has been received from the control device 30A. When the detection unit 35A detects an inappropriate operation, the control device 30B receives the information input pattern specified by the specific unit 37A in S303 (Yes in S501).

As described above, the operation control unit 32 controls the operation by the car 4 based on the input information from the information input unit 33. When the determination is Yes in S501, the determination unit 38 determines whether or not the information input pattern from the information input unit 33 to the operation control unit 32 matches the information input pattern received from the other control device 30 in S501. (S502).

If it is determined to be Yes in S502, the adjusting unit 39 adjusts the input timing of the information to the operation control unit 32 (S503). For example, the adjustment unit 39B adjusts the input timing so that the information input timing to the operation control unit 32B does not match the information input timing in the information input pattern specified by the specific unit 37A. As a result, the information is input to the operation control unit 32B at a timing deviated from the information input timing in the information input pattern specified by the specific unit 37A.

In the example shown in the present embodiment, for example, when an inappropriate operation occurs in the A unit, the possibility that the same inappropriate operation occurs in the B unit in which the inappropriate operation does not occur can be reduced.

Inappropriate behavior can occur when certain behaviors are performed under certain circumstances. In addition, improper operation may occur when a specific operation is performed at a specific timing. Improper operation caused by such a cause does not always occur only in Unit A. When Unit A and Unit B are the same model, the same inappropriate operation is likely to occur in both. When Units A and B are installed in the same building, the same inappropriate operation is likely to occur in both units. When Units A and B belong to the same bank, the same inappropriate operation is likely to occur in both units. Further, even when Unit A and Unit B belong to different banks, if the configuration of the equipment of Unit A and the configuration of the equipment of Unit B are similar, the same inappropriate operation is likely to occur in both.

In the example shown in the present embodiment, when a new call is assigned to the car 4B and the call registration pattern for the car 4B matches the call registration pattern specified by the specific unit 23A, the new call unit 22 is new. It is prohibited to assign the call to the car 4B. This prevents the improper operation detected in the A unit from occurring in the B unit.

In the example shown in the present embodiment, the adjustment unit 39B has an operation control unit so that the information input timing to the operation control unit 32B does not match the information input timing in the information input pattern specified by the specific unit 37A. Adjust the input timing of information to 32B. This prevents the improper operation detected in the A unit from occurring in the B unit.

In the present embodiment, a preferred example in which the elevator system 1 includes both the prohibition unit 22 and the adjustment unit 39 has been described. Even if only one of the prohibition unit 22 or the adjustment unit 39 is provided in the elevator system 1, a certain effect can be expected.

In this embodiment, an example in which the car 4 is provided with a destination button has been described. The destination button may be provided on the operation panel 15 of the landing. In such a case, the group management device 2 receives the registration request for the landing destination call from the operation panel 15 as the landing button information.
