Description

Elevator information gathering system

This disclosure relates to an elevator information collection system.

Patent Document 1 discloses an example of an elevator rope monitoring device. The rope monitoring device estimates the portion of the rope where the deformation has occurred, based on the relationship between the pulley and the portion of the rope provided with the collision detection sensor that detects the collision of the rope.

Embodiment 1.
FIG. 1 is a configuration diagram of an elevator according to the first embodiment.

Elevator 1 is applied to buildings. The building has multiple floors. In the building, a hoistway 2 is provided over a plurality of floors. The hoistway 2 is a space that is long in the vertical direction. A landing 3 is provided on each of the plurality of floors. At the landing 3, a landing door (not shown) is provided. The landing door is a door that separates the landing 3 and the hoistway 2.

The elevator 1 includes a hoisting machine 4, a main rope 5, a car 6, a counterweight 7, a car-side fixed pulley 8, a weight-side fixed pulley 9, and a control panel 10.

The hoisting machine 4 is provided, for example, at the upper part or the lower part of the hoistway 2. Alternatively, when the machine room is provided in the building, the hoisting machine 4 may be provided in the machine room. The hoisting machine 4 has a sheave 11 and a motor 12. The sheave 11 of the hoisting machine 4 is connected to the rotating shaft of the motor 12 of the hoisting machine 4. The sheave 11 of the hoisting machine 4 is an example of the pulley of the elevator 1. The motor 12 of the hoisting machine 4 is a device that generates a driving force for rotating the sheave 11 of the hoisting machine 4.

The main rope 5 is wound around the sheave 11 of the hoisting machine 4. The main rope 5 is an example of the rope of the elevator 1. Both ends of the main rope 5 are fixed in the hoistway 2.

In the hoistway 2, the car 6 is suspended by the main rope 5 on one side of the sheave 11 of the hoisting machine 4. In the hoistway 2, the counterweight 7 is suspended by the main rope 5 on the other side of the sheave 11 of the hoist 4. The car 6 is a device that transports a user or the like between a plurality of floors by traveling vertically inside the hoistway 2. The car 6 includes a car door (not shown). The car door is a device that opens and closes so that the user of the elevator 1 can get on and off the car 6 when the car 6 is stopped on any floor. The landing door on the floor where the car 6 is stopped opens and closes in conjunction with the car door. The counterweight 7 is a device that balances the load applied to the sheave 11 of the hoisting machine 4 with the car 6 through the plurality of main ropes 5. The car 6 and the counterweight 7 travel in opposite directions on the hoistway 2 due to the movement of the main rope 5 by the rotation of the sheave 11 of the hoisting machine 4. That is, when the car 6 travels, the main rope 5 moves with respect to the pulley of the elevator 1 such as the sheave 11 of the hoisting machine 4.

The car-side fixed pulley 8 is a pulley on which the main rope 5 is wound between the sheave 11 and the car 6 of the hoisting machine 4. The weight-side constant pulley 9 is a pulley on which the main rope 5 is wound between the sheave 11 and the counterweight 7 of the hoisting machine 4. Each of the car-side fixed pulley 8 and the weight-side fixed pulley 9 is arranged so as not to move in the vertical direction on the hoistway 2. Each of the car-side fixed pulley 8 and the weight-side fixed pulley 9 is an example of the pulley of the elevator 1.

The control panel 10 is a part that controls the operation of the elevator 1. The operation of the elevator 1 includes the operation of the elevator 1 such as the running of the car 6.

The car 6 includes a first car side moving pulley 13a and a second car side moving pulley 13b. Each of the first car side moving pulley 13a and the second car side moving pulley 13b moves in the hoistway 2 in the vertical direction as the car 6 travels. Each of the first car side moving pulley 13a and the second car side moving pulley 13b is provided, for example, at the lower part of the car 6. Each of the first car side moving pulley 13a and the second car side moving pulley 13b is a pulley around which the main rope 5 is wound. Each of the first car side moving pulley 13a and the second car side moving pulley 13b is an example of the pulley of the elevator 1.

The balancing weight 7 includes a weight-side moving pulley 14. The weight-side moving pulley 14 moves in the hoistway 2 in the vertical direction as the counterweight 7 travels. The weight-side moving pulley 14 is provided, for example, on the upper portion of the counterweight 7. The weight-side moving pulley 14 is a pulley around which the main rope 5 is wound. The weight-side moving pulley 14 is an example of the pulley of the elevator 1.

The rope of the elevator 1 is a rope that moves when the car 6 travels. The pulley of the elevator 1 is a pulley around which the rope of the elevator 1 is wound. In this example, the main rope 5, which is an example of the rope of the elevator 1, is a weight-side moving pulley 14, a weight-side fixed pulley 9, a sheave 11 of the hoisting machine 4, a car-side fixed pulley 8, and a first car-side moving pulley 13a. , And the second car side moving pulley 13b are wound in this order.

Here, an abnormality may occur in the rope of elevator 1. The abnormality that occurs in the rope of the elevator 1 is, for example, the breakage of the wire of the rope of the elevator 1. The broken wire may collide with, for example, the stopper of the pulley of the elevator 1. At this time, the torque value of the motor 12 of the hoisting machine 4 may fluctuate due to an increase in resistance due to a collision or the like. Therefore, for example, by monitoring the fluctuation of the torque value of the motor 12 of the hoisting machine 4, an abnormality of the rope of the elevator 1 is detected. The elevator 1 has a plurality of sensitive parts that react to an abnormality in the rope of the elevator 1. The sensation range corresponds to each sensational part. Each sensational portion is a portion that reacts to an abnormality in the rope of the elevator 1 in the corresponding sensational range. The sensitive part is provided for the rope of the elevator. The sensitive portion is, for example, a pulley or a pulley stopper. When the sensitive portion is a pulley having a stopper or a stopper of the pulley, the reaction to the abnormality of the rope is an increase in the resistance of the rope due to the collision of the broken wire with the pulley's stopper. The abnormality generated in the rope of the elevator 1 is detected through a physical quantity such as a resistance or a torque value that changes due to the reaction of the sensitive portion. The sensible range is, for example, a spatial range including a sensible portion corresponding to the sensible range. When the felt portion is a pulley, the felt range is, for example, the range including the portion of the total length of the rope of the elevator 1 that is wound around the pulley. Alternatively, when the sensation portion is a stopper for the pulley, the sensation range includes the portion of the total length of the rope of the elevator 1 that is wound around the pulley and includes the stopper.

On the other hand, when a plurality of felt parts are provided in the elevator 1, when an abnormality of the rope is detected, it is not possible to identify which of the plurality of felt parts has detected the abnormality of the rope. The sensation range of the sensation part that responded to the abnormality corresponds to the part of the rope where the abnormality occurred. Therefore, when the sensitive part that has reacted to the abnormality is not identified, it is necessary to collect information for estimating the part of the rope of the abnormality. Here, the abnormality generated in the rope moves together with the rope. Therefore, other sensitive parts may react to the abnormality depending on the position of the car 6. By associating the position of the car 6 when the abnormality is detected with the part of the rope in each of the feeling ranges of the plurality of feeling parts, it is possible to obtain the information used for estimating the part where the abnormality has occurred. can. That is, by running the car 6 in an appropriate manner, information used for estimating the portion where the abnormality has occurred in the rope is collected. Therefore, the information collecting system 15 is applied to the elevator 1 so that the information for estimating the portion of the rope where the abnormality has occurred can be collected.

FIG. 2 is a configuration diagram of the information collection system 15 according to the first embodiment.

The information collection system 15 includes an operation control unit 16, a storage unit 17, an abnormality detection unit 18, a candidate extraction unit 19, a site estimation unit 20, a notification unit 21, a route calculation unit 22, and a route selection unit 23. And.

The operation control unit 16 is a part that controls the operation of the elevator 1. The operation control unit 16 is provided on, for example, the control panel 10. The operation of the elevator 1 includes, for example, running the car 6, opening and closing the car door, and registering a call.

The storage unit 17 is a portion that stores information of the sensitive unit. In this example, the storage unit 17 stores information on the pulley of the elevator 1. The storage unit 17 is provided in, for example, the control panel 10. Here, the portion of the main rope 5 that falls within the perceived range of each of the plurality of pulleys of the elevator 1 changes depending on the movement of the main rope 5. Further, the car 6 of the elevator 1 travels on the hoistway 2 by the movement of the main rope 5. Therefore, the portion of the main rope 5 corresponding to the plurality of pulleys of the elevator 1 corresponds to the position of the car 6. On the other hand, the number of pulleys or the arrangement of a plurality of pulleys may differ depending on the model of the elevator 1. Therefore, the storage unit 17 stores the relationship between the portion of the main rope 5 and the position of the car 6 in the perceived range of each of the plurality of pulleys of the elevator 1 as the information of the pulleys of the elevator 1. The relationship stored by the storage unit 17 is, for example, a relationship in which the portion of the main rope 5 in the sensation range of the pulley of the elevator 1 is associated with the position of the car 6. The storage unit 17 may store, for example, a table showing the correspondence between the portion of the main rope 5 and the position of the car 6 in the felt range of the pulley of the elevator 1. Alternatively, the storage unit 17 may store information representing, for example, a portion of the main rope 5 in the felt range of the pulley of the elevator 1 as a function of the position of the car 6.

The abnormality detection unit 18 is a portion that detects an abnormality in the rope of the elevator 1 by the reaction of the sensitive unit. In this example, the abnormality detection unit 18 detects the abnormality of the main rope 5 as follows, for example, through the stopper of the pulley of the elevator 1 which is an example of the sensitive unit. The resistance of the main rope 5 increases when the abnormal portion generated in the main rope 5 collides with the stopper. A torque sensor (not shown) detects fluctuations in the torque value of the motor 12 due to an increase in the resistance of the main rope 5. The abnormality detection unit 18 detects an abnormality in the main rope 5 by receiving a detection signal from the torque sensor. The abnormality detection unit 18 is provided, for example, in the motor 12 of the hoisting machine 4. The abnormality detection unit 18 may be provided on the control panel 10. When the abnormality detection unit 18 detects an abnormality, it notifies, for example, the candidate extraction unit 19.

When the abnormality detection unit 18 detects an abnormality, the candidate extraction unit 19 sets a plurality of rope parts of the elevator 1 in each of the feeling ranges of the plurality of feeling parts with respect to the rope parts where the abnormality has occurred. This is the part to be extracted as a candidate for. In this example, the portion of the main rope 5 in the sensation range of the pulley of the elevator 1 is derived based on the position of the car 6 when the abnormality is detected and the relationship memorized by the storage unit 17. The candidate extraction unit 19 is provided on, for example, the control panel 10. The candidate extraction unit 19 outputs the extracted candidate information to, for example, the site estimation unit 20.

The part estimation unit 20 is a part that estimates a part where an abnormality has occurred in the rope of the elevator 1 from the candidates extracted by the candidate extraction unit 19. The site estimation unit 20 is provided on, for example, the control panel 10. When the site estimation unit 20 can estimate the site where the abnormality has occurred, the site estimation unit 20 outputs the estimation result to the notification unit 21. On the other hand, the site estimation unit 20 notifies the route calculation unit 22 when the site where the abnormality has occurred cannot be estimated.

The notification unit 21 is a part that notifies an abnormality or the like that has occurred in the elevator 1. The notification unit 21 notifies, for example, the administrator of the elevator 1 or the information center. The information center is a base for collecting information on the elevator 1. The notification unit 21 is provided on, for example, the control panel 10.

The route calculation unit 22 is a part that calculates an operation route for collecting information used for estimating a part where an abnormality has occurred in the rope of the elevator 1. The driving route is, for example, a route on which the car 6 travels. The driving path is, for example, a sequence of one or more positions where the car 6 stops in the hoistway 2. The position where the car 6 stops in the hoistway 2 is, for example, one of a plurality of floors. The route calculation unit 22 is provided on, for example, the control panel 10. The route calculation unit 22 calculates the operation route when receiving a notification from, for example, the part estimation unit 20. The route calculation unit 22 calculates one or more operation routes based on the candidate information extracted by the candidate extraction unit 19. The route calculation unit 22 outputs the calculated operation route to, for example, the route selection unit 23.

The route selection unit 23 is a part that selects one driving route for actually traveling the car 6 from one or more routes calculated by the route calculation unit 22. The route calculation unit 22 is provided on, for example, the control panel 10. The route selection unit 23 may acquire the candidate information extracted by the candidate extraction unit 19 through, for example, the route calculation unit 22. The route selection unit 23 selects an operation route based on the acquired candidate information and the like. The route selection unit 23 outputs the selected operation route to the operation control unit 16.

Subsequently, an example of extracting candidates by the information collection system 15 will be described with reference to FIGS. 3 and 4.
3 and 4 are diagrams showing an example of extracting candidates for a site where an abnormality has occurred in the information collection system according to the first embodiment.

FIG. 3 shows an example of a candidate extracted when an abnormality is detected for the first time. In this example, no anomaly was detected prior to the situation shown in FIG.
In FIG. 3, the portion where the abnormality occurs in the main rope 5 is indicated by a cross symbol. In FIG. 3, the candidates extracted by the first detection are indicated by solid triangle symbols.

In this example, the weight-side fixed pulley 9 reacts to the abnormality of the main rope 5 for the first time. At this time, the abnormality detection unit 18 detects the abnormality of the main rope 5. The candidate extraction unit 19 selects a plurality of candidates for the main rope 5 in the perceived range of each of the plurality of pulleys in the elevator 1 based on the relationship between the current position of the car 6 and the storage unit 17. Extract as. Here, the plurality of candidates include the portion of the main rope 5 in the felt range of the weight-side fixed pulley 9. On the other hand, since the plurality of candidates include the part of the main rope 5 in the sensitive range of the other pulleys, the part where the abnormality has occurred in the main rope 5 is not estimated at this time. After that, the car 6 continues to run.

FIG. 4 shows an example of a candidate extracted when an abnormality is detected for the second time.
In FIG. 4, the portion of the main rope 5 where the abnormality has occurred is indicated by a cross symbol. In FIG. 4, the candidates extracted by the first detection are indicated by solid triangle symbols. In FIG. 4, the candidates extracted by the second detection are indicated by broken line triangle symbols.

Since the main rope 5 moves when the car 6 travels, the candidate for the part where the abnormality has occurred also moves together with the main rope 5. In addition, the part where the abnormality has occurred also moves together with the main rope 5.

In this example, the weight side moving pulley 14 reacts to the abnormality of the main rope 5 for the second time. At this time, the abnormality detection unit 18 detects the abnormality of the main rope 5. The candidate extraction unit 19 selects a plurality of candidates for the main rope 5 in the perceived range of each of the plurality of pulleys in the elevator 1 based on the relationship between the current position of the car 6 and the storage unit 17. Extract as. Here, the plurality of candidates include the portion of the main rope 5 within the sensitive range of the weight-side moving pulley 14. The plurality of candidates also include the portion of the main rope 5 within the sensitive range of the other pulleys. Here, the portion within the sensation range of the weight-side moving pulley 14 when the abnormality is detected the second time is extracted as a candidate in both the first detection and the second detection. On the other hand, candidates for other parts are extracted as candidates in only one of the first detection and the second detection. Therefore, the portion within the sensitive range of the weight-side moving pulley 14 when the abnormality is detected for the second time is a promising candidate as the portion where the abnormality has occurred.

Subsequently, an example of information collection by the information collection system 15 will be described with reference to FIGS. 5 to 7.
5 to 7 are diagrams showing an example of information collection of the information collection system according to the first embodiment.

FIG. 5 shows an example of a candidate extracted when an abnormality is detected.
In FIG. 5, the extracted candidates are indicated by triangular symbols.

In this example, the user at the platform 3 on the 5th floor is operating the platform call. At this time, the landing call is registered as a call to stop the car 6 on the 5th floor.

In this example, when the car 6 descends and stops on the second floor, the abnormality detection unit 18 detects an abnormality. The candidate extraction unit 19 selects a plurality of candidates for the main rope 5 in the perceived range of each of the plurality of pulleys in the elevator 1 based on the relationship between the current position of the car 6 and the storage unit 17. Extract as.

At this time, the candidate extraction unit 19 calculates the candidate index value for each of the extracted plurality of candidates. The candidate index value is a value indicating the potential as a candidate for the part of the rope where the abnormality has occurred. That is, the candidate with a high candidate index value is likely to be the site of the rope where the abnormality has occurred. In this example, the candidate index value corresponding to the part of the main rope 5 is a score added each time the part is extracted as a candidate. The candidate index value is stored in, for example, the candidate extraction unit 19 in association with the portion of the main rope 5.

Here, the main rope 5 is classified into a plurality of areas based on the frequency of contact with the pulley in the operation of the elevator 1. In FIG. 5, the area of the classified main rope 5 is indicated by hatching. In FIG. 5, for example, the region A3 is the region having the highest frequency of contact with the pulley. Region A2 is a region where the frequency of contact with the pulley is lower than the frequency of region A3. Region A1 is a region where the frequency of contact with the pulley is lower than the frequency of region A2. The possibility that an abnormality occurs in the main rope 5 increases depending on the frequency of contact with the pulley. Therefore, the region A3 is a region in which an abnormality is more likely to occur than the region A2. Information on classification according to the region of the main rope 5 is stored in, for example, a storage unit 17.

In this example, the candidate extraction unit 19 calculates the candidate index value as follows based on the area of the classified main rope 5. The candidate extraction unit 19 adds a value set based on the region to the score of the candidate index value for each of the plurality of extracted candidates. The value added to the score of the candidate extracted from the area A3 is larger than the value added to the score of the candidate extracted from the area A2. The value added to the score of the candidate extracted from the area A2 is larger than the value added to the score of the candidate extracted from the area A1. The candidate extraction unit 19 may reduce the candidate index value with respect to the portion that was not extracted as a candidate when the abnormality was detected. The candidate extraction unit 19 outputs the information of the candidates extracted in this way to the site estimation unit 20. Although the method of dividing the main rope 5 into the area A1 to the area A3 and adding a different score for each area to the candidate index value is described as an example, the method of calculating the candidate index value is not limited to this. The candidate index value may be calculated by a method of adding the same score regardless of the region. As a result, the candidate index value of the region of the main rope 5 extracted as the most candidate can be set to the highest value.

The part estimation unit 20 narrows down the part of the main rope 5 in which the abnormality has occurred from the information extracted by the candidate extraction unit 19. The site estimation unit 20 estimates that, for example, when there is a candidate whose candidate index value is higher than a preset threshold value, the candidate is a site where an abnormality has occurred. For example, when there is no candidate whose candidate index value is higher than the threshold value, the site estimation unit 20 cannot estimate the site where the abnormality has occurred. When there are a plurality of candidates whose candidate index values are higher than the threshold value, the site estimation unit 20 may estimate all the sites of the plurality of candidates as sites where an abnormality has occurred. Alternatively, when there are a plurality of candidates whose candidate index values are higher than the threshold value, the site estimation unit 20 may estimate the candidate having the highest candidate index value as the site where the abnormality has occurred. Alternatively, when there are a plurality of candidates whose candidate index values are higher than the threshold value, the site estimation unit 20 may not be able to estimate the site where the abnormality has occurred.

When the part estimation unit 20 can estimate the part where the abnormality has occurred, the notification unit 21 receives the estimation result output from the part estimation unit 20. The estimation result includes, for example, information that an abnormality has occurred and the site where the abnormality has occurred. The notification unit 21 notifies the received estimation result. The elevator 1 may continue normal operation even after the notification unit 21 notifies.

On the other hand, when the site estimation unit 20 cannot estimate the site where the abnormality has occurred, the route calculation unit 22 receives a notification from the site estimation unit 20. Upon receiving the notification, the route calculation unit 22 lists possible operation routes from the current position of the car 6, for example. At this time, the route calculation unit 22 may exclude an operation route in which the mileage of the car 6 is longer than a preset threshold value. The route calculation unit 22 calculates one or more driving routes in which at least one of the plurality of candidates passes through at least one of the feeling ranges of the plurality of pulleys among the listed driving routes. The route calculation unit 22 outputs one or more calculated operation routes to the route selection unit 23. Although the case where the route calculation unit 22 calculates the operation route when the part estimation unit 20 cannot estimate the part where the abnormality has occurred is described as an example, the route calculation unit 22 calculates the operation route. Is not limited to this time. For example, the route calculation unit 22 calculates the operation route by the same processing so that when the part estimation unit 20 can estimate the part where the abnormality has occurred, it can confirm whether the estimation result of the part estimation unit 20 is correct. And output etc. may be performed.

The route selection unit 23 selects one operation route for actually traveling the car 6 from one or more operation routes input from the route calculation unit 22.

FIG. 6 shows an example of an operation route selected by the route selection unit 23.
In FIG. 6, the candidates extracted when the car 6 is in the position of FIG. 5 are indicated by triangular symbols.

The route selection unit 23 selects an operation route based on, for example, registered call information. The route selection unit 23 acquires call information from, for example, an operation control unit 16. In this example, a landing call for stopping the car 6 is registered on the 5th floor. At this time, the route selection unit 23 selects, for example, an operation route for stopping the car 6 on the 5th floor. The route selection unit 23 selects, for example, an operation route for raising the car 6 on the second floor and stopping it on the fifth floor. The route selection unit 23 outputs the information of the selected operation route to the operation control unit 16.

The operation control unit 16 drives the car 6 according to the input operation route.

In the driving path selected by the route selection unit 23, the car 6 is raised as a candidate part that is within the sensitive range of the first car side moving pulley 13a in the detection of the abnormality when the car 6 is at the position shown in FIG. Then, it passes through the sensation range of the fixed pulley 8 on the car side before reaching the 5th floor. When there is an abnormality in the candidate site, the abnormality can be detected while the car 6 travels on the driving route selected by the route selection unit 23. When the abnormality is detected, for example, the candidate index value is updated in the candidate extraction unit 19. In this way, information used for estimating the site where the abnormality has occurred is collected. In the selected driving route, other candidates may pass through the sensitive range of other pulleys at different timings. In this example, the candidate portion that was within the perceived range of the weight-side fixed pulley 9 in the detection of the abnormality when the car 6 was in the position of FIG. 5 was the weight-side moving pulley 14 before reaching the situation of FIG. It passes through the sensation range.

If a car call is registered by a user in the car 6, the route selection unit 23 may select an operation route for stopping the car 6 on the floor specified in the car call. good. For example, when a car call for designating the 4th floor is registered, the route selection unit 23 may select an operation route in which the car 6 on the 2nd floor is raised and stopped in the order of the 4th floor and the 5th floor. ..

Here, the 4th or 5th floor, which is the floor where the car 6 is stopped by the registered call, is above the 2nd floor, which is the floor where the car 6 is currently located. Therefore, the ascending of the car 6 is a traveling in a direction approaching the floor. In the example shown in FIG. 6, the route selection unit 23 selects a driving route that does not allow the car 6 to travel in a direction away from the floor.

In FIG. 7, another example of the operation route selected by the route selection unit 23 is shown.
In FIG. 7, the candidates extracted when the car 6 is in the position of FIG. 5 are indicated by triangular symbols. In the situation of FIG. 7, the call is not registered.

The route selection unit 23 may select an operation route based on the candidate index value. At this time, the route selection unit 23 acquires information on the candidate index value from, for example, the candidate extraction unit 19. The route selection unit 23 specifies, for example, one candidate having the highest candidate index value. The route selection unit 23 preferentially selects a driving route having a shorter mileage of the car 6 until the designated candidate passes through the sensitive range of any of the pulleys.

In this example, for example, it is assumed that the candidate within the felt range of the first car side pulley 13a in the detection of the abnormality when the car 6 is in the position of FIG. 5 is the candidate having the highest candidate index value. At this time, the route selection unit 23 designates the candidate. The route selection unit 23 calculates the mileage of the car 6 until the candidate portion passes through the sensitive range for each of the plurality of pulleys. The driving route having the shortest mileage of the car 6 is a driving route in which the candidate portion passes through the felt range of the second car side pulley 13b by lowering the car 6 as shown in FIG. Therefore, the route selection unit 23 preferentially selects the operation route. The route selection unit 23 selects the operation route when it is not affected by other selection conditions or operational restrictions, for example.

When the car 6 travels on the driving route selected in this way, the information used for estimating the abnormal part is collected. Based on the collected information, the site estimation unit 20 estimates the site where the abnormality has occurred.

Subsequently, an example of the operation of the information collection system 15 will be described with reference to FIG.
FIG. 8 is a flowchart showing an example of the operation of the information collection system according to the first embodiment.

In step S1, when the abnormality detecting unit 18 detects an abnormality in the main rope 5, the operation of the information collecting system 15 proceeds to step S2. On the other hand, when the abnormality detecting unit 18 does not detect the abnormality of the main rope 5, the operation of the information collecting system 15 proceeds to step S1 again.

In step S2, the candidate extraction unit 19 extracts candidates for the portion of the main rope 5 where the abnormality has occurred. After that, the operation of the information collecting system 15 proceeds to step S3.

In step S3, the part estimation unit 20 narrows down the candidates for the part of the main rope 5 in which the abnormality has occurred. After that, the operation of the information collecting system 15 proceeds to step S4.

In step S4, when the part estimation unit 20 can estimate the part of the main rope 5 where the abnormality has occurred, the operation of the information collecting system 15 proceeds to step S5. On the other hand, when the part estimation unit 20 cannot estimate the part of the main rope 5 where the abnormality has occurred, the operation of the information collecting system 15 proceeds to step S6.

In step S5, the notification unit 21 notifies the estimation result by the site estimation unit 20. After that, the operation of the information collection system 15 ends.

In step S6, the route calculation unit 22 calculates one or more driving routes in which at least one of the plurality of candidates passes through at least one of the feeling ranges of the plurality of pulleys. After that, the operation of the information collecting system 15 proceeds to step S7.

In step S7, the route selection unit 23 selects an operation route for traveling the car 6 from one or more operation routes calculated by the route calculation unit 22. The route selection unit 23 outputs the selected operation route to the operation control unit 16. The operation control unit 16 drives the car 6 according to the input operation route. After that, the operation of the information collecting system 15 proceeds to step S1.

As described above, the information collection system 15 according to the first embodiment includes a storage unit 17, a candidate extraction unit 19, and a route calculation unit 22. The storage unit 17 stores the relationship between the rope portion and the position of the car 6 in the sensation range for each of the plurality of sensation parts. Each of the plurality of sensitive parts is provided for the rope of the elevator 1. The rope of the elevator 1 is a rope that moves when the car 6 of the elevator 1 travels. The plurality of sensitive parts react to the abnormality of the rope in each sensitive range. When an abnormality in the rope is detected, the candidate extraction unit 19 extracts a rope portion in each of the sensitive ranges of the plurality of sensitive portions as a plurality of candidates for the rope portion in which the abnormality has occurred. .. The parts of the rope within the sensation range of each of the plurality of sensational portions are derived based on the position of the car 6 and the relationship memorized by the memorizing portion 17. The route calculation unit 22 calculates one or more driving routes in which at least one of the plurality of candidates passes through at least one of the feeling ranges of the plurality of feeling parts.

The operation route calculated by the route calculation unit 22 is an operation route in which the reproducibility of the above detection can be confirmed by passing the abnormal part through the sensation range of the sensation part. Therefore, one or more operation routes calculated by the route calculation unit 22 are operation routes for collecting information used for estimating the portion where the abnormality has occurred in the rope. Therefore, by running the car 6 on any of the driving routes calculated by the route calculation unit 22, information used for estimating the portion where the abnormality has occurred in the rope is collected. When the route calculation unit 22 can calculate only one operation route, the route calculation unit 22 may output the calculated operation route to the operation control unit 16. Further, the route calculation unit 22 outputs to the operation control unit 16 an operation route first calculated as an operation route in which at least one of the plurality of candidates passes through at least one of the feeling ranges of the plurality of feeling units. May be good. Alternatively, the route calculation unit 22 may output the calculated plurality of operation routes to the operation control unit 16. At this time, the operation control unit 16 may select an operation route for actually traveling the car 6 from the plurality of input operation routes.

Further, the information collection system 15 includes a route selection unit 23. The route selection unit 23 selects an operation route for traveling the car 6 from one or more operation routes calculated by the route calculation unit 22, whereby the operation route is based on the selection criteria set in the route selection unit 23. Is automatically selected. Therefore, the information used for estimating the abnormal site is efficiently collected. When the route calculation unit 22 can calculate only one operation route, the route selection unit 23 may select the operation route.

Further, the route selection unit 23 selects an operation route for stopping the car 6 on the floor when a call to stop is registered on any of the plurality of floors. As a result, it is possible to collect information on abnormal candidates while suppressing a decrease in user convenience. Here, an abnormality such as a breakage of a wire generated in a rope may become difficult to detect with the passage of time due to, for example, dropping or deformation of the broken portion. Therefore, when an abnormality is detected, it is preferable that the site of the abnormality is promptly estimated. In the information collection system 15, since the route selection unit 23 balances the response to the user's call registration and the collection of information on the candidate for abnormality, the user does not significantly impair the speed of estimating the abnormal part. Elevator 1 is operated according to the request of.

Further, when a call to stop is registered on any of the plurality of floors, the route selection unit 23 operates so that the car 6 does not travel in the direction away from the floor until the car 6 stops on the floor. Select a route. As a result, the car 6 does not pass through the floor that is stopped by the call, so that the convenience of the user is unlikely to decrease. Further, even when the position of the car 6 is displayed to the user, it is unlikely to cause discomfort to the user.

Further, the candidate extraction unit 19 calculates the candidate index value for each of the plurality of candidates. The candidate index value is a value indicating the potential as a candidate for the part of the rope where the abnormality has occurred. The route selection unit 23 selects an operation route based on the candidate index value. As a result, the route selection unit 23 can select an operation route that can confirm the reproducibility of more promising candidates. Therefore, information is collected so that the candidates can be narrowed down more efficiently.

Further, the candidate extraction unit 19 calculates a candidate index value according to the region of each of the plurality of candidates for each of the plurality of candidates extracted when an abnormality of the rope is detected. The likelihood of anomalies may vary depending on the area of the rope. In this case, information is collected so that candidates can be narrowed down more efficiently based on known information about the possibility of anomalies occurring.

Also, a candidate is specified from a plurality of candidates based on the candidate index value. The route selection unit 23 preferentially selects a driving route in which the mileage of the car 6 until the designated candidate passes through one of the feeling ranges of the plurality of feeling parts is shorter. As a result, the route selection unit 23 can select an operation route that can confirm the reproducibility of more promising candidates more quickly. Therefore, information is collected so that the candidates can be narrowed down more efficiently. The route selection unit 23 does not have to specify the candidate. For example, the site estimation unit 20 outputs a notification including the designation of the candidate to the route selection unit 23 or the like when a promising candidate can be specified, although the site estimation unit 20 does not estimate the abnormal site in the narrowing down of the candidates. You may.

Note that the route selection unit 23 may select an operation route for traveling the car 6 in a direction away from the floor when a call to stop is registered on any of the plurality of floors. At this time, the selected operation route is, for example, after the car 6 has passed through the floor without stopping, the floor difference from the floor is returned to the floor within a preset number of floors. This is an operation route or the like in which the car 6 stops on the floor. The preset number of floors is, for example, the first floor.

As a more specific example, a case where a landing call for stopping the car 6 on the 4th floor is registered when the car 6 is on the 3rd floor will be described. At this time, the route selected by the route selection unit 23 is, for example, raising the car 6 on the 3rd floor and stopping it on the 5th floor, lowering the car 6 on the 5th floor without opening and closing the car door, and stopping on the 4th floor. It is a driving route to be made to. For example, a driving route in which a candidate with a high candidate index value passes through the sensitive range of any of the pulleys is a driving route that lowers the car 6 from the 3rd floor to the 1st floor, or raises the car 6 from the 3rd floor to the 5th floor. It is assumed to be one of the driving routes. In this case, it is assumed that the user's landing call is for getting off from the 4th floor to the 3rd floor. In such a case, the route selection unit 23 selects the driving route for traveling the car 6 in the order of the 3rd floor to the 5th floor and the 4th floor, so that the user's convenience is not significantly impaired and the abnormal portion is present. It is possible to collect information promptly for the estimation of. In this way, the route selection unit 23 can select an operation route that balances the convenience of the user and the prompt information collection according to the situation of the elevator 1.

Further, the route selection unit 23 may calculate a route index value for each of the calculated one or more operation routes. The route index value is a value representing the characteristics of the driving route. The route selection unit 23 selects an operation route based on the route index value. The route selection unit 23 may calculate, for example, a predicted value of the waiting time of the user of the elevator 1 when one of the calculated driving routes is driven into the car 6 as a route index value of the driving route. At this time, the route selection unit 23 preferentially selects an operation route having a smaller route index value. As a result, the driving route is automatically selected according to the selection criteria based on the characteristics of the driving route. At this time, for example, by setting the characteristic of the driving route that reflects the convenience of the user as the route index value, the driving route that suppresses the deterioration of the convenience of the user is automatically selected. The predicted value of the waiting time of the user is calculated based on, for example, a registered call. Further, when there are a plurality of users, the predicted value of the waiting time of the users may be an average value, a total value, a maximum value, or the like for the plurality of users. The route index value may be an index that can be calculated according to the mileage of the car 6 or the driving route such as energy consumption. The route index value may be a value calculated by combining a plurality of indexes.

Further, the candidate extraction unit 19 may associate information on the traveling direction of the car 6 when the candidate is extracted with each of the plurality of candidates. At this time, the route selection unit 23 selects the driving route based on the travel direction information associated with each of the plurality of candidates. For example, when an abnormality is detected while the car 6 is raised, the candidate extraction unit 19 may preferentially select an operation route for raising the car 6. The susceptibility of the sensitive portion to the abnormality of the rope may differ depending on the traveling direction of the car 6, for example, depending on the direction in which the broken wire is deformed. Even in such a case, the route selection unit 23 can select an operation route that makes it easier to confirm the reproducibility of abnormality detection.

Further, the route selection unit 23 may specify a condition for starting the traveling of the car 6 on the selected driving route. The route selection unit 23 may output the operation route to the operation control unit 16 including the designation of the start time as a start condition, for example. For example, when an abnormality is detected in a busy time zone or the like, the route selection unit 23 may specify a start time after the busy time zone. The congestion time zone may be a preset time zone. Alternatively, the route selection unit 23 may specify, for example, that there is no registered call as a start condition.

Further, the route selection unit 23 may select an operation route according to a standard that combines a plurality of selection criteria. For example, the route selection unit 23 calculates a plurality of priorities based on a plurality of selection criteria for each operation route, and selects an operation route according to the total priority obtained from the calculated plurality of priorities. You may. The overall priority is, for example, the sum of a plurality of priorities, a weighted sum, or a maximum value. Alternatively, the route selection unit 23 may switch a plurality of selection criteria according to conditions such as a call registration status or a time zone.

Further, the position where the car 6 stops in the operation route calculated by the route calculation unit 22 may be a position between adjacent floors. At this time, the operation control unit 16 does not open or close the car door when the car 6 stops at a position between the floors. Further, the route selection unit 23 may exclude the driving route in which the car 6 stops at a position between the floors when the user is in the car 6 from the selection target.

Further, a part of the information collection system 15 such as the storage unit 17, the abnormality detection unit 18, the candidate extraction unit 19, the part estimation unit 20, the notification unit 21, the route calculation unit 22, the route selection unit 23, and the operation control unit 16 or All may be installed as a single hardware feature. Alternatively, a part or all of the information collecting system 15 such as the operation control unit 16 may be installed as a function of individual hardware. A part or all of the information collecting system 15 such as the operation control unit 16 may be provided in, for example, a server device provided in a remote place of a building to which the elevator 1 is applied.

Further, the roping of the main rope 5 does not have to be exemplified in FIG. 1 and the like. The roping of the main rope 5 may be, for example, 1: 1 roping. Further, the rope of the elevator 1 does not have to be the main rope 5. The rope of the elevator 1 may be, for example, a balancing rope or a speed governor rope.

Further, the abnormality detection unit 18 may detect an abnormality in the rope regardless of the torque value of the motor 12 of the hoisting machine 4. The abnormality detection unit 18 may be, for example, a portion that detects an abnormality by the sound or vibration of a portion of the rope having an abnormality colliding with a pulley. Further, the sensitive portion that reacts to the abnormality does not have to be the pulley of the elevator 1. The sensitive portion may be, for example, a contact sensor that does not output information that identifies each sensitive portion, a non-contact proximity sensor, or the like.
