As shown in FIG. 3, the elevator system 100 of Embodiment 1 is an elevator system 100 in which two elevators 1 A and B are provided in a building with four floors. In addition, the structure of a building is not restricted to this. Each elevator 1 is an elevator 1 that stops at each floor from the 1st floor to the 4th floor of the building. The building is provided with four elevator halls from the first floor to the fourth floor corresponding to each elevator 1, for a total of eight elevator halls. A hall button 2 is provided at each elevator hall.

An imaging device 4 is provided in the car of the elevator. The imaging device 4 is, for example, a camera. The imaging device 4 images the inside of the car. The imaging device 4 is connected to the elevator control device 5 , and image information captured by the imaging device 4 is transmitted to the elevator control device 5 . Note that the imaging device 4 does not need to be installed in the car as long as it can image the state inside the car. may be installed in The imaging device 4 is desirable because it can clearly capture an image of the inside of the car if it is installed in the car.

Next, regarding the configuration of the elevator system 100, the elevator 1 will be described first. The elevator 1 comprises, for example, a car 1a and a counterweight 1b. The car 1a moves up and down in the hoistway. A car 1a and a counterweight 1b are suspended in the hoistway by a main rope 1c. The main rope 1c is wound around the drive sheave 1d of the hoist. The hoisting machine is controlled by an elevator controller 5 . That is, the elevator control device 5 controls movement of the car 1a. The car 1a has a car door. A landing door is provided in the elevator hall where the car 1a stops. The elevator control device 5 opens and closes the car door when the car 1a is stopped at a certain hall. Further, the elevator control device 5 controls the opening and closing of the landing door in conjunction with the opening and closing of the car door. The elevator controller 5 controls the elevator 1 in this way.

A hall button 2 is provided at each elevator hall. A user of the elevator 1 can call the hall of the elevator 1 by operating the hall button 2 . The hall button 2 is connected to a hall controller 3. The hall controller 3 transmits a signal input by operating the hall button 2 to the elevator controller 5, and controls the operation of the elevator 1 in response to the hall call of the elevator 1. control. Although not shown, an in-car button is provided in the car 1a, and the user of the elevator 1 can input a desired floor by operating the in-car button. The elevator control device 5 controls the operation of the elevator 1 in response to the input of the in-car button.

The elevator control device 5 will be described with reference to FIG. The elevator control device 5 includes a control section 6 , a storage section 7 , a determination section 8 and an allocation section 9 . A control unit 6 performs a series of controls related to the operation of the elevator 1 .

The elevator control device 5 receives image information captured by the imaging device 4 . Note that the image information includes moving images as well as still images. The storage unit 7 stores image information captured by the imaging device 4 . Note that the storage unit 7 does not need to be provided in the elevator control device 5, and may be an external storage device or a server that communicates with the elevator control device 5 via an internet line.

The storage unit 7 stores a first image, which is a reference image for determining the presence or absence of dirt in the car 1a. The first image is an image captured by the imaging device 4 when the inside of the car 1a is clean. The first image can be captured by the elevator control device 5 issuing a command to the imaging device 4 at any timing. In addition, the first image is periodically captured by the imaging device 4 when the inside of the car 1a is not dirty, such as after cleaning the wall surface or floor surface inside the car 1a or after replacing the wall or floor member inside the car 1a. may be configured to take an image. Also, the first image may be captured by the imaging device 4 while the elevator is stopped. Also, the first image may be captured by the imaging device 4 when there is no user or no object in the car 1a. The first image is taken by the imaging device 4 when the elevator 1 is stopped and there is no user in the car 1a, in order to accurately determine whether the inside of the car 1a is dirty. preferable. Further, when the imaging device 4 is installed in each car 1a, the imaging device 4 installed in each car 1a captures the first image, and the storage unit 7 stores the first image of each car 1a. make sure to The imaging by the imaging device 4 is the same in other embodiments described below.

The judgment unit 8 has a function of judging whether or not the inside of the car 1a is dirty. The dirt inside the car 1a includes dirt such as solid or liquid adhering to the walls and floor inside the car 1a, as well as abnormalities occurring on the surface inside the car 1a such as scratches and tears on the walls and floor. FIG. 4 shows an example of an image of the inside of the car 1a viewed from the elevator doorway side. FIG. 4a shows an image of the clean condition in the basket 1a. FIG. 4a is an example of a first image. FIG. 4b shows an image of dirt in the basket 1a. FIG. 4b shows a state in which there is a scratch X on the left wall surface inside the car 1a and dirt Y on the floor surface.

The determination unit 8 determines whether or not the inside of the car 1a is dirty based on the image of the inside of the car 1a captured by the imaging device 4 . The image capturing device 4 captures a second image as a comparison image in order to determine whether or not the interior of the car 1a is dirty. The second image is captured by the imaging device 4 after capturing the first image. The second image is captured by the imaging device 4 after, for example, an elevator 1 has completed operation for a call and the user is absent. Alternatively, the second image may be captured by the elevator control device 5 issuing a command to the imaging device 4 when a hall call is made. Also, the second image may be periodically captured by the imaging device 4 . The second image is preferably taken when the elevator 1 is stopped and there is no user in the car 1a in order to accurately determine whether the inside of the car 1a is dirty.

The judgment unit 8 judges the presence or absence of dirt in the car 1a by comparing the reference image and the comparison image. That is, the judgment unit 8 judges whether or not the inside of the car 1a is dirty by comparing the second image captured by the imaging device 4 with the first image. The determination unit 8 receives the second image captured by the imaging device 4 when determining whether or not the interior of the car 1a is dirty. Also, the determination unit 8 reads out the first image stored in the storage unit 7 . The determination unit 8 compares the second image and the first image, and determines the presence or absence of dirt in the car 1a based on the difference value between the two images. That is, if there is a difference value in the comparison between the second image and the first image, the determination unit 8 determines that the car 1a is dirty. If there is no difference between the second image and the first image, the determination unit 8 determines that there is no dirt inside the car 1a. The method for determining whether the interior of the car 1a is soiled by the determination unit 8 is not limited to this. You may make it judge that there is dirt at the point in time.

A threshold value is set in advance, and if the difference value exceeds the threshold value, it is determined that there is dirt inside the car 1a. It may be determined that there is no dirt in the car 1a.

The allocation unit 9 allocates the car 1a when an elevator hall call (hereinafter simply referred to as a hall call) is made. The allocating unit 9 includes an allocated car calculation unit 10 and an allocated car allocation unit 11 . The assigned car calculation unit 10 calculates which car 1a is to be assigned when a hall call is made. The assigned car calculation unit 10 calculates the car 1a that can be dispatched fastest to the hall where the hall call is made in the normal elevator operation control, and determines the car 1a to be allocated.

The allocated car allocation unit 11 issues a car allocation command to the control unit 6 to allocate the car 1a determined by the allocated car calculation unit 10 . The control unit 6 controls the assigned car 1a when receiving the dispatch command from the assigned car dispatching unit 11, and operates the car 1a to the boarding hall where the boarding hall call has been made.

The allocating unit 9 receives the result of the determination made by the determining unit 8 regarding the presence or absence of dirt in the car 1a. The determination result may include not only the presence or absence of stains in the car 1a, but also the difference value information obtained by comparing the first image and the second image. When the determination unit 8 determines that the interior of the car 1a is dirty, the allocation unit 9 allocates the car 1a based on the determination. Specifically, the allocation unit 9 preferentially allocates the cages 1a other than the cages 1a determined to be soiled inside the cages 1a. That is, the allocation unit 9 preferentially allocates the cages 1a other than the cages 1a for which the determination unit 8 has determined that the interior of the cages 1a is dirty. The control unit 6 operates the assigned car 1a to the hall where the hall call was made.

Since the allocating unit 9 allocates the car 1a based on the determination result of the determining unit 8, it can be said that the determining unit 8 determines the priority of allocating the car 1a by determining whether the car 1a is dirty. The functions of the determination unit 8 and allocation unit 9 are the same in other embodiments described below.

As a result, the elevator control device 5 judges the presence or absence of dirt inside the car 1a by the judgment unit 8, and preferentially allocates cars other than the car 1a judged to be dirty. It is possible to reduce the discomfort felt due to dirt on the skin.

Next, operation of the elevator control device 5 will be described with reference to FIG.

FIG. 5 is a flow chart showing the operation of the elevator control device 5 according to the first embodiment. The elevator control device 5 receives the first image, which is the reference image, from the imaging device 4 and stores it in the storage unit 7 (ST101). Note that the first image is captured in advance by the imaging device 4 .

The elevator control device 5 receives the second image captured by the imaging device 4 when the elevator 1 is stopped and there is no user in the car 1a (ST102).

Next, the determination section 8 compares the first image and the second image, and determines whether or not there is dirt in the car 1a based on whether or not there is a difference value (ST103). Here, the determination unit 8 reads out the first image from the storage unit 7 .

Subsequently, the assigning unit 9 receives the judgment result from the judging unit 8, and if the judgment result indicates that the car 1a is dirty (YES in ST104), it allocates a car other than the car 1a that has the dirt (ST105). . The control unit 6 controls the car allocated by the allocation unit 9 and operates the elevator 1 (ST106).

If the result of determination is that there is no dirt inside the car 1a (NO in ST104), the allocation unit 9 allocates a car according to normal elevator operation control (ST107). The control unit 6 controls the car allocated by the allocation unit 9 and operates the elevator 1 (ST108). A series of operations of the elevator control device 5 is completed by the flow described above.

As described above, the elevator control device 5 according to Embodiment 1 is used in an elevator that operates a plurality of cars. and an allocation unit 9 for preferentially allocating cars other than the car 1a judged to be dirty when the judgment unit 8 judges that the inside of the car 1a is dirty. is an elevator control device 5 comprising:

According to such a configuration, the elevator control device 5 determines whether or not the interior of the car 1a is dirty by the determination unit 8, and preferentially assigns cars other than the car 1a that is determined to be dirty. It is possible to reduce the discomfort felt by the person due to the dirt inside the car 1a.

Embodiment 2.
Next, the elevator control device 5 according to Embodiment 2 will be described based on the elevator system 100. FIG. FIG. 6 is a block diagram showing the configuration of elevator system 100 according to the second embodiment. In the following description, the configuration different from that of the first embodiment will be mainly described, and the description of the configuration that is the same as that of the first embodiment will be omitted as appropriate. Elevator system 100 according to the second embodiment differs from elevator system 100 according to the first embodiment in that elevator control device 5 includes contamination evaluation section 12 .

The contamination evaluation unit 12 evaluates the contamination in the car 1a based on the determination result of the determination unit 8. FIG. The contamination evaluation unit 12 exchanges information with each of the determination unit 8 and the allocation unit 9 . The contamination evaluation unit 12 receives from the determination unit 8 the result of the determination as to whether or not the interior of the car 1a is contaminated. Further, the dirt evaluation unit 12 transmits the evaluation result of the dirt inside the car 1a to the allocation unit 9 based on the determination result. The allocation unit 9 allocates the car 1a based on the evaluation result received from the dirt evaluation unit 12 .

Specifically, the contamination evaluation unit 12 evaluates the contamination by comparing a difference value obtained by comparing the first image and the second image included in the determination result with a predetermined evaluation value. When the difference value is less than or equal to the evaluation value, the dirt evaluation unit 12 evaluates the state in the car 1a as being highly evaluated, considering that the state is less dirt. Further, when the difference value exceeds the evaluation value, the dirt evaluation unit 12 evaluates that the state inside the car 1a is low because it is heavily dirtied. It should be noted that a plurality of evaluation values may be set in advance, and the state of dirt may be evaluated in a plurality of stages based on the plurality of evaluation values. For example, a first evaluation value and a second evaluation value larger than the first evaluation value are set, and if the difference value is equal to or less than the first evaluation value, the evaluation is high, and the difference value is higher than the first evaluation value. If the difference value is much less than or equal to the second evaluation value, the evaluation may be moderate, that is, the middle evaluation, and if the difference value is greater than the second evaluation value, the evaluation may be low.

After evaluating the dirt in the car 1 a , the dirt evaluation unit 12 transmits the evaluation result to the allocation unit 9 . The allocation unit 9 calculates which car 1a is to be allocated based on the evaluation result, and allocates the car to be allocated. For example, when allocating from the car 1a judged to be dirty, the allocating unit 9 allocates so as to give priority to the high-evaluation car 1a over the low-evaluation car 1a. That is, the allocating unit 9 preferentially allocates the car 1a with a high evaluation. In other words, it can be said that the dirt evaluation unit 12 determines the priority for allocating the car 1a based on the evaluation result.

In this way, the elevator control device 5 evaluates the dirt inside the car 1a and preferentially allocates the car 1a with a higher rating than the car 1a with a lower rating, thereby further reducing discomfort felt by the user. can be done.

As a modification of the elevator control device 5 of Embodiment 2, the car 1a may be assigned based on whether the car 1a is dirty and the length of time until the car 1a reaches the hall. The allocation unit 9 allocates the car 1a based on the presence or absence of dirt inside the car 1a and the length of time until the car 1a reaches the landing. Further, for example, the allocation unit 9 allocates the car 1a based on the evaluation result of the dirt evaluation unit 12 and the length of time until the car 1a reaches the hall. FIG. 7 shows the time required for the car to arrive at the hall, that is, the arrival time, and the level of priority in the evaluation results evaluated by the dirt evaluation unit 12 . The allocation unit 9 allocates the car 1a based on the priority.

When the arrival time is long, the allocation unit 9 allocates the car 1a so that the priority when the evaluation result is low is equal to the priority of the car 1a with the high evaluation. In other words, the allocation of the low-evaluation car 1a is performed in the same manner as the allocation of the high-evaluation car 1a. Whether the arrival time is long or short can be set in advance. For example, when a user of an elevator starts call registration at a boarding hall and the arrival time of car 1a exceeds 30 seconds, it is defined as a long time. exceeds 30 seconds, the allocation unit 9 allocates the car 1a with the low evaluation so that the priority thereof is equal to the priority of the high evaluation car 1a. This is because, considering the efficiency of the user, it may be desirable to dispatch the car with a higher priority even if the car 1a is dirty.

On the other hand, when the arrival time is short, the priority of the car 1a with the low evaluation result is lower than the priority of the car 1a with the high evaluation result. This is the same as the previous description of the priority set by the dirt evaluation unit 12 .

By doing so, the elevator control device 5 allocates the car 1a based on the evaluation result of the dirt evaluation unit 12 and the length of time until the car 1a reaches the hall. It can be shortened without sacrificing convenience.

Moreover, as shown in FIG. 8, the priority may be set by dividing the evaluation result and the arrival time into three levels. In FIG. 8, the evaluation results are in three stages of high evaluation, medium evaluation, and low evaluation, and if the arrival time is short within 0 seconds to 30 seconds, if it is over 30 seconds to 60 seconds, over 60 seconds , which is three stages for a long time. Note that the evaluation result and the arrival time are not limited to the method described above, and may be divided into three or more stages, or the evaluation result and the arrival time may be divided into different numbers of stages.

If the arrival time is short, i.e., within 0 to 30 seconds, the car 1a is assigned according to the evaluation result of the dirt evaluation unit 12 . That is, the priority of a car 1a with a high evaluation is set high, the priority of a car 1a with a medium evaluation is set at medium, and the priority of a car 1a with a low evaluation is set low. When it is desired to lower the priority of allocating the dirty cage 1a, if the arrival time is short, i.e. within 0 to 30 seconds, the priority of the high-ranking cage 1a is increased, and the priority of the middle-ranking cage is increased. The priority of the car 1a and the low-evaluation car 1a may be lowered, or the car 1a other than the high-evaluation car 1a may not be assigned.

If the arrival time is between more than 30 seconds and less than 60 seconds, the allocation unit 9 gives the car 1a with a medium evaluation a higher priority and gives it the same priority as the car 1a with a high evaluation. Allocate the car 1a so that Further, when the arrival time is longer than 60 seconds, the assigning unit 9 assigns the priority of the car 1a with a medium evaluation and the priority of the car 1a with a low evaluation to a high evaluation. The car 1a is assigned so as to have the same priority as the car 1a that has stopped.

By doing so, the elevator control device 5 allocates the car 1a based on the evaluation result of the dirt evaluation unit 12 and the length of time until the car 1a reaches the hall. While shortening, it is possible to reduce the discomfort felt by the user.

Next, the operation of the elevator control device 5 will be explained using FIG.

FIG. 9 is a flow chart showing the operation of the elevator control device 5 according to the second embodiment. Here, the operations from ST201 to ST204 are the same as the operations from ST101 to ST104 in the first embodiment, so the explanation is omitted. When the determination unit 8 determines that the car 1a is dirty (YES in ST204), the dirt evaluation unit 12 compares the difference value with the evaluation value to evaluate the dirt (ST205).

The allocation unit 9 allocates the car 1a based on the evaluation result of the dirt evaluation unit 12 (ST206). The control unit 6 controls the car allocated by the allocation unit 9 and operates the elevator 1 (ST207).

Further, if the result of determination is that there is no dirt inside the car 1a (NO in ST204), the allocation unit 9 allocates a car according to normal elevator operation control (ST208). The control unit 6 controls the car 1a allocated by the allocation unit 9, and operates the elevator 1 (ST209). A series of operations of the elevator control device 5 is completed by the flow described above.

As described above, the elevator control device 5 according to the second embodiment further includes the dirt evaluation unit 12 that evaluates the dirt inside the car 1a determined by the determination unit 8. The dirt evaluation unit 12 has a predetermined evaluation value and the difference value to evaluate the dirt inside the car 1a, and the allocation unit 9 is the elevator control device 5 that allocates the car 1a based on the evaluation result of the dirt evaluation unit 12. FIG.

According to such a configuration, the elevator control device 5 evaluates the dirt inside the car 1a and preferentially allocates the car 1a with a high evaluation over the car 1a with a low evaluation. It is possible to further reduce the feeling of discomfort due to dirt in the car 1a.

Embodiment 3.
Next, the elevator control device 5 according to Embodiment 3 will be described based on the elevator system 100. FIG. FIG. 10 is a block diagram showing the configuration of elevator system 100 according to the third embodiment. In the following description, configurations different from those in Embodiments 1 and 2 will be mainly described, and descriptions of configurations similar to those in Embodiments 1 and 2 will be omitted as appropriate. Elevator system 100 according to Embodiment 3 differs from elevator system 100 according to Embodiment 1 or 2 in that elevator system 100 includes reader 14 .

The reader 14 is a device that reads the dirt tolerance from a portable medium carried by an elevator user. Portable media are, for example, IC cards and tags. Also, the mobile medium may be a mobile terminal such as a smart phone. The reader 14 is provided at the elevator hall. In addition to the elevator hall, the reading device 14 may be installed in a passage leading to the elevator hall or in a gate through which the user goes to the elevator hall.

The reading device 14 is connected to the elevator control device 5 and transmits the contamination tolerance read from the portable medium to the elevator control device 5 . The dirt tolerance is the tolerance for dirt on the car 1a of the elevator user. The dirt tolerance can be set according to the elevator user. Dirt tolerance is information set for each elevator user, such as "dirt permissible" or "dirt not permissible". Examples of users whose dirt tolerance is “permissible dirt” include a case where a robot uses an elevator and a case where an employee uses a building in which an elevator is installed. On the other hand, a visitor to the building can be considered as an example of a user whose dirt tolerance is "unacceptable".

The elevator control device 5 allocates the car 1 a based on the judgment result made by the judgment unit 8 and the contamination tolerance received from the reading device 14 . When the judgment unit 8 judges that the inside of the cage 1a is dirty, the allocation unit 9 preferentially allocates cages 1a other than the cage 1a concerned. That is, the allocation unit 9 assigns the cage 1a with a lower priority for allocating the cage 1a determined to be dirty and with a higher priority for allocating the cages 1a other than the cage 1a determined to have dirt.

Here, if the dirt tolerance level received from the reading device 14 is "permissible dirt", the elevator control device 5 assigns the priority of the car 1a judged to be dirty to the car 1a judged to be dirty. The car 1a is assigned so as to have the same priority as the other cars 1a.

Further, when the dirt tolerance level received from the reading device 14 is "unacceptable dirt", the elevator control device 5 prohibits allocation of the car 1a determined to be dirty. That is, the allocation unit 9 allocates from the cages 1a other than the cages 1a judged to be soiled.

In this manner, the elevator control device 5 assigns the car 1a according to the dirt tolerance of the elevator user, so that the dirt-unacceptable user does not feel uncomfortable with the dirt on the car 1a. In addition, it is possible to efficiently allocate the car 1a to a user who can tolerate dirt, thereby suppressing a decrease in operation efficiency.

As a modification of the elevator control device 5 of the third embodiment, the contamination evaluation section 12 described in the second embodiment may be provided. The function of the contamination evaluation unit 12 is the same as that of the second embodiment. FIG. 11 is a block diagram showing the configuration of an elevator system 100 including an elevator control device 5 of a modified example.

The elevator control device 5 allocates the car 1a based on the evaluation result evaluated by the dirt evaluation unit 12 and the dirt tolerance received from the reading device 14 . The allocation unit 9 allocates the car 1 a based on the evaluation result evaluated by the dirt evaluation unit 12 and the dirt tolerance received from the reading device 14 .

FIG. 12 shows the evaluation results and the priorities in the dirt tolerance. Here, a case is considered in which the evaluation result of the dirt evaluation unit 12 is a high-evaluation car 1a and a low-evaluation car 1a. As explained in the second embodiment, when the evaluation results are high-evaluation car 1a and low-evaluation car 1a, the priority of high-evaluation car 1a is high, and the priority of low-evaluation car 1a is low. Become. Note that the evaluation results and the degree of contamination tolerance are not limited to the methods described above, and may be divided into different numbers of stages.

Here, the assigning unit 9 assigns the car 1a in consideration of the dirt tolerance. In other words, if the dirt tolerance is "unacceptable", the dirt evaluation unit 12 does not allow the low-evaluation car 1a to be assigned. Further, when the dirt tolerance is "acceptable dirt", the dirt evaluation unit 12 assigns the car 1a with the same priority as that of the car 1a with the high evaluation. In the case where a dirt-permissible user and a dirt-not-permissible user ride together in the car 1a, the car 1a may be assigned according to the dirt-not-permissible condition. In addition, regarding "dirt acceptable", a plurality of stages may be provided to determine the priority.

In this way, since the car 1a is assigned according to the dirt tolerance of the users of the elevators, it is possible to reduce the unpleasantness of the dirt on the car 1a for users who cannot tolerate dirt. In addition, it is possible to efficiently allocate the car 1a to a user who can be dirtied, thereby suppressing a decrease in operation efficiency.

Next, operation of the elevator control device 5 will be described with reference to FIG. 13 .

FIG. 13 is a flow chart showing the operation of the elevator control device 5 according to the third embodiment. Here, the operation from ST301 to ST304 is the same as the operation from ST201 to ST204 of the second embodiment, so the explanation is omitted. If the judgment unit 8 judges that the car 1a is dirty (YES in ST304), the allocation unit 9 allocates the car 1a based on the judgment result made by the judgment unit 8 and the degree of contamination tolerance received from the reading device 14. (ST305).

The control unit 6 controls the car allocated by the allocation unit 9 and operates the elevator 1 (ST306).

Further, if the result of determination is that there is no dirt inside the car 1a (NO in ST304), the allocation unit 9 allocates a car according to normal elevator operation control (ST307). The control unit 6 controls the car 1a allocated by the allocation unit 9, and operates the elevator 1 (ST308).

Assignment of cages 1a is made based on dirt tolerance.

In this way, the elevator control device 5 assigns the car 1a according to the dirt tolerance of the elevator users, so that the users who cannot tolerate dirt feel uncomfortable with the dirt on the car 1a. In addition, it is possible to efficiently allocate the car 1a to a user who can be dirtied, thereby suppressing a decrease in operation efficiency.

Embodiment 4.
Next, the elevator control device 5 according to Embodiment 4 will be described based on the elevator system 100. FIG. FIG. 14 is a block diagram showing the configuration of elevator system 100 according to the fourth embodiment. In the following description, configurations different from those in Embodiments 1 to 3 will mainly be described, and descriptions of configurations similar to those in Embodiments 1 to 3 will be omitted as appropriate. Elevator system 100 according to Embodiment 4 differs from elevator systems 100 according to Embodiments 1 to 3 in that elevator system 100 includes detector 15 .

The detection device 15 is, for example, a camera provided at an elevator hall. The detection device 15 captures an image of the elevator user at the hall. The detection device 15 is connected to the elevator control device 5 , and the detection result detected by the detection device 15 is transmitted to the elevator control device 5 . Note that the detection device 15 may be an odor detection device or the like that detects an odor in an elevator hall or the like, in addition to an imaging device such as a camera. When the detection device 15 is a camera, the detection result is image information including objects that cause stains in the car 1a. be. In any case, if the detection device 15 can obtain a detection result, it need not be installed in the elevator hall. It may be provided near the gate where

The detection device 15 has a function of detecting an object that causes dirt in the car 1a at, for example, an elevator hall. When a user with a bicycle is waiting for an elevator at an elevator hall, the bicycle may cause dirt in the car 1a. In addition to bicycles, pets such as dogs and suitcases carried by users are examples of objects that cause dirt in the cage 1a. If such an object that causes dirt to enter the cage 1a enters the cage 1a, the cage 1a may become dirty, which is not desirable. A camera, which is the detection device 15, detects an object that causes dirt in the car 1a from the captured image.

The detection device 15 judges whether or not there is an object that causes dirt in the car 1a by, for example, capturing an image of a user waiting at an elevator hall. For example, a camera, which is the detection device 15, picks up an image of a user in the hall of the elevator, and performs image processing to detect an object that causes dirt in the car 1a. As an image processing method, a known method such as pattern matching can be used.

The detection device 15 transmits the detection result to the elevator control device 5 when detecting an object that causes dirt in the car 1a. If the detection device 15 is, for example, a camera and determines that the user has a bicycle, the detection result is, for example, "bicycle". The elevator control device 5 allocates the car 1 a based on the determination result of the determination unit 8 and the detection result received from the detection device 15 . In the elevator control device 5, when the determination unit 8 determines that the inside of the car 1a is dirty, the allocation unit 9 preferentially allocates the car 1a other than the car 1a. That is, the allocation unit 9 assigns the cage 1a with a lower priority for allocating the cage 1a determined to be dirty and with a higher priority for allocating the cages 1a other than the cage 1a determined to have dirt.

When an object causing dirt is detected in the car 1a, the elevator control device 5 preferentially allocates the car 1a judged by the judgment unit 8 to have dirt in the car 1a to the user. In other words, the elevator control device 5 gives a higher priority to the car 1a determined to be dirty inside the car 1a, and lowers a priority to the other cars 1a.

In this way, the elevator control device 5 assigns the car 1a based on the judgment result of the judging unit 8 and the detection result received from the detection device 15, so that the inside of the car 1a is dirty. In this way, it is possible to suppress the entry of unwanted objects, and to reduce the occurrence of stains on the car 1a.

Further, the detection device 15 is, for example, an odor detection device. When the detection device 15 detects an odor in the elevator hall, the detection result is "there is an odor". For example, pets such as dogs carried by users and waste owned by users may generate odors. there is a possibility. In addition, there is a possibility that the car 1a is filled with odor when the user himself/herself is drinking alcohol. If the car 1a is full of odor, the user using the car 1a may feel uncomfortable. The elevator control device 5 allocates the car 1 a based on the determination result of the determination unit 8 and the detection result received from the detection device 15 . That is, when the detection device 15 detects odor, the elevator control device 5 gives higher priority to the car 1a determined to be dirty inside the car 1a and lowers priority to other cars 1a.

Further, if the detection device 15 is an odor detection device, it may detect the odor in the car 1a. When the detection device 15 detects the odor inside the car 1a, the elevator control device 5 increases the priority of the car 1a determined to be dirty inside the car 1a, and lowers the priority of the car 1a other than the concerned car. do.

In this manner, the elevator control device 5 determines the priority based on the determination result of the determination unit 8 and the detection result received from the detection device 15, and assigns the car 1a. It is possible to suppress the entry of odor-causing substances into the basket 1a, and to reduce the occurrence of odor in the car 1a that is not soiled. In addition, when odor is detected in the car 1a, the car 1a other than the car 1a in which dirt is generated and the car 1a in which the odor is detected is preferentially assigned, so that the user does not feel uncomfortable due to the odor. can be reduced. As for the detection device 15, it is possible to use both a camera and an odor detection device.
