Description

[Technical field]

[0001] The present invention relates to an elevator system and an elevator control method, and is suitable for application to, for example, an elevator system that operates an elevator so that a non-smoker and a smoker who has just smoked do not get in the elevator at the same time. [Background technology]

[0002] In recent years, the health effects of smoking have become a problem, and there has been growing interest in passive smoking, especially among non-smokers. Separation of smoking areas has been progressing in offices, and smokers are restricted to smoking only in designated smoking areas. Generally, smoking areas are located away from the work areas of an office, for example, outdoor smoking areas or smoking rooms that lead to the outdoors, and smokers often use elevators to move to the smoking areas. When smokers finish smoking in the smoking areas, they use the elevators to return to their seats. Recently, various measures have been considered to prevent non-smokers from feeling uncomfortable.

[0003] For example, Patent Document 1 describes a method in which an air purifier installed inside an elevator car is kept running at all times, and when a car call is made, the car to be dispatched is determined according to the cleanliness of the air measured by an air cleanliness measuring sensor installed inside the car. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2013-237517 A Summary of the Invention [Problem to be solved by the invention]

[0005] However, the method disclosed in Patent Document 1 does not determine the car allocation taking into consideration the characteristics of the passenger who will board, such as whether or not the passenger is a non-smoker or whether or not the passenger has just smoked. Therefore, there is a possibility that a smoker who has just smoked and a non-smoker may ride in the same car. Therefore, there is a risk that a non-smoker may feel uncomfortable when exposed to the cigarette odor of a smoker who has just smoked in the car. For these reasons, it has not been possible to make it difficult for smokers to cause discomfort to non-smokers in elevators.

[0006] The present invention has been made in consideration of the above points, and aims to propose an elevator system and an elevator control method that can make it less likely that smokers will cause discomfort to non-smokers. [Means for solving the problem]

[0007] In order to solve such problems, the present invention comprises a plurality of cars, a platform odor sensor that is provided at the platform and detects odors at the platform on the floor, and a car allocation determination unit that assigns a specific car from among the plurality of cars in response to a car call on the floor, and the car allocation determination unit assigns the specific car from among the plurality of cars based on a platform odor index which is based on the detection results of the odor at the platform.

[0008] Furthermore, the present invention has a landing odor detection step of detecting odor at the landing on the floor using a landing odor sensor provided at the landing, and a car determination step of an elevator car allocation determination unit of the elevator system allocating a specific car from among the multiple cars in response to a car call on the floor based on a landing odor index which is based on the detection result of the odor at the landing. Effect of the Invention

[0009] According to the present invention, it is possible to realize an elevator system and an elevator control method that can reduce the discomfort felt by smokers to non-smokers. [Brief description of the drawings]

[0011] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

[0012] 1 is a diagram showing an example of the appearance of a landing 11 and a floor common area 17 in an elevator system according to this embodiment. The illustrated example shows a situation in which smokers and non-smokers (hereinafter also referred to as passengers) coexist in an office where each floor can be moved by elevator. In this embodiment, the above-mentioned floors are exemplified by the 8th and 9th floors, and a smoking area 19 is installed on the 9th floor.

[0013] The office has a work area 15, a floor common area 17, and a landing 11. The work area 15 is an area where smokers and non-smokers work. The floor common area 17 is an area on each floor that is shared by smokers and non-smokers and where they can move freely.

[0014] The landing 11 is an area where passengers, including smokers and non-smokers, wait to board an elevator. At the landing 11, an elevator door 8 is provided at a position where the elevator car will stop. A car call device 3 is provided on the side wall of the landing 11. The car call device 3 has a button for requesting an elevator car call. A landing odor sensor 5 is provided at the landing 11 on the floor. The landing odor sensor 5 detects odors at the landing 11 on the floor.

[0015] The floor common area 17 on the 9th floor is provided with a passageway through which smokers and non-smokers pass, as well as a smoking area 19 where smokers are permitted to smoke. The floor common area 17 and the landing 11 are provided with signage 9, for example on a side wall. The signage 9 has the function of notifying nearby smokers and non-smokers by displaying text, images, videos, and outputting sounds, as described below. The function of the signage 9 will be described later.

[0016] A number of TOF (Time Of Flight) sensors 7 are provided on the ceiling of the floor common area 17 along positions where smokers and non-smokers can pass. The TOF sensor 7 has a function of measuring the distance to an object (smoker, non-smoker, etc.) by measuring the time it takes for light emitted from a light source to be reflected by the object and return to the sensor, which is a photodetector. The TOF sensor 7 mainly detects that smokers and non-smokers are passing through the floor common area 17. The TOF sensor 7 includes a TOF sensor 7a provided on the ceiling between the smoking area 19 and the landing 11, and a TOF sensor 7b provided between the office area 15 and the smoking area 19. In this embodiment, when it is not necessary to distinguish between these TOF sensors 7a and 7b, they are referred to as TOF sensors 7. The TOF sensor 7 may be provided at least on a floor where the smoking area 19 is located (here, the 9th floor). In this embodiment, a human sensor may be provided instead of the TOF sensor 7.

[0017] For example, on the 9th floor, when a smoker moves from the smoking area 19 to the landing 11, the TOF sensor 7a installed on the ceiling between the smoking area 19 and the landing 11 detects the smoker passing near the entrance / exit of the smoking area 19 in the floor common area 17. On the other hand, when a smoker moves from the smoking area 19 to the office area 15, the TOF sensor 7b installed on the ceiling between the smoking area 19 and the office area 15 detects the smoker passing through the floor common area 17.

[0018] 2 is a diagram showing an example of the configuration of an elevator car 21 that is raised and lowered by a wire 23. The car 21 is equipped with a weight sensor 25, a temperature sensor 29 inside the car, and a ventilation fan 27.

[0019] The weight sensor 25 is provided at the bottom of the car 21 and measures the weight of the car 21 including the weight of the passengers riding in the car. The car odor sensor 29 is provided in the car 21 and is a sensor that detects odors (cigarette odor is exemplified in this embodiment) inside the car 21. The ventilation fan 27 exhausts air inside the car 21 from inside the car 21 to the outside. Note that the ventilation fan 27 may also be configured to take in air from the outside of the car 21 into the inside of the car 21.

[0020] 3 is a system configuration diagram showing an example of the configuration of an elevator system according to this embodiment. The elevator system includes a group management control device 30, two cars 21a, 21b (21), two car control devices 61a, 61b (61), a car call device 3, a hall odor sensor 5, a TOF sensor 7, and a nudge unit 90. When there is no need to particularly distinguish between the two cars 21a, 21b, they are also referred to as cars 21. When there is no need to particularly distinguish between the two car control devices 61a, 61b, they are also referred to as car control devices 61.

[0021] The two car control devices 61a, 61b (61) correspond to the two cars 21a, 21b (21), respectively. When there is no need to distinguish between the two car control devices 61a, 61b, they are referred to as car control devices 61, whereas when there is no need to distinguish between the two cars 21a, 21b, they are referred to as cars 21. The car control device 61a controls, for example, the lifting and lowering operation of the car 21a and the opening and closing operation of the elevator door 8. The car control device 61b controls, for example, the lifting and lowering operation of the car 21b and the opening and closing operation of the elevator door 8. In this embodiment, the car 21a is the first car, and the car 21b is the second car.

[0022] Cage 21a is equipped with a weight sensor 25a, an in-cab odor sensor 29a, and a ventilation fan 27a. Cage 21b is equipped with a weight sensor 25b, an in-cab odor sensor 29b, and a ventilation fan 27b. The in-cab odor sensors 29a and 29b have the same function as the in-cab odor sensor 29. The weight sensors 25a and 25b have the same function as the weight sensor 25. The ventilation fan 27a has ventilation control switched between ON and OFF for exchanging air between the inside and outside of the car 21a. The ventilation fan 27b has ventilation control switched between ON and OFF for exchanging air between the inside and outside of the car 21b.

[0023] The group management control device 30 collects and manages the pressing status of the car call device 3 on each floor, the pressing status of the floor button inside the car 21, the operating status of each car 21, etc., and determines how to perform lifting and lowering control, etc. for each car 21. In accordance with the determination, the group management control device 30 transmits various instructions regarding lifting and lowering control, etc. to each car control device 61a, 61b.

[0024] The group management control device 30 comprises a platform information calculation unit 31, a platform information management unit 32, a platform car call detection unit 33, a car dispatch determination unit 34, a car information management unit 35, a floor occupancy number acquisition unit 36, and an in-car ventilation fan control unit 37.

[0025] The landing information calculation unit 31 calculates a landing odor index for the landing 11 based on the measurement results by the landing odor sensor 5 of the floor landing 11. The landing odor index indicates how strong a specific odor (in this embodiment, cigarette odor is exemplified) is at the floor landing 11 based on the measurement results by the landing odor sensor 5 of the floor landing 11. Details of the landing odor index will be described later.

[0026] The landing information management unit 32 manages the landing odor index at the landing of the floor calculated by the landing information calculation unit 31. The landing information management unit 32 manages the landing information for each point in time based on the calculation results by the landing information calculation unit 31. This landing information includes floor information, whether or not it is a smoking area floor, the landing odor index, and information on traffic flow. Note that the information on traffic flow indicates the number of smoking vehicles moving from the smoking area 19 to the landing 11 on the floor.

[0027] The hall car call detection unit 33 detects a car call from the car call device 3 in response to an operation on the car call device 3 on each floor. That is, the hall car call detection unit 33 detects a car call output from the car call device 3 when a passenger operates either the up button or the down button of the car call device 3 on each floor, and obtains floor information included in the car call regarding the floor on which the passenger is located and pressed button information indicating that the up button or the down button has been pressed.

[0028] The cage information management unit 35 manages cage information of the cage 21a of the No. 1 car via the cage control device 61a. Here, the cage information of the cage 21a includes information on the weight of the cage 21a measured by the weight sensor 25a and information on the odor in the cage 21a detected by the odor sensor 29 in the cage 21a.

[0029] On the other hand, the car information management unit 35 manages the car information of the car 21b of the No. 2 car via the car control device 61b. Here, the car information of the car 21b includes information on the weight of the car 21b measured by the weight sensor 25b and information on the odor in the car 21b detected by the odor sensor 29b in the car 21b.

[0030] The car allocation determination unit 34 determines a specific car from among the multiple cars 21 in response to a car call on a floor. This car allocation determination unit 34 determines multiple cars 21 as allocation candidates from among the multiple cars 21 in response to a car call on each floor. In addition, the car allocation determination unit 34 allocates a specific car from among the multiple cars based on at least a platform odor index based on the odor detection results of the platform 11. This car allocation determination unit 34 preferably allocates a specific car from among the multiple candidate cars based on a car in-cabin odor index based on the odor detection results in each car 21 and a platform odor index based on the odor detection results of each platform 11.

[0031] The group management control device 30 moves the specific car to the call floor, opens the elevator door 8 when the specific car arrives at the call floor, closes the elevator door 8 after the passenger gets into the car 21, and moves the car 21 to the floor desired by the passenger.

[0032] The floor occupancy count acquisition unit 36 ​​has a function of acquiring the number of smokers and non-smokers in the office area. The floor occupancy count acquisition unit 36 ​​may be, for example, a human sensor provided on the ceiling or the like of the office area 15, or instead (or in addition), the floor occupancy count acquisition unit 36 ​​may acquire the number of smokers and non-smokers expected to be present in the office area 15 at a certain point in time, for example, by subtracting the number of people getting off an elevator from the number of people getting on.

[0033] The car ventilation fan control unit 37 is an example of a ventilation fan control unit, and controls ON / OFF switching of the ventilation fan 27a provided in each car 21a via the car control device 61a. This car ventilation fan control unit 37 controls ON / OFF switching as the operating status of the ventilation fan 27b provided in the car 21b via the car control device 61b. This car ventilation fan control unit 37, details of which will be described later, determines whether or not an index in the car exceeds a first threshold value, and as an example, when the index in the car exceeds the first threshold value, if the ventilation fan 27 is not ON, it turns it ON, and if the ventilation fan 27 is ON, it keeps the ventilation fan 27 ON.

[0034] The nudge unit 90 is an example of a notification unit, and when the odor index in the car 21 (hereinafter also referred to as the "specific car 21") allocated by the car allocation determination unit 34 exceeds a first threshold (for example, when there is a strong cigarette odor) based on the car information of the car information management unit 35, it notifies that a smoker may be riding in the specific car 21. Details of the car information will be described later.

[0035] Furthermore, the nudge unit 90 issues a warning not to board the assigned specific car 21 when the hall odor index of the specific hall 11 that received the car call exceeds a second threshold (for example, when there is a strong cigarette odor) based on the hall information in the hall information management unit 32. Note that, as will be described later, the nudge unit 90 may instead issue a warning not to board the elevator for a certain period of time when the hall odor index of the specific hall 11 exceeds the second threshold.

[0036] The elevator system according to this embodiment is configured as described above, and next, an overview of the elevator control method for this elevator system will be briefly described. The elevator control method according to this embodiment includes a landing odor detection step in which the landing odor sensor 5 provided at the landing 11 is used to detect odor at the landing 11 on the floor, and a car determination step in which the car allocation determination unit 34 allocates a specific car 21 from among multiple cars 21 in response to a car call on the floor, based on a landing odor index based on the landing odor detection result. A more specific description will be given below.

[0037] 4 is a flowchart showing an example of the landing information calculation process by the landing information calculation unit 31. This landing information calculation process is executed by the landing information calculation unit 31 every time the landing information calculation unit 31 receives landing information for all floors, for example, every minute.

[0038] In step S1, the landing information calculation unit 31 calculates the landing odor index for the landing 11 on each floor using formulas (1) and (2). Here, function F (number of people on the floor) is a function that takes the number of people on the floor as an argument, G is the number of people heading from the smoking area to the landing, and SUM (landing odor component concentration) is the sum of the odor components at the landing 11. If not on a smoking floor: Landing area odor index = F(number of people on the floor) * SUM(landing area odor component concentration) (1) If you are on a smoking floor: Landing area odor index = G*F(number of people on the floor)*SUM(landing area odor component concentration) (2) As shown in Figure 5, the function F (number of people on the floor) is a function that increases in a stepped manner as the number of people on the floor increases, when the horizontal axis is the number of people on the floor and the vertical axis is the function F.

[0039] In step S2, the landing information calculation unit 31 judges whether the floor to be calculated in the landing information calculation process is a smoking floor. If the floor is not a smoking floor, the landing information calculation unit 31 records the landing odor index in the landing information management unit 32 (step S3). On the other hand, if the floor is a smoking floor, the landing information calculation unit 31 executes step S4.

[0040] In step S4, the landing information calculation unit 31 counts the number of smokers heading from the smoking area 19 to the landing 11 based on the detection result by the TOF sensor 7a provided in the common area 17 of the floor.

[0041] In step S5, the platform information calculation unit 31 judges whether the number of people is 1 or more. If the platform information calculation unit 31 judges that the number of people is not 1 or more, it executes the above-mentioned step S3, whereas if it judges that the number of people is 1 or more, it executes step S6.

[0042] In step S6, the landing information calculation unit 31 calculates the in-car index for each of the cars 21a and 21b using the formula (3). Here, H indicates the car weight. Odor index in car = H*SUM(occupancy odor component concentration) (3)

[0043] In step S3, the platform information calculation unit 31 records the calculated in-car index in the platform information management unit 32.

[0044] FIG. 6 is a diagram showing an example of the landing information managed by the landing information management unit 32. The landing information includes information on each landing from time t to time t-10, and the landing information at each time, for example, at time t, manages, for each floor, information on whether or not a floor has a smoking area (corresponding to the "smoking area floor" shown in the figure), a landing odor index, and a traffic line. Here, the traffic line indicates the number of smokers moving from the smoking area 19 to the landing 11 on a floor where the smoking area 19 is located. In the example shown in the figure, the traffic line on the ninth floor where the smoking area 19 is located is three people, and indicates that these three people can get on the elevator from the landing 11. Note that the traffic lines on floors where the smoking area 19 does not exist are "not included" because it is impossible for smokers to move from the smoking area 19 to the landing 11.

[0045] Fig. 7 is a diagram showing an example of car information managed by the car information management unit 35. In the illustrated example, for the car 21a of car No. 1 and the car 21b of car No. 2 at time t, the position of the car 21, the moving direction, the moving speed, the stopping floor, the hall call, the car weight, the car odor index, and the past average hall odor index are managed for each car. This past average hall odor index corresponds to the average value of the hall odor index of each hall information at time t to time t-10 shown in Fig. 6.

[0046] Here, the stop floor indicates information about the stop floor that is registered as a floor where the train may stop in the future depending on the operation status of the car call device 3 on each floor. The platform call designates the floor where the car call device 3 is operated. The car weight indicates the total weight of the car 21 including the weight of the passengers. The car interior index is the car interior index written by the platform information calculation unit 31 as described above. The past average platform odor index indicates the average value of the platform odor index for floors that stopped 10 minutes prior to the current time from the platform information from time t to time t-10 managed by the platform information management unit 32.

[0047] 8 is a flowchart showing an example of the procedure of the vehicle allocation determination process. The vehicle allocation determination process is executed by the car allocation determination unit 34. When the car call device 3 at the platform 11 on the floor is operated and a car call output from the car call device 3 is detected by the platform car call detection unit 33, the car allocation determination unit 34 executes the following process.

[0048] First, to give an overview, in this embodiment, the car allocation determination unit 34 determines multiple candidate cars to be allocated from among multiple cars 21 in response to car calls on each floor, calculates a total odor index from the odor index in each of the multiple candidate cars 21 and the average value of past platform odor indexes, and, for example, if the platform odor index of the platform where the car call occurred does not exceed the second threshold (for example, if the cigarette odor is weak), the car 21 with the lower total odor index is allocated as a specific car 21 from among the multiple candidate cars to be allocated, whereas if the platform odor index of the platform where the car call occurred exceeds the second threshold (for example, if the cigarette odor is strong), the car 21 with the higher total odor index is allocated as a specific car 21 from among the multiple candidate cars to be allocated. A specific description will be given below.

[0049] In step S11, the car allocation determination unit 34 judges whether the elevator is crowded. Specifically, the car allocation determination unit 34 judges whether the number of registered stop floors exceeds a predetermined threshold in all the cars 21a, 21b and the weight of the cars 21a, 21b acquired by the weight sensor 25 exceeds a specific threshold.

[0050] If the result in step S11 is negative, the car allocation determination unit 34 determines that the elevator is congested, and allocates the nearest car among the multiple cars 21a, 21b. In this way, it is possible to avoid further congestion caused by executing the elevator control method according to this embodiment when the elevator is congested.

[0051] On the other hand, if the result in step S11 is positive, the car allocation determination unit 34 determines that the elevator is not crowded, and executes step S12. In step S12, the car allocation determination unit 34 selects a car to be allocated that can arrive at the floor where the car call was made within a predetermined time.

[0052] In step S13, the car allocation determination unit 34 judges whether there is a plurality of car candidates for allocation. If it is judged that there is not a plurality of car candidates for allocation, the car allocation determination unit 34 executes step S14. In step S14, the car allocation determination unit 34 judges whether there is one or more car candidates for allocation.

[0053] When there is not one or more candidates for allocation, the car allocation determination unit 34 determines to allocate the nearest car 21 (step S12). On the other hand, when there is one or more candidates for allocation, the car allocation determination unit 34 determines to allocate the one car 21 (step S15).

[0054] On the other hand, if it is determined in step S13 that there are multiple cars to be allocated, the car allocation determination unit 34 executes step S16. In this step S16, the car allocation determination unit 34 calculates a total odor index from the car odor index of the car to be allocated and the average platform odor index in the past by using formula (3). Overall odor index = a * car odor index + b * past average boarding odor index (3) Here, a and b are coefficients determined according to the weighting of the smell inside the car 21 and the smell at the hall 11.

[0055] In step S17, the car allocation determination unit 34 judges whether the odor index of the platform from which the car call was made exceeds a second threshold. If it is judged that the odor index of the platform from which the car call was made exceeds the second threshold, the car allocation determination unit 34 decides to allocate a car with a higher overall odor index among the multiple candidates for allocation (step S18). On the other hand, if it is judged that the odor index of the platform from which the car call was made does not exceed the second threshold, the car allocation determination unit 34 decides to allocate a car with a lower overall odor index among the multiple candidates for allocation (step S19).

[0056] 9 is a flowchart showing an example of a procedure for car ventilation fan control processing. This car ventilation fan control processing is executed by the car ventilation fan control unit 37.

[0057] In step S21, the car ventilation fan control unit 37 determines whether the car index exceeds a first threshold value. If the car index exceeds the first threshold value, the car ventilation fan control unit 37 executes step S22. In this step S22, the car ventilation fan control unit 37 determines whether the ventilation fan 27 is ON.

[0058] The car ventilation fan control unit 37 ends the car ventilation fan control process if the ventilation fan 27 is ON, and turns on the ventilation fan 27 if the ventilation fan 27 is not ON (step S23).

[0059] On the other hand, if the odor index inside the car does not exceed the first threshold in step S21, the car ventilation fan control unit 37 executes step S24. In this step S24, the car ventilation fan control unit 37 determines whether the hall odor index of the hall 11 from which the car call was made exceeds the second threshold.

[0060] When it is determined in step S24 that the hall odor index of the hall 11 from which the car call was made exceeds the second threshold, the car interior ventilation fan control unit 37 executes step S25. In this step S25, the car interior ventilation fan control unit 37 determines whether the ventilation fan 27 is ON or not, and if the ventilation fan 27 is not ON, it turns the ventilation fan 27 ON (step S26), whereas if the ventilation fan 27 is ON, it ends the car interior ventilation fan control process.

[0061] On the other hand, if it is determined in step S24 that the hall odor index of the hall 11 from which the car call was made does not exceed the second threshold value, the car interior ventilation fan control unit 37 executes step S27. In this step S27, the car interior ventilation fan control unit 37 determines whether the ventilation fan 27 is ON or not, and if the ventilation fan 27 is ON, turns the ventilation fan 27 OFF, whereas if the ventilation fan 27 is not ON, the car interior ventilation fan control process is terminated.

[0062] The elevator system of this embodiment comprises a plurality of cars 21, a landing odor sensor 5 that is provided at the landing and detects odors at the landing on the floor, and a car allocation determination unit 34 that assigns a specific car from among the plurality of cars 21 in response to a car call on the floor, and the car allocation determination unit 34 assigns a specific car 21 from among the plurality of cars 21 based on a landing odor index based on the results of odor detection at the landing 11.

[0063] In addition, the elevator control method of the elevator system according to this embodiment includes a landing odor detection step of detecting odor at the landing 11 on a floor using a landing odor sensor 5 provided at the landing 11, and a car determination step of allocating a specific car 21 from among a plurality of cars 21 by the car allocation determination unit 34 in response to a car call on each floor, based on a landing odor index which is based on the detection result of the landing odor.

[0064] In this way, non-smokers are more likely to board the specific car 21 assigned to them by the platform odor index based on the results of the platform odor detection, and it becomes more difficult for non-smokers to board the same specific car 21 as smokers, making it less likely for smokers to cause discomfort to non-smokers.

[0065] The elevator system according to this embodiment includes an odor sensor installed in each car 21 that detects odors inside the car 21, and the car allocation determination unit assigns a specific car 21 from among the multiple cars 21 based on an odor index in the car based on the odor detection results inside each car 21. In this way, non-smokers are more likely to board the specific car 21 that has been assigned based on the odor index in the car based on the odor detection results inside each car 21 and the hall odor index based on the odor detection results at each hall, making it more difficult for non-smokers to board the same specific car 21 as smokers, making it less likely for smokers to cause discomfort to non-smokers.

[0066] The elevator system according to this embodiment includes a landing information calculation unit 31 that calculates a landing odor index for the landing 11 on a floor based on the measurement results from the landing odor sensor 5 at the landing 11, and a landing information management unit 32 that manages the landing odor index for the landing 11 calculated by the landing information calculation unit 31. In this way, it is possible to reliably reduce the opportunities for non-smokers and smokers to board the same car 21 by using an objective index called the landing odor index.

[0067] In this embodiment, the landing odor sensor 5 is provided at the landing on each floor, as an example, and the landing information calculation unit 31 calculates the landing odor index for the landing 11 on each floor using formula (1). Here, F (number of people on the floor) is a function that takes the number of people on the floor as an argument, G is the number of people heading from the smoking area 19 to the landing 11, and SUM (landing odor component concentration) is the sum of the odor components at the landing 11. If not on a smoking floor: Landing area odor index = F(number of people on the floor) * SUM(landing area odor component concentration) (1) If you are on a smoking floor: Landing area odor index = G*F(number of people on the floor)*SUM(landing area odor component concentration) (2)

[0068] In this way, the landing information calculation unit 31 calculates the landing odor index for the landing 11 on each floor, taking into account whether it is a smoking floor or not, so that it can accurately grasp whether there are smokers at the landing 11 on each floor.

[0069] The elevator system according to this embodiment includes a weight sensor 25 that measures the weight of the car 21, and the hall information calculation unit 31 calculates an index within the car based on the formula (3). Odor index in car = Weight of car 21 H * SUM (Odor component concentration at the landing) (3)

[0070] In this way, the cage odor index tends to be higher the more passengers there are in cage 21 or the stronger the cigarette smell at platform 11. Therefore, by using such cage odor index, it is possible to roughly determine whether the probability that a smoker is in cage 21 is high or low.

[0071] In this embodiment, the car allocation determination unit 34 determines multiple candidate cars for allocation from among multiple cars in response to car calls on each floor, calculates an overall odor index from the odor index in each of the multiple candidate cars 21 for allocation and the average value of past platform odor indices, and, for example, if the platform odor index of the platform from which the car call was made does not exceed a second threshold value (for example, if the tobacco odor is weak), assigns the car 21 with the lower overall odor index as a specific car 21 from among the multiple candidate cars for allocation, whereas if the platform odor index of the platform from which the car call was made exceeds the second threshold value (for example, if the tobacco odor is strong), assigns the car 21 with the higher overall odor index as a specific car 21 from among the multiple candidate cars for allocation.

[0072] In this way, the car 21 with the lower overall odor index is assigned as the specific car 21 in which a non-smoker is likely to board, thereby preventing the non-smoker from coming into contact with the tobacco odor emitted by a smoker, and when there is a high possibility that a smoker is present at the boarding area 11, the car 21 with the higher overall odor index is assigned, thereby preventing the smoker from boarding the same car as a non-smoker.

[0073] The elevator system according to this embodiment includes a ventilation fan 27 provided in each car 21, and an in-car ventilation fan control unit 37 that controls the ON / OFF switching of the ventilation fan 27. The in-car ventilation fan control unit 37 determines whether the odor index in the car exceeds a first threshold value, and when the odor index in the car exceeds the first threshold value, turns on the ventilation fan 27 if it is not ON, and keeps the ventilation fan 27 ON if it is ON. In this way, when there is a high possibility that a smoker is present in the car 21, the car 21 is ventilated to eliminate the cigarette odor in the car 21, making it difficult for non-smokers to come into contact with the cigarette odor.

[0074] In this embodiment, when the odor index in the car does not exceed the first threshold, the car ventilation fan control unit 37 judges whether the hall odor index of the specific hall 11 that received the car call exceeds the second threshold, and when the hall odor index of the specific hall 11 exceeds the second threshold, if the ventilation fan 27 installed in the specific hall 21 is not ON, the ventilation fan 27 is turned ON, whereas when the hall odor index of the specific hall 11 does not exceed the second threshold, if the ventilation fan 27 installed in the specific hall 21 is ON, the ventilation fan 27 installed in the specific hall 21 is turned OFF. In this way, when there is a risk that a smoker will get into the specific hall 21, the air in the specific hall 21 can be ventilated in advance, and when there is no risk that a smoker will get into the specific hall 21, the ventilation fan 27 installed in the specific hall 21 can be turned OFF to reduce power consumption.

[0075] In this embodiment, when an index in a specific car 21 assigned by the car allocation determination unit 34 exceeds a first threshold based on the car information of the car information management unit 35, the nudge unit 90 notifies that a smoker may be riding in the specific car 21. In this way, non-smokers can refrain from riding in the specific car 21 in which a smoker may be riding, thereby eliminating the risk of feeling sick from exposure to tobacco odor from a smoker and reducing the opportunity for passive smoking.

[0076] In this embodiment, the nudge unit 90 notifies the user not to board the assigned specific car 21 when the hall odor index of the specific hall 11 that has received the car call exceeds the second threshold (for example, when the cigarette odor is strong) based on the hall information of the hall information management unit 32. In this way, the possibility that the smoker will refrain from boarding the specific car 21 increases, and the risk that the non-smoker will board the specific car 21 at the same time as the smoker is reduced. This eliminates the risk that the non-smoker will be offended by the cigarette odor from the smoker, and reduces the chance of the non-smoker being exposed to passive smoking. In this case, the nudge unit 90 may notify the user not to board any car of the elevator for a certain period of time when the odor index of the specific hall 11 exceeds the second threshold. In this way, the cigarette odor will fade after a certain period of time, so that the risk that the non-smoker will be offended by the cigarette odor from the smoker will be eliminated, and the chance of passive smoking will be reduced.

[0077] Although the present embodiment has been described above, the technical scope of the present invention is not limited to the scope described in the above embodiment. It is clear from the claims that various modifications and improvements to the above embodiment are also included in the technical scope of the present invention.

[0078] In this embodiment, the ventilation fans 27a, 27b of the cars 21a, 21b are switched between ON and OFF for exchanging air between the inside and outside of the cars 21a, 21b, but this is not limiting, and the car ventilation fan control unit 37 may control the strength of the output of the ventilation fans 27a, 27b. For example, the car ventilation fan control unit 37 may perform stepwise ventilation control for exchanging air in the cars 21a, 21b between the ON and a state with a lower or higher output than the ON, or between the OFF and a state in which the output of the ventilation fans 27a, 27b is higher than the OFF in a range less than the ON output, or between a state in which the output of the ventilation fans 27a, 27b is higher than the OFF and a state in which the output of the ventilation fans 27a, 27b is lower than the ON. [Industrial Applicability]
