Description

Technical Field

[0001] This invention relates to elevator systems. Background Technology

[0002] In the group management and control of elevators with multiple cars, there is a known method where users reserve their destination floor before boarding the elevator. Based on this group management and control system, it is possible to perform control based on destination floor information, such as allocating cars to users with the same destination floor, thereby improving the elevator system's transport efficiency.

[0003] Furthermore, for example, Patent Document 1 describes an elevator group management control device that controls the operation of multiple elevators, including a designated elevator with specifications suitable for users with specified attributes such as disabled persons. In this group management control device, elevators are allocated such that the occupancy rate at departure is below a maximum occupancy rate. Moreover, if the user information obtained indicates a user with specified attributes, the group management control device ensures that the maximum occupancy rate of the designated elevator is lower than the normal maximum occupancy rate for a specified period. According to the group management control device described in Patent Document 1, by switching the maximum occupancy rate based on user attributes, both transport capacity and convenience for users with specified attributes such as disabled persons can be simultaneously achieved.

[0005] Patent Document 1: Japanese Patent Application Publication No. 2017-154839 Summary of the Invention

[0006] Furthermore, in recent years, there has been increased attention to the prevention of infectious diseases, leading to requirements for infection control measures within elevator cars. When an infection occurs within the elevator car, considering that the main routes of transmission are droplet or airborne transmission, ensuring sufficient distance between users is one effective control measure. However, if only reducing the risk of infection is prioritized by decreasing the number of passengers in the car, the elevator's transport efficiency will decrease, potentially reducing its serviceability.

[0007] The present invention was made in view of the above-mentioned problems, and provides an improved elevator system that can take measures to suppress the reduction of elevator transport efficiency and reduce the risk of infection.

[0008] The elevator system of the present invention comprises: an acquisition unit that acquires infection risk information of a new user, the new user being a user requesting a new elevator call registration; a weight determination unit that determines a weight corresponding to the infection risk information for each of the multiple cars corresponding to the new elevator call; and an allocation unit that determines the car to be allocated to the new elevator from among the multiple cars based on the weights of each of the multiple cars corresponding to the new elevator call and the weights of the elevator calls that have been allocated to the multiple cars.

[0009] Invention Effects

[0010] According to the present invention, the weight of each elevator car can be determined based on the infection risk information of new users, and the allocation of elevator cars can be determined based on this weight. Therefore, the reduction in elevator transport efficiency can be minimized, and sufficient infection countermeasures can be implemented. Attached Figure Description

Detailed Implementation

[0019] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. Furthermore, in the drawings, identical or equivalent parts are labeled with the same reference numerals, and their descriptions are simplified or omitted.

[0020] Implementation method 1.

[0021] Figure 1 This is a block diagram showing the schematic structure of the group management control device for the elevator system according to Embodiment 1. In this embodiment, the elevator system includes multiple elevators, and the group management control device 1 controls the operation of each elevator. Figure 1 The location of the group management control device 1 is not limited; for example, it can be installed in a building with an elevator.

[0022] The group management control device 1 of this embodiment includes a control unit 11, an interface 12, and a storage unit 13. The interface 12 is communicatively connected to the control unit 11, and the control unit 11 is communicatively connected to the storage unit 13, enabling the transmission and reception of information.

[0023] Interface 12 is located at each floor of the elevator. Interface 12 functions as a reading unit, obtaining the user's information when the user requests a new elevator call registration.

[0024] In addition, in the following explanation, as needed, a new elevator call for this elevator will be referred to as a "new call", and the user requesting registration for a new call will be referred to as a "new user", which will be recorded separately from other elevator calls and other users that have already been registered.

[0025] Interface 12 may include, for example, a verification device for personal authentication, a sensor capable of measuring body temperature, a barcode reader capable of reading one-dimensional or two-dimensional identification codes such as QR codes (registered trademarks), and a camera device capable of measuring body temperature and reading codes.

[0026] The user information read via interface 12 includes the user's infection risk information. Infection risk information is an indicator of the likelihood of the user contracting a specific infectious disease. Here, the specific infectious disease may be, for example, one of the currently prevalent infectious diseases, primarily transmitted through air or droplets, and for which strict infection control measures are expected. The specific infectious disease is appropriately set according to the current situation. Infection risk information varies depending on the type of infectious disease, and the information content is appropriately set along with the infectious disease. Specifically, for example, infection risk information may include vaccination-related information such as the number of vaccinations, the type of vaccine, and the number of days since vaccination; infectious disease risk propensity information indicating the prevalence and transmissibility of the infectious disease; and information related to the user's health status such as the user's current body temperature.

[0027] When the infection risk information is related to vaccination, such as when the user presents a vaccination certificate with an identification code, interface 12 can read the infection risk information. Furthermore, when the infection risk information is related to the user's current health status, such as when the user's body temperature is measured using a camera or similar device, interface 12 can read the infection risk information. Alternatively, interface 12 can also obtain the infection risk information by reading the infection risk information that the user has pre-registered as personal information using a verification device.

[0028] The control unit 11 includes processing circuitry. This processing circuitry can be dedicated hardware, software, or a combination of both. When the processing circuitry is software, it includes a CPU (Central Processing Unit) that executes programs stored in memory. The CPU executes the programs stored in memory to implement the functions of the following units within the control unit 11. When the processing circuitry is hardware, the functions of the following units within the control unit 11 can be implemented by individual processing circuits or centrally by a single processing circuit.

[0029] The control unit 11 includes an acquisition unit 11a, a number of people calculation unit 11b, a position calculation unit 11c, a distance calculation unit 11d, a weight determination unit 11e, and an allocation unit 11f. In addition, the control unit 11 has various other functions, but illustrations of these functions are omitted.

[0030] The acquisition unit 11a acquires information related to the new user read via interface 12. The information acquired by the acquisition unit 11a includes the new user's infection risk information. This infection risk information of the new user acquired by the acquisition unit 11a is input into the population calculation unit 11b.

[0031] The passenger count unit 11b calculates the number of passengers in each car corresponding to the new call based on the infection risk information of the new users. Figure 2 This is a diagram showing an example of the correction coefficients calculated by the headcount calculation unit. (See diagram for example.) Figure 2 As shown, the passenger count calculation unit 11b converts the various information contained in the infection risk information into correction coefficients. Then, it multiplies the predetermined rated passenger capacity of each car by the correction coefficients to calculate the passenger count for each car corresponding to the new call. Furthermore, if a decimal number is generated in the calculation of the passenger count multiplied by the correction coefficients, it is processed according to a preset rule. The preset rule is, for example, "discarding".

[0032] exist Figure 2In the example, the parameters used to calculate the correction coefficient in the infection risk information are the number of vaccinations, the type of vaccine, and the number of days since vaccination. Furthermore, the correction coefficients are set to 1, 0.9, 0.8, and 0.6 for vaccinations of 3, 2, 1, and 0 doses, respectively. Similarly, the correction coefficients are set to 1, 0.9, 0.8, and 0.6 for vaccine types X, Y, Z, and no vaccination. The correction coefficients are also set to 1, 0.9, 0.8, and 0.6 for the number of days since vaccination being 0–90 days, 91–181 days, more than 181 days, and no vaccination. The correction coefficient corresponding to the current new user's infection risk information is the value obtained by multiplying these correction coefficients. Therefore, for example, in the case of a new user's infection risk information showing 2 vaccinations, vaccine type X, and a number of days between 91 and 180, the correction coefficient is 0.9 × 1 × 0.9. The calculated correction factor is multiplied by the specified number of passengers in each car to calculate the number of passengers in each car. For example, if the specified number of passengers in a car is 20, the number of passengers in that car corresponding to the new call elevator is calculated as 20 × 0.9 × 1 × 0.9, and the decimal point is discarded, thus setting the corrected number of passengers to 16.

[0033] The number of passengers in each car corresponding to the newly called elevator, calculated by the passenger count unit 11b, is input into the position calculation unit 11c.

[0034] The position calculation unit 11c calculates the intended riding position for each car based on the number of passengers corresponding to the newly called elevator. The intended riding position is the riding position where the passengers are seated in each car with as much distance between them as possible. Figure 3 This is a diagram illustrating the relationship between the number of passengers and the intended seating positions within the elevator car. For example... Figure 3 As shown, the relationship between the number of passengers and the intended boarding positions is preset for each car and stored in the storage unit 13. The position calculation unit 11c calculates the intended boarding position for each car based on the relationship between the number of passengers and the intended boarding positions stored in the storage unit 13, corresponding to the number of passengers input from the passenger calculation unit 11b. The intended boarding positions calculated for each car are then input to the distance calculation unit 11d.

[0035] The distance calculation unit 11d calculates the distance between users in each elevator car based on their boarding positions. For example, the distance between users is set as the shortest distance between any two possible boarding positions in each elevator car. Specifically, such as... Figure 3As shown, when there are 5 passengers, the shortest distance is from the center to any one of the four corners, and this distance is calculated as the distance between users. The calculated distance between users of each elevator car is input into the weight determination unit 11e.

[0036] The weight determination unit 11e determines the weight of each car corresponding to the new call elevator based on the distance between users of each car. Figure 4 This is a diagram used to illustrate the weights of each car, determined by the weighting unit. Specifically, in Figure 4 In the example, the weight determination unit 11e determines the weight of each elevator number (i.e., each car) corresponding to a new call by the value obtained by dividing the distance between users by the number of passengers. The weights determined by the weight determination unit 11e are registered in the storage unit 13.

[0037] For example, when comparing elevators within the same car, the fewer the number of passengers, the greater the distance between users. Therefore, the weight of each car is relatively large for new users calling for elevators with fewer vaccinations and a longer elapsed period since vaccination, and relatively small for new users calling for elevators with more vaccinations and a shorter elapsed period.

[0038] The weights of each car corresponding to the new call elevator, determined by the weight determination unit 11e, are input to the allocation unit 11f.

[0039] The allocation unit 11f determines the car assigned to the newly called elevator. Specifically, as follows: Figure 4 As shown, the allocation unit 11f reads from the storage unit 13 the weights corresponding to the already allocated elevator calls, i.e., the registered elevator calls for each car, and the currently responding elevator. Then, it determines the weight of each car based on the weights for each allocated elevator call and the weight corresponding to the new elevator call. Here, for example, the maximum value between the weights corresponding to each allocated elevator call and the weight corresponding to the new elevator call is used as the weight of each car.

[0040] The allocation unit 11f further multiplies the current number of calls for each car (i.e., the number of registered calls, the number of calls currently being responded to, and the total number of new calls) by the weight of each car to obtain the multiplication result. This multiplication result can be used as one of the factors in determining the allocation of cars.

[0041] For example, in Figure 4In the example, the number of calls assigned to car A is 6. Adding the 1 new call this time gives the total number of calls for car A. Similarly, the total number of calls for cars B and C is 2 each. Furthermore, the maximum weights for cars A, B, and C are 3, 10, and 50, respectively. Therefore, based on the product of the maximum weight of each car and the total number of calls, car A has 18 (maximum weight 3 × number of calls 6), car B has 20 (maximum weight 10 × number of calls 2), and car C has 100 (maximum weight 50 × number of calls 2). Therefore, allocation unit 11f determines car A, whose multiplication result is the minimum, as the assigned car. However, if factors different from the multiplication result are considered when deciding on the assigned car, and car A is excluded from the candidates for assigned car due to these different factors, for example, car B might be selected as the assigned car.

[0042] Next, a flowchart will be used to explain the control actions of the group management control device 1 in Implementation Method 1. Figure 5 This is a flowchart illustrating an example of a control action performed by the group management control device of Embodiment 1. Figure 5 In the control action, when there is a request for elevator registration from a new user on interface 12, firstly, in step S101, the infection risk information of the new user is obtained through interface 12.

[0043] Next, in step S102, the elevator number N is set to "1". Here, the elevator number N is the number corresponding to each elevator, and it is a value set for all elevators controlled by the group management control device 1 in a consecutive numbering manner.

[0044] Next, in step S103, the number of passengers using elevator number N is calculated. Specifically, a correction coefficient corresponding to the new user is calculated based on the infection risk information of the new user. The calculated correction coefficient is multiplied by the pre-set rated number of passengers for elevator number N, and the value is discarded after the decimal point as needed. This calculation result is set as the number of passengers for elevator number N corresponding to the new user.

[0045] Next, in step S104, the intended passenger positions within the car of machine number N are calculated based on the number of passengers calculated in step S103. Next, in step S105, the distance between users within the car of machine number N is calculated based on the intended passenger positions.

[0046] Next, in step S106, a weight corresponding to the new user is determined for machine number N. Specifically, the value obtained by dividing the distance between users calculated in step S105 by the number of passengers calculated in step S103 is used as the weight corresponding to the new user for machine number N. The determined weight is registered in the storage unit 13.

[0047] Next, in step S107, the car number N is incremented by "1". Next, in step S108, it is determined whether the car number N exceeds the total number of cars controlled by the group management control device, i.e., the number of cars. If it is determined in step S108 that the car number N does not exceed the number of cars, the process returns to step S103. Through the processing in steps S103 to S107, the weight for the new user of the next car (i.e., car N = N+1) is determined.

[0048] If, in step S108, it is determined that elevator number N exceeds the number of elevators, proceed to step S109. In step S109, based on the weights corresponding to the registered and responding calls in each elevator car, the weights determined in step S106, and the number of calls for each elevator car, the assigned car for the new call is determined. Then, the current processing ends.

[0049] As described above, according to Embodiment 1, when new users with a higher risk of infection, such as those with fewer vaccinations and a longer period of time since vaccination, utilize the elevator, the elevator car allocation is determined by setting a larger weight value to minimize the number of passengers in the car and maximize the distance between users. In this way, by controlling the allocation of cars based on infection risk information, the risk of infection within the car can be reduced. On the other hand, when users with a lower expected risk of infection utilize the elevator, the number of passengers in the car can be set to be larger, thereby ensuring the elevator's transport efficiency. Therefore, even in situations where infectious diseases are prevalent and infection control measures are expected, excessive restrictions on the number of passengers can be prevented, thereby suppressing a decrease in elevator transport efficiency.

[0050] In addition, in this embodiment, the following is used Figure 2 The relationship between infectious risk information and correction coefficients is explained, but this is only an example. The relationship between infectious risk information and correction coefficients is appropriately set based on factors that are relevant to the following (e.g., number of vaccinations, type of vaccination, number of days elapsed since vaccination): the specific infectious disease for which countermeasures are expected based on the current epidemic situation, its route of transmission, the degree of infectivity, and the effectiveness of vaccines against the infectious disease.

[0051] Furthermore, this embodiment describes calculating the number of passengers corresponding to a new user by multiplying the predetermined number of passengers in each car by a correction factor. However, the method for calculating the number of passengers is not limited to this. If, based on the infection risk information of a new user, the user is judged to have a high probability of infection, the number of passengers can be calculated in a way that makes the number of passengers less than if the probability of infection is judged to be low. Therefore, for example, it is also possible to pre-set the relationship between infection risk information and correction factor, and determine the number of passengers by subtracting the correction factor corresponding to the infection risk information of the new user from the predetermined number of passengers in each car.

[0052] Furthermore, in this embodiment, the method for calculating the distance between users is described, where the position calculation unit 11c calculates the intended elevator position based on the relationship between the number of passengers and the intended elevator position stored in the storage unit 13, and the distance calculation unit 11d calculates the distance between users based on the intended elevator position. However, the method for calculating the distance between users is not limited to this. For example, the relationship between the number of passengers and the distance between users can be pre-registered in the storage unit 13, and the distance calculation unit 11d can read the distance between users corresponding to the number of passengers based on this relationship. In addition, in this case, when the floor areas of multiple elevator cars are different, the relationship between the number of passengers and the distance between users can be set and registered for each elevator car or each floor area.

[0053] Furthermore, in this embodiment, the method of calculating the number of passengers corresponding to a new call elevator, the imagined boarding location, and the distance between users based on infection risk information, and determining the weight corresponding to the new call elevator accordingly, is explained. This allows for determining an appropriate weight for the new call elevator based on the likelihood of infection from a new user. However, the method for determining the weight is not limited to this; for example, the relationship between infection risk information and weight can be directly defined and stored in the storage unit 13. Therefore, the group management control device 1 can determine the weight corresponding to the new call elevator based on the infection risk information of the new user stored in the storage unit 13.

[0054] Implementation method 2.

[0055] The group management control device 1 of Embodiment 2 is the same as the group management control device 1 described in Embodiment 1, except that the information obtained by the acquisition unit 11a and the information stored in the storage unit 13 are different. Specifically, in the group management control device 1 of Embodiment 2, the storage unit 13 stores user information of each user using the elevator and infection risk information associated with each user information.

[0056] After obtaining information such as a user ID that can identify a new user from the interface 12 and authenticating the user based on the user information stored in the storage unit 13, the acquisition unit 11a obtains the user's infection risk information from the infection risk information associated with the user information.

[0057] Figure 6 This is a flowchart illustrating an example of a control action performed by the group management control device of Embodiment 2. Figure 6 The control action, besides replacing step S101 and having the processing of steps S110 and S111, is similar to... Figure 5 The control actions are the same.

[0058] exist Figure 6 In the process, when there is a request for elevator registration from a new user on interface 12, firstly, in step S110, the obtaining unit 11a obtains user information from interface 12 that can identify the new user.

[0059] Next, in step S111, infection risk information corresponding to the user information of the new user obtained in step S110 is obtained from infection risk information associated with user information stored in storage unit 13.

[0060] Then, the infection risk information obtained in step S110 is used to perform... Figure 5 The processing steps S102 to S109 determine the allocation of the car.

[0061] As explained above, the group management control device according to Embodiment 2, like the group management control device 1 of Embodiment 1, can suppress the decrease in elevator transport efficiency and implement infection control measures. Furthermore, the group management control device according to Embodiment 2 simplifies the interface 12 by pre-registering the infection risk information of each user in accordance with user information, for example, eliminating the need for equipment such as temperature measurement devices and cameras for reading identification codes. Moreover, by pre-registering the information, the allocation control of the elevator cars can be smoothly advanced.

[0062] Furthermore, in Embodiment 1, the case where the acquisition unit 11a obtains the user's infection risk information using the interface 12 was described, and in Embodiment 2, the case where the infection risk information stored in the storage unit 13 is read based on the user information obtained by the acquisition unit 11a was described. However, the method for obtaining infection risk information is not limited to either method, and both methods can be used to obtain infection risk information.

[0063] For example, it could be configured such that each user's infection risk information is obtained using interface 12 each time, while information without individual differences is obtained from storage unit 13. Information without individual differences could include, for example, infection risk propensity information indicating the prevalence of infectious diseases. By pre-storing such information, which does not need to be obtained each time, in storage unit 13, unnecessary communication between devices can be suppressed.

[0064] Furthermore, for example, information that can be pre-registered, such as the number of vaccinations, type of vaccination, and vaccination date, can be pre-registered in the storage unit 13. This information can then be read from the storage unit 13, and the interface 12 can be used to obtain information such as the user's body temperature when using the elevator. This information can then be used as infection risk information. As a result, elevator car allocation can be appropriately performed based on more infection risk information, and the amount of information required during use can be reduced, thereby suppressing unnecessary communication and smoothly executing elevator car allocation.

[0065] The preferred embodiments have been described in detail above, but are not limited to the embodiments described above. Various modifications and substitutions can be made to the embodiments described above without departing from the scope of the claims.
