To provide an elevator group control system capable of performing operation while avoiding riding together with a user who is suspicious of being infected, and preventing infection in a car.SOLUTION: An elevator group control system according to one embodiment comprises body temperature detection means, share riding determination means, and allocation control means. The body temperature detection means detects a body temperature of a user who has registered a destination call through a boarding destination floor registration device. When the body temperature of the user is a predetermined value or higher, the share riding determination means determines, from among cars, a car to be used for share riding with a user whose body temperature is lower than the predetermined value on the basis of a boarding section of the user obtained from the information of the destination call and boarding sections of users obtained from information of the currently-registered destination calls. The allocation control means excludes the car determined by the share riding determination means from an allocation object, and decides, from among the cars, the car to which the destination call is allocated.SELECTED DRAWING: Figure 1

Description

[Technical field]

[0001] An embodiment of the present invention relates to an elevator group control system. [Background technology]

[0002] In recent years, the route of infection for viruses and other epidemics has been said to be airborne infection in enclosed spaces, and ventilation is one of the infection prevention measures. Although ventilation fans are generally installed inside elevator cars, it takes a certain amount of time for the air inside the car to be replaced.

[0003] However, in a normal elevator, when a user gets off, other users may get on at the same time, and the user may not always be in a car that is well ventilated. In this case, if a user with a high body temperature (a user suspected of being infected) is in the same car, the risk of other users becoming infected increases.

[0005] Therefore, the problem that the present invention aims to solve is to provide an elevator group management system that can operate elevators while avoiding passengers who are suspected of being infected, thereby preventing infection inside the elevator car. [Means for solving the problem]

[0006] An elevator group management system according to one embodiment includes a hall destination floor registration device installed at a hall, and causes the most suitable car from among a plurality of cars to respond to the hall based on a destination call registered by the hall destination floor registration device.

[0007] The elevator group management system includes a body temperature detection means, a carpooling determination means, and an allocation control means. The body temperature detection means detects the body temperature of a user who has registered a destination call through a landing destination floor registration device. When the body temperature of the user is equal to or higher than a certain value, the carpooling determination means determines which car among the cars will share a ride with a user who has a body temperature below the certain value, based on the user's boarding section obtained from the destination call information and each user's boarding section obtained from the currently registered destination call information. The allocation control means excludes the car determined by the carpooling determination means from the allocation targets, and determines which car to allocate the destination call to from among the cars. When a new destination call is registered, the allocation control means allocates to an elevator car including an elevator in which a user with a body temperature above the certain value has been riding, and when the new destination call is allocated to an elevator in which a user with a body temperature above the certain value has been riding, the allocation control means makes the elevator wait with its doors closed until ventilation for a certain period of time is completed at the registered floor of the new destination call.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] Hereinafter, an embodiment will be described with reference to the drawings. In addition, the disclosure is merely an example, and the invention is not limited to the contents described in the following embodiments. Modifications that a person skilled in the art can easily conceive are naturally included in the scope of the disclosure. In order to make the explanation clearer, the size, shape, etc. of each part may be changed from the actual embodiment and shown diagrammatically. In multiple drawings, corresponding elements may be given the same reference numerals, and detailed explanations may be omitted.

[0010] Fig. 1 is a block diagram showing the configuration of an elevator group management system according to one embodiment, in which a configuration in which multiple elevators are group-managed is shown. Note that "elevator" here basically means "car." In the example of Fig. 1, a configuration in which three elevators (cars) indicated as A, B, and C are group-managed is shown, but a configuration in which more elevators are group-managed is also possible.

[0011] In the figure, 11a to 11c are elevator control devices (also called cage control devices), and 12a to 12c are cars. The elevator control device 11a controls the operation of the cage 12a of car A. Specifically, the elevator control device 11a controls a motor (hoist) (not shown) for raising and lowering the cage 12a, and controls the opening and closing of the doors. The same is true for the elevator control device 11b of car B and the elevator control device 11c of car C. These elevator control devices 11a to 11c are composed of computers equipped with a CPU, ROM, RAM, etc.

[0012] The cars 12a to 12c are raised and lowered in the elevator shaft by the drive of a motor (hoist). Ventilation devices 13a to 13c are installed in the interiors of the cars 12a to 12c. The ventilation device 13a has a mechanism for replacing the air in the car 12a by driving a fan (not shown). The same applies to the ventilation devices 13b and 13c.

[0013] At the landing of each floor, a landing destination floor registration device 14 for registering destination calls is installed. A temperature measuring device 15 is installed in the landing destination floor registration device 14. The temperature measuring device 15 has a function of non-contactly detecting the body temperature of a user who has registered a destination call through the landing destination floor registration device 14, using infrared rays or the like. The information on the user's body temperature detected by this temperature measuring device 15 is transmitted to the group management control device 20 together with the destination call information of that user. The destination call includes information on the departure floor (call registration floor) and the user's destination floor.

[0014] The group management control device 20 is a device for group management control of the operation of each elevator car, and is configured by a computer equipped with a CPU, ROM, RAM, etc., similar to the elevator control devices 11a to 11c. In this embodiment, the group management control device 20 is equipped with a call storage unit 21, a car-sharing determination unit 22, an allocation control unit 23, a ventilation determination unit 24, and a door-closed standby determination unit 25. Note that these processing units are actually realized by software or a combination of software and hardware.

[0015] The call memory unit 21 stores, for each user who has registered a destination call by operating the landing destination floor registration device 14 on each floor, the destination call information (departure floor and destination floor) of each user, body temperature information, and information on the car (assigned car) to which the destination call is assigned, in association with each other.

[0016] The carpooling determination unit 22 determines which cars will be shared by users with a body temperature above a certain value (hereinafter referred to as "high body temperature users") and users with a body temperature below a certain value (hereinafter referred to as "normal body temperature users"), based on the user's boarding section obtained from the destination call information and each user's boarding section obtained from the currently registered destination call information. The "certain value" is, for example, 37.5 degrees, which has been established as an index for determining viral infection. The process of determining which cars will be shared will be described in detail later.

[0017] The allocation control unit 23 determines the optimal car from among the cars to be allocated as the assigned car based on the operation information of each car (current car position, driving direction, etc.) for the destination call registered through the hall destination floor registration device 14, and causes the assigned car to respond to the registered floor of the destination call. For example, the allocation control is performed such that users having the same destination floor board the same car, taking into consideration the destination floor of the user. However, if there is a car that is determined by the carpooling determination unit 22 to be shared with a person with a high body temperature, the allocation control unit 23 excludes that car from the allocation targets and determines the assigned car.

[0018] The ventilation determination unit 24 determines whether or not a certain period of ventilation is required for a car that has arrived at a destination floor. In detail, the ventilation determination unit 24 determines that a certain period of ventilation is required when a car in which a person with a high body temperature has been riding arrives at the destination floor of the person with a high body temperature. The "certain period of time" is set according to the time required to replace the air in the car by driving the fan in the car, and is, for example, two minutes. This certain period of time can be set arbitrarily according to the size of the car, the performance of the fan, etc.

[0019] The door closed standby determination unit 25 determines whether or not a door closed standby is required for the assigned car determined by the allocation control unit 23. In detail, when a car in which a person with a high body temperature was riding is determined as an assigned car, the door closed standby determination unit 25 determines that the car needs to wait with the door closed without opening the door until ventilation for a certain period of time is completed. The allocation control unit 23 has a function of performing ventilation control in response to the determination result of the ventilation determination unit 24, and a function of performing door opening / closing control in response to the determination result of the door closed standby determination unit 25.

[0020] FIG. 2 is a diagram showing the configuration of the landing / destination floor registration device 14. As shown in FIG. The landing destination floor registration device 14 has an operation unit 14a for inputting the destination floor of the user, and a display unit 14b for displaying a car (assigned car) to which a destination call having the destination floor inputted by the operation unit 14a is assigned. In this embodiment, a temperature measuring device 15 is installed on the installation surface of the operation unit 14a and the display unit 14b in the landing destination floor registration device 14. Information on the user's body temperature detected by this temperature measuring device 15 is displayed on the display unit 14b.

[0021] Although the destination floor is generally input by operating a numeric keypad, it may be input by using an IC card, etc. Also, the hall destination floor registration device 14 may be installed in a place away from the hall.

[0022] In the example of Figure 2, a user with a body temperature of 36.5 degrees has entered 5F as the destination floor, and car 12a of car A has been assigned to him / her. The user will wait at the boarding area of ​​car A according to this display.

[0023] FIG. 3 is a diagram showing an example of information stored in the call storage unit 21. As shown in FIG. The information of the destination call registered through the landing destination floor registration device 14 is stored in the call storage unit 21 together with the body temperature information of the user who registered the destination call. In addition, when the car to be assigned to the destination call is determined, the assigned car information is stored in association with the destination call.

[0024] P1 to P6 in the figure indicate users. In the example of Fig. 3, user: P1, body temperature: 36.6°C, registered floor: 1F, destination floor: 5F, assigned car: car C are stored in the call memory unit 21. This means that user P1, who has a body temperature of 36.6°C, operates the hall destination floor registration device 14 on 1F to register 5F as the destination floor, and car C was assigned at that time. The same applies to P2 to P6.

[0025] Next, the operation of this system will be described. 4 is a flowchart showing the operation of this system. The processing shown in this flowchart is executed primarily by the group management control device 20, which is a computer.

[0026] Assume that a new destination call is registered by a user operating the landing destination floor registration device 14 at a landing on any floor (Yes in step S11). At this time, the temperature of the registered user is detected by the temperature measuring device 15 installed in the landing destination floor registration device 14. The user's body temperature information is transmitted from the landing destination floor registration device 14 to the group management control device 20 together with the information of the new destination call.

[0027] In the group management control device 20, the carpooling determination unit 22 determines whether the user who registered the new destination call has a high body temperature (step S12). In detail, the carpooling determination unit 22 determines that the user has a high body temperature when the body temperature of the user sent from the hall destination floor registration device 14 is equal to or higher than a certain value.

[0028] If it is determined that the user who registered the new destination call is a person with a high body temperature (Yes in step S12), the carpooling determination unit 22 compares the boarding section obtained from the destination call registered by the person with a high body temperature with the boarding section of the person with a normal body temperature obtained from the registered destination call (unanswered destination call) stored in the call storage unit 21 (step S13). In detail, the carpooling determination unit 22 extracts the destination call of a user whose body temperature is below a certain value from the call storage unit 21 as a destination call registered by a person with a normal body temperature, and detects the boarding section from the registered floor and destination floor included in the destination call. For example, if the registered floor is 1F and the destination floor is 5F, the boarding section is from 1F to 5F. If the call storage unit 21 stores many destination calls of people with a normal body temperature, these destination calls are extracted in order, and the boarding section is extracted for each of them, and compared with the boarding section of the person with a high body temperature who is a registered user in the same manner as above.

[0029] The ride-sharing determination unit 22 determines whether the riding section of the high body temperature person who has registered a new destination call overlaps with the riding section of the normal body temperature person (step S14). Overlapping riding sections means that at least a portion of the two riding sections overlap. For example, if the riding section of user Pa is from 1F to 5F and the riding section of user Pb is from 3F to 4F, the riding section of user Pa and the riding section of user Pb overlap from 3F to 4F. Also, if the riding section of user Pc is from 1F to 4F and the riding section of user Pd is from 4F to 5F, the riding section of user Pc does not overlap with the riding section of user Pd.

[0030] If it is determined that the riding section of the high body temperature person overlaps with the riding section of the normal body temperature person (Yes in step S14), the allocation control unit 23 excludes the car in which the normal body temperature person is riding from the allocation targets (step S15). This is because if the riding section of the high body temperature person overlaps with the riding section of the normal body temperature person, if a new destination call is assigned to the car in which the normal body temperature person is riding, the high body temperature person and the normal body temperature person will ride together. After step S15, the allocation control unit 23 determines the car to which the destination call registered by the high body temperature person should be assigned from among the cars to be assigned (step S16).

[0031] In addition, if it is determined that the riding section of the high body temperature person does not overlap with the riding section of the normal body temperature person, that is, there is no car available for sharing with the normal body temperature person (No in step S14), the allocation control unit 23 determines the car to which to allocate the destination call registered by the high body temperature person from among all the cars eligible for allocation (step S16).

[0032] On the other hand, if it is determined that the user who registered the new destination call is not a person with a high body temperature, that is, a person with a normal body temperature (No in step S12), the ride-sharing determination unit 22 compares the riding section obtained from the destination call registered by the normal body temperature person with the riding section of the person with a high body temperature obtained from the registered destination calls stored in the call storage unit 21 (step S17). In this case as well, if many destination calls of people with high body temperatures are stored in the call storage unit 21, these destination calls are extracted in sequence, the riding section of each is detected, and compared with the riding section of the registered person with a normal body temperature in the same manner as above.

[0033] The ride-sharing determination unit 22 determines whether the riding section of the normal body temperature person who has registered a new destination call overlaps with the riding section of the high body temperature person (step S18). If it is determined that the riding section of the normal body temperature person overlaps with the riding section of the high body temperature person (Yes in step S18), the allocation control unit 23 excludes the car in which the high body temperature person is riding from the cars to be allocated (step S19). After step S19, the allocation control unit 23 determines the car to be allocated to the destination call registered by the normal body temperature person from among the cars to be allocated (step S16).

[0034] In addition, if it is determined that the riding section of the normal body temperature person does not overlap with the riding section of the high body temperature person, that is, there is no car available for sharing with the high body temperature person (No in step S18), the allocation control unit 23 determines which car to allocate to the destination call registered by the normal body temperature person from among all cars eligible for allocation (step S16).

[0035] Figure 5 shows a specific example of a case where a destination call registered by a person with a high body temperature is not assigned to a car to be shared with a person with a normal body temperature. Car 12a of car A is in operation, carrying a person with a normal body temperature whose destination floor is 2F, and is located near 4F. Car 12b of car B is in operation, carrying a person with a normal body temperature whose destination floor is 4F, and is located near 1F. Car 12c of car C is in a non-directional waiting state, and is located on 5F.

[0036] Now, suppose that a person with a high body temperature of 37.8°C operates the 2nd floor boarding hall destination floor registration device 14 and registers a new destination call with the 4th floor as the destination floor. Because the person who registered the new destination call is a person with a high body temperature, the boarding section of the person with a high body temperature (2nd floor to 4th floor) is compared with the boarding sections of each person with a normal body temperature obtained from the registered destination calls.

[0037] The boarding section of the normal body temperature person obtained from the registered destination call is 4F to 2F of the normal body temperature person who boarded the car 12a of the car A, and 1F to 4F of the normal body temperature person who boarded the car 12b of the car B. The boarding section of the normal body temperature person who boarded the car 12b of the car B overlaps with the boarding section of the high body temperature person who is a destination call registered, from 2F to 4F. Therefore, the car 12b of the car B is excluded from the allocation target. The allocation control unit 23 determines the assigned car from the cars to be assigned, excluding the car 12b of the car B. In this example, the car 12a of the car A can respond to the destination call of 2F earlier than the car 12c of the car C, so the car 12a of the car A is determined as the assigned car. The display unit 14b of the boarding hall destination floor registration device 14 displays the information of the car A as the assigned car and the body temperature information of the registered high body temperature person.

[0038] Figure 6 shows a specific example of a case in which a car sharing with a person with a high body temperature is not assigned to a destination call registered by a person with a normal body temperature. Car 12a of car A is in a directionless standby state and is located on the second floor. Car 12b of car B is in operation toward the second floor, carrying a person with a high body temperature of 38.1 degrees, and is located near the fifth floor. Car 12c of car C is in operation toward the second floor, carrying a person with a normal body temperature, and is located near the fifth floor.

[0039] Now, suppose that a person with a normal body temperature of 36.3°C operates the 4F boarding hall destination floor registration device 14 and registers a new destination call with the destination floor of 2F. Because the person who registered the new destination call is a person with a normal body temperature, the boarding section of the normal body temperature person (4F to 2F) is compared with the boarding sections of each person with a high body temperature obtained from the registered destination calls.

[0040] The boarding section of the person with high body temperature obtained from the registered destination call is from 5F to 2F, which overlaps with the boarding section of the person with normal body temperature who is a registered destination call, from 4F to 2F. Therefore, car 12b of car B, in which the person with high body temperature boarded, is excluded from the allocation targets. The allocation control unit 23 determines the assigned car from among the cars to be assigned, excluding car 12b of car B. In this example, car 12c of car C can respond to the destination call for 4F earlier than car 12a of car A, so car 12c of car C is determined as the assigned car. The display unit 14b of the hall destination floor registration device 14 displays information on car C as the assigned car and the body temperature information of the registered person with normal body temperature.

[0041] In this way, according to this embodiment, by excluding from the allocation targets cars in which normal body temperature passengers and high body temperature passengers are sharing based on the boarding section obtained from the destination call of each user, it is possible to operate the train while avoiding passengers with normal body temperature and high body temperature riding together. This makes it possible to prevent infection by riding together with a user who is suspected of being infected based on his / her body temperature.

[0042] If a person with a normal body temperature gets into a car in which a person with a high body temperature (a passenger suspected of infection) has been riding and the car is not adequately ventilated, the risk of the person with a normal body temperature becoming infected increases. Therefore, it is preferable to designate the car in which the person with a high body temperature has been riding as the car to be ventilated, and to operate the fan with the door closed when the person with a high body temperature gets off, and to exclude the car from the allocation targets until ventilation for a certain period of time is completed.

[0043] FIG. 7 shows the processing operation for excluding a car in which a person with a high body temperature is riding from the allocation targets. Assume that the car carrying the user has arrived at the destination floor (Yes in step S21). The ventilation determination unit 24 determines whether the user in the car has a high body temperature (step S22). In detail, the ventilation determination unit 24 reads the body temperature information of the user associated with the car information from the memory unit 21, and determines whether it is equal to or higher than a certain value.

[0044] If the passenger in the car has a high body temperature (Yes in step S22), the allocation control unit 23 operates the fan with the door of the car closed after the passenger with a high body temperature gets off to ventilate the car for a certain period of time, and restricts the allocation of destination calls to the car during that period (step S23). The car with the restricted allocation is excluded from the allocation targets until the ventilation for the certain period of time is completed. On the other hand, if the passenger in the car does not have a high body temperature (No in step S22), the allocation of the car is not restricted and it continues to be eligible for allocation.

[0045] FIG. 8 shows a specific example of excluding a car in which a person with a high body temperature is riding from the allocation targets until ventilation for a certain period of time is completed. Now, assume that a person with a high body temperature of 37.6 degrees who was in car 12b of car B gets off at the destination floor, 2F. At this time, car 12b of car B is excluded from the allocation targets until ventilation for a certain period of time (for example, 2 minutes) is completed, because a person with a high body temperature was in car 12b.

[0046] Here, for example, assume that a person with a normal body temperature, for example 35.9 degrees, operates the destination floor registration device 14 at the 1st floor boarding hall and registers a new destination call with the 5th floor as the destination floor. The car 12a of car A is in a directionless waiting state and is located on the 5th floor. The car 12c of car C is operating with a person with a normal body temperature whose destination floor is the 5th floor on board and is located near the 3rd floor.

[0047] In such a case, the allocation control unit 23 determines the assigned car from among the allocation targets excluding the car 12b of car B. In this example, the car 12a of car A can respond to the destination call for 1F earlier than the car 12c of car C, so the car 12a of car A is determined as the assigned car. The display unit 14b of the hall destination floor registration device 14 on the 1st floor displays information about car A as the assigned car and the body temperature information of the registered normal body temperature person.

[0048] In this way, by limiting allocation to cars in which a person with a high body temperature has been riding and making them eligible for allocation after ventilation has been completed, regular users can ride in cars that have been sufficiently ventilated, thereby reducing the risk of infection inside the car.

[0049] In the above embodiment, the description is given on the assumption that the temperature measuring device 15 is incorporated in the landing destination floor registration device 14, but a standalone temperature measuring device 15 may be connected externally to the landing destination floor registration device 14. In this case, the temperature measuring device 15 displays the body temperature of the user who has registered the destination call, and the body temperature information may be sent directly to the group management control device 20, or may be sent to the group management control device 20 via the landing destination floor registration device 14. In addition, the temperature measuring device 15 may have a function to determine whether the person has a high body temperature or a normal body temperature based on the body temperature information, and only the determination result (information indicating the person with a high body temperature / normal body temperature) may be sent to the group management control device 20. Further, part of the functions of the group management control device 20 may be included in the hall / destination floor registration device 14.

[0050] (Example of change) (1) Allocation control, including the car in which the person with a high body temperature was riding In the above embodiment, the car in which the person with a high body temperature got on was excluded from the allocation target until the ventilation for a certain period (for example, 2 minutes) was completed after the person with a high body temperature got off, but even including this ventilation time, there are cases where the car can respond faster than other cars. However, considering the risk of infection, it is desirable to keep the door closed and not open when the car arrives at the registered floor of the destination call until the ventilation for a certain period is completed.

[0051] FIG. 9 is a flow chart showing a process in a first variation example in which a car in which a person with a high body temperature is riding is determined as an assigned car. Now, let us assume that a person with a high body temperature gets off the train at their destination floor. Assume that a new destination call is registered by a user operating the hall destination floor registration device 14 at a hall on any floor (Yes in step S31). The allocation control unit 23 includes the car in which the person with a high body temperature was riding in as an allocation target, and determines an assigned car from among the allocation targets according to a predetermined allocation evaluation formula (step S32). Whether or not a car is one in which a person with a high body temperature was riding can be determined from the body temperature information of users for each car stored in the call storage unit 21. For cars in which a person with a high body temperature was riding, allocation evaluation is performed taking into account the remaining time from the current time until a certain period of ventilation is completed and the response time of the destination call.

[0052] The allocation control unit 23 causes the elevator determined as the assigned elevator to respond to the registered floor of the destination call (step S33). Here, when the elevator (assigned elevator) arrives at the registered floor of the destination call, the allocation control unit 23 determines whether or not a person with a high body temperature was in the elevator before the destination call was assigned (step S34).

[0053] If the car was in a passenger with a high body temperature (Yes in step S34), the allocation control unit 23 keeps the car waiting at the registered floor with the doors closed and without opening them until ventilation of the car is complete (step S35). By keeping the doors closed until ventilation for a certain period of time is complete, passengers can board a car that is sufficiently ventilated, reducing the risk of infection in the car. On the other hand, if the car was not in a passenger with a high body temperature (No in step S34), the allocation control unit 23 opens the doors as usual when the car arrives and lets passengers waiting at the landing board.

[0054] FIG. 10 shows an example of a case where the car in which the person with a high body temperature was riding is assigned to respond to a registered floor of a destination call. Car 12a of car A is in operation, carrying a person with a normal body temperature whose destination is 11F, and is assumed to be near the 5th floor. Car 12b of car B is in ventilation after a person with a high body temperature of 37.6 degrees got off on the 2nd floor. Car 12c of car C is in operation, carrying a person with a normal body temperature whose destination is 12F, and is assumed to be near the 4th floor.

[0055] Now, assume that a person with a normal body temperature, who has a body temperature of 35.9 degrees, operates the 1F hall destination floor registration device 14 and registers a new destination call with the 5F as the destination floor. The allocation control unit 23 includes the car 12b of the car B in the allocation targets, and determines the assigned car from among the allocation targets. In this example, the car 12b of the car B can respond to the 1F destination call earlier than the car 12a of the car A and the car 12c of the car C, so the car of the car B is determined as the assigned car. The display unit 14b of the 1F hall destination floor registration device 14 displays information about the car B as the assigned car and the body temperature information of the registered person.

[0056] The allocation control unit 23 causes the assigned car to respond to 1F, which is the registered floor of the destination call. Since the assigned car, car 12b of car B, had a person with a high body temperature aboard, when the car arrived at the registered floor of the destination call, the car was kept in a closed state until ventilation for a certain period of time was completed.

[0057] Here, if the fan is driven to ventilate the car 12b of the vehicle B while it is moving from the 2nd floor to the 1st floor, the door will be kept closed when it arrives at the 1st floor until the ventilation is completed for the remaining time excluding the ventilation time during the movement. For example, if the fixed ventilation time is 2 minutes, and the car 12b of the vehicle B has completed 30 seconds of ventilation while moving from the 2nd floor to the 1st floor, the door will be closed until the remaining 1 minute and 30 seconds of ventilation is completed when it arrives at the 1st floor. Also, for example, if the car 12b of the vehicle B has completed ventilation for only 1 minute while waiting at the 2nd floor, the door will be closed until the remaining 30 seconds of ventilation is completed when it arrives at the 1st floor, including the 30 seconds of the movement from the 2nd floor to the 1st floor. In other words, even if the car 12b of the vehicle B is assigned as an assigned car and is made to respond to a destination call registered at the 1st floor, the door will be kept closed until the total of 2 minutes of ventilation is completed to create a clean state.

[0058] The lantern installed at the boarding area to notify arrivals is to be turned on when the two minutes of ventilation is complete, not just before the arrival of car 12b of car B. This is because if the lantern is turned on just before the arrival of car 12b of car B, passengers (those who have registered their destination calls) waiting at the boarding area will become suspicious that the doors will not open immediately.

[0059] In this way, when a new destination call is registered, if the allocation process is performed including the car in which the person with a high body temperature boarded, the car can respond to the destination call early without waiting for a certain period of ventilation to be completed at the floor where the person with a high body temperature disembarked, thereby preventing a decrease in operating efficiency.

[0060] In addition, if a person with a high body temperature registers a destination call on the 1st floor, when car 12b of car B in which the person with a high body temperature was riding arrives at the 1st floor as an assigned car, the doors may be opened without waiting for the completion of a certain period of ventilation.

[0061] (2) Highlighting the body temperature of people with high body temperature When a person with a high body temperature registers a destination call, the body temperature detected by the temperature measuring device 15 may be highlighted. In the example of Fig. 11, it is displayed that a user with a body temperature of 37.8 degrees inputs 4F as the destination floor and is assigned car 12a of car A. Since the registered person has a high body temperature, the body temperature is highlighted.

[0062] Methods of highlighting include, for example, displaying the temperature of a person with a normal body temperature in a larger size than that of a person with a normal body temperature, displaying the temperature of a person with a normal body temperature in a different color (e.g., red), underlining or adding a mark to the temperature of a person with a high body temperature, etc. By highlighting the temperature of a person with a high body temperature using at least one of these methods, it is possible to make the person with a high body temperature aware that they have a high body temperature and to increase their awareness of infection.

[0063] According to at least one of the embodiments described above, an elevator group management system can be provided that can avoid riding with passengers suspected of infection and prevent infection inside the elevator car.

[0064] Although some embodiments of the present invention have been described, these embodiments are presented as examples and are not intended to limit the scope of the invention. These embodiments can be implemented in various other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention. These embodiments and their modifications are included in the scope of the invention and its equivalents described in the claims, as well as in the scope and spirit of the invention.
