A detailed explanation will be given below with reference to the drawings. Duplicate explanations will be simplified or omitted as appropriate. In each figure, the same reference numerals indicate the same or corresponding parts.

Embodiment 1.
FIG. 1 is a diagram showing an example of an elevator system 1 in the first embodiment. The elevator system 1 includes a plurality of cars 2. In the following, an example in which the elevator system 1 includes three cars 2 will be described. For example, the elevator system 1 includes a car 2 of an A car, a car 2 of a B car, and a car 2 of a C car. Note that the elevator system 1 may include only two cars 2. The elevator system 1 may include four or more cars 2.

Each car 2 stops at multiple floors within the building. FIG. 1 shows an example in which the car 2 stops at each of the first to ninth floors. A user can ride the car 2 and move to a desired floor.

The elevator system 1 includes a cleaning robot 3. FIG. 1 shows an example in which an elevator system 1 includes one robot 3 as the simplest example. The elevator system 1 may include a plurality of robots 3. The robot 3 can ride the cage 2 and move to each floor within the building. In the example shown in this embodiment, the robot 3 can ride the car 2 and move to each floor from the first floor to the ninth floor.

The robot 3 cleans the floor and the landing area on each floor. As an example, cleaning the landing area includes disinfecting the control panel, removing debris from the floor and handrails, etc. The operation panel may be a button type device or a touch panel type device. Further, the robot 3 cleans the car 2 while riding on the car 2.

The elevator system 1 further includes a storage section 10, an operation control section 11, a robot control section 12, a time measurement section 13, a time measurement section 14, and a number of people measurement section 15.

The operation control unit 11 receives a call request from a user. The operation control unit 11 also receives a call request for the robot 3. The call request includes departure floor information and destination floor information. The operation control unit 11 determines the car 2 that responds to the received request from among the plurality of cars 2 provided in the elevator system 1. In the following, the car 2 that responds to a call request, that is, the car 2 that is allocated to that request, will also be referred to as an assigned car.

A call request from a user is made by the user operating a control panel provided at the hall. The call request from the user may be made from a mobile terminal owned by the user. When the operation control unit 11 receives a call request from a user, it determines a car to be allocated to the request so as not to deteriorate the efficiency of the entire system. The operation control unit 11 determines the assigned car based on the destination floor of the user, the current position and movement direction of each car 2, and already registered calls.

On the other hand, a call request for the robot 3 is made by the robot control unit 12. The operation when the operation control unit 11 receives a call request for the robot 3 will be described later.

The robot control unit 12 controls the robot 3. For example, the robot control unit 12 instructs the robot 3 to clean. The robot 3 cleans the car 2 and each floor based on cleaning instructions from the robot control unit 12.

Further, the robot control unit 12 requests a call for the robot 3 to get on the car 2 and move to the destination floor. The operation control unit 11 determines an assigned car in response to a call request made by the robot control unit 12. When the operation control unit 11 determines the allocated car, the robot control unit 12 issues an operation instruction for the robot 3 to ride the allocated car and move to the destination floor. The robot 3 gets on and off the car 2 based on operation instructions from the robot control section 12.

In this manner, the robot 3 autonomously moves within the building and performs cleaning work upon receiving instructions from the robot control unit 12.

The storage unit 10 stores information necessary for the operation control unit 11 to determine an assigned car in response to a call request from the robot control unit 12. Further, the storage unit 10 stores information necessary for the robot control unit 12 to request a call, that is, information necessary for determining the destination floor of the robot 3. Table 1 shows an example of information stored in the storage unit 10.

The reference time t1 indicates a time interval that is a reference for cleaning the car 2. For example, the cleaning of the car 2 for which cleaning has not been performed for the reference time t1 or more is performed preferentially. That is, if there is a car 2 that has not been cleaned for 30 minutes or more, that car 2 will be cleaned with priority.

The reference number of users n1 indicates the cumulative number of users serving as a reference for cleaning the car 2. For example, priority is given to cleaning the car 2 for which the number of people using the car while cleaning is not performed is equal to or greater than the reference number n1. That is, if there is a car 2 in which the number of users since the last cleaning was 10 or more exists, that car 2 will be cleaned with priority.

The reference time t2 indicates a time interval that serves as a reference for cleaning each floor. For example, cleaning is given priority to floors on which no cleaning has been performed for the reference time t2 or longer. That is, if there is a floor that has not been cleaned for two hours or more, that floor will be cleaned with priority.

The reference time t3 indicates the time required for the robot 3 to clean the cage 2. In the example shown in Table 1, the robot 3 cleans the car 2 in 10 seconds.

A reference time t1, a reference number of people n1, a reference time t2, and a reference time t3 are set in advance.

The time measuring unit 13 measures the elapsed time since the last cleaning was performed for each floor on which the robot 3 can move. In the example shown in FIG. 1, the time measuring unit 13 measures the elapsed time since the last cleaning by the robot 3 for each of the first to ninth floors. FIG. 1 shows an example in which time measurement units 13 are provided corresponding to each of the first to ninth floors. Any method may be used by the time measurement unit 13 to measure the elapsed time.

The time measuring unit 14 measures the elapsed time since the last cleaning was performed for each of the cars 2 provided in the elevator system 1. In the example shown in this embodiment, the time measuring unit 14 measures the elapsed time since the last cleaning by the robot 3 for each of the three cars 2. FIG. 1 shows an example in which a time measuring section 14 is provided corresponding to each car 2. Any method may be used by the time measurement unit 14 to measure the elapsed time.

The number of people measuring unit 15 measures the number of users since the last cleaning of each car 2 provided in the elevator system 1. In the example shown in this embodiment, the number of people measuring unit 15 measures the number of users who have boarded each of the three cars 2 after the last cleaning by the robot 3 has been performed. FIG. 1 shows an example in which a number of people measuring section 15 is provided corresponding to each car 2.

The number of people measurement unit 15 may use any method to measure the number of people. For example, the number of people measuring unit 15 measures the number of people based on an image from a camera provided in the car 2 or a signal from a sensor. The number of people measurement unit 15 may measure the number of people based on a call request from a user. In such a case, the request will include information on the number of people. The number of people measuring section 15 may measure the number of people based on the number of registered calls.

Next, the operation of the elevator system 1 will be described with reference to FIGS. 2 to 4. FIG. 2 is a flowchart showing an example of the operation of the elevator system 1 in the first embodiment. In the following, the operation immediately after the robot 3 cleans the first floor will be described in detail.

When the cleaning of the first floor by the robot 3 is completed, in the elevator system 1, a process for determining the next destination floor of the robot 3 is started (S101). The next destination floor of the robot 3 is the floor on which the robot 3 cleans next. The destination floor of the robot 3 is determined by the robot control unit 12.

FIG. 3 is a flowchart showing an example of the operation of the robot control section 12. FIG. 3 shows a series of processes performed in S101. Basically, the robot control unit 12 determines the next destination floor of the robot 3 from among a plurality of floors to which the robot 3 can move, based on the elapsed time measured by the time measurement unit 13.

In the example shown in this embodiment, the robot control unit 12 determines the destination floor of the robot 3 by updating the list L1 according to conditions. First, the robot control unit 12 adds all floors to which the robot 3 can move to the list L1 as destination floor candidates for the robot 3 (S201). That is, the list L1 in S201 is [1F, 2F, 3F, 4F, 5F, 6F, 7F, 8F, 9F].

Next, the robot control unit 12 sorts the floors included in the list L1 in descending order of elapsed time since the last cleaning was performed (S202). The robot control unit 12 performs the sorting in S202 based on the elapsed time measured by the time measurement unit 13. Table 2 shows an example of elapsed time measured by the time measurement unit 13.

If the measurement results shown in Table 2 are obtained immediately after the robot 3 finishes cleaning the first floor, the list L1 in S202 will be [2F, 9F, 8F, 6F, 4F, 5F, 3F, 7F, 1F].

Next, the robot control unit 12 determines whether there is a floor that has not been cleaned for the reference time t2 or more (S203). The determination in S203 is made based on the elapsed time measured by the time measurement unit 13. In the example shown in Table 1, the reference time t2 is 2 hours. In the example shown in Table 2, the elapsed time on the second floor measured by the time measurement unit 13 is 2 hours and 30 minutes. The elapsed time on the 9th floor measured by the time measurement unit 13 is 2 hours. Therefore, the determination in S203 is Yes.

When the robot control unit 12 determines Yes in S203, the robot control unit 12 excludes from the list L1 the floors whose elapsed time measured by the time measurement unit 13 is shorter than the reference time t2. That is, the robot control unit 12 leaves only the floors whose elapsed time measured by the time measurement unit 13 is equal to or longer than the reference time t2 in the list L1 (S204). Therefore, the list L1 in S204 becomes [2F, 9F].

Note that if the robot control unit 12 determines No in S203, it does not update the list L1.

Next, the robot control unit 12 determines whether or not there is a floor among the floors remaining in the list L1 for which the ride time will be longer than the reference time t3 when the robot 3 rides on the car 2 and moves. (S205). Table 3 shows an example of the riding time when the robot 3 rides the car 2 from the first floor.

In the example shown in Table 1, the reference time t3 is 10 seconds. In the example shown in Table 3, when the robot 3 moves from the first floor to any floor above the fifth floor, the riding time becomes longer than 10 seconds. Since the list L1 includes the 9th floor, the determination in S205 is Yes.

If the robot control unit 12 determines Yes in S205, it excludes from the list L1 the floor where the ride time is shorter than the reference time t3 when the robot 3 rides on the car 2 and moves. That is, the robot control unit 12 leaves in the list L1 only the floors where the time the robot 3 is riding on the car 2 is longer than the reference time t3 (S206). Therefore, list L1 in S206 becomes [9F].

Note that if the robot control unit 12 determines No in S205, it does not update the list L1.

The robot control unit 12 determines the floor listed at the beginning of the list L1 as the destination floor of the robot 3 (S207). That is, the robot control unit 12 determines the ninth floor as the destination floor of the robot 3. After determining the destination floor of the robot 3 in S207, the robot control unit 12 outputs a call request based on the destination floor to the operation control unit 11.

When the destination floor of the robot 3 is determined in S101, the elevator system 1 starts processing for determining an assigned car (S102). The assigned car is the car 2 that responds to the destination floor determined by the robot control unit 12. The assigned car is determined by the operation control unit 11.

FIG. 4 is a flowchart showing an example of the operation of the operation control unit 11. FIG. 4 shows a series of processes performed in S102. Basically, the operation control unit 11 determines an assigned car from among the plurality of cars 2 provided in the elevator system 1 based on the elapsed time measured by the time measurement unit 14.

In the example shown in this embodiment, the operation control unit 11 determines the assigned car by updating the list L2 according to the conditions. First, the operation control unit 11 adds all the cars 2 provided in the elevator system 1 to the list L2 as candidates for allocated cars (S301). That is, the list L2 in S301 is [A, B, C]. In list L2, [A] indicates the car 2 of the A-th car, [B] shows the car 2 of the B-th car, and [C] shows the car 2 of the C car.

Next, the operation control unit 11 sorts the cars 2 included in the list L2 in descending order of elapsed time since the last cleaning was performed (S302). The operation control unit 11 performs the sorting in S302 based on the elapsed time measured by the time measurement unit 14. Table 4 shows an example of elapsed time measured by the time measurement unit 14.

If the measurement results shown in Table 4 are obtained immediately after the robot 3 finishes cleaning the first floor, the list L2 in S302 becomes [B, C, A].

Next, the operation control unit 11 determines whether there is a car 2 that has not been cleaned for the reference time t1 or more (S303). The determination in S303 is made based on the elapsed time measured by the time measurement unit 14. In the example shown in Table 1, the reference time t1 is 30 minutes. In the example shown in Table 4, the elapsed time of car 2 of car B measured by the time measurement unit 14 is 50 minutes. The elapsed time of car 2 of car No. C measured by the time measurement unit 14 is 30 minutes. Therefore, the determination in S303 is Yes.

When the operation control unit 11 determines Yes in S303, the operation control unit 11 excludes the car 2 whose elapsed time measured by the time measurement unit 14 is shorter than the reference time t1 from the list L2. That is, the operation control unit 11 leaves only the cars 2 whose elapsed time measured by the time measurement unit 14 is equal to or longer than the reference time t1 in the list L2 (S304). Therefore, list L2 in S304 becomes [B, C].

Note that if the operation control unit 11 determines No in S303, it does not update the list L2.

Next, the operation control unit 11 determines whether or not there is a car 2 that has been used by more than the reference number of people n1 since the previous cleaning among the cars 2 remaining in the list L2 (S305 ). The determination in S305 is made based on the number of people measured by the number of people measurement unit 15. Table 5 shows an example of the number of people measured by the number of people measuring section 15.

In the example shown in Table 1, the standard number of people n1 is 10 people. In the example shown in Table 5, the number of people in car 2 of car B after the last cleaning was 18. Therefore, the determination in S305 is Yes.

When the operation control unit 11 determines Yes in S305, the operation control unit 11 excludes from the list L2 the car 2 in which the number of people measured by the number of people measurement unit 15 is smaller than the reference number of people n1. That is, the operation control unit 11 leaves only the cars 2 in which the number of people measured by the number of people measuring unit 15 is equal to or greater than the reference number n1 in the list L2 (S306). Therefore, list L2 in S306 becomes [B].

Note that if the operation control unit 11 determines No in S305, it does not update the list L2.

Next, the operation control unit 11 determines whether or not there is a car 2 that does not respond to the user's call request in the riding section of the robot 3 among the cars 2 remaining in the list L2 (S307). . Table 6 shows an example of how robots 3 are allocated to users in riding sections.

In the example shown in Table 6, the car 2 of car B responds to a call request from the user in the section where the robot 3 rides, that is, the section from the 1st floor to the 9th floor. Therefore, the determination in S307 is No. If the operation control unit 11 determines No in S307, it does not update the list L2. Therefore, list L2 remains [B].

On the other hand, if the operation control unit 11 determines Yes in S307, it excludes the car 2 that responds to the call request by the user in the riding section of the robot 3 from the list L2. That is, the operation control unit 11 leaves only the cars 2 that do not respond to the call request from the user in the riding section of the robot 3 in the list L2 (S308).

In S309, the operation control unit 11 determines the car 2 listed at the top of the list L2 as the allocated car for the robot 3 to ride (S309). That is, the operation control unit 11 determines the car 2 of car B as the assigned car.

When the allocated car is determined in S309, the elevator system 1 starts processing for responding to the allocated car and for cleaning by the robot 3. In this process, the assigned car is controlled by the operation control unit 11. Control of the robot 3 is performed by a robot control section 12.

Specifically, the robot control unit 12 determines whether the assigned car, that is, car 2 of car B, has arrived at the landing on the departure floor (S103). The operation control unit 11 first causes the assigned car to respond to all requests from the user so that the user does not get on the car 2 while the robot 3 is riding on the car 2. Thereafter, the operation control section 11 causes the assigned car to respond to a request from the robot control section 12. When the assigned car arrives at the departure floor, that is, the landing on the first floor, the determination in S103 is Yes.

After the robot 3 finishes cleaning the first floor, it waits for the assigned car to arrive at the landing on the first floor. When the allocated car arrives at the first floor, the robot 3 gets on the allocated car (S104). If there is a user getting off the allocated car on the first floor, the robot 3 waits until all the users get off from the allocated car. When the robot 3 gets into the allocated car in S104, the allocated car is unmanned. After the robot 3 gets on the assigned car, the operation control unit 11 does not allow the assigned car to respond to other call requests until the assigned car arrives at the destination floor, that is, the 9th floor. This prevents the robot 3 and the user from riding together in the assigned car.

When the robot 3 gets on the allocated car, the robot 3 cleans the allocated car after the door is completely closed (S105). If the robot 3 finishes cleaning before the assigned car arrives at the 9th floor, it will wait in front of the door.

Thereafter, it is determined whether the assigned car has arrived at the destination floor, that is, the floor to be cleaned next (S106). As described above, after the robot 3 is placed in the assigned car on the first floor, the operation control unit 11 causes the assigned car to go directly to the ninth floor. When the assigned car arrives at the landing on the 9th floor, the determination in S106 is Yes. When the allocated car arrives at the 9th floor, the robot 3 gets off from the allocated car (S107). When the robot 3 gets off from the assigned car, it starts cleaning the floor on which it got off (S108).

When the cleaning of the 9th floor by the robot 3 is completed, the same process as described above is performed again. That is, the floor that the robot 3 will clean next is determined, and the assigned car for the robot 3 to go to that floor is determined. As a result, the robot 3 cleans the assigned car and the floor.

In the elevator system 1, the destination floor of the robot 3 is determined based on the elapsed time measured by the time measurement unit 13. Further, based on the elapsed time measured by the time measuring unit 14, an assigned car for responding to the destination floor is determined. Therefore, with the elevator system 1, efficient cleaning management using the cleaning robot 3 can be performed.

In the example shown in this embodiment, if there is a floor for which the elapsed time measured by the time measuring unit 13 is equal to or longer than the reference time t2, the floor is left in the list L1. That is, the robot control unit 12 prioritizes this floor and determines it as the destination floor of the robot 3. Therefore, it is possible to have the robot 3 preferentially clean floors that have not been cleaned for more than the reference time t2 since the last cleaning.

In the example shown in this embodiment, if there is a floor for which the robot 3 rides the car 2 from the floor it is currently on and travels thereon for a time equal to or longer than the reference time t3, that floor is left in the list L1. That is, the robot control unit 12 prioritizes this floor and determines it as the destination floor of the robot 3. Therefore, the robot 3 can finish cleaning the car 2 while moving on the car 2.

In the example shown in this embodiment, if there is a car 2 whose elapsed time measured by the time measurement unit 14 is equal to or longer than the reference time t1, the car 2 is left in the list L2. That is, the operation control unit 11 gives priority to the car 2 and determines it as the allocated car for the robot 3 to ride. Therefore, it is possible to have the robot 3 clean the car 2 which has not been cleaned for more than the reference time t1 since the last cleaning.

In the example shown in this embodiment, if there is a car 2 in which the number of people measured by the number of people measurement unit 15 is equal to or greater than the reference number n1, the car 2 is left in the list L2. That is, the operation control unit 11 gives priority to the car 2 and determines it as the allocated car for the robot 3 to ride. Therefore, it is possible to have the robot 3 clean the car 2 which has been used by more than the reference number n1 since the last cleaning.

In the elevator system 1, the time for cleaning each floor by the robot 3 may be determined in advance. In such a case, the next destination floor may be determined at the timing when the robot 3 arrives at a certain floor for cleaning, and the assigned car for going to the next destination floor may be determined. When the robot 3 completes cleaning on the floor it has arrived at, it can ride the reserved assigned car and move to the next destination floor without waiting at the landing.

In this embodiment, an example in which the elevator system 1 includes one robot 3 has been described. When the elevator system 1 includes a plurality of robots 3, the operations shown in FIGS. 2 to 4 are performed for each robot 3. In such a case, the information such as the elapsed time shown in Table 2, the elapsed time shown in Table 4, and the ride time shown in Table 5 can be used commonly by all robots 3. Further, when the elevator system 1 includes a plurality of robots 3, the assigned cars may be determined so that not only the users and the robots 3 are allowed to ride together, but also the robots 3 are prevented from riding together.

In this embodiment, an example has been described in which the boarding time shown in Table 3 is set in advance. Regarding the riding time shown in Table 3, a value calculated according to the situation at that time may be adopted.

In this embodiment, FIG. 3 shows a preferred operation flow for determining the destination floor of the robot 3. As another example, the robot control unit 12 may not perform the determination process shown in S203. The robot control unit 12 does not need to perform the determination process shown in S205.

In this embodiment, FIG. 4 shows a preferred operation flow for determining an assigned car. As another example, the operation control unit 11 may not perform the determination process shown in S303. The operation control unit 11 does not need to perform the determination process shown in S305. The operation control unit 11 does not need to perform the determination process shown in S307.

In addition, the operation control unit 11 may take into consideration the waiting time of the user, the waiting time of the robot 3, etc. in determining the assigned car so as not to deteriorate the efficiency of the entire system.

In the present embodiment, an example has been described in which the operation control unit 11 determines the assigned car from among the plurality of cars 2 provided in the elevator system 1 based on the elapsed time measured by the time measurement unit 14. As another example, the operation control unit 11 may determine the assigned car from among the plurality of cars 2 provided in the elevator system 1 based on the number of people measured by the number of people measuring unit 15.

In this case, in S302, the operation control unit 11 sorts the cars 2 included in the list L2 in descending order of the cumulative number of users since the last cleaning. If the measurement results shown in Table 5 are obtained immediately after the robot 3 finishes cleaning the first floor, the list L2 in S302 becomes [B, A, C]. After that, the operation control unit 11 may perform the processing shown from S303 onwards as necessary.

Some of the functions provided in the elevator system 1 may be provided in a server inside the building or a server outside the building. As an example, the operation control unit 11 is provided in an elevator control panel. The robot control unit 12 is provided in a server that is a different device from the elevator control panel. In such a case, communication between the control panel and the server may be performed using a specific network within the building, or may be performed using the Internet or the like.
