Description

[Technical field]

[0001] FIELD OF THE DISCLOSURE An embodiment of the present invention relates to an elevator system. [Background technology]

[0002] In recent years, it has been considered that mobile objects such as autonomous robots (hereinafter referred to as service robots) will move (drive) around a building to provide various services, such as transporting (carrying) luggage within the building and providing security within the building.

[0003] When the building in which the service robot moves is, for example, a multi-story building, the service robot can move between the multiple floors of the building by using an elevator provided in the building.

[0004] Incidentally, elevators are equipped with a fire control operation function (fire control operation mode) that stops the elevator at an evacuation floor and allows passengers to disembark at the evacuation floor when a fire breaks out in the building. This function reduces the risk of passengers being trapped in the elevator car when a fire breaks out in the building.

[0005] However, in the case of a service robot, even if the elevator arrives at an evacuation floor due to the fire control operation function, the service robot cannot recognize the evacuation floor as a floor to disembark unless the evacuation floor is the destination floor of the service robot, which means that the service robot may be trapped inside the elevator car.

[0007] The problem to be solved by the present invention is to provide an elevator system capable of preventing a service robot from being trapped inside the elevator car during fire control operation. [Means for solving the problem]

[0008] An elevator system according to one embodiment is a system in which a moving object moving in a building in which an elevator is installed and an elevator control device that controls the operation of the elevator are communicably connected. The elevator control device includes a fire detection unit that detects the occurrence of a fire, an entry / exit determination unit that determines whether the moving object is in the elevator based on a signal transmitted by the moving object, the entry signal indicating that the moving object has entered the elevator and a departure signal indicating that the moving object has exited the elevator, and a control unit that, when the occurrence of a fire is detected by the fire detection unit, switches from normal operation to a fire control operation in which the elevator is moved to an evacuation floor and the doors of the elevator are controlled to open, and, when the entry / exit determination unit determines that the moving object is in the elevator, transmits a change command to the moving object to change the destination floor of the moving object to the evacuation floor. When the control unit cannot receive the disembarkation signal from the moving body even though the elevator has landed at the evacuation floor and the doors have been opened and closed, the control unit resends the change command to the moving body and reopens the doors.

[0010] 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.

[0011] In the embodiment, it is assumed that a mobile object moves within a building to provide various services. The mobile object includes an autonomous robot (hereinafter, referred to as a service robot) that provides services such as transporting (carrying) luggage within the building and guarding the building.

[0012] Here, if the building in which the service robot moves has multiple floors, the service robot can move between the multiple floors by using an elevator installed in the building. In addition to the above-mentioned buildings, hospitals and train stations with multiple floors are also considered as buildings in which the service robot moves.

[0013] An overview of an elevator system according to an embodiment will be described below with reference to Fig. 1. As shown in Fig. 1, the elevator system is composed of a car 10 (elevator), a fire alarm 20, an elevator control device 30, and a service robot 40. Note that Fig. 1 shows a state in which the service robot 40 is riding in the car 10 (a state in which the service robot 40 is inside the car 10).

[0014] The fire alarm 20 is installed in various places in the building in which the elevator car 10 is installed. When the fire alarm 20 detects the occurrence of a fire, the fire alarm 20 transmits a detection signal to the elevator control device 30 to notify the occurrence of the fire.

[0015] The elevator control device 30 is communicably connected to the service robot 40 via a network (public line network) such as the Internet. The elevator control device 30 controls a hoist (not shown) for raising and lowering the car 10, controls the opening and closing of doors, controls various devices (e.g., lighting, etc.) in the car 10, controls operations in cooperation with the service robot 40, and the like.

[0016] As one of the operations in cooperation with the service robot 40, the elevator control device 30 receives a movement request transmitted by the service robot 40 and controls the car 10 to respond to the movement request. The movement request is a request that the service robot 40 moves from a floor corresponding to a departure floor to a floor corresponding to a target floor (destination floor), and includes information indicating the departure floor and the target floor. The elevator control device 30 controls the car 10 to move from the departure floor to the target floor indicated by the received movement request.

[0017] As shown in FIG. 1, the elevator control device 30 includes a fire detection unit 31, an elevator control unit 32, a robot boarding / alighting determination unit 33, and a robot interlocking unit 34 (communication unit).

[0018] The fire detection unit 31 detects that a fire has occurred in the building based on the detection signal transmitted by the fire alarm 20, and outputs a fire detection signal to the elevator control unit 32 to indicate that a fire has been detected.

[0019] The elevator control unit 32 controls the operation of the fire detection unit 31, the robot boarding / alighting determination unit 33, and the robot interlocking unit 34, and also controls the operation of the car 10 based on various signals from the fire detection unit 31, the robot boarding / alighting determination unit 33, and the robot interlocking unit 34.

[0020] The elevator control unit 32 controls the operation of the car 10 based on the fire detection signal output by the fire detection unit 31. Specifically, the elevator control unit 32 switches the operation mode of the car 10 from a normal operation mode to a fire control operation mode, moves the car 10 to an evacuation floor, opens the door there, and controls the car 10 to wait, etc. The evacuation floor is a floor that is determined in advance as the most suitable floor for evacuation, and corresponds to a lobby floor, for example. According to this, when a fire breaks out in the building, the car 10 can be stopped at the evacuation floor and the passengers riding in the car 10 can be allowed to disembark at the evacuation floor, thereby reducing the risk of being trapped, etc.

[0021] In addition, when the elevator control unit 32 is in the car 10 during fire control operation mode (fire control operation), the elevator control unit 32 transmits a destination floor change command to the service robot 40 via the robot interlocking unit 34 to change the destination floor of the service robot 40 to an evacuation floor.

[0022] Furthermore, when the car 10 lands on the destination floor of the service robot 40, the elevator control unit 32 transmits a destination floor arrival notification that the car 10 has arrived at the destination floor (in other words, a notification encouraging the user to get off the car 10) to the service robot 40 via the robot interlocking unit 34. Although a detailed description is omitted in this specification, when the car 10 lands on the departure floor of the service robot 40, the elevator control unit 32 transmits a departure floor arrival notification that the car 10 has arrived at the departure floor (in other words, a notification encouraging the user to get on the car 10) to the service robot 40 via the robot interlocking unit 34.

[0023] The robot boarding / disembarking judgment unit 33 detects whether the service robot 40 has boarded or disembarked from the car 10 based on signals transmitted from the service robot 40, including a boarding signal indicating that the service robot 40 has boarded the car 10 and a disembarking signal indicating that the service robot 40 has disembarked from the car 10, and judges whether the service robot 40 is inside the car 10.

[0024] For example, when the robot boarding / alighting determination unit 33 receives a boarding signal transmitted by the service robot 40, it detects that the service robot 40 has boarded the car 10. In addition, when the robot boarding / alighting determination unit 33 receives a disembarking signal transmitted by the service robot 40, it detects that the service robot 40 has disembarked from the car 10.

[0025] When the above-mentioned boarding signal is received but the above-mentioned disembarking signal is not received, the robot boarding / alighting determination unit 33 determines that the service robot 40 is in the car 10 (in other words, detects that the service robot 40 is in the car 10). The result of the determination (detection) by the robot boarding / alighting determination unit 33 is sent to the elevator control unit 32.

[0026] The robot linking unit 34 is a communication interface for communicating with the service robot 40 . The robot interlocking unit 34 receives an entry signal transmitted by the service robot 40, and outputs the entry signal to the robot boarding / alighting determination unit 33. Similarly, the robot interlocking unit 34 receives an exit signal transmitted by the service robot 40, and outputs the exit signal to the robot boarding / alighting determination unit 33. Furthermore, the robot interlocking unit 34 transmits a destination floor change command output from the elevator control unit 32 to the service robot 40.

[0027] As shown in FIG. 1, the service robot 40 includes an elevator interlocking unit 41 (communication unit), a destination floor setting unit 42, a robot control unit 43, and a robot boarding / alighting transmission unit 44.

[0028] The elevator interlocking unit 41 is a communication interface for communicating with the elevator control device 30. The elevator interlocking unit 41 receives a destination floor change command transmitted by the elevator control device 30, and outputs the destination floor change command to the destination floor setting unit 42. The elevator interlocking unit 41 also receives a destination floor arrival notification transmitted by the elevator control device 30, and outputs the destination floor arrival notification to the robot control unit 43. Note that the elevator interlocking unit 41 also outputs the departure floor arrival notification to the robot control unit 43 when it receives the above-mentioned departure floor arrival notification.

[0029] The destination floor setting unit 42 has a function of setting a destination floor for the service robot 40. Based on a destination floor change command output from the elevator interlocking unit 41, the destination floor setting unit 42 changes the destination floor being set for the service robot 40 to the destination floor (in this case, the evacuation floor) indicated by the destination floor change command. In other words, the destination floor setting unit 42 changes the destination floor set when the service robot 40 transmits a movement request to the destination floor indicated by the destination floor change command. Information indicating the destination floor set for the service robot 40 is sent to the robot control unit 43.

[0030] The robot control unit 43 controls the operation of the elevator interlocking unit 41, the destination floor setting unit 42, and the robot boarding / alighting transmission unit 44, and also controls the operation of the service robot 40 based on various signals from the elevator interlocking unit 41 and the destination floor setting unit 42. The robot control unit 43 transmits the above-mentioned movement request to the elevator control device 30 via the elevator interlocking unit 41. The movement request is generated, for example, when the service robot 40 needs to use the car 10 when providing various services. When the above-mentioned movement request is transmitted to the elevator control device 30, the robot control unit 43 controls the operation of the service robot 40 so as to move from the departure floor to the destination floor indicated by the movement request.

[0031] Furthermore, the robot control unit 43 controls the operation (movement) of the service robot 40 so that the service robot 40 gets off the car 10 based on the destination floor arrival notification output from the elevator interlocking unit 41. The robot control unit 43 also controls the operation (movement) of the service robot 40 so that the service robot 40 gets on the car 10 based on the departure floor arrival notification output from the elevator interlocking unit 41.

[0032] Furthermore, the robot control unit 43 outputs a notification to the robot boarding / disembarking transmission unit 44 that the boarding / disembarking of the service robot 40 has been completed.

[0033] The robot boarding / alighting transmission unit 44 transmits an alighting signal indicating that the service robot 40 has alighted from the car 10 to the elevator control device 30 via the elevator interlocking unit 41 based on the notification output from the robot control unit 43 that the alighting of the service robot 40 has been completed. Also, the robot boarding / alighting transmission unit 44 transmits an alighting signal indicating that the service robot 40 has alighted from the car 10 to the elevator control device 30 via the elevator interlocking unit 41 based on the notification output from the robot control unit 43 that the alighting of the service robot 40 has been completed.

[0034] Next, an example of the operation of the elevator system according to this embodiment will be described with reference to the flowchart in Fig. 2. Note that, here, the operation when a fire breaks out in a building while the elevator car 10 is operating in the normal operation mode will be described.

[0035] When a fire is detected by the fire detection unit 31 included in the elevator control device 30 (step S1), the elevator control unit 32 switches the operation mode of the car 10 from a normal operation mode to a fire control operation mode, and controls the car 10 to move to an evacuation floor (step S2).

[0036] Next, the robot boarding / disembarking determination unit 33 determines whether or not the service robot 40 is in the car 10. Specifically, the robot boarding / disembarking determination unit 33 determines whether or not the service robot 40 is in the car 10 based on the boarding signal and the disembarking signal transmitted by the service robot 40 (step S3).

[0037] When the robot boarding / alighting determination unit 33 receives the boarding signal but fails to receive the disembarking signal, it determines that the service robot 40 is in the car 10. On the other hand, when the robot boarding / alighting determination unit 33 receives both the boarding signal and the disembarking signal (i.e., when it receives the boarding signal and the disembarking signal corresponding to the boarding signal), or when it does not receive the boarding signal at all, it determines that the service robot 40 is not in the car 10.

[0038] In the process of step S3, if it is determined that the service robot 40 is not inside the car 10 (step S3), the series of operations here ends.

[0039] On the other hand, if it is determined in the processing of step S3 that the service robot 40 is inside the elevator car 10 (Yes in step S3), the elevator control unit 32 sends a destination floor change command to the service robot 40 via the robot interlocking unit 34 to change the destination floor of the service robot 40 to an evacuation floor (step S4).

[0040] When the destination floor change command is received by the elevator interlocking unit 41 included in the service robot 40 (step S5), the destination floor setting unit 42 changes the destination floor set for the service robot 40 to the destination floor (i.e., the evacuation floor) indicated by the destination floor change command (step S6).

[0041] When the car 10 lands on the evacuation floor, the elevator control unit 32 included in the elevator control device 30 performs control to open the door of the car 10 (step S7). After that, the elevator control unit 32 transmits a destination floor arrival notification indicating that the car 10 has arrived at the destination floor of the service robot 40 (the evacuation floor in this case) to the service robot 40 via the robot interlocking unit 34 (step S8).

[0042] When the elevator interlocking unit 41 included in the service robot 40 receives a notification of arrival at the destination floor (step S9), the robot control unit 43 controls the operation (movement) of the service robot 40 so that the service robot 40 disembarks from the elevator car 10 (step S10).

[0043] When the disembarking of the service robot 40 is completed by the process of step S10, the robot boarding / disembarking transmitting unit 44 transmits a disembarking signal indicating that the service robot 40 has disembarked from the car 10 to the elevator control device 30 via the elevator interlocking unit 41 (step S11). After the process of step S11, the service robot 40 goes into a standby state near the landing. Note that the standby state here means a state in which various settings (e.g., the destination floor before the change) related to the movement request generated when boarding the car 10 this time are reset, and the service robot 40 waits for a new request for the provision of a predetermined service (e.g., a new request to transport an item from the first floor to the third floor).

[0044] Thereafter, the elevator control device 30 receives the disembarking signal transmitted by the service robot 40, and when it confirms that the service robot 40 has disembarked safely (normally) (step S12), it ends the series of operations.

[0045] Here, assuming a specific situation, the operation of the elevator system according to this embodiment will be described. In the following, as shown in FIG. 3, in an elevator system including one car 10 installed in a three-story building, a case is assumed in which a service robot 40 is aboard the car 10 and traveling from the first floor to the third floor, and a fire is detected while the car 10 is traveling between the first and second floors.

[0046] In this case, first, as shown in Fig. 3(a), the elevator control unit 32 included in the elevator control device 30 switches the operation mode of the car 10 to a fire control operation mode, and controls the car 10 to move to the first floor, which is an evacuation floor (lobby floor). The elevator control unit 32 also transmits a destination floor change command to the service robot 40 riding in the car 10, to change the currently set destination floor (the third floor in this case) to the first floor, which is an evacuation floor. The destination floor setting unit 42 included in the service robot 40 changes (sets) the destination floor from the third floor to the first floor, based on the destination floor change command transmitted by the elevator control device 30.

[0047] 3(b), when the car 10 lands on the first floor, which is an evacuation floor, the elevator control unit 32 included in the elevator control device 30 performs control to open the door of the car 10. In addition, the elevator control unit 32 transmits a destination floor arrival notification to the service robot 40 riding in the car 10, notifying the service robot 40 that it has arrived at the destination floor.

[0048] A robot control unit 43 included in the service robot 40 controls the operation (movement) of the service robot 40 so that the service robot 40 disembarks from the car 10 according to the destination floor arrival notification transmitted by the elevator control device 30. When the service robot 40 has completed disembarking, a robot boarding / disembarking transmission unit 44 transmits a disembarking signal indicating that the service robot 40 has disembarked from the car 10 to the elevator control device 30, as shown in FIG. 3(c).

[0049] According to this, even if a fire is detected while the service robot 40 is traveling in the car 10 and the car 10 moves to an evacuation floor on a floor other than the original destination floor in fire control operation mode, the service robot 40 can be made to disembark at an evacuation floor (first floor in the case of Figure 3) on a floor other than the original destination floor (third floor in the case of Figure 3), thereby preventing the service robot 40 from being trapped inside the car 10.

[0050] In the embodiment described above, the service robot 40 is in a standby state in which various settings (e.g., the destination floor before the change) related to the movement request generated when getting on the car 10 this time are reset after getting off at the evacuation floor, but for example, when the service robot 40 gets off at a floor (evacuation floor) different from the original destination floor, the various settings related to the movement request generated when getting on the car 10 this time may be saved as an error log, and when the operation of the car 10 is restored, the movement request for the various settings indicated by the error log may be sent again to the elevator control device 30 (that is, a call for moving to the destination floor before the change may be registered). In this way, the service robot 40 can automatically resume the provision of a service that has been interrupted due to, for example, a fire outbreak, together with the recovery of the elevator.

[0051] In the present embodiment, the service robot 40 gets off at the evacuation floor and then waits near the landing, but for example, the service robot 40 may move to an evacuation location set together with the evacuation floor, rather than waiting near the landing after getting off at the evacuation floor. In this case, the elevator control device 30 transmits location information indicating the location of the evacuation location of the service robot 40 together with a destination floor change command for changing the destination floor of the service robot 40 to the evacuation floor.

[0052] Here, assuming that a fire breaks out while the service robot 40 is transporting flammable medicines, for example, in a hospital, if the service robot 40 gets off at an evacuation floor and waits near the boarding area of ​​the evacuation floor, there is a possibility that the medicines will ignite and cause secondary damage if the fire reaches the evacuation floor; however, by moving the service robot 40 to an evacuation location away from the boarding area, the occurrence of such secondary damage can be prevented.

[0053] The following describes modified examples. (Modification) In this modified example, an operation will be described in a case where the elevator control device 30 sends a destination floor change command and a destination floor arrival notification to the service robot 40, but is unable to receive a disembarkation signal from the service robot 40.

[0054] Fig. 4 is a flow chart showing an example of the operation of the elevator control device 30 in the modified example. Note that detailed explanations of processes similar to those shown in Fig. 2 will be omitted here.

[0055] First, the processes of steps S21 to S26 are executed as processes similar to steps S1 to S4, S7, and S8 shown in Fig. 2. According to this, a destination floor change command and a destination floor arrival notice are transmitted from the elevator control device 30 to the service robot 40.

[0056] When a certain time has elapsed since the door of the car 10 was opened, the elevator control device 30 performs control to close the door of the car 10. At this time, the elevator control device 30 checks whether or not an alighting signal has been received from the service robot 40 (step S27).

[0057] If it is confirmed in the processing of step S27 that a disembarking signal has been received from the service robot 40 (Yes in step S27), the elevator control device 30 concludes that it has confirmed that the disembarking of the service robot 40 has been completed safely (normally), and ends this series of operations.

[0058] On the other hand, if it is confirmed in the processing of step S27 that the disembarking signal has not been received from the service robot 40 (No in step S27), the elevator control device 30 re-sends the destination floor change command sent in the processing of step S24 described above to the service robot 40, and performs control to reopen the doors of the car 10 (step S28), and then re-executes the processing of step S26 described above.

[0059] By executing the processes of steps S27 and S28 described above, the elevator control device 30 executes again the process of sending a destination floor change command to the service robot 40 and the process of sending a destination floor arrival notification to the service robot 40, and can cause the service robot 40 to disembark from the car 10 whose door has been reopened. This makes it possible to cope with a case where, for example, the communication situation is poor when the process of step S24 is executed, and the service robot 40 is unable to normally receive the destination floor change command sent from the elevator control device 30, and therefore is unable to change the destination floor of the service robot 40 to an evacuation floor.

[0060] When the door of the car 10 is reopened by the process of step S28 described above, the elevator control device 30 controls a display device (for example, an indicator showing the floor) installed on the landing side to display a notice that the elevator is currently unavailable due to the occurrence of a fire. This makes it possible to prevent a user from mistakenly getting on the car 10 whose door has been reopened.

[0061] According to the embodiment described above, it is possible to provide an elevator system capable of preventing the service robot 40 from being trapped inside the elevator (car 10) during fire control operation.

[0062] Although several 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 novel 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.
