Description

[Technical field]

[0001] An embodiment of the present invention relates to an elevator control device and an elevator control method. [Background technology]

[0002] In recent years, autonomous mobile objects (hereafter simply referred to as "mobile objects") that perform tasks such as cleaning inside buildings, transporting luggage, and guiding building users have been put into practical use. In buildings with multiple floors, such as buildings, the use of elevators for the mobile objects is essential to perform the above tasks.

[0003] When a moving object uses an elevator, if the moving object and a user ride in the elevator together, the operating efficiency of the moving object may decrease, and the quality of service for the elevator user may decrease. In view of this, a technology has been disclosed that controls the operation of an elevator so as to avoid the moving object and the user riding in the elevator together by switching between an operation pattern that prioritizes the use of the moving object and an operation pattern that prioritizes the use of the user.

[0004] [Patent Document 1] Patent No. 6819767 Summary of the Invention [Problem to be solved by the invention]

[0005] However, even if the operation of the elevator is controlled as described above, there is a problem in that when priority is given to the use of a moving object, a passenger may enter the car through the gap between the moving object and the door when the door is open, thereby hindering the priority operation of the moving object.

[0006] The present invention has been made in consideration of the above circumstances, and aims to provide an elevator control device and an elevator control method that can reliably prevent a user from riding in an autonomously capable mobile body. [Means for solving the problem]

[0007] According to an embodiment for achieving the above object, an elevator control device includes a dimension information acquisition unit, a car opening determination unit, and a door opening / closing control unit. The dimension information acquisition unit acquires dimension information of an autonomously travelling mobile object that moves using an elevator. The car opening determination unit determines the opening degree of the car door of the elevator car when the mobile object gets into the car, based on the dimension information acquired by the dimension information acquisition unit. The door opening / closing control unit opens the car door to the opening degree determined by the car opening determination unit when the mobile object gets into the car.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] Hereinafter, as one embodiment of the present invention, an elevator system using a moving body such as a robot capable of autonomous travel (hereinafter, simply referred to as a "moving body") will be described.

[0010] First Embodiment Configuration of elevator system according to first embodiment 1 is an overall view showing the configuration of an elevator system 1A according to a first embodiment. The elevator system 1A includes an elevator 10A and a moving body 30 communicatively connected to the elevator 10A.

[0011] The elevator 10A includes a hoist 11, a car 13A suspended from a rope 12 stretched across the hoist 11, and an elevator control device 20A. The hoist 11 operates based on instructions from the elevator control device 20A to raise and lower the car 13A.

[0012] The car 13A is connected to the elevator control device 20A via a tail cord 14. The car 13A has an opening 131 on one side, and a car door 132A is installed in the opening 131. In this embodiment, the car door 132A moves upward to increase the opening degree of the opening 131 and open the door, and moves downward to decrease the opening degree of the opening 131 and close the door.

[0013] A camera device 133 is installed above the car door 132A to capture an image of the area below when the car door 132A is open. Fig. 1 shows the position of the camera device 133 when the car door 132A is fully open.

[0014] The elevator control device 20A includes a first wireless communication unit 21 and a first CPU 22A. The first wireless communication unit 21 performs wireless communication with the moving object 30.

[0015] The first CPU 22A is, for example, a CPU (Central Processing Unit) provided in a general-purpose microcomputer, and configures one or more information processing units described below by installing and executing a predetermined elevator control program. The first CPU 22A has a call registration unit 221, an elevator control unit 222, a dimension information acquisition unit 223, a car opening determination unit 224A, and a door opening / closing control unit 225 as the two or more information processing units.

[0016] The call registration unit 221 registers hall call information operated by a user on a hall operating panel (not shown) in the elevator 10A, car call information operated by a user on a car operating panel (not shown) in the car 13A, and call information acquired from the moving body 30 for the moving body 30 to use the elevator 10A. The elevator control unit 222 controls the operation of equipment in the elevator 10A, for example, the hoist 11, based on the information registered in the call registration unit 221.

[0017] The dimension information acquisition unit 223 acquires dimension information of the moving body 30. The car opening degree determination unit 224A determines the opening degree of the car door 132A when the moving body 30 gets into the car 13A, based on the dimension information of the moving body 30 acquired by the dimension information acquisition unit 223. The door opening / closing control unit 225 opens the car door 132A to the opening degree determined by the car opening degree determination unit 224A when the moving body 30 gets into the car 13A.

[0018] The moving body 30 has a second wireless communication unit 31, a movement mechanism 32, and a second CPU 33. The second wireless communication unit 31 performs wireless communication with the elevator control device 20A. The movement mechanism 32 is a mechanism that moves the moving body 30.

[0019] The second CPU 33 is, for example, a CPU (Central Processing Unit) provided in a general-purpose microcomputer, and configures one or more information processing units described below by installing and executing a predetermined mobile object control program. The second CPU 33 has a call information transmission unit 331 and an operation control unit 332 as the two or more information processing units.

[0020] When the moving body 30 uses the elevator 10A, the call information transmission unit 331 generates a call registration request including information on the boarding floor and disembarking floor of the moving body 30 and previously stored dimensional information of the moving body 30, and transmits it to the elevator control device 20A via the second wireless communication unit 31. The operation control unit 332 controls the movement mechanism 32.

[0021] Operation of the elevator system according to the first embodiment FIG. 2 is a flowchart showing the operation performed by the elevator control device 20A when the elevator system 1A according to this embodiment is in operation.

[0022] When the moving body 30 uses the elevator 10A, the call information transmission unit 331 of the moving body 30 generates a call registration request including information on the boarding floor and disembarking floor of the moving body 30 and previously stored dimensional information of the moving body 30, and transmits the call registration request to the elevator control device 20A via the second wireless communication unit 31. In this embodiment, the dimensional information of the moving body 30 includes information indicating the height of the moving body 30.

[0023] When the elevator control device 20A acquires the call information transmitted from the moving body 30, the call registration unit 221 registers the information on the boarding floor and disembarking floor of the moving body 30 included in the call information as call information of the moving body ("YES" in S1).

[0024] When the call information of the moving object 30 is registered, the dimension information acquisition unit 223 acquires information indicating the height of the dimension information of the moving object 30 included in the call information (S2), and sends it to the car opening degree determination unit 224A.

[0025] The cage opening degree determination unit 224A holds information on the height of the opening 131 when the cage door 132A of the cage 13A is fully open in advance. The cage opening degree determination unit 224A compares the held height of the opening 131 with the height of the moving body 30, and determines whether or not the difference is equal to or greater than a preset threshold value T1. This threshold value T1 is, for example, a difference value between the height of the opening 131 when the cage door 132A is fully open and a height equivalent to the height of a human being.

[0026] When the cage opening determination unit 224A determines that the difference between the height of the opening 131 and the height of the moving object 30 is equal to or greater than the threshold value T1 ("YES" in S3), it determines that the cage door 132A is opened with an opening degree dedicated to the moving object when the moving object 30 enters the cage 13A (S4). In this embodiment, the opening degree dedicated to the moving object is a value for opening the door to a height obtained by adding a predetermined value α to the height of the moving object 30, and is an opening degree to a position higher than the height of the moving object 30 and lower than the height of the opening 131 when the cage door 132A is fully opened. The value α is the height of the gap necessary for the moving object 30 to pass through the opening 131 safely.

[0027] FIG. 3(a) shows the car door 132A at a low height H R1 FIG. 1 is an explanatory diagram of the opening degree of the car determined when the moving body 30a of the car gets on. In this case, the height H D and the height H of the moving body 30 R1 Difference H D -H R1 is equal to or larger than the threshold value T1, the cage opening degree determination unit 224A determines whether the cage opening degree (H R1 It is determined that car door 132A is opened to an opening angle of α+α.

[0028] Also, in step S3, when the cage opening determination unit 224A determines that the difference between the height of the opening 131 and the height of the moving body 30 is less than the threshold value T1 ("NO" in S3), it determines that the cage door 132A will be opened at the normal opening, i.e., fully open, when the moving body 30 enters the cage 13A (S5).

[0029] FIG. 3(b) shows a high height H R2 FIG. 1 is an explanatory diagram of the opening degree of the car determined when the moving body 30b of the car gets on. In this case, the height H of the opening 131 is D and the height H of the moving body 30 R2 Difference H D -H R2is less than the threshold value T1, the car opening determination unit 224A determines that the car door 132A is to be fully opened when the moving object 30b gets on the car 13A.

[0030] The elevator control unit 222 moves the elevator car 13A to the boarding floor of the moving body 30 based on the call information of the moving body 30 registered in the call registration unit 221, and when the elevator car 13A lands on this boarding floor, the door opening / closing control unit 225 opens the elevator door 132A at the opening degree determined by the elevator opening degree determination unit 224A (S6).

[0031] When the door of the car 13A opens, the operation control unit 332 of the moving body 30 controls the moving mechanism 32, so that the moving body 30 gets on the car 13A.

[0032] When the elevator control unit 222 detects that the moving body 30 has entered the car 13A based on sensor information from a camera device (not shown) or a load detection device (not shown) installed on the car 13A ("YES" in S7), it causes the door opening / closing control unit 225 to close the car door 132A and move the car 13A to the disembarking floor of the moving body 30 (S8).

[0033] Here, when a hall call for another moving body at the floor where the elevator 13A has arrived is registered in the call registration unit 221 ("YES" in S9), the dimension information acquisition unit 223 acquires information indicating the height, which is the dimension information of the other moving body (S10).

[0034] The cage opening determination unit 224A selects the moving body that is taller between the moving body 30 and another moving body (S11), returns to step S3, and determines whether the difference between the height of the opening 131 and the height of the selected moving body 30 is greater than or equal to the threshold value T1 (S3).

[0035] Then, depending on the judgment result, the opening degree of the car door 132A is determined by processing in step S4 or S5, and when the car 13A lands at the disembarking floor of the moving body 30, the door opening / closing control unit 225 opens the car door 132A at the determined opening degree (S6).

[0036] When the door of the car 13A opens, the operation control unit 332 of the moving body 30 controls the moving mechanism 32 so that the moving body 30 gets off the car 13A, and then another moving body gets on.

[0037] In step S9, when no hall call for another moving body is registered in the call registration unit 221 ("NO" in S9), the car opening determination unit 224A determines that the car door 132A is to be opened in the fully open state when the moving body 30 disembarks (S12).

[0038] When the car 13A is fully opened (S13), the operation control unit 332 of the moving body 30 controls the movement mechanism 32, so that the moving body 30 gets off from the car 13A. When the moving body 30 gets off from the car 13A ("YES" in S14), the process returns to step S1.

[0039] According to the above first embodiment, when a moving object boards an elevator having a car whose doors open in the vertical direction, if the height of the moving object is lower than the height of the opening of the car by a predetermined value or more, the car doors are opened with as low an opening angle as possible while still allowing the moving object to board, making it difficult for users at the landing to board the car together with the moving object, and thus making it possible to avoid passengers riding with the moving object.

[0040] In the above-described first embodiment, when a plurality of moving bodies simultaneously enter the car 13A, the dimension information acquisition unit 223 may acquire the dimension information of the plurality of moving bodies, and the car opening degree determination unit 224A may determine the opening degree of the car door 132A by determining whether or not the difference between the height of the moving body with the largest dimension information, specifically the tallest moving body, among the plurality of moving bodies, and the height of the opening 131 is equal to or greater than the threshold value T1. By performing the process in this manner, the plurality of moving bodies can reliably enter the car 13A with a single door opening operation.

[0041] Second Embodiment Configuration of elevator system according to second embodiment The elevator system 1B according to the second embodiment has a similar configuration to the elevator system 1A described in the first embodiment, and therefore detailed descriptions of parts having the same functions will be omitted.

[0042] In this embodiment, a car 13B of an elevator 10B has an opening 131 on one side, and a car door 132B is installed in the opening 131. In this embodiment, the car door 132B changes the opening degree of the opening 131 by appropriately moving in the left-right direction.

[0043] Operation of the elevator system according to the second embodiment The operation performed by the elevator control device 20B when the elevator system 1B according to this embodiment is in operation will be described with reference to the flowchart of FIG.

[0044] When the moving body 30 uses the elevator 10B, the call information transmission unit 331 of the moving body 30 generates a call registration request including information on the boarding floor and disembarking floor of the moving body 30 and dimensional information of the moving body 30 stored in advance, and transmits the call registration request to the elevator control device 20B via the second wireless communication unit 31. In this embodiment, the dimensional information of the moving body 30 includes information indicating the width of the moving body 30.

[0045] When the elevator control device 20B acquires the call information transmitted from the mobile object 30, the call registration unit 221 registers the information on the boarding floor and the disembarking floor of the mobile object 30 included in the call information ("YES" in S1).

[0046] When the call information of the moving object 30 is registered, the dimension information acquisition unit 223 acquires information indicating the width of the moving object 30 contained in the call information (S2), and sends it to the car opening degree determination unit 224B.

[0047] The cage opening degree determination unit 224B holds information on the width of the opening when the cage door 132B of the cage 13B is fully open in advance. The cage opening degree determination unit 224B compares the held width of the opening 131 with the width of the moving body 30, and determines whether or not the difference is equal to or greater than a preset threshold value T2. This threshold value T2 is, for example, a value obtained by subtracting twice the width through which a person can pass from the width of the opening 131 when the cage door 132B is fully open.

[0048] When the cage opening determination unit 224B determines that the difference between the width of the opening 131 and the width of the moving object 30 is equal to or greater than the threshold value T2 ("YES" in S3), it determines that the cage door 132B is opened with an opening degree dedicated to the moving object when the moving object 30 enters the cage 13B (S4). In this embodiment, the opening degree dedicated to the moving object is a value for opening the door to a width obtained by adding a predetermined value α to the width of the moving object 30, and is an opening degree to a position that is wider than the width of the moving object 30 and narrower than the width of the opening 131 when the cage door 132B is fully open. The value α is the width of the gap necessary for the moving object 30 to pass through the opening 131 safely.

[0049] FIG. 4(a) shows a narrow width W R1 FIG. 2 is an explanatory diagram of the opening degree of the car determined when the moving body 30c of the car gets on. In this case, the car door 132B opens by two plates moving in the left and right directions from the center. Therefore, the car opening degree determination unit 224B is set to, for example, the width W of the left half of the opening 131. D / 2 and the width W of the left half of the moving body 30 R1 Difference between / 2 and W D / 2 - W R1 It is determined whether / 2 is equal to or greater than 1 / 2 of the threshold value T2.

[0050] Here, the cage opening degree determination unit 224B is the width W of the left half of the opening 131. D / 2 and the width W of the left half of the moving body 30 R1 Difference between / 2 and W D / 2 - W R1 When it is determined that the threshold T2 is equal to or greater than 1 / 2 of the threshold T2, and the moving body 30c enters the elevator car 13B, the opening degree W R1 + α determines that car door 132B will be opened.

[0051] In step S3, when the cage opening degree determination unit 224B determines that the difference between the width of the opening 131 and the width of the moving body 30 is less than the threshold value T2, that is, the width W of the left half of the opening 131 is D / 2 and the width W of the left half of the moving body 30 R1 Difference between / 2 and W D / 2 - W R1 When it is determined that 1 / 2 is less than 1 / 2 of the threshold value T2 ("NO" in S3), the difference between the width of the opening 131 and the width of the moving body 30 is set to be equal to or greater than the threshold value T2, and it is determined that the car door 132B is opened at the normal opening angle, i.e., fully open, when the moving body 30 enters the car 13B (S5).

[0052] FIG. 4(b) shows a car door 132B with a wide width W R2 FIG. 2 is an explanatory diagram of the opening degree of the car determined when the moving body 30d of the elevator 1 gets on. In this case, the car opening degree determination unit 224B determines the opening degree of the car 131 by the width W D / 2 and the width W of the left half of the moving body 30 R1 Difference between / 2 and W D / 2 - W R1 It is determined that / 2 is less than 1 / 2 of the threshold value T2, and the difference between the width of the opening 131 and the width of the moving body 30 is less than the threshold value T2, and it is decided to fully open the car door 132B when the moving body 30c enters the car 13B.

[0053] The elevator control unit 222 moves the elevator car 13B to the boarding floor of the moving body 30 based on the call information of the moving body 30 registered in the call registration unit 221, and when the elevator car 13B lands at the boarding floor of the moving body 30, the door opening / closing control unit 225 opens the car door 132B at the opening degree determined by the car opening degree determination unit 224B (S6).

[0054] When the door of the car 13B opens, the operation control unit 332 of the moving body 30 controls the moving mechanism 32, so that the moving body 30 gets on the car 13B.

[0055] When the elevator control unit 222 detects that the moving body 30 has boarded the car 13B based on sensor information such as a camera device (not shown) or a load detection device (not shown) installed on the car 13B ("YES" in S7), it causes the door opening / closing control unit 225 to close the car door 132B and move the car 13B to the disembarking floor of the moving body 30 (S8).

[0056] Here, when a hall call for another moving body at the floor where the elevator 13B has arrived is registered in the call registration unit 221 ("YES" in S9), the dimension information acquisition unit 223 acquires information indicating the width of the other moving body (S10).

[0057] The cage opening determination unit 224B selects the wider moving body between the moving body 30 and another moving body (S11), returns to step S3, and determines whether the difference between the width of the opening 131 and the width of the selected moving body 30 is greater than or equal to the threshold value T2 (S3).

[0058] Then, depending on the judgment result, the opening degree of the car door 132B is determined by processing in step S4 or S5, and when the car 13B lands at the disembarking floor of the moving body 30, the door opening / closing control unit 225 opens the car door 132B at the determined opening degree (S6).

[0059] When the door of the car 13B opens, the operation control unit 332 of the moving body 30 controls the moving mechanism 32 so that the moving body 30 gets off the car 13B, and then another moving body gets on.

[0060] In step S9, when no hall call for another moving body is registered in the call registration unit 221 ("NO" in S9), the car opening determination unit 224B determines that the car door 132B is to be opened in the fully open state when the moving body 30 disembarks (S12).

[0061] When the car 13B is fully opened (S13), the operation control unit 332 of the moving body 30 controls the movement mechanism 32, so that the moving body 30 gets off from the car 13B. When the moving body 30 gets off from the car 13B ("YES" in S14), the process returns to step S1.

[0062] According to the above second embodiment, when a moving object boards an elevator having a car whose doors open to the left and right, if the width of the moving object is smaller than the width of the opening of the car by a predetermined value or more, the car doors are opened with as narrow an opening as possible while allowing the moving object to board, thereby preventing users at the landing from boarding the car together with the moving object.

[0063] In the above-described second embodiment, when a plurality of moving bodies simultaneously enter the car 13B, the dimension information acquisition unit 223 may acquire the dimension information of the plurality of moving bodies, and the car opening degree determination unit 224B may determine the opening degree of the car door 132B by determining whether or not the difference between the width of the moving body with the largest dimension information, specifically the widest moving body, among the plurality of moving bodies, and the width of the opening 131 is equal to or greater than the threshold value T2. By performing the process in this manner, the plurality of moving bodies can reliably enter the car 13B with a single door opening operation.

[0064] In the first or second embodiment described above, when the moving body 30 gets into the car 13A, 13B, the door opening / closing control unit 225 may analyze the image information captured by the camera device 133 to monitor whether the car doors 132A, 132B have been opened to the opening degree determined by the car opening degree determination units 224A, 224B, and may stop the door opening operation when it is determined that the doors have been opened to the determined opening degree. By configuring in this way, the opening degree of the car doors 132A, 132B can be adjusted with high accuracy using the camera device, which is an existing facility.

[0065] In the above-described first or second embodiment, when the moving body 30 gets on the cars 13A and 13B, the elevator control unit 222 may turn off the arrival light (not shown), the floor indicator light (not shown), and the lights (not shown) in the cars 13A and 13B installed at the elevator hall, and output notification information notifying that the cars 13A and 13B are not available from an output device (not shown) installed at the hall. By performing the processing in this manner, a user at the hall recognizes that the elevators 10A and 10B are not available when the moving body 30 gets on the cars 13A and 13B, and avoids getting on the elevators, thereby preventing the user and the moving body 30 from getting on the cars 13A and 13B together.

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.
