Description

[Technical field]

[0001] An embodiment of the present invention relates to a system and a method for preventing the use of a trolley in an elevator. [Background technology]

[0002] Recently, the use of elevator carts has increased in office buildings and apartment buildings due to the increase in home delivery packages. When a person using a cart tries to use a general elevator, the cart may collide with the landing door or jamb, causing scratches and damage.

[0003] In response to this, building managers have taken into consideration the possibility of damage to the car floor and side panels and have put up warning posters prohibiting the use of passenger elevators for carts and encouraging the use of elevators for passengers and freight. However, these rules are not being followed, especially when there are no passengers.

[0004] On the other hand, there are also known examples of grasping the status of a hall using image recognition. There is an elevator boarding detection system that uses image recognition to detect the presence or absence of passengers who intend to board an elevator. [Prior art documents] [Patent documents]

[0010] Hereinafter, an elevator cart usage prevention system and an elevator cart usage prevention method according to the present invention will be described with reference to the drawings.

[0011] First Embodiment FIG. 1 shows an example of acquiring image information around an entrance door.

[0012] As shown in FIG. 1, near the landing door 2 of the landing 1, there are installed a landing operation panel (landing destination floor button) 3 for registering landing calls, a camera 4 for taking images of the area around the landing 1, and a speaker 5 for announcing audio guidance at the landing 1.

[0013] An in-car operation panel 6 is installed inside the car, and a user inside the car registers a destination floor call. In this embodiment, a trolley use prevention switch 8 is installed inside a switch box 7. When this trolley use prevention switch 8 is turned on, a user 9 is restricted from using a trolley 10 to use the elevator.

[0014] FIG. 2 shows a system configuration of the first embodiment.

[0015] As shown in Fig. 2, elevator control device 20, which controls the running of general elevators, is connected to a hall operating panel (or a hall destination floor registration device or a hall destination floor button) 3, a camera 4, a speaker 5, an in-car operating panel 6, and a trolley use prevention switch 8. Also, a passenger / freight elevator control device 30, which controls the running of a passenger / freight elevator used by a user 9 on a trolley 10, is connected to a passenger / freight hall call button 15 (see Fig. 8). The running control of passenger / freight elevator control device 30 is basically the same as that of elevator control device 20, so a description thereof will be omitted.

[0016] The elevator control device 20 includes a call registration unit 21, a travel control unit 22, a camera image input unit 23, a cart user recognition unit 24, an alarm unit 25, a switch information input unit 26, and a hall call release unit 27.

[0017] The call registration unit 21 registers hall calls from the hall operating panel 3 and car calls from the car operating panel 6.

[0018] The running control unit 22 controls the running of the elevator car based on the hall calls and elevator car calls registered in the call registration unit 21.

[0019] The camera image input unit 23 inputs image information captured by the camera 4 .

[0020] The trolley user recognition unit 24 analyzes the input image information and recognizes whether or not a trolley user is present at the hall 1 .

[0021] The notification unit 25 issues an announcement to users 9 of the cart 1 via a speaker 5 installed at the hall 1 .

[0022] The switch information input unit 26 inputs switch information when the trolley use prevention switch 8 is turned on.

[0023] When the cart use prevention switch 8 is turned on, if the user 9 of the cart 10 is recognized, the hall call cancellation unit 27 cancels the hall call registration.

[0024] FIG. 3 is a flowchart showing the process of the trolley use prevention system of the first embodiment.

[0025] 3, first, it is determined whether the trolley use prevention switch 8 is ON (enabled) or not (step S1). When the trolley use prevention switch 8 is enabled and a call registration for a car of a general elevator (general elevator) is performed (step S2), image information of the vicinity of the entrance door is acquired by the camera 4 (step S3). The acquired image information is input to the camera image input unit 23.

[0026] Next, the trolley user recognition unit 24 analyzes the image information acquired in step S3, and analyzes whether or not a user 9 using the trolley 10 is present within a certain range in front of the hall operating panel 3 at the hall 1 of the general elevator (step S4). If it is determined that the trolley 10 is present within the certain range as a result of the analysis, the notification unit 25 notifies the user 9 at the hall 1 of the use of the passenger / freight elevator and the announcement of the cancellation of the call registration of the general elevator via the speaker 5 (step S5). Then, the hall call cancellation unit 27 cancels the call registration of the general elevator (step S6). If the call registration of the car of the general elevator is performed again within a certain time after the call registration is cancelled (step S7), normal operation control is restored (step S8).

[0027] Thus, according to the first embodiment, it is possible to prevent the user 9 of the cart 10 from using a general elevator, and to prevent damage to the elevator jamb, entrance door, and car interior design due to contact with the cart 10. Furthermore, although there is a possibility that a stroller may be mistaken for the cart 10 during image analysis in step S4, when the call registration is performed again (step S7), it is possible to prevent a situation in which the stroller user is unable to use a general elevator by returning to normal operation control.

[0028] <Second embodiment> Next, a second embodiment of the present invention will be described.

[0029] The feature of the second embodiment is that it is possible to analyze the damaged areas from image information acquired from a camera 4 installed in the elevator hall, and list the damaged areas and their heights, thereby restricting the use of general elevators to only those users who are more likely to cause damage.

[0030] For this reason, the system configuration in FIG. 4 is configured to include a damage location analysis unit 28 and an analysis result storage unit 29 in addition to the system configuration in FIG.

[0031] The damaged part analysis unit 28 analyzes whether or not there is a damaged part based on the image information input to the camera image input unit 23. Specifically, as shown in Fig. 5, the camera 4 periodically captures images to determine whether or not there is a damaged part 12 in the landing door 2 or the jamb 11, and acquires image information to identify the damaged part. The example in Fig. 5 shows that there is a scratch (damaged part 31) 200 mm above the floor of the landing door 2.

[0032] The analysis result storage unit 29 lists and stores the damaged parts analyzed by the damaged part analysis unit 28. Specifically, as shown in Fig. 6, the damaged parts and the damage heights are listed and stored. If the damaged part is not registered in the damage part list shown in Fig. 6, the damaged part and the damage height are newly added to the list.

[0033] FIG. 7 is a flowchart showing a processing procedure according to the second embodiment.

[0034] First, the trolley use prevention switch 8 is enabled (step S11). After that, when a call for a general elevator car is registered (step S12), image information around the entrance door is acquired. The damage location analysis unit 28 analyzes the height of the trolley within a certain range in front of the hall operating panel (or hall call registration device) 3 of the hall 1 of the general elevator (step S13).

[0035] Next, it is determined whether or not there is a damaged part whose dimensions match the cart height analyzed in step S13 in the damaged part list in the analysis result storage unit 29. If there is a damaged part that matches (steps S13, S14 YES), an announcement is made to the user 9 of the cart 10 that the passenger / freight elevator will be used and that the call registration for the general elevator will be cancelled (step S15), and the call registration for the general elevator is cancelled (step S16). If a call registration for the general elevator car is made again within a certain period of time after the call registration is cancelled (step S17), normal operation control is restored (step S18).

[0036] Thus, according to the second embodiment, the damaged areas are analyzed from image information acquired from a camera installed in the elevator hall, and the damaged areas and heights are listed, thereby limiting the use of general elevators to users 9 who are more likely to cause damage.

[0037] <Third embodiment> Next, a third embodiment of the present invention will be described with reference to FIG.

[0038] The feature of the third embodiment is that a trolley user 9 entering the elevator hall can smoothly use the passenger / freight hall call button 15 without getting confused about which passenger / freight elevator to use, which results in preventing damage to elevator equipment caused by the use of a trolley.

[0039] 8 shows that a trolley user is entering the elevator hall, and this is recognized by a camera 41 installed near the entrance to the elevator hall. The camera 41 captures an image of the trolley 10 that is about to enter the elevator hall. An announcement is broadcast by a speaker 51 installed in the elevator hall.

[0040] The operation will be described with reference to the flowchart in Fig. 9. When the trolley use prevention switch 8 is enabled (step S21), and the camera 41 installed near the entrance to the elevator hall detects the entry of the trolley 10, it acquires image information, analyzes the image, and recognizes the height of the trolley (step S22).

[0041] Next, if there is a dimension matching the cart height in the damage location list in the analysis result storage unit 29 (YES in step S23), an announcement is made from the speaker 51 also installed in the elevator hall encouraging the use of the passenger / freight elevator (step S24). If no call is registered from the passenger / freight hall call button 15 within a certain time (step S25), the announcement to use the passenger / freight elevator is repeated once more (steps S24, S26).

[0042] In this way, according to the third embodiment, the damaged part is analyzed from the image information acquired from the camera 41, and the damaged part and height are listed. Therefore, it is possible to limit the use of general elevators to users 9 who are more likely to cause damage, and encourage them to use passenger / freight elevators.

[0043] <Fourth embodiment> Next, a fourth embodiment of the present invention will be described with reference to FIG.

[0044] The fourth embodiment is characterized in that, when a user 9 on a cart 10 is recognized while the door of a general elevator is open, an announcement is made that the user will be using the cargo elevator, and the door is forcibly closed.

[0045] FIG. 10 is a flowchart showing the process of the trolley use prevention system according to the fourth embodiment.

[0046] 10, it is determined whether the cart use prevention switch 8 is ON (enabled) or not (step S31). When the cart use prevention switch 8 is enabled and the car door is open, image information captured by the camera 4 is acquired (steps S32, S33). The acquired image information is input to the camera image input unit 23.

[0047] Next, the trolley user recognition unit 24 analyzes the image information acquired in step S33, and analyzes whether or not a user 9 using the trolley 10 is present within a certain range in front of the hall operating panel 3 at the general elevator hall 1 (step S34). If it is determined as a result of the analysis that the trolley 10 is present within the certain range, the notification unit 25 notifies the user 9 at the hall 1 via the speaker 5 that a passenger / freight elevator will be used, and forcibly closes the door (step S35). If a call registration for a general elevator car is performed again within a certain time after the call registration is cancelled (step S36), normal operation control is restored (step S37).

[0048] Thus, according to the fourth embodiment, while the doors are open, an announcement is made via the speaker 5 to the effect that the passenger / freight elevator will be used before the user 9 of the cart 10 gets into the car, and the doors are forcibly closed. Therefore, as in the first embodiment, it is possible to prevent the user 9 of the cart 10 from using the general elevator, and it is possible to prevent damage to the elevator jamb, entrance door, and car interior design due to contact with the cart 10.

[0049] The present invention is not limited to the above-mentioned embodiments, and various modifications can be made without departing from the spirit of the present invention. For example, the camera 4 for image analysis installed around the entrance door may be a so-called smart camera installed inside the car, and the object of image analysis may be the side panel of the car or the entrance door of the car.

[0050] In addition, if it is detected in a specified area of ​​the image information acquired by the camera 4 that a user 9 on the trolley 10 is attempting to enter the car of a general elevator, an announcement may be made urging the user 9 to exit the car of the general elevator.

[0051] In addition, if image analysis reveals that the person is a trolley user, the car call registration may not be cancelled, but rather an announcement may simply be made to warn the person.

[0052] Although several embodiments of the present invention have been described above, 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. These embodiments and their modifications are included in the scope and spirit of the invention, and are included in the scope of the invention and its equivalents described in the claims.
