Description

TECHNICAL FIELD

[0001] The present application relates to the field of elevators, in particular to an elevator destination registration system. BACKGROUND

[0002] Currently, elevator systems will provide a destination registration device for passengers to register destination floor information in the car. The destination registration device usually contains multiple destination floor buttons corresponding to each floor of the building where the elevator is located. Passengers register the destination floor by operating these destination floor buttons, and these destination floor buttons are arranged on a plane. The destination registration device can be either a touch screen based on virtual buttons or a traditional control box based on mechanical buttons. Due to the need to avoid the spread of viruses, traditional control boxes based on non-touch buttons are gradually increasing, but whether it is a touch screen based on virtual buttons or a traditional control box based on non-contact buttons, there is a phenomenon that passengers accidentally register multiple destination floors, including both the real destination floor of the passenger and the non-real destination floor. Therefore, the destination registration device needs to identify the real destination floor registered by the passenger from the destination floors registered by the passenger.

[0003] To solve the above problems, CN202211276918.X proposes to only take the upper buttons among the multiple buttons arranged in the up-down direction as the buttons corresponding to the real destination floor of the passenger. However, this processing method has obvious defects: 1) it cannot handle the scenario where the simultaneously registered buttons are horizontally arranged; 2) when the number of destination floor buttons is large enough to make the height of some destination floor buttons lower than the elbow height of the passenger, the passenger's hand is pointing downward when registering the destination floor. At this time, if there are multiple buttons that are simultaneously registered and arranged in the up-down direction, the lower buttons correspond to the real destination floor of the passenger, so the registration result will be incorrect.

[0004] Therefore, how to correctly identify the button corresponding to the real destination floor of the passenger when the passenger simultaneously registers multiple destination floor buttons has become a technical problem to be solved. SUMMARY

[0005] The technical problem to be solved by the present application is how to correctly identify the button corresponding to the real destination floor of the passenger when the passenger simultaneously registers multiple destination floor buttons.

DETAILED DESCRIPTION

[0030] The present application will be further described in detail below in conjunction with the specific embodiments.

[0031] Embodiment 1

[0032] The present embodiment provides an elevator destination registration system, comprising: a plurality of destination buttons, an identification module, a direction determining module, a button determining module, and a sending module.

[0033] The destination floor button is composed of a plurality of units, which are the minimum units that can be identified whether they are subjected to the registration operation from the elevator user; the destination floor button corresponds to each floor of the building where the elevator is located, and is used to receive the registration operation performed by the elevator user for registering the destination floor; each destination floor button is generally distributed in the same plane;

[0034] The identification module determines the first unit subjected to the registration operation according to the registration operation of the elevator user, and further identifies a specific unit group consisting of the first unit subjected to the registration operation by the elevator user;

[0035] The direction determination module determines the hand direction of the elevator user when performing the registration operation according to the specific unit group;

[0036] The button determination module determines the second button according to the hand direction and the first unit, the second button being the destination floor button that the elevator user actually wants to perform the registration operation on;

[0037] The sending module is configured to send the destination floor signal corresponding to the second button to the elevator control system.

[0038] The identification module identifies the specific button group according to the following rules:

[0039] When a unit group contains at least two first units, and the time interval between the operation time of any two first units in the unit group subjected to the registration operation by the elevator user does not exceed the time threshold, the identification module identifies all the first units in the unit group as subjected to the registration operation by the elevator user at the same time, and identifies the unit group as a specific unit group.

[0040] It should be noted that the elevator destination floor registration system of the present application is applicable to both the traditional mechanical button configured in the elevator car (of course, it is usually configured with a non-contact button, because the traditional press button generally does not have the misregistration phenomenon) and the touch screen type elevator car destination floor registration device (the button is actually a virtual button displayed on the touch screen) widely used in recent years.

[0041] It should be noted that the present application is mainly aimed at the situation that the passenger registers the real destination floor when registering the destination floor, and also misregisters other non-real destination floors due to some reasons. For the scene without misregistration, the identification module only needs to identify the only first button, but does not need to further identify the specific button group, the direction determination module does not need to perform any processing, and the button determination module takes the only first button as the second button. The following will only be described for the scene with misregistration.

[0042] Embodiment 2

[0043] This embodiment is further elaboration of the elevator destination registration system of the present application based on Embodiment 1.

[0044] This embodiment is directed to the elevator destination registration system of the virtual button displayed on the touch screen.

[0045] The direction determining module determines the figure of the specific group of monomers according to the position information of the first monomers, and determines the hand direction of the elevator user when performing the registration operation according to the figure of the specific group of monomers.

[0046] The button determining module first determines the destination floor button located in the figure of the specific group of monomers according to the figure of the specific group of monomers, then determines the position of the end of the finger of the elevator user when performing the registration operation according to the hand direction and the figure of the specific group of monomers, and finally determines the destination floor button corresponding to the position of the end of the finger in the destination floor button located in the figure of the specific group of monomers, and takes it as the second button.

[0047] The direction determining module determines the contour line of the specific group of monomers according to the position information of the first monomers, and determines the destination floor button located in the figure of the specific group of monomers according to the contour line and the pre-stored position information of the destination floor button. The method for determining the contour line of the specific group of buttons by the direction determining module is as follows: first, determining the boundary monomers in the first monomers, and then connecting the boundary monomers in sequence according to the adjacent relationship of the boundary monomers to obtain the contour line of the specific group of buttons; when the number of first monomers adjacent to a certain first monomer is less than a preset value (for example, 4), the first monomer is identified as a boundary monomer.

[0048] The button determining module determines the position of the end of the finger in the following manner: first, image recognition is performed on the figure of the specific group of monomers, then the second position of any part of the finger of the elevator user when performing the registration operation is determined by using the image recognition result and the hand direction, then the straight line where the finger of the elevator user is located when performing the registration operation is determined by using the second position and the hand direction, and finally the intersection point of the straight line where the finger is located and the contour line of the figure is determined, and the intersection point is determined as the position of the end of the finger.

[0049] The technical solution of this embodiment is described in detail below with an example.

[0050] Example 1, a certain elevator car is provided with a control box, on the control box is provided with a touch display screen, the display screen displays the destination floor buttons corresponding to each floor of the building where the elevator is located, the passenger can register the destination floor information by clicking the destination floor button, the destination floor information will be sent to the elevator control system. Obviously, these destination floor buttons are distributed on the plane of the display screen.

[0051] Now assume that an elderly passenger, because of the slight shaking of his hands, almost the entire palm touches the touch display screen when registering the destination floor. For the touch display screen, it is composed of many small units with display function and receiving touch operation and generating a signal in response to the touch operation, a button usually contains many such units. Therefore, for such operation of the elderly passenger, the projection of the elderly passenger's hand on the touch screen will cover most of the units (because the palm and fingers usually have a certain degree of curvature, so even if the hand is placed on the touch screen, the middle of the palm and the middle of the fingers will not touch the touch screen) will be touched, and these touched units will generate and output operation signals indicating that they are touched.

[0052] The recognition module determines the destination floor buttons corresponding to the touched units according to the pre-stored unit position information, and then according to the operation time of the touched unit (in fact, it is difficult to directly obtain the operation time, but in the case of ignoring the transmission time of the operation signal from the unit to the recognition module, the reception time of the recognition module receiving the operation signal can be approximately regarded as the operation time), the recognition module identifies the specific button group according to the above rule.

[0053] The direction determination module determines the pattern of the specific unit group according to the pre-stored unit position information, and by image recognition of the image, the approximate shape of the elderly passenger's hand can be obtained. Considering that in general cases, the passenger implements the registration operation by stretching a finger (mostly the index finger), and the rest of the fingers are in a fist shape, therefore the result of image recognition is mostly the edge of the palm, small fingers, thumbs, etc., according to these information, the direction of the elderly passenger's hand when registering the destination floor can be easily determined. The button determination module also performs image recognition on the image or borrows the image recognition result of the direction determination module, and determines the end of the finger (here, the index finger) stretched by the passenger when implementing the registration operation (since the middle of the stretched finger must not touch the touch screen, only the end can touch the touch screen, so it appears as an independent point away from the rest (the edge of the palm, small fingers, thumbs, etc.)), in this way, combined with the direction of the hand and the image recognition result, the end of the finger can be determined, and the button determination module takes the first button corresponding to the position of the end of the finger as the second button.

[0054] It should be noted that the technical solution of the embodiment is applicable to a scenario in which the number of touched monomers is sufficient for the passenger to implement the registration operation so as to obtain the approximate figure of the hand through image recognition.

[0055] Embodiment 3

[0056] The embodiment is similar to Embodiment 2, and only the differences will be described below.

[0057] In the embodiment, the button determining module determines the finger end position in any of the following manners: determining a first point corresponding to the most protruding point on the contour line relative to the hand direction as the finger end position, and determining the first button corresponding to the finger end position as the second button.

[0058] In Example 2, which continues Example 1, the direction determining module determines the overall contour line of the specific button group composed of the touched monomers according to the pre-stored monomer position information, and determines the approximate hand direction of the old passenger when implementing the registration operation according to the overall contour line, and the button determining module determines a first point corresponding to the most protruding point on the contour line relative to the hand direction as the finger end position.

[0059] The technical solution of the embodiment has a lower number and position distribution of the touched monomers relative to Embodiment 2, because only the contour line and the hand direction are required in the embodiment, and therefore the touched monomers inside the contour line are basically not required (because only a contour line is required to determine the hand direction; when determining the contour line, only a small number of touched monomers approximately located on the contour line are required).

[0060] Embodiment 4

[0061] The embodiment and subsequent embodiments are all directed to the elevator control box configured with traditional mechanical buttons and non-contact buttons. These buttons are usually distributed on the surface of the elevator control box. Since they are non-contact buttons, when the passenger operates improperly, the misregistration phenomenon may occur, and therefore the scheme of the application can be used to identify the destination floor button from the registration result containing the real destination floor button and the misregistered non-real destination floor button, and register the destination floor signal of the real destination floor button.

[0062] The embodiment provides an elevator destination floor registration system, which comprises: a plurality of destination floor buttons, an identification module, a direction determining module, a button determining module, and a sending module.

[0067] The sending module is configured to send a destination floor signal corresponding to the second button to the elevator control system.

[0068] The identification module identifies the specific button group according to the following rules:

[0069] When a button group contains at least two first buttons, and the time interval between the operation time of any two first buttons in the button group is not more than a time threshold, the identification module determines that all the first buttons in the button group are simultaneously registered by the elevator user, and identifies the button group as the specific button group.

[0070] The direction determination module determines the first position of the first buttons on the plane according to the pre-stored position information of the elevator buttons, and determines the hand direction of the elevator user when the registration operation is performed according to the first position corresponding to each first button; the button determination module determines the first button located at the front of the hand direction as the second button.

[0071] The direction determination module determines the first position of the specific button group on the plane according to the position of each first button constituting the specific button group on the plane, determines the first height of the specific button group relative to the car floor according to the first position and the pre-stored height of the plane relative to the car floor, and determines the hand direction of the elevator user when the registration operation is performed according to the first height.

[0072] When the first height exceeds a first height threshold, the direction determination module determines the hand direction as upward;

[0073] When the first height is less than a second height threshold, the direction determination module determines the hand direction as downward;

[0074] When the first height is between the second height threshold and the first height threshold, the direction determination module determines the hand direction as substantially horizontal.

[0075] When the hand direction is upward, the button determining module determines the highest first button among the first buttons constituting the specific button group as the second button;

[0076] When the hand direction is downward, the button determining module determines the lowest first button among the first buttons constituting the specific button group as the second button;

[0077] When the hand direction is substantially horizontal, the button determining module determines the first button closest to the car side wall among the first buttons constituting the specific button group as the second button.

[0078] Embodiment 5

[0079] This embodiment is similar to Embodiment 4, and only the differences will be described below.

[0080] In this embodiment, the elevator destination registration system further comprises a first detection body for detecting the position of the elevator user;

[0081] The direction determining module determines the hand direction of the elevator user when performing the registration operation according to the first height and the position of the elevator user.

[0082] The direction determining module determines the relative position of the elevator user in the horizontal direction with respect to the plane (i.e., whether the elevator user (strictly speaking, the right arm of the elevator user) is on the left side or the right side of the registration interface) according to the position of the elevator user, and then obtains the hand direction as right-up, right-down, left-down, left-up, etc. according to the combination of the relative position and the relationship between the first height and the first height threshold value and the second height threshold value in Embodiment 4, and then determines the hand direction of the elevator user when performing the registration operation; the button determining module determines the first button located in the front of the hand direction as the second button.

[0083] As for the first detection body, it can be recognition according to the video image in the car, or it can be based on the sensor arranged under the car floor, and this embodiment does not limit it.

[0087] The direction determining module determines the first height threshold value and the second height threshold value according to the height of the elevator user or the elbow thereof.

[0088] For example, the height of the elbow is added with a certain amount Δh1 as the first height threshold, and the height of the elbow is subtracted with a certain amount Δh2 as the second height threshold. The first height threshold and the second height threshold thus determined are more accurate, and therefore the hand direction determined according to the same is also more correct.

[0089] For the second detection body, it can be a video image recognition in the car (directly recognizing the height, or recognizing the identity, and then determining the height of the elevator user or the elbow thereof according to the pre-stored corresponding relationship between the identity and the height), or a light curtain sensor arranged at the car door, which is not limited in the embodiment.

[0093] The direction determination module determines the first height threshold and the second height threshold according to the height of the elevator user or the elbow thereof, and the position of the elevator user, so that the included angle between the line connecting the elbow of the elevator user and the specific button group and the plane is greater than the angle threshold.

[0094] The present application has been described in detail through specific embodiments and examples, but these do not constitute a limitation on the present application. Those skilled in the art can also make many modifications and improvements without departing from the principles of the present application, and these should also be considered as falling within the protection scope of the present application.
