Description

TECHNICAL FIELD

[0001] The present application relates to the field of elevators, in particular to a non-contact registration device for an elevator. BACKGROUND

[0002] In order to solve the problem of germ transmission caused by the contact operation of passengers on traditional contact type elevator buttons, a variety of non-contact buttons have appeared on the market. The principle of the existing non-contact buttons for elevators can be roughly classified into two categories:

[0003] 1) Based on shielding detection, i.e. a light emitter and a light receiver for detecting the light emitted by the light emitter are arranged in a plane at a certain distance in front of the operation screen, when a passenger operates the operation screen, the hand as the operation action executor will shield the light, and the light receiver will detect that the light is shielded to generate a corresponding operation signal. This type of non-contact button needs to be specially provided with a light emitter and a light receiver, and also has the disadvantages of relatively large volume, etc., and the application range is small;

[0004] 2) Based on the proximity effect of the hand as the operation action executor to the button when the passenger operates, i.e. when the hand as the operation action executor approaches the operated button during registration operation, a certain special effect (such as capacitance change) will be generated between the hand and the button, so that non-contact registration can be realized by detecting the change of the corresponding parameter corresponding to the special effect, such as when the detected capacitance is greater than the threshold value, it is the corresponding registration signal of the passenger registration. This type of non-contact registration method has been widely used in many fields including elevators.

[0005] JP2011-162307 proposes to temporarily register the button among the buttons whose distance to the object such as the hand of the operation disc user detected by the distance measuring unit is closest to the distance between the object and the button, and when the distance between all the buttons and the object exceeds a second threshold value which is farther than the first threshold value, the temporarily registered button is determined as a formal registration, and the destination floor registration corresponding to the formally registered button is performed.

[0006] CN202180088233.X addresses the drawback of the technical solution in JP2011-162307, which suffers from unavoidable disruptive or interfering calls (i.e., a user within proximity to an elevator button and performing a gesture may not actually intend to access the button). CN202180088233.X proposes that when the distance between the object the user is pointing at and the elevator button panel is within a distance threshold indicating the user's intention to activate a button, if the object's speed is greater than the threshold speed and its direction indicates the object is moving in the positive direction of the user's intended button activation, then the user's request to activate the button is registered. However, since this solution only registers the user's request to activate the button based on the magnitude and direction of the corresponding speed when the distance between the object and the elevator button panel is less than the distance threshold, it has the following drawbacks:

[0007] When the distance threshold is too small, if the corresponding moving speed is too fast, the object may not decelerate in time and may have already touched the elevator button panel when it stops moving.

[0008] When the distance threshold is too large, the direction of the object's movement may change significantly after an already registered user requests the activation button, corresponding to a new button, which may lead to an incorrect registration of the activation button request.

[0009] For elderly passengers or those with slow movement, their hand movement speed may be slow, and even when they touch the elevator button panel, their hand movement speed will not exceed the threshold speed.

[0010] Therefore, a technical problem is how to minimize the probability of passengers touching the elevator button panel while registering the activation request by operating the elevator button panel, while ensuring the accuracy of the registration results. Summary of the Invention

[0030] Beneficial technical effects

[0031] The non-contact registration device for elevator disclosed in the application can minimize the probability of passengers touching the elevator button panel during the process of registering the activation button request by operating the elevator button panel while ensuring the accuracy of the registration result. DETAILED DESCRIPTION

[0032] In the embodiments 1 and subsequent embodiments, the operation screen can be an in-car destination registration device or a landing registration device configured with physical buttons and a distance detector, or an in-car destination registration device or a landing registration device configured with virtual buttons and having a function of detecting the distance between the operation body and the operation screen. The non-contact registration device for elevator of the present disclosure is not limited to the specific implementation of the operation screen and the buttons.

[0033] In the embodiments, the non-contact registration device for elevator comprises:

[0034] an operation screen for presenting the prompting information required when the passenger performs the registration operation;

[0035] a detector for detecting the distance between the operation body and the operation screen when the passenger performs the non-contact operation;

[0036] a memory for storing a first distance value and a second distance value, and the first distance value is greater than the second distance value;

[0037] a determination unit for determining the registration time according to the distance output by the detector and the first distance and the second distance, wherein the registration time is the time for generating the registration signal corresponding to the registration operation of the passenger;

[0038] a registration unit for generating the registration signal corresponding to the registration operation of the passenger according to the registration time.

[0039] Embodiment 2: The embodiment 2 is based on the embodiment 1 and details the way of determining the registration time by the determination unit.

[0040] When the distance is between the first distance and the second distance, the determination unit determines the movement of the operation body of the passenger according to the distance and determines the registration time according to the movement; when the distance is less than or equal to the second distance, the determination unit takes the time when the distance changes from greater than the second distance to less than or equal to the second distance as the registration time.

[0041] Specifically, the movement includes at least one of the moving speed or the change thereof, the moving direction or the change thereof, and the moving track of the operation body (for example, when the passenger's hand except the index finger is closed and the index finger is used for operation, the operation body is the index finger or the tip of the index finger of the passenger's hand); and the determination unit determines the registration time in any of the following ways:

[0042] 1) determining the moving speed of the passenger's operating part or the change thereof according to the distance, and taking the time when the moving speed of the passenger's operating part or the change thereof changes from being greater than a first threshold value to being less than or equal to the first threshold value as the registration time;

[0043] 2) determining the moving direction of the passenger's operating part or the change thereof according to the distance, and taking the time when the moving direction of the passenger's operating part or the change thereof changes from being greater than a first threshold value to being less than or equal to the first threshold value as the registration time.

[0044] 3) determining the moving track of the passenger's operating part according to the distance, and taking the time when the angle between the moving track and the operation screen is greater than a second threshold value or the rate of change of the angle is less than a third threshold value as the registration time.

[0045] Preferably, the first distance is the maximum detection distance of the detector or a distance slightly less than the maximum detection distance of the detector.

[0046] From the above, it can be seen that the non-contact registration device for elevators of the present embodiment registers the registration signal of the registration operation of the passenger, including the following cases:

[0047] If the minimum distance between the operating body of the passenger (such as the tip of the index finger of the hand) and the operation screen is always greater than the second distance, the non-contact registration device for elevators completes the registration of the registration signal according to the operation of the operating body between the first distance and the second distance.

[0048] If the minimum distance between the operating body of the passenger (such as the tip of the index finger of the hand) and the operation screen is less than the second distance, i.e., the tip of the index finger of the hand of the passenger enters the position at the second distance and is between the operation screen, the non-contact registration device for elevators registers the registration signal of the passenger when the tip of the index finger of the hand reaches the position at the second distance.

[0049] For the non-contact registration device, if when the determining part determines that there is at least one first time when the operating body is between the first distance and the second distance, at the first time, the determining part determines that the condition in at least one of the above-mentioned ways of determining the registration time is met, the determining part determines the registration time when the operating body is between the first distance and the second distance. When the operating body continues to approach the operation screen after the determining part determines the registration time, the following processing mode is preferably present:

[0050] When the second condition is met, the determining unit continues to monitor the distance until the distance is no longer reduced or equal to the second distance, and generates a new registration time point after the new registration time point and sends it to the registration unit; when the registration unit receives the new registration time point after the new registration time point, the registration unit generates a registration signal according to the operation point corresponding to the operation body at the new registration time point (for the button in this embodiment, the operation point here is the button corresponding to the operation body at the new registration time point, which is taken as the target button by the registration unit). The second condition includes:

[0051] Condition A, the registration time point has been determined at the first time point, and the first time point is a time point at which the distance is between the first distance and the second distance;

[0052] Condition B, it is monitored that the distance continues to decrease after the first time point.

[0053] According to the sending of the previous registration time point by the determining unit and the way of generating the registration signal by the registration unit, the above processing mode is specifically divided into two cases:

[0054] Case 1, the determining unit sends the registration time point to the registration unit immediately after determining the registration time point, and then continues to monitor the distance until the distance is no longer reduced or equal to the second distance, and sends the time point corresponding to the minimum distance or the time point when the distance is equal to the second distance to the registration unit as a new registration time point after the new registration time point. The registration unit generates a registration signal according to the button corresponding to the operation body at the new registration time point as the target button. At this time, the previous registration time point only plays an enabling role for the registration unit. If there is no enabling effect of the previous registration time point, if the movement corresponding to the registration time point after the new registration time point does not meet the conditions in the way of determining the registration time point by the determining unit, it may not be possible to register the registration signal of the passenger because the distance is far away from the operation screen before reaching the second position.

[0055] Case 2, the determining unit records the registration time point after determining the registration time point but does not send it to the registration unit, and then the determining unit continues to monitor the distance until the distance is no longer reduced or equal to the second distance, and generates a new registration time point after the new registration time point (the new registration time point at this time is only an enabling signal, so it does not necessarily include the time point corresponding to the minimum distance or the time point when the distance is equal to the second distance) and sends it to the registration unit. The registration unit only generates a registration signal according to the button corresponding to the operation body at the new registration time point as the target button when it receives the new registration time point after the new registration time point.

[0056] It should be noted that in some specific cases, the aforementioned prior registration time may coincide with the subsequent new registration time (if the movement of the operating body does not satisfy the condition in the manner in which the registration time is determined by the determination unit after the first time the condition is satisfied, and the operating screen is no longer approached), at which time the prior registration time can be used as the subsequent new registration time.

[0057] Embodiment 3: This embodiment is further described on the basis of any of the preceding embodiments.

[0058] In this embodiment, the non-contact registration device for elevators further comprises:

[0059] The control unit is configured to control the presentation mode of the operating screen for the prompt information according to the distance and the first distance and the second distance.

[0060] Under the control of the control unit, the presentation characteristics of the operating screen when presenting the prompt information when the distance is less than or equal to the second distance are different from the presentation characteristics of the operating screen when presenting the prompt information when the distance is between the first distance and the second distance, and the presentation characteristics include brightness and / or color when presenting.

[0061] Under the control of the control unit, the operating screen presents the prompt information with a variable first brightness when the distance is between the first distance and the second distance; the operating screen presents the prompt information with a fixed second brightness when the distance is less than or equal to the second distance; and the brightness difference between the first brightness and the second brightness is a monotonic decreasing function of the difference between the distance and the second distance.

[0062] Under the control of the control unit, the operating screen presents the prompt information with a variable first color when the distance is between the first distance and the second distance; and the color element difference between the first color and the second color is a monotonic decreasing function of the difference between the distance and the second distance, the color element including at least one of hue, chroma, lightness, and saturation.

[0063] Under the control of the control unit, the operating screen presents the prompt information in a first color and a second color alternately when the distance is between the first distance and the second distance; the operating screen presents the prompt information with the second color when the distance is less than or equal to the second distance; and in the alternating manner, the ratio of the presentation time of the second color to the presentation time of the first color is a monotonic increasing function of the difference between the distance and the second distance.

[0064] If the minimum distance is greater than the second distance after the distance reaches the minimum, the control section calculates a difference between the presentation feature of the presentation mode corresponding to the minimum distance and the presentation feature of the presentation mode when the distance is less than or equal to the second distance, and sets an excess section of a given time length or less based on the difference, so that the presentation feature is gradually transitioned from the presentation feature of the presentation mode corresponding to the minimum distance to the presentation feature of the presentation mode when the distance is less than or equal to the second distance.

[0065] In a second process in which the distance gradually increases due to the passenger operation section gradually moving away from the operation screen after the distance reaches the minimum, the control section maintains control so that the operation screen presents the prompting information in accordance with the presentation feature of the presentation mode corresponding to the minimum distance or in accordance with the presentation feature of the presentation mode when the distance is less than or equal to the second distance.
