Description

TECHNICAL FIELD

[0001] The present application relates to the elevator technical field, and particularly relates to an elevator information input system. BACKGROUND

[0002] In order to facilitate the disabled passengers with wheelchairs, the elevator is provided with a disabled operation box on the side wall of one side of the car, and the height of the disabled operation box is equivalent to the height of the wheelchair passenger, so that the wheelchair passenger can register the destination floor by operating the disabled operation box. However, since one elevator is usually provided with only one disabled operation box and located on the side wall of one side of the car, before entering the car, the wheelchair passenger may not know where the disabled operation box is located. When entering the car, the wheelchair passenger finds that the disabled operation box is located on the side far away from the wheelchair passenger and the wheelchair passenger cannot reach the disabled operation box. At this time, the wheelchair passenger needs to adjust the position of the wheelchair to shorten the distance between the wheelchair and the disabled operation box. Obviously, this brings inconvenience to the wheelchair passenger, and in the adjusting process, the wheelchair passenger may also affect other passengers in the car. In addition, the wheelchair passenger may not be able to register the destination floor by moving to the position close to the disabled operation box due to the fact that the other passengers standing beside the disabled operation box do not notice. At this time, the wheelchair passenger may need to remind the other passengers standing beside the disabled operation box to avoid or ask them to register the destination floor.

[0003] In view of this problem, CN201510272692.X proposes that a plurality of touch panel displays are arranged on the side wall and the back wall of the car. After detecting the wheelchair passenger, the touch panel displays are controlled according to the position of the wheelchair passenger, so that one of the plurality of touch panel displays displays the car operation panel picture for the wheelchair passenger to operate.

[0004] The above-mentioned prior art can facilitate the operation of the wheelchair passenger to a certain extent, such as increasing the selectivity of the wheelchair passenger to implement the registration operation. However, there are still some shortcomings: 1) the position of the wheelchair passenger is limited, that is, the wheelchair passenger still needs to move to the position close to the side wall or the back wall; 2) the plurality of touch panel displays affect the appearance and increase the complexity of the system, such as power supply, installation and fixation, wire harness planning, information transmission, etc. On the other hand, the cost is also increased because the touch panel displays cannot be reused, and one touch panel display can only be used in one fixed position.

[0005] In fact, in addition to the wheelchair passenger, some other special passengers may encounter similar problems as the wheelchair passenger, such as the passengers with small stature (primary school students) who may not be able to reach the buttons located on the upper part when the number of buttons on both sides is large, thereby causing difficulty in taking the elevator.

[0024] Example 1

[0025] As shown in Figure 1 The present embodiment provides an elevator information input system, comprising:

[0026] A first detection device for detecting second information required for determining whether an enabling condition is met, the enabling condition being used to determine whether to enable an imaging device;

[0027] A first determination device for determining whether the enabling condition is met according to the second information; The first detection device can be any device capable of recognizing passenger features, such as car door light curtain, camera and image recognition device, etc.

[0028] A control device for controlling the imaging device to provide an input interface for passengers and receive first information input by passengers through operation of the input interface when the first determination device determines that the enabling condition is met;

[0029] An imaging device, which is an interactive space imaging device, is used to provide an input interface for passengers and receive first information input by passengers through operation of the input interface under the control of the control device.

[0030] The activation conditions include at least one of the following:

[0031] Condition 1: A passenger enters the elevator car;

[0032] Condition 2: Special passengers with specific needs for elevator information input enter the elevator car;

[0033] Condition 3: There are factors that affect passengers' use of other information input devices in the car that are different from the imaging device.

[0034] The first determination device determines whether a passenger entering the elevator car is a special passenger with special needs through the following methods:

[0035] Method 1: When the difficulty of an elevator passenger inputting first information using an information input device different from the imaging device inside the elevator car is significantly higher than the difficulty of an ordinary passenger's operation, the first judgment device determines that the passenger entering the elevator car is a special passenger. The operational difficulty includes at least one of the following:

[0036] Difficulty 1: The body orientation adjustment required for passengers entering the elevator car to input first information into other information input devices inside the car that are different from the imaging device;

[0037] Challenge 2: The maximum distance a passenger's arm needs to cross when operating other information input devices inside the elevator car, different from the imaging device, to input the first information.

[0038] Method 2: When a passenger entering the elevator car meets any of the following conditions, the first determining device determines that the passenger entering the elevator car is a special passenger:

[0039] Condition A: The height is lower than that of a normal passenger and the height difference between the two exceeds the height threshold;

[0040] Condition B: The specific distance is longer than the specific distance for ordinary passengers and the excess value between the two exceeds a threshold. The specific distance refers to the maximum distance between the passenger's shoulder axis and the uppermost operating point of other information input devices in the car that are different from the imaging device.

[0041] Condition C: Impaired or slow mobility;

[0042] Condition D: Accompanied by auxiliary tools that help with the action.

[0043] Example 2

[0044] This embodiment further defines and explains the installation location of the imaging device based on embodiment 1.

[0045] The imaging device is fixed in its installation position inside the car by a fixing device; the control device controls the imaging device to provide an input interface for passengers at the imaging position and to receive the first information input by passengers through the operation input interface.

[0046] The installation location and the imaging location satisfy a location condition, which refers to the condition that enables the imaging device installed at the installation location to provide an input interface for the passenger at the imaging location and receive information input by the passenger through the input interface.

[0047] When the imaging device provides an input interface for the passenger at the imaging position, and the transmission of the emitted imaging light along the transmission path is not affected by external interference, the position condition is deemed to be met.

[0048] Typically, the imaging device is installed at a point on a preset straight line on the top panel of the car, the preset straight line being along the depth direction of the car, and the difference between the distance between the preset straight line and the left side wall and the distance between the preset straight line and the right side wall is less than a threshold.

[0049] Preferably, the imaging device is installed at any point within the projection of the imaging position domain onto the car roof, or at the projection of the imaging position onto the car roof.

[0050] Example 3

[0051] This embodiment further defines and explains the imaging position based on the aforementioned Embodiment 2. Depending on whether the imaging position is fixed, it can be divided into two cases: fixed position and variable position. This embodiment focuses on the case where the imaging position is preset and cannot be changed.

[0052] The imaging position is a pre-selected point in the imaging position domain, which is a set of all imaging positions; the installation position is a point that, when combined with any imaging position in the imaging position domain, makes the position condition true.

[0053] The control device estimates the movement path of the passenger entering the elevator car and determines the imaging position domain based on the movement path.

[0054] When multiple movement paths exist, the control device preferentially selects an unoccupied movement path from the estimated movement paths and determines the imaging position domain based on the unoccupied movement path. In this case, in order to determine whether each movement path is occupied, the elevator information input system also needs to include: a second detection device for detecting the occupancy status inside the car; the control device determines whether a point in the imaging position domain, or the perpendicular line segment between a point in the imaging position domain and the car floor, or the movement path connecting the projection point of the point in the imaging position domain onto the car floor and the car door is occupied based on the detection result of the second detection device.

[0055] For example, the movement path estimated by the control device is a straight line passing through the center of the car door width and along the car depth direction.

[0056] The control device preferentially selects an unoccupied point in the imaging position domain as the imaging position, or selects a first point in the imaging position domain as the imaging position, wherein the first point is an unoccupied point on the perpendicular line segment between the point and the car floor.

[0057] Alternatively, the control device preferably selects a second point from the imaging position domain as the imaging position, wherein the second point satisfies the following condition: in the movement path connecting the projection point of the point on the car floor and the car door, there is at least one unoccupied movement path.

[0058] In this way, the control device can first estimate the passenger's movement path into the elevator car, then determine the imaging position domain based on the movement path, and then select a position from the imaging position domain as the imaging position. In this embodiment, the imaging position domain and the spatial position of the imaging position are fixed after being determined.

[0059] This disclosure does not limit the method by which the control device determines the imaging position domain; two exemplary methods are given below.

[0060] First exemplary determination method

[0061] This exemplary determination method specifically includes the following steps: Step 1, select a section of the moving path located inside the car that is roughly straight and has a length not less than a length threshold, and the minimum distance between the endpoint of the selected path on the side passing through the car door and the car door is greater than the threshold.

[0062] Step 2: Extract a sub-plane from the vertical plane passing through the selected path. The vertical boundaries of the sub-plane in the derivative direction of the selected path are the first vertical line and the second vertical line where the two endpoints of the selected path are located. The horizontal boundaries are the first horizontal line in the vertical plane at a height of the first height from the car floor and the second horizontal line located above the first horizontal line and at a distance of the first distance from the first horizontal line.

[0063] Step 3: Move the subplane a second distance to the left and right along its perpendicular direction respectively;

[0064] Step 4: Take the plane where the sub-plane is located when it stops moving left as the first plane, and the plane where the sub-plane sits when it stops moving right as the second plane; take the planes that the first vertical line and the second vertical line pass through during the left and right movements as the third plane and the fourth plane, respectively; take the planes that the first horizontal line and the second horizontal line pass through during the left and right movements as the fifth plane and the sixth plane, respectively.

[0065] Step 5: The space enclosed by the first plane to the sixth plane is taken as the imaging position domain.

[0066] Obviously, the imaging position domain determined by this exemplary method is a three-dimensional space with a certain volume.

[0067] The second exemplary determination method

[0068] In this exemplary determination method, the imaging position domain is a plane located inside the car, parallel to the elevator car door, and at a distance of the third distance from the car door. The lower boundary of the plane is a straight line within the plane at a distance of the fourth distance from the car floor, the upper boundary is a straight line within the plane located above the lower boundary and at a distance of the fifth distance from the lower boundary, and the left and right boundaries are straight lines within the plane at a distance of the sixth distance from the left and right side walls of the car, respectively.

[0069] As can be seen from the above description, the imaging position is a pre-selected point within the imaging position domain. Therefore, once the imaging position domain is determined and a pre-selected point is chosen within the imaging position domain as the imaging position, the imaging position is determined and remains unchanged.

[0070] Example 4

[0071] This embodiment further defines and explains the imaging position based on Embodiment 2. This embodiment also explains the case where the imaging position is variable.

[0072] In Example 2, the imaging position cannot be changed once it is determined, and it cannot be adjusted according to the actual position of the passenger, which is not flexible and convenient enough. This example proposes an improved solution to address this problem.

[0073] It should be noted that the variable imaging position here includes: 1) the projection position of the imaging position on the car floor is variable; 2) the height of the imaging position relative to the car floor is variable; 3) both the projection position of the imaging position on the car floor and the height of the imaging position relative to the car floor are variable.

[0074] To achieve a variable imaging position, a fixing device is used to fix the imaging device at its installation position inside the car. This fixing device includes a fixed part, a movable part, and an adjustable part. The fixed part is fixedly installed at the installation position, the movable part is fixedly connected to the imaging device, and the fixed part and the movable part are respectively connected to the adjustable part. The adjustable part can adjust the relative angle between the fixed part and the movable part in at least one direction. Preferably, the adjustment direction of the adjustable part is the car depth direction. This allows the distance between the imaging position and the plane of the car door to be adjustable, and the imaging position and its height relative to the car floor are also adjustable. However, the imaging position is not adjustable in the opening and closing direction of the car door, or the adjustment range is very limited, unless the adjustment direction of the adjustable part is no longer limited to the car depth direction. For example, when the imaging device is fixed to the car ceiling, the adjustment direction can be any direction where the angle between the imaging device and the downward vertical line from the car ceiling does not exceed θ (not exceeding 90°).

[0075] The elevator information input system also includes: a third detection device, used to detect passengers entering the car and output passenger information;

[0076] The control device determines the desired imaging position based on the passenger information, and further controls the adjustable part based on the installation position of the imaging device and the desired imaging position, so that the imaging device can provide an input interface to the passenger at the desired imaging position and receive the first information input by the passenger through the operation input interface.

[0077] The passenger information includes the real-time location of the passenger and height-related information (height, head height, shoulder height, etc.) used to determine the appropriate height for the passenger to perform input operations. The control device determines the vertical position (i.e., the height relative to the car floor) of the desired imaging position based on the height-related information of the passenger, and determines the horizontal position of the desired imaging position based on the real-time location of the passenger. Finally, the desired imaging position is obtained by combining the vertical and horizontal positions.

[0078] Obviously, as a passenger enters the car and reaches its final stop, its position within the car is constantly changing. The control device determines an imaging position based on this constantly changing passenger position, facilitating the passenger's operation of the input interface provided by the imaging device. This imaging position changes as the passenger moves until the passenger completes information input using the input interface.

[0079] Example 5

[0080] This embodiment is a further explanation based on embodiment 4.

[0081] Based on Embodiment 4, the elevator information input system of this embodiment further includes: a fourth detection device for detecting the current occupancy status inside the car;

[0082] The control device determines the vertical position of the desired imaging location based on the height-related information of the entering passenger, and determines the horizontal position of the desired imaging location based on the real-time position of the entering passenger and the current occupancy status inside the car. Finally, the desired imaging location is obtained by combining the vertical and horizontal positions. This embodiment, based on embodiment 4, considers the occupancy status inside the car, avoiding the awkward situation where the input interface is located on the occupying passenger when the imaging location is occupied.

[0083] It should be noted that in engineering practice, the fourth detection device here, and the second detection device, which is used to determine whether the point in the imaging position domain, or the perpendicular line segment between the point in the imaging position domain and the car floor, or the projection point of the point in the imaging position domain on the car floor and the moving path of the car door, is occupied, can be the same device. The reason for distinguishing between the second and fourth detection devices is simply for the purpose of differentiating the occupancy status inside the car.

[0084] Example 6

[0085] The elevator information input system of this embodiment, based on embodiment 1, further includes a fifth detection device and a prompting device. The fifth detection device is used to detect the current occupancy status inside the car.

[0086] The control device determines a point from the imaging position domain as the imaging position based on the current occupancy status inside the car, and further determines an optimal stopping position based on the determined imaging device.

[0087] The notification device provides incoming passengers with information including the optimal stopping location.

[0088] The prompting device is an imaging device that provides prompting information to passengers by displaying the prompting information to them on an interface. The function of the prompting device can be implemented by the imaging device, thereby reducing system complexity and cost. That is, in specific implementations, the imaging device can be used instead of configuring a separate prompting device.

[0089] The control device continuously determines the desired imaging position based on the real-time location information of the entering passenger, and controls the imaging device to provide an input interface to the entering passenger at the desired imaging position and receive the first information input by the passenger through the operation input interface, until the imaging device receives the first information input by the entering passenger through the operation input interface.

[0090] The present invention has been described in detail above through specific embodiments and examples, but these are not intended to limit the invention. Many modifications and improvements can be made by those skilled in the art without departing from the principles of the invention, and these should also be considered within the scope of protection of the present invention.
