Description

Technical Field

[0001] This invention relates to the field of elevators, and more specifically to an information registration method for elevators to perform information registration in a non-contact manner. Background Technology

[0002] To prevent the spread of germs, many elevators are equipped with contactless registration systems for passengers to register at their destination floor, such as CN202180069277.8 and CN202211535595.1. While contactless registration offers many benefits to passengers, it also has a significant technical drawback: it can lead to incorrect registration. Several solutions have been developed in the industry to address this issue, such as:

[0003] Reference 1 (CN202180095319.5) proposes that in an elevator equipped with non-contact sensors for detecting input from passengers, when the input information of the non-contact sensor is consistent with the input detection conditions, the input information of the non-contact sensor is registered when the input information becomes inconsistent with the input detection conditions; furthermore, when multiple input information from non-contact sensors are detected, only the single input detection condition is registered when the input information of the non-contact sensor is a single input information.

[0004] The contactless elevator button system proposed in Reference 2 (CN202010542077.7) includes: at least two elevator buttons using a contactless registration method; a construction unit that constructs the movement trajectory of the operation execution body based on the operation information of the operation execution body and / or the operation information of the elevator button; a judgment unit that determines whether there is an elevator button with a mistakenly registered operation based on the movement trajectory or the movement trajectory and the operation information of the elevator button; and an identification unit that, when there is an elevator button with a mistakenly registered operation, identifies all elevator buttons with the registered operation based on the movement trajectory or based on at least one of the operation information of the operation execution body and the operation information of the elevator button combined with the movement trajectory.

[0005] However, these solutions rely on complex logic processing to identify and eliminate incorrect registrations. There is a certain error rate in identifying incorrect registrations, and passengers do not know the registration result determined by the registration system before the system determines the actual registration result. Therefore, passengers still need to make corrections after discovering the registration error.

[0006] Therefore, how to provide passengers with a simple, accurate, and effective contactless registration process has become a pressing technical issue. Summary of the Invention

[0007] The technical problem this invention aims to solve is how to provide passengers with a simple, accurate, and effective contactless registration process.

[0008] To address the aforementioned technical problems, this invention discloses a contactless information registration method for elevators, comprising:

[0009] Step 1: Detect objects approaching the sensor and output a detection signal;

[0010] Step 2: Determine the location of the approaching object that has entered the detection range based on the detection signal;

[0011] Step 3: Determine the location of the sign based on the location of the nearby object;

[0012] Step 4: Control the display screen to display the logo at the specified location;

[0013] Step 5: When the detection signal meets the first preset condition, or the location of the approaching object meets the second preset condition, or the location of the marker meets the third preset condition, determine the current location of the marker;

[0014] Step 6: Determine the registration signal corresponding to the current identification position and send it to the elevator control system.

[0015] Preferably, the step 1 continuously or periodically detects objects entering the detection range of the sensor and outputs a detection signal; the step 2 determines and updates the position of the object based on the changed detection signal when a change in the detection signal is detected.

[0016] Preferably, when multiple sensors simultaneously detect an approaching object entering the detection range, step 2 determines the position of the approaching object in any of the following ways:

[0017] Method 1: The position of the display screen corresponding to the nearest object to the sensor is taken as the position of the object.

[0018] Method 2: The position of the display screen corresponding to the nearest object farthest from the center point is taken as the position of the nearest object. The center point is the position of the display screen corresponding to the average coordinate of the display screen positions of each nearest object detected by the sensor and entering the detection range.

[0019] Method 3: The first detected approaching object is taken as the first approaching object, the movement trajectory of the first approaching object is recorded, and the position of the display screen corresponding to the foremost point of the movement trajectory is taken as the position of the approaching object;

[0020] Method 4: Record the first detected approaching object and its movement trajectory. For the subsequently detected second approaching object, determine the position of the approaching object based on the positional relationship between the movement estimates of the second approaching object and the first approaching object.

[0021] Preferably, in method 4,

[0022] If the second approaching object is located within the movement trajectory of the tracking point, it is considered a valid approaching object detected simultaneously. For valid approaching objects, the position of the approaching object is further determined using any of methods 1 to 3; otherwise...

[0023] Determine the relationship between the minimum distance between the second approach object and the currently valid approach object and the first threshold. If the minimum distance is less than the first threshold, the second approach object is treated as an invalid approach object and ignored. Otherwise, the second approach object is used as the start of a new registration operation.

[0024] Preferably, in step 3, the position of the approaching object is moved by a movement vector, and the endpoint of the movement vector is taken as the marker position. The movement vector starts from the position of the approaching object before the movement, and its movement direction is a selected direction and its movement distance is a selected length.

[0025] Preferably, step 3 involves inferring the registration operator's line of sight formed by the line connecting the registration operator's eye and the location of the approaching object, and determining the selected direction and selected length of the movement vector based on the angle of the registration line of sight relative to the display screen and the length of the registration line of sight.

[0026] Preferably, step 3 determines the selected length based on one or more of the following: the size of the operation object identifier displayed on the screen, the distance between adjacent operation object identifiers, the minimum distance between the boundary lines of adjacent operation object identifiers, and the moving speed of the approaching object.

[0027] Preferably, step 3 determines the selected direction based on one or more of the following: the movement direction of the foremost point of the approaching object, the relative position of the approaching object in the display screen, the position of the display screen inside the car, and the height of the approaching object relative to the foot of the registered operator.

[0028] Preferably, the first preset condition includes:

[0029] Condition A1: No new sensors detect approaching objects.

[0030] The duration for which conditions A2 and A1 are met exceeds the second threshold.

[0031] Preferably, the detection signal is the distance between the approaching object and the sensor, and the smaller the distance, the higher the intensity of the detection signal; the first preset condition further includes:

[0032] Condition A3: The intensity change of the detected signal does not exceed a third threshold; or it further includes:

[0033] The duration for which conditions A4 and A3 are met exceeds the fourth threshold.

[0034] Preferably, the detection signal is the distance between the approaching object and the sensor, and the smaller the distance, the higher the intensity of the detection signal; the first preset condition is that the intensity change of the detection signal conforms to a preset change law.

[0035] Preferably, the second preset condition includes at least one of the following conditions:

[0036] Condition B1: The duration for which the position of the approaching object remains substantially unchanged exceeds the fifth threshold.

[0037] Condition B2: Within a given time period, the maximum distance between the locations of the approaching objects at any two times does not exceed the sixth threshold.

[0038] Preferably, the third preset condition includes at least one of the following conditions:

[0039] Condition C1: The duration for which the identifier position remains substantially unchanged exceeds the seventh threshold;

[0040] Condition C2: Within a given time period, the maximum distance between the identified locations at any two times does not exceed the eighth threshold.

[0041] Preferably, step 4 controls the display screen to display the identifier at the identifier position, such that the display screen displays the identifier between a first moment and a second moment, where the second moment refers to the moment when the sensor first detects an approaching object entering the detection range, and the second moment refers to the moment when the registration signal for this registration operation is determined.

[0042] Preferably, when a new registration operation is detected, step 4 controls the display screen to display an identifier corresponding to different registration operations, and the display screen displays the identifier between the first time and the second time corresponding to the operation registration; for the first registration operation, the first time refers to the time when the sensor first detects an approaching object entering the detection range, and the second time refers to the time when the registration signal of this registration operation is determined; for non-first registration operations, the first time refers to the time when the sensor first recognizes the occurrence of a new registration operation, and the second time refers to the time when the registration signal of the new registration operation is determined.

[0043] Preferably, step 6 determines whether the current identifier position is within the boundary line of a certain operation identifier displayed on the screen, and when the determination result is yes, the registration signal corresponding to the operation identifier is used as the registration signal corresponding to the current identifier position; otherwise, the operator is reminded to modify their registration operation in a visually or audibly acceptable manner.

[0044] Preferably, step 6 divides the display area according to the various operation icons displayed on the screen to obtain several display sub-areas;

[0045] The corresponding operation identifier is determined based on the display sub-area where the identifier is located, and the registration signal of the operation identifier within the corresponding operation identifier is used as the registration signal corresponding to the current identifier position.

[0046] Preferably, the display area is divided into several display sub-areas based on the various operation indicators displayed on the display screen;

[0047] When the marked position is within the boundary line, step 6 determines the adjacent display sub-region of the boundary line at the marked position, and uses the display sub-region pointed to by the movement vector as the registration signal corresponding to the current marked position.

[0048] Beneficial technical effects

[0049] This invention provides convenience for passengers' contactless registration by controlling the display screen to show a marker at a location determined based on a proximity detection signal when preset conditions are met. Therefore, it helps to reduce the phenomenon of erroneous registration when the contactless registration system accepts passengers' contactless registration operations. Detailed Implementation

[0050] Example 1

[0051] The contactless information registration method for elevators provided in this embodiment includes the following steps:

[0052] Step 1: Detect objects approaching the sensor and output a detection signal;

[0053] Step 2: Determine the location of the approaching object that has entered the detection range based on the detection signal;

[0054] Step 3: Determine the location of the sign based on the location of the nearby object;

[0055] Step 4: Control the display screen to display the logo at the specified location;

[0056] Step 5: When the detection signal meets the first preset condition, or the location of the approaching object meets the second preset condition, or the location of the marker meets the third preset condition, determine the current location of the marker;

[0057] Step 6: Determine the registration signal corresponding to the current identification position and send it to the elevator control system.

[0058] Example 2

[0059] This embodiment is a further explanation based on Embodiment 1.

[0060] Step 1: Continuously or periodically detects objects approaching the sensor's detection range and outputs a detection signal; Step 2: When a change in the detection signal is detected, the position of the approaching object is determined and updated based on the changed detection signal.

[0061] When only one sensor detects an approaching object entering the detection range, step 2 takes the display screen position corresponding to the detected approaching object as the position of the approaching object; when multiple sensors simultaneously detect an approaching object entering the detection range (here, "simultaneously" means that before the first sensor detects the first approaching object entering the detection range and the system completes the signal registration operation for the approaching object, other second sensors, different from the first sensor, detect a second approaching object different from the first approaching object, so the first sensor and the second sensor are referred to as "multiple sensors simultaneously detecting an approaching object entering the detection range"), step 2 determines the position of the approaching object in any of the following ways:

[0062] Method 1: The position of the display screen corresponding to the nearest object to the sensor is taken as the position of the object.

[0063] Method 2: The position of the display screen corresponding to the nearest object farthest from the center point is taken as the position of the nearest object. The center point is the position of the display screen corresponding to the average coordinate of the display screen positions of each nearest object detected by the sensor and entering the detection range.

[0064] Method 3: The first detected approaching object is taken as the first approaching object, the movement trajectory of the first approaching object is recorded, and the position of the display screen corresponding to the foremost point of the movement trajectory is taken as the position of the approaching object;

[0065] Method 4: Record the first detected approaching object and its movement trajectory. For the subsequently detected second approaching object, determine the position of the approaching object based on the positional relationship between the movement estimates of the second approaching object and the first approaching object.

[0066] In Method 4, if the second approaching object is located within the movement trajectory of the tracking point, Step 2 treats it as a valid approaching object that is detected simultaneously. For the valid approaching object, any of Methods 1 to 3 is used to determine the position of the approaching object. Otherwise, Step 2 determines the relationship between the minimum distance between the second approaching object and the currently existing valid approaching object and the first threshold. If the minimum distance is less than the first threshold, the second approaching object is treated as an invalid approaching object and ignored. Otherwise, the second approaching object is used as the start of a new registration operation.

[0067] Example 3

[0068] This embodiment further details step 3 based on the aforementioned embodiments.

[0069] Step 3: Move the position of the approaching object by a movement vector, and use the end point of the movement vector as the marker position. The movement vector starts from the position of the approaching object before the movement, and its movement direction is a selected direction and its movement distance is a selected length.

[0070] Step 3: Predict the registration line of the registration operator formed by the line connecting the registration operator's eye and the location of the approaching object. Determine the selected direction and selected length of the movement vector based on the angle of the registration line relative to the display screen and the length of the registration line, so that the mark displayed on the display screen can be seen by the registration operator.

[0071] Alternatively, step 3 determines the selected length based on one or more of the following: the size of the operation object icon displayed on the screen, the distance between adjacent operation object icons, the minimum distance between the boundary lines of adjacent operation object icons, and the moving speed of the approaching object; step 3 determines the selected direction based on one or more of the following: the estimated moving direction of the foremost end of the approaching object, the relative position of the approaching object on the screen, the position of the screen inside the car, and the height of the approaching object relative to the foot of the registered operator.

[0072] Example 3

[0073] This embodiment further details step 5 based on the foregoing embodiments. In step 5,

[0074] The first precondition includes:

[0075] Condition A1: No new sensors detect approaching objects.

[0076] The duration for which conditions A2 and A1 are met exceeds the second threshold.

[0077] When the detection signal is the distance between the approaching object and the sensor, and the smaller the distance, the higher the intensity of the detection signal, the first preset condition further includes:

[0078] Condition A3: The intensity change of the detected signal does not exceed a third threshold; or it further includes:

[0079] The duration for which conditions A4 and A3 are met exceeds the fourth threshold.

[0080] Alternatively, when the detection signal is the distance between the approaching object and the sensor, and the smaller the distance, the higher the intensity of the detection signal, the first preset condition can also be: the intensity change of the detection signal conforms to a preset change law.

[0081] The second preset condition includes at least one of the following conditions:

[0082] Condition B1: The duration for which the position of the approaching object remains substantially unchanged exceeds the fifth threshold.

[0083] Condition B2: Within a given time period, the maximum distance between the locations of the approaching objects at any two times does not exceed the sixth threshold.

[0084] The third precondition includes at least one of the following conditions:

[0085] Condition C1: The duration for which the identifier position remains substantially unchanged exceeds the seventh threshold;

[0086] Condition C2: Within a given time period, the maximum distance between the identified locations at any two times does not exceed the eighth threshold.

[0087] Example 4

[0088] This embodiment further details step 4 based on the aforementioned embodiments.

[0089] When there is only one registration operation or for the first registration operation in multiple registration operations, step 4 controls the display screen to display the identifier at the identifier position, so that the display screen displays the identifier between the first moment and the second moment, the second moment refers to the moment when the sensor first detects the approaching object entering the detection range, and the second moment refers to the moment when the registration signal of this registration operation is determined.

[0090] When a new registration operation is detected, step 4 controls the display screen to display the identifiers corresponding to different registration operations, and the display screen displays the identifiers between the first time and the second time corresponding to the operation registration. For the first registration operation (a registration operation that occurs after the end of an operation registration is still considered the first; a new registration operation that occurs before the end of an operation registration is considered a non-first operation), the first time refers to the time when the sensor first detects an approaching object entering the detection range, and the second time refers to the time when the registration signal of this registration operation is determined. For non-first registration operations, the first time refers to the time when the sensor first recognizes the occurrence of a new registration operation, and the second time refers to the time when the registration signal of the new registration operation is determined.

[0091] Example 5

[0092] This embodiment further details step 6 based on the aforementioned embodiments.

[0093] Step 6 determines whether the current identifier position is within the boundary line of an operation identifier displayed on the screen, and

[0094] If the judgment result is yes, the registration signal corresponding to the operation identifier will be used as the registration signal corresponding to the current identifier position; otherwise, the operator will be reminded to modify their registration operation in a visually or audibly acceptable manner.

[0095] Alternatively, in step 6, the display area is divided into several sub-regions based on the various operation identifiers displayed on the screen; the corresponding operation identifier is determined according to the sub-region where the identifier is located, and the registration signal of the operation identifier within the corresponding operation identifier is used as the registration signal corresponding to the current identifier position.

[0096] Alternatively, step 6 divides the display area into several display sub-areas based on the various operation icons displayed on the screen; when the icon position is within the boundary line, step 6 determines the adjacent display sub-area of ​​the boundary line at the icon position, and uses the display sub-area pointed to by the movement vector as the registration signal corresponding to the current icon position.

[0097] Preferably, the display screen shows the boundary lines of adjacent display sub-regions in a manner recognizable by a registered operator.

[0098] 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.
