Description

TECHNICAL FIELD

[0001] The present application relates to elevator technology, in particular to an elevator signal registration system with both contact operation and non-contact operation functions. BACKGROUND

[0002] In order to solve the problem of germ transmission caused by the contact operation of traditional contact type elevator buttons, various non-contact buttons have appeared in the market. For example, a non-contact elevator button based on capacitive non-contact technology is proposed in Chinese patent application No. 201610551225.5, but the technical solution in the patent application has the problem of misregistration. In view of the problem of misregistration of elevator buttons, Chinese patent application No. 200710051927.8 proposes a non-contact switch type elevator panel, which realizes non-contact operation by adding a partition plate on the outer panel of the button and setting a light-emitting tube and a light-sensitive plate on the partition plate. Chinese patent application No. 201810845136.0 uses an ultrasonic sensor arranged in the elevator button to generate and receive ultrasonic waves, and judges whether the gesture corresponds to a request for an upward call or a request for a downward call according to the sequence of the received ultrasonic echo signals.

[0003] The above prior art for solving the misregistration problem does not consider the scenario that the operation panel can accept both contact operation and non-contact operation, i.e., the operation panel can accept both contact operation and non-contact operation of the passenger. In this case, during the process that the passenger moves the hand due to the registration of the call signal, gradually approaches and contacts the button, and then leaves, the operation panel will first detect the non-contact operation, then detect the contact operation, and finally detect the non-contact operation again until the hand of the passenger leaves the detection range of the non-contact operation. Obviously, the non-contact operation and the contact operation at this time actually correspond to the same operation of the passenger, which is intended to register a contact operation signal, but actually registers both the signal corresponding to the non-contact operation and the signal corresponding to the contact operation, which is obviously unreasonable. In order to solve the problem, CN202180069277.8 proposes that: in the case of detecting contact operation, during at least one of a first period starting from a predetermined time before the time point of detecting the contact operation to the time point and a second period starting from the time point to a predetermined time after the time point, in the case of detecting non-contact operation, the non-contact operation is not accepted, or further, at least one of (1) the non-contact operation detection part corresponding to the contact operation detection part of the operation panel at the time point of detecting the contact operation, (2) the non-contact operation detection part arranged around the contact operation detection part at the time point of detecting the contact operation, and (3) all the non-contact operation detection parts detects non-contact operation during at least one of the first period and the second period. However, this scheme can overcome the shortcoming of the prior art that the contact operation signal and the non-contact operation signal are generated at the same time for the contact operation of the passenger, but when two different passengers register two different call signals at the same time by contact operation and non-contact operation respectively (or further, the operation points of the two passengers are very close), the passenger who implements the non-contact operation registration will be confused due to the non-acceptance of the non-contact operation registration.

[0004] Therefore, how to accurately register the signal for the passenger in the case of being able to accept both contact operation and non-contact operation has become a technical problem to be solved. SUMMARY

[0005] The technical problem to be solved by the present application is to provide a signal registration system for an elevator, which accurately registers the signal for the passenger in the case of being able to accept both contact operation and non-contact operation.

[0006] In order to solve the above technical problem, the present application discloses a signal registration system for an elevator, comprising:

[0007] The operation panel has a contact operation detection part for detecting contact operation and a non-contact operation detection part for detecting non-contact operation.

[0008] a judging module configured to judge whether there is a time-space connection between the contact operation and the non-contact operation according to the first detection result of the contact operation detection part and the second detection result of the non-contact operation detection part, the time-space connection referring to the contact operation and the non-contact operation belonging to the same operation of the passenger should have in time and / or space;

[0009] a receiving module configured to only receive the contact operation detected by the contact operation detection part, generate and register an operation signal corresponding to the contact operation, and ignore the non-contact operation when the judging module judges that there is a time-space connection between the contact operation and the non-contact operation.

[0010] Preferably, the judging module determines the contact operation time of the contact operation detected by the contact operation detection part and the non-contact operation duration of the non-contact operation detected by the non-contact operation detection part, and judges whether there is a time connection between the contact operation and the non-contact operation according to the contact operation time and the non-contact operation duration, the non-contact operation duration being the duration of the non-contact operation continuously detected by a single non-contact operation detection part or the combination of the durations of the non-contact operation continuously detected by multiple non-contact operation detection parts, and the combination being continuous time durations.

[0011] Preferably, the judging module determines the operation point of the contact operation detected by the contact operation detection part and the position information of the non-contact operation detected by the non-contact operation detection part, and judges whether there is a space connection between the contact operation and the non-contact operation according to the operation point of the contact operation and the position information of the non-contact operation.

[0012] Preferably, the judging module determines the contact operation time and the operation point of the contact operation, and the non-contact operation duration and the position information of the non-contact operation, and judges whether there is a time-space connection between the contact operation and the non-contact operation according to the contact operation time and the operation point of the contact operation, and the non-contact operation duration and the position information of the non-contact operation.

[0013] Preferably, the judging module judges that there is a time connection between the contact operation and the non-contact operation when any of the following conditions is met:

[0014] Condition 1: the contact operation time is within the non-contact operation duration;

[0015] Condition 2: the time interval between the contact operation time and the start time of the non-contact operation duration is less than a time threshold;

[0016] Condition 3: the time interval between the contact operation time and the end time of the non-contact operation duration is less than a time threshold.

[0017] Preferably, the judging module generates a movement trajectory of the non-contact operation using the position information of the non-contact operation detected by the non-contact operation detection unit; and determines that there is a spatial connection between the contact operation and the non-contact operation when the minimum distance between the operation point of the contact operation and each point constituting the movement trajectory is less than a distance threshold.

[0018] Preferably, the judging module generates a movement trajectory of the non-contact operation using the position information of the non-contact operation detected by the non-contact operation detection unit; and determines that there is a spatio-temporal connection between the contact operation and the non-contact operation if the operation point of the contact operation is located within the movement trajectory and divides the movement estimation into two sub-trajectories, and when the longer the time interval between the detected time corresponding to each point in the sub-trajectory and the contact operation time, the longer the trajectory length between each point in the sub-trajectory and the operation point of the contact operation.

[0019] Preferably, the position information is the coordinate position of the non-contact operation detection unit in the operation panel, and the judging module obtains the movement trajectory by using a curve fitting method or connecting the coordinate positions of the non-contact operation detection units in the operation panel in the order of the detection of the non-contact operation by each non-contact operation detection unit.

[0020] Preferably, the position information is the first distance between the non-contact operation detection unit and the operation execution body, the coordinate position of the non-contact operation detection unit in the operation panel, and the judging module obtains the three-dimensional spatial coordinates of the operation execution body in space using the first distance and the coordinate position, and obtains the movement trajectory using the three-dimensional spatial coordinates of the operation execution body in space.

[0021] Preferably, when the durations of two non-contact operations overlap, if the judging module determines that there is no spatio-temporal connection between a certain non-contact operation and all contact operations, the receiving module recognizes the non-contact operation as an independent non-contact operation, and generates and registers the operation signal corresponding to the contact operation for the independent non-contact operation.

[0022] Preferably, when there are multiple non-contact operations with overlapping durations, the judging module determines whether the matching degree between the movement trajectories of each non-contact operation exceeds a matching threshold, and takes the non-contact operation corresponding to the movement trajectory with the matching degree exceeding the matching threshold as a non-contact operation group; for a non-contact operation group, when at least one non-contact operation in the group has a spatio-temporal connection with a contact operation, the receiving module ignores all non-contact operations in the group while accepting the contact operation.

[0026] Embodiment 1

[0027] The signal registration system for an elevator according to the present embodiment includes:

[0028] an operation panel having a contact operation detection unit for detecting a contact operation and a non-contact operation detection unit for detecting a non-contact operation;

[0029] a judging module for judging whether there is a spatio-temporal connection between the contact operation and the non-contact operation according to a first detection result of the contact operation detection unit and a second detection result of the non-contact operation detection unit, the spatio-temporal connection being a connection in time and / or space that the contact operation and the non-contact operation belonging to the same operation of a passenger should have;

[0030] a receiving module for, when the judging module determines that there is a spatio-temporal connection between the contact operation and the non-contact operation, only accepting the contact operation detected by the contact operation detection unit, generating and registering an operation signal corresponding to the contact operation while ignoring the non-contact operation.

[0031] Embodiment 2

[0032] The present embodiment considers the coping method when there are multiple non-contact operations.

[0033] When the durations of two non-contact operations overlap, if the judging module determines that a certain non-contact operation does not have a spatio-temporal connection with all contact operations, the receiving module recognizes the non-contact operation as an independent non-contact operation and generates and registers an operation signal corresponding to the contact operation for the independent non-contact operation.

[0034] Embodiment 3

[0035] The embodiment is based on the foregoing embodiment, and the judgment module is described in detail.

[0036] The judgment module determines whether there is a space-time connection between the contact operation and the non-contact operation in the following ways:

[0037] In way 1, the judgment module determines the contact operation time of the contact operation detected by the contact operation detection unit and the non-contact operation duration of the non-contact operation detected by the non-contact operation detection unit, and determines whether there is a time connection between the contact operation and the non-contact operation according to the contact operation time and the non-contact operation duration. The non-contact operation duration is the duration of the non-contact operation continuously detected by a single non-contact operation detection unit or the combination of the durations of the non-contact operation continuously detected by multiple non-contact operation detection units, and the combination is a continuous time period.

[0038] In way 2, the judgment module determines the operation point of the contact operation detected by the contact operation detection unit and the position information of the non-contact operation detected by the non-contact operation detection unit, and determines whether there is a space connection between the contact operation and the non-contact operation according to the operation point of the contact operation and the position information of the non-contact operation.

[0039] In way 3, the judgment module determines the contact operation time and operation point of the contact operation, and the non-contact operation duration and position information of the non-contact operation, and determines whether there is a space-time connection between the contact operation and the non-contact operation according to the contact operation time and operation point of the contact operation, and the non-contact operation duration and position information of the non-contact operation.

[0040] In way 1, when any of the following conditions is met, the judgment module determines that there is a time connection between the contact operation and the non-contact operation:

[0041] Condition 1: The contact operation time is within the non-contact operation duration;

[0042] Condition 2: The time interval between the contact operation time and the start time of the non-contact operation duration is less than a time threshold;

[0043] Condition 3: The time interval between the contact operation time and the end time of the non-contact operation duration is less than a time threshold.

[0044] In the manner 2, the judging module generates the moving track of the non-contact operation by using the position information of the non-contact operation detected by the non-contact operation detecting part, and judges that there is a spatial connection between the contact operation and the non-contact operation when the minimum distance between the operation point of the contact operation and each point of the moving track is less than the distance threshold (i.e. the operation point is within the moving estimation).

[0045] In the manner 3, the judging module generates the moving track of the non-contact operation by using the position information of the non-contact operation detected by the non-contact operation detecting part, and judges that there is a spatio-temporal connection (i.e. the connection in time and space) between the contact operation and the non-contact operation when the operation point of the contact operation is within the moving track and divides the moving estimation into two sub-tracks (one of the sub-tracks has a length of zero when the operation point is at the end), and the longer the time interval between the detected time corresponding to each point of the sub-track and the contact operation time, the longer the track length between each point of the sub-track and the operation point of the contact operation.

[0046] The moving track generating manner in the manners 2 and 3 is not limited in the embodiment, and can be various manners such as image recognition. Here, two preferred manners are given.

[0047] Manner A, the position information is the coordinate position of the non-contact operation detecting part in the operation disc, and the judging module obtains the moving track by using the curve fitting manner or connecting the coordinate positions of the non-contact operation detecting part in the operation disc according to the sequence of detecting the non-contact operation.

[0048] Manner B, the position information is the first distance between the non-contact operation detecting part and the operation execution body, and the coordinate position of the non-contact operation detecting part in the operation disc, the judging module obtains the three-dimensional space coordinates of the operation execution body in the space by using the first distance and the coordinate position, and obtains the moving track by using the three-dimensional space coordinates of the operation execution body in the space.

[0049] Embodiment 4

[0050] The embodiment is further explained based on the above-mentioned embodiment 3.

[0051] In the case of using the mode 2 or the mode 3, when there are multiple non-contact operations with overlapping time durations, the judging module judges whether the matching degree between the moving tracks of each non-contact operation exceeds a matching threshold, and regards the non-contact operation with the moving track corresponding to the matching degree exceeding the matching threshold as a non-contact operation group; for a non-contact operation group, when at least one non-contact operation in the non-contact operation group has a spatiotemporal connection with a contact operation, the receiving module ignores all non-contact operations in the non-contact operation group while receiving the contact operation.
