[0066] The technical solution of the present invention is further described in detail below through the accompanying drawings and embodiments. BRIEF DESCRIPTION OF THE DRAWINGS

[0067] The accompanying drawings are used to provide a further understanding of the present invention and constitute a part of the specification. Together with the embodiments of the present invention, they are used to explain the present invention and do not constitute a limitation of the present invention. In the accompanying drawings:

[0069] Figure 2 Schematic diagram of an elevator intelligent interaction system in an embodiment of the present invention. DETAILED DESCRIPTION

[0070] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0071] The embodiment of the present invention provides an elevator intelligent interaction method, such as Figure 1 As shown, including:

[0072] S1. Based on the current floor of the elevator, the floor where each passenger in the elevator is going down, and the running speed of the elevator, predict the remaining time for each passenger to go down the elevator;

[0073] S2. Determine whether to enter the interaction time based on the remaining time for each passenger to get off the elevator;

[0074] S3, when the answer is yes, based on the remaining time for each passenger to get off the elevator, the personnel portrait of each passenger and the interactive material library, a decision is made to generate interactive materials;

[0075] S4. Based on the interactive material, control the elevator to interact with each passenger.

[0076] In the above technical solution:

[0077] The current floor of the elevator refers to the floor the elevator is currently on; the descending floor of each passenger in the elevator refers to the floor to which each passenger is heading; the operating speed of the elevator refers to the average speed of the elevator when it is descending and ascending.

[0078] Knowing the current floor of the elevator, the floor where each passenger is getting off the elevator, and the running speed of the elevator, the remaining time for each passenger to get off the elevator can be predicted. The remaining time for getting off the elevator refers to the time it takes the user to get off the elevator from the current distance. It is calculated by dividing the elevator running distance between the current floor and the floor where the passenger is getting off the elevator by the running speed of the elevator.

[0079] The passenger's profile includes: gender, age, number of times he / she has taken the elevator in the past, company type, type of items worn on the back, etc. The interactive material library contains a large number of interactive materials, which are used to control the elevator and interact with each passenger, such as talking virtual characters.

[0080] Based on the remaining time for each passenger to get off the elevator, determine whether to enter the interaction time. If yes, decide to generate interaction materials based on the remaining time for each passenger to get off the elevator, the personal portrait of each passenger and the interaction material library. Based on the interaction materials, control the elevator to interact with each passenger.

[0081] The present application controls the elevator to interact with each passenger, effectively distracting the passengers' attention while waiting for the elevator, preventing the passengers from feeling bored, tired or even impatient, thereby improving the experience of the passengers using the elevator and improving the comfort of the passengers when riding the elevator.

[0082] In one embodiment, determining whether to enter the interaction opportunity based on the remaining time for each passenger to get off the elevator includes:

[0083] When the remaining time for each passenger to get off the elevator meets the timing entry condition, the interaction timing is determined; otherwise, it is determined not to enter the interaction timing;

[0084] Among them, the timing entry conditions include:

[0085] The remaining time for passengers who exceed the number threshold to get off the elevator is greater than or equal to the first time threshold; the number threshold may be 3; the first time threshold may be 25 seconds; when this timing entry condition is met, it means that many passengers will wait in the elevator for a long time, and the elevator needs to interact with the passengers, so the timing for entering the interaction is determined;

[0086] and / or,

[0087] The maximum value of the remaining time for each passenger to get off the elevator is greater than or equal to the second time threshold; the second time threshold may be 40 seconds; when this timing entry condition is met, it means that a passenger will wait in the elevator for a particularly long time, and the elevator needs to interact with the passenger, so the timing for entering the interaction is determined;

[0088] and / or,

[0089] The number of passengers in at least one target passenger set is greater than or equal to the number threshold; the absolute value of the difference between the remaining time to get off the elevator of two passengers in the same target passenger set is less than or equal to the first difference threshold. The number threshold can be 2; the first difference threshold can be 5 seconds; when this timing entry condition is met, it means that some members will get off the elevator at a similar time, and the elevator can interact with these passengers at the same time, then the timing of entering the interaction is determined;

[0090] The embodiment of the present invention introduces a timing entry condition. Based on the timing entry condition, whether to enter the interaction opportunity is determined according to the remaining time for each passenger to get off the elevator, thereby improving the efficiency, accuracy and comprehensiveness of the interaction opportunity entry determination.

[0091] In one embodiment, the decision to generate interactive materials based on the remaining time for each passenger to get off the elevator, the personnel portrait of each passenger and the interactive material library includes:

[0092] Based on the current time and the remaining time for each passenger to get off the elevator, determine the time for each passenger to get off the elevator; the time with the remaining time for getting off the elevator after the current time is the time for getting off the elevator;

[0093] Based on the time when each passenger gets off the ladder, the personnel portrait of each passenger is set on the time axis; the setting time of the personnel portrait of the same passenger on the time axis corresponds to the time when the passenger gets off the ladder; when setting the personnel portrait on the time axis, first find the time axis moment corresponding to the time when the passenger gets off the ladder, use the time axis moment as the setting time, and set the personnel portrait at the setting time;

[0094] Based on the portrait cluster division condition, the personnel portraits of each passenger set on the time axis are divided into multiple portrait clusters; constrained by the portrait cluster division condition, the personnel portraits on the time axis are divided into multiple portrait clusters; the personnel portraits of the same portrait cluster are suitable to be used as material screening basis at the same time;

[0095] Traverse each image cluster in turn;

[0096] When traversing to the i-th portrait cluster from left to right on the time axis, a material screening condition is generated; i=1, 2, 3, ..., N; N is the total number of portrait clusters; the order from left to right on the time axis is also the chronological order; each time a portrait cluster is traversed, a material screening condition is generated specifically; the material screening condition is a condition for screening out materials suitable for interacting with passengers with the portraits of each person in the i-th portrait cluster;

[0097] Based on the material screening conditions, sub-materials are screened out from the interactive material library; the sub-materials meet the material screening conditions;

[0098] Based on the interval demarcation rules, the target time interval is demarcated on the time axis;

[0099] Set the sub-material within the target time interval; when setting, expand the sub-material within the target time interval. For example, if the sub-material is a playback screen, when setting, the playback screen is divided into frames in the form of a screen frame sequence and set at different time nodes within the target time interval;

[0100] After traversing each image cluster, the interactive material is generated based on the sub-materials set in different target time intervals on the time axis. After traversing each image cluster, there will be multiple target time intervals on the time axis, and different sub-materials will exist in different target time intervals. When generating interactive materials, the sub-materials set in different target time intervals on the time axis are merged to obtain interactive materials.

[0101] The embodiment of the present invention introduces a time axis when making decisions on generating interactive materials based on the remaining time for each passenger to get off the elevator, the personal portrait of each passenger and the interactive material library. The personal portrait is set on the time axis and divided into multiple portrait clusters. Material screening conditions are generated by traversing the portrait clusters in sequence, sub-materials are screened out from the interactive material library, and the sub-materials are set within a designated target time interval. Interactive materials are generated based on the sub-materials set within different target time intervals on the time axis, which greatly improves the suitability, efficiency and comprehensiveness of interactive material generation.

[0102] In one embodiment, the image cluster division conditions include:

[0103] The time difference between the setting moments of two adjacent person portraits in the same portrait cluster is less than or equal to the second difference threshold.

[0104] The second difference threshold can be 10 seconds; by setting this portrait cluster division condition, the passengers corresponding to the portraits in the same portrait cluster can be the passengers who will successively get off the elevator in a similar time in the future, so the portraits in the same portrait cluster are suitable as the basis for material screening at the same time.

[0105] In one embodiment, the material screening conditions include:

[0106] The sub-material meets at least one material applicable condition of all the personnel portraits in the traversed i-th portrait cluster; different personnel portraits are preset with material applicable conditions, and the material applicable conditions are the conditions of the material represented by the personnel portrait that is suitable for interacting with the occupant, for example, if the personnel portrait is that the occupant is 8 years old, then the material applicable condition is that the material is a children's animation; setting this material screening condition can make the sub-material suitable for interacting with the occupants corresponding to all the personnel portraits in the i-th portrait cluster;

[0107] and,

[0108] When i>1, the association weight between the sub-material and other sub-materials selected from the interactive material library when traversing to the ijth portrait cluster from left to right on the timeline is greater than or equal to the weight threshold; the weight threshold is the corresponding value of the cluster interval between the ijth portrait cluster and the i-th portrait cluster in the threshold library; ij>0. There are preset association weights between different sub-materials, and the association weight represents the degree of association between the sub-materials. The degree of association refers to the degree of association between the contents of different sub-materials. For example, if both sub-materials are children's animations, the association is relatively large, and the association weight can be 8; the cluster interval refers to the time difference between the setting time of the last person portrait in the ijth portrait cluster and the setting time of the first person portrait in the ith portrait cluster; there are weight thresholds corresponding to different cluster intervals in the threshold library. The larger the cluster interval, the later the occupant corresponding to the person portrait in the ith portrait cluster gets off the ladder than the occupant corresponding to the person portrait in the ijth portrait cluster, and the lower the weight threshold can be set, reducing the requirement for the association weight between the sub-material and other sub-materials, and therefore, the corresponding weight threshold is lower; setting this material screening condition can ensure that the sub-materials screened out each time the portrait cluster is traversed can have an adaptively determined association, which greatly improves the suitability of sub-material screening.

[0109] In one embodiment, the interval demarcation rules include:

[0110] When i=1, the time axis moment corresponding to the current moment in time is taken as the starting moment of the target time interval; when i=1, it means that the first portrait cluster has been traversed, and the time axis moment corresponding to the current moment in time is taken as the starting moment of the target time interval;

[0111] When i>1, the time when the last person portrait in the i-1th portrait cluster from left to right on the time axis is set is used as the starting time of the target time interval; in this way, the sub-material can be used to perform elevator interactive control as soon as possible after the last passenger corresponding to the person portrait in the previous portrait cluster gets off the elevator;

[0112] The time when the last person portrait in the traversed i-th portrait cluster on the time axis is set is taken as the end time of the target time interval. In this way, the elevator interactive control can be performed using the sub-material as much as possible until the last passenger in the portrait cluster corresponding to the person portrait gets off the elevator, which greatly improves the suitability of the target time interval delineation.

[0113] The embodiment of the present invention provides an elevator intelligent interaction system, such as Figure 2 As shown, including:

[0114] Prediction module 1, used to predict the remaining time for each passenger to get off the elevator based on the current floor of the elevator, the floor where each passenger in the elevator is getting off, and the running speed of the elevator;

[0115] Determination module 2, used to determine whether to enter the interaction opportunity based on the remaining time for each passenger to get off the elevator;

[0118] The determination module determines whether to enter the interaction opportunity based on the remaining time for each passenger to get off the elevator, including:
