Description

Elevator media playing method

Technical Field

The invention relates to the field of elevators, in particular to an elevator media playing method.

Background

In recent years, liquid crystal displays have been widely used in elevators because of their advantages such as rich display contents and excellent display effects. With the help of the liquid crystal display, the elevator display is gradually changed from simple floor display and direction display to richer and more diverse video content display, and the content gradually develops to interestingness, knowledge and continuity, such as public welfare publicity films for safely taking a ladder, publicity of specific floor states and the like. The obvious characteristics of the display content are that the total playing time is relatively long, the display content is composed of a plurality of short chapters, and the different chapters have relative independence on the content but also have a certain sequence. Although the chapters of the display content can be independently played, the chapters can be continuously played in the chapter sequence to obtain better playing effect.

At present, the playing of the elevator display content is mostly ensured that the elevator can completely play the content during the running period between the departure floor and the destination floor, and the situation that the passenger is uncomfortable because the content cannot be completely played before reaching the destination floor is avoided. Such techniques are directed to the complete play problem of a single play content, and have not considered the association relationship between a plurality of play contents.

For the display content formed by a plurality of associated chapters with a front-to-back sequence, the Chinese patent with the authority bulletin number of CN110382388B proposes a content playing scheme based on the number of passengers, wherein the playing content is divided into a plurality of chapters, each chapter is provided with different sub-playing contents according to the number of passengers, and when in playing, the chapters containing the corresponding sub-playing contents are selected according to the number of passengers in a lift car according to the sequence for playing, and as the chapters are played according to the sequence, the continuity of the playing contents is ensured; and on the basis, passengers are further grouped according to video identification or passenger identity information, and chapter selection is performed according to the number of passengers in the group. Obviously, the scheme ensures the sequence of playing the content among different chapters and the corresponding relation between the content and the number of passengers by playing the chapter sub-playing content corresponding to the number of passengers according to the chapter sequence after each stop of the elevator car, but cannot ensure that the corresponding chapter can be completely played in the driving period of the adjacent stop floor.

In view of the above, how to ensure the integrity of chapter playback in the elevator car according to the sequence of the different chapters of the playback content becomes a technical problem to be solved.

11. The method according to claim 10, wherein the playing mode includes at least a playing start time, and the step S5 determines the playing start time of the next selected media-associated floor after the step S4 determines the next selected media-associated floor.

12. The method according to claim 4, characterized in that said step S4 determines all selected medium-associated floors in the current direction of travel after each start of the elevator car by said selected medium-associated floors or at the beginning of the first current direction of travel of the elevator.

13. The method according to claim 12, wherein the playing mode includes at least a playing start time, and the step S5 determines the playing start time of all the selected media-related floors after the step S4 determines all the selected media-related floors.

14. The elevator media playing method according to claim 11 or 13, characterized in that the playing start time refers to a time when the total playing duration of the media playing contents is shorter than the car moving time when the elevator car moves from the current position or the previous selected media-associated floor to the selected media-associated floor, and is obtained by advancing the total playing duration of the media playing contents from the estimated arrival time of the elevator car to the selected media-associated floor.

15. The elevator media playing method according to claim 14, wherein the playing start time is such that a car moving time taken for the elevator car to move from the playing start time to reach the selected media-related floor does not exceed a longest playing duration of a media theme corresponding to the selected media-related floor, and the longest playing duration of the media theme is a sum of playing durations of media files having longest playing durations in respective media chapters included in the media theme.

16. The method of claim 1, wherein when there is a floor to be parked between the current position of the elevator car and a selected floor associated with the medium that is closest to the front of the elevator operation, the step S5 further comprises the sub-steps of:

17. The method of claim 16, wherein the step S5-3 is performed as follows:

And S5-34, deleting the selected sub-stroke, and returning to the step S5-31.

18. The method of claim 1, wherein when there is a floor to be parked between the current position of the elevator car and a selected floor associated with the medium that is closest to the front of the elevator operation, the step S5 further comprises the sub-steps of:

19. The elevator media playing method according to claim 18, wherein when the car moving time of the selected sub-trip is longer than the shortest playing time length of the media theme of the selected media-associated floor, the step S5-6 selects the media playing content composed of the media files having the longest playing time length from among the media playing contents having all the playing time lengths not exceeding the car moving time of the selected sub-trip, and allocates it to the selected media-associated floor, the playing start time being a time not later than a time obtained by advancing the playing time length of the media playing content from the estimated arrival time when the elevator car arrives at the selected media-associated floor.

20. The elevator media playing method according to any one of claims 16 to 19, characterized in that the floor to be parked is generated by an external boarding call signal and/or a destination floor registration signal from an elevator user.
