All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
Referring to fig. 1, fig. 1 is a flow chart of a control method of an intelligent interactive terminal provided by the application, wherein the intelligent interactive terminal is installed at the back of a seat in a train, and the method comprises:
s11: acquiring the running direction of a train, and calling the corresponding relation between a preset seat number corresponding to the running direction and an IP address (Internet Protocol Address ) of the intelligent interaction terminal;
specifically, when considering that the running directions of trains are different, the orientations of seats are different, and thus the seat numbers of the intelligent interactive terminals disposed behind the seat backs may be different. Therefore, the running direction of the train is required to be acquired, and then the corresponding relation between the preset seat number corresponding to the running direction and the IP address of the intelligent terminal is called according to the running direction of the train. And when the method is equivalent to the method, the direction of the seats in the train is determined according to the running direction of the train, and then the seat numbers corresponding to the IP addresses of the intelligent interaction terminals are set for the intelligent interaction terminals.
S12: displaying the seat number corresponding to the IP address according to the IP address and the corresponding relation;
specifically, each intelligent interaction terminal has an IP address corresponding to itself, and the IP address represents the intelligent interaction terminal. After the corresponding relation between the called preset seat number and the IP address of the intelligent interaction terminal is determined, each intelligent interaction terminal displays the seat number corresponding to the IP address according to the IP address of the intelligent interaction terminal, so that a user can conveniently find the intelligent interaction terminal corresponding to the seat number of the user, the user can conveniently use the intelligent interaction terminal, and the user can be prevented from selecting the intelligent interaction terminal which does not correspond to the user to use the intelligent interaction terminal.
Referring specifically to fig. 2, fig. 2 is a schematic diagram of a train running direction and a seat orientation according to the present application. Specifically, the running directions of the trains are only two, so that the corresponding relation between the preset seat numbers and the IP addresses of the intelligent interaction terminals is also only two. In fig. 2, assuming that the running direction of the train corresponding to the upper half is forward running and the running direction of the train corresponding to the lower half is reverse running, the passenger with seat number 2A uses the intelligent interactive terminal behind the seat with seat number 1A during forward running; in the reverse driving, the passenger with seat number 2A uses the intelligent interactive terminal behind the seat with seat number 3A. That is, in the forward running, the seat number displayed by the intelligent interactive terminal behind the seat with the seat number of 1A is 2A, the seat number displayed by the intelligent interactive terminal behind the seat with the seat number of 2A is 3A, and so on. And when the vehicle runs in the reverse direction, the intelligent interaction terminal behind the seat with the seat number of 2A displays the seat number of 1A, the intelligent interaction terminal behind the seat with the seat number of 3A displays the seat number of 2A, and so on.

Further, when the running directions of the trains are different, the directions of the seats are different, and when the intelligent interaction terminals corresponding to the seat numbers are different, besides the seat numbers displayed by the intelligent interaction terminals are automatically changed, the earphone sound sources corresponding to each intelligent interaction terminal are also automatically switched. Specifically, when the train is determined to run in the forward direction, namely when the train is determined to run in the left direction, namely when the train is determined to run in the reverse direction, namely when the train is determined to run in the 8-train main control, the entertainment audio is set to run in the right direction, wherein the entertainment audio of the seat is output by the seat entertainment terminal in front of the running direction; the broadcast audio is given by a carriage controller, and the control box below the seat correspondingly outputs the broadcast audio.
In addition, the intelligent interactive terminal of the present application can display the seat number and the audio/video information through the display screen 31, and the overall structure thereof can refer to fig. 3 and fig. 4, fig. 3 is a schematic structural diagram of an intelligent interactive terminal provided by the present application, and fig. 4 is a schematic rotational and limiting structural diagram of an intelligent interactive terminal provided by the present application. Specifically, the intelligent interaction terminal is mounted on the back of the seat through a mounting frame 32, the specific implementation manner of the mounting frame 32 may be a rotating mechanism, and the display screen 31 may be an LCD (Liquid Crystal Display ) or OLCD (Organic Light-Emitting Diode) display screen. The rotation mechanism is provided with a limit column 41 for limiting the opening angle of the display screen 31 to be 0-60 degrees, and the overlarge opening angle is prevented from being resisted with the back of the seat.
