[0024] Example: The business class 400 of the train refers to the related conventional technology, and has two rows of seats 100 on the left and right, with a gap between the two rows of seats 100, and the gap forms an aisle, and the direction of the aisle is parallel to the length direction of the business class 400. In the related art, the layout of the seats 100 in a part of the business class 400 is bilaterally symmetrical, and the layout of the seats 100 in another part is left-right staggered. The following is a specific description using the bilaterally symmetrical layout as an example, and the left-right staggered seat 100 layout can also apply the control steering system disclosed in this article, and the examples provided in this article are not intended to be limiting.

[0025] Each seat 100 in the business class 400 has an independent control system for electric steering, and the seat 100 can be individually controlled by the independent control system. This structure has been disclosed, for example, in a chair frame of an electric rotating seat 100 disclosed in publication number CN211107425U. The steering control system of the present application is implemented based on the above-mentioned prior art and related technologies.

[0026] The positions of the seats 100 are distinguished by their left and right positions in different rows, and the specific numbers of the seats 100 are obtained by combining the order in the same row. Figure 1 As shown, the present application takes a business class 400 with 6 seats 100 as an example, and the seats 100 have two rows and three columns. The seats 100 are rotatably connected to the floor of the business class 400 through a power unit and a transmission unit. In some embodiments, the motor and the transmission structure are coupled to the inside of the seat 100, but this is not limited to this. Those skilled in the art can set the position of the motor and the transmission structure according to actual driving requirements, for example, the motor and the transmission structure can be pre-buried in the floor of the business class 400. Among them, the power unit is a motor, and the transmission unit is a transmission structure.

[0027] The business class 400 also has an interactive device 200 independent of the seat 100. In some embodiments, the interactive device 200 is arranged at the end of the business class 400, so that the operator can complete the steering control of each seat 100 without approaching the seat 100. In some embodiments, the interactive device 200 is a touch screen, which interacts with the operator through graphics and / or animation, but is not limited to this. Those skilled in the art can set it according to actual control needs, for example, it can be voice control or gesture control.

[0028] The business class 400 has a control circuit 300, which is connected to the interactive device 200 and each seat 100. The present application uses a wired connection between the interactive device 200 and each seat 100, and the components of the control circuit 300 are also connected by wire. The above-mentioned connection harness is installed in the business class 400 in a pre-buried manner to improve the overall aesthetics and stability of the entire system. In some embodiments, the control circuit 300 is coupled to the interactive device 200, and the computing chip and peripheral circuit of the interactive device 200 undertake computing, storage and control functions.

[0029] The seat 100, the control circuit 300 and the interactive device 200 are powered by a power supply.

[0030] Ginseng Figure 5As shown, a steering control system for a train seat 100 includes the above-mentioned seat 100, a control circuit 300 and an interactive device 200. The interactive device 200 is configured to receive an input signal through human-computer interaction to generate an interactive signal; the interactive signal includes a mode switching signal and a seat 100 number signal pointing to the seat 100; a steering switching mode is set in response to the mode switching signal, and in response to the seat 100 number signal and the steering switching mode, the pointed seat 100 is turned; Among them, the switching modes include normal mode, guest mode and conference mode; The operation in the normal mode includes: all the seats 100 are turned to face a normal direction, which is between the train travel direction and the direction toward the adjacent window of the seat 100; The operation in the reception mode includes: the pointed seat 100 is turned to a relative state; Operation in the conference mode includes: all the seats 100 are turned to face a conference direction, and the conference direction is between the travel direction of the train and the perpendicular direction between the seats 100 and the aisle.

[0031] The touch screen displays a mode switching graphic button 220 representing the normal mode, the guest mode and the conference mode, and generates the mode switching signal in response to the electrical signal generated by the position of the mode switching graphic button 220. After receiving the mode switching signal, the control circuit 300 switches to the corresponding switching mode.

[0032] The touch screen displays a graphical user interface 201, on which a seat graphic 210 of each seat 100 is represented, and the arrangement of the seat graphic 210 corresponds to the position between the seats 100. The mapping relationship between the seat graphic 210 and the seat 100 can be determined according to the relative position between the seat graphics 210 and the marking of the seat graphics 210. An angle sensor is provided on the seat 100, and the angle sensor is in communication connection with the control circuit 300. In response to the seat 100 orientation signal generated by the angle sensor, the touch screen displays the orientation state of each seat 100 in real time. In some possible embodiments, the angle sensor is defaulted, and the control circuit 300 records the mode switching signals and the seat 100 number signals pointing to the seat 100 according to its built-in memory, and deduces the steering angle of each seat 100 according to the above-mentioned mode switching signals and the seat 100 number signals pointing to the seat 100. However, the disadvantage of this method is that there is a lack of feedback. In the case of failure of the motor or the drive structure, the display device may incorrectly deduce the angle state of the seat 100.

[0033] In some embodiments, the seat graphic 210 will also play an animation of the seat graphic 210 turning during the turning process of the corresponding seat 100 to more intuitively represent the state of the corresponding seat 100, thereby improving human-computer interactivity.

[0034] By observing and comparing the above three modes, it can be found that only the meeting mode needs to further provide the seat 100 number information to the interactive device 200. After the other two modes are output, the interactive device 200 will provide all the seat 100 number information to the control circuit 300 by default.

[0035] After switching to the meeting mode, the interactive device 200 displays a turn graphic button 230 based on the existing seat graphics 210. The turn graphic button 230 is displayed between the seat graphics 210. In response to the turn graphic button 230, the control circuit 300 generates a seat 100 number signal pointing to the seat 100 and a turn signal indicating a turn angle. The turn graphic button 230 corresponding to the meeting mode includes a first turn graphic button 231 indicating adjacent seats 100 in the same row, a second turn graphic button 232 indicating adjacent rows of seats 100 on the same side, and a third turn graphic button 233 indicating seats 100 on both sides and in the front and rear rows.

[0036] Ginseng Figure 4 , Figure 8 As shown, the control circuit 300 is configured to, in the meeting mode: in response to a signal generated at the first turn graphic button 231 or the second turn graphic button 232, generate a seat 100 number signal of the seat 100 corresponding to the first turn graphic button 231 or the second turn graphic button 232, and the relative state is that the corresponding two seats 100 are turned to face each other; in response to a signal generated by the third turn graphic button 233, generate a seat 100 number signal of the seat 100 corresponding to the third turn graphic button 233, and the relative state is that the corresponding four seats 100 are turned diagonally to each other.

[0037] After the signal at the position of the first turning graphic button 231 between adjacent seats 100 in the same row is triggered, the control circuit 300 controls the corresponding adjacent seats 100 in the same row to turn to a direction perpendicular to the length direction of the aisle; Ginseng Fig.11 As shown, after the signal at the position of the second turn graphic button 232 representing the adjacent row of seats 100 on the same side is triggered, the control circuit 300 controls the corresponding adjacent row of seats 100 on the same side to turn to a direction parallel to the length direction of the aisle and to be arranged face to face; After the signal at the third steering graphic button 233 representing the seats 100 on both sides and in the front and rear rows is triggered, the control circuit 300 controls the corresponding four seats 100 on both sides and in the front and rear rows to turn, and the four seats 100 form a quadrilateral, and the two pairs of sides of the quadrilateral have an intersection, and each seat 100 turns to face the intersection. For a left-right symmetrical layout of seats 100, the quadrilateral is a rectangle, and for a left-right staggered layout of seats 100, the quadrilateral is a parallelogram.

[0038] Ginseng Figure 3 , Figure 7 As shown, the control circuit 300 is configured to: in the conference mode, in response to the signal generated by the mode switching graphic button 220 indicating the conference mode, the control circuit 300 obtains the mode switching signal indicating the conference mode and the seat 100 number signal pointing to all seats 100, and the control circuit 300 controls the motors corresponding to all seats 100 to rotate and drive the seats 100 to turn to the conference direction. Fig.10 As shown, the business class 400 has a cabin head and a cabin tail according to the train travel direction. In some possible embodiments, the angle between the conference direction and the length direction of the aisle gradually decreases from the cabin head to the cabin tail. In the conference mode, the perspectives of each passenger are gathered and concentrated, and each seat 100 is set with a facing angle according to the distance to the cabin head, which can better ergonomics and reduce the burden on the body.

[0039] Ginseng Figure 2 , Figure 6 As shown, the control circuit 300 is configured to, in the normal direction, in response to the signal generated by the mode switching graphic button 220 indicating the normal mode, obtain the mode switching signal indicating the normal mode and the seat 100 number signal pointing to all seats 100, and control the motors corresponding to all seats 100 to rotate and drive the seats 100 to turn to the normal direction. Fig. 9 As shown, the normal direction is between the train travel direction and the direction toward the adjacent window position of the seat 100. This direction enables viewing of the external scenery through the transparent windows 410 on both sides of the business class 400.

[0040] Ginseng Figures 6 to 8As shown, the touch screen also displays a train direction switching graphic button 240 for switching the train's travel direction, and the train's travel direction is generated according to the electrical signal generated by the position of the train direction switching graphic button 240. The vehicle is driven by the front of the train during travel. When traveling from A to B, the business class 400 is pulled forward. When traveling from B to A, the business class 400 is pulled reversely, and the original tail of the cabin becomes the head of the cabin. In this case, by providing a train direction switching graphic button 240 for switching the train's travel direction, the crew can flexibly adjust the train's travel direction according to the travel direction. In response to the signal generated by the train direction switching graphic button 240, the seat 100 in normal mode, meeting mode and conference mode (normal mode in general) rotates to the corresponding direction.

[0041] The touch screen also displays an emergency stop graphic button 250 indicating an emergency stop. In response to the position of the emergency stop graphic button 250, an electrical signal indicating a shutdown is generated, and the control circuit 300 controls the power unit to shut down. The emergency stop graphic button 250 generates an electrical signal indicating a shutdown through several triggers, wherein the present application sets two triggers within a certain time range to generate an electrical signal indicating a shutdown.

[0042] The embodiments described above are only preferred solutions of the present invention and are not intended to limit the present invention in any form. Other variations and modifications are possible without exceeding the technical solutions described in the claims.
