With reference to fig. 1, this embodiment provides a control method of a desk board control system, which is used for controlling the desk board control system according to any one of the technical schemes of embodiments 1 to 8, and includes the following steps: the gyroscope gravity sensing module 1 feeds back parameter information of the table posture change obtained by real-time monitoring to the controller; the controller judges whether the desk surface is in a horizontal position or not according to the received parameter information; if the desk surface is not in the horizontal device, the controller respectively sends corresponding correction parameter information to the driving motor control module 29, the rotating motor control module and the lifting motor control module to control the running states of the driving motor, the rotating driving motor 7 and the lifting driving motor 8 in the desk shell; if the gyroscope gravity sensing module 1 detects that the desk surface is in the horizontal position, the driving motor control module 29, the rotating motor control module and the lifting motor control module respectively control the corresponding driving motor, the rotating driving motor 7 and the lifting driving motor 8 in the desk shell to stop running.

When the desk top is actually used, when the desk top surface on the desk top shell 37 is required to be unfolded, a user starts an opening button on the control screen 35, a controller module 36 is started, the controller module 36 releases the triggering signals of the position sensing module 34, the rotary position sensing module 18 and the lifting position sensing module 23 in the desk top shell, the rotary driving motor 7 is controlled to rotate and adjust according to the modified parameter signals, the rotary driving motor 12 is driven to rotate in the corresponding direction until the reset sensing protrusion on the movable disk 12 is aligned with the rotary position sensing module which is arranged on the fixed disk 11, the rotary position sensing module 18 generates a signal and feeds back the signal to the controller, if the parameter signals are not fed back to the controller, the controller sends out a modified parameter signal to the rotary motor control module according to the pre-stored instant data of the gyroscope gravity sensing module 1, the rotary driving motor control module is controlled to rotate and adjust until the reset sensing protrusion on the movable disk 12 is aligned with the rotary position sensing module which is arranged on the fixed disk 11, the controller receives the command signal from the gyroscope sensing module, and the controller module sends out a gesture-changing command to the gyroscope control module 1 according to the modified parameter signals, and the gesture-changing command is sent out a corresponding command to the gyroscope control module, and the gyroscope control module is controlled to send a gesture-changing command to the gyroscope control module 1; then, the process is carried out, the driving motor control module 29 for obtaining the signal instruction controls and controls the driving motor in the desk plate shell to rotate positively, and the hinge assembly 5 is in transmission connection with the driving motor in the desk plate shell and is used for driving the desk plate shell 37 to rotate relative to the desk plate base 3; so the hinge assembly 5 rotates clockwise relative to the desk plate shell 37 under the drive of the drive motor in the desk plate shell, and the hinge assembly 5 moves upwards relative to the desk plate base 3 at the same time, and the desk plate shell 37 stretches outwards relative to the desk plate base 3 under the drive of the hinge assembly 5; meanwhile, the lifting motor control module for obtaining the signal instruction controls the lifting drive motor 8 to rotate positively, and as the lifting drive motor 8 is in transmission connection with the lifting assembly 2 and is used for driving the lifting assembly 2 to do lifting motion, the lifting assembly 2 moves upwards relative to the table base under the drive of the lifting drive motor 8, and as the rotating disc assembly 4 is fixedly connected with the lifting assembly 2 and the rotating disc assembly 4 is connected with the hinge assembly 5, the rotating disc assembly 4 moves upwards relative to the table base along with the lifting of the lifting assembly 2, so that the whole table shell 37 is driven to move upwards; when the table surface on the table shell 37 is adjusted to move to a horizontal position, and when the gyroscope gravity sensing module 1 in the table shell 37 detects a signal of the horizontal position or when a front passenger greatly adjusts the angle of a seat backrest according to comfort level, the gyroscope gravity sensing module 1 feeds back instant angle change parameters to a controller when the vehicle passes through complex limit road conditions such as a rugged road surface, the controller sends out correction parameter signals to the driving motor control module 29, the driving motor control module 29 controls the driving motor in the table shell to correct the running state so as to offset the loss of the horizontal posture of the table surface due to the angle change of the backrest and ensure that the table surface is in the horizontal posture in real time, if the upper limit position sensing protrusion on the position sensing disc 33 is aligned with the origin of the sensing area of the table shell position sensing module 34 arranged on the inner side of the table shell 37 in the compensation correction process, the table shell position sensing module 34 is triggered to generate trigger protection signals, and when the protection signals are fed back to the controller, the controller instantly controls the driving motor control module 29 to control the driving motor in the table shell to stop running; meanwhile, when the rotating disc assembly 4 and the lifting assembly 2 are driven by the lifting driving motor 8 to rise to a height value controller pre-stored in the controller, a signal is sent to the lifting motor control module, and the lifting motor control module controls the lifting driving motor 8 to be driven to stop running; at this time, the table surface of the table shell 37 is completely unfolded and is in a horizontal position and a proper height, and the table surface of the table shell 37 is available for passengers;

When the desk surface is in a normal working state, when the angle of the backrest changes or the vehicle encounters a sharp turn, a convex-concave road surface, a deceleration strip and a vehicle body in the running process, the integral posture of the desk shell 37 changes, at the moment, the gyroscope gravity sensing module 1 is converted into corresponding electric parameters according to the detected posture change and fed back to the controller, the controller respectively controls the driving motor control module 29, the rotating motor control module and the lifting motor control module to send corresponding correction command parameters in the same time according to the signals, and then the driving motor control module 29 and the rotating motor control module respectively control the corresponding driving motor, the rotating driving motor 7 and the lifting driving motor 8 in the desk shell to synchronously and cooperatively and rapidly correct the working state according to the corresponding correction command parameters until the desk surface on the desk shell 37 is in a horizontal position and the desk surface is at a proper position from a carriage;

when the desk is not needed, a user starts a closing button on a control screen 35 and starts a controller module 36, the controller module 36 firstly sends a signal instruction of resetting self-checking of a rotating assembly 4 to a rotating motor control module, if a resetting sensing protrusion on a movable disc 12 is aligned with a rotating position sensing module arranged on a fixed disc 11, the rotating position sensing module 18 generates a signal and feeds back the signal to the controller, the controller receives the feedback signal, if the parameter signal is fed back to the controller, the controller sends a corrected parameter signal to the rotating motor control module according to the pre-stored initial angle information parameter and instant data of a gyroscope gravity sensing module 1 stored by the controller, the rotating motor control module controls a rotating driving motor 7 to rotate and adjust according to the corrected parameter signal, then drives the movable disc 12 to rotate in a corresponding direction until the resetting sensing protrusion on the movable disc 12 is aligned with the rotating position sensing module arranged on the fixed disc 11, the rotating position sensing module generates a signal and feeds back to the controller, the controller simultaneously sends a feedback signal to the driving motor control module 29, the gyroscope sensing module 1, the desk is reversely rotated relative to a shell 37 of the rotating motor control module, the rotating assembly is driven by the rotating table 5, the rotating assembly is driven by the rotating assembly 5, and the rotating assembly is driven by a shell 37 to move in a state of the rotating assembly, and the rotating assembly is rotated relative to a shell 5, the desk plate shell 37 is driven by the hinge assembly 5 to make inward retracting movement relative to the desk plate base 3; meanwhile, the lifting motor control module for obtaining the signal instruction controls the lifting drive motor 8 to reversely rotate, and as the lifting drive motor 8 is in transmission connection with the lifting assembly 2 and is used for driving the lifting assembly 2 to move downwards, the lifting assembly 2 moves downwards relative to the table base under the drive of the lifting drive motor 8, and as the rotating disc assembly 4 is fixedly connected with the lifting assembly 2 and the rotating disc assembly 4 is connected with the hinge assembly 5, the rotating disc assembly 4 moves downwards relative to the table base along with the descending of the lifting assembly 2, so that the whole table shell 37 is driven to move downwards, and when the table shell 37 descends to the lowest height position relative to the table base 3, the lifting position sensing protrusion 24 on the sliding block 22 is exactly aligned with the origin of the lifting position sensing module 23 arranged at the lower end of the sliding rail 21; the lifting position sensing module 23 generates a signal and feeds the signal back to the controller, the controller sends the signal to the lifting motor control module, and the lifting motor control module controls the lifting driving motor 8 to stop running, and the descending process is finished; when the lower limit sensing protrusion on the position detecting disc 33 is just opposite to the origin of the sensing area of the position sensing module 34 in the desk plate shell mounted on the inner side of the desk plate shell 37, the position sensing module 34 in the desk plate shell is triggered to generate a signal and feed back to the controller, the driving motor control module 29 is controlled to control the driving motor in the desk plate shell to stop running, at this time, the desk plate shell 37 is completely retracted into the desk plate base 3, and the whole retraction process is finished.

Therefore, the control method in this embodiment feeds back the real-time monitoring data provided by the gyroscope gravity sensing module 1 to the controller, and the controller outputs correction command parameters to the driving motor control module 29, the rotating motor control module and the lifting motor control module simultaneously to control the running states of the driving motors, so that the table surface always maintains the horizontal posture under the cooperative operation of the driving motors.
