The method, the device and the storage medium for controlling the position of the display screen provided by the embodiment of the application are specifically described through the following embodiments, and the method for controlling the position of the display screen in the embodiment of the application is described first.

The display screen position control method of the present application can be applied to the client 100 of the display screen control system, and the client 100 can be used in a plurality of general-purpose or special-purpose computer system environments. For example: personal computers, server computers, hand-held or portable devices, tablet devices, multiprocessor systems, microprocessor-based systems, set top boxes, programmable consumer electronics, network PCs, minicomputers, mainframe computers, distributed computing environments that include any of the above systems or devices, and the like. The application may be described in the general context of computer-executable instructions, such as program modules, being executed by a computer. Generally, program modules include routines, programs, objects, components, data structures, etc. that perform particular tasks or implement particular abstract data types. The application may also be practiced in distributed computing environments where tasks are performed by remote processing devices that are linked through a communications network. In a distributed computing environment, program modules may be located in both local and remote computer storage media including memory storage devices.

It should be noted that, referring to fig. 1, the display control system includes a client 100, a display 200, and a driving member for controlling movement of the display 200, where the client 100 and the driving member are communicatively connected to issue a control command to the driving member. Each client 100 may manage a plurality of display screens 200, thereby achieving centralized management of the display screens 200.

For example, referring to fig. 1, the client 100 is communicatively connected to the display 1, the display 2, and the display 3, and when the display 1 needs to be controlled, the display 1 is a target display, and the client 100 may perform position adjustment on the target display.

Specifically, referring to fig. 2, the display screen position control method according to the present application includes:

step S100, determining a target display screen;

step 200, acquiring preset enabling states of a plurality of control modes; the plurality of control modes comprise a key control mode, a face control mode and an internal instruction control mode; the priority of the key control mode is higher than that of the face control mode, and the priority of the face control mode is higher than that of the internal instruction control mode;

step S300, determining a target control mode according to the priority and the enabling state of the control mode;

step S400, according to the target control mode, the position of the target display screen is adjusted, wherein the position comprises at least one of height, horizontal rotation angle or elevation angle.

Therefore, by setting three control modes for each target display screen, the key control mode, the face control mode and the internal instruction control mode can be respectively selected according to the actual application scene, so that the automatic control of the display screen 200 can be realized. Meanwhile, by setting priorities for the plurality of control modes, the display screen 200 can be automatically controlled and automatically controlled in the plurality of control modes under the condition that the plurality of control modes are enabled according to expected application scenes, so that the comfort of offices is improved.

It should be noted that the target display screen is the display screen 200 that is currently required to be subjected to position adjustment.

It should be noted that, the key control mode is automatic adjustment of the key triggered position, and the face control mode is automatic adjustment of the tracked face position; the internal instruction control mode is to carry out cyclic movement adjustment according to a space target position preset in the system.

It should be noted that, when the enabling state of the plurality of control modes is enabled, the control mode with the highest priority is the target control mode, and, by way of example, when the key control mode and the face control mode are enabled, the key control mode is the target control mode, and when the face control mode and the internal instruction control mode are enabled, the face control mode is the target control mode.

It should be noted that, referring to fig. 3, the display screen 200 is connected to a display stand 300, the display stand 300 includes a base 320, a sleeve 310, a horizontal rotation assembly, an elevation rotation assembly, and a lifting assembly, the elevation rotation assembly is connected to the display screen 200, the horizontal rotation assembly and the lifting assembly are encapsulated in a containing space formed by the base 320 and the sleeve 310, the horizontal rotation assembly is used for controlling the rotation of the sleeve 310 relative to the base 320, the lifting assembly is used for controlling the elevation rotation assembly to move up and down relative to the sleeve 310 to control the height of the display screen 200, and the elevation rotation assembly is used for adjusting the elevation angle of the display screen 200; so that the position of the target display screen can be adjusted.

It can be understood that the target control mode is a key control mode, and step S400 of adjusting the position of the target display screen according to the target control mode includes:

responding to a first key instruction from a user, performing instruction hysteresis operation when a key corresponding to the first key instruction is in a pressed state, and stopping movement of the target display screen when the key corresponding to the first key instruction is in a released state; the first key instruction is one of an up-shift instruction, a down-shift instruction, a horizontal forward-rotation instruction, a horizontal overturning instruction, an elevation forward-rotation instruction and an elevation reversing instruction;

after the command hysteresis operation is performed, when the key corresponding to the first key command is still in a pressed state, the control target display screen moves along the control direction corresponding to the key at a preset control speed;

after the command hysteresis operation is performed, when the key corresponding to the first key command is in a released state, the position of the target display screen is not adjusted.

It should be noted that, the instruction hysteresis operation means to extend the preset first duration. The redundant control caused by the erroneous operation can be reduced by setting the instruction hysteresis operation.

It should be noted that, when a plurality of first key commands are generated at the same time, the first key commands do not respond.

It should be noted that, the display screen 200 may be stopped at a position desired by the user by the above-mentioned key operation.

It is understood that the method further comprises:

responding to a second key instruction from a user, and storing the current position of the target display screen as a space target position; the space target position is obtained through a first key instruction;

and taking the space target positions obtained through the first key instruction as position nodes in the moving track of the internal instruction control mode.

For example, if a space target position is obtained through the first key instruction, the display screen 200 automatically reads the space target position after entering the internal instruction control mode when being started automatically next time, so that the display screen 200 can be stopped at the space target position in the initial state, and the convenience of use of a user is further improved. When a plurality of space target positions are A, B, C, D, the space target positions can circularly move among the four points.

It can be understood that, the target display screen performs position adjustment through three driving members, the target control mode is a face control mode, and step S400, according to the target control mode, adjusts the position of the target display screen, including:

acquiring face information;

verifying whether the face information is legal or not, and calculating a space target position when verifying that the face information is legal;

generating first motion tracks corresponding to the three driving pieces one by one according to the current position and the space target position;

and adjusting the corresponding driving piece according to the first motion track to enable the target display screen to be subjected to position adjustment.

It should be noted that, by judging the validity of the face, the control of the display screen 200 can be performed in the dimension of the user, so as to reduce the probability of misjudging the face to adjust.

It should be noted that, referring to fig. 3, the three driving members are a horizontal rotation assembly, an elevation rotation assembly, and a lifting assembly, respectively. By constructing a first motion profile for each driving member, it is made possible to independently operate, thereby facilitating control.

It should be noted that, in the present application, the control start time and stop time of each driving element are not limited, that is, the three driving elements may synchronously execute the first motion track, or may asynchronously execute the corresponding first motion track.

It is understood that the first motion trajectory includes a second motion trajectory, a third motion trajectory, and a fourth motion trajectory; according to the current position and the space target position, generating first motion tracks corresponding to the three driving pieces one by one, wherein the first motion tracks comprise:

projecting the current position and the space target position to an X axis, a Y axis and a Z axis respectively to obtain first starting point end point information on the X axis, second starting point end point information on the Y axis and third starting point end point information on the Z axis;

obtaining a second motion trail according to the first starting point and ending point information; the second motion track is used for determining a motion track of the target display screen for horizontal rotation;

obtaining a third motion trail according to the second starting point and ending point information; the third motion track is used for determining a motion track of the target display screen for performing elevation rotation;

obtaining a fourth motion trail according to the third starting point and ending point information; the fourth motion track is used for determining a motion track for lifting the target display screen.

It should be noted that, for the horizontal rotation component, when the horizontal rotation component rotates 180 degrees, a unique coordinate is mapped on the X-axis, for the elevation rotation component, a unique coordinate is mapped on the Y-axis during adjustment of the elevation angle, and for the elevation rotation component, a unique coordinate is mapped on the Z-axis during adjustment of the elevation angle. Therefore, the second movement track, the third movement track and the fourth movement track corresponding to the X axis, the Y axis and the Z axis are obtained by projecting the current position and the space target position in the X axis, the Y axis and the Z axis, so that all driving pieces can run independently and the running efficiency is higher.

It should be noted that, in some embodiments, the second motion track, the third motion track and the fourth motion track may be planned by a linear interpolation method, and in other embodiments, the second motion track, the third motion track and the fourth motion track may be planned by a curve interpolation method, which is not limited in this embodiment.

It is understood that the method further comprises:

acquiring an anti-fatigue strategy;

and controlling the movement of the target display screen according to the anti-fatigue strategy so as to adjust the sitting posture of the user.

It should be noted that the anti-fatigue strategy may be applied to a plurality of control modes, or may be applied to only a face control mode, and is preferably applied to the face control mode. The anti-fatigue strategy may be set to the display periodically side-to-side, up-and-down, and pitch motion. Or the position adjustment of the display screen 200 can be set to be recovered to follow the face position after the preset second time period is adjusted along a certain angle.

It can be understood that the target control mode is an internal command control mode, and step S400 of adjusting the position of the target display screen according to the target control mode includes:

acquiring a plurality of space target positions stored in a target control mode;

and adjusting the position of the target display screen according to the plurality of space target positions so that the target display screen circularly moves among the plurality of space target positions.

It should be noted that, in some embodiments, the internal command control mode is enabled by default, so that when the display screen 200 is powered on and used, the key control mode and the face control mode are not enabled, and the position of the key control mode can be adjusted according to the spatial target position set in the system. The space target position can be obtained by adjusting the key control mode according to the actual use habit of a user in the use process, or can be preset in the system. In this regard, the embodiments of the present application are not so limited. When there are multiple spatial target positions, the cyclic movement is performed among the multiple spatial target positions.

For example, assume that 4 spatial target positions, L1, L2, L3, L4, respectively, are saved in the target control mode. Then L1, L2, L3, L4 are performed periodically to effect a circular movement.

It will be appreciated that the method further comprises at least one of:

acquiring a driving state of a driving piece of a driving target display screen, and performing early warning according to the driving state;

and calculating the success rate of face recognition and carrying out early warning according to the success rate.

In this case, the drive state, such as a mechanical jam, is to be triggered by a high drive torque.

It should be noted that, in some embodiments, when the display screen 200 is started, it is first determined whether there is an early warning, if so, alarm clearing is attempted and detection is again performed, and if there is still an alarm after detection, a power-off check is performed. When there is no alarm, steps S200 to S400 are performed.

For example, referring to the embodiment shown in fig. 4, after the client 100 detects that the target display screen is powered on, it determines whether an alarm exists, and if not, it indicates a ready state, and at this time, referring to step S200, it sequentially determines the key control mode, the face control mode, and the enable state of the internal command control mode, and performs manual key adjustment when the key control mode is enabled; and when the key control mode is enabled, entering a face following adjustment mode. When the key control mode and the face control mode are not enabled, enabling the internal instruction control mode, and adjusting according to the internal position. Meanwhile, limit detection is performed during the control process of the display screen 200 to detect the driving state of the driving piece, and when the overrun alarm is released, the alarm is cleared.
