Technical Field

The patent relates to a control system and a control method thereof, in particular to a lifting locking function of a height-adjustable table and a control method thereof, belonging to the technical field of intelligent control.

Background

Height-adjustable furniture, in particular height-adjustable tables or height-adjustable workstations, usually comprise a lower part which can be placed on a floor, an upper part and a drive. The distance between the lower part and the upper part can be adjusted by means of the actuating means.

Powered height adjustable tables typically have a control panel with buttons that allow the user to adjust the height of the table as desired. Pressing a button on the control panel may send a turn and turn time command to the motor controlling the drive.

The control panel is typically located on the left or right side of the table surface in a location that is easily accessible to the user. However, since the control panels are placed in a very easily accessible position, they are sometimes accidentally pressed by the user himself or others. This may result in the table moving from a desired height to an undesired height. This causes inconvenience to the desk user because they need to reposition the desk to a desired height. Accidental height adjustment can also cause danger and damage to the work. For families with children or pets, the self-control lifting table is inevitably controlled by the children as a toy, and certain potential safety hazards and irrationality exist for children users.

Thus, the desktop requires a locking function for locking and disabling the physical buttons on the control panel. This may prevent accidental or unnecessary height adjustments or movement of the table and reduce the risk or interference to the user due to sudden, accidental height adjustments.

If the received command is a command to adjust the table height, the desired table height adjustment is performed. If the received command is an "unlock" command, the table state will switch from "locked" to "unlocked".

3. When the control panel is in the locked state, the processor checks whether the command receives an "unlock" command. If an "unlock" command is received, the processor will execute the "unlock" command and return the locked state to "unlocked". If the received command is not an "unlock" command, the processor will ignore the received command and will not make height adjustments to the table. This effectively locks the control panel against accidental, accidental and potentially dangerous height adjustments or table movements. Further height adjustments can only be made after the user chooses to unlock the control panel from the APP on the mobile terminal device.
