the controller 3 is used for receiving an operation signal of the operation 2 device and a balance degree signal of the gyroscope sensor 1, and controlling the motor to rotate forwards or backwards according to the operation signal and the balance signal.
Specifically, in the actual use process, a user sends an ascending signal or a descending signal through the operator, the signal is transmitted to the controller, the controller sends a signal to the motor set, and the motor set rotates forwards or backwards to drive the lifting transmission mechanism set to ascend or descend, so that stepless adjustment is achieved. When the preset height is reached, the controller sends a stop signal to the motor set, and the motor set stops working at the moment.
At the moment, the height adjustment is finished, but the ground is uneven, so that the desktop cannot reach the level, inconvenience is brought to a user, whether the desktop is in the horizontal position or not is detected by arranging a gyroscope sensor, and if the desktop is in the non-horizontal position, the controller controls the motor corresponding to the desk to rotate forwards or backwards until the desktop reaches the level.
The controller is a control unit of the whole system, and a high-performance singlechip is used as a central processing unit, such as STM32, DSP and the like. For receiving command signals of the operator and feedback signals of the gyroscope. The processor is internally provided with a processing program which comprises a motor control algorithm and a lifting logic control program, and the program generates a corresponding control signal to drive the motor of the lifting table to move through the received signals of the operator and the gyroscope. For example, the control command is a command for lifting the lifting table, and after receiving the command, the processor generates a control signal for forward rotation for simultaneously operating four motors, so that the motors drive the table frame to lift. For example, when one side is higher than the height, the controller drives the motor in the corresponding direction to decelerate, stop or reversely rotate until the desktop is kept horizontal.
