Standby circuit of electric lifting table

The invention provides a standby circuit of an electric lifting table, which comprises a main control chip, a motor driving module, a display module, a standby circuit, an adapter, a key and a direct current motor, and is characterized in that the adapter is connected with the standby circuit, and the key outputs control signals to the main control chip and the standby circuit respectively; the main control chip sends a control instruction to the display module and the electric driving module after receiving signals of the key and the standby circuit; the direct current motor receives a signal of the motor driving module and controls forward rotation and reverse rotation of the direct current motor to drive the table to ascend and descend; and the display module receives the control signal of the main control chip and displays the height information of the desktop. And the main control chip is a core control unit of the whole electric lifting table system and is responsible for receiving control signals from
