Control system for electric lifting desk and electric lifting desk

A control system for an electric lifting desk, wherein the electric lifting desk comprises at least one column, and the control system comprises:

• a controller, wherein the controller comprises a microprocessor, a measured voltage acquisition circuit and a measured voltage acquisition terminal, wherein an input of the measured voltage acquisition circuit and an output of the measured voltage acquisition circuit are connected to the measured voltage acquisition terminal and the microprocessor, respectively;
• and
• a motor driver circuit configured to drive lifting of the at least one column, wherein the motor driver circuit comprises a measured voltage generation circuit and a measured voltage output terminal, and an output of the measured voltage generation circuit is electrically connected to the measured voltage output terminal;
• wherein the measured voltage generation circuit is configured to output a different value of a measured voltage in a case of at least one of a different number of columns of the electric lifting desk or a different column type of the electric lifting desk;
• wherein the measured voltage acquisition terminal is electrically connected to the measured voltage output terminal;
• and the microprocessor is configured to determine, according to a voltage signal provided by the measured voltage acquisition circuit, whether the controller is connected to the motor driver circuit and determine at least one of the number of columns of the electric lifting desk or the column type of the electric lifting desk.
