The invention discloses a skew-detection-based suitcase roller control device. The skew-detection-based suitcase roller control device comprises a supply battery, a switch, a skew detection circuit, an analog-to-digital conversion circuit, a control circuit, a drive circuit and a servo motor, wherein the supply battery is used for providing electric energy; the switch is used for controlling the electric energy provided by the supply battery to be transmitted or cut off; the skew detection circuit is used for detecting skew of a suitcase to acquire an analog signal; the analog-to-digital conversion circuit is used for converting the analog signal into a digital signal; the control circuit is used for acquiring skew information according to the digital signal and generating a control signal; the drive circuit is used for outputting a drive signal according to the control signal; and the output shaft of the servo motor is fixedly connected with a connecting shaft, on which the suitcase rollers are located, through a fixing part, and the servo motor is used for generating a driving force according to the drive signal to enable the rollers to rotate. According to the skew-detection-based suitcase roller control device, power is provided by the motor, so that force consumption caused by manual pulling is reduced and the moving efficiency of the suitcase is improved.
