The invention discloses a control system of a lifting mechanism. According to the control system, a light reflecting structure is arranged on the lifting part; a laser range finder matched with the light reflecting structure to measure the relative reference position distance of the lifting component is arranged on the basis, position information of the lifting component is convenient to obtain, only one light reflecting structure needs to be installed on the lifting component, any electrical element does not need to be installed, and therefore a traveling cable does not need to be installed on the lifting component, and the system is simple and reliable. Other auxiliary positioning devices do not need to be installed in equipment, and equipment installation workloads are reduced; the invention further discloses a control method of the control system. Data measured by the laser range finder and encoder data are collected and compared in real time, and the reliability and positioning precision of the position value of the lifting component are guaranteed. The encoder is connected into the frequency converter, closed-loop control is achieved, the operation stability of the motor is ensured, and meanwhile the positioning precision of the lifting mechanism is further improved.
