A drive system and control method of dross box and lehr used in float glass production process is proposed. By setting redundant controllers and alternate transmission motors, a fault-tolerant drive system was constructed. Based on this hardware foundation, a control method based on redundant fault-tolerant strategy was developed. In this method, a three-layer control structure consisting of drive control layer, redundancy switching layer and speed judgment layer was established, and a redundant fault-tolerant control process was designed, ensuring a good match between the transmission speed of dross box and lehr, realizing automatic and non-disturbance switch of primary and standby transmission by judging the fault information. The drive system and control method proposed in this paper can improve the robustness of the drive system of dross box and lehr, ensure the optical properties of the high-end precision float glass, and improve the product quality effectively.
