This invention discloses a fuzzy adaptive intelligent wiper motor control method and system based on noise evaluation. It includes an initial speed curve design module for generating an initial angular velocity curve based on the wiper operating frequency and wiping angle; an adaptive algorithm optimization module that processes real-time wiper operating data through a fuzzy logic controller, outputting speed and acceleration adjustment values; a neural network optimization module that uses a multi-layer feedforward neural network to optimize the fuzzy logic controller parameters to minimize the objective function; and a motor control module that adjusts the motor setpoint in real time based on the optimized adjustment values. This invention solves the problem of abnormal noise from automotive wipers, which is caused by excessive noise or insufficient wiping efficiency due to improper speed control. It significantly reduces operating noise, ensures that the wiping frequency meets regulatory requirements, and improves the adaptability and stability of the control system.

This utility model relates to the field of chemical pipeline technology, specifically to an anti-crystallization chemical pipeline insulation structure, comprising: a pipe body including an anti-crystallization pipeline; and a connecting mechanism including a first arc-shaped connecting plate, the first arc-shaped connecting plate acting on the surface of the anti-crystallization pipeline, and a first insulation cotton pad fixedly connected to the surface of the first arc-shaped connecting plate. This utility model, through the connection of the first arc-shaped connecting plate and the mounting block, allows the first arc-shaped connecting plate and the second arc-shaped connecting plate to be installed on the surface of the anti-crystallization pipeline, so that the connecting block is installed on the surface of the mounting block, allowing the connecting base to be inserted into the mounting block, and allowing the limiting buckle to deform and engage at the mounting block, thereby fixing the installation position of the first arc-shaped connecting plate and the second arc-shaped connecting plate for insulation treatment of the anti-crystallization pipeline. Conversely, the first arc-shaped connecting plate and the second arc-shaped connecting plate can be disassembled to ensure the insulation efficiency of the anti-crystallization pipeline.

This application discloses a lubrication and anti-overflow device for a coil drawing machine, including a coil drawing machine mold. An oil tank is provided on the lower surface of the mold, and the oil tank is connected to a circulating oil tank via a return oil pipe. An oil pump is provided on the upper surface of the circulating oil tank, and the pump is connected to two movable nozzles via an oil delivery pipe. The device also includes an oil receiving tray, which is located on the side of the oil tank away from the mold. The inside of the oil receiving tray is connected to a support roller via a support frame, and the support roller is rotatably connected to the support frame.
