3results about How to "Automatic correction" patented technology

The invention discloses an intelligent driving control method and device for heavy electric engineering equipment, and the method comprises the steps: obtaining the road surface information and road condition information in front of the equipment in real time through a road condition collection device; constructing a self-learning driving torque control model, carrying out comprehensive analysis according to the operation data and the road surface and road condition information, selecting a driving control mode suitable for the current driving working condition to analyze the power and speed feedback of a driving system, carrying out optimization decision on the output torque, and calculating to obtain a safety torque limit boundary value; meanwhile, energy scheduling is carried out on the energy consumption equipment to realize energy consumption management; and according to the safety torque limiting boundary, the maximum available torque of the vehicle, the vehicle-mounted traction motor driver and the information of the battery management system, a torque output value which is constructed and continuously corrected is transmitted to the traction motor driver through the vehicle control unit to control the permanent magnet synchronous motor to output corresponding torque. According to the invention, accurate torque output is realized, the energy efficiency, adaptability and driving safety of the whole machine are improved, and the operation difficulty of personnel is reduced.

The utility model discloses a deviation signal sensor self-control device which comprises frame bodies, an adjusting cross rod is fixedly installed between the frame bodies, a lower fixing cover is arranged on the outer surface of an electric rotating roller shaft, a driving motor is fixedly installed on the side surface of the frame bodies, a rotating lifting mechanism is arranged between the frame bodies and an electric rotating roller, and the rotating lifting mechanism is fixedly installed on the lower fixing cover. The inclination angle of the electric rotating roller is controlled through the lifting mechanism so that materials passing through the electric rotating roller can be adjusted. According to the deviation signal sensor automatic control device, after paper conveyed by an electric rotating roller deviates due to uneven thickness, a photoelectric detection switch is covered, and at the moment, a driving motor is started to drive a worm to rotate, so that a worm gear meshed with the worm rotates, a sleeve is driven to rotate, and a screw rod can move up and down; the electric rotating roller can ascend or descend, and paper materials can automatically move back along with rotation through ascending and descending of the electric rotating roller, so that the paper materials are automatically rectified.

This utility model relates to an integrated tooling for vehicle frame inspection and correction, belonging to the field of automotive manufacturing technology. It solves the technical problem that existing tooling of this type can only inspect the accuracy of vehicle frame dimensions. The tooling includes a base frame; several upper and lower fixed clamps mounted on the base frame; and several upper and lower lifting clamps, which are mounted on the base frame via a lifting mechanism. When the lifting mechanism drives the lifting clamps to move up and down, the relative positions between the lifting clamps and the upper and lower fixed clamps change. Through this structure, the tooling can not only inspect the accuracy of vehicle frame dimensions but also automatically correct deformed vehicle frames.
