AUTOMATIC CONTROL SYSTEM OF A CUTTING MACHINE AND CONTROL METHOD BASED ON MACHINE VISION AND SENSORS INTERACTION

摘要

FIELD: machine building.;SUBSTANCE: invention discloses an automatic control system of a cutting machine and control method based on machine vision and sensor interaction, consisting of the main body of the cutting machine, automatic transport system of a drill string and automatic system for attaching the drill string. Automatic transport system of the drill string due to the movement of a feed hydraulic cylinder pushes the feed platform of the drill string, which is advanced in development, with the height of the expandable drill string on the feeding platform being adjusted by means of a hydraulic lifting cylinder, and the coaxiality of the expandable drill string with respect to the working one is ensured by the presence of a displacement sensor and limit switch. Automatic drill string attachment system adjusts the position and angle of a binocular camera on charge-coupled devices using a telescopic arm-robot, adjusts the periphery of the extensible drill string with the help of a rotary motor and ensures the attachment of the extensible drill string to the working one by means of visual positioning.;EFFECT: present invention has a relatively high level of integration and high degree of automation, allows to automatically extend the drill string and conduct the process without an operator, and also increases the efficiency of coal mining by improving reliability and reducing operating costs.;10 cl, 12 dwg
