This invention discloses an automatic planning method and system for spraying paths of 3D workpieces based on visual point clouds, specifically relating to the field of automatic spraying path planning technology. By constructing a spraying space coupling description set and a spraying deployment constraint index, the method achieves a quantitative characterization of the degree of restriction of spraying space in different surface areas. Combined with the safety margin of spraying distance and the adjustable range of spray gun posture, a physical accessibility assessment quantity for spraying is formed, which automatically divides the spraying area into a stable spraying area, a restricted spraying area, and a physically unsprayable area. Thus, in the path generation stage, differentiated strategies such as continuous spraying, segmented compensation, and path reconstruction are adopted for different areas, which significantly improves the coating coverage integrity, thickness consistency, and process reliability of complex 3D workpieces in the actual spraying process. It also enhances the system's adaptability to structural complexity and working condition changes in real coal mining machinery spraying sites and reduces the risk of manual repair and rework.

The invention provides a voltage control and detection circuit, a power conversion device and a charging pile, and belongs to the technical field of circuits. A detection voltage output by an operational amplifier circuit in the voltage control and detection circuit can reflect an error between a reference voltage and an output partial voltage, so that a control circuit realizes closed-loop control of the output voltage of the DC / DC conversion circuit based on the detection voltage.
