Embodiment Construction
[0050] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.
[0051] Such as Figure 1 to Figure 10 , a discrete measurement and control online execution method is characterized in that the method comprises the following steps:
[0052] In a target shape with boundary conditions, the actual shape curve data obtained by the measurement module (1) is compared with the required target shape to obtain a control parameter Z-direction coordinate difference;
[0053] Outputting M media in unit time through the execution module (2), using the control parameters and the output volume of the media to obtain the operating speed of the control execution unit;
[0054] At different speeds, the corresponding amount of m...

The invention discloses a discrete measurement and control online execution method. In a target shape with boundary conditions, the method compares the actual shape curve data obtained by an online measurement module with the required target shape to obtain the control parameter Z-direction coordinates. difference; the execution module outputs M media per unit time, and uses the control parameters and the output volume of the media to obtain the operating speed of the control execution unit; at different speeds, execute and output the corresponding amount of media within the unit length; based on the media Filling characteristics, the topological size remains unchanged after superposition, the Z direction can be accumulated, and the X and / or Y directions have filling characteristics, so the approximation to the target shape is realized on the basis of the basic shape, and then stacked to form the target shape medium. Using this control scheme, the position distance between the measurement module and the execution module and the boundary conditions of the target shape curve are considered to realize the generation of the object medium. This control method can be applied to the fields of coating, 3D printing, and soil backfilling.
Description
technical field [0001] The invention relates to the field of testing and control in mechanical engineering, and specifically relates to a discrete measurement and control online execution method. The invention adopts a discrete method, and realizes medium stacking to obtain a target shape by combining testing technology with control technology. Background technique [0002] In recent years, with the development of science and technology, large-scale online analysis and processing capabilities have become more and more powerful. At present, the method of regular offline analysis is usually used in the production process, that is, sampling is done every few hours or at a set time, sent to the laboratory for manual analysis, and then the production is guided according to the analysis value. Due to the large time lag, it is far from meeting the requirements of online control. On-line detection technology is gradually developed in order to obtain the real-time measurement and co...
