Problems solved by technology

Although various types of Petri net extensions have appeared to solve modeling problems in the manufacturing field, most of the modeling methods can only be used for model building and model analysis, etc. Considering that Petri net is a mathematical tool, theoretical research and simulation The significance is far greater than the actual application value, or the software and hardware platforms required for model building are too complex, and it is difficult to apply to the control system development process of the multi-operation process manufacturing system

Embodiment

[0062] Step 1: Division of structural and functional modules of the gypsum block forming production line.

[0063] The division of the structural modules of the gypsum block forming production line is based on the principle of the minimum function of the module. According to the principle of gypsum forming and the characteristics of the production line, the production line is divided into several independent functional units. The division of structural and functional modules of a gypsum block forming production line is shown in Table 1.

Abstract

A method for building a gypsum block forming production line through control flow modeling based on Petri network relates to a gypsum block production line, in particular to a method for building the gypsum block forming production line based on the Petri network. The method specifically includes the following steps: 1) dividing function modules; 2) building function module operation sequence mapping; 3) building a monitoring controller model; 4) building a control flow model based on the Petri network; 5) determining specific parameters of the control flow model; 6) building the production line. By means of the method, the gypsum block production line can be optimized through modeling, the structure of the production line is simplified, and meanwhile the working efficiency of the production line is improved.

Description

technical field [0001] The invention relates to a gypsum block production line, in particular to a method for creating a gypsum block production line based on Petri nets. Background technique [0002] Gypsum is an energy-saving and environmentally friendly material. The characteristics of the gypsum molding industry meet the current low-carbon and high-efficiency development needs. In the field of gypsum block molding, the research on molding technology and equipment has always been one of the important topics of many scientific research institutions and manufacturers. .
