Gypsum Wallboard Forming Device Automatically Mold Control System

The gypsum building material, universally acknowledged as a green building material, has a broad and bright future, and the wall-board made of gypsum is a typical building material, whose quality and productive efficiency depend on the performance of the shaping devices of gypsum and wall-board. Therefore, based on the existing manual or semi-mechanized devices, which are nowadays widely used in our country, this dissertation is to design a set of effective devices for shaping gypsum wall-board and a mechanized manipulative system for open model. Devoted to such kind of task, the author at the very beginning expounds the micro-level theories about the process of figuration of gypsum wall board and elaborates the law of the changing gypsum intensity while concreting as well as the law of thermodynamics. Though deep-going research the author gets the internal correlation—while the gypsum's temperature began to reduce in the concreting process, the gypsum wallboard gets so intense as required of open model ,which is the theoretical foundation of the whole dissertation. The author continues to conduct a very dedicate research on the shaping devices of gypsum wallboard, and thereafter fixes on a blueprint of the mechanized manipulative system for the shaping device of gypsum wall board and sets forth the manipulation conditions. The whole system compromises several major parts, such as the microcontroller with peripheral circuit, the temperature transducer circuit, the communication circuit.The author completes the task of designing the software and hardware according to open model control system mechanized by AVR microcontroller and at last develops a new monitoring system based on Delphi 7.0 host computer, which can remote monitor and control the mechanized manipulative system, which lays a good foundation for the large scale automatic manufacturing of gypsum wallboard in the future. This dissertation, taking the nature of gypsum as its theoretical foundation, chooses the AVR microcontroller as a major controller and meanwhile chooses DS18B20 as the temperature sensor for this automatic open model system, which enable this whole system has better performance in terms of convenience, stability and practicability. The result of the experiment with this set of system designed by the author shows that this control system greatly improves the quality of gypsum wallboard as well as its productive efficiency.
