Steel Pipe Three-tier Production Process Of The Pe Anti Intelligent Control Strategy

In this paper, a control system that the automatic monitoring system of computer replaces manual production system is presented, in which restrict 3-layer PE outside antiseptic industrial development of steel pipe. The unfavorable factors contain complicated production technology and wayward product quality, etc.First of all, on the basis of analyzing performance index of 3-layer PE anticorrosion, technological process and operational environment, this paper advances the synthetic control schemes that have constant compound control of temperature and feedback control of speed. Considering the production process of the 3-layer PE, because it is affected by colloidized time of FBE, relatively strong coupling exists between the temperature and speed. Through the rational matching and simplifying of the variable, the system realizes uncoupling. According to the theory of conducting heat and theory of mid-frequency reaction and so on, the paper still puts forward the method to set up theory model of steel pipe conducting heat. Verified actually, the method is scientific and practical. In addition, at this strong coupling, heavy inertia, non-linear, uncertain system, it initial proposes and adopts multi-mode segmented intelligent fuzzy control strategy. The control strategy was carried on the simulation experiment by the data making through producing the scene, having made the good control result. Considering still that change of environmental temperature impacts on temperature of steel pipe, in which FBE is colloidized, it put forward the method of adjusting temperature setting value according to environmental temperature. Simulation has proved the validity of this method.According to above-mentioned schemes, we have already been developed and designed the Automatic Monitoring Computer Control System of the anticorrosive pipeline, regarding Kingview6.01 as the developing platform, and using the configuration of the software and hardware to realize communication of multi-equipment, and making virtual cartoon for technological process of scene. This system has already been run for more than one year in JingBian steel pipe antiseptic factory of exploration bureau of ChangQing petroleum. It was reliable steady and advanced by the test of scene. The product was test by synthetic laboratory of Chinese petroleum pipeline company pipeline research center. Product quality far goes beyond the standard of SY/T4013-95. And it is also the first pipeline using the configuration software by us and designed in the research domain.
