Real-time environmental monitoring and feedback control technology for mold cav-ity driven by single-chip microcomputer in high-precision injection molding
摘要
Abstract
In high-precision injection molding,real-time perception and closed-loop control of the mold cavity environment(especially pressure)are crucial for ensuring the quality of micro precision parts.However,existing systems generally suffer from problems such as high response delay,weak adaptability to multiple working conditions,and lack of active feedback capability.In response to the above challenges,this article proposes and implements a real-time monitoring and feedback control system for the cavity environment driven by a microcontroller.The system is based on AT89C51 to build a low-power and scalable hardware platform for data acquisition and processing,integrating four pressure sensors and real-time A/D conversion modules.The system is based on the screw position and pressure signal of the injection molding machine.Firstly,principal component analysis(PCA)is used to reduce the dimensionality of the data.Then,statistical modulus(SP)is used to simplify the data structure and avoid complex data preprocessing.Support vector data description(SVDD)algorithm is used to solve multimodal problems.Simulation experiments show that this system effectively reduces data dimensionality and improves the accuracy and efficiency of cavity environment monitoring.关键词
