Research and Application of Hybrid Teaching Mode Based on Data Analytics In order to solve the problems of low drying efficiency,poor anti-interference ability and low degree of automation of traditional drying equipment,an intel-ligent drying control system for plastic particles with STM32 microcontroller as the core is designed in this paper,which expands the peripheral interface circuit and realizes the efficient integration of each sensor communication device.By intro-ducing the real-time operating system FreeRTOS to manage tasks,data collection,relay drive,human-machine interac-tion,alarm monitoring and other tasks can be efficiently completed.The system realizes the communication between the main control board and the industrial control screen through the RS485 bus,and combines the digital tube display and but-ton control to provide a friendly human-machine interaction interface for the operator.Through experimental verification,the intelligent drying control system for plastic particles based on STM32 can better meet the requirements of plastic par-ticle pretreatment,and has considerable market value and application prospects.
