Design and Testing of Silo Weighing Monitoring System
摘要
Abstract
To address the issues of significant measurement errors and insufficient automation in traditional weighing meth-ods for material silos,an STM32-based weighing monitoring system for silos was designed.The system adopted a modular architecture,with hardware comprising a main control module,A/D converter,communication module,sensor module,signal amplifier,and power supply module,enabling stable acquisition and reliable transmission of weighing signals.The host computer monitoring platform provided real-time display of weighing data,historical trend graphs,and report statis-tics,supported parameter configuration and data storage,and offered abnormal alarm and fault diagnosis functions to facil-itate maintenance management and quality traceability.To mitigate weighing fluctuations caused by material impact during unloading,equipment vibration,and uneven loading,the system employed a limiting filter algorithm to suppress glitch in-terference in the acquired signals,while establishing an error compensation model to correct systematic deviations,thereby improving the stability and consistency of weighing results.Acoording to simulation experiments,the error distribution be-tween monitoring quality and actual quality was within a narrow range of 0.12%-0.40%.Field test results indicated that the percentage error of monitored mass ranges from a minimum of 0 to a maximum of 3.43%,with an average of 1.52%,all errors between actual and monitored mass being below 4%.The system effectively alleviates the issue of overestimation due to impact forces during material fall and corrects unmeasurable phenomena caused by material suspension during feed-ing interruptions.It provides reliable feedback for coarse and fine two-stage feeding control,meeting the requirements for silo weighing monitoring and process control,and demonstrates considerable engineering application value and scalability.关键词
