多功能组合秤控制系统设计及优化算法研究
|
摘要
针对称重物品形状不规则、质量不均匀造成的称重精度下降及效率低问题,设计开发一款基于STM32单片机的嵌入式多功能组合秤控制系统。该系统引入模块化的设计理念,采用集散控制方式。硬件方面分别对系统的电源模块、主控模块、AD数据采集模块、步进电机驱动模块进行了电路的规范化设计。软件方面通过建立嵌套函数以及对组合算法的优化,提高了组合的效率和合格率。经现场测试,组合速度在65包/min时误差能控制在0.5%以内,达到预期效果。
Aiming at the problem of weighing accuracy and low efficiency caused by irregular shape and uneven quality of weighing objects, an embedded multi-function combination scale control system based on STM32 single-chip microcomputer was designed and developed. The system introduces a modular design concept and adopts distributed control. The hardware is standardized on the power module, main control module, AD data acquisition module and stepper motor drive module of the system. The software aspect improves the efficiency and yield of the combination by establishing nested functions and optimizing the combination algorithm. After field test, when the combined speed is controlled within 0.5%/min, the error can be controlled within 0.5% to achieve the desired effect.
