|
摘要
针对传统气体检测仪功能单一、可扩展性差且成本较高的问题,基于ST公司图形软件配置工具STM32CUBE,搭建一种通用智能气体分析平台。该平台兼容多种类型传感器,实现多种气体成分实时监测。通过STM32CUBE完成底层端口的参数配置,借助STM32CUBE支持的FreeRTOS操作系统,创建各应用层线程任务,根据相应的模块给出了推荐电路。设计数据滤波提高检测精度,完成平台稳定性和准确性测试。结果表明,该气体分析平台满足工业仪表的检测精度和稳定性,具有较好的使用价值。
In view of the problems of traditional gas detector,such as single function,poor expansibility and high cost,a general intelligent gas analysis platform was established through the graphical software configuration tool STM32 CUBE designed by ST Microelectronics. Various sensors can be compatible with the platform to monitor various gas components in real-time. The parameters of bottom port were configurated through STM32 CUBE,each application layer thread task was built through FreeRTOS operating system supported by STM32 CUBE,and recommended circuits were designed according to the corresponding modules. Data filtering methods were approached to improve the accuracy of detection,and the experiments to test stability and accuracy of platform were completed. The results of experiment show that the platform is satisfied with precision and stability of industrial instrument,which has good practical values.
