氡溶液快速制备装置的控制系统研究

Research on Control System of Radon Solution Rapid Preparation Device

氡是无色无味、具有放射性的惰性气体,易溶解于水和多种有机溶液,可以通过饮食进入人体。氡溶液用途十分广泛,常用于医学、勘探、生态保护等各个领域。针对氡溶液制备效率低下的问题,基于氡溶解动态特性的研究,提出一种以STM32为主控制器的氡溶液快速制备控制方法,通过控制温度、磁石转速两个溶氡参数达到氡溶液快速制备的目的,并对比实际氡溶液浓度与目标氡浓度,评估该控制方法。结果表明,使用该方法制备氡溶液的速率比自然溶氡速率提高23倍以上,且氡溶液制备误差不超过±15%。

Radon is a colorless,odorless,radioactive inert gas,easily dissolved in water and a variety of organic solutions,and can enter the human body through diet.Radon solution is widely used in medicine,exploration,ecological protection and other fields.Aiming at the low preparation efficiency of radon method solution,based on the study of radon dissolution dynamic characteristics,a control method for rapid preparation of radon solution with STM32 as the main controller was proposed.Two radon dissolution parameters,temperature and magnet speed,were controlled to achieve rapid preparation of radon solution.The control method was evaluated by comparing the actual concentration of radon solution with the target concentration.The results show that the preparation rate of radon solution by this method is 23 times higher than that of natural radon solution,and the preparation error of radon solution is not more than±15%.
