摘要
针对现有的液体液面监测系统需要直接接触被测液体,或者需要通过相关射线进行监测和预警,基于STM32处理器、非接触式液位传感器、Wi-Fi模块、A9嵌入式开发实验箱及手机终端等,设计了一个液面监测自动报警系统。实验表明:该系统响应及时、可扩展性强,可以应用于医疗领域,用作智能输液报警器,而且通过无线通信模块接入互联网,液体液面的监测和报警变得方便快捷。
Aiming at the problem that current monitoring systems require either a direct contact with the liquid or certain types of rays to detect the liquid level for early warning, this paper proposes an automatic liquid level alarm system based on STM32 processor, non-contact liquid level sensor, Wi-Fi module, A9 embedded development experimental box and mobile phone terminal. Experiments show this system has advantages of timely responsiveness and extensibility. For medical use, it can server as a smart infusion alarm. Particularly, the system can access the internet via a Wi-Fi module, which implements an easy way for automatic liquid level monitoring and alarming.
