面向智能包装的温度液位监控模块设计

目的从智能包装的定义出发,研究信息型智能包装的温度液位监控模型。方法通过智能包装的定义,设计出以AT89C52单片机为核心,加入电源模块、温度传感器、液位传感器以及自动控制加热模块,并举出具体实例——多功能保温奶瓶的设计。将温度液位监控模块应用到奶瓶的包装上,利用奶瓶的保温层空隙,将数据线嵌入,单片机的输出通过数据线传输到奶瓶盖上端镶嵌的LCD1602显示屏中。结论通过该方法,用户可以在奶瓶盖的显示屏及时观察牛奶的温度和剩余量,实现奶瓶的智能包装。

The Design of Temperature and Liquid Level Monitoring Module for Intelligent Packaging

The work aims to study the temperature and liquid level monitoring model of information-based intelligent packaging starting from the definition of intelligent packaging. Through the definition of intelligent packaging, a multi-function insulated milk bottle was designed, with AT89C52 CSM as the core, and added with power module, temperature sensor, liquid level sensor and automatic control heating module; and the specific practical examples were given. The temperature and liquid level monitoring module was applied in the bottle packaging. The data line was embedded by means of the insulation layer gap of the milk bottle, and the output of the single chip microcomputer was transmitted to the LCD1602 display screen mounted on the top of the bottle lid by the data line. The proposed method enables the user to timely observe the temperature and residual quantity of milk on the display screen of the bottle lid, and the intelligent packaging of the bottle can be realized.
