早产儿智能水床温度控制系统设计

Design of the premature intelligent water bed temperature control system

早产儿智能恒温鸟巢式水床,相比传统的恒温箱,能够更好的模拟母体子宫环境,给早产儿一个安全舒适的成长空间。基于S3C2440和DS18B20的恒温水床控制系统,以S3C2440作为数据采集单元,数字温度传感器DS18B20作为温度检测元件,通过QT开发,设计了智能友好的人机交互界面。引入了模糊自适应控制算法,建立PID控制数学模型,实现控制精度提高。整个系统设有温度报警装置,保证了早产儿水床系统的安全性和可靠性。

The bird nest type constant temperature water bed for premature, compared to conventional oven, can simulate the womb environment appropriately and provide the premature with a safe and comfortable room. The constant temperature water bed control system based on S3C2440 and DS18B20, uses the S3C2440 as a data acquisition unit and the digital temperature sensor DS18B20 as a temperature sensing element. In this paper, by using QT development, we design intelligent and friendly man-machine interface. The whole system is provided with a temperature alarm device using the fuzzy adaptive control algorithm to build the PID control mathematical model, ensures the safety and reliability of the premature water bed system.
