摘　　要：目的:研制具有强制保护电路的婴儿保温箱,以确保婴儿保温箱的工作安全可靠。方法:建立温度数据库,采用Cygnal F005单片机作为智能部件,通过对比的方法准确判断传感器的工作状态;采用双重温度控制系统,确保仪器工作在正常温度范围。仪器发生电路故障可自动切换到强制保护电路,维持保温箱内温度,确保婴儿健康。结果:新型婴儿保温箱的设计确保了电路温度控制精确,工作状态可靠,能够为新生儿提供一个空气洁净、温湿度适宜的舒适安全的环境。结论:婴儿保温箱的性能稳定,精度高,安全可靠,操作方便。Objective To develop infant thermal container with forced protection circuit so as to ensure its security. Temperature database was set in thermal container and Cygnal F005 was used as intelligent controller. The state of the sensor was judged hy comparison precisely. Double temperature controller was adopted to ensure normal working temperature. When the container went wrong, it could automatically switch to protection circuit to keep the temperature for infant. Results With precise temperature control and steady working station, the new type thermal container for infant could provide a safe and comfortable condition with clean air and fitting temperature and humidity. Conclusion The container is steady, accurate, safe and convenient.
