Design of intelligent monitoring system for infant incubator based on field programmable gate array

目的 :研制一种新型的婴儿保温箱智能监护系统,以确保婴儿保温箱的工作安全可靠。方法:使用现场可编程门阵列(field-programmable gate array,FPGA)(CycloneⅡ)芯片作为核心部件,采用双重温度控制系统方案进行设计,将多个功能模块集成到一片FPGA中,构成片上可编程系统。结果:该系统可自动监测婴儿皮肤温度、脉搏以及是否尿床,自动监测和控制箱内的温度和湿度。且仪器发生电路故障时可自动切换到强制保护电路,维持保温箱内的温度,确保婴儿生命安全。结论:该系统性能稳定、精度高、安全可靠、操作方便,具有采集速率快、便携性好、功耗小等特点,可为现代医疗监护系统提供可靠的支持。

Objective To develop an intelligent monitoring system applied to the infant incubator. Methods Field programmable gate array（FPGA） Cyclone Ⅱ chip was used as the core component, and a scheme for dual temperature control system was put forward integrating multi function modules into a piece of FPGA to form a programmable system. Results The system could monitor the skin temperature, pulse and bedwetting of the infant as well as the temperature and humidity in the incubator, which could switch up mandatory protection circuit automatically in case of electrocircuit failure in order to keep the temperature in the incubator. Conclusion The system has stable performances, high precision, high reliability, easy operation, high efficiency, high portability and low power consumption, and thus can provide support for medical monitoring system.
