Objective Objected To design an intelligent, safe, user-friendly baby
incubator. Methods A control circuit board for baby incubator was designed based on the MCU
P89V51RD2 after the introduction of the composition of baby incubator and the function
analysis. This control circuit board includes the sample circuit, LCD display circuit,
keyboard and other modules on the board. Results This baby incubator can realize the
sample, display, alarm and auto-dispose of emergency about the temperature and humidity in
baby incubator. After repeated experiments, it is proved that the board can run stably.
Conclusions This control circuit board for baby incubator is stable, man-machine interface
is concise and easy to be operated and maintained.
