The development has been carried out in compliance with EN60601-1 and 1-8 medical standards and the EN62304 software development standards.
FMECA and SFMEA studies help to reduce or eliminate the risk of failures.
The architecture has been designed with a RENESAS M32 microcontroller and the firmware follows the applicable MISRA C rules. PID control loops stabilise the incubator’s environmental conditions in relation to infant.
A 1MHz CAN bus provides communication between the HMI and the control board.
A control subassembly activates the different motors: a bidirectional current pump motor guides the disinfectant liquid outside, a brushless motor cuts the liquid drops into fine particles, and a DC fan diffuses the particles into the air.
A 72W BMS (Battery Management System) provides power to the system, which controls a Ni-MH battery. The one stage SEPIC output adjusts the voltage to optimize the operation of the motors.
The HMI subassembly is equipped with a 240×128 graphic display.
The product architecture is based on STM32 microcontrollers. Communication between the subassemblies is done by CAN bus. WIFI communication with an Android application allows remote switch on and control of the product.
