Fault Tolerance and Real Time Monitoring Infant Incubator Model

Abstract

This paper present the development of fault redundant infant incubator model, the framework used here is both hardware fault monitoring and software fault monitoring. The purpose of a Fault tolerant system is to ensure that faults do not result in malfunctioning and system failure and to achieve the best performance even with minimum number of sensors working. It is developed in such a way that the hardware fault monitoring module connects the two basic functional units with separate components to a central controlling unit. This control unit performs the function of a back up to support the whole system, that is redundant Sensing for the critical parameter such as temperature and the humidity has been incorporated using triple modular redundancy. Software fault monitoring involves transmitting of information and notifying of personnel about faulty parts through the graphical user interface (GUI) during operation for better performance of the incubator. The proposed model was developed using a PIC16F688 micro controller, Temperature sensors (DS18S20), Humidity sensor (DHT11).
