HEAT STRESS RISK PREDICTION BY USING BAYESIAN NET MODEL WITH SENSOR NETWORK

With advancement in use of automation system, it is also desired to be able to know about the susceptible risk in advance for taking the preventive measures either automatically or manually. Disaster management is such an area where operatives wearing the suits and performing the activities are prone to the risk of heat stress which may cause mental impairments along with other serious effects leading to death. Such type of risk occurs in human body by not being able to compensate the heat generated into the surrounding air. The paper presents the concept of mechanism which can be used to prevent such situation by activating an alert to the operative or invoke cooling mechanism automatically before onset of the risk. The Bayesian Network Model is used to predict the onset of the risk. The model is based on the probabilities gives flexibility and simplicity in modeling the system. The system was trained with appropriate data and then compared with the real time parameters to check whether possibility of risk or not. Only those body parameters are considered which directly or indirectly participate in indicating heat stress or its onset.
