Development of a Detection Algorithm for Kitchen Cooktop Ignition Prevention
Amy Mensch, Anthony Hamins, Kathryn Markell
A small number of previous studies focused on cooktop fire sources and considered multi-detector sensing of pre-ignition signatures in a kitchen environment. Johnsson conducted a series of experiments investigating the feasibility of distinguishing between normal cooking activities and preignition conditions using a variety of sensors in a mock kitchen  with a closed door. Sensors were placed above the cooktop and on the compartment ceiling. Signals from alcohol, CO, and hydrocarbon sensors showed potential to predict ignition while discriminating from normal cooking . Nearly all the experiments were conducted with the range hood off and the effects of room configuration and transport likely played a significant role in the interpretation of results. Jain et al. conducted cooking oil autoignition experiments, considering the effectiveness of various inexpensive sensors to detect pre-ignition conditions . Jain et al. reported that the rate of change of the moving average of the CO concentration was a robust indicator of impending ignition. The study, however, did not consider normal cooking or common nuisance sources. The objective of this study was to determine which sensors/sensor combinations showed potential for use as detection algorithm for cooktop ignition prevention. The initial set of experiments were focused on sensor response and were designed to avoid transport considerations.
