Embodiment Construction

[0025] In the disclosed embodiments, simple control schemes, or more complex network-based or rule-based methods and algorithms may combine one or more sensor inputs to generate status indications for controlling fire suppression and related responses. Additionally, embodiments may provide exhaust flow control from the same set of sensor inputs. In an embodiment, at least one sensor type producing a predefined signal is used to detect fire and cooking status of the appliance, the predefined signal is applied to the controller, the controller responsively distinguishes the predefined signal in combination with other sensor signals , each of the at least two cooking states corresponds to at least two exhaust gas flow rates, implemented by the controller in response to distinguishing the two states, and the predefined signal is simultaneously used to distinguish fire situations, in response to their Differently, the same controller activates fire suppression mechanisms, such as w...

Abstract

The present invention relates to a fire safety system, particularly suitable for commercial kitchen applications, providing control over exhaust levels to improve energy efficiency and respond intelligently to fires or fire risks. In embodiments, the system may provide early warning of fire hazards or impending fires. Embodiments use probability estimates with cancelable alerts. Embodiments employing classifiers may use the use of alarm cancellation as a mechanism for supervised learning.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of U.S. Provisional Application No. 62 / 473,747, filed March 20, 2017, the entire contents of which are hereby incorporated by reference. Background technique [0003] Known fire suppression systems for use in vented hoods placed above or around a hob primarily involve delivering a flame retardant onto the cooking surface in the hood or ductwork when a temperature indicative of an open flame is measured Prevents fat or oil from burning. Existing fire suppression systems operate by measuring a fixed absolute temperature in the enclosure or ductwork and activating an alarm or releasing a flame retardant when a pre-set temperature is reached. However, this approach does not account for changes in exhaust temperature, nor does it account for the situation when it is just a conventional cooking flare rather than a fire. Additionally, fire suppression systems only detect existing fires. Th...
