Video flame detection system and method for controlling a range

摘要

A video flame detection system and method for controlling a range. The system includes a video flame detector assembly coupled to an electric range and having a camera. A relay control board is coupled to the video flame detector assembly and includes a smoke contact, a flame contact, a relay module, a processor, and a memory coupled to the processor. A range control system is coupled to the relay control board and includes a control relay. When the video flame detector assembly detects smoke, the video flame detector assembly activates the smoke contact of the relay module, causing the range control system to modulate the electric current of a heating element of the range according to at least one of a first pattern or a second pattern.

1. A video flame detection system comprising:
a video flame detector assembly having a camera, the video flame detector assembly to be coupled to a range; and a relay control board coupled to the video flame detector assembly, the relay control board having a smoke contact, a flame contact, and a relay module; where, upon detection of smoke via the video flame detector assembly, the video flame detector assembly is configured to activate the smoke contact of the relay module, causing a range control system to modulate the electric current of a heating element of a range according to at least one of a first pattern or a second pattern, and where the first pattern includes applying the electric current to the heating element for a first period of time T1 and then removing the electric current applied to the heating element for a second period of time T2, the first pattern continuing for a third period of time T3, wherein the first period of time T1 is greater than the second period of time T2.
