Self check-type flame detector

A self check-type flame detector, comprising:

• a casing provided with a monitoring window formed therein;
• a reflective surface fastened to the casing and located outside the casing;
• a wavelength generation unit disposed inside the casing and configured to generate a wavelength in a direction of the reflective surface through the monitoring window;
• a wavelength detection element disposed inside the casing and configured to detect a wavelength reflected from the reflective surface through the monitoring window;
• a comparison unit provided with a wavelength database (DB) for storing intensity of a reference wavelength and configured to determine whether the monitoring window has been contaminated by comparing intensity of the wavelength detected by the wavelength detection element with that of the reference wavelength stored in the wavelength DB;
• a display unit located outside the casing and configured to display a state of the monitoring window determined by the comparison unit;
• and
• a communication unit disposed inside the casing and configured to receive operation information for the wavelength generation unit from outside of the casing, to provide the operation information to the wavelength generation unit and to transmit the intensity of the wavelength detected by the wavelength detection element, or a normal signal or a contamination signal of the monitoring window determined by the comparison unit, to outside of the casing.

A self check-type flame detector, comprising:

• a casing provided with a monitoring window formed therein;
• a light emitting unit disposed inside the casing and configured to generate light in a direction of the monitoring window;
• a camera disposed inside the casing and configured to capture the monitoring window;
• a turbidity comparison unit provided with a turbidity database (DB) for storing turbidity of a reference image that is used to determine contamination of the monitoring window, the turbidity comparison unit determining whether the monitoring window has been contaminated by comparing turbidity of an image captured by the camera with the turbidity of the reference image stored in the turbidity DB;
