Problems solved by technology

Both of these two flame detectors have certain limitations: single infrared or single ultraviolet flame detectors have poor anti-interference ability, and are more likely to be affected by background light such as sunlight, heat sources, fluorescent lamps, and incandescent lamps to cause false alarms
Therefore, this type of flame detect

Abstract

The invention provides an infrared ultraviolet composite flame detector. A log amplifier is utilized to convert current from an ultraviolet photoelectric tube and an infrared photoelectric detector to enable the flame detector to detect tiny signals. A detection method of the flame detector can be further provided, and the tiny signals can be detected by utilizing the method to conduct flame detection.

Description

technical field [0001] The invention relates to the field of fire protection, in particular to an infrared-ultraviolet composite flame detector and a detection method thereof. Background technique [0002] Existing flame detectors are roughly divided into two types, one is a single infrared or single ultraviolet flame detector, and the other is an infrared-ultraviolet composite flame detector. Both of these two flame detectors have certain limitations: single infrared or single ultraviolet flame detectors have poor anti-interference ability, and are more likely to be affected by background light such as sunlight, heat sources, fluorescent lamps, and incandescent lamps to generate false alarms. Therefore, these flame detectors are only suitable for use in enclosed spaces with limited natural light. The traditional ultraviolet-infrared composite flame detector is limited by the use of ultraviolet photocells and has a long response time. Therefore, this type of flame detector...
