Method and device for flame detection |
摘要 |
The flame detection system uses a microprocessor with a fuzzy-controller for analysis of the radiation intensity variations resulting from the flame, with signals outside a defined frequency band identified as interference signals. The mean and limit frequencies of the detected radiation are determined, with detection of periodic and non-periodic signals, the periodic signals with a mean frequency above a first given value (G1) and the non-periodic signals with a limit frequency above a second given value (G2) identified as noise signals. The first given frequency is determined from the flicker frequency of a stationary flame of min. flame size and the second given frequency lies above the first given frequency. |
