Title: Multiple visual field type flame detector
Inventor: YAMADA KOUJIROU
IPC: F23N5/08
Filed: 1985-04-16
Abstract: PURPOSE:To prevent error signals from developing by reducing the lowering of the relative light transmittances of optical fibers even when the optical fibers are bent by a method wherein graded index type optical fiber is employed as the optical fiber subject to bending work and at the same time the only one peak of transmittance is made so as to correspond to the predetermined angle of incidence. CONSTITUTION:Light signals from three visual fields 15, 16 and 17 are led through a 3-core junction fiber cable 5 to a photoelectric conversion part 10. The photoelectric conversion part 10 has a structure laminating a detector of infrared light (1-2.5mum in wavelength) to a detector of visible-near infrared light (0.4-0.9mum in wavelength) so as to detect lights with in said two wavelength regions with each of three laminated type photoelectric conversion elements in order to obtain six electric signals in total. Only the variation with the range of about 50Hz-1kHz, which is characteristic to the light signals emitted from the primary combustion zone of flame, is selectively amplified with a frequency discriminating amplifier 11, changed-over at a certain period (for example 50 ms) by a multiplexer 12, converted by an A/D converter 13 and finally introduced in a flame judging part 14 in order to judge the presence or absence of flame by whether at least one of the six electric signals exceeds the pre-set threshold value or not.
