IPC: G08B17/06
Filed: 2010-05-24
Abstract: PROBLEM TO BE SOLVED: To provide a fire detector in which probability of smoke density estimation does not decrease due to an influence of temperature changes in acoustic cell.SOLUTION: The fire detector comprises, in a signal processing section 4, a path length correction section 49 that corrects a propagation path length which is used for calculation of sound velocity by a sound velocity measurement section 47. The path length correction section 49 corrects a propagation path length of ultrasonic waves based on a variation amount of the propagation path length due to thermal expansion of an acoustic cell obtained by a variation amount measuring part 48. Since sound source parts 1a and 1b and wave receiving elements 3a and 3b are fixed, the acoustic cell determines a relative positional relationship between the sound source parts 1a and 1b and the wave receiving element 3a and 3b. The path length correction section 49 corrects the propagation path length by multiplying a default value of the propagation path length by a correction coefficient represented by 1+K*ΔTc using a variation amount ΔTc from a predetermined reference temperature of the acoustic cell and a predetermined thermal expansion coefficient K.
