Abstract
Official abstract text for this publication.
To easily obtain a quantity of received light with computation by only measuring pulses of an electric signal related to a flame sensor, a flame detecting system is disclosed comprising: a flame sensor to detect light and a calculating device, in which the calculating device includes an applied voltage generating portion configured to generate a pulse to drive the flame sensor, a voltage detecting portion configured to measure an electric signal flowing in the flame sensor, a storing portion configured to store sensitivity parameters of the flame sensor in advance, and a central processing unit configured to obtain a quantity of received light of a flame using parameters of a known quantity of received light, a pulse width, and a discharge probability of the sensitivity parameters, and a discharge probability obtained from an actual pulse width and the measured number of discharge times.
First claim
Opening claim text (preview).
1 . A flame detecting system comprising: a flame sensor configured to detect light; and a calculating device, wherein the calculating device comprises: an applied voltage generating portion configured to generate a pulse to drive the flame sensor, a voltage detecting portion configured to measure an electric signal flowing in the flame sensor, a storing portion configured to store sensitivity parameters of the flame sensor in advance, and a central processing unit configured to obtain a quantity of received light of aflame using parameters of a known quantity of received light, a pulse width, and a discharge probability of the sensitivity parameters, and a discharge probability obtained from an actual pulse width and the measured number of discharge times. 2 . The flame detecting system according to claim 1 , wherein the applied voltage generating portion is configured to calculate a pulse width which intends to cause an arbitrary discharge probability and generate a driving pulse having the calculated pulse width for the flame sensor. 3 . The flame detecting system according to claim 1 or 2 , further comprising: a temperature sensor configured to measure an ambient temperature of the flame sensor, wherein the quantity of received light of a flame is corrected by the temperature.
