Title: Photo pulse system smoke sensor
Inventor: YAMAMOTO KATSURA
IPC: G08B17/10
Filed: 1981-12-22
Abstract: PURPOSE:To provide a smoke sensor which reduces a power consumption and can make a maximum utilization of information during no production of any photo pulse, by a method wherein, when an output theory of a collecting amplifier, except a projecting time, is ''1'', a gate circuit, through which the collecting amplifier and a processing circuit are connected together, is adapted to close. CONSTITUTION:A luminous diode 2 is caused to emit light by means of an output of a pulse oscillator 1, and an output of a photoelectric converting element 3 is amplified by a collecting amplifier 4 to input it to an output deciding circuit 5 of the amplifier 4. At a normal time when smoke is absent at an optical path between the luminous diode 2 and the photoelectric converting element 3, the output the amplifier 4 produces a pulse of more than a specified value, a deciding circuit decides the absence of smoke from a pulse value, and if the output pulse of the amplifier 4 reduces to lower than the specified value due to smoke in the optical path, and deciding circuit decides the pressure of smoke and outputs a fire sensing signal. The output of the amplifier 4 is higher than 3V irrespective of the presence of smoke, and an input theory of a current exclusive- OR circuit 6 is set to ''1''. Thus, the output of the exclusive-OR circuit 6 is brought to a theory ''1'', a reverse voltage is applied to a diode 7 to bring it into OFF. That is, the output pulse of the amplifier 4 is inputted to the deciding circuit 5 to compare it with a comparison voltage, and this enables deciding of the presence of smoke.
