Title: Method and device for corpuscle detection
Inventor: NISHIYAMA MASANOBU
IPC: G08B17/107
Filed: 1986-06-30
Abstract: PURPOSE:To improve detection ability and to facilitate early-stage detection, etc., by finding the difference in the detected value of a photodetector between a process wherein gas to be measured is supplied to a detection part and a process wherein clean air is supplied. CONSTITUTION:While an on-off valve 8 of a switching mechanism 12 is opened and an on-off valve 11 is closed, a suction device 6 is put in operation to guide the gas to be measured into the detection part 1 from a collection pipe 5a. Then, if particulates such as smoke are present in gas passing through an area 2 to be detected, irradiating light from a projector 3 is reflected and the quantity of scattered light is detected by a photodetector 4. The output alpha of the photodetector 4 at this time is outputted while variation beta in the small quantity of diffuse reflected light in the presence of the particulates is added. Then the on-off valve 8 is closed and the on-off valve 11 is opened to supply the clean air into the detection part 1, and consequently the gas passing through the area 2 contains no corpuscle, so that the output of the photodetector 4 is only the variation beta. Then the difference between both detected values is found to obtain the output alpha-beta based upon only the scattered light of the corpuscles, i.e., real corpuscle concentration from which the variation beta is removed.
