Title:
MICROPARTICLE DETECTION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2013/136745
Kind Code:
A1
Abstract:
Provided is a microparticle detection system that, when it is possible to appropriately detect the amount of microparticles, performs such a detection. The microparticle detection system (1), which detects the amount of microparticles (S) in a gas (EG) to be measured, is provided with: a detection unit (10) that is mounted to an exhaust pipe (EP); a drive circuit (210, 240) that drives the detection unit (10); and a drive control unit (225) that controls the drive circuit (210, 240). The detection unit (10) has: a first electrical potential member (31, 12, 13) that is at a first electrical potential (PV1); a second electrical potential member (14, 51, 53) that is at a second electrical potential (PVE, PV3); and an insulating member (121, 77, 76) interposed between the first electrical potential member (31, 12, 13) and the second electrical potential member (14, 51, 53), and that electrically insulates the two. The system (1) is provided with an insulating-property inspection means (215, S3, 245, S5) that inspects the insulating properties between the first electrical potential member (31, 12, 13) and the second electrical potential member (14, 51, 53). The drive control unit (225) has a drive possibility determination means (S4, S6) that determines the possibility of the detection unit (10) being driven by the drive circuit (210, 240) on the basis of the magnitude of the insulating properties inspected by the insulating-property inspection means (215, S3, 245, S5).
