Title:
SYSTEM FOR MONITORING MULTIPLE HARMFUL SUBSTANCES
Document Type and Number:
WIPO Patent Application WO/2016/167383
Kind Code:
A1
Abstract:
A system for monitoring multiple harmful substances is disclosed. The disclosed system for monitoring multiple harmful substances comprises: an optical cable including six light source cables, each of the six cables including a three-strand optical fiber bundle, and one detection cable including a one-strand optical fiber, wherein the front ends of six of the 18 optical fibers of the six light source cables are arranged on a first concentric circle on the outside around the light-incident surface of the one detection cable, and the front ends of the remaining 12 optical fibers have a light-output surface arranged on a second concentric circle more outside than the first concentric circle; a plurality of probe devices installed at points, to be measured, at which the harmful substances are to be measured, and connected to the front end part of the optical cable so as to emit a light source from the six light source cables in the air of the points to be measured and reflect the same so as to concentrate reflected light source on the one detection cable; and a measurement device including a light source module, which is installed so as to be connected to the rear end of the optical cable and provides light sources of different wavelengths to each of the six light source cables, and a spectral analysis module analyzing a spectral signal detected through the one detection cable so as to trace components of pollutants and calculate the concentrations thereof, wherein the light source module comprises four light-emitting diodes connected to four of the six light source cables, a laser diode connected to one light source cable, and a tungsten halogen lamp connected to one light source cable, and the probe device comprises: a cylindrical-shaped probe body of which the front and rear are open and having cut holes formed at both sides of the outer circumferential surface; a cover plate coupled to the rear end of the probe body and having a cable connection tube of which the front end of the optical cable is connected to the center; and a concave reflector installed at the front end of the probe body so as to reflect light emitted from the front end of the optical cable to the inside of the probe body, thereby converging the reflected light at the detection cable arranged at the center of the front end of the optical cable.
