Title:
OPTICAL FIBER TYPE AIR PARTICLE COUNTING SENSOR SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/108508
Kind Code:
A1
Abstract:
Disclosed is an optical fiber type air particle counting sensor system, belonging to the technical field of air particle counting. The optical fiber type air particle counting sensor system comprises a laser emitting assembly (1), an emitting optical fiber (2), a sensor cavity (3), a receiving optical fiber (4) and a photoelectric receiving assembly (5) connected in sequence, wherein the laser emitting assembly (1) comprises a laser emitting assembly cover (101), a laser drive plate terminal (102), a laser drive circuit board (103), a laser (104), an aspherical lens (106) and a laser emitting assembly shell (105) connected in sequence; the laser drive plate terminal (102) and the laser (104) are both arranged on the laser drive circuit board (103); and the aspherical lens (106) is arranged on the laser emitting assembly shell (105). The optical fiber type air particle counting sensor system facilitates assembly, adjustment, repair and maintenance by means of a modularized design, thereby improving the working efficiency. Electrical connection, laser transmission and scattered light collection and transmission of a sensor can be effectively isolated, therefore having strong anti-disturbance capability.
